When I looked at the project, I actually thought that the design could become more impressive with a few minimal changes. The tub next to the shower will rise because it is dysfunctional. The vacant space will become more useful with the seating unit and will be separated from the rest of the bathroom with glass panels. This use can be transformed into a sauna-hammam in the future. The washbasins can be redesigned to be side by side against the opposite wall of the entrance. To achieve a modern and spacious look, all cabinets will be redesigned with a cost-effective material that will give the appearance of clean concrete (I thought of this material as autoclaved aerated concrete (aac)).
the shower retains its current position. A 15 cm niche can serve as necessary storage for the shower. The choice of 2 different ceramics will bring the shower to the forefront, and at the same time will not spoil the modern and simple look.
