What is the bathroom remodel cost Katy homeowners should budget in 2027?
Katy homeowners should budget $10,500 to $48,000 for a 2027 bathroom remodel. A secondary bath with a new tub surround, porcelain floor and single vanity runs $10,500–$15,500; a primary bath converting the garden tub to a walk-in shower runs $26,000–$38,000; large primary suites reach $48,000.
What is included in a Katy bathroom remodel price?
A Katy bathroom remodel price includes demolition, a moisture check of the slab, uncoupling membrane and tile, a waterproofed shower or new tub surround, vanity and top, fixtures set by trade partners, and cleanup. Drain moves, new circuits and city permits are coordinated by our GC partners and shown as separate lines.
Why does Katy pricing differ from the Houston metro range?
Katy bathroom pricing has a higher floor and a lower ceiling than the Houston metro range. Katy's production homes carry larger baths than older Houston ranches, and crews drive farther from central supply houses; on the other end, the top of the Katy market is Cinco Ranch golf and lakefront homes, so few estate-scale custom baths push the ceiling up.
Bathroom Remodel Cost in Katy, TX: 2027 Pricing Guide
Each Katy bathroom quote is a written list of line items: tear-out, slab prep, membrane, tile, shower build, vanity, fixtures and haul-off, priced separately so a change in one line never hides in a total. Before a date is set, the property address tells us which rules apply, because a home inside Katy city limits and a Cinco Ranch home in unincorporated county follow different permit paths.
Henry Remodeling provides specialized, hands-on installation services working under the umbrella of established General Contractors. While our dedicated craftsmen deliver flawless tile, cabinetry, and surface installations, our GC partners pull all required city or county permits and coordinate the state-licensed plumbing and electrical trades along with the structural scope.
- Address check: City of Katy limits, or unincorporated Harris, Fort Bend or Waller County, plus any HOA and MUD
- Tear-out of tub, surround, vanity and floor to the slab, with daily debris removal
- Calcium-chloride or RH moisture readings on the exposed slab before any tile is set
- Crack-isolation and uncoupling membrane under the floor, with perimeter movement joints
- Shower walls and pan waterproofed with a bonded sheet membrane up past the showerhead
- Porcelain floor and wall tile set with mortar matched to the tile size
- Vanity, top and mirror installed, plus trim-out of fixtures by the trade partners
- Final walkthrough with the punch list closed before the last invoice
Katy Bathroom Projects Compared by Scope
Four scopes account for most Katy bathroom budgets. Usually the question is whether it’s a secondary bath where the tub stays, or a primary bath where the owners want the builder’s garden tub gone.
| Type | Best for | Houston note | Typical price |
|---|---|---|---|
| Secondary-bath update | Kids’ and guest baths in 10–20 year old Cane Island or Seven Meadows homes | Tub stays; new surround on membrane; floor tile uncoupled over the slab | $10,500–$15,500 |
| Hall or Jack-and-Jill bath to the studs | Shared baths with failing grout, soft drywall or a dated double vanity | Wet walls opened so any hidden leak or mold is found before tile | $15,500–$26,000 |
| Primary bath, garden tub to walk-in shower | Cinco Ranch-era primaries with a corner tub and a small fiberglass stall | Drain relocation is permitted plumbing handled through GC partners | $26,000–$38,000 |
| Full primary suite | Golf-course and lakefront homes with larger footprints | Large-format porcelain needs a flattened, uncoupled slab to avoid lippage and cracks | $37,000–$48,000 |
What a Correctly Priced Katy Bathroom Buys You
Tile that survives clay movement
The membrane and movement joints add a few hundred dollars per floor and keep new tile from cracking along the same slab line the old tile did.
A shower that stays dry behind the walls
Months of humid air and daily steam reach any gap in a shower’s waterproofing. A bonded membrane on walls and pan keeps moisture out of the studs and drywall.
