We have an old Corner Air Bath will take two people, we both love it !
I think the company went bust. Must be about 20 years old with 240 very small air jets in the bottom of the bath. I like using it to relax in after working hard. The air is heated, The program goes on for 30mins, waits several minutes for the water to drain away and then air pump goes on to blow the water out of the pipes. Only cleaned the air holes about once a year
