Best Flushing Toilets by GPF, Valve Size and Height

The best flushing toilets home depot shoppers compare usually lose to a part, and the Fluidmaster 400AKRP10 Universal Toilet Repair Kit is the pick I'd start with: an 8 oz kit with a 5 year warranty that replaces the fill valve, flapper and handle on most 2-inch flush valve toilets. If you want a whole fixture, the Gerber Maxwell Select brings a 1.28 and 1.0 gpf split flush in a two-piece body. Most buyers here compare bowl shape and brand name. Neither one decides how hard the water leaves the tank.

Best flushing toilets home depot picks at a glance

How these best flushing toilets home depot picks map to buyers

I built this list around four people, not four brands. That is the only honest way to compare an 8 oz repair kit against a 103.6 lb ceramic bowl.

1. The person whose current toilet got weak. Nothing about the bowl changed. The flapper aged. The Fluidmaster kit is aimed squarely here.
2. The person replacing one broken half. A cracked tank on an otherwise fine bowl. The American Standard 4000101.020 tank exists for exactly that, and only that.
3. The person doing a full swap. New fixture, new seat, new flush volume. Gerber, DeerValley and PeacefulHues are the three whole toilets in this set.
4. The person with an unusual install. An RV, a camper, a bathroom where the handle is a hygiene complaint. SEAFLO and KERDE cover those edges.

Note the word "partial" hanging over this whole comparison: a search for best flushing toilets home depot returns Amazon listings, and nothing in this data confirms any of these seven sits on a Home Depot shelf. Treat the retailer part of that phrase as your own errand. Cross-check the model numbers, which I've printed for every pick, against whichever store you actually want to buy from. What I can compare is the published flush hardware, and that is where the real difference lives.

Why does valve size decide flush power?

Flush strength is a function of how fast the tank empties. A wider flush valve dumps the same gallon faster, and speed is what carries waste through the trapway.

That is why the specification I keep coming back to in these best flushing toilets home depot listings is the valve opening. The Fluidmaster kit is built for a 2 in flush valve. The American Standard tank includes a 3 in flush valve. Same water, different exit. Gerber and DeerValley describe canister and rimless designs instead of stating an opening diameter, which is a claim about geometry rather than a number you can measure at the store.

A short glossary, because these words get used loosely:

• GPF is gallons per flush. 1.28 gpf is the current high-efficiency figure, and four of these picks cite it.
• Dual flush is two volumes on one valve. Gerber lists 1.28 and 1.0 gpf; DeerValley lists 1 and 1.28 GPF.
• Siphonic describes a trapway that pulls, which is what PeacefulHues claims at 1.28 gpf.
• Gravity flush is what SEAFLO uses, with a tri-directional rinse claim and a foot pedal instead of a lever.

Here's the trick with a weak flush: check the flapper before you blame the gallons. A flapper that closes early cuts the effective volume without changing the sticker on the tank. That failure looks exactly like a badly designed toilet, and it costs an 8 oz part to fix.

1. Fluidmaster 400AKRP10 Universal Toilet Repair Kit — Best overall

The cheapest pick here is the one most likely to solve the actual problem, because a weak flush is usually worn tank hardware rather than a bad bowl.

Best for: an existing toilet that flushes weakly or runs Skip it if: your flush valve opening is 3 inches

This kit does three jobs at once, which is what separates it from a single flapper. Fluidmaster says it replaces inefficient fill and flush valves, leaky flappers and broken handles in one go, and the fill valve adjusts from 9 to 14 inches to suit different tank depths. The listed fit is most 2-inch flush valve toilets, ideal for 1.6 to 3.5 gallons per flush models or larger. That covers a very wide slice of American bathrooms installed since the early nineties.

It is also the only pick in this set with a published warranty length attached to a specific term: 5 Year. SEAFLO cites 4 years for its RV unit, and American Standard mentions a limited lifetime warranty on ceramics, which is a different promise about a different material. The kit weighs 8 oz and measures 2.91 x 1.69 in on its listed dimensions, so shipping and storage are trivial.

The trade-off against every whole fixture below is obvious. This does not change your bowl shape, your seat height or your rough-in. If the toilet you own is the wrong height or the wrong size for the room, no valve fixes that. Buy this to restore performance, not to redesign a bathroom. Fluidmaster claims a 10 minute install, and that's the claim I'd verify against your own shutoff valve before you start.

