Toilet Rebate Programs 2026: Find Rebates in Your Area

What Is a Toilet Rebate Program and How Does It Work?

Toilet rebate programs exist because water is a managed, often scarce resource. When a utility can encourage customers to save water at home, it defers the need to build expensive new treatment or supply infrastructure. The math is straightforward: a single household that replaces a 3.5 GPF toilet with a 1.28 GPF model saves roughly 13,000 gallons of water per year. Multiply that across thousands of households and the savings justify the rebate cost many times over.

Programs vary significantly in how they are structured. The most common formats are:

• Mail-in rebate: You buy the toilet, fill out a form, and mail in receipts and sometimes photos. The rebate arrives as a check or prepaid card within 4 to 12 weeks.
• Online rebate portal: Most updated programs use digital submission. You upload a receipt and installation photo through the utility website. Approval typically comes within 2 to 6 weeks.
• Instant in-store rebate: Some utilities partner directly with retailers like Home Depot or Lowe's to discount qualifying toilets at the register. Less common but growing.
• Bill credit: Your water bill is reduced by the rebate amount in the months after verification.
• Free toilet exchange programs: A smaller number of utilities simply give away a WaterSense toilet at no cost, often through a pickup event or delivery program. Common in California, Arizona, and Texas during drought years.

How Much Money Can You Actually Get Back from a Toilet Rebate?

To give you a concrete sense of what is available, here is a representative sample of active or recently active programs across the country. Always verify current amounts directly with the issuing utility, as rebate pools are refilled annually and amounts change.

Note that this table represents a snapshot of programs that have been historically active and should be used as a starting point for your own research. Rebate pools are often limited and close when funds run out. Programs in Florida, Georgia, and the Mid-Atlantic states also exist but tend to be smaller and more localized to specific water management districts.

Which Toilet Models Qualify for Rebates in 2026?

The WaterSense label is the near-universal gateway to rebate eligibility. A toilet earns the label when it uses 1.28 GPF or less AND passes MaP flush testing at a minimum of 350 grams (most WaterSense toilets score 600 to 1,000 grams). This dual standard -- efficiency plus performance -- is what makes WaterSense the benchmark programs trust.

Here is a breakdown of commonly rebate-eligible models by brand:

TOTO

TOTO leads the efficiency segment. The TOTO Drake II (1.28 GPF, two-piece) and TOTO UltraMax II (1.28 GPF, one-piece) are WaterSense certified and score 1,000 grams on MaP testing -- the maximum. The TOTO Aquia IV dual-flush (0.8/1.0 GPF) qualifies for the highest rebate tiers that reward ultra-low-flush designs. TOTO's CeFiONtect glaze also reduces cleaning chemical use, which some programs recognize as an added sustainability benefit. All TOTO WaterSense models are searchable on the EPA database under manufacturer "TOTO USA."

Kohler

The Kohler Cimarron Comfort Height (1.28 GPF) and Kohler Highline (1.28 GPF) are both WaterSense certified and widely stocked at national retailers, which simplifies rebate documentation since receipts are straightforward. The Highline Arc (1.28 GPF) is among the most commonly listed models in utility rebate databases because of its combination of certification and retail availability.

American Standard

The American Standard Champion 4 HET (1.28 GPF) and American Standard Cadet 3 (1.28 GPF) are WaterSense certified. The Champion 4 HET is a redesign of the original Champion 4 specifically aimed at the rebate market -- same 4-inch flush valve design but engineered to hit the 1.28 GPF threshold. MaP scores for the Champion 4 HET reach 1,000 grams. The Cadet 3 scores 800 grams. Both qualify for the majority of utility rebate programs.

Woodbridge

The Woodbridge T-0001 is one of the most popular one-piece toilets in the mid-price segment and carries WaterSense certification at 1.28 GPF. Its skirted trapway design and dual-flush button (0.8/1.6 GPF option on some variants) make it eligible for programs that accept dual-flush models. Confirm the specific model number with the rebate administrator, as Woodbridge offers multiple configurations.

Swiss Madison

Swiss Madison offers several WaterSense-certified models including the Ivy and Ivy Pro (1.28 GPF). These one-piece toilets have gained traction as budget-friendly alternatives that still meet rebate requirements. Check that the specific model number appears in the EPA WaterSense product search before purchasing for rebate purposes.

Gerber

Gerber offers WaterSense certified options including the Gerber Viper and Gerber Maxwell (both 1.28 GPF). Gerber toilets are well-regarded for commercial and multi-family applications and appear in utility databases for both residential and commercial rebate programs. Gerber's ReadyLock installation system is also compatible with plumbing efficiency upgrade programs.