No surprises after demolition
Moisture readings, leak checks and the address-based permit question are answered before the price is final, so most change orders are avoided.
Resale in a production-home market
In subdivisions where dozens of houses share the same floor plan, an updated primary bath helps a listing stand apart from its neighbors.
Katy Bathroom Remodel Prices by Scope (2027)
Our Katy range runs $10,500–$48,000 for 2027. Bath size matters, but shower type and whether a drain moves matter more; the clay-related slab prep is listed as its own line so you can see it.
| Scope | Typical Range (Katy, 2027) |
|---|---|
| Secondary bath: new tub surround on membrane, porcelain floor, single vanity | $10,500–$15,500 |
| Hall or Jack-and-Jill bath gutted to studs, double vanity, new tub or shower | $15,500–$26,000 |
| Primary bath: garden tub removed, walk-in tile shower, double vanity, quartz | $26,000–$38,000 |
| Primary suite: oversized shower, freestanding tub, large-format porcelain | $37,000–$48,000 |
| Add-on: floor flattening plus crack isolation where the slab has heaved | $900–$2,400 |
Thumbtack’s Houston data (updated July 6, 2026) puts typical complete bathroom remodels at $4,503–$15,237, with a high end of $35,696, and homeyou’s Katy guide (updated August 28, 2026) shows a typical range of $3,239–$15,760. Our Katy floor sits above both because every scope here includes a waterproofed shower and an uncoupled floor, which smaller cosmetic jobs in those data sets often leave out.
Katy-area pricing as of November 2026. Henry Remodeling estimates; the signed itemized quote governs.
Line Items That Move a Katy Bathroom Budget
The Katy bathroom ranges come from 2027 material pricing for membrane, tile, setting materials, vanities and fixtures, plus installer labor for west-side jobs, including drive time from the I-10 and Grand Parkway corridor. Prep that only some homes need, such as flattening a heaved slab or drying a wet one, is a separate line. We then held the totals up against outside Houston and Katy figures, Thumbtack and homeyou among them.
| Cost driver | When it applies | Adds to the job |
|---|---|---|
| Which shower gets built | Every bath; tub surround, tiled alcove or walk-in | $3,500–$14,000 for the shower alone |
| Garden tub removal | Most 1990s–2000s Cinco Ranch-era primary baths | $700–$1,600 for removal, deck demo and patch |
| Drain or valve relocation | Walk-in shower in a new spot; permitted work through GC partners | $1,400–$3,800 |
| Slab flattening and crack isolation | Visible floor cracks, tented tile or a slab out of flat | $900–$2,400 |
| Slab drying or moisture mitigation | High readings, often east-side homes with 2017 reservoir water | $600–$1,800 |
| Vanity and top | Single stock to double semi-custom with quartz | $1,200–$6,500 |
| Tile size and pattern | Large-format, herringbone or full-height wall tile | +$6–$14 per sq ft of labor |
| Access and scheduling | Gated sections, HOA work hours, spring and summer backlog | $0–$400, mostly calendar time |
How Katy Pricing Compares, and Budget Levels
National Baseline vs. Katy
HomeAdvisor puts the Houston full bathroom remodel average at $11,900 against $12,900 nationally, and homeyou’s Katy typical range tops out near $15,760. Those averages are pulled down by small jobs: a vanity swap or a regrout counts the same as a gutted primary bath. Katy’s primary baths are larger than the metro average, so a complete primary remodel here lands well above both figures.
What the Katy Spec Adds to the Price
Low Katy bids usually save money in three places: no membrane under the floor tile, a shower waterproofed only with backer board and paint-on coating at the seams, and no moisture check of the slab. On prairie clay, those shortcuts turn into a cracked floor or a soft shower wall within a couple of years.

