What is a wet and dry partition?
In many people’s minds, the bathroom is considered a "wet" area due to the frequent exposure to water. After taking a shower, it's common for the entire space to become damp, which can feel uncomfortable and even lead to mold or bacterial growth over time. To prevent this, a wet and dry partition is often used to separate the dry area from the wet area, ensuring they don’t interfere with each other. This design helps reduce water splashing on walls and floors, keeping the space cleaner and more hygienic.
A wet and dry partition typically divides the bathroom into two distinct zones: one for washing and another for showering. By using physical barriers like glass panels, walls, or shower enclosures, it minimizes cross-contamination and keeps the dry area drier. This not only improves comfort but also reduces maintenance and potential damage caused by moisture.
Wet and Dry Shower Room
One of the most popular and effective ways to implement a wet and dry partition is by installing a fully enclosed shower room. It involves selecting a suitable corner in the bathroom, reserving plumbing and electrical connections, and then installing wall tiles before constructing the enclosure. The shower room is usually sealed, equipped with an exhaust fan, and offers good insulation during colder months, helping maintain a dry environment in the dry area.
However, this option requires sufficient space and ceiling height. There are various shapes available—square, rectangular, fan-shaped, or diamond-shaped—but customization options are limited. The choice depends on the size of your bathroom.
Tip: The components of a full shower room, such as glass, hardware, showerheads, pipes, and electrical fixtures, are highly integrated. It’s important to choose reputable brands rather than cheap alternatives to ensure quality and safety.
Glass Partition or Simple Shower Room
If you don’t have the space or budget for a full shower room, a glass partition or simple shower room could be a great alternative. These options typically include an aluminum frame, tempered glass sliding doors, and a base made of stone or a tray. They are custom-made based on your bathroom dimensions and installed after the tiling is complete.
Always make sure that the glass used is tempered, and check for a 3C certification mark (if applicable) and the brand name on the corner. This ensures the product meets safety standards.
Shower Curtain as a Wet-Dry Partition
For small bathrooms where installing a glass partition isn’t feasible, a shower curtain can be a practical and cost-effective solution. It’s easy to install and can be opened during use to prevent water from splashing, and folded away when not in use. This allows you to maintain open space while still separating the wet and dry areas.
Tips:
1. Choose a mildew-resistant shower curtain with a lead wire or hanging rod for better control.
2. To prevent water from pooling on the floor, consider installing a ground-level water barrier made of PVC or stainless steel. Make sure it’s placed carefully to avoid tripping hazards.
3. Use a fixed overhead showerhead to direct water straight down, reducing splash in other directions.
Waterproofing the Wet Area
Proper waterproofing is essential in the bathroom, especially in the wet zone. Experts recommend that the walls around the shower area should be waterproofed up to 1.8 meters high to prevent water penetration and mold growth. In contrast, the dry area only needs 0.3 meters of waterproofing, but the entire floor must be fully sealed.
After the waterproofing work is done, the homeowner should supervise a 24-hour water test. This involves filling the bathroom floor with water and checking for leaks after 24 hours. If any leakage is found, the waterproofing must be redone to avoid future issues.
Slope and Floor Drain for Efficient Drainage
To ensure water drains quickly and doesn’t pool on the floor, the bathroom floor should be sloped slightly toward the drain. A drop of 0.02 to 0.03 meters centered on the floor drain is ideal. This helps water flow smoothly into the drain instead of accumulating on the surface.
The placement of the floor drain is also crucial. It should be positioned at the lowest point of the bathroom. If the drain is located between tiles, the tiler may need to cut and adjust the tiles to create a proper slope. Otherwise, water might collect near the drain, leading to dampness.
Tip: After the installation, fill the floor with water to check if it flows smoothly into the drain and there’s no standing water.
