Bathroom tile flooring for homes in Katy, TX 77494 — about 10 miles from our shop at 1530 W Sam Houston Pkwy N, Houston, TX 77043.
A tile floor quote for a bathroom in Oak Forest and one in Cypress describe the same finished result and almost none of the same work. Inside the Loop we are usually opening up a house built between the fifties and the seventies: mud beds, cast iron drains, a subfloor that may flex, and a real chance of asbestos in old sheet flooring. In the western suburbs we are working over a post-tension slab poured to production tolerances, with trusses overhead and PEX in the walls. Different substrates, different hazards, different costs. Knowing which house you have explains most of what a bid says.
Scope of work
In the older house, demolition is the unknown. Original bathrooms often have a mortar bed over wire lath — heavy, slow to remove, and thick enough that taking it out drops the floor height and changes the threshold and the toilet flange relationship. Any resilient sheet flooring from before the early eighties gets tested rather than disturbed. If the house is pier-and-beam or has a wood subfloor, we check joist span and deflection, refasten loose sheathing, and add a layer where the span calls for it, because tile does not tolerate bounce. Cast iron closet bends and galvanised supply lines are frequently exposed at this stage, and that is the moment to decide whether they get addressed.
In the newer house, demolition is quick — usually a thin-set twelve-inch ceramic over a bare slab, with no membrane and often no movement joints, which is exactly why it cracked. The work shifts to slab preparation: grinding high spots, self-levelling over primer where flatness fails a straightedge, and nothing mechanically fastened, because post-tension tendons run through that slab.
From there both jobs converge: separation membrane, dry layout, setting with the right notch and back-buttering, levelling clips on large formats, soft perimeter joints, grout, flange extender, fixtures reset.
Where the budget goes
In the older house, the drivers are discovery. Mud bed removal, hazardous-material testing on old resilient flooring, subfloor reinforcement, and whatever the drain looks like once it is exposed. A cast iron closet bend in poor condition is not a tile cost, but it becomes part of the job because the floor is open and it will never be cheaper to reach. Floor height changes ripple into thresholds, door undercuts and flange work.
In the newer house, the drivers are flatness and format. A production-poured slab that was acceptable under twelve-inch ceramic will often need levelling compound under large-format tile, and that material and labour is the single biggest surprise line in suburban bids. Post-tension slabs also rule out any fastened approach, which is not a cost so much as a constraint on shortcuts.
Common to both: tile material and pattern, grout type, whether the vanity and toilet come out, and whether the shower is done at the same time. Doing the floor in isolation carries the same setup as a fuller scope.
What Houston conditions demand
Both houses sit on the same expansive clay, but they express it differently. The 1960s slab inside the Loop has had sixty years of seasonal movement and often shows it in doors that bind and a floor with a settled corner. Nothing about a tile job stops that movement; the membrane and the soft joints simply keep the tile from being the thing that cracks. In the newer western-suburb house the slab is younger and post-tensioned, which handles movement differently but does not eliminate it — and the tendons are a hard constraint on what may be drilled.
Flood history splits the same way. In Meyerland, Bellaire and other bayou-adjacent neighbourhoods, tile over slab is often the deliberate choice made after water, because it dries and survives where laminate and carpet do not. In those houses we also look at what is above the floor: outlet heights, the vanity’s base cabinet material, and whether the toe kick is going to wick.
Humidity affects both. Older bathrooms frequently have an undersized or unducted exhaust fan, and while we have the floor open is the sensible time to fix where it discharges.
What we see in Katy
Katy covers a lot of ground. Parts sit in Harris County, parts in Fort Bend, parts in Waller, and only some addresses are actually inside the City of Katy — which affects who permits and inspects the work. The housing runs from late-1970s and 1980s neighborhoods through the master-planned build-out of the 1990s and 2000s and on into current construction. In the 80s and 90s homes we see oak cabinets, laminate counters, a garden tub with a narrow shower beside it, formal rooms nobody uses, and enough polybutylene supply piping that it is worth confirming before you commit to a bathroom. Homes that have taken water at some point come with different priorities: tile or a quality LVP instead of wood, outlets set higher than standard, closed-cell foam in place of batt. The clay moves here, so substrate flatness and movement joints get the same attention as the tile selection. Most neighborhoods have HOA architectural review.
The process
The first visit differs by house. In an older home we want to open a small area to see what is really under the floor before writing anything, and we talk about testing before anyone disturbs old sheet flooring. In a newer home we bring a long straightedge and check flatness in several directions, because that measurement decides whether levelling compound is in the scope.
The written scope then names the substrate work explicitly rather than hiding it in a per-square-foot number, which is the honest way to let you compare bids.
On site, older houses take longer at the front end and newer houses take longer at the preparation stage. Both then follow the same sequence: membrane, dry layout, set, cure, grout, reset fixtures, seal the perimeter with flexible sealant.

Common questions
My 1960s bathroom has thick mortar under the tile. Is that good or bad?
It was excellent work in its day and it often outlasts modern thin-set installations. The complication is removal: it is heavy, slow, and taking it out lowers the finished floor, which changes the door, the threshold and the toilet flange. Sometimes the right answer is to leave a sound mud bed in place and tile over it after preparation. We decide once we can see its condition and thickness.
Why does builder tile in newer suburbs crack so often?
Two reasons, usually together. It was set directly on a slab with no separation membrane, and the grout runs rigidly from wall to wall with no soft movement joint at the perimeter. When clay-driven movement flexes the slab, the tile has nowhere to go. The tile itself is rarely the problem. A replacement done with an uncoupling layer and proper movement joints addresses the actual cause.
Is asbestos really a concern in an older Houston bathroom?
It can be, in sheet flooring, its backing, and the mastic under it, in houses built before the early eighties. It is not a reason to panic and it is a strong reason not to sand, grind or dry-scrape an old floor. The responsible sequence is to test first and handle the result accordingly. Any contractor who shrugs at that question in a 1965 house is telling you something.
Do post-tension slabs limit what you can do?
They limit fastening. Nothing gets drilled or driven into a post-tension slab without knowing exactly where the tendons run, and for a tile floor there is no reason to. Our whole build-up is bonded rather than fastened, so the constraint costs you nothing. It does matter if someone proposes mechanically fixing an underlayment down, which is a good reason to read a bid carefully in Katy, Cypress or Fulshear.
