I will be installing a shiower that is over a closed in area of the basement. Used to be a porch. How do I install a trap that would be accessable from the the room where the shower will be located. The shower will be all ceramic tile with a built in drain.
Would a drum trap work? Are they legal?
Is there a shower drain that can act as a trap as well?
There should be no need to acces a modern 2 inch p trap from anywhere but through the drain itself, in the unlikely event of a clog. Absolutely do not install a drun trap, unless you like having trouble down the road. Besides, how would you acces the drum to open it up, if it is in a closed space below.
