Check out this Flow bathroom concept from Art-Tic Design Studio. It is based on the point that all elements such as a sink or a bathtub are fused with the surrounding floor and walls. The concept is so calming and relaxing! The floor and walls are made of concrete, as are the elements. The concrete doesn’t seem to end at all. The bathroom looks so fen shui and stylish and eco-friendly, of course, as there are some green plants growing here. Calm green and gray colors ensure relaxation and the tub with a concrete bookcase invites you to lie in the foam for some time.
