The shower head has always done a good job of rinsing my chest, my head not so much.
My DIY fix was to add a bracket to hold the head up in the sky light so it wets my head.
Easy to do just bend a piece of aluminum, drill 3 holes bolt it together.
I got the Oxogenics shower head and held on to the old bracket.
If you're over 5'5" this makes showering easy.
