    Depends on the state you live in really...

    It may also depend on whether these fixtures are above ground or if the plumbing for these fixtures will be below a slab.

    If the pipes are above ground then all states that I know of will allow two toilets and two sinks on a 3" drain line. If you are below slab, you may need to bump the drain line up to 4"... ;)

    Check with your local plumbing department for best answer.

    Mark is correct. It depends upon your local plumbing code. For instance, in Manatee County you can go 3 inch but in Sarasota County it increases to 4 inch. Check with your local building department. Good luck, Tom
