We recently installed a skirted whirlpool bath that we also use for showering. The alcove is bigger than the tub, so the unit sits flush against the left wall for proximity to controls/faucet/showerhead. Along the back and right walls, our contractor built a marble tile ledge, ostensibly for aesthetic purposes and to fill in the extra space. It looks fabulous, but when the shower is running, water puddles along the ledge, and drains down the front right side of the alcove on to the floor. I’ve see the plastic wedges that can be glued to the corner to alleviate this, but really do not want to spoil the look of my new bathroom with a cheap piece of plastic (even if it’s effective!). Short of getting mad at my contractor for a poor design, do I have any other options to divert the water back into the tub? Can something be built with tile to achieve the same result? Help!