Where Do You Find Toilet Rebate Programs in Your Area?

Here is a step-by-step process for finding every available rebate before you buy:

1. Start with the EPA Rebate Finder. Go to epa.gov/watersense and use the rebate search tool. Enter your zip code to see programs currently listed for your area. Note that listing is voluntary, so not every utility appears here even if they offer a program.
2. Call your water utility. Find the number on your water bill. Ask specifically: "Do you currently have an active toilet rebate or replacement program?" Programs open and close throughout the year. A live call surfaces the most current status.
3. Check your city or county government site. Municipal sustainability offices often run separate programs from the utility. Search "[your city] toilet rebate 2026" and check the official .gov or .org site.
4. Check your state water resources agency. State-level programs are less common but higher-value. California's DWR, Texas TWDB, Colorado Water Conservation Board, and Arizona DWR all have or have recently had statewide efficiency incentive programs.
5. Check the Alliance for Water Efficiency database. The AWE maintains a comprehensive, third-party maintained database of water efficiency incentives at wateruseitwisely.com and alliance4waterefficiency.org.
6. Ask at the retailer. Home Depot and Lowe's sometimes partner with local utilities for instant in-store rebates that do not appear in online databases. The plumbing department staff is usually aware of current partnerships.
7. Check for income-qualified programs. Many utilities run separate, more generous programs for low-income households. LADWP's Water Savings Assistance Program, for example, provides free water-efficient fixtures including toilets to qualifying customers.

What Are the Eligibility Requirements Most Programs Share?

Beyond the universal requirements, here are the most frequent additional conditions that determine eligibility:

Old Toilet Replacement Requirement

Most programs require you to be replacing an existing toilet, not simply adding one. Many specify the old toilet must have been a 1.6 GPF or higher model (some require 3.5 GPF or older). Programs in the West often specifically target pre-1992 toilets (the year 1.6 GPF became a national code minimum) that still use 3.5 or 5.0 GPF. Some utilities require you to destroy the old toilet by breaking the bowl -- and ask for a photo as proof -- to prevent the high-flush unit from being reinstalled or resold.

Proof of Purchase Documentation

A dated, itemized receipt is required by virtually every program. The receipt must show the model name or number clearly enough for the program administrator to verify WaterSense eligibility. Credit card statements are typically not accepted as standalone proof -- you need the itemized receipt. If you lose a receipt, a reprint from the retailer often works but must be obtained before submission.

Installation Verification

Many programs require a photograph of the installed toilet showing the toilet in place in the bathroom. Some programs also require a photo of the toilet's WaterSense label (often found on the tank or paperwork) or the model number plate inside the tank. A small number of programs (particularly in New York City and some California agencies) require that installation was done by a licensed plumber, which adds labor cost but may also come with a separate labor rebate.

Application Window

Most programs specify that rebate applications must be submitted within 90 to 180 days of the purchase date. Late applications are rarely accepted. If you are planning a bathroom renovation, submit the rebate paperwork as soon as the toilet is installed, not at the end of the overall project.

Limits Per Address or Account

Almost all programs cap the number of qualifying toilets per residential address, typically between 2 and 6 units. Rental properties and multi-family buildings often have different (sometimes higher) limits and may need to apply through a commercial rebate track.

How Do You Apply for a Toilet Rebate Step by Step?

Here is the complete process mapped out in detail:

Step 1 -- Research Before You Buy

Use the EPA Rebate Finder and call your utility as outlined above. Confirm the program is currently accepting applications (funds run out mid-year in popular markets), note the exact GPF requirement, and save the program's required documentation checklist.

Step 2 -- Choose a Qualifying Toilet

Select a model confirmed in the EPA WaterSense product database. Print or screenshot the EPA listing showing the model number and certification date. Keep this with your documentation. For the best combination of rebate eligibility and performance, the TOTO Drake II, TOTO UltraMax II, American Standard Champion 4 HET, and Kohler Cimarron are among the most widely available and reliably certified options. If you are also interested in overall flush quality, the best flushing toilets guide covers MaP scores and performance data in detail.

Step 3 -- Purchase and Document Everything

Keep the original itemized receipt. Photograph the toilet box (showing model number), the WaterSense label, and the old toilet still in place before removal. Photograph the new toilet installed and operational. Some programs also want a photo of the old toilet with the bowl broken or disposed. Store all photos timestamped if your phone supports it.

Step 4 -- Complete the Application

Most programs now use an online portal. Create an account if required (usually just your utility account number and service address). Fill in model number, purchase date, retailer name, and upload all required documentation. Double-check that the model number you enter exactly matches the number on the receipt and the EPA database -- small discrepancies cause rejection.