Bathroom Remodeling Price by Area in Katy
Within Katy the number shifts with bath size and the finish level each neighborhood expects. These are Henry Remodeling estimates for a typical primary or main-bath remodel, listed from the costliest part of Katy to the least, following the neighborhood price spread we track for Katy streets.
| Area (ZIP) | What drives the price there | Typical range |
|---|---|---|
| Fairway and lakefront Cinco Ranch (77494) | Top of the Katy market; larger primary suites with freestanding tubs | $34,000–$48,000 |
| Cinco Ranch interior villages (77494) | First-generation builder baths from the 1990s and 2000s | $24,000–$38,000 |

| Cane Island and newer entry-level sections (77493) | Newer homes; mostly secondary-bath updates and early tile repairs | $10,500–$22,000 |
Bathroom Remodeling Budget Tiers in Katy
Katy budgets sort into three bands for 2027. Each band includes the membrane and the moisture check. They differ in how much of the room gets torn out and rebuilt.
Low Budget
$10,500–$15,500
Secondary bath with the tub kept, new surround on membrane, porcelain floor over an uncoupling mat, stock vanity. Suits rentals and kids’ baths.
Mid-Range
$15,500–$32,000
Hall bath to the studs or a primary with the garden tub replaced by a tiled walk-in, double vanity and quartz. Where most Katy projects fall.
High-End
$32,000–$48,000
Full primary suite with an oversized shower, freestanding tub, large-format porcelain and semi-custom double vanity.
Costs Katy Quotes Leave Out, and Where Shortcuts Fail
Hidden Bathroom Remodeling Costs Not in Most Katy Quotes
- A slab that is out of flat: prairie clay can lift one corner of a bath floor. Large tile will not sit flat over it until the high spot is ground and the low side leveled, which adds $900–$2,400.
- Rot behind the fiberglass surround: a failed caulk line at the tub deck can soak the bottom plate for years. Opening the wall is the only way to see it; studs or sheathing repairs are priced once exposed.
- The city permit inside Katy limits: the City of Katy requires permits for remodeling work, so a home in city limits carries permit time and fees that a nearby unincorporated address may not. Our GC partners handle that part.
- Peak-season scheduling: west-side installers are commonly booked out through spring and summer, so a start date in those months can sit a few weeks out even after the quote is signed.
Why Cheap Quotes Fail in Katy
- Tile laid straight onto the slab with no uncoupling layer, which telegraphs the next clay-driven crack right through the new floor
- Cement board in the shower with seams taped and nothing else, leaving the studs exposed to steam
- A price that assumes the slab is dry, then a change order when the tile will not bond
- No line for the address check, so the permit question surfaces after demolition
DIY Bathroom Remodeling Risks in Katy
- Grinding and leveling a heaved slab without creating new low spots takes a long straightedge and practice
- A shower pan needs a steady slope to the drain and a flood test before tile; skipping the test hides leaks until they reach the drywall
- Large-format porcelain over 24 in needs back-buttering and a leveling system to avoid lippage
- Any drain move or new fan circuit is permitted trade work inside Katy city limits, so our GC partners bring in the trades for it
Katy-Specific Bathroom Cost Factors
Insider tip
Before you collect bids, walk the bath floor barefoot with a flashlight held low. A hairline crack that runs through tile and grout in a straight line is usually a slab crack telegraphing up; one that wanders only through grout lines is usually movement in the setting bed. Point both out at the walkthrough, because the first calls for crack isolation over that line and the second for full tear-out to the slab.
5 Katy Conditions Built Into Every Bathroom Price
West-side prairie clay
Katy’s clay is among the most reactive in the Houston region. Slabs shift enough to crack grout and tile in homes under ten years old, so the floor gets an uncoupling membrane and movement joints at the walls.
Humidity and shower steam
Dew points stay high for long stretches, and a bathroom adds steam twice a day. Bonded sheet membranes, a fan that actually vents outdoors and mold-resistant board behind the vanity wall keep that moisture out of the walls.
Reservoir flood history
Homes on Katy’s east side sit upstream of the Addicks and Barker reservoirs, where 2017 flooding reached houses outside the mapped floodplain. Slabs in those homes are moisture-tested before any tile goes down.
