What are the steps involved in planning your project?

Before you begin installing your wall-mounted toilet, you need to plan out the project. This will help you avoid any problems down the road.

Here are the steps involved in planning your project:

1. Measure the space where you will be installing the toilet. Make sure that the toilet will fit in the space and that there is enough clearance for the door to open.
2. Decide where you will place the toilet flange. The toilet flange should be installed at least 12 inches from the wall and 18 inches from the center of the toilet bowl.
