The item used under the shower pan to create the slope for the drain is called a "shower pan liner" or "shower pan membrane". It is typically made of PVC or CPE (chlorinated polyethylene) and is installed over the subfloor and around the drain to create a waterproof barrier.

The liner is then sloped towards the drain using a combination of techniques, such as sand or mortar beds, pre-sloped foam panels, or adjustable slope systems. The choice of method depends on the specific requirements of the installation and the installer's preference.

Once the liner is in place and sloped properly, the shower pan can be installed on top of it, and the tile or other finish material can be applied. Proper installation of the shower pan liner is crucial for ensuring that water drains properly and does not seep into the subfloor or surrounding areas, causing damage or mold growth.

HydroBlok systems are known for their durability, water resistance, and ease of installation. They can be used for both residential and commercial applications and are suitable for a variety of finishes, including tile, stone, and vinyl.

What is slope requirement in shower pan?

The slope requirement in a shower pan is typically a minimum of 1/4 inch per foot (or 2% slope) towards the drain. This means that the surface of the shower pan must have a gradual slope towards the drain to ensure proper drainage of water and prevent standing water that can lead to mold, mildew, and other issues. The slope requirement may vary depending on the specific building code or manufacturer's recommendations, so it's important to consult the relevant guidelines and instructions before installing a shower pan. Additionally, the slope should be checked and adjusted as necessary during installation to ensure it meets the required specifications.

Put down a layer of felt paper to help prevent moisture from wicking down through to the subfloor. Place a layer of metal lathe over the felt paper. Trowel in a layer of mortar that it has a one quarter inch slope towards the drain. Once the mortar dries, place a layer of felt paper along the walls of the shower stall. Attach cement board with the rough side out along the top half of the walls. Install the shower stall membrane in the bottom of the shower so that it overlaps in the corners, covers the shower curb and is approximately six inches up the side of the walls. Cut out holes for the drain, the drain bolts and the weep holes. Seal the underside of the membrane near the drain with silicone. Nail the membrane that covers the curb only on the outside. Attach the remaining cement board leaving one inch clearance from the bottom. Caulk all seems. Place some pebbles near the weep holes to protect the openings. Trowel in a layer of mortar that has a one quarter inch slope towards the drain. Mortar the curb. Remove the tape from the drain.
