Best One Piece Toilet for the Money: HOROW Wins

The best one piece toilet for the money in this set is the HOROW T0338W, a 12-inch rough-in unit with a 17.3-inch ADA chair height and a 1.1/1.6 GPF dual flush. It wins because it publishes the fullest spec sheet of the six: seat height, weight, dimensions, trapway size and a one-year warranty are all on the listing. If your bathroom sits on a 10-inch rough-in, HOROW's alternate version is the swap; if you want a rimless bowl at a lower flush volume, the DeerValley DV-1F0437 takes the runner-up slot.

Best one piece toilet for the money at a glance

The misconception about picking on price alone

The phrase "for the money" gets read as "cheapest that flushes". That mindset is how people end up replacing a toilet twice in five years. Price rank matters, but it is the third question, not the first.

The first is whether the unit fits your rough-in and your floor. The second is whether the flush volume matches your local code and your water bill. A one piece toilet that costs less on the listing but forces a plumber to shift a flange has spent your savings before it leaves the box.

Look at what the picks here actually publish:

• HOROW T0338W states a 12-inch rough-in, a 26 x 26.6 x 15-inch footprint, 99.2 lb weight and a 1-year warranty on the listing.
• DeerValley DV-1F52812 states a 12-inch rough-in, 78 lb weight and a 1-year warranty.
• DeerValley DV-1F0437 states 17.5-inch ADA height and 1/1.28 GPF, but the listing does not print a warranty term.
• Casta Diva CD-W001 publishes a 1.0 GPF pressure-assist flush and a 17.2-inch seat, but does not print a weight, rough-in or warranty on the listing.

Buyers who compare only the sticker price treat those four as interchangeable. They are not. The best one piece toilet for the money is the one where the spec sheet closes the door on surprises before delivery day.

How I narrowed six listings by profile

I built the shortlist around the profiles a real bathroom buyer falls into, then read every product listing top to bottom, copying only what the brand actually printed.

1. Small bathroom, standard 12-inch rough-in, ADA seat wanted. This is the biggest bucket in the category. The HOROW T0338W and both Casta Diva units all fit here, but only HOROW publishes the full dimensional card.
2. Small bathroom, round bowl acceptable. The DeerValley DV-1F52812 lands here alone with a 24.6-inch depth and a standard-height round bowl.
3. Renovation with a water-use target. The DeerValley DV-1F0437 and the Casta Diva CD-W001 both flush at 1.0 GPF on the light cycle, but the Casta Diva uses pressure assist.
4. Contractor stocking for a fit-out. The Casta Diva CD-T005 is the skirted, WaterSense-labelled unit at 1.1/1.6 GPF with a 17-inch ADA seat.

The Iconikal roll is included because it appeared in the data. It is a novelty item, not a toilet, and it is called out honestly below rather than dressed up. Anyone hunting for a genuine best one piece toilet for the money should treat it as comic relief and skip its section.

1. HOROW T0338W One Piece Toilet — Best overall

The HOROW T0338W is the best one piece toilet for the money here because it prints more of the numbers a buyer needs than any other pick.

Best for: small bathrooms with a 12-inch rough-in needing ADA seat height Skip it if: your rough-in is 10 inches and you did not pick that version

The T0338W is the only pick in this set that publishes seat height (17.3 inches), weight (99.2 lb), footprint (26 x 26.6 x 15 in), trapway size (a HOROW-claimed 2-inch fully glazed trapway) and a 1-year warranty on the same listing. That combination is why it takes the top slot even though it is the second-most-expensive pick here. Cheaper toilets in this group leave you guessing on at least one of those figures, and any of them can turn install day into a return.

The dual flush is stated as 1.1/1.6 GPF, which matches most US code and lets a full flush clear waste that lighter systems struggle with. HOROW claims a siphon flush and a soft-close PP seat. Attribute those to the brand rather than treating them as measured, but the underlying siphon design at 1.6 GPF is well understood. HOROW also offers a 10-inch rough-in variant, which is the escape hatch for older homes.

The trade-off is size: at 99.2 lb, this is the heaviest of the four true one piece toilets here. Plan for two people on install day.

Pros:

• Complete spec card: seat height, weight, dimensions, trapway, warranty
• 17.3-inch ADA chair height on the listing
• 1.1/1.6 GPF dual flush matches US code
• 10-inch rough-in version available for older homes
• One of only two picks with a printed warranty term

Cons:

• Heaviest of the four functional toilets at 99.2 lb
• Second-highest price position in this set
• Warranty runs only 1 year

2. DeerValley DV-1F52812 Compact One Piece Toilet — Best upgrade

The DeerValley DV-1F52812 is the compact-bathroom answer, with the shallowest depth in the set at 24.6 inches.

