Toilets come in an array of styles and shapes; a back-to-wall toilet is a wall-mounted variety not used frequently in residential bathrooms. Since this type of toilet doesn't rest on the ground, you can clean under it easily. However, the weight of the toilet and the person using it can be substantial, so wall-mounted toilets are most common in commercial buildings. Finding one in your home might be intimidating, especially if you want to replace the unit with a new model, but installation is similar to that of a freestanding toilet.
Turn off the water supply at the shutoff valve.
Screw the mounting hardware into the wall around the flange. Measure the distance between the drain opening and the mounting brackets on the back of the toilet if the unit didn't come with a mounting template. Mark the wall around the flange before mounting.
Press the wax seal into place carefully over the flange in the wall.
Enlist a helper and lift the toilet up to the mounting brackets. Press the unit into the wax seal carefully; if the wax seal becomes damaged during installation, the toilet may leak.
Place washers and nuts over each of the mounting bolts and tighten them with an adjustable wrench.
Run the water supply line from the bottom of the toilet tank to the supply inlet poking out of the wall. Secure the bolts with an adjustable wrench.
Place the tank lid on the top of the tank, then install the toilet seat and turn on the water supply.
