Best Toilets (2026): 7 Picks Compared by Flush and Fit

We may earn commission from links on this page. Lead-form submissions are forwarded to local inspector partners. How we research and review.

The best toilet for a given bathroom is the one that fits the drain you already have, flushes reliably on your water pressure, and does not waste water doing it. Rough-in distance, gallons per flush, bowl shape and seat height matter far more than the finish or the marketing name on the box. This guide sorts current Amazon toilet listings by those numbers, flags what each listing leaves out, and explains how to measure before you order a 100-pound piece of china that ships by freight.

How we compared: we compared 8 current Amazon toilet listings on what each one states: flush volume, flush type, rough-in, bowl shape, seat height, what comes in the box and the parts it uses. The search also returned toilet paper and bidet attachments, which we set aside. We did not lab-test or install any of these toilets. Prices, stock and shipping terms change, so confirm the current listing before you buy.

The 7 picks, compared listing by listing

1. Gerber Maxwell Crest GRS48310 — Best Overall Two-Piece Toilet

Best overall

Why we like it

• Single 1.28 gpf flush matches EPA’s efficiency benchmark
• Uses Fluidmaster 400A fill and 3 in. flush valves
• Soft-close elongated seat comes in the box
• Install kit includes the wax ring
• Glazed trapway to help waste move through

Gerber GRS48310 — two-piece, elongated, 1.28 gpf, Fluidmaster 400A + 3 in. flush valve, seat and wax ring included

The Only 1.28-Gallon Toilet on the Shelf, Built on Off-the-Shelf Parts

Of the 8 toilets we compared, this is the only one rated at exactly 1.28 gallons per flush. Five listings use a 1.1/1.6 dual flush, one runs at 1.0 gallon and the TOTO Drake sits at the 1.6 federal maximum. EPA’s WaterSense program describes 1.28 gallons as the line that newer toilets meet while using 20 percent less water than the 1.6 federal standard. The Gerber listing does not claim the WaterSense label itself, so check EPA’s product search if a utility rebate depends on it.

The bigger reason it leads is serviceability. It is the only listing on this shelf that names the brand and model of both its fill valve and flush valve. Fluidmaster parts are stocked at nearly every hardware store, so replacing a worn flapper years from now is a ten-minute job, not a hunt for a proprietary part.

What it does not state matters too: there is no rough-in figure and no seat height in the listing. Most two-piece toilets of this type are 12 in. rough-in, but measure your floor and confirm with the seller before ordering.

2. TOTO Drake CST776CSFG — Best for Low Water Pressure

Best for low-pressure homes

Why we like it

• Only listing that states a minimum water pressure
• Wide 3 in. flush valve with siphon jet bowl
• CEFIONTECT glaze to keep waste from sticking
• Universal Height can meet the ADA seat requirement

TOTO Drake CST776CSFG — two-piece, elongated, 1.6 gpf, Tornado Flush, 12 in. rough-in, 8 psi min., left-hand lever, no seat

The Only Listing That Tells You How Little Pressure It Needs

None of the other 7 toilet listings state a minimum supply pressure. The Drake listing says it works down to 8 psi flowing, which is useful for homes on a well, an older galvanized supply or a long run to a second-floor bath. One other listing, the Casta Diva CD-W001, says it flushes well in low-pressure settings, but it does not give a number.

It is also the only toilet here at the full 1.6 gallon federal limit. Some buyers want that extra volume for long, flat drain runs or older cast-iron lines; others would rather save the water. The listing also names a left-hand trip lever, a 3 in. flush valve and a 2-1/8 in. trap seal, which are the kind of details a plumber looks for.

Budget for the extras. This is the only listing here that clearly says the seat is sold separately, and it adds that the wax ring, flange bolts and supply line are sold separately. If you are pairing it with a bidet seat later, our best bidet comparison covers the add-on side.

3. Casta Diva CD-W001 — Best for Lowest Water Use

Best water saver

Why we like it

• 1.0 gallon flush, the lowest on this shelf
• Air-pressure assist with no electricity required
• Hands-free foot-kick flush plus a side button
• 17.2 in. ADA comfort seat height
• Seat, wax ring and hardware included

Casta Diva CD-W001 — one-piece, 1.0 gpf air-assisted, foot-kick + button, 17.2 in. seat, 12 in. rough-in, cUPC

One Gallon per Flush, With a Foot Pedal

Every other toilet in our comparison uses at least 1.1 gallons on its light flush and 1.28 or more on a full flush. This listing claims a single 1.0 gallon flush boosted by a non-electric air-pressure system, and it says the design meets EPA WaterSense criteria. It also states a MaP score of 1000 g, one of three listings here that cite a MaP number directly.

