You may be right but it's very very seldom that anyone other than us uses our facility. I guess most folks feel as if they're imposing? For me, that half bath would be turned into a desk/office area. The upstairs bath has plenty of room with two vanities and it appears to be a larger, maybe 48" shower? I'm also curious about the number of black tanks. One or both of the stool drains would have to be plumbed a long distance if there was a single black tank. I think that might cause the need for more water per flush and more frequent tank dumping. All that said, I like the layout.I don't think I'd like the trip thru the bedroom to the bath if you ever have any company.
No tellin' what might be going on in there.
The plant has ben tweaking the design on this one. I don't believe a production unit will be ready in time for Tampa.
Delete one of the rear sinks and put in a full size shower. That would make sense to me.
