Bathroom walls

Well, I am standing where the toilet will be.
The bathroom walls will support the bedroom loft platform, which will etxend to about where my blue shoulder is. The walls are 74", and the room is 48" X 75".
TEE HEE!
Straight and true.
bathroom and bedroom coming together
curve and ladder infrastructure. The curve is to make it easier to get into the bedroom, closet area, and to the ladder that will go up into the loft.
the bath tub will fit into the curve.. 30" by 48"
