Kerdi Shower Pan With Cement Board Walls
The topic of using a Kerdi shower pan with cement board walls is a common question among DIYers and homeowners who are renovating their bathrooms. The Kerdi shower pan is a popular choice for creating a waterproof shower base, and when paired with cement board walls, it can provide a durable and reliable watertight enclosure.
Proper waterproofing is essential in a shower because it prevents water from penetrating the walls and floor and causing damage. If a shower is not properly waterproofed, water can seep into the walls and floor, causing damage to the structure of the building and potentially leading to mold growth.
Waterproofing the shower also helps to prevent leaks and moisture damage in adjacent rooms, which can be costly to repair. Using a high-quality waterproofing system like the Kerdi shower pan can help ensure that the shower is properly sealed and protected from water damage.
Benefits of the Kerdi system
The Kerdi shower pan is a popular choice for waterproofing showers because it is easy to install and creates a reliable waterproof barrier. The pan is made of a polystyrene core covered with a layer of reinforced, waterproof membrane material. This design allows it to be easily cut and molded to fit the shape of the shower and create a watertight seal.
In addition to the shower pan, the Kerdi system also includes a waterproofing membrane and bands that are used to seal the seams between the pan and the walls. The membrane is a thin, flexible material that is applied over the cement board walls and adhered to the shower pan using the accompanying bands. This creates a continuous waterproof barrier that prevents water from penetrating the walls or the shower pan.
One of the key benefits of the Kerdi system is that it is designed to work together as a complete waterproofing solution. Using the pan, membrane, and bands together ensures that the shower is properly sealed and protected from water damage. This is important because even small leaks can cause significant damage over time, and can lead to mold and other health hazards.
Another advantage of the Kerdi system is its durability. The pan and membrane are made of high-quality materials that are resistant to cracking, peeling, and other types of wear and tear. This means that they will continue to provide effective waterproofing for many years, even with regular use.
Overall, the Kerdi shower pan and accompanying membrane and bands offer a reliable and long-lasting solution for waterproofing a shower. Using the entire system together ensures a properly sealed and protected shower that will remain watertight for years to come.

Installing a Kerdi shower pan with cement board walls
Installing a Kerdi shower pan with cement board walls requires careful preparation and attention to detail. The following steps outline the process for installing a Kerdi shower pan and accompanying membrane and bands on cement board walls:
Preparing the subfloor
- Before beginning the installation, the subfloor must be properly prepared to ensure that the shower pan sits level and is supported properly. This may involve reinforcing the subfloor or adding additional layers of material, depending on the condition of the existing subfloor.
- It is important to check the subfloor for level and to make any necessary adjustments to ensure that the shower pan will sit evenly.
Attaching the cement board
- Once the subfloor is prepared, the next step is to attach the cement board to the walls. This is typically done using cement board screws or nails, and the seams between the sheets of cement board should be sealed with thin-set mortar and fiberglass mesh tape.
- It is important to make sure that the cement board is attached securely to the walls and that the seams are sealed properly to prevent water from penetrating behind the cement board.
Installing the Kerdi shower pan
- The Kerdi shower pan is installed by cutting it to fit the dimensions of the shower and attaching it to the subfloor using thin-set mortar. The pan should be positioned so that it slopes slightly towards the drain, and the edges should be sealed with this set to create a watertight seal.
- It is important to follow the manufacturer’s instructions for installing the shower pan, as different models may have different requirements.
Installing the Kerdi membrane and bands
- Once the shower pan is in place, the next step is to install the Kerdi membrane and bands on the walls. The membrane is a thin, flexible material that is applied over the cement board walls and adhered to the shower pan using the accompanying bands. This creates a continuous waterproof barrier that prevents water from penetrating the walls or the shower pan.
Importance of using the entire Schluter system
It is important to use the entire Schluter system for proper waterproofing because each component of the system is designed to work together to create a watertight seal. The Schluter shower pan and membrane, along with the band and other accessories, are all specifically engineered to work together to create a durable and reliable waterproofing system.
Using the entire system ensures that all the components are compatible and that the installation will be effective at preventing leaks and moisture damage. It is not recommended to mix and match components from different manufacturers or systems, as this can compromise the effectiveness of the waterproofing and increase the risk of leaks.
Tips for a Successful Installation
- Plan and prepare before starting the installation. This includes carefully reading the manufacturer’s instructions and gathering all the necessary tools and materials.
- Make sure the subfloor and walls are in good condition and properly prepared to receive the shower pan and tile. This may include reinforcing the subfloor, repairing any damage, and ensuring that the walls are flat and level.
- Use the correct adhesive and grout to install the shower pan and tile. Follow the manufacturer’s recommendations for the best results and to ensure a waterproof seal.
- Take your time and pay attention to detail. It’s important to carefully follow the manufacturer’s instructions and make sure all joints are properly sealed and all surfaces are properly waterproofed.
- Test the shower for leaks before using it. This can be done by filling the shower with water and checking for any leaks or moisture accumulation. If any leaks are found, they should be repaired before using the shower.
