Because I just have to do things oddly...

[Layla-Gail O'Brien]

*Storytime*
For my family; I manage a 38-acre, private, saltwater lake property on the Intercoast of Texas with fishing & camping for a membership fee. Except, people don't want to come camping because we don't have a proper 'Bath House' just an accessible 1/2-bath restroom.

I looked into renovating our "clubhouse" thinking; 'Surely we can do a full restroom & include a shower... campers will be so happy! But permitting said I have to raise the building 8-10ft (more than the 5-6ft it is already) & build-out to commercial standards...which is WAY too expensive for us! Apparently, we're at a ground elevation of around 6'AMSL, the base flood elevation here is 20'AMSL, so nothing can be constructed below that point.

Last season, I plumbed-up a couple 'cold-water only' outdoor showers. They're awesome... when it's 5th level of Dante's inferno outside. I can't imagine why nobody WANTS a cold shower, in front of God & everybody, as the ONLY bathing option for a weekend camping trip (sarcasm); but they certainly don't when it's 45 degrees, gusty winds & a water temperature 0f +/-50 degrees...or when it raining, or once mosquito season is underway.

So, thinking outside the box, I'm trying to build a portable restroom/shower house on an RV trailer frame to 'work around' the elevation & commercial requirements. My design has three full baths with showers, one being accessible, & two 1/2-baths on a 10'x22' trailer platform with Two tankless propane water heaters for the shower stalls. Because it's on a trailer & can be moved, it doesn't have to meet elevation requirements. My problem is, I only have about 24" of ground clearance to work with for my DWV systems & part of that is obstructed by the trailer frame...oh, and I'm doing a greywater system for the shower & lavatory sink to minimize the water that goes into the portable blackwater tank for storage & dumping...& I'm limited to 14' by in height restrictions to remain legally portable (I already have "wide-load" permitting covered).

My question is: Where can I find the actual measurements of plumbing fittings in order to calculate accurate space requirements? Can I use fittings that may not (actually) pass muster, code-wise, but will still FUNCTION as far as the systems are concerned? And; what's the MINIMUM height that vents need above a roofline?

Long story; short questions...LOL Thanks in advance!

I suspect you mean fixtures. The minimum for a house is that the toilet needs at least 15 inches of free space to the left and right of the mid-line. That is not affected by the actual toilet size. Most extended toilets extend about 29 or 30 inches from the wall.



An alternative may be a shower room that will float in the event of a flood. https://www.greenmatters.com/home/2018/01/04/ML8rn/engineers-have-developed-a-system-to-make-houses-float-during-flooding

Your trailer idea is probably a lot easier. Try this in a search engine search: shower trailer

I actually looked at shower trailers for my inspiration...do you know those things cost about $60K? I also thought about the floating idea, but I'd still have to pump holding tanks, water sourcing would be a problem & a leak could devastate our estuary lake!
As far as sizes, I actually want the sizes for fittings (e.g. a long sweep, cross-Tee)...if a 3" Long sweep is 12" ut a sanitary T is only 10 I gain 2" in drop clearance to work with...
