I wish. You have the cold and hot water lines and a pump to deal with. I winterize without antifreeze so I run 40-50 psi air through each of the lines with the pump running, the spray hose connected and the spray head turned on. Without the pump running it makes a great closed valve. With antifreeze, you just pump it through each line like winterizing a camper. I never use my shower so it is a PITA in my opinion.
