What bathroom remodeling services are available in Houston?
Participating Houston pros handle full bathroom remodels, cast iron drain replacement and lining, walk-in showers, tub-to-shower and shower-to-tub conversions, flood-resilient rebuilds, bath liners, fixture replacement, floor tiling and accessibility upgrades. The most common Houston job is the 1960s ranch hall bath gutted and rebuilt with the drain under the slab addressed. The most common second remodel is a bathroom that was flooded and rebuilt fast the first time, with materials that could not take the next one.
Full bathroom remodels. The post-war ranch hall bath in Oak Forest, Garden Oaks, Westbury or Spring Branch: open the walls, replace supply lines, camera and often replace the drain under the slab, install an exhaust fan that vents outside, and rebuild. In the Heights, Montrose and Eastwood bungalows, it is the one original bathroom brought current while the house keeps its character.
Cast iron drain replacement and lining. Houston homes built before the mid-1970s commonly have cast-iron drains under the slab that clay movement and sixty years of use have cracked or corroded. Slow drains, odors and a damp spot in the floor are the signs. Pros tunnel under the slab to replace, or line the pipe from inside.
Flood-resilient rebuilds. After Harvey, pros in Meyerland, Westbury, Kingwood and the Clear Lake area learned to rebuild bathrooms with materials that survive a second event: cement board rather than paper-faced drywall below the flood line, porcelain over wood-look laminate, PVC trim, and vanities that can be unbolted. A remodel in a flood-prone neighborhood should be built that way whether or not the house has flooded yet.
Walk-in showers and tub-to-shower conversions. The most requested change in Sharpstown, Spring Branch and Clear Lake ranches and for anyone aging in place. Benches, hand-held sprays, grab-bar blocking and slip-resistant floors as standard.
Garden tub removal. Katy-adjacent, Cypress-adjacent and 1990s Kingwood homes have a corner garden tub next to a small stall; one large walk-in shower in that footprint is the signature primary bath job across the suburbs.
Shower-to-tub conversions, bath liners, fixture replacement, floor tiling, accessibility. Comfort-height toilets, slip-resistant porcelain, reinforced grab bars. For a seated bathing option see walk-in tubs.
Why are Houston bathrooms different?
Houston bathrooms are shaped by expansive clay that moves the slab, humidity that never lets the house dry out, cast-iron drains failing under homes built before 1975, and a flood history that has already rebuilt thousands of bathrooms once. Any estimate here should say how the drain was inspected, how the tile will tolerate slab movement, and how the fan vents.
Clay and slab movement. Houston's gumbo clay swells and shrinks with the seasons. A crack across the shower floor or a gap opening between the tub and the tile is the slab moving. Uncoupling membranes under tile, flexible sealant at every change of plane, and no rigid grout against the tub deck are the standard answer. If doors stick too, a foundation evaluation comes before the remodel.
Humidity and mold. A bathroom without a correctly sized exhaust fan ducted outside grows mold behind the walls. Houston code requires the fan on permitted work; good pros size it for the room and put it on a humidity sensor. Mold-resistant backer board and no paper-faced drywall in wet zones.
Cast iron under the slab. The pipe under a 1950s to 1970s slab is often the real problem. A camera inspection before the estimate is the sign of a pro who has worked in Meyerland or Oak Forest before.
Flood zones. In the 100-year and 500-year zones a ground-floor bathroom should be built with materials that survive a few feet of water. After a flood, substantial-damage rules in the City of Houston and Harris County can also affect what work is allowed before elevation is addressed.
Polybutylene and galvanized. Homes from the late 1970s to mid-1990s may carry gray polybutylene supply that fails without warning; older homes carry galvanized. Both get replaced with PEX while the walls are open.
Hard water. Houston's blend of surface water and groundwater is moderately hard, enough to spot glass. Coated glass and brushed finishes hold up.
Permits. The Houston Permitting Center handles plumbing, electrical and structural work inside city limits. Unincorporated Harris County, and separate cities such as Bellaire, West University Place and Pasadena, issue their own.
