I wanted a higher shower head, I am tall.
Wife has the same water addiction as stated, needed an easier leg method(we get the AARP Mail),and wanted an easier tub cleaning, and washing her wiener(dog) Ms MaggyMay.
Waterpik Medallion 5-Spray Hand Showerhead in Brushed Nickel-LAT-569 - The Home Depot
We have the crappy 1 handle, fullflow to get hot flow type faucet, too much trouble to swap. The only way is to restrict flow.
It is not the same exact brand shown, but it does:
Restrict/adjust flow at any temp.
Shut completely off.
Adjust pattern x5
Has worked well for 5 years
It was not a cheap unit, 125or150 IIRC. I think the dog likes it most, you touch that handle, she jumps in the tub.
Good Luck
