Creating a wet room typically requires between two and four weeks from start to completion. The timeline varies based on your bathroom's current condition, the complexity of waterproofing needed, and whether structural modifications are necessary. Waterproofing applications need proper curing time between layers, and tile installation must be done methodically to maintain drainage slopes. Coordinating multiple specialists can also extend the timeline, especially in regions where qualified contractors are in high demand.

The primary distinction lies in the extent of waterproofing and the integration with the bathroom space. Wet rooms feature comprehensive waterproofing throughout the entire bathroom, with floor-to-ceiling treatment and drainage systems built into the floor structure itself. Walk-in showers, while barrier-free, still maintain a defined shower area with waterproofing limited to that zone. This fundamental difference explains why wet rooms typically cost more to install but create a more seamless, open bathroom experience.

The ideal flooring for wet rooms combines water resistance, slip resistance, and visual appeal. Porcelain and ceramic tiles remain popular choices, professionally installed at $5 to $45 per square foot depending on quality and design complexity. Natural stone provides luxury appeal but requires proper sealing and more maintenance. Specialized vinyl flooring systems designed specifically for wet environments offer a more budget-friendly alternative, though they typically don't last as long as properly installed tile. All flooring must be installed over a properly prepared waterproof membrane system.

Small bathrooms can be excellent candidates for wet room conversions when designed thoughtfully. By eliminating bulky shower enclosures, wet rooms can make compact spaces feel more open and accessible. However, smaller areas require careful planning to control water spray—often through strategically placed glass panels or shower curtains. Proper ventilation becomes even more critical in smaller spaces to prevent excessive humidity. With appropriate design considerations, even bathrooms as small as 30-40 square feet can be transformed into functional, stylish wet rooms.
