In recent years, the overall bathroom made of plastic has been popular in foreign countries. The parts of the bathroom are molded from unsaturated polyester fiberglass. The tub, washbasin, commode and floor, even the wall about 1m high are integrally formed at one time, and then the roof and upper part are integrally formed. The walls are assembled into a unit bathroom. The finished product is reserved with a reserved hole such as a lamp hole, an exhaust fan hole, and a floor drain hole, and no further processing is required.
The plastic whole bathroom is clean, beautiful, water resistant, easy to clean, convenient on-site installation, saving labor and time, and is a major reform of the bathroom construction. Most of these plastic toilets are milky white and milky yellow. They can also be made into various patterns and even inlaid with magnetic plates and other decorations to make a luxurious bathroom.
