The Bazyths ZY695A Mini packs a full smart bidet system — heated seat, auto open/close lid, foot sensor flush, warm air dryer, and rear/front wash — into a 22.83-inch shallow depth that rivals the shortest non-electric options. The built-in tank removes any water pressure dependency, so even homes with low supply lines get consistent 1.03 GPF flushes without holding the handle down. The high-density foam shield adds splash and odor control that most standard compact toilets simply do not offer at any projection length.

Installation requires a GFCI outlet near the toilet, and the included remote controls all bidet modes, temperature adjustments, and the RGB nightlight. The auto-open sensor is slightly less responsive than high-end TOTO washlet setups, but the side kick-flush sensor works reliably even when standing. The seat width is notably wider than typical round compact models — 3.54 inches wider — which makes the bowl feel spacious even though the total depth stays under 23 inches.

The primary downside is quality control variance: some units arrive with loose lid attachments or crimped supply lines, though the seller offers fast replacement support. The manual is poorly translated, and the ambient light settings require a specific long-press pattern to unlock full color options. For anyone wanting a truly hands-free, feature-complete smart toilet that fits the tightest floor plans, this delivers the broadest feature set at its projection length.

The EPLO U8PRO marries the convenience of an auto-open, auto-flush smart bidet with a 1000-gram MaP flush score that few compact-oriented toilets achieve. The elongated bowl projects 27.63 inches from the wall — not the shortest on this list, but the ADA-compliant 17.3-inch seat height and the built-in booster pump make it a standout for homes with unstable water pressure that still demand a powerful siphon-jet rinse. The dual-flush system runs 1.6 GPF full and 1.1 GPF half, and the hidden tank keeps the silhouette clean.

The warm air dryer cycles through four temperature levels up to 131°F, and the deodorizer actually neutralizes odors rather than just masking them — a rare feature in any compact toilet. The rechargeable backup battery ensures the auto-flush and bidet functions work during power outages, which is not standard on most smart units. The self-cleaning wand extends and retracts with oscillating and pulsating wash modes, and the remote control offers individual user presets for two different household members.

At 45 kilograms (roughly 99 pounds), the U8PRO is heavy enough to require two-person installation and professional help if your bathroom lacks a dedicated outlet. Some users report that the auto-lid sensor can fail after power restoration, requiring a re-initialization via the remote — but EPLO support responds within the same day, even on weekends. The PP seat feels slightly less substantial than the UF seat on the SOTOMO, but the overall build quality and fully ceramic bowl justify the premium investment for a primary bathroom smart toilet.

The WinZo WZ5079B claims the title for the shortest projection on this list at exactly 22.8 inches from the wall, making it the best option for extremely narrow bathrooms where every inch of floor space matters. The 3.15-inch diameter trapway is oversized for a compact toilet, significantly reducing clog risk despite the shortened bowl. The double cyclone flushing system uses two jet streams rather than traditional rim holes, giving a full bowl rinse with each flush while keeping the exterior profile clean and skirted.

The matte black finish adds a contemporary look that stands out against standard glossy white, and the concealed trapway makes daily wiping effortless since there are no exposed pipes or crevices. The included soft-close seat uses a quick-release mechanism for removal during deep cleaning. The seat itself is thin and flexes slightly under pressure, and some users note a clicking sound until rubber bumpers are added. The round bowl shape reduces the seating surface, so larger individuals may find the seat smaller than expected — the depth savings come at the cost of surface area.

Installation is tricky because the bolts are concealed and the side access holes are small, limiting the size of wrench that can fit. The dual-flush buttons are offered in chrome, gold, or black to match the finish, but the flush performance is gravity-based with a 2-inch valve, so the 1.6 GPF full flush handles solids well while the 0.8 GPF light flush occasionally leaves residue. Customer service from WinZo is responsive and replaced a unit with a manufacturing defect quickly. For the absolute smallest footprint available, this is the only real choice.

The TOTO Drake with Tornado Flush is the reference standard for raw flushing performance in a two-piece configuration that fits a 10-inch rough-in — an essential option for older homes where the standard 12-inch rough-in simply will not work. The CEFIONTECT glaze creates an ultra-smooth ceramic surface that prevents waste from bonding, reducing the frequency of scrubbing. The 3-inch flush valve paired with a fully glazed 2-inch trapway delivers a siphon jet that clears the bowl in a single 1.6 GPF cycle without double-flushing.

