Low Shower Clearance in 1690's house

[Quakertown]

View attachment 52527 Hi all. We have a really old house, trying to make more livable so you don't have to go downstairs and to the other side of the house to go to the bathroom in the middle of the night. SO. We have very low clearance on our new upstairs bathroom due to exposed beams in room below(so can't run plumbing in ceiling/floor). Looking for lowest clearance possible as close to code as possible. Have about 6.5" clearance for toilet and shower drain. Wanted to try the shower draud attached. Is it near code? Also same question for toilet. It's hard to make things work perfectly in this old house! I've talked to a number of plumbers - done give me a quote and don't see any issues, a few talk through all the reasons it won't work so wanted to see what you all thought.

Is it near code?

No. The "water seal" AKA "trap seal" is either non-existent or too small. You should have a water seal of 2 to 4 inches.

It is a "legal" drain and has proper trap seal. Its design avoids becoming an "illegal" "S" trap.

Seal seems low... Not sure how you would measure... top red to green I would think.

To be safe, call them to verify what certifications it has. My guess is that it has approvals. It would be nice if they included that on their data sheet. They've been around for 12-years or so, so aren't some fly by night company.

Sorry I cut out part of the spec sheet to keep the file size down- it says it needs to be verified for code locally . I reattached below. That's of course a great call- I'll call the company andawas and thinking even to cAll the inspector but I feel like if I go ahead and install, since most of you think it's viable and more important than if it passes inspection that it will actually do the job- I might go ahead and use it - because there aren't too many solutions for this left and I feel like there is a little leniency when trying to make a 300+ year old house livable. Thanks for all the responses.

Hello again. I called Prier who makes the product and got another spec sheet which also shows the 2" water seal that was mentioned by Reach4 above, so that is useful. I'm now speaking with local distributors to see if they've had any issues locally installed. They did say they don't have any specific certifications which seems strange, might need to try a different rep.

Nice find. Looks like a great product for your shower.