Pros:

• Cheapest of the seven picks here
• 5 Year warranty, the longest stated term in this set
• Fill valve adjusts 9 to 14 inches
• Replaces valve, flapper and handle together
• 8 oz, so no freight handling

Cons:

• Wrong part for a 3-inch flush valve tank
• Cannot change bowl height, shape or rough-in
• No published flush volume of its own
• Only one seller lists it

2. American Standard 4000101.020 Cadet 3 Flowise 12-inch — Runner-up

A 1.28 gpf tank with a 3 in flush valve, which is the widest stated opening in this comparison.

Best for: replacing a cracked Cadet 3 FloWise tank Skip it if: you do not already own the matching bowl

This is a tank, not a toilet, and the listing is blunt about it: pair with the Cadet 3 FloWise bowl, sold separately. That single line is the whole buying decision. Get it right and you have replaced half a fixture cheaply. Get it wrong and you own a 32 lb ceramic box that fits nothing you have.

What earns it second place is the hardware. American Standard lists a large 3-in flush valve included, plus a chrome-finished trip lever and coupling components, at 1.28 gpf with WaterSense certification. The dimensions run 17.44 in wide by 15.56 in tall by 10 in deep, and the rough-in is 12 inches. Warranty coverage is described as limited lifetime on ceramics.

Compared with the Gerber and DeerValley fixtures, this asks more homework and delivers a narrower result. There is no seat, no bowl, no glaze claim to weigh. Two sellers list it, which is one more than any other pick here. Against the Fluidmaster kit, it wins on flush valve diameter and loses badly on universality: the kit fits most 2-inch toilets, while this fits one bowl family. That's the trade.

Pros:

• 3 in flush valve, widest stated opening here
• 1.28 gpf with WaterSense certification
• Chrome trip lever and coupling parts included
• Limited lifetime warranty on ceramics
• Two sellers stock it, more than any other pick

Cons:

• Useless without the matching Cadet 3 FloWise bowl
• No bowl, seat or lid in the box
• 32 lb of ceramic to receive and lift
• Fixed 12-inch rough-in only

3. Gerber Maxwell Select Elongated Two-Piece Dual-Flush — Most versatile

The only pick with two stated flush volumes on a canister valve, which makes it the flexible choice for a bathroom with mixed traffic.

Best for: a busy family bathroom needing two flush volumes Skip it if: you cannot handle 81.9 lb in two pieces

Gerber describes a split-flush mechanism at 1.28 and 1.0 gpf, driven by a canister flush valve, with a smooth glazed trapway to keep waste moving. Canister valves open around their full circumference rather than lifting a flap on one hinge, and Gerber's stated aim is a strong bowl-clearing flush for high-traffic bathrooms. Those are the manufacturer's words, not a measured figure, so treat them as design intent.

The practical numbers are better guidance. It ships at 81.9 lb across dimensions of 31 x 28.5 x 17.5 in, with an elongated bowl and a soft close seat included. Two-piece construction means you carry the tank and bowl separately, which is genuinely easier than wrestling a one-piece up a stairwell. It is also the second-most expensive pick here.

Where it loses ground is transparency. The listing gives no bowl height, no rough-in figure and no warranty term, all three of which the DeerValley or American Standard entries state or imply. For a fixture at this price position, that is a real gap, and it means measuring your own floor bolts before ordering. Against the DeerValley one-piece, Gerber is lighter by 12.9 lb and easier to install alone.

Pros:

• Two stated flush volumes, 1.28 and 1.0 gpf
• Canister flush valve rather than a flapper
• Soft close elongated seat included
• 81.9 lb split across two pieces
• Glazed trapway claim for clog resistance

Cons:

• No published bowl height or rough-in figure
• No stated warranty term
• Second-highest price position in this set
• Two-piece joint is one more potential leak point

4. DeerValley Elongated One-Piece Toilet with Comfort Chair — Best minimal setup

A rimless one-piece bowl at ADA seat height, with the fewest seams to scrub of any fixture here.

Best for: a small bathroom wanting one-piece, ADA-height seating Skip it if: your rough-in is not 12 inches

One-piece toilets win on cleaning. There is no gap between tank and bowl where dust and drips collect, and DeerValley pairs that with a rimless bowl, meaning the rinse channel is open rather than tucked under a lip. The listing states dual flush at 1 or 1.28 GPF, a 12 inch rough-in, and an ADA-compliant seat height of 17 1/2 inches. The overall size is given as 18.2 in high with dual flush, on shipping dimensions of 26.6 x 26.8 x 14.5 in.