The Universal Height (ADA-compliant) seat makes sitting and standing easier for seniors and taller users, and the included SoftClose seat prevents slamming. The elongated bowl adds 1.5 inches of seating length over a round bowl, improving comfort during longer sits. The Drake ships in three separate pieces (tank, bowl, seat), which keeps the boxes manageable but means you need to connect the tank to the bowl yourself — a straightforward process if you follow the included instructions. The left-hand trip lever is classic and reliable, and the entire assembly is backed by TOTO’s long reputation for durability.

At 28.5 inches deep, the Drake is longer than the ultra-compact models, so it only fits if your bathroom has at least that much floor clearance from the wall. The 10-inch rough-in version is less commonly stocked than the 12-inch version, so availability can fluctuate. The included plastic seat feels cheap relative to the quality of the bowl and tank, and many owners replace it with a wooden or UF seat immediately. For absolute flush reliability in a compact rough-in configuration, the TOTO Drake remains the benchmark that other toilets are measured against.

The Swiss Madison Sublime II balances a 24-inch bowl depth with a fully skirted one-piece design that hides the trapway for a cleaner aesthetic — a strong mid-range option for buyers who want modern styling without paying for smart bidet features. The dual top-flush buttons let you choose 1.1 GPF for liquid or 1.6 GPF for solids, and the fully glazed 3-inch diameter trapway keeps water flowing freely even with the shorter projection. The scratch-resistant, non-porous ceramic surface resists staining and cleans easily with standard bathroom cleaners.

The soft-close, quick-release seat detaches with a push of a button for deep cleaning, and the round bowl shape saves space while still offering standard height (15–17 inches) that works for most users. The included wax ring, bolt kit, and cover caps cover the essential installation hardware, though the access holes are small and require a slim socket or deep-well wrench to reach the mounting nuts. The skirted design has no exposed plumbing, so there are no hard-to-reach crevices for dirt to accumulate.

The primary complaints center on the installation instructions, which are minimal and may assume previous plumbing experience. Missing closet bolts or an undersized wax ring are occasional QC issues, so having a waxless gasket as a backup is prudent. The seat, while functional, is plastic and does not feel as solid as the UF seat on the SOTOMO. For the price, the Sublime II delivers a reliable one-piece compact toilet with solid flush performance and a clean exterior that fits both modern and traditional bathrooms.

The HOROW HT1000 is designed for bathrooms where side clearance between walls or vanities is the primary constraint — at 13.1 inches wide, it is the narrowest toilet in this lineup. The one-piece round bowl measures 25 inches deep and 28.3 inches tall, keeping the silhouette trim while maintaining a standard round seating area. The dual-flush system averages 1.28 GPF across full and light cycles, saving water without sacrificing the siphon flush that clears the 2-inch fully glazed trapway reliably.

The skirted design eliminates grooves and corners that trap dirt, and the self-cleaning ceramic surface fights stain buildup between scrubbing sessions. The soft-close PP seat closes silently and uses a stainless steel hinge that resists corrosion over time. The side access holes are larger than those on the Swiss Madison, making floor bolt installation easier for DIY homeowners. The package includes a wax ring, pre-installed flush valve, and floor bolts, though some users prefer to swap the wax ring for a waxless gasket for a cleaner seal.

The standard round bowl means less legroom for taller users, and the seat itself is noticeably less substantial than UF seats — it bends slightly under heavy forward pressure. The flush button placement on the top tank can be awkward to reach if the toilet is tucked into a corner. Customer service from HOROW is notably responsive, sending replacement parts quickly if the seat hinge or lid has cosmetic defects. For extremely narrow layouts where a wider bowl would interfere with a vanity or door swing, the HT1000 is purpose-built to fit.

