Hi; I have a joist right under where the drain drops from the tub, joists go across the short dimension at 6.5" to 8.25" from studs. I have engineered wood trusses, (new construction) and am told I can't mess with the top or bottom section of the truss. The RO is tight, can't move the tub, and can't switch the hand of the tub, because the same situation is on the other end. Any suggestions?

Can you post a photo ?

Haven't cut the hole yet, so not much to see (new construction), but if you're sitting in the tub, the joist runs left to right, right under the RO dimension for the drain (center at 7.5" from the faucet wall studs). I've looked online at a couple manufacturers, and an 8.5 center is common..

How much room do you have between the bottom of the tub waste and the top of the joist? Have you enough room to build a "dogleg" out of 45's and connect that way? Regards, Tom

Pretty tight; don't actually have the tub on site yet. Is it legal to run a street ell directly out of the tailpipe?

Do you have a choice? While I much prefer 45's over 90's if that's the only way you're going to drain the tub then it's a no brainier. But I would surely have me a access panel behind the tub drain in case I needed tro service it. Good luck, Tom

Hi all:

Here is a couple pictures of tub drain assemblies that may help you in this situation...

They are above the floor rough in tub waste and overflow assemblies...

You should be able to attach onto these in a few different ways that are legal.

Let me know if you need more information on these...

My bad! I should have remembered those offset tub wastes. Nice to know that when my brain ocks up that there are knowledgeable people around like you to save my a$$. Thanks Mark! Tom
