Ada bathroom remodel for homes in Thompsons, TX 77481 — about 20 miles from our shop at 1530 W Sam Houston Pkwy N, Houston, TX 77043.
Two houses, same request, completely different job. A 1968 ranch inside the Loop and a 2006 two-story in Cinco Ranch both need an accessible bathroom, and almost nothing about the two builds overlaps. The older house gives you generous framing lumber, plaster or thick drywall, cast iron drain lines, and a small bathroom laid out around a steel tub. The newer house gives you a bigger primary bath, engineered framing, PVC drains — and a post-tension slab that changes what you can do to the floor. Knowing which house you have tells you where the money and the surprises will be.
What the work involves
In older inner-Houston stock, demo is where the job is decided. Once the walls are open we look at the drain line. Homes built roughly before the mid-1970s here commonly have cast iron under the slab, and cast iron that has been sitting in Gulf Coast soil for fifty years is often scaled, sometimes bellied, occasionally failing. If we are already cutting concrete to move a shower drain, replacing the run while it is exposed is the cheap version of that repair. Supply lines get the same look — galvanized pipe is a replace-now item once it is visible.
Ceilings in that era are frequently popcorn. Anything applied before the early 1980s gets tested before it is disturbed rather than scraped on assumption. Wiring from the late 60s and early 70s occasionally includes aluminum branch circuits, which changes how the new fan and lighting circuits get terminated.
In newer suburban stock the surprises move elsewhere. Framing is tighter and often engineered, so cutting a wider door opening is a structural conversation rather than a carpentry one. The slab is likely post-tension, so any curbless shower starts with locating tendons. And the walls that look full of blocking usually are not — builder bathrooms rarely have backing where a grab bar wants to go.
What drives the cost
In older homes, the cost driver is what is behind the wall. Cast iron drains, galvanized supply, undersized electrical service, and a tested-positive popcorn ceiling each add scope that nobody wanted and nobody can see from the doorway. The framing itself is usually cooperative.
In newer homes, the cost driver is the structure and the slab. Widening an opening in an engineered wall, and locating tendons before touching a post-tension slab, both cost real money. On the other hand the plumbing behind the wall is generally sound, the electrical is generally adequate, and demo produces fewer discoveries.
Common to both: whether the drain relocates, how the curbless entry is achieved, tile format, and the level of access you are building to. And in both, the blocking is trivial to add now and expensive to add later.
Ranges are wide on either house type, but they are wide for different reasons — hidden condition in the old one, structure and slab in the new one.
Building for Gulf Coast conditions
Both houses sit on the same clay, and that clay is why an accessible bathroom gets built with movement in mind. Expansive soil under Houston swells through a wet winter and shrinks through a dry August, and slabs move with it. In older homes that shows as a door that binds seasonally and a hairline running the length of a tile field. In newer post-tension homes the slab moves as a stiffer plate, which is better for cracking and worse for anyone who wants to cut it.
Flood history matters here too. In parts of the metro that took water in 2017 or in the years around it, homeowners often choose tile over wood right through the bathroom and the hall, and ask for outlets set higher than standard. That is a reasonable request and easy to build if it is decided before rough-in.
Humidity closes the loop on both. An accessible shower is an open, unenclosed, frequently-used wet room. Exhaust sized for the room and ducted outside is not an upgrade line item on the Gulf Coast — it is what keeps the tile, the paint, and the cabinet you just paid for from failing early.
Thompsons housing stock
Thompsons is a very small Fort Bend County town near the Brazos south of Sugar Land, and there is no typical house here to describe honestly. It is rural — acreage, a limited number of homes, a wide spread of construction dates and building types, and a reasonable likelihood of private well and septic rather than city utilities. What that means in practice is that we approach projects here property by property rather than by neighborhood pattern. Water hardness, septic capacity if you are adding a bathroom rather than replacing one, service size at the panel, and how the structure is actually framed are all things we confirm on site instead of assuming. Elevation and floodplain status vary along the river corridor and should be checked for the specific parcel. The Gulf Coast constants still apply: expansive clay moves seasonally, humidity stays high year-round, and the details that manage both are what keep a remodel looking right in year five.
How we work
We start with a measured visit and, on older houses, we ask to see any plumbing history you have. If a camera inspection of the drain line makes sense before we price the job, we would rather run it than write an allowance and hope.
From there: plan, written scope, permits appropriate to your jurisdiction, then demo. We schedule a deliberate pause after demo on older homes so you can see what we found before the scope is locked. That is the honest way to handle a house that has been standing for fifty years.
Then framing and continuous blocking, plumbing rough-in and inspection, waterproofing with an overnight flood test, tile, trim out, and a walkthrough with the person who will use the room. Newer homes usually run straighter through those stages, because most of the unknowns were resolved before demo rather than during it.
Common questions
Do you have to scrape the popcorn ceiling?
Only if the work requires it. If the ceiling is being opened for a fan or lighting and the material predates the early 1980s, it gets tested first. Depending on the result it may be encapsulated, or handled by a licensed abatement contractor rather than by us. We will not scrape an untested ceiling of that era, and we will not tell you it is fine because it looks fine.
How do I know whether my slab is post-tension?
Most Houston-area homes built from the mid-1980s onward are, and many have a stamped or placarded warning near the electrical panel or in the garage. Original construction documents settle it. If nothing is available, the slab can be scanned before any cutting. We do not take a guess on this one — cutting a tendon is a structural repair, not a patch, and it is entirely avoidable.
Should we replace the cast iron drain while the bathroom is open?
If we are already cutting concrete to relocate the shower drain, and the exposed cast iron is scaled or bellied, replacing that run while it is uncovered is far cheaper than doing it as its own job later. If the line looks sound and we are not opening the slab, there is no reason to chase it. The decision belongs at the demo stage, with the pipe in view.
Is a newer home easier to make accessible?
Usually the room is larger, which helps enormously. But the two hardest items — widening an opening in engineered framing and going curbless on a post-tension slab — are both harder in newer construction. The trade is fewer hidden-condition surprises. On balance, newer homes give you a more predictable job and older homes give you more forgiving framing.
