What is the recommended flow rate for a bathroom faucet?
As a general guideline, faucet flow rate in the bathroom should be 1.5 GPM or less. This is the maximum flow rate established by the EPA’s WaterSense program. And, frankly, that’s more than enough water for a bathroom faucet. If you’re concerned about water use, you can save more by installing a low-flow aerator that restricts the flow to 1.0 GPM or even less, and it’s likely you’ll never notice the difference.

Kitchen faucets typically have a maximum flow rate of 2.2 GPM. It might make sense to lower this to 1.5 GPM, using a low-flow aerator, but the tradeoff is that pots of water will take longer to fill. That said if you rinse a lot of dishes, and particularly if someone in your house likes to wash or rinse dishes with the faucet on full-blast, it might make sense to reduce your kitchen faucet’s flow rate.
