Anyway, I would have liked to just buy a premade fiberglass shower but my drain is offcenter and buried in concrete (basement floor shower). I have a few questions:
1. Is it okay to remove any of the rotted wood, reinforce with sandwiched new wood (pressure treated I was thinking)? I'd rather now remove all the plywood and redo all the framing. It appears to be very sturdy.
2. Are there any other options to redoing the shower pan with tile as before since the drain is off center? I know I can jackhammer the floor but am not really interested in that option. I thought about building up the floor and getting some kind of pipe to relocate it but little room to build up. I know custom pans are available but very pricey. This is a guest bathroom so I'm really thinking least cost, lowest maintenance.
3. For the walls, I'd prefer not to do tile again just because of the work and upkeep. Someone recommended cultured marble but I would guess the answer to #2 would affect this option. That is, how would it look to have cultured marble walls and a tile basin?
Any other suggestions would be appreciated. I also looked at Tirazzo solutions but they also seem cost prohibitive.
