Best Rated Toilets: Top Picks and a No-Nonsense Buying Guide

A bad toilet announces itself within a week — clogs, ghost flushing, a seat that wobbles like a dinghy. Picking from the best rated toilets on the market is less about chasing the trendiest model and more about matching flush technology, bowl shape, and rough-in to your bathroom. After installing more than 300 toilets across remodels and new builds, four models keep showing up on my reorder list because they perform year after year. Here is what works and why.

What Makes a Toilet Rate Well

Three benchmarks separate good from great. First, MaP (Maximum Performance) testing: anything scoring 800 grams or higher clears real-world waste reliably. Second, Gallons Per Flush — modern WaterSense models use 1.28 GPF or less, with the best dual-flush units averaging under a gallon. Third, comfort: 17-inch bowl height (often called Comfort Height or Right Height) is dramatically easier on knees than the old 14.5-inch standard.

Rough-in (the distance from the wall to the closet bolts) almost always measures 12 inches in US homes, but pre-1965 homes often have 10-inch or 14-inch rough-ins. Measure before you buy.

Toto Drake II: The Contractor’s Pick

The Toto Drake II is the toilet I install in my own clients’ primary baths. It pairs Toto’s Double Cyclone flush with a 3-inch valve and a 2-1/8-inch glazed trapway — so it moves water fast and resists streaking. MaP score: 800+. Real-world clog rate: vanishingly low.

Expect to pay $400-$520 for the Drake II two-piece in cotton white. Elongated bowl, universal height, and a CeFiONtect glaze that genuinely keeps the bowl cleaner between scrubs. The only downside is the seat is sold separately on most configurations — budget another $40-$80 for the matching SoftClose lid.

Kohler Cimarron: Best Mid-Price All-Rounder

The Kohler Cimarron with Comfort Height and AquaPiston canister flush has been a go-to since 2009. Its valve has a 90-degree drop that prevents the leaks common in flapper-style toilets, and the bowl design clears MaP testing at 1,000 grams. At $300-$400, it undercuts the Drake while delivering similar real-world performance.

Kohler’s parts availability is the quiet selling point. Walk into any Home Depot or Lowes and you can find Cimarron flush valves, fill valves, and seats in stock — important when a tank component fails on a Sunday afternoon.

American Standard Champion 4: Best for Large Households

The American Standard Champion 4 is the brute force option. Its 4-inch flush valve is roughly twice the size of a standard valve, and the Champion claims to flush a bucket of golf balls in a single push. MaP score is 1,000 grams, the highest in this guide.

If you have teenagers, a frequent guest bath, or a household that simply uses a lot of paper, this is the model. Pricing runs $320-$450 depending on retailer. The flush is loud — louder than the Drake or Cimarron — so it is not the right pick for a master bath sharing a wall with a bedroom.

Niagara Stealth: Best for Water Savings

The Niagara Stealth uses just 0.8 gallons per flush, the lowest of any major-brand toilet, and it pulls it off using vacuum-assist technology rather than a weak gravity flush. The tank pressurizes briefly between flushes, then releases water with a powerful sucking action. Result: full bowl clearance on under a gallon.

At $250-$350, the Stealth is the cheapest unit on this list. It also qualifies for water rebates in California, Texas, Arizona, and Nevada — sometimes returning $100 or more after install. Drawbacks: parts are less common at big-box stores, and the flush sound is unusual (a quiet whoosh rather than a swirl).

One-Piece Versus Two-Piece

One-piece toilets like the Kohler Santa Rosa look sleeker and clean faster — there is no seam between tank and bowl to harbor grime. They cost $100-$300 more than the equivalent two-piece and are heavier to maneuver during install (often 90+ pounds). Two-piece toilets are easier to carry up stairs and ship in standard residential packaging.

If aesthetics drive your remodel, go one-piece. If you live in a third-floor walk-up or want easier servicing, two-piece is the practical choice.

Elongated Versus Round Front

Elongated bowls add 2 inches of bowl length and are universally more comfortable. Round-front bowls only make sense in tight powder rooms where door swing or vanity placement steals floor space. Code in most US jurisdictions requires 21 inches of clear space in front of a toilet — an elongated bowl with a 31-inch rough-out total still meets this in most layouts.

Bidet Seat Compatibility

If you plan to add a bidet seat now or later, confirm the toilet bowl shape (elongated D-shape works with virtually all bidet brands; some traditional Kohler shapes do not) and that the seat post spacing matches the 5.5-inch standard. Toto Washlets, Brondell Swash, and Kohler PureWarmth all fit the four toilets in this guide.

Installation and Hidden Costs

• Wax ring or waxless seal — $5-$15. Replace every install, never reuse.
• New supply line — $8-$15 for a quality braided stainless line.
• Closet bolts and caps — $4-$8.
• Plumber labor — $150-$350 for a swap, $400-$700 if the flange or subfloor is rotten.
• Disposal of old toilet — $25-$60 if your trash service charges extra for porcelain.

Always check the floor flange before committing. A flange sitting below the finished floor needs a Sani-Seal or extender — installing a new toilet on a low flange is the leading cause of leaks within the first year.

Final Recommendation

For most homeowners, the Kohler Cimarron offers the best balance of flush power, comfort, parts availability, and price. Move up to the Toto Drake II for primary baths and master suites. Choose the American Standard Champion 4 if clogs are a recurring frustration, and the Niagara Stealth when water bills or rebates drive the math. All four show up consistently on best rated toilets lists for good reason — they simply work.