Three counties and a small city
City of Katy addresses follow city permits and inspections under 2021 codes. Outside those limits, which covers most homes with a Katy mailing address, the county governs; Harris and Fort Bend generally send no inspector for interior finish work, and a few addresses fall in Waller.
Community associations and MUDs
Most Katy homes fall under an HOA or community association, such as the Cinco Residential Property Association, plus a MUD. Work hours, dumpster placement and gate access are confirmed before day one.
When a Full Bathroom Remodel Is the Right Call in Katy
- Floor tile has cracked along a line that keeps reappearing after repairs
- The garden tub is never used and the fiberglass shower stall beside it is too small
- Grout is dark and soft at the shower base, or the wall behind it flexes when pressed
- A double vanity has swollen at the toe kick from years of mopping and splashes
- You are preparing a 15–25 year old production home for sale against newer houses nearby
- Not the right scope: the room is sound and only the shower needs work (see shower remodeling) or only the tub should become a shower (see tub-to-shower conversions)
Illustrative Transformation: Bathroom Remodeling in Katy
One typical Katy primary bath, before and after. The example is illustrative and describes no specific client’s home.
Before: the Starting Bathroom Remodeling Scope
A 2002 production primary bath: a corner garden tub on a tiled deck, a 36 in fiberglass shower stall, a builder double vanity with a cultured-marble top, and 13 in ceramic floor tile with a crack running diagonally from the tub deck to the door.
After: the Finished Bathroom Remodeling Scope
The tub and stall come out and the slab reads dry, so the crack line is ground flat and covered with crack isolation before an uncoupling membrane goes across the whole floor. A 60 in walk-in shower with a bonded wall membrane, linear drain moved by the GC partners’ plumber, 24 x 24 in porcelain, a quartz-topped double vanity and new mirrors finish the room. About five weeks on site.
What Sets Henry Remodeling Apart: Bathroom Remodeling in Katy
Address-First Estimates
City limits, county, HOA and MUD are confirmed from the address before the price is final, so any permit requirement is already in the quote when you sign it.
Clay-Ready Floors
Uncoupling membrane, perimeter movement joints and a flattened slab under every tile floor, because Katy clay keeps moving after the job is done.
Measured Slab Moisture
Readings are taken and written on the estimate before tile is ordered, with mitigation priced as its own line when the slab needs it.
Permits and Trade Work Through GC Partners
Henry Remodeling provides specialized, hands-on installation services working under the umbrella of established General Contractors. While our dedicated craftsmen deliver flawless tile, cabinetry, and surface installations, our GC partners pull all required city or county permits and coordinate the state-licensed plumbing and electrical trades along with the structural scope.
Respect for Occupied Homes
Dust walls, floor protection along the path to the bath and daily haul-off, so the rest of the house stays livable while the room is rebuilt.
How a Katy Bathroom Remodel Runs, Start to Finish
A Katy bathroom job runs in seven stages; tile is ordered only after the jurisdiction and slab condition are settled.
| Step | What happens | Typical time |
|---|---|---|
| 1. Site visit at your Katy address | Measure the room, photograph cracks, check for soft walls and note the address jurisdiction | About 1 hour |
| 2. Itemized quote | Line-item price with tile, vanity and fixture selections; permit path noted | 2–4 days |
| 3. Approvals and ordering | HOA notice where required; GC partners file any permit; tile and vanity ordered | 1–4 weeks |
| 4. Tear-out and slab check | Room taken to studs and slab; moisture readings; leak and rot repairs scoped | Days 1–3 |
| 5. Rough work and prep | Drain or valve moves by trade partners; slab flattened; membrane installed and flood-tested | Days 3–8 |
| 6. Tile, vanity and fixtures | Floor and wall tile set and grouted; vanity, top and glass installed; fixtures trimmed out | Days 8–22 |
| 7. Inspection and walkthrough | City final where the home is in Katy limits; punch list closed with you | Final 1–3 days |
Common Problems We Solve: Bathroom Remodeling in Katy
Cracked floor tile in a newer home
Clay movement under the slab shows up first in rigid tile. The cracked tile and the setting bed come up, the slab line is treated with crack isolation, and the new floor goes down over an uncoupling membrane.
