How to solidify shower floor?
We have an Outback 325BH which has a corner shower. The shower floor has always been fairly soft, and VERY soft around the drain. I removed the access panel to see what is going on and I see why. The shower pan basically sits on a wood platform with a hole cut in the middle for the drain. Problem is the hole in the platform is probably 12-16" diameter so all of that area is not supported. There are 2 additional 2x4 pieces that help support it.
So.. I'm curious if anyone has come up with a way to solidify the shower without removing the whole shower and replacing the platform. Any thoughts?
