240+ US utility districts run active rebate programs for WaterSense-certified toilets — typically $25–$200 per fixture. In drought-zone states (CA, TX, AZ, NV, parts of FL), the rebate can pay for the toilet itself. Here's how to identify rebate-eligible models and how to find your local program.
What "rebate-eligible" actually means
To qualify for most US utility rebate programs, a toilet needs:
- EPA WaterSense certification (1.28 GPF or lower)
- MaP score of 350g or higher (most modern WaterSense toilets meet this easily)
- Replacement of an older toilet (pre-1992, 3.5+ GPF) — many programs require photo evidence of the old toilet being removed
- Installation by a licensed plumber in some commercial programs
- Receipt and serial number documentation submitted within 60–90 days
The volume rebate-eligible models
