Looking at bathtub replacement in Cypress 77429? That’s around 17 miles from us, well inside the area we work daily.
Replacing a bathtub sounds like a swap and rarely is. The tub is the last thing installed in that alcove and the first thing everything else was built around — tile laps over its flange, the surround sits on it, the drain ties into a waste and overflow that runs under the floor, and in a slab-on-grade Houston home that drain is set in concrete.
So the honest version of this job is: demolition of the surround, careful extraction, an inspection of what has been living behind the tile, plumbing work at the drain and valve, a properly bedded new tub, and a rebuilt waterproofed surround. Done right, the new tub outlives the tile around it.
What the work involves
Water gets shut off and the room is protected. The surround comes off first — tile and backer down to studs on the three alcove walls, plus the ceiling edge if there is a shower head. Trim, the tub spout, valve trim, and the waste and overflow plate come off.
The tub is cut free at the flange and removed. Cast iron usually comes out in pieces; acrylic and steel come out whole if the doorway allows. This is the moment we look at what has been hidden: the condition of the studs and bottom plate, the subfloor at the tub apron, whether the old drain leaked, and whether the framing needs sistering or plate replacement.
Plumbing comes next. The waste and overflow is replaced as an assembly rather than reused, and the drain is connected properly at the trap. If the new tub’s drain sits in a different position than the old one, that means opening the floor or slab to relocate it. The valve is typically replaced at the same time — the wall is open, and doing it later means opening it again. Blocking goes in for the valve and any grab bar.
The new tub is set in a full mortar bed or on the manufacturer’s specified support so the floor of the tub does not flex, leveled in both directions, and fastened at the flange per the maker’s instructions.
Then backer board, a continuous waterproofing membrane lapped correctly over the tub flange, tile, and a flexible sealant at the tub-to-tile joint.
What goes wrong, and how it is avoided
Refinishing over a tub that has an active leak, or over a surround with an open joint, is the big one, because the coating hides the evidence. Refinishing a tub that has already been refinished and is peeling is the second, since the new coat inherits the old bond. On liners, the recurring failure is water entering at the perimeter or at the drain gasket, sitting between shell and tub, and being noticed only when it reaches the ceiling below or the adjacent room’s baseboard. On replacements the mistakes are mechanical: no mortar bed, fastening through the deck, the wrong drain hand for a slab rough-in, a mismatched spout nipple, and a grouted rather than siliconed change of plane. Across all three, the common error is treating a soft floor at the tub apron as a cosmetic issue.
What drives the cost
The largest single driver is whether the drain moves. Matching the existing rough-in keeps the floor closed. Relocating it in a slab home means concrete work and licensed plumbing.
Tub material and type is next. A standard alcove acrylic unit, a porcelain-enameled steel tub, a cast iron tub, and a freestanding soaking tub occupy very different places on the scale — and cast iron and freestanding tubs may need floor structure evaluated, plus more hands to set.
What we find behind the old surround matters. Rotted plate, damaged studs, a wet subfloor, or a corroded drain in an older home all add scope discovered mid-job.
Then the surround itself: tile size and pattern, height, whether there is a niche, and whether a glass panel or door is added. Valve replacement, permitting for the plumbing change, and removal of an old cast iron tub through a tight hallway all contribute. Expect a wide range depending on which of those apply.
Materials and specification
At the entry tier you are usually looking at gelcoat fibreglass: light, cheap, easy to carry through a hall door, and prone to flexing, chalking and yellowing with age. Mid tier is typically acrylic bonded over a reinforced backing, which is thicker, warmer to touch, holds colour better and repairs reasonably. Above that sit porcelain enamel over steel, which is hard and cheap to buy but chips at the drain and rings loudly, and enamelled cast iron, which is the most durable surface available and the heaviest thing you will ever bring into a bathroom. Cast iron on a slab is straightforward; on a pier-and-beam Heights or Montrose floor it deserves a look at the joists first. Surround materials follow the same logic: porcelain tile over a proper membrane at any tier, natural stone only if you accept sealing and hard water spotting.
