Damn they have a $150k minimum on their website they say

Wow, thank you. I just watched some videos on the Schluter website and that’s incredible.

When you say “architectural drain”, do you mean like those linear shower drains?

You sound like you know what you’re talking about. Sure you don’t know anyone who wants the job?

From what I’m understanding “redoing” a bathroom with existing electric, waste, supply, and vent lines is a heckuva lot easier for small folks than “creating” from empty space like we’re talking about

We do have an existing window in the space. The vent stack is right on the other side of the same exterior wall

Thank you. Indeed I have been educated as I understand the scope and magnitude of what we want to do! Part of why I’m looking for a one stop shop.

I also need a good roofer (this dumb house) but that’s unrelated. I saw some recommendations for the Roof Doctor on this Reddit and they are looking nice

I only know enough plumbing terminology to sound like I know what I’m talking about. The cast iron vent comes up out the roof and right on the other side of the “new bathroom’s” only exterior wall, which I think is what you’re asking about. However when I said “stack” I also meant bringing up water supply lines - there is no plumbing (waste or supply) on the 3rd floor at all currently
