As I age, I find my legs are not as strong and I am more concerned with having a serious fall especially when showering. I use grab bars in the shower and that helps, but in the last few months I still didn't feel totally safe. I found my showers did not last as long as I would have wanted and I couldn't safely wash my lower legs and feet. Since I am 6'2, I needed something that would be easy for me to sit down on and get up from. I just purchased a shower stool with back and arms. The seat height can range from 17" to 27". I really like it and feel much more comfortable showering. Being able to use both hands without fear of falling has been wonderful. Even, better is not having to rush.

I second that! Please post a URL to the chair - it is very hard to find shower chairs that go that high. The typical height is too short for taller folks.

I recently purchased a transfer bench with a slide/swivel seat. link
I also purchased the optional leg extensions for more height. It can be used with tubs and large showers. Very well made in the USA. (I think it was available via the KDA shopping link to Amazon.com) Problem to overcome is a shower curtain - I just bough a cheap linen liner and cut two splits to fit over the bench - works fine.

Another related purchase I am happy with is a hand held shower by Moen. Nice light weight. long hose. Handle only shuts off to trickle but other wise a very nice product. Got mine at HSN best price and free shipping.

The stool I am using is a Drive Medical Equipment Model # 12455. The link is Drive Stool.