Best for: tight powder rooms where a round bowl still fits the profile Skip it if: you want an elongated bowl or ADA-height seating

This unit's headline number is the 24.6-inch depth, which is roughly two inches shorter than every other one piece toilet here. In a half-bath where the door swing already scrapes the bowl, those inches decide whether the room works. DeerValley states a 78 lb weight, a 12-inch rough-in, a 1-year warranty and a 1.1/1.6 GPF dual flush.

DeerValley claims the soft-close seat operates at 28dB and that the dual flush saves about 16,500 gallons a year against an older 3.5 GPF unit. Both are the brand's figures rather than independent measurements, but the water-saving math tracks any 1.6 GPF unit versus a legacy toilet.

Two honest losses. First, the bowl is round rather than elongated, which most adults find less comfortable for longer sits. Second, the seat is standard height, not ADA, so anyone with knees, hips or a household member over about 65 should look at the HOROW instead. This is a genuine trade of comfort for footprint, and if you have the floor space, take it.

Pros:

• 24.6-inch depth, the shallowest in this set
• 78 lb, the lightest true toilet here
• 1.1/1.6 GPF dual flush
• 12-inch rough-in and 1-year warranty published
• Fully skirted profile for easier cleaning

Cons:

• Round bowl rather than elongated
• Standard seat height, not ADA
• 28dB soft-close claim is DeerValley's own

3. DeerValley DV-1F0437 Elongated Rimless One Piece — Best minimal setup

The DV-1F0437 is the water-target pick: 1.0/1.28 GPF dual flush on a rimless elongated bowl.

Best for: renovators who want a rimless bowl and 1.28 GPF ceiling Skip it if: you need a printed warranty term on the listing

Two things separate this DeerValley from the T0338W. First, the flush ceiling is 1.28 GPF rather than 1.6, which matches the WaterSense threshold and is the flush volume required by code in California and a growing list of jurisdictions. Second, DeerValley states a MAP score of 1000g, the highest published score for waste removal in this set.

The seat sits at 17.5 inches for ADA compliance, the footprint runs 26.6 x 26.8 x 14.5 inches, and DeerValley claims a rimless bowl. Rimless designs remove the crevice under the traditional rim where mineral scale collects, so cleaning is simpler in hard-water homes.

The catch is the paperwork. The listing does not print a warranty term, where both HOROW picks state one year. If a warranty matters to you, HOROW is the safer buy. The DV-1F0437 also flushes at a lower volume, which for very old drain lines with shallow slope can occasionally underperform. Modern rough-plumbing handles it, but budget-remodel homes with cast-iron waste stacks should test-flush before signing off.

Pros:

• 1.0/1.28 GPF, the lowest flush ceiling in the set
• 17.5-inch ADA seat height
• Rimless bowl claim, easier cleaning in hard-water homes
• MAP 1000g stated on the listing
• Elongated bowl for adult comfort

Cons:

• No warranty term printed on the listing
• 1.28 GPF can strain very old drain lines
• Rimless claim is DeerValley's own

4. Casta Diva CD-W001 Pressure-Assist One Piece — Best premium

The Casta Diva CD-W001 is the pick for low-pressure homes: a 1.0 GPF pressure-assist flush that does not need electricity.

Best for: low-pressure homes where a 1.0 GPF pressure-assist flush earns its keep Skip it if: you want a published weight, warranty or rough-in figure before buying

Casta Diva claims an air-pressure assisted flush at 1.0 GPF, a foot-kick or side-button hands-free control, and a MAP score of 1000g on a siphon jet flush. Pressure assist matters in one specific situation: a home where the incoming water pressure sags and a gravity 1.28 GPF toilet leaves streaks. The trapped-air tank compresses on refill and slams the flush volume through when triggered. It is louder than a gravity flush. That is the design.

Seat height is stated at 17.2 inches ADA, and the footprint measures 19.3 x 26.9 x 15 inches, though the 19.3 figure looks unusually shallow for an elongated bowl and probably reflects the shipping crate rather than the toilet.

The reason this is not the outright winner is the spec card. The listing does not print weight, does not confirm rough-in in inches on the visible spec table, and does not state a warranty. It is the most expensive pick here and the least documented. If pressure assist is your must-have, buy it. If not, the HOROW gives you more paperwork for less money.

Pros:

• 1.0 GPF pressure-assist flush, the lowest volume with pressure help
• MAP 1000g claimed on the listing
• 17.2-inch ADA seat height
• Foot-kick hands-free flush option
• Non-electric operation

Cons:

• Most expensive pick in this set
• No published weight, warranty or rough-in figure
• Pressure-assist mechanisms are louder than gravity flush

5. Casta Diva CD-T005 Skirted One Piece — Best for pros

The CD-T005 is the pro-spec skirted unit: WaterSense-eligible 1.1/1.6 GPF dual flush on a 17-inch ADA seat.

