: : Only a toilet has its own built-in trap. All other drains musts have a P-trap added.
: Every installation of a tub that I've seen has the p-trap below the subfloor. Are you saying that putting a tub on a concrete floor is different?
The tub P-trap is below the slab. You have to leave a tub box in the concrete.LonnythePlumber.
