Thank you for your inquiry! The Delta Foundations Lavatory B2511LF-SSPPU-ECO faucet is designed with a 1.20 GPM at 60 PSI flow rate aerator. However, there is an aerator with a maximum 1.5 GPM at 60 PSI flow rate made for this unit too. This would be the only way to increase the flow rate of this lavatory unit.