A soft wall at the shower base
Water has been getting past the old surround or tile for a long time. The wall is opened, wet framing replaced and the new shower built with a bonded membrane from pan to ceiling height.
A garden tub nobody uses
The tub, its deck and the platform framing come out, and the space becomes a larger walk-in shower or storage. Any drain move goes to the GC partners.
A swollen vanity base
Particleboard builder vanities absorb splashes at the toe kick. The replacement is plywood or a sealed furniture-style base standing clear of the floor.
What Can Go Wrong: Bathroom Remodeling in Katy
Katy bathroom remodels tend to go wrong in six ways, each with its own prevention.
New floor cracks along the old line
Tile set without uncoupling over a slab that keeps moving. A membrane and movement joints stop the crack from transferring.
Tile that sounds hollow by the first winter
Setting mortar poured over a damp slab never fully bonds. A moisture reading before setting, and mitigation when needed, prevents it.
A shower leak that shows up in the closet next door
Seams left untreated behind the tile. A continuous membrane and a 24-hour flood test of the pan catch it.
Lippage on large-format tile
Big porcelain amplifies any hump in the slab. Grinding high spots and using a leveling system keeps edges flush.
A stop-work notice from the association
Dumpster on the street or crews outside allowed hours. Confirming HOA rules before the start date avoids it.
Permit questions after demolition
A home inside Katy city limits needs a city permit for remodeling. Checking the address first keeps the schedule intact.
Common Mistakes and Homeowner Checklist: Bathroom Remodeling in Katy
6 Common Contractor Mistakes in Katy Bathroom Remodeling
- Comparing bids that do not list a membrane: the cheapest quote is often the one without uncoupling, which is the line Katy clay tests first
- Assuming the county inspects interior work: in unincorporated Katy addresses it generally does not, so the only quality check is your installer’s own process
- Ignoring a 2017 water history: east-side slabs can still hold moisture under old flooring; test before tile
- Keeping a garden tub out of habit: it takes the space a usable walk-in shower needs
- Ordering tile before demolition: the slab condition decides the setting method, and sometimes the tile size
- Scheduling in peak season without lead time: spring and summer backlogs push start dates out
Bathroom Remodeling Pre-Project Checklist for Katy Homeowners
- Ask which membrane goes under the floor tile and whether movement joints are included
- Ask how the shower walls and pan are waterproofed and whether the pan is flood-tested
- Ask for the slab moisture readings to be written on the estimate
- Confirm whether your address is inside City of Katy limits or in unincorporated county
- Confirm who files any permit; it should be the GC partners, not you
- Check your HOA’s rules on dumpsters, work hours and gate access
- Ask whether drain or valve moves are priced as separate lines
- Get the start date and on-site duration in writing
How Long Does a Katy Bathroom Remodel Take?
Best Case
2–3 weeks
Secondary bath with the tub kept, a dry slab and no drain changes, in unincorporated county.
Typical
4–6 weeks
Primary bath with the garden tub removed and a walk-in shower built, including trade-partner rough-in.
Extended
7–10 weeks overall
City of Katy permit review, slab drying after high readings, custom glass, or a spring start in a booked-out season.
What Causes Timeline Extensions in Katy
- Permit path: City of Katy addresses add permit review and inspections; most unincorporated addresses do not.
- Slab moisture: A wet slab needs drying time or a mitigation coat before tile can be set.
- Custom glass: Glass panels can only be templated once tile is done, then fabrication runs one to two weeks.
- Installer demand: West-side crews are commonly booked out in spring and summer.
