pls give me the list of different types of spa and which is the best type of massage...
if you have a pool built with a gunite spa attached, it won't be as great for a massage as some of the free standing spas. Check out pdc spas or artic. they are 2 of the best. there are some pictures of gunite spas on my page listed below to give you an idea.
