See Sketchup drawings inline below.
Master bath, new location for toilet, shower, and tub (although along wet wall). Double pedestal lavs using old bath drain and vent.
Existing 3" stack, finished space below that we'd rather not blow up. Adhered to 1/4 slope before vents and 2" clearance from joist edges for drilling.
Some notes left to right on the underneath view:
Tub vents after the turn then does a little S jog to match level of the lav line (the one going through all the studs) then joins the stack.
Lav line is pre-existing and uses every bit of joist hole/notch code to slope (2" down at the far end, 2" up on the joist at the last hole).
Planing on a Double Combo Tee Wye at the stack. Only had a model for a fixture cross, so ignore that.
Shower drain discussed below.
Toilet vents after the turn (long sweep). Final location TBD with actual stud placement.
Did not show vents tying in, but they will join the stack about 5' above the ground and then through the roof.
Notes on the shower drain drawing:
Route P-trap (hidden by the joist) the away from the stack to give room to work
Turns ara 45 and long sweep 90
Vent pull off is at a 45 degree angle and gets under the wall
Then joins a slightly angled reducing wye and ties into the combo fitting to the stack. Elbow there not shown, but it should be 1/8 or 1/6.
Vent lines will be combo fittings, not sani-tees (all I had was models of sanitees and wyes)
Toilet line is 3", stack is 3", all others including vents are 2"
Gotchas, critiques, or highlighing any potential problems appreciated. Everything I know about DWV I learned here.
Thanks all,
Anthony
