Two 2" drains or One 3" drain
I'm in the process of building a custom 72"x52" shower that will have essentially two full spa like showers each with a rainhead, body sprays and a handheld shower. It'll be a Delta system so no more than two of the components can be on at once. My question is:
Do I really need two 2" or one 3" drains to cover this?
If so, which is best?
If the two 2" then do I just plumb them in in series or do they have to have separate drains?
If the one 3" will I have to run a full 3" drain line all the way to the main drain line in the house?
If two 2" how do I build a proper pan to slope it correctly?
Many thanks for the help.
Directly to trap or a couple of 90s first.
Question for the group. I have the 3" waste line run, but now I need to plumb the shower drain. I'll be using a 3" Kerdi Drain. My problem is two fold. There is a floor joist in the center of where the drain should go, so I assume I can just shift it to the left or right to go around the joist. Is that right?
Also, there isn't enough room under the exit to run the drain directly into a trap. Is it OK to go drain, 90, short pipe (like 16"), 90 into the trap, then slope to the drain? The "old" shower I'm replacing had 4 90's before the trap. This would only be 2! :)
Thanks for the help.
