Hey all, I give my mom her shower a couple times a week. She has a walk in shower that has a chair she sits on because of mobility issues. She has a for of Parkinsons. Well long story short. She sits on the shower chair and I don't think her bottom gets cleaned because you can still smell her. Are there any types of inserts that fill with water she can sit on her shower chair to soak her bottom? It is getting unbearable to smell her. Any suggestions appreciated. Thank you everyone...
