Back to Wall and Floor-Mounted Toilets.
Back-to-wall toilets (also known as floor-mounted toilets) are one of the most common toilet types. Back-to-wall toilets are very affordable, easy to install, and stand the test of time.
These toilets attach to the wall, meaning that pipes and wastes can remain hidden from sight. Some back-to-wall toilets even have cisterns that sit within the wall, saving even more space in your bathroom.
