What is the typical fixture unit range for a shower?

Explanation:
Fixture units estimate the water demand a fixture will place on the supply, which helps size the piping. For a shower, the design demand is typically about 2 fixture units, and it can rise toward 4 if there are features like multiple heads or higher flow. So the common range is 2–4 fixture units. Values as low as 0.5–1 FU underestimate a standard shower, while 4–6 FU is usually reserved for much larger or commercial setups.