Step 5 -- Follow Up

Keep a copy of your submitted application and confirmation number. If you have not received a response within the program's stated processing window (usually 6 to 12 weeks), follow up by phone. Rebate administrators process high volumes and applications sometimes get stuck in document review without automatic notification.

Step 6 -- Combine with Other Incentives

After submitting your utility rebate, check whether your state income tax allows a deduction or credit for water conservation improvements. Some states, including Oregon and California, have had tax provisions for qualifying fixtures. These are separate from utility rebates and do not affect rebate eligibility.

Special Situations: Rental Properties and Commercial Buildings

Landlords replacing toilets in rental units can typically apply for rebates, but the applicant must be the account holder (the property owner, not the tenant). Commercial rebate programs for office buildings, hotels, and multi-family properties often have much higher per-unit limits and higher rebate amounts because the water savings scale. If you own a building with 10 or more units, contact your utility's commercial conservation desk rather than the residential line -- commercial programs are structured differently and often provide project-level assistance.

For a deeper look at which specific models deliver the best water efficiency at each GPF rating, see our guide to best low flow toilets and the breakdown of EPA WaterSense certified toilets.

Free Toilet Programs: When the Rebate Covers the Full Cost

Several utilities -- particularly in California and the Southwest -- go beyond rebates and offer full toilet replacement at no cost to qualifying households. Programs like LADWP's Water Savings Assistance Program and some Metropolitan Water District local programs deliver and install WaterSense toilets free of charge for income-qualified customers. Contact your utility and specifically ask about "low-income water conservation programs" or "free fixture replacement programs." These are separate from standard rebates and have different income verification requirements.

Texas also runs the Texas Water Development Board's WaterIQ program, which provides resources and connects homeowners with utility efficiency programs statewide. Arizona's Water -- Use It Wisely campaign aggregates local rebate programs across the state's municipalities. The Alliance for Water Efficiency's WaterSmart Homes program similarly aggregates programs regionally.

MaP Scores and Why They Matter for Rebate Decisions

One concern homeowners raise when selecting a rebate-eligible toilet is whether the water-efficient model will flush as powerfully as their old 3.5 GPF unit. MaP (Maximum Performance) flush testing, conducted by an independent laboratory and published at map-testing.com, measures how many grams of solid waste a toilet can clear in a single flush. Scores range from 0 to 1,000 grams.

The majority of popular WaterSense models score well above the minimum threshold:

• TOTO Drake II (1.28 GPF): 1,000 grams (MaP score)
• TOTO UltraMax II (1.28 GPF): 1,000 grams
• American Standard Champion 4 HET (1.28 GPF): 1,000 grams
• Kohler Cimarron (1.28 GPF): 800 grams
• Kohler Highline (1.28 GPF): 800 grams
• American Standard Cadet 3 (1.28 GPF): 800 grams
• TOTO Aquia IV (0.8/1.0 GPF): 800 grams
• Woodbridge T-0001 (1.28 GPF): 800 grams
• Gerber Viper (1.28 GPF): 1,000 grams

A MaP score of 800 grams or above is considered very good for residential use. Scores at 1,000 grams (the maximum tested) essentially guarantee no clog issues under normal household use. Replacing a 3.5 GPF toilet from the 1980s with a modern 1.28 GPF model scoring 1,000 grams on MaP testing is an upgrade in both efficiency and performance, not just efficiency alone. For more detail on MaP scoring methodology, see our MaP score guide.

Long-Term Savings Beyond the Rebate

A rebate is a one-time benefit. The annual water savings of replacing an old high-flush toilet compound over the life of the fixture. At national average water rates of approximately $1.50 per thousand gallons (rates vary significantly by city), replacing a 3.5 GPF toilet with a 1.28 GPF model saves roughly $26 to $40 per year in water costs. Over a 10 to 20-year fixture lifespan, that adds up to $260 to $800 in cumulative savings beyond the initial rebate.

In water-stressed cities where rates are higher -- San Diego, where rates can exceed $7 per thousand gallons, or New York City, where combined water and sewer rates average $12 per thousand gallons -- the annual savings from a toilet replacement are correspondingly larger. For homeowners in high-rate markets, the payback period for a new efficient toilet is often under two years even without a rebate, and with a rebate the economics become even more favorable immediately.

For households on septic systems, lower-flush toilets also extend the interval between septic pumping by reducing the total volume of water entering the tank each day, an additional financial benefit that rebate programs do not typically quantify. See our guide to best toilets for septic systems for more on this topic.
