Hi
I'm planning on forming and casting a Japanese soaking tub (Ofuro) from concrete. The tub will sit on a sturdily reinforced slab on grade concrete floor. Dimensions will be 42x42 by ~36" high and the walls will be ~4" thick. (The slab has insulation, PEX for radiant heat and vapor barrier under it in case that matters).
When my plumbers did the under slab rough-in, they boxed out an area under where the tub will eventually sit, leaving what amounts to a hole in the slab where the trap and drain will presumably be brought up.
Questions:
#1. Can I have the plumber install the trap and drain at the appropriate location/height and then pour around them, filling the hole and forming the floor of my tub, or is there a reason these can't be embedded in concrete?
#2. I assume a regular tub drain and stopper mechanism won't work in this situation. A floor drain and flat rubber stopper are fine as far as I'm concerned, but will this meet code? Is there a better solution?
#3. What about the overflow? Do I have to have one? If so, how to do in concrete?
#4. I was told that it's a bad idea to put valves and fixtures directly in concrete because it makes repair or replacement difficult to impossible, so I've planned to locate the fixture in a framed wall that backs up to one of the tub walls. Is there any better way?
Thanks in advance for any advice!