How much does a bathroom remodel cost in Houston, and how long does it take?
A mid-range full bathroom remodel in Houston typically runs $13,000 to $27,000 within the existing footprint, and a tub-to-shower conversion $6,000 to $14,000. Replacing failed cast iron under the slab adds $4,000 to $15,000 depending on the run, and a flood-resilient material package adds a few thousand over a standard rebuild. Conversions take two to five working days and full remodels three to five weeks.
- Tub-to-shower conversion: $6,000 to $14,000, two to five working days.
- Full remodel in the existing footprint: $13,000 to $27,000, three to five weeks.
- Garden tub removed for one large walk-in shower: usually $9,000 to $18,000.
- Cast iron drain replacement or lining under the slab: $4,000 to $15,000; polybutylene to PEX on bathroom runs: $1,500 to $4,000.
- Flood-resilient materials below the flood line (cement board, porcelain, PVC trim, removable vanity): roughly $1,500 to $4,000 over standard.
- Permit: Houston Permitting Center inside city limits, Harris County or your own city outside. The pro pulls it.
Which Houston neighborhoods do we hear from most?
Oak Forest, Garden Oaks and Spring Branch, 1950s and 1960s ranches with cast iron under the slab. The Heights, Montrose and Eastwood, bungalows with one original bathroom. Meyerland and Westbury, where flood-resilient rebuilds are the norm. Sharpstown and Clear Lake, ranches ready for walk-in showers. Kingwood and the Katy and Cypress edges, 1990s primary baths with garden tubs to remove.
How does the bathroom remodel process work in Houston?
The process has four steps: a consultation that checks the fan path and supply material, cameras the drain in older homes and asks about flooding and foundation history, written estimates compared side by side, construction, and a final walkthrough with the fan tested against the outside. Permits add two to four weeks, and pros avoid starting demolition in a week with a storm in the forecast.
- Consultation. Submit the form or call. Participating pros that serve your Houston zip code visit, measure, check supply lines and the fan path, camera the drain where the home is older, and ask whether the house has flooded or had foundation work.
- Design and estimates. Written estimates with scope, materials, any slab or drain work, movement-tolerant details, and a schedule. Compare them side by side.
- Construction. Conversions take two to five working days. Full remodels run three to five weeks, longer when the slab is opened for the drain.
- Final walkthrough. Fixtures run, fan tested against the outside, permit inspections closed, then final payment.

Frequently asked questions
How much does a bathroom remodel cost in Houston?
Estimates in the Houston area typically run $13,000 to $27,000 for a mid-range full remodel within the existing footprint and $6,000 to $14,000 for a tub-to-shower conversion. Cast iron replacement under the slab and flood-resilient materials are separate line items. Written estimates from more than one pro are the only reliable number.
My tile cracked along a line. Is the bathroom failing or the foundation?
A crack that runs in a line across several tiles in a Houston bathroom is almost always the slab moving on the clay. The lasting fix uses an uncoupling membrane and flexible joints so the finish can move a little without cracking. If doors stick too, have the foundation evaluated before you remodel.
How do I know if the cast iron drains under my slab are failing?
Slow drains in more than one fixture, a sewer smell, damp or discolored spots on the floor, or a pre-1975 home that has never been inspected. A camera inspection settles it, and the remodel is the right time to fix it.
Should my bathroom be rebuilt differently because I am in a flood zone?
Yes, a ground-floor bathroom in a Houston flood zone should use materials that survive water: cement board instead of paper-faced drywall below the flood line, porcelain tile, PVC or composite trim, and a vanity that can be removed. It costs a few thousand more and avoids a full second rebuild.
Do I need a permit in Houston?
Yes for plumbing, electrical or structural changes. The Houston Permitting Center issues it inside city limits, and the pro pulls it. A straight fixture swap generally does not need one.
How long will the bathroom be out of service?
Two to five working days for a conversion. Three to five weeks for a full remodel. Longer if the slab is opened for the drain.
