Best Water Saving Toilets of 2026

The Drake II is the toilet that ends the argument that saving water means a weak flush, reaching the full 1000 gram MaP score at just 1.28 gallons, the best water-to-clearance ratio you can buy in any single-flush toilet.

The Drake II uses TOTO's Double Cyclone flush, which sends the 1.28 gallon tank through two angled nozzles instead of a ring of small rim holes, so the water swirls around the bowl and feeds a strong siphon. That centrifugal action lets it hit the maximum 1000 gram MaP score at only 1.28 gallons, which means it clears a heavy household load in a single push and you never reach for the handle a second time. Because every double flush erases a low-water toilet's savings, that combination is exactly what makes the Drake II the best water saver on the market.

It pairs the flush with a fully glazed CeFiONtect trapway, so waste passes cleanly and the bowl stays cleaner between cleanings, which also reduces the urge to reflush. Owner reviews praise its reliability and consistent flush across years of use. The body is a comfort-height elongated two-piece, so there is a tank-to-bowl seam to wipe and the base is not skirted. For most households that want the deepest water savings with zero compromise on flush strength, this is the default choice and a frequent pick among the best low flow toilets at 1.28 GPF and under.

The Aquia IV is the pick when you want to push water use below even 1.28 gallons, a dual flush toilet whose 0.8 gallon light flush handles the many liquid uses in a day and drops the household average to the lowest of any model here.

The Aquia IV uses TOTO's Dynamax Tornado flush, which feeds water through two angled nozzles to create a swirling rinse rather than dumping it down the front of the bowl. That motion lets the 1.28 gallon full flush reach an 800 gram MaP score, while the 0.8 gallon partial flush is among the lowest light flushes you can buy. Because most daily uses in a normal home are liquid only and trigger the small flush, the Aquia IV's average gallons per flush in real use lands well under any single-flush model on this list, which is why it earns the lowest daily water draw here.

It is a fully skirted two-piece with smooth sides and no exposed trapway contours, so the base wipes clean in one pass, and the CeFiONtect glaze keeps the bowl cleaner between wipes. The tradeoffs are a full-flush MaP of 800 grams that trails the 1000 gram leaders and the small habit of choosing the right button. For the most water saved per day in a normal household, it is the standout, and it suits the same buyer as our roundup of the best eco friendly toilets for a greener bathroom.

The Cimarron pairs a strong 1.28 gallon flush with a more refined look than most value toilets, hitting the full 1000 gram MaP score at a friendlier price with the easiest nationwide parts support of any pick here.

The Cimarron uses Kohler's Class Five canister flush, which lifts a canister seal to release the whole tank through a large 3.25 inch opening rather than a small flapper. That fast, full release gives it the punch to reach a 1000 gram MaP score at 1.28 gallons, so it clears the bowl in one push and the water savings hold. The canister design also tends to seal better over time than a standard flapper valve, which matters for water saving, because a worn flapper is the most common silent leak that wastes hundreds of gallons and quietly undoes the savings.

It is a comfort-height elongated two-piece with the WaterSense label, and because Kohler is sold in every big-box store, replacement seals and the canister are easy to find locally for years. The canister flush is slightly more audible than a TOTO siphon, and the stock seat and trip lever feel basic, but for buyers who want dependable 1000 gram water saving and a cleaner look without a premium price, the Cimarron is the value standout.

The UltraMax II takes the Drake II's water-efficient Double Cyclone flush and puts it in a sleek one-piece body, delivering the same 1000 gram clearing at 1.28 gallons with no tank-to-bowl seam to scrub.

The UltraMax II carries the same 1000 gram MaP score at the same 1.28 gallons as the Drake II, so you give up nothing on water savings or flush strength while gaining a seamless silhouette. It uses TOTO's CeFiONtect glaze, which helps waste and mineral buildup slide away, keeping the bowl clear and reducing nuisance reflushing that would otherwise waste water. It is WaterSense certified and a frequent favorite where easy cleaning matters as much as efficiency.

This is the pick for buyers who want the deepest single-flush water savings, a low-maintenance bowl and a clean one-piece look in one package. It costs more than the two-piece Drake II, and as a one-piece it is heavy, so a helper is wise during installation. Owner reviews rate it among the most reliable efficient toilets available, with the smooth body cited again and again as a reason it stays cleaner between cleanings.

The Cadet 3 is American Standard's reliable everyday toilet, and it earns its place by clearing the bowl hard at just 1.28 gallons with a wide flush valve and a clog-resistant glazed trapway, all WaterSense certified.

