Combining my experience of not taking too hot and too long of a shower less I sweat the bag off I gave it a shot.
Took the belt off and stepped backwards into the shower so the water was running off my back.
Washed everything except my ostomy area and saved that area for a wash cloth area cleaning and wiping.
Turned off shower and towelled dried, put the belt back on and I was back in business.
WHY DOESN'T ANYONE TELL NEWBIES THIS NEAT TRICK?
Now I can go back to showering daily. Hurray!
