- Waterproofing: A critical layer that adds $1,000 to $2,500, depending on the method and materials.
- Labor: Skilled installers charge $60 to $100 per hour, often including tile, slope work, and sealing.
- Permits and inspection: Around $200 to $500, depending on your area.
- Disposal and prep: Removing old tubs, tile, and fixtures can add $500 to $1,000.
Budget an extra 10 to 15 percent for surprises in older homes. Hidden leaks or structural fixes often appear once demolition begins.
DIY vs Pro
Some steps are safe for confident DIYers, but others must be handled by licensed pros.
What You Can Do
- Demolition: Remove old tile and fixtures, but wear gloves, goggles, and a respirator.
- Design layout: Measure drainage slope and choose tile size to avoid awkward cuts.
- Finishing touches: Install accessories, mirrors, and lighting after inspection.
When to Hire a Pro
- Waterproofing membrane: Requires precise overlap and sealing. Mistakes cause leaks.
- Drain and slope installation: Must meet local plumbing code.
- Glass partition and tile setting: Heavy materials demand exact alignment.
- Electrical or heated floor systems: Always need licensed work for warranty and safety.

Why Wet Rooms Win Over Traditional Baths
Homeowners are prioritizing flexibility, accessibility, and easy upkeep. The wet room design fits these needs perfectly.
Open Layout
Without a tub or raised shower base, the floor runs seamlessly wall to wall. This makes small bathrooms feel larger and brighter. Wheelchair access becomes easier, and cleaning takes less time.
Water Control
Modern membranes and linear drains handle splashes efficiently. When installed correctly, water evaporates quickly without pooling. No step or lip means fewer tripping hazards.
Resale Appeal
Buyers now view a curbless shower as a sign of a high-end remodel. Realtors report wet rooms stay cleaner and require less ongoing maintenance than tub setups, which helps resale value.
Easy Maintenance
Fewer joints and barriers mean fewer grime traps. A daily wipe-down keeps surfaces spotless. Annual regrouting is simpler since most tiles are uniform and accessible.
Long-Term Accessibility
Aging homeowners value no-step entries and slip-resistant surfaces. A wet room can serve all ages without modification, saving future renovation costs.
Maintenance and Warranties
A well-sealed wet room lasts decades, but only with consistent care.
- Inspect grout lines twice a year. Reseal as needed with a penetrating sealer.
- Clear the drain monthly to prevent buildup that slows water flow.
- Check sealant edges around glass panels and fixtures. Replace if cracking appears.
- Use mild cleaners. Acid-based products can damage grout and stone.
- Renew membrane warranty by keeping records of pro service or inspection.
Waterproofing systems often carry 10-year warranties when installed by certified professionals. Keep receipts and documentation for any future claim.
Safety and Code Checks
Before starting, confirm that your home subfloor and plumbing can handle the new layout.
- Turn off water supply before demolition.
- Check for hidden electrical lines behind tile walls.
- Confirm floor slope is at least 2 percent toward the drain.
- Use slip-resistant tile with a texture rating suitable for wet areas.
- Get required permits for plumbing changes and electrical upgrades.
Hire a licensed pro when moving drains, replacing joists, or connecting radiant heat mats. These steps must meet code and inspection standards.
Market Outlook
Wet room demand keeps growing. Designers expect curbless showers to remain a dominant bathroom feature. Material suppliers now offer more tile formats and prefabricated drain kits, cutting installation time and risk.
Supply chain delays have eased, but custom glass and imported tile still carry long waits. Plan early if you want unique finishes or large-format stone.
Your Next Steps
- Measure your space and sketch a layout that includes slope direction and drain placement.
- Request two or three quotes from licensed installers to compare waterproofing systems and warranties.
- Select tile and fixtures that balance price, traction, and style.
- Plan the schedule around material delivery and inspection windows.
- Keep 15 percent of the budget as a contingency for structure or plumbing surprises.
Wet rooms are not just a design trend. They are a functional, low-maintenance way to future-proof your bathroom.