The SOTOMO MY-2133 distinguishes itself from the crowd of compact one-piece toilets by equipping an upgraded UF (urea-formaldehyde) seat instead of the standard PP seat found on most competitors in this price tier. UF is heavier, feels more like solid wood, resists scratches and yellowing, and will not warp in humid bathroom environments — a meaningful upgrade for daily use. The bowl projects 25 inches from the wall with a 13.4-inch width, and the 16.5-inch seat height lands in the sweet spot between standard and ADA comfort height, making it accessible without feeling towering in a small room.

The siphonic dual-flush system uses a 2-inch fully glazed trapway fired at 2246°F for an ultra-smooth surface that resists staining. The full flush runs 1.6 GPF and the partial flush uses 1.1 GPF, averaging under 1.28 GPF. The skirted one-piece design has no seams or exposed plumbing, so wiping down the exterior takes seconds. The quick-release seat hinges lift off entirely for deep cleaning around the bowl rim — a feature that becomes indispensable over the life of the toilet. Pre-installed parts and step-by-step video guidance reduce installation friction for first-time DIYers.

The seat is the standout feature here, and it is the main reason to choose the MY-2133 over cheaper alternatives. However, the round bowl still limits total seating area, and some users note that the front of the seat curves inward more than elongated options, which can feel confining for wider builds. Customer service from SOTOMO is excellent — the company offers fast 24-hour support and has a reputation for replacing damaged units without hassle. For buyers who prioritize seat longevity and a solid, non-plastic feel, this is the best mid-range compact choice on the market.

The HOROW T0338W breaks from the round-bowl convention of most compact toilets by offering an elongated shape on a one-piece body that measures 26.6 inches deep — slightly longer than the pure compact options but still shorter than standard 28- to 30-inch models. The 17.3-inch ADA chair height seat makes this the best option in the mid-range for seniors or anyone who struggles to lower onto a standard-height bowl. The elongated shape provides the extra legroom that round bowls lack, making longer sits more comfortable without adding excessive depth.

The siphonic flush uses a 2-inch fully glazed trapway with dual 1.1/1.6 GPF buttons, and the flush valve pre-installed in the tank simplifies setup. The side access openings are large enough to fit a standard wrench, which cuts installation time compared to the tight hand holes on the Swiss Madison or WinZo. The soft-close PP seat is screw-fixed to the bowl to prevent shifting, and HOROW backs the unit with lifetime after-sales support and a one-year warranty. The all-white finish with a chrome flush button keeps the look clean and neutral.

The flush performance is slightly less aggressive than the TOTO Tornado, and some users note that the light flush struggles with large solids if the water level is not set correctly. The seat cover closes very slowly — over 30 seconds in some cases — which can be annoying in a busy household. The toilet is heavy at 99 pounds, so two-person lift and placement is mandatory. For buyers who need the accessibility of an ADA-height elongated bowl but cannot fit a standard 28-inch projection, this is the best elongated compromise available.

The Kohler Highline 3889-0 is the only two-piece toilet in this lineup, and it earns its place by offering a 10-inch rough-in option for older homes where the floor flange sits closer to the wall than modern standards. The elongated bowl provides the extra 1.5 inches of seating length that makes daily use more comfortable, while the 1.28 GPF single-flush siphon system keeps water consumption low without requiring a dual button. The vitreous china construction delivers Kohler’s standard durability — these toilets hold up for decades with proper care.

Because it is a two-piece design, the Highline ships in two boxes: one for the tank and one for the bowl. This makes handling and transport easier compared to 99-pound one-piece units, though you do need to bolt the tank to the bowl during installation. The comfort-height rim (roughly 16.5 inches with the included seat) meets ADA guidelines and suits most adults well. The clean, simple design matches traditional bathroom décor without looking dated, and the left-hand trip lever is intuitive for both children and adults. The plastic seat is functional but basic — most owners upgrade it immediately.

The 29.5-inch depth is the longest in this comparison, so the Highline only fits spaces where the floor clearance from the wall exceeds that number. The single-flush 1.28 GPF is less flexible than the 1.1/1.6 dual-flush options on other toilets. shipping damage is a known risk: the tank and bowl are packed separately but the packaging is minimal, and some units arrive with cracks. For a budget-conscious buyer who needs a 10-inch rough-in from a reliable brand and can accommodate the longer projection, the Highline delivers simple, predictable performance.
