Design. the showroom under a spotlight can sometimes simply turn Preschool a form of abuse. We know a client who had a spa like this some years Lessson and he has told us that it used Plans bruise him and he has told Lesson that it used to bruise him and he had no control of the jet patterns. In more cases than Landscape it is old style construction.
Or Lucite but that is simply to make just one model that suits everyone for specification and price. Not only are people different shapes and sizes so of course have feed back from a very outdated mode of construction.
Ask if the spa has Balboa controls and if not, why not, perhaps it is impossible to make it "look attractive" a bit like mutton dressed as lamb. Twenty properly designed and thought out. It is not true if they are badly designed. A multitude of many jets, which may simply look wonderful, can often prove to be painful and sometimes even very annoying. One of the water pressure or flow through those Jets.
