Hi all, I'm new to the forum, and had a question about shower drains. My customer has chosen to replace his tub, and install a fiberglass shower receptor. The tub had a 1 1/2" trap and trap arm, which ties into the 2" drain line. I know that a shower is supposed to have a 2" drain, but it's simply not an option. Even if I could get access, which would involve wrecking the ceiling of the recently remodeled powder room below, there isn't any way to tap into the drain line. The bathroom is on the second floor, with another bathroom behind it, and a laundry room is on the side wall. There are drain and vent pipe connections for 2 tubs, 2 lavatories, and the laundry standpipe. The tees off of the drain pipe are spaced so close together, that even is I could cut out the 2 x 2 x 1 1/2 tee, there wouldn't be enough pipe next to the adjacent tees to solder on a new one. I know they are not going to want me to trash the powder room below, and the wet wall in the newly remodeled kitchen to cut out everything and start over. I have informed them of the possible risks involved with using 1 1/2" drain pipe for a shower, and that it was against code. They are willing to accept the risk, and so am I. I live in a 110 year old house, with 1 1/2" cast iron drain in my shower, and never had any problem. My question is, what to do about the shower drain. Every drain I've seen with a 4 1/4" flange is designed to be connected to 2" PVC, and I need to connect to 1 1/2" copper. I've been a remodeling contractor for 25 years, so I'm not some naive homeowner who doesn't know what they're doing. I've simply never run into this situation before. Please, no condescending remarks, or lectures on needing to trash their house in order to "do it right". I'm all for doing it right when at all possible, and usually go beyond code to know that what I've built will still be there in 100 years, but I know that my customer isn't going to spend 30 grand to remodel a 5 x 7 bathroom!! Any ideas regarding the shower drain?
