A customer of mine purchased a 42"x42" cast iron, free standing, claw foot shower base and I'm having a bit of trouble finding a drain that will work with it. Apparently, this base is made with either a 3 1/2" drain hole or a 2" drain hole. I don't think she realized there was a reason to choose one over the other and she bought the one with the 2" opening. What would you use for a drain for this?
A tub drain will work but because they only have one base that they drill for 2 different drain openings, the sunken area is made for a full sized shower drain. If I install a tub drain, there will be an area around the basket that will hold water and probably discolor. Also, I'm unsure of what would be the best way to secure it from below. A tub shoe isn't the greatest idea because I'd then need to turn another 90 to go through the floor. I'd like to drop straight down into a trap, of course.
Any ideas on a drain that would have a 4" wide cover plate or trim, yet fit through a 2" opening?