Depth matters in a small room, and 26.6 in front to back is compact for an elongated bowl. The seat is soft-close and quick-release, which means it lifts off for cleaning without tools. Colour is listed as white with a silver button, so the flush control sits on top of the tank rather than on a lever.

The catch is weight and rigidity. At 94.8 lb this arrives as one solid ceramic mass, so plan a second pair of hands and a clear path. A one-piece also cannot be repaired half at a time: crack the tank and the bowl goes with it, which is the exact scenario the American Standard tank pick solves for two-piece owners. It is the most expensive pick here, and no warranty term is published.

Pros:

• One-piece body, no tank-to-bowl seam
• Rimless bowl for open rinse coverage
• 17 1/2 in ADA-compliant seat height
• 26.6 in depth suits tight bathrooms
• Soft-close, quick-release seat included

Cons:

• 94.8 lb single piece, hard to move alone
• Damage to one half scraps the whole fixture
• Highest price position in this set
• No published warranty term
• Locked to a 12 inch rough-in

5. SEAFLO Porcelain RV Toilet with Elongated Bowl — Best premium

Porcelain and a foot pedal in a 36.8 lb body, built for a vehicle rather than a house.

Best for: an RV or camper needing a porcelain bowl Skip it if: this is your main house bathroom

Most camper toilets are plastic. SEAFLO's pitch is non-porous porcelain that resists staining and odour retention, which is a meaningful difference if you have ever tried to clean a scratched plastic bowl. The listing states 19 inches of standing height, dimensions of 20.51 x 14.17 x 19 in, a soft close seat, and a 4 year warranty. Shipping weight is 36.8 lb.

Flushing is gravity-fed with a foot pedal, and SEAFLO describes a tri-directional rinse plus adjustable water flow through the pedal. That pedal is the interesting part: you control how much water goes in, which matters when your holding tank is finite. Nothing about a fixed gpf rating applies here, so comparing it to the 1.28 gpf house fixtures is comparing two different problems.

Read the placement honestly. This is a camper toilet, and it needs an RV water supply and a black tank behind it. Dropping it into a bathroom with a standard closet flange is not what it's built for. Within this set it sells faster than every pick except the Fluidmaster kit, which tells you the RV crowd is buying. It also carries the highest price position of the seven, and only one seller lists it.

Pros:

• Porcelain bowl instead of plastic
• 4 year warranty stated
• 19 in residential standing height
• Foot pedal gives adjustable water flow
• 36.8 lb, light for a ceramic fixture
• Sells faster here than any pick but the repair kit

Cons:

• Needs RV plumbing, not a household flange
• Highest price position in this set
• No gallons-per-flush figure published
• Only one seller lists it

6. PeacefulHues Compact 15.4 Inch Elongated Two Piece Toilet — Best for pros

A side-mounted flush handle, which is the fix for a tank installed under a shelf or cabinet.

Best for: tight powder rooms with shelving above the tank Skip it if: you are installing it without a second person

Handle position sounds trivial until you install a toilet under a wall cabinet and cannot get your hand to the lever. PeacefulHues moves the handle to the side of the tank specifically for that layout. The listing pairs it with a 1.28 gpf siphonic flush, a cUPC certification, a 12 inch rough-in, and a soft close seat, on a bowl described as 15.4 inch elongated.

The listing text is contradictory on bowl shape, calling it both round front and elongated in different places, so measure from the wall to the front of your existing bowl before committing. Overall dimensions run 28.7 x 27.8 x 17.5 in. The easy-clean glaze claim is a non-porous glossy surface that resists residue, which is standard language across ceramic fixtures rather than a distinguishing figure.

Weight is the headline problem. At 103.6 lb this is the heaviest pick in the set by 8.8 lb over the DeerValley, and that is before you add packaging. It splits into two pieces, which helps, but the bowl alone will be awkward. It sits roughly mid-range for price here, the only pick in that middle tier, and the slowest seller of the seven. Against the Gerber, it gives up the second flush volume and gains the side handle.

