My daughter has just got rid of her Laz-e-spa hot tub that she originally bought to treat a sports injury prior to finally having major hip surgery. They are quite expensive to run, thecost of the special Water treatment chemicals, test Kit supplies, electricity to heat the water and the filter system, plus the cost of the large volume of water itself via her Watermeter, made it more expensive than a good quality gym membership with a wider choice of treatments available.
The home tubs have to either be housed undercover indoors, or restricted to summer only use as they are prone to freezing over winter. They also take quite a lot of time and effort to keep clean and maintain, just like a swimming pool does. The Hot Tubs that are often installed at larger leisure centres also have built.in Disabled Access, either by shallow steps, a gentil slope, or even a hoist in some places, allwith very good grab handles and rails fitted, somethingthat the home tubs are mostly sadly lacking in.
