I meant replacing a regular bathtub with a jet tub, not buying an outdoor hot tub--which, delightful as they are, cost $$$ to buy, refill, heat, and maintain. Mom has arthritis and takes a bath in her jet tub every evening before bed--she says it helps the arthritis plus relaxes her for sleep. When Daddy was alive, it was their comforting evening ritual for him to fix them tea, and a little while later for him to draw her bath. She felt loved, and he felt needed and appreciated. I bet that was as good for their health as actually taking the bath!
