Installing Specialty Recreation RV Shower Pan

Question

Question:

I have studied the photos, listened to the video and read the install instructions. To look at the design, it would appear the wall panels would go inside of the lip so that water all stays in the pan. But the instructions say to set the walls and then screw through the lip into the wall. If you so that it would be impossible to get a good seal as water running down the shower walls will go in any tiny space between the wall and the lip. Am I missing something on the installation?

Hi Bob; the walls referenced in the instructions are the literal walls, different from a surround/panels like # SR75RR which would be installed after you get the Specialty Recreation RV Shower Pan # SR23RR in place.

Regardless, you need to use ABS compatible, silicone based sealer or caulk sealer once it is in place to seal everything up and keep water from getting through any of those spaces you're referring to. I would expect to see caulk in your existing shower at the connecting edges unless you have something that is one solid piece.

We don't have any good videos on shower installation but there are quite a few out there on RV channels so I would check them out. A lot of the time those real world experiences result in better installation methods, or at least a better order of operations for the steps, compared to the instructions.

Hey Bob, how did things go with sealing the shower pan and wall panels after using the silicone-based caulk? Your update could make it easier for others working through the same installation steps.

Robin, Thanks for checking back. I haven't done it yet but your explanation helped me figure it out. The "base walls" will be 1/2" plywood and they will go outside the pan and be secured to the pan with screws through the pan lip into the plywood, as the install instructions state. Then we will adhere a layer of vinyl sheet floor material to the plywood and it will come inside the pan covering the lip. All water will then go down into the main section of the pan and there is no seam that could leak since the water flow is always in a downward position at the lip. In fact, there would be no need for any type of sealant at the seam between the vinyl finish wall covering and the pan since it laps inside a sufficient amount.
