BTW, How tall to the floor?
its 6' 4" tall at the front so I could stand and stretch. It slopes to 6 foot at the back for runoff.
the bottom window sill height is set for a specific chair height, so a good gun rest can be utilized.
if done again, my windows would not be that high. Lets in too much light and the deer have looked up there and spotted movement.
The top half of the windows are now spray painted flat black. Much better.
As far as a urinal, no problem. Some of the hunting catalogs have a device that screws onto a 2 liter bottle. It has a small fresh water reservoir above the opening. One does their business in the opening, open the valve for a small flush, and put the stopper in it to keep any odors in the bottle.
I'm thinking a guy could run a hose to the ground, dig a hole, fill it with gravel, put the hose in there, and cover back up with dirt. Kind of a redneck septic tank.
