My husband (5'10") has two compression fractures of his mid back, the last one about 4 months ago. His DR & PT suggested we get a hot tub to help with his recovery, especially the severe muscle spasms. We only want a small 2-3 person spa because of a room issue. I've looked at the Clearwater Signature XS76R, Jacuzzi J-315, Allure III A5932-1 and the Marquis Spirit. All are in the same price range within $900 of eachother. Does anybody have recommendations on which tub to go with? Thanks for he help.
