Used Pistons to make a 4X4 Shower and bath. Two switches, one for the Shower, one for the Bath. There was supposed to be a sliding Glass door implemented in this version, but the Pistons staying powered glitch ruined that, so, for now this is what you get. Later on I plan on making a taller one, perhaps with only a 1X1 shower head in a 4X4 bath, or even several 1X1 heads in an 8X8, but, lets not get ahead of ourselves.

*Edit*
My Bath House is actually V.2 of this.
