Reinstalling shower pan

[modrob]

2002 Tiffin Allegro gas, no slides, about 31 foot length…
I had to remove the shower to repair some leaks and damage from the skylight. The shower pan is positioned on top of a 3/4” piece of plywood, with about 2x6 frame underneath. HOW in the world is one supposed to get access to hook up drain and tighten? The platform has a hole cut out for the drain but it’s not much bigger than the drain itself—nowhere near big enough to get my hand down into it. The platform frame is glued and stapled so it doesn’t offer a way to hinge out of the way—not even sure getting a hand back in that way could be done…

Not sure how you coach is laid out, but in my Newmar there are two ways to access the shower drain. The bathroom floor is raise up one step and Newmar has installed a false vent on the vertical part of the raised area such that I can pull the vent cover off and get access to the p-trap. Additionally, on the underside of the coach, Newmar has a cutout directly under the p-trap and an aluminum plate covering the cut out. So if needed, I could remove the cover to access that plumbing. Perhaps you have one or both of these accesses. Can you make a cutout and put a cover over it when your done?
