I ripped out an upstairs one-piece fiberglass shower to put in a new tile shower but I found a vent pipe coming up through the the floor which vents into another piece which vents through the ceiling. I wanted to use one of those pre-builts shower pans like Latricrete Hydro Pan but this pipe is in the way. How would would put in a shower pan and the cement boards on the walls with this thing in the way? I was thinking of building a bench or shelf around it since it's in the corner but wouldn't I be opening myself up to leaks? here are a couple of photos.

I have the frame of my tub deck built, and the top is plywood. I will have a drop in tub, and will have solid surface quartz material for the tub deck. It will be four pieces, so will have four small seams. My question is, and i have not found an answer on the web, is, do i need to put anything on top of the plywood for a solid surface material? If so, what do i need to do? Everything says use cement board for tile, but i cannot find an answer for solid surface.[ATTACH]63065[/ATTACH]
