Don't have a shower, we have a 7 ft long, 60 gallon tub from the early 20's. I soak in it every morning, but it's more for the muscles in my back, shoulders and neck than anything else (an old bicycle wreck left my back a mess). It lets me move freely the rest of the day.
But I've got a pretty "oily complexion" (and hair), so I wash when I'm in there anyway.
A side note on the bike wreck; when you're in a line of traffic stopped at a light or a stop sign, and the passenger says "I'll just get out here and walk", make sure they look before they open the door... it was 5 weeks before I could sit up straight again! The bike never recovered.
