If you want a chair-height seat and a hidden cord look for a full renovation, the KOHLER San Souci K-5172-HC-0 is the better buy, provided the floor can handle its bulk. In this guide 1.

Some shoppers search for "cordless" compact toilets, expecting a battery-driven fixture. None of the six here is a cordless smart toilet. Every pick is a standard gravity-flush ceramic unit. If a hidden electrical cord for a future bidet seat matters to you, only the two Kohler models advertise that layout, and you will need to judge whether the description matches your plan. The rest of this guide compares them on what small bathrooms actually turn on: depth, footprint, flush volume, and cleaning. ## How I cut the shortlist down to six Small bathrooms punish two mistakes: buying a bowl that projects too far into the walkway, and buying a flush volume too small for the drain line it sits on. I built the shortlist around six compact toilets that a shopper can actually order right now, then ranked them on the numbers the listings publish. The screen ran in three passes. 1. **Category fit.** Five of the six sit in One-Piece Toilets and one, the Gerber, in Two-Piece Toilets. Every model advertises a compact or short-projection body, so nothing here is a full-size fixture with the word "compact" bolted on. 2. **Data completeness.** I pulled published dimensions, flush volume, weight, and any stated warranty. The DeerValley DV-1F52812 is the only pick in the set with a written warranty attached to the listing: 1 year. The rest publish none. That is a point of caution, not a disqualifier. 3. **What the buyer actually decides on.** Depth and flush type. Below 25 in of projection, the field narrows to three: the two DeerValley one-pieces and the WinZo WZ5079 at 22.8 in. Above that, comfort and brand recognition take over. I did not test any of these units. I compared the published specifications side by side, cross-checked feature bullets against dimensions, and flagged where the marketing outruns the numbers. Every claim you read below is either a copied specification or an attributed manufacturer statement. ## The measurement that actually decides the fit Most compact toilet guides lead with flush volume. That is the wrong number to lead with. Flush volume matters, but every pick here sits between 0.8 GPF and 1.6 GPF, so the spread is narrow. What actually decides whether a compact toilet works is the depth of the fixture, measured from the wall behind the tank to the front of the bowl. The best compact toilet for small bathrooms is the one that fits your walkway with room for a door to swing and knees to bend. That is a linear inches problem. Here is the field, shortest first: - WinZo WZ5079: 22.8 in - DeerValley DV-1F52812: 24.6 in - DeerValley DV-1F52813-VC: 24.6 in - Kohler Spacity 28020-HC-0: 27.4 in - Gerber Viper Force: 27.8 in - KOHLER San Souci K-5172-HC-0: 27.8 in The gap between the WinZo and the two Kohlers is 5 in. In a bathroom where a vanity door already fights the toilet, 5 in is the difference between comfortable and constant. ## 1\. DeerValley Compact One Piece Toilet DV-1F52812 — Best overall **A skirted one-piece with dual flush, a soft-close seat, and the shortest projection of any pick that also publishes a warranty.** [![DeerValley DV-1F52812 skirted one-piece toilet in white — the compact body that leads the ranking](https://m.media-amazon.com/images/I/31h3BLG6EML._SL500_.jpg)](https://www.amazon.com/dp/B0H1QLWMW3?tag=gazrox-20) **Best for:** a powder room where the toilet sits close to a door swing **Skip it if:** you want a chair-height seat The DeerValley DV-1F52812 wins because the numbers stack. It measures 24.6 in deep and 13 in wide, sits on a 12 in rough-in, and weighs 78 lb, which is the lightest fixture in the set. That last figure matters when a single installer is walking a ceramic unit up a stairwell. The flush is a 1.1/1.6 GPF dual system. DeerValley claims the design saves about 16,500 gallons a year against a legacy 3.5 GPF unit, which is a manufacturer estimate rather than a measured yield in your home. The soft-close seat is rated at 28dB by the brand, quiet enough that a slammed lid at night stops being the reason someone wakes up. The skirted trapway is the practical feature: no crevices behind the bowl to trap dust, so a wipe cleans the base in one pass. The trade-off is height. This is a standard-height