Speedball, you think this toilet group is acceptable? (Those doors have since been blocked in). The left 2" pipe will elbow over to the left to catch the faucet, and then shoot up as a vent stack from the faucet, the right 2" pipe will tie into the vent stack somewhere above the faucet. Thanks.

This will work. However, instead of elbowing over from the left pipe to pick up the lavatory I would install a 2 X 2 X 1 1/2" sanitary tee and arm over to the lav and take the vent off the top of the tee. While taking the right hand pipe off a rolled up wye is the correct way to vent the tub/shower it's really unnecessary since the shower's already wet vented by the lavatory vent. But overall it's a good bathroom group rough in. Good job! Tom

Yes I agree that it would be easier to just install the tee, but there will be a window right above the toilet, so I have route the vent around the window. Thanks for all your help on this project.

Ok first mistake of the project, my tub drain rough is off... I mis-read the rough in dimensions on the whirlpool tub... I set the drain in line with the actual drain on the tub, not the tailpipe :mad: :mad: :mad: So, I'm going to dig up some of the dirt and 45 and 45 up to where it needs to be... will this be OK?

Also, my stub out is 2"... my tub tail piece is 1 1/4? Brass. How do I connect these two? Thanks!

You'll use a 2" compression fitting,(see image) with a 2 X 1 1/4" Nylon gasket to connect the trap raiser to the tailpiece. Tom
