Replacing a toilet in Seattle: rebates and free toilets
Updated · Editorial team; not yet technically reviewed
Short answer
The Saving Water Partnership, which includes Seattle Public Utilities, offers a $100 rebate when you replace a toilet older than 2004 with an eligible efficient model. Income-qualified Seattle homeowners can get water-saving toilets for free through SPU.
What's different in Seattle
Is your toilet older than 2004?
- Look for a date stamp inside the tank, often on the underside of the lid or the tank wall.
- Toilets marked 3.5 gallons per flush or more are well past the cutoff.
- No stamp and a large tank usually means an older toilet.
Choosing the new toilet
| Feature | Why it matters |
|---|---|
| Flush volume (1.28 gpf or less) | Water savings and rebate eligibility |
| Rough-in (usually 12 in.) | Must match the drain location |
| Bowl shape and height | Comfort and space |
| Flush performance rating | Fewer clogs |
Installation
Older Seattle homes may have a corroded closet flange or a cast iron drain that needs attention when the toilet comes up. See toilet installation and the toilet rebates guide.