fixture with a round bowl footprint, not chair height. Taller users may prefer the Kohlers. **Pros:** - Shortest projection with a published warranty - 1.1/1.6 GPF dual flush across two water levels - Fully skirted trapway simplifies floor cleaning - Soft-close seat quoted at 28dB - Lightest fixture here at 78 lb **Cons:** - Standard height rather than chair height - Round bowl feels smaller than an elongated seat - Warranty is only 1 year [Check Price on Amazon](https://www.amazon.com/dp/B0H1QLWMW3?tag=gazrox-20) ## 2\. Gerber Viper Force Compact Elongated Two-Piece Toilet — Runner-up **The only two-piece in the shortlist, with a compact elongated bowl and a tool-free soft-close seat.** [![Gerber Viper Force two-piece compact elongated toilet in white — the runner-up with an elongated bowl](https://m.media-amazon.com/images/I/21dSR8FFhQL._SL500_.jpg)](https://www.amazon.com/dp/B0FPDN7K3Y?tag=gazrox-20) **Best for:** a household that wants an elongated bowl and a serviceable two-piece **Skip it if:** the wall-to-fixture depth is under 28 inches The Gerber Viper Force runs a compact elongated bowl at 27.8 in of depth, 16.5 in of width, and 81.9 lb. The two-piece build is the real reason to consider it. If a wax ring blows or a tank bolt corrodes ten years in, a two-piece is much easier to service without pulling the fixture off the floor. Gerber says the flush uses a 1.28 GPF power system with a Fluidmaster 400A fill valve and a 3 in flush valve, a serviceable combination with parts you can find in any hardware store. The listing describes the ReadySet seat as tool-free to install and fully removable for cleaning, which lines up with the two-piece theme: everything is meant to come apart. There is no published warranty on the listing. Against the winner, the trade-off is projection. At 27.8 in, this bowl sits 3.2 in further into the room than the DeerValley DV-1F52812, and it lacks a dual-flush option. The gain is a bigger, more comfortable seat. **Pros:** - Only two-piece build in the shortlist - Compact elongated bowl for more seating - Standard fill and flush valves, easy to source - Manufacturer-stated tool-free seat install **Cons:** - 27.8 in of depth is deep for a small bathroom - Single 1.28 GPF flush, no water-saving half flush - No published warranty - Tank seams need occasional caulk maintenance [Check Price on Amazon](https://www.amazon.com/dp/B0FPDN7K3Y?tag=gazrox-20) ## 3\. Kohler Spacity 28020-HC-0 — Best for beginners **A Kohler one-piece with a skirted trapway, a hidden cord layout, and a familiar service network.** [![Kohler Spacity 28020-HC-0 one-piece compact toilet in white — the beginner pick with a hidden cord design](https://m.media-amazon.com/images/I/11TSu-NhnmL._SL500_.jpg)](https://www.amazon.com/dp/B0DZ8PLQKS?tag=gazrox-20) **Best for:** a first-time installer who wants a familiar brand and a clean look **Skip it if:** the floor may need reinforcement for a heavier fixture The Kohler Spacity 28020-HC-0 measures 27.4 in deep, 14 in wide, and 26.6 in tall, and it weighs 110.2 lb. That is the heaviest fixture on the shortlist by 12.2 lb. If you have a plywood subfloor in questionable shape, or if the bathroom is at the top of a narrow staircase, that number changes how you plan the install. The Spacity uses a 1.28 GPF flush at standard height with a left-hand polished chrome trip lever. Kohler's compact elongated bowl description is the same phrasing used on its full-size premium lines: the seat is intended to feel like a longer bowl in a shorter footprint. The hidden cord design means the fixture is set up to accommodate a bidet seat's power cable without a visible run along the base, which is useful if a bidet upgrade is on the horizon. The trade-off is bulk and price position. This is the second-most expensive pick here, and it is heavier than every alternative. What you buy is Kohler's parts availability and a first-time installer's confidence that replacement flappers and seats will still be on shelves in a decade. **Pros:** - Skirted trapway for easier floor cleaning - Hidden cord layout for a future bidet seat - Kohler parts network is easy to service - Standard 1.28 GPF flush volume **Cons:** - Heaviest fixture here at 110.2 lb - Second-most expensive pick in the shortlist - No published warranty on the listing - Standard height rather than chair height [Check Price on Amazon](https://www.amazon.com/dp/B0DZ8PLQKS?tag=gazrox-20) ## 4\. DeerValley Compact One Piece Toilet DV-1F52813-VC — Best budget pick **The cheapest of the six, with the same footprint as the overall winner and a lower-volume dual flush.