It is the only toilet on the shelf with a foot-kick flush. That makes it a practical choice for a household member with limited hand strength, or anyone who would rather not touch a handle. At 19.3 in. tall with a built-in tank, it also has the lowest profile of the group, which can help under a window or a low shelf.

The listing does not give a weight or explain how to service the air-assist mechanism. Pressure-assist parts are less common than standard flappers, so ask the seller where replacement parts come from before you commit.

4. HOROW T0338W — Best When You Need a 10-Inch Rough-In

Best for 10 in. rough-in

Why we like it

• Only listing offering both 10 and 12 in. versions
• Compact 26.6 in. depth with an elongated bowl
• Fully glazed 2 in. trapway and siphon flush
• Large side openings for the floor bolts

HOROW T0338W — one-piece, skirted, 1.1/1.6 gpf, MaP 1000 g, 17.3 in. seat, 10 or 12 in. rough-in, 1-yr warranty

The Only Listing That Addresses Short Rough-Ins

Six of the 8 toilet listings state a 12 in. rough-in, and two do not state one at all. HOROW is the only brand here that says it sells the same toilet in a 10 in. version. That matters in older homes and some condos where the drain sits closer to the wall; a 12 in. toilet simply will not fit there. Our toilet rough-in guide shows how to measure from the finished wall to the center of the flange bolts.

Beyond the rough-in, it is a typical one-piece dual flush: 1.1 gallons for liquids, 1.6 for solids, and a stated MaP score of 1000 g. The fully glazed 2 in. trapway is one of the few trapway sizes given on this shelf.

Make sure you select the 10 in. variant on the listing page if that is what you need; the default shown on this listing is the 12 in. size. The listing does not say whether a wax ring is included.

5. Casta Diva CD-T005 — Best Comfort-Height Dual Flush

Best comfort-height dual flush

Why we like it

• 17 in. ADA comfort seat height
• Dual flush with a stated MaP 1000 g score
• Pre-installed fill and flush valves
• Wax seal and all hardware in the box

Casta Diva CD-T005 — one-piece, skirted, 1.1/1.6 gpf, MaP 1000 g, 17 in. seat, 12 in. rough-in, cUPC

A Complete Kit for a Taller Seat

Four listings here give a specific comfort or chair seat height of 17 in. or more, and this one pairs that height with one of the most complete boxes on the shelf: pre-installed fill and flush valves, a slow-close seat and lid, a wax seal and floor hardware. Only 2 of the 8 listings name cUPC, the plumbing certification mark, and both are Casta Diva models, this one included.

Like the CD-W001, it says it meets EPA WaterSense criteria. It reaches that through the dual flush rather than a single low-volume flush. EPA notes that a dual-flush WaterSense toilet saves the most when you actually use the reduced flush for liquid waste, so it helps to show everyone in the house which button is which.

The listing does not give a weight or a warranty length beyond 1-year limited customer service.

6. DeerValley Compact DV-1F52812 — Best for Small Bathrooms

Best for small bathrooms

Why we like it

• Shallowest toilet on the shelf at 24.6 in.
• Only round bowl among the listings
• Wax ring, bolts and wrench included
• States a 250 lb seating capacity

DeerValley DV-1F52812 — one-piece, round bowl, 1.1/1.6 gpf, 12 in. rough-in, 24.6 in. deep, 78 lb, 12-mo warranty

The Only Round Bowl, and the Shortest Projection

Seven of the 8 toilets here use an elongated bowl. This DeerValley is the only round-bowl model, and at roughly 24.6 in. deep it projects about 2 in. less into the room than the next-shortest listing. In a powder room or a hall bath where the door swings close to the bowl, those inches decide whether the door clears your knees.

It is also the lightest one-piece toilet whose listing gives a weight, at 78 lb. That makes a one-person carry possible, though two people setting it on the wax ring is still the safer plan. The listing says it seats up to 250 lb, the only capacity figure on the shelf.

The trade-off is comfort. Round bowls are shorter front to back and many adults find elongated bowls more comfortable, and this listing describes a standard rather than comfort seat height. It does not state a MaP score.

7. Swiss Madison St. Tropez SM-1T254HB — Best Modern Look

Best modern look

Why we like it

• Black hardware against white china
• Comfort height stated as 17 to 19 in.
• Dual Vortex flush at 1.1 or 1.6 gpf
• Scratch-resistant, non-porous ceramic

Swiss Madison SM-1T254HB — one-piece, elongated, 1.1/1.6 gpf, 12 in. rough-in, black hardware, 108.5 lb

The Design Pick, and the Heaviest Box

This is the only listing whose finish choice is black flush hardware, which suits a matte-black faucet and shower trim. Function is similar to the other dual-flush one-piece models: 1.1 and 1.6 gallon flushes, a 12 in. rough-in and an elongated bowl.

