Step-by-Step Guide to Building a Custom Shower Pan 

Building a custom shower pan on a concrete floor involves several steps, and the first is preparing the subfloor. Once the subfloor is ready, installing the shower walls is next. Then, the layer of the shower pan should be built using a cement board, followed by the first layer of mortar. The installed shower must be positioned at the centre of the shower stall, and a cement board should be installed around the shower area. To ensure the shower is properly constructed, a layer of mortar and tile should be installed to create a waterproof shower enclosure.

The perimeter of the shower must be properly measured to determine the number of materials needed, typically calculated per foot. The layer over the shower liner should be made of a mixture of Portland cement and sand, and the shower pan can be built using a fibreglass pan. The depth of the pre-slope should allow for the thickness of the top layer of mortar, which is determined by the height of the tile work. Finally, the top edge of the liner should be secured, and the building code will determine the thickness of the layer. It is important to ensure the curb is properly constructed to prevent water leakage, and the distance from the drain to the shower opening should be 12 inches.

How to Properly Adjust the Drain for Your Mortar Shower Pan

To create the perfect shower experience in your bathroom, you must know how to adjust the drain for your mortar shower pan properly. Whether building a new shower or installing a new drain, following the right steps for a waterproof seal is important:

  1. Ensure the shower drain base is securely attached to the concrete shower.
  2. Insert the adjustable drain flange and apply adhesive to the bottom of the shower.
  3. Use a mortar pan to slope towards the drain opening. Be sure to leave about 1 inch of space between the top of the liner and the bottom of the drain so that water can flow through the weep holes.
  4. Create a waterproof membrane by covering the entire shower with a waterproof liner and sealing it at the top of the drain opening.

By following these steps, you can ensure the longevity and beauty of your shower.
