Inflatable shampoo/bathing basin. Suggestions?

I was considering buying one or both of these products (the EZ Shampoo Basin and/or the EZ Bathe Washing Basin) . . .

wondering if anyone had tried these or any other products they would recommend -- my mom is bedbound, but she can get out of bed to use a commode or sometimes walk a few steps.
