This is one of the few compact toilets on the market built for a 10-inch rough-in, making it a lifesaver for old homes or tight layouts where the drain is closer to the wall than modern standards allow. The 25-inch depth and 13.4-inch width are nearly identical to the HOROW models, but the upgraded urea-formaldehyde seat is noticeably denser and more resistant to scratches and yellowing than standard polypropylene seats. Owners consistently report that the seat feels premium and does not shift during use.

The siphon-jet flush with a 2-inch fully glazed trapway produces a strong, quiet evacuation that rarely requires a second flush. The average consumption clocks in below 1.28 GPF by alternating between the 1.1 and 1.6 options, which saves water without compromising clearing power. The skirted sides and high-temperature-fired ceramic (2246°F) resist staining, so the bowl stays white with minimal scrubbing. Several buyers noted that the pre-installed internal components and side-mounting holes made installation straightforward even for a first-timer using basic tools.

The only concession is the round-front bowl geometry. While the seat height is a comfortable 16.5 inches, those accustomed to elongated seats will find the overall sitting area slightly shorter. The included quick-release function allows the seat to detach with a press for deep cleaning, and the soft-close hinge operates at a hush that won’t wake anyone at night. For anyone needing a true 10-inch rough-in toilet, this is the most reliable option available right now.

This smart toilet packs a full-feature bidet, heated seat, and auto-open lid into a one-piece tankless body that measures just 26.7 inches deep and 15.35 inches wide — dimensions that fit comfortably in a standard compact footprint. The low-profile design eliminates the traditional tank, gaining a few extra inches in depth while adding a hidden foam shield that activates when you sit, preventing splash-back and trapping odors before they spread. The built-in ceramic aluminum oxide heating element delivers warm water within a second of pressing the spray button, and the drier blows warm air at adjustable temperature.

The 12-inch rough-in installation requires a nearby GFCI outlet because the unit draws power for the heated seat, bidet spray, and LED display. The foot sensor lets you open the lid and seat without touching anything, and the auto-flush activates when you step away. Multiple buyers reported that after a full year of use, the flush mechanism showed no wear, the heated seat stayed consistent, and the water filtration system prevented mineral build-up in the spray nozzles. The ambient starlight lighting is a surprisingly useful addition for nighttime trips because it illuminates the bowl without blinding you.

The trade-off is that this toilet is about an inch wider than some ultra-compact units, so verify the 15.75-inch width against your existing space. The included remote control is intuitive, but the instruction video covers a slightly different model variant, so be prepared to troubleshoot the hidden bolt locations during install. For buyers who want smart features without expanding the toilet’s footprint, this unit delivers an impressive feature set in a space that a standard one-piece would occupy.

This is the elongated option for buyers who refuse to sacrifice bowl length but still need a compact overall depth. At 28.15 inches deep and 14.17 inches wide, it is longer than a round compact unit, but the 16-7/8-inch seat height and elongated shape provide a full-size seating experience that feels indistinguishable from a standard toilet. The key space-saving trick is the one-piece skirted design — it eliminates the gap between tank and bowl, reducing the visual bulk and making the unit appear more streamlined in a small room.

The dual-flush system (1.1/1.6 GPF) uses a 2-inch fully glazed trapway that buyers repeatedly describe as “self-cleaning” — waste slides off the surface easily, and the bowl rarely stains between cleanings. The side-access ports for the mounting bolts are a major convenience compared to rear-bolt designs because you can reach the nuts with a standard crescent wrench without contorting your arm. Several installers commented that they finished the job solo in under 30 minutes thanks to these side ports and the clear instruction sheet.

The biggest downside is the weight — 99 pounds makes this a two-person lift during installation. The glossy ceramic surface is scratch-resistant, but the bowl holds slightly less standing water than some users prefer, which can lead to more visible marks after heavy use. The included soft-close seat is a standard polypropylene unit, adequate but not as premium as the UF seat found on the SOTOMO. If you have the additional 3 to 4 inches of depth allowance, this elongated compact offers the best seating comfort in the category.

Measuring just 24 inches deep and 14 inches wide, the Swiss Madison Sublime II is the shortest compact toilet on this list, making it ideal for half-baths where every inch of floor clearance matters. The round-front bowl and standard seat height (around 16 inches) sit lower than chair-height models, but the reduced overall length means you can install this unit in a space that would reject every other option here. The non-porous scratch-resistant ceramic body is fired at high temperature to resist hairline cracks and surface etching from abrasive cleaners.

