I have dry tested and wet tested (yes dry tested as suprisingly there are dealers who don't put water in their tubs) models from Hot Springs, Coleman, Vita, Caldera, Jacuzzi, Sundance, Master Spas, Marquis and probably a few I am leaving out.

Only the Marquis comes close to fitting my body. I have a very long torso so the neck jets always hit below my shoulder blades. I could buy an open deep round tub but the jets wouldn't be near my neck. I find hunching down to use the neck jets puts a lot of uncomfortable pressure on my lower back. It seems I live in a world where everything is designed for people 5'10".

Surely someone makes a model of spa to accomodate taller people? I'm by no means a giant. The closest fit is the lounge in the Marquis "Reward".

I'm 6-3 and have an older Sundance Cameo, and it's therapy seat fits me perfectly, with the neck jets hitting just right. I agree finding a tub that fits us "tall people" is difficult, but keep the faith, your tub is out there somewhere! Might not be a bad idea to keep the older spas in mind regarding this. Also, sometimes you can have a custom spa made, in which additional jets are placed higher in the seat (if the design allows).
