I am replacing a second floor existing tub/shower and was going top put in a new tub but wanted to look into what it would take to convert to a stand alone shower and after removing the tub surround I realized that I have just a 1 1/2" drain line to work with. It continues as a 1 1/2" line horizontally to the vent connection and beyond horizontally then down so certainly no easy replacement. So I then looked up section 408 in the 2018 WA State Plumbing code and it says this:
So it appears that the exception may allow for this (with AHJ approval) so the code seems to believe this is acceptable with the correct condition of one showerhead with 2.5gpm or less. I was looking at a prefabricated base with a 3.5" curb so there will be some water retention ability, but my ask is this:
Just because I may be able to do it, would it work well? Anyone have experience with using a 1 1/2" shower drain?
