Mine is located 11'6" from the entrance of the bay to the edge of the paystation. Height all depends on what type of paystation. Mine is a Standard XP Paystation, and I like mine alittle bit taller so taller truck can use it also. It is 32" to the bottom of the paystation. It all depends on your type of paystation because where you put the money in, put credit card in, get change back, and screen read out need to be easy access. When I did this I got the lowest car I could think of and set my paystation on blocks then the tallest truck that could fit in my wash and set it on blocks to see what height was best.
