Back Outlet Toilet Reviews

If you’re preparing to add or replace a bathroom toilet in your home or business restroom, it’s important to know if a back outlet toilet is the best option for you. This type of toilet typically takes up less room and fits into a smaller area, creating a great space saving solution for small bathrooms.

What is a Back Outlet Toilet?

A back outlet toilet, also referred to as a rear outlet toilet or back flush toilet, is different from a standard toilet in that instead of the plumbing going down below the toilet in the way that we are most accustomed to, it goes into the wall behind the toilet.

There are several reasons you may need a rear outlet toilet. Here are just a few:

  • You are remodeling or renovating a bathroom where the existing pipes are already run through the wall behind the toilet
  • Your bathroom sits on a concrete slab or other orientation where it is not feasible to run pipes below the toilet
  • Your bathroom is above another floor where the ceiling below does not provide room for downward piping
  • The clean lines and minimal footprint of a back outlet toilet works best in the tight confines of many smaller bathroom and half-baths

In short, you can install a rear outlet toilet where you never before thought it possible.

Whether you are looking for a floor-mounted or a wall-hung toilet with tank, here are some of the top rated back discharge toilets to consider for your home, garage, office, or other location.