At 108.5 lb it is the heaviest toilet with a stated weight, about 30 lb more than the DeerValley compact. Plan a two-person carry and protect the finished floor. The listing is also thin on what is in the box: it does not mention a seat, wax ring, bolts or a MaP score, so treat those as purchases until the seller confirms otherwise.

How to read toilet specs before you buy

Rough-in comes first

Rough-in is the distance from the finished wall behind the toilet to the center of the drain, usually read off the two flange bolts. Most homes use 12 in., but 10 in. and 14 in. exist, especially in older houses and remodels. Measure from the wall itself, not from the baseboard. A toilet with the wrong rough-in will either hit the wall or leave a gap that looks wrong and stresses the tank. Six of our 8 listings say 12 in.; only one offers 10 in.

Gallons per flush and the WaterSense label

Federal rules cap new toilets at 1.6 gallons per flush. EPA’s WaterSense label goes further, recognizing toilets at 1.28 gallons or less that are independently certified for both efficiency and flushing performance. EPA says replacing old toilets with labeled models can cut toilet water use by 20 to 60 percent, close to 13,000 gallons a year for an average family. Two listings here claim to meet WaterSense criteria; only a certified model can carry the label, so confirm it in EPA’s WaterSense product search. EPA is also revising how dual-flush toilets qualify, which is another reason to check the current list rather than rely on a listing.

MaP scores

MaP (Maximum Performance) testing reports how many grams of test media a toilet clears in one flush. Three listings here state a MaP figure of 1000 g, and one more states 1,000 grams of flushing capacity without calling it MaP. Treat a MaP claim as useful only when the listing states it; a missing score does not mean a weak flush, just an untested claim.

One-piece vs two-piece

One-piece toilets fuse the tank and bowl, so there is no tank-to-bowl gasket to leak and fewer crevices to clean. Six of our listings are one-piece. Two-piece models break into two lighter pieces for carrying, and replacement parts tend to be standard. Either type works; the choice is mostly cleaning versus handling.

Seat height and bowl shape

Standard toilets put the seat around 15 in. off the floor; comfort or chair height adds about 2 in., which helps taller adults and anyone with knee or hip trouble. Small children may find it harder. Elongated bowls are more comfortable for most adults but add depth; round bowls save space. For more height without a new toilet, a raised toilet seat is the low-cost option.

Installation, shipping and the parts that fail

Toilets bought online usually arrive by freight on a pallet or in a heavy carton. Open the box and check the china for cracks before you sign, because a hairline crack in a tank can leak slowly for weeks. Then plan the swap:

• Close the toilet shut-off valve, flush and sponge the tank dry. If the old multi-turn valve will not seal, replace it before you go any further.
• Use a new toilet wax ring every time a toilet comes up. Five listings here say one is included; the TOTO says to buy it separately.
• Fit a new braided supply line rather than reusing an old plastic one. One DeerValley listing includes an adapter for 1/2 in. supply lines.
• Check the flange. A cracked or low flange is the usual cause of rocking and leaks at the base, and it must be fixed before the new bowl goes down.

Our step-by-step toilet installation guide walks through setting the bowl, tightening bolts evenly and testing for leaks. After install, EPA suggests a simple leak check: put a few drops of food coloring in the tank and see whether color shows up in the bowl after 10 minutes. EPA notes that most toilet leaks come from worn flappers, and that household leaks can waste around 180 gallons a week.

Front Range water and toilet upkeep

Many Front Range communities have moderately hard water, and mineral scale is what slowly wears out fill valves, flappers and the small rim jets under the bowl. A glazed trapway and a smooth bowl coating help, but scale still forms. Every year or two, lift the tank lid and look for a fill valve that hisses, a flapper that has gone soft or stiff, and white crust around the jets. Homes on a septic system should also keep flushes limited to human waste and toilet paper; EPA’s septic guidance lists wipes, grease and household chemicals among the things never to flush.

Low-water-use toilets are a good match for the region’s water-conscious utilities, but they need a sound drain line. If an older home has a sagging or root-damaged sewer lateral, a 1.0 or 1.1 gallon flush may not carry waste as far as an old 3.5 gallon tank once did. Gurgling, slow flushes or repeat clogs after a new toilet usually point downstream, not at the fixture.

When a new toilet is not the fix

A new toilet fixes cracked china, constant running and poor flushing from an outdated bowl. It does not fix a rotted subfloor, a broken flange, a sewer line full of roots or a vent problem. Signs that call for a plumber or an inspection instead:

• Soft or stained flooring around the base, which can mean a long-term leak. Our guide to a toilet leaking at the base covers the causes.
• Several drains backing up at once, or water coming up in a tub when the toilet flushes.
• Sewer odor in the bathroom even with a good wax seal.
