So, one, did you remove the flow restrictor? If you're into that sort of thing. I don't begrudge anyone not removing them, I'm fortunate to live somewhere pretty wet. But I also can't stand going to stay somewhere, hotel or whatever, and the water pressure is low. I feel like I can't rinse off properly without a good blast.
And so plumbing is fun because you can add stuff too. If you're into it, you can get a valve and wand attachment and make your own custom setup.
Another idea I've toyed with is basically an on/off valve to preserve water while you're soaking up. Can't go turning off the shower because it'll mess with your perfectly set temperature, but if you have a separate valve for turning the water off at the showerhead you can maintain that temp.
Great work OP. I'll think about you the next time I shower.
