City Thais use this "bidet".  I thought it was ingeniously simple.  Don't know if it's used elsewhere.  It works!  But the water does splash a little.

There is an 8' high wood closet to the right of the sink. To save space, it was built out of 3/4" birch plywood and finished in eurathane.

The first floor is the concrete slab polished & sealed.  The bathroom floor slopes toward the recessed shower pan.  All  water flows toward the shower.  I enjoy this shower and find the American tub shower upstairs cramped.  This bathroom seems restful, simple on the eye, simple to use & to clean. My sister finds it too rustic.  But I always liked the American barn.

This bath offered unexpected uses.  Visiting little boys vied for the opportunity to go potty in the showerpan, then spray it down with the bidet sprayer!  Potty training made easy!  Also I perfer to use this bath to the Western one upstairs where water can't stand on the floor, because cleaning this waterroom bath is so easy. I scrub then hose it ALL down.   Wished I'd made the bidet sprayer a foot longer and put the linen cabinent higher back or even outside the room.