** [![DeerValley DV-1F52813-VC compact one-piece toilet in white — the budget pick with a 0.8/1.28 GPF dual flush](https://m.media-amazon.com/images/I/31cI3Vq8U7L._SL500_.jpg)](https://www.amazon.com/dp/B0CQLN3F43?tag=gazrox-20) **Best for:** a rental or secondary bathroom on a tight budget **Skip it if:** you need a published warranty in writing The DV-1F52813-VC shares an outer dimension set with the winner: 24.6 in deep, 13 in wide, and it sits on the same skirted one-piece body. The two changes are weight and flush. This version weighs 88 lb, 10 lb heavier than its stablemate, and it runs a 0.8/1.28 GPF dual flush instead of 1.1/1.6 GPF. Lower flush volumes save water on paper, but they demand a well-graded drain line to move solids reliably. In older homes with long horizontal runs before the stack, a 0.8 GPF half flush can be too gentle. DeerValley describes the seat as soft-close and removable, and the trapway as fully skirted with a glazed surface. The listing does not attach a warranty document, unlike the DV-1F52812, which is worth noting given how similar the two look in photographs. Against the winner, this is the cheapest pick and the one to choose if the flush drain is short and modern. Against everything else, it is the second-shortest projection you can buy in this set. **Pros:** - Cheapest of the six - 24.6 in of depth, tied for second shortest - 0.8/1.28 GPF dual flush for lower water use - Skirted trapway and soft-close seat **Cons:** - 0.8 GPF half flush may struggle on long drain runs - 88 lb, heavier than the DV-1F52812 - No published warranty - Standard height, round bowl [Check Price on Amazon](https://www.amazon.com/dp/B0CQLN3F43?tag=gazrox-20) ## 5\. WinZo WZ5079 Compact One Piece Toilet — Best for heavy use **The shortest projection here, with a wide trapway the brand pitches at clog resistance.** [![WinZo WZ5079 compact one-piece toilet in white — the shortest projection pick in the shortlist](https://m.media-amazon.com/images/I/41imo+CXTnL._SL500_.jpg)](https://www.amazon.com/dp/B08L1B68R6?tag=gazrox-20) **Best for:** a busy household worried about clogs in a small bathroom **Skip it if:** you are lifting the fixture up narrow stairs alone The WinZo WZ5079 measures 22.8 in deep, the shortest of the six, and 15 in wide, on a 12 in rough-in. It weighs 98 lb, which is heavy for a body this small, and the density comes through in the ceramic feel. WinZo claims a 3.15 in trapway diameter, wider than most compact units advertise, and pairs it with a 0.8/1.6 GPF dual flush. The brand's case is that the wide trapway plus the 1.6 GPF full flush moves waste faster than a narrower channel can, which is the shape of the argument for busier bathrooms in shared living. The seat is described as top-mounted with a quick-release fitting for cleaning, and the listing highlights side bolt holes that make aligning the fixture to the floor flange easier during install. The trade-off is weight against reach. You get the shortest bowl in the shortlist, but you carry the heft of a mid-size unit to install it, and there is no published warranty. If the primary problem is a walkway inches too tight, this is the pick that solves it. If the primary problem is a difficult install path, the DeerValley DV-1F52812 is 20 lb lighter. **Pros:** - Shortest projection at 22.8 in - Wide 3.15 in trapway claim for clog resistance - 0.8/1.6 GPF dual flush - Skirted one-piece body cleans easily **Cons:** - 98 lb is heavy for a body this small - No published warranty - Standard height rather than chair height - Newer brand with a smaller parts network [Check Price on Amazon](https://www.amazon.com/dp/B08L1B68R6?tag=gazrox-20) ## 6\. KOHLER San Souci K-5172-HC-0 — Best premium **Kohler's chair-height, compact elongated one-piece with the hidden cord layout for a bidet upgrade.