A complete shower room is a sanitary unit consisting of a spray device, shower room body, shower screen, top cover, base or bathtub, without a steam generator. The basic structure of the shower room is a base with a railing. Complete bathrooms originated in Japan. In order to ensure high quality and rapid completion of a large number of athletes' apartments for the 1964 Tokyo Olympics, the Japanese invented complete bathrooms that can be assembled on-site. As of 2014, 95% of bathrooms in Japan are complete bathrooms.
The advantages include the ability to divide into independent bathing spaces, saving space, preventing water splashing, providing heat preservation in winter, and having a beautiful shape that can be used as a decoration [13]. Complete shower rooms are fully enclosed, have good heat preservation performance, and have independent drainage pipes, so there is no need to wet the bathroom floor. The main material is non-absorbent, non-moisture-absorbing, and odorless. Complete bathrooms are constructed using dry methods and are quick to install.
