I was at an RV show today and saw this dry bathroom in a class A. It was very compact and looked like a great answer for a B or C. It was in a Thor. I think this was it, but it looks bigger in this floorplan than it was in real life. The shower was very small and had a curtain instead of doors. There was very little wasted floor space. The door opened to close off the hallway to give you plenty of space to change.

Did you get inside the shower and sort of test it for 'feel'?And, sorta off topic, but I've always wondered: Why aren't dimensions included on floor plans???? If the above pic's an "A", it's likely an eight foot plus wide rig. But on a B...25% narrower!

It looks like a four foot space, not too hard to find behind the axle of a C or a short wheelbase small A. In a B there will be a little more to finding a space for waste tanks, depending on chassis and fuel tank and filler location. I see that configuration fairly often in small TT's, only for those it is in a rear corner, and they often put fresh water tank at the other end for balance (which is kind of screwy if you think about weight distribution changing as the water gets used).That would be the Axis 24.1, 25'6" long, 94" wide, on a stretched E-350 bare chassis. Most Cs are somewhat longer, might be 8" wider, and can carry another 2000 pounds than this thing Thor calls a RUV.

Francesca: I didn't get inside the shower. I should have. It's probably a bit too square for a true B. Maybe it would work in a widebody or a small C. If you lost/moved the sink it might work on a standard B. It seemed like a better use of space than the bathroom in a pleasureway pursuit. It would be nice if they had dimensions and things were drawn to scale. Based on the size of the bed it looks like it is about 38" x 48"tatest: Is this bathroom any harder to find tank locations for than other Bs with a bathroom in center?I wondered about the weight distribution thing as fresh drains and black/gray fill. How is that resolved on any RV? I guess it makes less of a difference on a heavy A/B/C than on a small light TT. Do any brand TTs do it better than others?

Seems to me that can make a difference even in some bigger units...

Tank locations for a B depend in the chassis selected. On the Express, the biggest space for a black tank under the toilet is just forward of spring mounts for rear axle, curb side. That's somewhat rear of "mid" and not really enough room to put a 75" bed lengthwise behind it.On extended Econoline, all the big spaces were behind the axle, with another streetside forward of the fuel filler. I know these spaces well, working on my own (unextended) conversion.Sprinter has a lot more flexibility, spaces foward of axle on both sides for 6-10 galllons of tank, a lot more in the rear, which is why you see most "full bath" conversions on the Sprinter located at the rear of the van. More often, with bath forward of axle, toilet will be on one side, kitchen on other, to use the underfloor spaces on both sides of the chassis.There is yet more flexibility building B+/C/small A on cutaway chassis because except for tailpipe and fuel filler pipe, all the space outside the framerails is available, and height of space can be much greater than under the van floor, because RV floor is usually at least 2" higher and is often located another 6-10 inches above the framerails. All this space to be traded utilities vs storage bins gives A/C motorhomes more layout flexibility than in van conversions.You could proably put that bath in a 24-foot Sprinter, foward of that bunkroom configuration, but there may be less room opposite, and you would have a smaller lounge area forward.To put that bath in a LWB Express, you could maybe flip it and move it to curb side, but to put it forward of that kind of bunkroom, you would probably need a long offset drain from the toilet to a tank located further aft. Or you could do a combined tank for toilet and shower, or maybe better, a cassette toilet.I don't know enough about under-floor configuration of Promaster and have not yet seen the U.S. version of the Transit. I've seen enough of the Nissan to know that any sort of bathroom might best be done with a cassette toilet, keeping most of the conversion above floor level.

REALLY small TT's often have the tanks in virtually the same location- fresh above, used below; or side by side.
