When it comes to tiling a shower, one of the most common questions is whether or not you can tile over drywall. The short answer is yes, you can tile over drywall in a shower. However, it’s important to keep in mind that drywall isn’t a suitable backing material for tile showers. Even if your bathroom has moisture-resistant drywall, it won’t provide the requisite moisture resistance.
To ensure that your tile shower lasts for years to come, it’s important to use a suitable backing material. While drywall can be used as a temporary solution, it’s best to use cement board or another moisture-resistant material for a more permanent solution. By using the right backing material, you can prevent water damage and ensure that your tile shower looks great for years to come.
If you’re planning to tile a shower and aren’t sure where to start, it’s important to do your research and make sure you’re using the right materials. While tiling over drywall is possible, it’s not always the best solution. By using a suitable backing material, you can ensure that your tile shower is both functional and beautiful.
Understanding Drywall and Its Suitability in Showers

Drywall is a popular material used to cover walls and ceilings in homes and buildings. It is made of gypsum plaster that is sandwiched between two layers of paper. Drywall is easy to install, affordable, and can be painted or wallpapered to match any decor. However, when it comes to showers and other high-moisture areas, drywall is not the best option.
Drywall is not waterproof, and it can easily become damaged and moldy when exposed to moisture. Water can seep through the paper and into the gypsum core, causing the drywall to swell, crumble, and eventually deteriorate. This can lead to a host of problems, including mold growth, water damage, and structural issues.
In addition to its lack of water resistance, drywall is also not very durable. It is prone to dents, scratches, and other types of damage, which can be unsightly and difficult to repair. This is especially true in areas where there is a lot of foot traffic or where objects are likely to be bumped or knocked into the walls.
Overall, while drywall may be a suitable option for some areas of the home, it is not recommended for use in showers or other high-moisture areas. Instead, it is best to use a waterproof material, such as cement backer board, to create a suitable surface for tiling. This will help to ensure that your shower remains in good condition for years to come.
Process of Tiling Over Drywall in Showers

Tiling over drywall in showers is possible, but it requires additional steps to ensure proper adhesion and prevent moisture damage. In this section, I will outline the process of tiling over drywall in showers, including preparation, application, and finishing touches.
Preparation
Before tiling over drywall in a shower, it is important to prepare the surface properly. Here are the steps to follow:
- Clean the drywall thoroughly to remove any dirt, dust, or debris.
- Apply a waterproofing membrane directly over the drywall to provide moisture resistance. This can be done using a paint-on membrane or a sheet membrane.
- Allow the membrane to dry completely before proceeding with tiling.
Application
Once the surface is properly prepared, it is time to apply the tiles. Here are the steps to follow:
- Measure and mark the center of the wall to ensure that the tiles are evenly spaced.
- Apply a layer of thin-set mortar to a small section of the wall using a notched trowel.
- Press the tiles into the mortar, using tile spacers to ensure even spacing between the tiles.
- Continue applying mortar and laying tiles in small sections until the entire wall is covered.
- Allow the mortar to dry completely before proceeding.
Finishing Touches
After the tiles are applied, it is time to add the finishing touches. Here are the steps to follow:
- Remove the tile spacers and fill in the gaps between the tiles with grout.
- Use a grout float to apply the grout, making sure to fill in all the gaps.
- Wipe away any excess grout with a damp sponge.
- Allow the grout to dry completely before using the shower.
In conclusion, tiling over drywall in showers is possible, but it requires additional steps to ensure proper adhesion and prevent moisture damage. By following the steps outlined above, you can successfully tile over drywall in your shower.
Potential Risks and Challenges
Moisture and Mold Issues
Tiling over drywall in a shower can lead to moisture and mold issues. Drywall is not waterproof, and it can absorb moisture from the shower, leading to mold growth. This can cause health problems for individuals who are sensitive to mold. Moreover, pests such as termites and carpenter ants thrive in moist environments, and moisture seeping into the drywall can attract them.
To prevent moisture and mold issues, it is advisable to use cement backer board or a waterproof material instead of drywall. These materials are better suited for creating a suitable surface for tiling in wet areas. Cement backer board is resistant to moisture and mold, and it provides a solid base for tiles.
Longevity and Durability Concerns
Tiling over drywall in a shower can also lead to longevity and durability concerns. Drywall is not as strong as cement backer board, and it can crack or disintegrate over time. This can cause the tiles to loosen or fall off, leading to expensive repairs.
Using cement backer board or a waterproof material can help ensure the longevity and durability of your shower. These materials are strong and durable, and they provide a solid base for tiles. They are also resistant to moisture and mold, which can help prolong the life of your shower.
In conclusion, tiling over drywall in a shower can lead to potential risks and challenges, such as moisture and mold issues, and longevity and durability concerns. To ensure a safe and long-lasting shower, it is advisable to use cement backer board or a waterproof material instead of drywall.
Alternative Solutions

When it comes to tiling over drywall in a shower, there are alternative solutions that can be considered. Here are two options to consider:
Use of Cement Board
One alternative to tiling over drywall in a shower is to use cement board. Cement board is a type of backer board that is specifically designed for use in wet areas, such as showers. It is made from cement and reinforced with fiberglass mesh, making it resistant to moisture and mold.
Using cement board as a substrate for your shower tiles can provide a more secure and durable surface than drywall. However, it is important to note that cement board installation requires a bit more work and expertise than simply tiling over drywall. It is recommended to consult with a professional contractor if you are considering this option.
Waterproofing Membranes
Another alternative to tiling over drywall in a shower is to use a waterproofing membrane. A waterproofing membrane is a layer of material that is applied to the shower walls before tiling. It creates a barrier between the tiles and the drywall, preventing moisture from seeping through.
There are several types of waterproofing membranes available, including sheet membranes and liquid-applied membranes. Sheet membranes are typically made from materials like PVC or rubber, while liquid-applied membranes are applied in a liquid form and then allowed to dry and harden.
Using a waterproofing membrane can provide added protection against moisture and help extend the life of your shower tiles. However, it is important to follow the manufacturer’s instructions carefully when installing a waterproofing membrane to ensure that it is applied correctly and effectively.
