A portable spa/hydrotherapy bath (Whitehawk BN2)

I am URGENTLY looking for a portable bath with a spa/hydrotherapy set-up in/on it, to massively help with my permanent health conditions that include fmg/fibromyalgia/hyperkeratosis, unfortunately to get a spa/ hydrotherapy system let alone a portable bath is seriously NOT possible, because its very expensive, I have a disabled shower but is seriously dangerous for me to use a shower due to health problems inc my balance & weak legs etc. Plus will help to keep me cool during the summer & the rest of the year as well as to give me a safe way of being able to wash & bathe myself etc, Please note that it would have to be delivered to me as I am disabled and housebound.
