A wet room without a properly engineered floor isn't a design choice. It's a flood. Removing the curb doesn't make a wet room. It makes a shower that floods the bathroom — and we've seen the damage firsthand in Riverview homes.
Riverview homeowners requesting wet rooms in master bath renovations are asking for the right thing — a continuous tiled floor through the entire bathroom, a shower zone defined by the drain and the fixture rather than a curb or glass enclosure, and the spatial openness that a traditional shower surround removes. The problem is that almost no tile contractor in this market has built one correctly, and most attempts we've been consulted on afterward were standard shower builds with the curb removed and nothing else changed.
We've been consulted on wet room retrofits in Riverview homes where a previous contractor removed the curb, reset the tile, and called it a wet room. No slope correction. No full floor waterproofing. No DCOF-rated tile. The drain worked. The floor didn't — water pooled at the vanity wall and found its way into the subfloor within months. A wet room is not a curb-removal job. The entire bathroom floor has to be treated as a wet area: full waterproofing membrane across the complete floor surface, slope established from the room perimeter toward the drain, and DCOF-rated tile selected for the wet zone. The slope system has to cover the full floor, not just the shower footprint, and the membrane has to do the same.
Murati plans wet rooms from the subfloor: drain location, slope geometry across the full floor, membrane system selection, substrate build-up height relative to the adjacent room's floor level, and tile format selected to meet both the design intent and the wet area DCOF requirement. Every decision on paper before a trowel touches the floor.
The most common wet room installation failure is treating the project as a standard shower build with the curb removed. That approach fails in two predictable ways. First, the waterproofing: a standard shower membrane covers only the shower footprint. A wet room membrane has to cover the entire bathroom floor and extend up the walls to the correct height — typically 6 inches above finished floor level — to contain water that flows outside the shower zone. A shower-footprint-only membrane leaves the rest of the floor completely unprotected. We've seen the result in Riverview retrofits: water following the tile grout toward the vanity wall and into the subfloor in months.
Second, the slope: a standard shower pan is sloped from four sides toward a center drain within a confined footprint. A wet room floor is sloped from the room perimeter toward a drain positioned to serve the full floor area. That slope has to be continuous across the whole floor surface, which means the mortar bed is not a shower pan — it's a full-room subsystem. If the slope calculation is wrong, water pools away from the drain in the areas of the floor that aren't in the shower zone. In a 100-square-foot bathroom, that's a significant standing water problem that presents itself the first morning someone showers.
Drain sizing also matters differently in a wet room. In a standard shower, the drain handles water from a confined shower area. In a wet room, it handles incidental water from the entire bathroom floor — steam condensation, splashing around a freestanding tub, overflow from a dropped towel. The drain has to be sized and positioned for the full room's water load. We work through drain selection, slope geometry, and membrane coverage at the planning stage — not after the mortar is set and the geometry is locked.
Murati plans wet room installations from drain location and slope geometry through tile selection and DCOF verification — all resolved before a single cut is made.