Pros:

• Side flush handle for cabinet-crowded tanks
• 1.28 gpf siphonic flush
• cUPC certified with 12 in rough-in
• Soft close seat included
• Only mid-tier price position in this set

Cons:

• 103.6 lb, heaviest pick here
• Listing describes the bowl as both round and elongated
• Single flush volume only
• No stated warranty term
• Slowest seller of the seven

7. KERDE Touchless Toilet Flusher Kit — Best upgrade

A sensor that flushes a chain-lever toilet without anyone touching the handle, added to a fixture you already own.

Best for: shared or guest bathrooms where nobody wants the handle Skip it if: your toilet uses a push button instead of a lever

This is the second-cheapest pick here and the only one that changes behaviour rather than hardware. KERDE states compatibility with chain pull lever toilets, an infrared sensor with a range over 12 inches, a rated life beyond 20,000 flushes, and power from 4 AA batteries that are not included. The unit measures 1.7 x 1.7 x 3.5 in.

Two details make it more useful than it first looks. The sensor mounts outside the tank and can sit wherever it suits the room, rather than being fixed to one spot on the lid. And there's a manual button on the sensor itself, so it doubles as a remote if you would rather flush deliberately than trust motion detection. KERDE describes DIY installation in minutes with basic tools.

The limits are real. If your tank has a top-mounted dual-flush button, as the DeerValley does, there is no chain to pull and this will not work. Battery-powered means batteries eventually die mid-week, and none come in the box. There is no published warranty term. Placed against the Fluidmaster kit, this adds convenience but does nothing for flush strength: a weak flush stays weak, just hands-free.

Pros:

• Second-cheapest pick here
• Sensor mounts anywhere outside the tank
• Manual button doubles as a remote
• 12+ inch detection range claimed
• 20,000 flush lifespan claim

Cons:

• Chain-lever toilets only, no button tanks
• 4 AA batteries not included
• No stated warranty term
• Does nothing to improve flush strength

Fixture or fix? Reading the two halves of this list

This set splits cleanly, and knowing which half you're shopping saves a lot of wasted comparison.

The three whole toilets are Gerber, DeerValley and PeacefulHues. All three include a soft close seat. All three state 1.28 gpf at their strongest setting. Their weights run 81.9 lb, 94.8 lb and 103.6 lb, so freight and lifting are part of the purchase either way.

The four parts and retrofits are Fluidmaster, American Standard, SEAFLO and KERDE. Fluidmaster and KERDE both bolt onto a toilet you already have. American Standard replaces one ceramic half. SEAFLO is a complete fixture, but for a vehicle.

The decision tree is short:

• Toilet flushes weakly or runs, bowl is fine? Fluidmaster.
• Tank cracked, bowl intact, and it's a Cadet 3 FloWise? American Standard 4000101.020.
• Handle unreachable or unhygienic? KERDE, provided you have a chain lever.
• Full replacement, need two flush volumes? Gerber.
• Full replacement, tight room, want easy cleaning? DeerValley.
• Full replacement, cabinet above the tank? PeacefulHues.
• Camper or RV? SEAFLO.

Cross that against your rough-in measurement and you have your answer in a minute. Most shoppers miss that half these listings solve a problem the other half cannot touch.

What do the rough-in and height numbers actually mean?

Rough-in is the distance from the finished wall to the centre of the floor bolts. Three picks here state 12 inches: American Standard, DeerValley and PeacefulHues. If yours measures 10 or 14, those three do not fit, and no adapter makes a 12-inch fixture sit right.

Seat height is the second figure worth checking. DeerValley states 17 1/2 inches as ADA-compliant, and SEAFLO states 19 inches of standing height for its RV unit. Neither Gerber nor PeacefulHues publishes a seat height, which is a genuine blank in those listings. Overall body heights are easier to find: PeacefulHues at 17.5 in on its listed dimensions, Gerber at 17.5 in as well.

Measure three things before you order any of these best flushing toilets home depot candidates:

• Wall to bolt centres, for rough-in.
• Wall to the front lip of your current bowl, for clearance.
• Side wall or vanity to bowl centre, because 15 inches is tight and elongated bowls eat depth.

Skip this and you'll discover the problem with 94.8 lb of ceramic already in your hallway. In practice, the measuring takes five minutes and the return takes a week.

What the listings leave out

Some gaps in this data are worth naming, because they change how much confidence any pick deserves.

MaP scores. The DeerValley title cites MAP 1000g, a waste-removal benchmark. No other whole toilet here states one. Without that figure on Gerber or PeacefulHues, their clog-resistance language stays a claim rather than a comparison.