Illustrative Katy Bathroom Budgets by Neighborhood
The three Katy bathroom budgets below are illustrative scenarios built from typical local scopes. They are not completed Henry Remodeling projects, and every figure is an estimate.
Garden Tub to Walk-In Shower: Cinco Ranch 77494, Katy
Client Profile: Parents of three in a 2000-era production home, tired of an unused corner tub beside a cramped stall.
Key Challenge: A diagonal crack runs across the floor tile from the tub deck. The slab line gets crack isolation and the whole floor an uncoupling membrane; the shower drain moves about four feet, which the GC partners’ plumber handles.
Location Context: Most Cinco Ranch addresses are unincorporated county, where interior finish work generally has no county inspection. The Cinco Residential Property Association’s rules set dumpster placement and work hours, and those are confirmed first.
Investment Range: $29,000–$36,000 Timeline: 4–5 weeks on site
Hall Bath to the Studs: Old Town Katy 77493, Katy
Client Profile: Owners of an older home near the historic downtown updating its only full hall bath.
Key Challenge: Opening the walls behind the tub shows old water damage at the bottom plate. Framing repairs, a new tub with a membrane-backed tile surround, a porcelain floor over uncoupling and a new vanity follow.
Location Context: If the address is inside Katy city limits, the City of Katy requires a permit for remodeling and schedules inspections under its 2021 codes. Our GC partners file and coordinate that, and the calendar includes the review time.
Investment Range: $17,000–$23,000 Timeline: 3–4 weeks after permit
Secondary Bath Refresh: Cane Island 77493, Katy
Client Profile: Owners of a newer home whose kids’ bath already shows grout cracks and a loose floor tile.
Key Challenge: Even a young slab on west-side prairie clay can move enough to crack rigid tile. The floor is reset over an uncoupling membrane, the tub surround is redone in porcelain on a bonded membrane, and a plywood vanity replaces the builder unit.
Location Context: Newer master-planned sections carry HOA rules on contractor access, and the job is planned around them. No plumbing locations change.
Investment Range: $11,500–$15,000 Timeline: 8–12 working days
Difficulty Factors: Bathroom Remodeling in Katy
Four Katy conditions make a bathroom harder to build well here than in a drier, more stable market.
Floors on the region’s most active clay
Every tile floor has to be detailed for movement: membrane, joints at the walls, and attention to any crack line already in the slab.
Wet air most of the year
Showers have to be waterproofed as a continuous system, and materials outside the shower still need to tolerate high indoor humidity.
Unknown water history
Reservoir flooding in 2017 reached homes that were not in a mapped floodplain, so a dry-looking slab is still tested.
Layered jurisdictions
City, county, HOA and MUD can all apply to one address, and each changes what paperwork the job needs.
Who Needs Bathroom Remodeling in Katy
Families in 10–30 year old production homes
Owners in Cinco Ranch 77494 and Seven Meadows 77494 replacing first-generation builder baths, usually starting with the primary.
Relocating energy-sector employees
Buyers moving near the Energy Corridor who update baths in a Grand Lakes 77494 or Cinco Ranch purchase before moving in.
Owners of newer homes with early cracks
Cane Island 77493 households dealing with grout and tile cracks from slab movement in houses under ten years old.
Owners of older in-town homes
Old Town Katy 77493 owners updating original baths, where permits inside city limits and hidden wall damage shape the budget.