Building for Gulf Coast conditions
Slab-on-grade construction is the first Gulf Coast factor. There is no crawlspace to reach up into, so any change to drain location means breaking and patching concrete, which turns a straightforward swap into a plumbing and permitting job. It is the single biggest reason we push hard to match the new tub’s rough-in to the existing drain when the layout allows.
The second is seasonal slab movement over expansive clay. A tub that is not fully bedded sits on a floor that moves, and that movement telegraphs straight into the tile joint at the tub deck. That joint is the one everyone points to when they say the shower leaks. Full support under the tub and a flexible sealant instead of grout at that joint is what keeps it closed.
Hard water is the third. Scale builds fast on Houston fixtures and glass, and it dictates finish choices — smooth non-porous tub surfaces, glass with a factory-applied protective coating if you are adding a door, and fixture finishes that tolerate frequent cleaning without pitting.
In flood-affected parts of the metro, homeowners increasingly ask for tile surrounds instead of wood-framed built-ins and for outlets set higher on the wall during the same opening.
Working in Cypress
Cypress is mostly unincorporated northwest Harris County, and the housing reflects a building push that ran from the 1990s straight through the 2010s. Post-tension slab, brick across the front, two stories, a tall entry, a garden tub the family stopped using years ago, and cabinet boxes that are particleboard behind a solid door. That last detail matters in this climate: particleboard swells if a supply line weeps or a dishwasher leaks, and it does not come back. When we rebuild a kitchen here we move to plywood boxes. The rest of the pattern is predictable and fixable — builder carpet, a wall between the kitchen and family room that no longer makes sense, a formal dining room nobody eats in. These are newer homes, but they sit on the same expansive clay as everything else, so substrate flatness and movement joints still decide whether your tile looks right in year five. Most neighborhoods have deed restrictions and architectural review for exterior changes.
How we work
We measure the alcove, identify the existing rough-in dimension, and check whether the tubs you are considering will land on that drain. That one measurement shapes the entire estimate, so it happens before any numbers are discussed.
You get a written scope covering demolition, what we expect to find, how hidden damage will be handled and priced if it appears, the tub and valve being installed, the waterproofing system for the surround, and the tile work.
On site: protection, water shut off, demolition, inspection with you present so you see what we see, framing and plumbing repairs, permit inspection where plumbing changes require it, tub set and bedded, waterproofing, tile, then trim and fixtures. The bathroom is out of service for the duration. If you want yours measured, call (281) 235-6971.
Common questions
Should I reuse the old drain assembly?
No. The waste and overflow assembly is inexpensive relative to the labor to reach it, its gaskets are the parts that harden and leak, and it is matched to the tub's dimensions. Reusing it to save a small amount means the next leak requires opening everything again. The drain arm and trap get inspected at the same time while the floor is accessible.
Is a cast iron tub worth it here?
It holds heat well and feels solid, and that appeals to a lot of people. The trade-offs are weight — floor structure and getting it into the room both need thinking about, especially upstairs — and cost. A quality acrylic tub with a full mortar bed under it performs well and is far easier to install in a typical Houston alcove.
Do I need a permit to replace a bathtub?
If you are truly swapping like for like with no change to drain, vent, or water lines, often not. Once the drain moves, the valve type changes, or wiring is altered, plumbing and electrical permitting generally applies. Requirements differ between the City of Houston, unincorporated Harris County, and Fort Bend, so we confirm what governs your specific address before starting.
Can you install a new tub without tearing off the tile?
Almost never in an alcove. The tile laps over the tub's flange, so the tub cannot come out without breaking that lower course, and the new tub's flange has to be covered by new tile and membrane to be watertight. Anyone offering to swap the tub and leave the surround untouched is planning to caulk over the joint, which fails.