Best for: contractors buying for a skirted, WaterSense-labelled fit-out Skip it if: you need warranty and weight numbers on the listing

Casta Diva positions this one as the workhorse: a skirted one piece with a 17-inch ADA seat, 1.1/1.6 GPF dual flush, a stated MAP rating of 1000, and a fully glazed trapway. The brand claims EPA WaterSense criteria are met at the 1.1 GPF light-flush setting. Footprint is 25.4 x 27.2 x 14.4 inches, which sits between the two DeerValley picks.

Contractors will read the value here differently to homeowners. The skirted body means fewer crevices during a punch-list clean; the gravity flush means fewer moving parts to warranty in year two; the mid price position keeps a per-unit budget realistic across a fit-out.

The gaps are the same as the CD-W001's: no printed weight, no warranty term on the listing, no explicit rough-in inches. If you are installing this yourself for the first time, the HOROW is the friendlier buy. If you have installed 30 toilets this year and know a 12-inch rough-in gravity elongated when you see one, this one is fine and sits at a mid price position for the set.

Pros:

• WaterSense-eligible dual flush at 1.1/1.6 GPF claim
• 17-inch ADA seat height
• Skirted body simplifies cleaning
• MAP 1000 stated by Casta Diva
• Mid price position for a skirted elongated unit

Cons:

• No warranty term printed on the listing
• No published weight or rough-in figure
• Pro-friendly rather than beginner-friendly

6. Iconikal 240-Sheet Money Toilet Paper — Best budget pick

The Iconikal roll is a novelty gag gift, not a toilet, and I am saying so plainly.

Best for: a gag gift for the friend who just remodelled their bathroom Skip it if: you clicked here for an actual toilet

This item appeared in the product feed because the search phrase contains the word "money", and Amazon's algorithm dropped a joke roll into the results. It is 240 sheets of 2-ply paper printed to look like 100-dollar bills. Iconikal says it is plumbing-safe. It is a single roll.

I have kept it in the ranking rather than hiding it because pretending it is not there would be worse than the honest disclosure. The best one piece toilet for the money is one of the four true toilets above, and if you are shopping seriously you should treat this line as noise. If you are shopping for a housewarming joke, the Iconikal roll is exactly the kind of thing that gets a laugh at a bathroom-reveal party. It is the cheapest pick in the set by a comfortable margin, and it is the only item here with more than one seller listed.

Pros:

• Actually functions as toilet paper
• Cheapest listing in this set
• Multiple sellers listed
• 2-ply construction

Cons:

• Not a toilet
• Single roll only
• No use to anyone buying a fixture

What decides value in a one piece toilet?

Value in this category is not a price line, it is the ratio of published spec to unpublished risk. A listing that prints a rough-in figure, a weight, a warranty term and a flush volume gives you fewer places to be surprised on install day. A listing that publishes only a photo and a flush claim is asking you to buy on trust.

Rank the questions in this order:

1. Rough-in in inches. 12-inch is standard; 10-inch is older housing; 14-inch is rare. Miss this and the toilet does not sit on the flange.
2. Seat height in inches. ADA "chair" or "comfort" height runs 17 to 19 inches from floor to seat. Standard runs 14 to 16 inches. Anyone over 60 or with knee issues wants ADA.
3. Flush volume in GPF. 1.28 GPF is WaterSense; 1.6 GPF is the older US code ceiling; anything under 1.28 GPF usually needs pressure assist or a proven siphon design.
4. Footprint in inches. Measure your existing toilet's depth before ordering. A shallow bathroom cannot accept a 27-inch-deep bowl.
5. Warranty term. One year is the floor. Anything unstated is a question mark.

The HOROW T0338W answers all five on its listing. That is the entire case.

How do dual flush and pressure-assist compare?

Dual flush and pressure-assist solve two different problems. Dual flush is a two-button gravity system offering a light flush for liquids and a full flush for solids. In this set, HOROW and both DeerValley picks and the Casta Diva CD-T005 are dual flush at either 1.0/1.28 or 1.1/1.6 GPF. Pressure assist uses a sealed inner tank that compresses air on refill and pushes the flush volume out with mains water pressure behind it. The Casta Diva CD-W001 is the only pressure-assist pick here.

Choose dual flush if:

• Your household water pressure is normal (roughly 40 to 80 psi at the fixture).
• You want a quieter flush.
• Repair parts should be easy to find at any hardware store.

Choose pressure assist if:

• Your incoming pressure is low or inconsistent.
• You have had streaking or double-flush issues with a 1.28 GPF gravity toilet.
• You accept a louder flush in exchange for a stronger one at 1.0 GPF.

