Should You Tank A Bathroom?

Yes, it is generally recommended to waterproof or "tank" a bathroom before tiling. Waterproofing is a crucial step in the tile installation process, especially in areas prone to moisture, such as bathrooms and showers. Waterproofing helps prevent water from seeping through the walls and floors, which can lead to damage over time, including mold growth and structural issues.

Here are some steps to consider when waterproofing a bathroom before tiling:

1. Surface Preparation: Ensure that the surface to be tiled is clean, dry, and free from any debris or contaminants. Repair any cracks or imperfections in the substrate.

2. Choose the Right Waterproofing Material: There are various waterproofing materials available, including waterproof membranes, liquid waterproofing coatings, and cementitious waterproofing products. The choice of material will depend on your specific project and local building codes.

3. Apply Waterproofing Material: Follow the manufacturer's instructions for applying the chosen waterproofing material. Typically, this involves applying multiple coats to ensure complete coverage and sealing all seams, corners, and penetrations (such as pipes and drains).

4. Allow for Proper Drying Time: Ensure that the waterproofing material has sufficient time to dry and cure before proceeding with tile installation. Drying times can vary depending on the product used, so refer to the manufacturer's guidelines.

5. Test for Leaks: Before tiling, it's a good idea to perform a water test to check for any potential leaks. Fill the shower or bathtub with water and let it sit for a period to see if any water penetrates through the waterproofing.

6. Tile Installation: Once you are confident that the waterproofing is effective, you can proceed with the tile installation. Use a suitable adhesive or thin-set mortar for your tiles and grout them properly.

Proper waterproofing is essential to protect the underlying structure and prevent water damage over time. Be sure to follow local building codes and industry best practices when waterproofing and tiling a bathroom to ensure a durable and long-lasting installation. It's also a good idea to consult with a professional if you are unsure about the process or materials to use.
