We are offering here the Wall Hung And Water Closet is a system in which the toilet bowl is mounted directly to the wall, while its tank is installed inside the wall. This allows wall hung toilets to take up less space. It makes it simple to clean beneath the bowl, and its smooth surfaces make it easy to wipe down. The Water closet is just another name for a typical gravity flush toilet. If you want to get detailed, âwater closetâ can also be used to describe a small room that houses a toilet. Wall Hung And Water Closet is very efficient.
