Just wondering if kosher to use a Fernco donut fitting inside a schluter (2in PVC) drain? I assume they make one that would seal up inside there as if it were 2in PVC, then connect to an old 1 1/2in iron pipe that heads into the trap below. The issue is the old iron pipe is circa 1938 and comes up out of the concrete basement floor. I want to raise the subfloor as little as possible, and minimize risky contact with that old pipe.
For background, we've removed an old tub from this basement bath and have a stub of 1 1/2 in pipe (good threads, at least) coming out of the concrete floor. My wife wants a steam shower and has chosen an EPS shower pan (custom) from a company that designs them to work with Schluter drains. I assume using a different brand of drain with a shorter profile is a no-no given the bonding requirements for the Schluter membrane? Building up the subfloor to accommodate the Schluter drain body makes the shower too short, and cutting out concrete around the old pipe is dodgy given the age. I've looked through a couple threads on this issue and wonder if there are any shortcuts available.
Here's a pic of my pipe, with a 2in PVC spigot adapter end showing. Using a 2 by 1 1/2 iron bushing would get me into the Schluter drain w/ 2in threads, but still requires raising the subfloor up a ton. Basement bath, of course underneath radiator pipes, so the finished height is the problem. Any ideas?
