[VAC] Re: Shower traps

[RJ.Dial@xxxxxxx]

What you describe is one of two layouts for the Airstream "all in one 
shower/toilet bathrooms".  The toilet sits on the shower pan which sits 
on the black water tank, and the bathroom walls are the shower stall 
walls and the bathroom walls at the same time - and the bathroom shape 
is usually square.  This is the rarer of the two, and the shower drain 
usually goes down to a trap via a U shaped cutout in the specially made 
tank.  

The more common layout has the floor two-tiered, with the drain on the 
lower level and the toilet perched up over the tank. These bathroom are 
usually rectangular.

Since the shower never goes to the black water tank, and the tank sits 
up on top of the flooring, conventional traps work fine.

Now, if you are developing a new installation, that's another story....
