We handle wet room bathroom build across 77494 in Katy, roughly 10 miles from our Energy Corridor base.

Wet rooms fail in a small number of predictable ways, and all of them trace back to the floor. Water that does not reach the drain, water that leaves the room, a membrane that stops short of where the water actually goes, a floor that looks flat because it is flat, and a fan that cannot dry any of it. Because the whole floor is the shower, there is no curb to catch a mistake, which is exactly why the detailing has to be right the first time. Here is what goes wrong and what prevents each one.

What the work involves

Insufficient fall. If the floor does not slope enough toward the drain, water pools and never fully dries. Prevention is a pre-sloped tray or a properly graded mortar bed, checked with a straightedge and a bucket of water before waterproofing, and slope maintained through the tile rather than flattened by the setting bed.

Membrane that stops too soon. In a wet room the waterproofing must run the full floor and up the walls beyond the spray zone, with the drain integrated into the membrane. A membrane sized for a conventional shower is the most common serious mistake.

Water escaping the room. Without a curb, the doorway is the weak point. Prevention is a fall that runs away from the door, a threshold detail, and containment with a glass panel.

Undersized drainage. A large linear drain looks impressive but must actually be connected to a line that can carry the flow.

Slippery tile. Prevention is a tile with real wet grip, not a polished surface chosen from a showroom photograph.

What drives the cost

Prevention concentrates in the floor: pre-sloped substrate or a properly built mortar bed, full-floor bonded waterproofing, crack isolation, and a flood test. Those items are where a wet room bid legitimately exceeds a standard shower bid, and they are also the easiest to leave out quietly.

Drain relocation and slab type sit alongside them, with tendon location required before cutting a post-tension slab.

Then containment, because a glass panel is a real line item, and tile choice, because textured and smaller-format tile costs more to set on a sloped plane.

Ventilation upgrades are minor money with major consequences. Heated floors, benches and second outlets are elective and priced accordingly.

Building for Gulf Coast conditions

Local conditions sharpen two of those. The first is drying. At Houston dew points, a wet room with a builder-grade fan will still be damp hours later, and permanently damp grout grows what you would expect. Ventilation is sized for the room and the wet area, ducted outside in insulated duct with a working damper, and ideally on a timer so it runs after you leave.

The second is slab movement. A wet room is a large continuous tiled plane bonded to a slab that moves seasonally on expansive clay. Without crack isolation and planned movement joints, that plane will crack somewhere, and in a wet room the crack is directly over waterproofing you cannot inspect. The membrane should be the thing holding water out, not the tile, but a cracked floor is still a repair nobody wants.

Hard water adds the cosmetic failure: mineral film over a large tiled area and a glass panel. Tile selection and coated glass reduce it.

Working 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.

How we work

We resolve the floor assembly and drain position first, then the fall and containment on paper.

Demolition, drain work, rough-in, inspections where required. Then the slope is built and checked with a straightedge and water before anything covers it. Full-floor waterproofing goes on, corners and drain integrated, and the room is flood tested overnight.

Tile is set with the slope maintained, movement joints placed at the perimeter and changes of plane, and corners sealed rather than grouted. Glass is templated after tile.

Ventilation is commissioned by measuring that it actually moves air, not by listening to it run.

Common questions

Will water get out into the hallway?

Not if the floor falls away from the door, the threshold is detailed, and there is containment near the shower head. Problems arise when a wet room is built with a level floor and a drain, no panel, and a doorway on the low side. Those three together push water toward the hall. Each one is a design decision made before construction.

Is a linear drain better than a centre drain?

It allows a single-direction slope, which suits large-format tile and looks cleaner, and it is common in wet rooms for that reason. It is not automatically better. What matters more is that the drain is sized and connected to a line that can carry the flow, that it is integrated into the waterproofing membrane correctly, and that the floor actually falls to it.

Why does water pool on my wet room floor?

Almost always insufficient or uneven fall. It can come from a mortar bed that was floated flat in places, a slope that was correct in the substrate and then flattened by the tile setting bed, or a drain set slightly high relative to the surrounding floor. It is checkable with a level and a small amount of water, and the fix generally means taking up tile.
