Inflatable bathtubs are generally considered safe for adults. However, this may not be exactly the case if the ones using it are children, seniors, or disabled individuals due to the lack of safety features. For example, the bath rings and bath seats of the tub could easily tip over if you’re not careful enough upon soaking in or getting out of the tub. Also, most of the generic brands of portable tubs lack an anti-slip capability which makes it risky for people with physical limitations.
