Foldable adult bath (Cottingham HU16)

Hi i was wondering if anyone had a portable/foldable adult bath they wanted rid of? My husband is newly diagnosed with epilepsy and we have figured this is the safest way for him to still be able to soak his muscles after he has seizures but I would be able to tip it if he had one in the water where as I couldn't get him out of a fixed unit :) unfortunately our budget doesn't allow to buy a brand new one so I thought I might try my luck on here!
