Houston 77018 sits about 14 miles from our shop, and small bathroom remodel is work we do there regularly.
Two bathrooms, both under forty square feet, both getting a new tub, tile and vanity. One is in a 1968 ranch off Long Point. The other is in a 2006 house in Cinco Ranch. The scope sheets end up nothing alike. The older bath hides cast iron waste, galvanised supply, a mud pan with weep holes packed solid, sometimes aluminium branch wiring at the receptacle. The newer one has PVC drain, PEX or copper supply, a one-piece fibreglass unit, and a post-tension slab nobody cuts without locating tendons. House age decides most of the cost long before anyone picks a tile.
What we see 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.
How the job is built
Both jobs open the same: isolate the room, protect the path from door to truck, kill the circuit, shut and drain the supply. Then they split. In the older house demolition usually goes to the studs, because that is the only way to see drain material and the framing behind a tub surround. Sound cast iron gets a no-hub coupling to new PVC. Galvanised supply that has scaled shut is replaced back to live copper or PEX, not patched at the last three feet. Aluminium branch wiring gets pigtailed with connectors rated for it and the receptacle comes back GFCI-protected. Soft subfloor on a pier-and-beam bungalow gets cut out and the joist sistered. In the newer house demolition is often partial: the fibreglass unit comes out in sections, drain and supply stay, and work concentrates on the wet wall, blocking and waterproofing. From there the order is shared. Rough plumbing and electrical, inspection where the work is permitted, blocking for a future grab bar, cement backer or foam board, bonded waterproofing, a flood test on the pan, then tile, grout, glass template, vanity, top, fixtures, paint.
Products and materials
Older baths get material decisions the newer ones do not. Behind tile, paper-faced greenboard is not a wet-area substrate; use cement backer board or a foam board system with taped seams. Over that, a bonded liquid or sheet membrane, ANSI-rated for showers, dries faster in this humidity than a traditional mud bed with a sheet liner and buried weep holes. Both work; the bonded system is more forgiving of a service call later. Supply: PEX tolerates the movement a slab house sees and is easier to route through old framing; copper stubs where the valve and stops need rigidity. Valve choice matters against hard water, where a thermostatic cartridge with accessible service parts beats a discontinued builder valve you cannot re-cartridge. Vanities in plywood, not particleboard, because a slow supply-line weep swells particleboard permanently. Glass ordered with a factory-applied protective coating resists the scale that Houston water leaves on plain glass. Porcelain floor tile with the correct thinset for its size, and a crack isolation membrane over slab everywhere in the metro.
Local building realities
Age tracks ground conditions here. Inside the Loop you get 1920s-40s pier-and-beam with shiplap sheathing, and 1950s-70s slab-on-grade in Meyerland, Braeswood and Spring Branch, where the drain runs under concrete and the tub trap is cast iron. Moving a drain there means opening the slab, which on expansive clay also means backfill and compaction done properly, not a shovel of dirt and a patch. Post-1985 Katy, Cypress and Fulshear stock is frequently post-tension: the slab is threaded with stressed cables, so any core or trench needs scanning and an engineer’s direction first. Flood history matters as much as age. In repeatedly flooded areas, tile over a mud bed rather than wood, raise the receptacles above the old high-water mark, and use closed-cell foam in exterior walls instead of batt that holds water. Everywhere in this metro, humidity punishes a bathroom without real exhaust, and older houses very often have none.
What to watch for
On the older house, the common failure is scoping from the surface. Someone quotes a tile bath, opens the wall, and finds a corroded galvanised branch or an unvented S-trap that has to change, so the job stalls mid-demolition. Test water pressure and pull a fixture before pricing. The second failure is dumping a new bath onto original wiring: a single non-GFCI receptacle sharing an aluminium branch with bedrooms, then adding a heat lamp. Pigtail properly, protect the circuit, size the fan duct and take it outside through roof or wall, never into the attic where condensation drips back onto ceiling drywall. On the newer house, the classic error is cutting a post-tension slab to move a shower drain without scanning. A severed tendon is a structural repair, not a plumbing one. Also common in both: setting the toilet flange at the old height after adding tile, then stacking wax rings to make up the difference. Reset the flange on top of the finished floor. Skipping the flood test to save a day is how you find the leak after tile.
How a project runs
We look at the room, pull a fixture or check pressure where the house is old enough to warrant it, and write the scope against what we actually saw. Permitted work gets applied for where the house sits, whether that is the City, unincorporated Harris, or Fort Bend. Materials get selected and ordered before demolition, because a bathroom sitting open waiting on a vanity top is a bathroom you cannot use. Demolition, rough-in, inspection, waterproofing and flood test, tile, then finish. One crew works the room at a time in a space that small.

Cost factors
Whether the drain moves is the single biggest lever, and it costs far more through a slab than through a crawlspace. After that: how much of the wall opens, since full demolition in a 1960s house often surfaces galvanised supply, brittle waste, or framing repairs that were never optional. Electrical scope moves the number, particularly when the panel has no room and a subpanel or circuit rework is needed. Tile choice matters less than tile size and pattern; large-format and herringbone both consume labour. Frameless glass costs more than framed and more again when walls are out of plumb, which older houses usually are. Fixture and valve selection, whether the exhaust duct has a path to the exterior, and permit and inspection requirements for the jurisdiction the house sits in all move it as well. Ranges quoted over the phone are guesses; a walkthrough is what makes a number real.
Common questions
Is a small bathroom in a newer home always cheaper to remodel?
Usually, but not always. Newer plumbing and wiring remove the surprises that drive older jobs up. What newer houses add is the slab constraint and, sometimes, builder-grade framing that is out of plumb enough to complicate frameless glass. The savings come from fewer unknowns, not from less work in the room itself.
My house is from 1965. Does everything behind the wall have to be replaced?
No. Cast iron that is intact and draining can stay, joined to new PVC with a proper coupling. Galvanised supply is different: it scales closed from the inside, and a section that looks fine can be nearly blocked. We check pressure and look at a cut end before deciding, rather than replacing on principle or leaving it on faith.
How do I know if my slab is post-tension?
Homes built in this metro from the mid-1980s onward often are, particularly in Katy, Cypress and Fulshear. There is frequently a stamp or placard near the garage or panel. If there is any doubt and the plan requires cutting concrete, the slab gets scanned before a saw touches it. That step is cheap next to repairing a cut tendon.