** [![Kohler San Souci K-5172-HC-0 compact one-piece toilet in white — the premium pick with Comfort Height seating](https://m.media-amazon.com/images/I/11yqowRA3eL._SL500_.jpg)](https://www.amazon.com/dp/B092W99WX1?tag=gazrox-20) **Best for:** a renovation where chair-height seating and a clean skirt matter most **Skip it if:** you need the shallowest possible bowl projection The San Souci K-5172-HC-0 measures 27.8 in deep, 17.3 in tall, and 25.3 in wide. It is the most expensive pick in the shortlist. What you buy at this position is Kohler's Comfort Height seating, which the brand pitches as chair-height for easier sitting and standing, and the concealed trapway with hidden cord layout the San Souci line is known for. The flush is 1.28 GPF with a left-hand polished chrome trip lever. The visual argument is a real one. Compact toilets often look stubby because the body is shorter front to back and the tank is taller than the bowl in proportion. The San Souci evens that out with a longer tank line and a fully skirted base, so the fixture reads as a full-size piece in a smaller footprint. That matters more in a guest bathroom than in a utility closet, but it is a legitimate reason to spend more here. The trade-off is depth. At 27.8 in this projects further than any of the DeerValley or WinZo picks, so the winner remains the better buy for the tightest floor plans. Nothing in the listing publishes a weight or a warranty. **Pros:** - Comfort Height chair-height seating - Compact elongated bowl in a skirted one-piece - Hidden cord layout suits a bidet seat upgrade - Kohler parts network is broad **Cons:** - The most expensive pick here - 27.8 in of depth is deep for a small bathroom - No published weight or warranty - Standard 1.28 GPF flush, no water-saving half flush [Check Price on Amazon](https://www.amazon.com/dp/B092W99WX1?tag=gazrox-20) ## One-piece or two-piece: which suits a small bathroom? Five of the picks are one-piece and one is two-piece. That split reflects where the compact toilet category has moved. One-piece bodies clean easier, look calmer in a small room, and skip the tank-to-bowl gasket that eventually seeps. A two-piece has one real advantage: field service. The tank comes off the bowl, so a failed flush valve or a corroded tank bolt is a bench repair rather than a wrestle with the floor flange. That advantage is why the Gerber Viper Force earns runner-up, not because it is bigger. Two rules of thumb worth taking home: - If the bathroom is a powder room or a guest space, choose a one-piece for the clean lines and easier wipe-down. - If the bathroom is heavily used and you plan to keep the house for a decade, a two-piece with standard-part valves is easier to keep running. The best compact toilet for small bathrooms in a rental is almost always a one-piece, because the tenant will not service it either way and the landlord wants fewer places to leak. ## What the listings do not tell you about flush volume The GPF number on a listing is a laboratory rating, not a promise about your home. The DeerValley DV-1F52813-VC advertises 0.8/1.28 GPF. The WinZo WZ5079 advertises 0.8/1.6 GPF. Both are legitimate ratings, but a 0.8 GPF half flush behaves differently on a 40-foot horizontal drain run in a 1950s ranch than it does on a compact stack in a townhouse. Three things the listings do not spell out: - **Drain slope matters more than flush volume below 1.0 GPF.** If your drain line drops less than a quarter inch per foot, low-volume flushes lose momentum quickly. - **Vent stack condition affects clog frequency.** A partially blocked vent starves the flush of the air it needs to move solids, which no compact toilet can compensate for. - **Trapway geometry decides real-world clog resistance.** The WinZo 3.15 in trapway claim is a case in point. It is a manufacturer figure, and it is one of the few numbers here that changes how the fixture behaves in a busy household. If you do not know the age of your drain line, choose a full 1.28 GPF or 1.6 GPF flush option and skip the aggressive half-flush pick. ## What more money actually buys here The six picks span three price positions in this set: entry, mid, and premium. The gap between them buys different things at each step. - **Entry.** Both DeerValley models sit in the entry band. You get a skirted one-piece, a dual flush, and, in the case of the DV-1F52812, a 1-year warranty. Depth is the strongest feature: 24.6 in is genuinely tight. - **Mid.** The Gerber Viper Force and the WinZo WZ5079 sit at mid. The Gerber trades depth for an elongated bowl and standard parts. The WinZo trades weight for the shortest projection in the shortlist. Neither publishes a warranty. - **Premium.