Thank you for your contest, For this project I left the position of the sink wc and shower the same in order to contain the costs and use the savings towards better materials. Frist I introduced a bidet, which is in my opinion what can change a bath from basic to luxury. I put a large and comfortable shower instead of the bathtub. I used a resin flooring and in the render it is black but can be done in another dark color. I really like the contrast of ceramic that comes out in dark environments. The wall painted with resin for material. You have to keep in mind that resin is a very strong material, cheap and easy to install. It is very fashionable and durable. For more than 10 years I have used resin and no one has ever complained. Under the sink you can install a wardrobe to store all bath related stuff.
