The so-called dry-wet separation means separating the shower space from the makeup and bathroom space, effectively preventing water splashing and keeping the ground dry. The most important thing for dry-wet separation is to use partition. Affected by conditions such as area and structure, the zoning forms can be flexible and diverse. In the case that it is impossible to install a fixed fully enclosed partition, local shading, such as soft curtains and wide drooping shutters, can achieve the same effect without affecting lighting.
