• 1Hot Mop Layers

    Hot Mop Shower Pans must be constructed of 4 layers of hot tar and 3 layers of 15lb perforated felt. The hot mop is sandwiched in Layers using hot mop and #15 perforated felt paper. The installer will custom cut each shower pan, size specific to your unique size and shape shower.


    Shower pans before hot mopping must be pre-pitched ¼” slope per foot using mortar mix cement. This takes a trained eye and many years to perfect which allows water that penetrates through the tile to flow over the hot mop and into the weep holes. We receive many compliments from our contractors about our hot mopping pre-slopes, so don’t try this yourself. Leave it to us, as it is always included in our price.

  • 3Hot Mop Drain

    Use a two piece “Hot Mop” shower drain with a water test stopper in place. Cast Iron or Plastic are both acceptable drains to use for Hot Mop Showers. Remember to set the drain flush or resting on the subfloor as shown in the picture to the left. If you are using an existing shower drain be sure to inspect and clean the hot mop from between the two flanges..


    2×10 blocking should be used against the wall studs for the hot mop paper support, this is most common. If there are pipes or any obstructions preventing 2X10’s, other sheeting such as a thin gauge metal or 1/2″ plywood will also be acceptable. Benches and seats should be built strong and then covered with plywood so we can glue our Hot Mop and Felt paper to achieve best results. Remember we will Hot Mop up the face of the bench, then onto the flat part where you sit, and back up the wall 6″ so be sure to add some blocking above the bench also. The curb is three 2×4’s stacked minimum as in the picture to the left, unless your shower is recessed.
