What is a rear flush toilet?

A rear flush toilet is a model that ejects its waste material towards the back of the toilet fixture. Rear flush models often sit closer to the wall, and provide more water pressure per flush.

Rear flush toilets are able to be secured directly to the wall, taking up less floor space than other toilet types, though they also come with their own downsides. Most contain water pressure devices to aid in the disposal of waste, due to their rear-facing output pipes. Rear flush models are generally more compact, providing a better fit in smaller bathrooms and more flexibility with bathroom design.