The best one piece toilet for the money in most homes is a gravity dual flush at 1.1/1.6 GPF, which is why the HOROW leads. Pressure assist is a genuine tool for a specific job, not a general upgrade.

What the listings do not tell you about rough-in

Rough-in is the distance from the finished wall behind the toilet to the centre of the closet flange in the floor. Most US homes built after 1980 use a 12-inch rough-in. Homes built between 1930 and 1970 often use 10-inch or 14-inch. The listing tells you what the toilet supports. The listing does not tell you what your bathroom has.

Before ordering any pick here:

• Measure from the finished drywall to the centre of the flange bolts, not to the base of the existing toilet.
• If the number is 12 inches plus or minus half an inch, any of the four true toilets here fits.
• If the number is 10 inches, ask HOROW for the 10-inch variant; the T0338W listing mentions it.
• If the number is anything else, do not buy from a stock listing without confirming with the brand.

Two related gotchas. First, the supply line stub sits five to seven inches to the left of the flange centre on most US homes, and a fully skirted one piece toilet can hide it: check the toilet's side access opening before install. Second, the flange itself sits on the finished floor. New tile raises the flange relative to the toilet base, and you may need an extender ring. Buy one at the same time as the toilet; it is cheap and prevents a second trip.

The verdict

The best one piece toilet for the money in this set is the HOROW T0338W. It wins because it publishes seat height (17.3 inches), weight (99.2 lb), footprint (26 x 26.6 x 15 in), a 12-inch rough-in with a 10-inch alternate, a 1.1/1.6 GPF dual flush, and a 1-year warranty on the same listing. No other pick prints all of that.

Two conditions flip the choice. First, if your bathroom is genuinely tight and a round bowl is acceptable, the DeerValley DV-1F52812 is the pick: at 24.6 inches deep and 78 lb, it fits and lifts where the HOROW does not. Second, if you have low household water pressure or a WaterSense mandate and want the lowest flush volume with reliable performance, the DeerValley DV-1F0437 at 1.0/1.28 GPF with a claimed MAP of 1000g takes the slot.

The Casta Diva CD-W001 is the right answer only for buyers who specifically need pressure-assist. The CD-T005 is the pro-stock pick when a printed warranty is not a dealbreaker. The Iconikal roll is a joke listing. Choose the HOROW and get on with your day.

FAQ

Is a one piece toilet worth the extra cost over a two piece?

One piece toilets are worth the extra cost when cleaning and appearance rank high for you. The seamless body has no gap between tank and bowl, so mineral scale and grime cannot collect where a two piece would need a scrub. In this set, all four true toilets are skirted or near-skirted, which pushes the same benefit further down the base. The trade-off is weight: at 99.2 lb the HOROW needs two people to install.

What decides the best one piece toilet for the money?

The best one piece toilet for the money is decided by how many of the five install-day questions the listing answers before you buy. Rough-in, seat height, flush volume, footprint and warranty. The HOROW T0338W prints all five. Cheaper listings that skip warranty or weight cost less at checkout and more in the risk you carry. Value is documented spec, not sticker price.

HOROW T0338W or DeerValley DV-1F0437: which one should I choose?

Choose the HOROW T0338W if you want the fullest spec card and a printed 1-year warranty on the listing. Choose the DeerValley DV-1F0437 if a 1.28 GPF WaterSense flush ceiling matters to you or your local code requires it, and you accept that the listing does not state a warranty term. Both are ADA-height at 17.3 and 17.5 inches respectively.

Will a 12-inch rough-in toilet fit my bathroom?

A 12-inch rough-in toilet fits most US bathrooms built after 1980. Measure from the finished wall behind the toilet to the centre of the closet flange bolts. If the number is between 11.5 and 12.5 inches, any 12-inch unit here fits. Older homes may have a 10-inch or 14-inch rough-in; HOROW offers a 10-inch version of the T0338W for that case.

Are the flush claims on these listings independent or from the brand?

The flush claims on these listings are the brands' own. HOROW's siphon flush description, DeerValley's 28dB soft-close and MAP 1000g figures, and Casta Diva's pressure-assist and MAP claims are all manufacturer-published. MAP scores of 1000g are the highest tier in the standard test, and dual flush at 1.1/1.6 GPF is well-understood industry design, but treat any number without an independent lab reference as an attributed claim.

For a small-to-mid US bathroom with a 12-inch rough-in and no unusual water pressure, order the HOROW T0338W, measure your rough-in before it arrives, and buy a flange extender ring with the same shipment if your finished floor sits proud of the flange. That two-item order handles almost every install this category throws at you. The HOROW leads not because it is the cheapest, and not because it is the most spec-heavy on paper, but because it is the pick where the listing and the install-day reality line up closely enough that surprises are unlikely. Every other pick here trades a piece of that certainty for a specific advantage. If the advantage matches your bathroom, take the swap.
