Bathroom renovation for homes in Houston, TX 77021 — about 18 miles from our shop at 1530 W Sam Houston Pkwy N, Houston, TX 77043.
A bathroom renovation is mostly a plumbing and waterproofing job wearing a decorating costume. Everything you will eventually look at sits on work you will never see again: the slab, the drain, the framing, the membrane. Get those wrong and good tile does not save it. Get them right and an ordinary-looking bathroom runs twenty years without drama. What follows is what actually happens in the room, in the order it happens, and why some of those steps carry more weight on a Houston slab than they would in a dry climate. Almost none of it looks like anything until the last week.
Working in Houston
Houston is not one housing stock, so it is not one kind of remodel. In the Heights and Woodland Heights you are often working on 1910s–1930s wood-frame homes on pier-and-beam, where leveling, sill and joist repair, and original wiring long past its service life come before anything cosmetic — and where a home in a designated historic district brings design review with it. Montrose, Oak Forest and Garden Oaks add mid-century layers. Meyerland, Westbury, Braeswood and Sharpstown are largely 1950s–60s slab ranch: cast iron drains near the end of their life, galvanized supply, single-pane windows, popcorn ceilings that should be tested before they are disturbed. Memorial and Alief lean 1970s–80s, which brings aluminum branch wiring and polybutylene supply into the conversation. West of Beltway 8 you are usually in 2000s and 2010s construction, where the job is upgrade rather than repair. Houston has no zoning, but plumbing, electrical and structural work is permitted, and deed restrictions still govern a great deal.
What we actually do
Work starts with containment. Floor protection, plastic at the doorways, and attention to the return air path, because gypsum dust travels the whole house. Then demolition to studs and down to slab or subfloor.
With the room open we look before we build: drain material and condition, supply piping, rot at the base plate, and whether the slab under the shower is flat enough to build on. That inspection sets the real scope, rather than discovering it after the tile is ordered.
Rough-in follows. Drain relocation if the layout changed, valve depth set to the finished wall thickness, new supply runs, blocking for grab bars or a floating vanity, and electrical for lighting, receptacles and the exhaust fan. Inspections happen where the jurisdiction calls for them.
Then the shell: cement board or foam board, a bonded waterproofing membrane on wet walls and pan, corners and drain flange detailed, and a flood test on the pan before any tile. Tile goes down with full mortar coverage under the pan and thresholds, movement joints at the perimeter and changes of plane, then grout and sealant in the corners rather than grout.
Finish work is the short part: vanity, top, toilet, valve trim, glass measured after tile, mirror, paint, and the fan tested for actual airflow.
Choosing materials
Repairs that hold up here are specific. A leaking valve is normally a cartridge, and cartridges are stocked for the common brands, so replacing the trim and cartridge behind an access panel is a real fix. Damaged glass hardware, sweeps and seals are replaceable. A single cracked tile can be cut out and reset if the field around it sounds solid and the crack is not tracking a slab joint. Regrouting a floor with sound tile is worthwhile; regrouting a shower to stop a leak is not, because grout has never been the waterproofing layer. Tub refinishing with an epoxy coating restores appearance on a sound tub and is a finite-life coating, not a new tub. What cannot be repaired in place: a pan liner installed over a flat mud bed with no pre-slope, tile set on paper-faced drywall, a delaminated mud bed, a rotted bottom plate, or a cast iron drain with a belly.
Why this is different on the Gulf Coast
Two Houston realities shape a bathroom more than anything else. The first is the slab. Post-tension and conventional slabs on expansive clay move with the seasons, and that movement is what cracks a grout line straight across a floor or opens a hairline at the tub. The answer is not thicker grout. It is an uncoupling or crack-isolation membrane under floor tile, honest movement joints where the field meets walls and thresholds, and flexible sealant instead of grout in every inside corner.
The second is moisture. With dew points sitting in the seventies for months, a bathroom that vents into the attic instead of through the roof or wall is quietly wetting your framing. Exhaust gets sized to the room, ducted to the outside in insulated duct, with a working backdraft damper.
If your house took water in a past storm, say so early. It changes choices: tile instead of engineered wood, a plywood-box vanity rather than particleboard, and outlets set higher than habit dictates.
Where these jobs fail
The recurring ten-year failure is a niche built into an exterior wall, where the recess eats the insulation and creates a cold surface that condenses in this climate. Put it in an interior wet wall, waterproof it fully, and slope the sill. Second is grout used at every change of plane, at the wall-to-floor and inside corners, where it cracks out within a year or two because those joints move; those get silicone. Third is a fan duct run long and sagging through a hot attic so condensate pools at the low point and drips back through the housing, which people mistake for a roof leak. Fourth is no access to the valve, turning a routine cartridge swap into tile demolition. Fifth is treating silicone as permanent. Left to fail, a joint at the base of a shower wall lets water into the wall slowly for years, which is exactly the sort of long low-level leak this humidity keeps wet.
What to expect
It starts with a walkthrough, not a price sheet. We look at the room, the drain, the attic above it if there is access, and talk about what you actually use the space for. From there you get a written scope that names materials and what is excluded.
Selections get locked before demolition. Tile, valve trim, vanity and glass all have lead times, and a job that waits on a back-ordered valve sits open longer than it should.
Then demo, rough-in, inspection where required, waterproofing and flood test, tile, and finish. Glass is templated after tile because the walls are only truly square once they are tiled.
You get a walkthrough at the end with the fan running and the shower running.

What moves the price
The biggest single lever is whether plumbing moves. Keeping the toilet, shower drain and vanity where they are keeps the job predictable. Moving a drain means opening the slab, and on a post-tension slab that means locating tendons first, which is careful work.
After that: shower size and tile format, because large-format tile needs a flatter substrate and more prep; whether you want a glass enclosure and whether it is framed, semi-frameless or frameless; and what is behind the walls. Cast iron drain lines and galvanized supply in an older house can turn a cosmetic budget into a mechanical one.
Smaller movers add up. Niche count, curbless entry, a fan and light on separate switching, moving a window, and the vanity top material. Any honest bathroom number lands in a wide range until someone has seen the room and knows what the walls are hiding.
Common questions
How long will I be without the bathroom?
Longer than the demolition suggests and shorter than a horror story. It depends on the size of the shower, whether plumbing moves, whether inspections are involved, and how long selections take to arrive. We give you a schedule tied to your specific scope once the room has been seen. If it is your only bathroom, we plan the sequence around that.
Do I need a permit for a bathroom remodel in Houston?
It depends on what you are doing and where you live. Houston has no zoning, but plumbing, electrical and structural work is permitted, and unincorporated Harris County and Fort Bend County handle things differently again. Cosmetic swaps are treated differently from moving a drain or adding a circuit. We tell you what your specific scope requires before work starts.
Can you save the existing tile floor?
Sometimes. If the tile is sound, well bonded and the layout is not changing, keeping it is reasonable. The problem is usually the transition at the old tub or pan, where you will see the outline of what was removed. Tapping the floor tells us a lot; hollow-sounding areas mean the bond has already failed and the floor should come up.
