Step 9: B) Pedal Control: Introduction
My solution is a pedal controlled valve. To push myself on the motivation factor a little further, it's a momentary valve--the water only turns on while I'm pushing the pedal. That might seem to make it hard to turn around and such. Turning around does require turning off the water momentarily, but operating the pedal from different angles is no problem, and it quickly became second nature, even before my morning coffee. The pedal makes it very easy to turn the flow on and off as needed.
Falls in showers are a common cause of injuries, so if you or some of the people using the shower are at risk for falls, consider whether you want to include this feature. If it makes sense for some users and not for others, the pedal can easily be hung out of the way for people who don't use it. Installing a non-slip mat or grip tape on the floor and grip handles on the wall are good ideas in any case.
