I am in the middle of a master bathroom remodel and am installing a free standing fiberglass bathtub with supply lines and drain going into the wooden subfloor.
The bathtub is hollow in that it is designed to "drop" over the supply/drains which are hidden under the tub. The faucets are mounted onto the tub with the flexible lines running from the faucets to the copper supply lines. Here is an image showing hot/cold supplies coming up through the floor:
I have pulled a plumbing permit from the city and want to ensure that this complies with plumbing building code.
I am planning on running 1/2" copper under the subfloor and and installing shutoff valves for both hot/cold supply lines above the floor, but under the tub. To install the tub, I will set it 4.5" above its final resting place on 2x4's, get the drain and supply lines connected (there is a special "drop in" drain fixture for this purpose), open the shutoff valves and lower the tub by removing the 2x4's. Then after leveling it, checking for water leaks, etc. it will have a bead of silicone run around the skirt to keep it from sliding around.
Anybody see any code violations? I had one plumber tell me I needed "accessible" shutoffs for the bathtub per code, but after perusing the national plumbing code and Florida Building Code section 606, I can't see any requirement for shutoffs to bathtubs or showers.
I will probably go over to the building department as well, but figured I would ask here. Thanks!