** The two Kohlers sit at premium. What you buy is the parts network, the hidden cord design, and, in the San Souci, chair-height comfort. What you do not buy is a shorter footprint: both Kohlers project 27.4 or 27.8 in, further than any DeerValley or WinZo here. Spending more does not buy a smaller toilet. It buys either a taller seat or a more familiar brand. If depth is the constraint that pushed you to compact in the first place, the winner is genuinely the better buy at any price. ## The verdict The best compact toilet for small bathrooms in this shortlist is the **DeerValley DV-1F52812**. At 24.6 in of depth, 78 lb of weight, and a 1.1/1.6 GPF dual flush with a 28dB soft-close seat claim, it is the only pick that fits three separate small-bathroom problems at once: walkway clearance, install weight, and long-term water use. It is also the only fixture in the shortlist with a written warranty attached to the listing, at 1 year. If chair-height seating matters more than a shallow projection, the **KOHLER San Souci K-5172-HC-0** is the better buy. Its Comfort Height layout is the real difference, not the skirted design or the hidden cord, and you pay the premium price position for it. If you need the shallowest projection you can get, the **WinZo WZ5079** at 22.8 in wins on that single number, but you pay 20 lb in extra weight and give up the warranty. For a rental or a secondary bathroom where cost is the main constraint, the **DeerValley DV-1F52813-VC** shares the winner's footprint at a lower price. Just be careful with the 0.8 GPF half flush on older drain lines. ## FAQ ### Is a compact toilet worth it in a small bathroom? A compact toilet is worth it when the fixture depth is the constraint, which it usually is in a bathroom under 40 square feet. The picks here range from 22.8 in to 27.8 in of projection, a 5 in swing. Five inches of walkway changes whether a vanity door clears the bowl. If your current toilet forces sideways knees, a compact fixture solves that. ### Which compact toilet has the shortest projection? The compact toilet with the shortest projection here is the WinZo WZ5079 at 22.8 in of depth. The two DeerValley one-pieces share second place at 24.6 in. The Kohlers and the Gerber all sit between 27.4 in and 27.8 in. If a door swing or a vanity is fighting for inches, the WinZo is the fixture that wins on that single measurement, though it is heavier to install. ### Are the KOHLER Spacity and San Souci genuinely cordless? The KOHLER Spacity and San Souci are not cordless in the sense of battery-powered smart toilets. Both are standard gravity-flush fixtures with a hidden cord layout, which means the design conceals the power cable of a bidet seat you might add later. If you are searching for a battery-driven smart toilet, none of the picks in this shortlist qualifies, and you should look in a different category entirely. ### DeerValley DV-1F52812 or Kohler Spacity: which should I choose? Choose the DeerValley DV-1F52812 for the shorter 24.6 in projection, the lighter 78 lb install weight, the 1.1/1.6 GPF dual flush, and the 1-year warranty. Choose the Kohler Spacity 28020-HC-0 for the brand's parts network and the hidden cord layout, and accept a 27.4 in projection with 110.2 lb of ceramic to move. The winner is the DeerValley unless the Kohler service network is the deciding factor. ### What is the most common compact toilet buying mistake? The most common compact toilet buying mistake is optimising for flush volume before depth. Buyers see 0.8 GPF and assume smaller water use is always better, then discover the fixture still projects 27 in into a 30 in walkway. Measure the space from the wall behind the tank to the front of the bowl first, then match the flush volume to your drain line's age and slope. Compact toilets earn their place in small bathrooms by giving back inches, not features. The DeerValley DV-1F52812 wins this shortlist because it gives back the most of them without asking for a heavier install, a smaller flush, or a missing warranty in return. Before you order, pull a tape measure across the floor from the wall to where you want the front of the bowl to sit, and add 2 in for the seat overhang. If that number lands under 27 in, the winner or its budget sibling is the safer buy. If you have more room and want chair-height comfort, the Kohler San Souci is the fixture to grow into. *Last updated: September 24, 2026\.
