Can you recommend a good low flow showerhead?
The following are two manufacturers that use a maximum of 2.5 gallons per minute (as a comparison, most showerheads before the 1990s used 5-7 gallons a minute) and offer great design at a price:
Hansgrohe (2.5 gallons per minute flow rate)
Kohler (2.5 gallons per minute flow rate)
Alternatively, these two companies offer affordable showerheads with great water efficiency:
Bricor (1 gallon per minute flow rate)
Oxygenics (1.5 gallons per minute flow rate)
Hope this helps!
