Amazon has what is called "Sitz Bath." it is a shallow thin plastic bowl. You fill it halfway with warm/hot water and add a little baking soda or Epsom salt. Lift the lid and rim of the toilet and place the bowl on the porcelain rim. It will fit either round or oval. It is a pleasant way for elderly to clean the worst parts --I don't recommend soap as it can't be rinsed off easily, but I actually like Noxzema on a washcloth. It won't matter if a little is left on the skin. A towel will take it off.