The fully skirted trapway hides the plumbing completely, giving the toilet a clean furniture-like appearance. The dual-flush buttons sit on top of the tank lid and allow a 1.1 or 1.6 GPF selection. Many buyers praised the finishing quality — the glazing is uniform inside the trapway, which prevents waste from sticking and reduces the need for plunger intervention. The soft-close seat is quick-release, so you can pop it off for deep cleaning around the hinge area without needing to unscrew anything.

The downsides are centered on the installation experience. The included wax ring and closet bolts are undersized, and several buyers reported that the bolts did not fit properly with their flange. The rear access holes are tight — you will need a thin 9/16-inch socket or a small wrench to reach the nuts. The seat itself is a standard plastic model; some buyers found it uncomfortable enough to replace it after the first week. For the shortest possible depth, though, this unit sets the standard.

DeerValley’s DV-1F52812 offers a slightly different aesthetic than the DV-1F026, with a gold flush button and a round bowl that measures 24.5 inches deep — about 3.5 inches shorter than the elongated cousin. This makes it a better fit for bathrooms where the door swing overlaps the toilet area. The 13.38-inch width is also narrower than the standard 14-inch width, so you can tuck it next to a vanity without rubbing knees against the cabinet.

The flush system uses the same 1.1/1.6 GPF dual technology as the other DeerValley models, but several buyers noted that the flush on this unit felt weaker straight out of the box. The issue appears to be related to the standard 7/8-inch supply line — the toilet’s fill valve is designed for a 1/2-inch connection, and using the larger line without the included adapter reduces the flow pressure. Once the correct adapter was fitted, the flush cleared the bowl reliably. The soft-close seat operates at a low 28 dB, which is genuinely quiet compared to the clatter of standard seats.

The included installation kit comes with a wrench, which is a nice touch for weekend DIYers, but some buyers felt that the overall build quality of the ceramic did not match the price bracket. A few units arrived with rough edges around the bolt holes, though none reported functional leaks. The gold button adds a touch of warmth to the bathroom design, but it is not removable if you prefer a uniform chrome look. For a round-bowl compact that fits very tight corners, this unit works well once the supply line is configured correctly.

The HOROW HWMT-8733S is the entry-level compact that balances cost with essential performance. The 25-inch depth and 13.1-inch width are nearly identical to the SOTOMO, but the seat is a standard polypropylene unit instead of the stronger UF material. The chrome-side flush button adds a modern accent that blends with most bathroom fixtures. The one-piece ceramic body has a fully skirted trapway, so the underside is as smooth as the front — no hard-to-reach corners for dust to collect.

The dual-flush system is functionally identical to the non-S variant, offering a 1.1 GPF light flush and a 1.6 GPF full flush. The siphon action is quiet and, according to most buyers, clears solid waste without needing a second flush. The included wax ring and floor bolts are standard quality and sufficient for a straightforward install. The soft-close seat closes slowly enough that it does not slam even if dropped from a full-open position.

The main complaints revolve around the seat fastening system. Multiple buyers reported that the seat loosens every two to three weeks and needs to be retightened, which becomes annoying over time. A few installers also noted that the rear bolt access is extremely limited — the bolts sit at the back of the chassis with very little room to fit a wrench. If you have larger hands or want a tool-less installation, this may be a challenge. For a budget-friendly compact that covers the basics, the HOROW S is a solid starter, but plan for periodic seat maintenance.

The HOROW HWMT-8733 (the non-S variant) shares the same 25 x 13.4-inch footprint as the S version but swaps the chrome button for a standard dual-flush actuator. The 16.5-inch seat height places it at the lower end of standard height, which can be a benefit for shorter users who find chair-height toilets uncomfortable. The tank refills noticeably faster than many competitors, according to buyers, which reduces wait time between back-to-back flushes in busy households.

The round-front bowl and compact tank shape optimize the tiny floor footprint. Buyers consistently note that the toilet looks modern and minimalist — no exposed trapway or bulky side rails. The dual-flush system offers the same 1.1/1.6 GPF split, and the siphon action is reported to be powerful enough to handle heavy loads without clogging. The soft-close seat and lid are a welcome standard inclusion at this level.

The downside is that the seat quality is the weak link. Several customers reported that the seat feels flimsy and moves noticeably during use, to the point where it nearly slid off. The manufacturer initially resisted replacing the seat, although some buyers eventually received an upgraded unit after escalation. A smaller number of owners experienced cracks in the ceramic body after the first winter in a seasonal home, even with proper winterization. If you are willing to replace the seat with a third-party UF model, the basic toilet platform is sound and very compact.