Warranty terms. Only Fluidmaster (5 Year), SEAFLO (4 year) and American Standard (limited lifetime on ceramics) publish coverage. Three of the seven say nothing, including the two most expensive fixtures.

Wax rings, bolts and supply lines. None of these listings mentions installation hardware. Assume you're buying the ring and the flexible supply separately.

Trapway diameter. Gerber and PeacefulHues describe glaze and siphonic action, not a trapway measurement in inches. That measurement is what actually resists clogs.

Retailer. Nothing here confirms availability at any specific store, which is the honest answer to the retailer half of the search. Check the model numbers I've listed against your preferred shop directly.

The verdict

The Fluidmaster 400AKRP10 wins because it answers the question most people are really asking. A toilet that flushes badly is usually a toilet with aged tank hardware, and an 8 oz kit with a 5 year warranty that fits most 2-inch flush valve toilets fixes that for the smallest outlay in this set. It also carries the longest stated warranty term here, and it's the one buyers choose most often across these seven.

Two conditions flip that recommendation. First, if your flush valve opening measures 3 inches, the Fluidmaster kit is the wrong part and the American Standard 4000101.020 tank becomes relevant instead, on the strict condition that you own the matching Cadet 3 FloWise bowl. Its 3 in flush valve at 1.28 gpf is the widest stated opening in this comparison, and that opening is what moves water fast.

Second, if the fixture itself is wrong for the room, no valve helps. Cracked ceramic, a bowl too tall or too short, a layout that never worked. Then the Gerber Maxwell Select is where I'd start among the whole toilets: 1.28 and 1.0 gpf on a canister valve, a soft close elongated seat, and 81.9 lb split across two liftable pieces. Choose DeerValley over it only if one-piece cleaning and a stated 17 1/2 in seat height matter more than the easier install.

FAQ

Are the best flushing toilets home depot options worth more than a repair kit?

The best flushing toilets home depot shoppers consider are worth the jump only when the fixture itself is wrong: cracked ceramic, bad height, wrong footprint. If the bowl is sound and the flush went weak, the Fluidmaster kit costs a fraction of any whole toilet here and targets the fill valve, flapper and handle that usually caused it.

Is a dual-flush toilet worth it over a single 1.28 gpf model?

A dual-flush toilet is worth it if your bathroom sees heavy mixed use. Gerber lists 1.28 and 1.0 gpf, and DeerValley lists 1 and 1.28 GPF, so both give you a lighter option for liquid waste. PeacefulHues offers one volume at 1.28 gpf and gains a side-mounted handle instead. Neither approach is wrong, they just optimise differently.

What flush valve size do I need for the Fluidmaster kit?

The flush valve size you need is 2 inches. Fluidmaster states the 400AKRP10 fits most 2-inch flush valve toilets and suits 1.6 to 3.5 gallons per flush models or larger, with a fill valve adjusting from 9 to 14 inches. Lift your tank lid and measure the flapper opening. A 3-inch opening needs different parts entirely.

Gerber Maxwell Select or DeerValley one-piece: which should I install?

Gerber Maxwell Select or DeerValley comes down to install logistics against cleaning. Gerber ships at 81.9 lb in two pieces, so one person can manage it, and gives you 1.28 and 1.0 gpf. DeerValley is 94.8 lb in one solid piece with a rimless bowl, no tank seam, and a stated 17 1/2 in ADA seat height. Heavier to fit, easier to scrub.

What mistake do first-time toilet buyers make most often?

The mistake first-time toilet buyers make most often is ordering before measuring the rough-in. American Standard, DeerValley and PeacefulHues all specify 12 inches from wall to bolt centres. A 10 or 14 inch rough-in will not accept them. Measure that distance, plus front clearance and side clearance, before a 103.6 lb box arrives at your door.

Start with the tank lid, not the shopping cart. Lift it, look at the flapper opening, and measure it. A 2-inch opening on a bowl you otherwise like means the Fluidmaster 400AKRP10 is very likely the whole job, done in an afternoon with a 5 year warranty behind it. That single check is what separates a small part order from an 80-pound freight delivery and a Saturday on the bathroom floor. If the measurement or the fixture rules the kit out, work down the decision list above: your rough-in figure and your handle position will point at exactly one of the remaining six.
