Why do you recommend a 4 to 6 inch space between walls and the edge of the SunTouch mat?
This space next to walls reduces the chance of damage to the mat by in new construction or future remodeling. If these issues are not relevant in your case, it is OK to put mats within 3 inches of the wall. Definitely stay at least 4″ from the toilet ring. Another good reason for the gap is to save you money. In most cases, you do not stand closer than 6″ to a wall so you can use less mat by leaving a space.
