Can You Tile On Plasterboard In A Shower?

Planning a shower remodel? You may wonder if tiling directly on plasterboard is possible. While it's not the most common approach, it can be done with proper preparation and precautions. Here's a comprehensive guide to help you determine if tiling on plasterboard in a shower is feasible and how to do it right.

Is Plasterboard Suitable for Shower Tiling?

Plasterboard, also known as drywall, is a gypsum-based material commonly used for interior walls and ceilings. It is porous and can absorb moisture, making it unsuitable for direct tiling in wet areas like showers. Water penetration can lead to mold growth, tile detachment, and structural damage.

Preparing Plasterboard for Shower Tiling

If you choose to tile on plasterboard in a shower, it's crucial to prepare it thoroughly. This includes:

Installing a Backer Board: A cement-based or waterproof backer board provides a stable and moisture-resistant surface for tiling. It must be properly installed over the plasterboard using thin-set mortar.
Applying a Waterproof Membrane: A liquid-applied membrane or waterproofing paint creates an additional moisture barrier over the backer board. This prevents water from seeping through and damaging the plasterboard.
Sloping the Surface: Ensure the shower floor has a slight slope (minimum 1/4 inch per foot) to direct water towards the drain. This prevents water accumulation and reduces the risk of mold growth.

Choosing the Right Tiles

Not all tiles are suitable for shower installations. Opt for tiles with low water absorption rates (less than 0.5%) and good glaze quality. Ceramic, porcelain, and glass tiles are popular choices due to their durability and moisture resistance.

Tiling Procedure

Once the preparation stage is complete, you can begin tiling the shower. Use a modified thin-set mortar specifically designed for wet areas. Apply the mortar to the back of the tiles and press them firmly into place on the prepared surface.

Grout the joints between the tiles using a waterproof grout. This fills the gaps and creates a watertight seal. Let the grout cure completely before sealing it with a grout sealer to prevent staining and water absorption.

Maintenance and Precautions

To maintain the longevity of your tiled shower on plasterboard, follow these precautions:

Regular Cleaning: Clean the shower regularly using a mild tile cleaner and a soft cloth. Avoid harsh chemicals or abrasive cleaners.
Ventilation: Ensure adequate ventilation in the shower area to reduce moisture buildup. Install a fan or open a window during and after showers.
Monitoring for Leaks: Inspect the shower regularly for any leaks or water damage. Address any issues promptly to prevent further damage.

Conclusion

Tiling on plasterboard in a shower is possible with meticulous preparation and proper materials. By following the steps outlined above, you can create a durable and visually appealing shower that will stand the test of time. Remember to consider the specific requirements of your shower area, choose suitable tiles and materials, and prioritize maintenance for optimal results.
