How to Install the Shower Pan

Well I am back from a week of vacation spending time with my wife and new son. It was very relaxing. This is the next step in installing a tiled shower stall.

Once I had the solid plywood subfloor screwed down it was time to put the shower pan in. The first step is to connect the drain to the pan. You can follow the directions from the manufacturer but basically you put a bead of 100% silicone caulk on both sides where the drain will seal against the pan. You then place the two halves of the drain on either side of the pan and screw them together. This will allow a flange to tighten against the pan on both sides with the silicone completing the seal.

The next step is to make sure the drain in the shower pan will sit nicely into the waste pipe in your floor. I just placed it in the shower stall and dry-fitted it. Since my shower drain was self-sealing I did not have to worry about any further installation details.

I removed the shower pan, spread a layer of thinset morter with a notched trowel just as if I was laying tile and then set the shower pan into it. The drain fit nicely into the waste pipe as it did when I dry-fitted it. I then used the wrench provided with the drain to tighten its gasket around the waste pipe, completing the seal. I walked around on the shower pan to set it in the morter and then left it to set for a day before moving on. Here it is installed.

This is probably one of the most critical parts of putting in a new shower. When you think of the volume of water that has to be processed through this pan and drain on a daily basis and what can happen if there is a leak it is scary. I myself turned the water on accidentally before hooking the drain up and had water pouring from the ceiling on the first floor. It could have been a real disaster.

If you have any reservation about this step I would suggest ordering the new video by Randy Davis. I have found them to be very high quality and you get a 2 month money back guarantee. Check it out HERE.

Next we will talk about moving to the walls.
