I have seen many examples where a concrete bathroom look is achieved with concrete floors or a concrete sink to add a touch of the beautiful rough effect in the space. A concrete bathroom floor can be planned from the beginning of the design process, or it’s often used as a treatment on top of tiles that no longer fit the style of the space (a relatively easy and budget-friendly makeover in a way).

The concrete flooring in this bathroom extends out to the walls and even the ceiling for a full concrete bathroom effect where the white sink and toilet really stand out. This colorless look has a very industrial aesthetic, with the smooth surface of the concrete and the shiny porcelain pieces balanced out with a few wood tones in the ladder and the little shower table.
