How to Install a Wet Room on a Concrete Floor?

Installing a wet room on a concrete floor can be a great way to enhance your bathroom space, creating a sleek and functional waterproof bathroom. With the right materials and techniques, you can transform a concrete floor into a stylish wet room that’s easy to maintain and adds value to your home.

Why Install a Wet Room on Concrete Floors?

Concrete floors are durable and versatile, making them an ideal base for wet room installation. Wet rooms are fully waterproofed spaces where the shower area is level with the rest of the floor, allowing for a seamless and modern look. They are especially popular for ground floor slabs or ground floors in homes.

A wet room on a concrete floor has several benefits:

  • Space-saving: Perfect for smaller bathrooms, as there’s no need for a separate shower tray or enclosure.
  • Easy to clean: A single, level floor is simpler to clean.
  • Waterproof: Proper wet room installation ensures that water doesn’t leak into the surrounding floors or walls.

Materials and Tools Needed

Here’s a list of materials and tools you’ll need to install a wet room on a concrete floor:

Materials

  • Waterproof membrane: To create a watertight layer under the tiles.
  • Drainage system: This could be a linear drain or point drain.
  • Self-leveling compound: For leveling the concrete floor surface.
  • Tiles: Non-slip tiles are best for wet rooms.
  • Tile adhesive and grout: For securing tiles to the floor.
  • Primer: Helps the waterproof membrane bond to the concrete floor.

Tools

  • Trowel: For applying the waterproof membrane and tile adhesive.
  • Drill and saw: For installing the drainage system.
  • Spirit level: To ensure even flooring.
  • Bucket and mixing paddle: For mixing the self-leveling compound and tile adhesive.

Step-by-Step Guide to Installing a Wet Room on Concrete Floor

Prepare the Concrete Floor

To start, clear the space where you plan to install the wet room. Ensure the concrete floor is clean, dry, and free from dust or debris.

  • Tip: Use a broom or vacuum to remove any loose particles.

Dig the Concrete to Set a Drain

The next step is to create space for the drain. Using a saw or drill, carefully dig the concrete to make room for your chosen drainage system.

  • Tip: Make sure the drain is positioned at the lowest point of the floor to help water flow easily.

Install the Drainage System

Once you’ve dug out the area, it’s time to install the drainage system. Position the drain in place, following the manufacturer’s instructions, and ensure it connects properly to your home’s plumbing.

  • Tip: Use a spirit level to confirm the drain is level with the flooring around it.

Apply a Primer to the Concrete Floor

Before laying down the waterproof membrane, apply a primer to the concrete floor. This helps the membrane adhere better and prevents any moisture from rising up through the concrete slab.

Install the Waterproof Membrane

The waterproof membrane is essential in wet room installation as it keeps water from seeping into the concrete floor. Carefully apply the membrane across the entire area, extending it up the walls by at least a few inches to create a complete seal.

  • Tip: Be sure to overlap any membrane sheets and seal them to prevent leaks.

Level the Concrete Floor with a Self-Leveling Compound

After the waterproof membrane is in place, pour a self-leveling compound over the concrete floor to create a smooth, even surface. This will ensure that the tiles lay flat and the water flows toward the drain.

  • Tip: Use a trowel to spread the compound evenly, making sure to remove any air bubbles.

Lay the Tiles

Once the floor is dry, you can start tiling. Apply tile adhesive and place non-slip tiles across the floor, beginning at the edge and working toward the drain.

  • Tip: Use a tile cutter for precise edges around the drain and walls.

Grout and Seal the Tiles

After the tiles have been laid, apply grout between each tile to finish the look. Ensure all gaps are filled and wipe away any excess grout.

  • Tip: For added protection, use a waterproof sealant around the edges of the tiles to prevent any water from seeping through.

Tips for Maintaining a Concrete Floor Wet Room

  • Keep the drain clean: Regularly clear the drain to prevent clogs.
  • Use a squeegee: After each shower, use a squeegee to remove excess water from the floor.
  • Check seals: Periodically inspect the waterproof membrane and grout to ensure they remain intact.

Benefits of a Wet Room on a Concrete Floor

Installing a wet room on concrete floors comes with multiple benefits, including:

  • Durability: Concrete floors are long-lasting and resistant to wear.
  • Easy Maintenance: Wet rooms are generally easier to clean due to the single-level floor design.
  • Modern Look: Wet rooms create a sleek, open look that adds style to any bathroom space.

Conclusion

Installing a wet room on a concrete floor is a rewarding project that can transform your bathroom into a sleek, easy-to-maintain space. With the right materials and careful installation, your wet room can provide years of comfort and style, making it a practical and stylish addition to any home.
