3/4" plywood plus 3/4" foam is bit redundant. Some curbs are made of foam only, and then the foam needs to be thick enough to be structural. But if you have a 3/4" plywood frame for the curb, you could use 1/4" foam tile board. And at the widest part of the wye, you could certainly notch the 3/4" plywood frame, as long as the wye would not interfere with the 1/4" foam. As to the long turn 90, you could use a street connection there, either a street wye or a street long turn 90.

I guess in your situation, I might be inclined to leave the san-tee but turn the cleanout 90 degrees. That would ensure good access if the san-tee ever causes any trouble. Rotating the cleanout is quite a bit less rework than changing the san-tee to a wye.

[If you never have a backup on that shower drain, the san-tee vs wye will never matter. The concern is that you have a backup that includes solids, some of the solids get lifted into the horizontal vent section, and they don't drain out properly when the clog is resolved, due to the lack of the sweep on the san-tee, and they end up blocking the vent. Snaking the horizontal vent would let you clear that.]

Cheers, Wayne

Agreed. I'm only going heavy on the 3/4 ply because the hollow curb option from Wedi is designed to wrap around 3 2x4s. Their full-foam curb is indeed structural, but not the hollow one, so I need to make sure I can support the weight of the glass wall on top. I'm kind of locked into the Wedi system because it's the best way to address my skills gap in the tiling and waterproofing area. (Even Schluter has more variables than I'm looking to take on)

It makes sense though that rotating the cleanout is the best improvement I can make to this situation, so I think it's worth me bumping out the wall a bit inside the closet. I have one of those little borescope cameras so maybe after a few weeks of shower operation I'll run it down in there and see if there's any buildup.

So does Wedi have the equivalent of Kerdiband? If so you could just use 1/4" Wedi sheets (if they exist) and wrap the corners with Wediband. [Moot if you keep the san-tee and what you have will fit in your planned build up, but I'm curious.]

As to the cleanout, it would be normal just to have a hole in the drywall and the hub/plug showing or sticking out. If that's too ugly even for a closet, maybe you could get a non-flush cover, rather than fir out the whole wall. There are also cleanout plugs with a recess instead of a square projection.

Cheers, Wayne

Wedi has their own Wedi band, but I don't think they have 1/4" panels... but - since it's such a small shower I know the inside of the curb will be getting constant water and likely frequent footsteps, so I'm trying to go with something completely seamless. (call me paranoid but I want to keep my waterproofing application skills out of the equation wherever possible)

There's actually a little more room there than I thought, so I probably won't need to fir out the wall. The reason I'm trying to be so neat about it on the other side: It's my daughter's room and still being pretty young, she actually still considers the closet fair game for hide & seek and a bunch of other purposes aside from storage. Happy Thanksgiving! Appreciate all this advice and conversation.

I may have missed a comment but in your photo you show 2 pvc lines joined in the wall your santee needs to be inverted . also how are those lines glued together on such a radical angle ? it appears like the joint must be severely cocked , Could be just an illusion

Hi Jeff, no, you didn't miss anything... just me being an amateur. My logic in setting it that way was to encourage any rain getting into the vent to go straight down instead of taking the turn into that horizontal-ish pipe - maybe that logic was faulty. Since that's just a vent (and above every flood plain in the whole house) I'm hoping that the direction of the santee isn't a huge deal.

As for the cocked joint, if you mean the same one that feeds into the "side entrance" of that same santee, it's a little cocked but mostly illusion. Photographing this inside a tiny bathroom required some interesting angles. I had the pleasure of some heavy rain the night after I installed all this so I'm cautiously optimistic that the joints are good, although these lines generally stay pretty dry year round.

Ok good it looked like it was really tweaked. santee is upside down cant see it a problem but something would usually get a correction notice and a kick in the butt by your superior. Normaly a vent like that can be completly flat I usualy go for around 1/8 per ft to a 1/4 inch sometimes I let it scream with a 1/2 inch perfoot but totaly unessesary and not so neat to look at .

As far as I can tell, it's not a code requirement even though inspectors may be calling it. If you have a code citation that says otherwise, please share.