The Cadet 3 uses a siphon flush fed by a wide 3 inch flush valve, larger than the 2 inch valves on many budget toilets, which gives a faster, stronger pull. That combination reaches the full 1000 gram MaP score at 1.28 gallons, so it saves water while clearing heavy loads in one flush. The bowl has an EverClean antimicrobial surface that helps slow stains and odors between cleanings, which keeps the bowl looking clear and reduces the nuisance reflushing that wastes water.

It is a straightforward comfort-height two-piece without the premium glaze of a TOTO, but the ten-year limited warranty is among the longest in the category and signals confidence in the build. Owner reviews praise its dependable flush and easy parts availability. For a dependable water saving flush at a sensible price, it is an easy recommendation for most bathrooms, and it carries over from our list of toilets that never clog.

The T-0019 is the sleek skirted dual flush one-piece that built Woodbridge's reputation, offering a designer body, real dual-flush water savings and a top-tier full flush at a price well below the premium brands.

The T-0019 is a fully skirted one-piece with a dual-flush button plate, so the trapway hides behind a smooth side panel and the seamless body wipes clean in one pass. It uses a 1.0 gallon partial flush and a 1.28 gallon full flush, and the full flush posts a strong 1000 gram MaP score, so it trims daily water use on the many liquid flushes while still clearing heavy loads in one push. The soft-close seat is included, a genuine bonus at this price.

Owner reviews run deep and consistently praise a clean flush, a quiet refill and the upscale skirted shape. The tradeoff is that Woodbridge parts are less universal than TOTO or Kohler, so a repair may mean ordering a specific dual flush mechanism, and the brand sells under several similar model numbers, so confirm the exact number before ordering. For designer styling with real dual-flush water savings and a top full flush, it is a standout, and it appears again in our guide to the best EPA WaterSense certified toilets.

The St. Tropez is the pick for the lowest possible water draw with modern styling, a sleek skirted one-piece whose dual flush light mode sips just 0.8 gallons at a price well below the premium brands.

The St. Tropez pairs a 0.8 gallon partial flush, among the lowest available anywhere, with a 1.28 gallon full flush that reaches an 800 gram MaP score, so it clears solids cleanly without pressing the button twice. Its appeal is the combination of that very low water use with a contemporary low-profile design and a fully skirted base that wipes clean in seconds. The soft-close seat and the button plate are included, which keeps the package complete out of the box.

Swiss Madison is a newer brand than the established names, so its long-term reliability record and parts depth are not as deep, and a few owners note the compact tank can refill a little slowly between flushes. Owner reviews are broadly positive on looks and flush strength, with the usual caution to confirm the bolt-down and supply connection on install. For a water-minded buyer who also wants a modern look for less, it is a strong value.

The Santa Rosa brings a strong 1000 gram water saving flush to a compact one-piece body, fitting a shorter footprint into a small bathroom while keeping a comfortable compact-elongated seat.

The Santa Rosa uses Kohler's AquaPiston canister flush, which releases water around the full 360 degrees of the bowl rather than from one point, so the 1.28 gallon tank scours the bowl evenly and reaches the 1000 gram MaP score. That even rinse clears the bowl in one push, securing the water savings, and the canister design seals more reliably over time than a flapper, which prevents the silent tank leaks that waste water. It is WaterSense certified.

The one-piece skirted design hides the trapway contours and wipes clean in seconds, which suits a small bathroom where every surface is close to hand, and Kohler parts are easy to find locally for years. The canister flush is slightly louder than a siphon, and as a one-piece it is heavy to set, but for a space-saving toilet that still saves water and flushes hard, the Santa Rosa is the standout, and it features in our guide to the best eco friendly toilets for a greener bathroom.

The Viper is Gerber's value water saver, a plumber favorite that delivers genuine 1.28 gallon savings and dependable clearing for one of the lowest prices in the category.

Despite its low price, the Viper posts an 800 gram MaP score on its 1.28 gallon flush with a wide trapway, so it resists clogs about as well as toilets that cost far more, while staying at the WaterSense 1.28 gallon level. For a hardworking or rental bathroom where water savings are the goal and budget is tight, that combination of strength and value is hard to beat, and the 800 gram score is enough to clear a normal household load in one flush.

Gerber is a long-time plumber favorite because its toilets are dependable and inexpensive to service, and the simple two-piece design installs with standard fittings. The 800 gram MaP is below the 1000 gram leaders, so it is not the strongest flush here, and the styling is plain with an exposed trapway. For raw water-saving value per dollar across several bathrooms, though, the Viper is the smart-money contractor choice, much like its siblings in our guide to the best low flow toilets at 1.28 GPF and under.
