Taking a bath is a huge problem. Any advice?

Why not just switch to no rinse shampoos and soap instead of insisting on a full bath? Hospitals use this; it avoids the trauma of removing clothing, shivering in a bath or shower, the danger of falling, none of which should be factors in staying clean.

I didn't see any information on your profile. Who is the she you are referring to and what is her condition? Is she ill, disabled, etc.? How are you related to her? Do you care for her in your home or is she in a long term care facility. A few more details might help so others can respond.