Materials & Methods: Bathroom Remodeling in Katy
Six material layers decide whether a Katy bath still looks right after years of slab movement, steam and muggy air.
| Component | Specification | Why it holds up on Katy clay and in Gulf Coast humidity |
|---|---|---|
| Floor underlayment | Polyethylene uncoupling membrane over a flattened slab, plus crack isolation on any existing crack | Lets the slab move without cracking the tile above it |
| Movement joints | Flexible sealant joints at every wall and every 20–25 ft in larger rooms | Gives tile room to expand instead of tenting |
| Shower waterproofing | Bonded sheet membrane on walls and pan, carried above the showerhead, with sealed seams | Keeps steam and water out of the framing |
| Tile | Porcelain, through-body or glazed, sized to the room and the slab’s flatness | Low absorption and strength over a moving base |
| Setting materials | Polymer-modified thinset suited to the membrane and tile size; urethane or high-performance grout | Holds bond and resists cracking and staining |
| Vanity | Plywood box or a sealed furniture-style base off the floor | Resists the swelling that ends particleboard vanities |

Frequently Asked Questions: Bathroom Remodeling in Katy
In 2027, how much does bathroom remodeling cost in Katy?
Henry Remodeling estimates Katy bathroom remodeling at $10,500 to $48,000 in 2027. Secondary baths with the tub kept run $10,500–$15,500, hall baths taken to the studs $15,500–$26,000, garden-tub-to-shower primaries $26,000–$38,000, and full primary suites $37,000–$48,000. Slab flattening where clay has lifted the floor adds $900–$2,400.
Is a city permit needed for a bathroom remodel at a Katy address?
Whether a Katy bathroom remodel needs a city permit depends on where the property sits. The City of Katy requires permits for remodeling, plumbing and electrical work inside its limits and inspects under 2021 codes. Most Katy-address homes are in unincorporated Harris or Fort Bend County, where interior finish work generally has no county inspection, though drain or wiring changes still go through the right trades and your HOA may set its own rules. Henry Remodeling provides specialized, hands-on installation services working under the umbrella of established General Contractors. While our dedicated craftsmen deliver flawless tile, cabinetry, and surface installations, our GC partners pull all required city or county permits and coordinate the state-licensed plumbing and electrical trades along with the structural scope. Our Houston-area remodel permit guide compares the jurisdictions.
My Katy home took on reservoir water in 2017. What changes for a bath remodel?
In a Katy bath remodel after reservoir water, the slab is moisture-tested before tile, and any remaining drywall, insulation or particleboard that stayed wet comes out and is replaced. Homes upstream of Addicks and Barker flooded even outside the mapped floodplain, so a slab that looks dry still gets a reading. Our flooded kitchen and bath rebuild guide covers drying, testing and flood-tolerant materials.
Why does tile crack in a Katy house that is only a few years old?
In a Katy house only a few years old, tile cracks because west-side prairie clay swells when wet and shrinks in drought, and slabs move with it. Rigid tile bonded straight to the slab cracks along that movement. An uncoupling membrane, crack isolation over existing slab cracks and movement joints at the walls prevent it in the new floor.
What does it cost to replace a garden tub with a walk-in shower in Katy?
Replacing a garden tub with a walk-in shower in Katy usually costs $26,000–$38,000 as part of a primary-bath remodel with a new double vanity. Tub and deck removal alone runs $700–$1,600, and moving the drain to a new shower location adds $1,400–$3,800 through our GC partners.
How long does a Katy bathroom remodel take?
A Katy bathroom remodel takes two to three weeks on site for a secondary bath with no plumbing changes, four to six weeks for a primary bath with a new walk-in shower. City of Katy permit review, a wet slab, custom glass or a spring start can extend the overall schedule to 7–10 weeks.
Why is the bathroom remodel cost Katy contractors quote often higher than online averages?
Katy bathroom quotes often top online averages because those averages include small jobs such as a vanity swap or a regrout. A full Katy primary bath is larger than the metro average and, done correctly, includes an uncoupled floor, a fully waterproofed shower and a slab moisture check. Leaving any of them out is how floors and showers fail early.
Does my Katy HOA need to approve an interior bathroom remodel?
Many Katy associations care less about the bathroom interior than about how the remodel runs: dumpster placement, work hours, parking and gate access. Some, like the Cinco Residential Property Association, publish those rules. Check yours before the start date so the schedule holds.
