The idea is to mantain the comfort of both, shower and bath tub for minimalist design.
Also the shelf area is obtained in the unutilized volume of the bath tub. The original light Hub moved inside the ceiling, used to cover the forced air fan also.
I chose a wall washer light to gain a massive lighting body, hidden spotlight (as not to be dazzled), exploiting diffuse illumination.
I particulary love this color and material scheme, the contrast between warm desaturated colors and the strength of stone. Classic, but different.
