I am installing a new tub and wall unit and the new tubs drain lines up right over a floor joist. The old tub drain fit right down the side of the joist. There is about a 1.5" difference between the two tub drains. Any way to get around this without moving a floor joist?

If you can't move the tub from one side or the other then sister in two new joists, one on each dide of the old joist that you need to cut away. If this does not line up then sandwich the two joists together and put on one side, glue and screw them to the old joist.

you can also put two cross braces on either side of the drain and cut a 2" hole just above centre of the joist if you have 2x8 for joists.

Hi Crobin... Just wanted you to know that they make an above the floor rough in TUB waste and overflow... Some sold in brass, some in plastic.. SEE PIC. #1

They also make a side outlet tub waste and overflow assembly... for just your situation... SEE PIC.#2 Should prevent you from cutting any joists.

Try Dearborn Brass for more information on the side outlet drain (just click on bath drains at the site).

Any questions just let us know... Hope it helped... Mark

Hello,

I have this same problem, and I was wondering if the side outlet waste overflow must be in brass, or if a plastic assembly is acceptable in this type of application as well?

Thanks,

logicz...

If you can find one made in plastic...it should be fine! I think dearborn and gerber make these... check with a local PLUMBING SUPPLY STORE.

Good lcuk!

Thanks Mark!

You can actually notch the joist a bit. Do not chop it up too much - just what you need. Yes, you can use plastic drain (ABS or PVC ). If on the second floor - then glue all joints together.

Milo...

Have you seen a side or rear-outlet tub waste and overflow assembly in plastic? Let me know.

Thanks...

I was thinking of PVC (about halfway down is a 1½" 3-way that's NSF rated):
Product Listing PVC-3-ways-side-outlet-90

And pairing it with something like this:
KOHLER: K-7214: Clearflo cable bath drain, less PVC tubing: Accessories: Bathroom

Looks like that would work just fine here Enzeder... :)

Thanks for posting it all...
