Comparison Summary
For a typical 12-inch rough-in where chair-height seating matters, the HOROW T0338W offers the strongest balance: a specified 17.3-inch seat height, elongated bowl, 26.6-inch depth, and 1.1/1.6 GPF dual flush. Its taller seat will not suit everyone. The Swiss Madison St. Tropez SM-1T254HB is a style-forward alternative with black hardware, an elongated bowl, and a removable soft-close seat, but its 27-inch depth needs room. For a narrow bathroom, the DeerValley DV-1F52812-AMZ listing specifies a roughly 24.6-by-13-inch footprint and a round bowl; check the exact variant carefully because the manufacturer’s broader DV-1F52812 page uses inconsistent bowl-shape wording.
The Casta Diva CD-T006 combines a stated 17.5-inch seat height with a 1.0/1.28 GPF dual flush. The DeerValley DV-1F52807 instead keeps operation simple with one 1.28 GPF flush in a short, elongated design. Other useful distinctions are the Los Flexi LFU6-WT-A’s removable seat, the Casta Diva CD-T005’s 17-inch seat height, and the BAYROLL SH-S001’s compact round bowl. The WOODBRIDGE B0940-F-MB merits a look for its smooth exterior and included installation items, provided its rough-in is confirmed. The HOROW HR-ST076W suits buyers who want a left-hand lever rather than top-mounted dual-flush buttons.
Buying Guide
Sizing and Capacity
Measure rough-in from the finished wall behind the toilet to the center of the floor drain, not from the baseboard. Most picks here specify a 12-inch rough-in; that does not make a different rough-in version interchangeable. Next, measure from the wall toward the door and across to nearby fixtures. The 23.5-inch-deep DeerValley DV-1F52807 preserves more front space than the 28.75-inch-deep HOROW HR-ST076W, though both have elongated bowls. A compact round bowl, as listed for the BAYROLL SH-S001, changes the seating experience as well as the footprint. Finally, compare actual seat height—not overall toilet height—with the people using the bathroom.
Feature Tradeoffs
Dual flush gives you a lower-volume choice for liquid waste, but the full-flush number still matters. The HOROW T0338W lists 1.1/1.6 GPF; the Casta Diva CD-T006 lists 1.0/1.28 GPF. Neither pair of numbers alone establishes how well a particular installation will flush. If you would rather use one control without choosing a setting, the DeerValley DV-1F52807 offers a listed 1.28 GPF single flush. Skirted sides reduce exposed contours to wipe, while quick-release seats on models including the Swiss Madison St. Tropez SM-1T254HB give access around the seat fittings. A smooth exterior does not remove the need to clean the bowl and hinges.

Key Specs to Compare
Keep four figures side by side: rough-in, overall depth and width, seat height, and GPF for each flush mode. For example, the HOROW T0338W specifies a 17.3-inch seat height; the 26-inch overall height in its dimensions describes something else. The Los Flexi LFU6-WT-A listing uses both 17-inch bowl-height and 17.3-inch seat-height wording, so resolve that distinction before ordering for a particular user. Treat advertised MaP scores and WaterSense language as claims to check for the exact model rather than conclusions drawn from GPF. If a label or certification is essential, verify the exact model and configuration in current documentation.
Setup and Handling Considerations
A one-piece toilet arrives as a combined bowl and tank, so plan how to carry and position the entire fixture through doorways and around nearby cabinetry. The WOODBRIDGE B0940-F-MB listing specifies a weight over 100 pounds and includes a wrench for its narrow mounting access; the DeerValley DV-1F52812-AMZ is listed at 78 pounds. Check the box contents for your exact order before arranging installation. Several listings include a wax ring and floor bolts, but a water supply line is not established as included across the shortlist. The BAYROLL SH-S001 also calls for a check of its angle-valve position. Confirm both the drain fit and water-supply access before removing the old toilet.
Maintenance and Longevity
Choose cleaning access you can use. The DeerValley DV-1F52807 and Casta Diva CD-T005 list quick-release seats, which can be removed to reach the area beneath the hinges; the HOROW T0338W lists a soft-close seat but not that same release feature. Skirted sides avoid exposed trapway curves, although their concealed fasteners can make access during installation less direct. For future repairs, identify the exact seat and flush components rather than assuming parts from another finish or model will fit. A stated warranty, such as the one-year limited coverage listed for the HOROW T0338W, is worth checking for its actual terms, not treating as a promise of service life.
Reliability Signals
Exact-model documentation is more useful than a broad family description. Swiss Madison publishes information for the SM-1T254HB and identifies replacement components, which helps with future parts checks. Manufacturer information for the DeerValley DV-1F52812 line lists dimensions and rough-in variants, but its bowl-shape wording conflicts with the compact round-bowl listing; verify the delivered DV-1F52812-AMZ configuration. Also distinguish a measured seat height from an accessibility label. Chair-height or ADA wording on a product page does not establish that your completed bathroom meets applicable accessibility requirements. Confirm critical dimensions and any required certification for the exact fixture.
How to Compare Reviews
When reading owner feedback, match the model identifier, rough-in version, and kit before drawing a conclusion. A comment about a 10-inch rough-in variant cannot settle how the 12-inch HOROW T0338W will fit. For the DeerValley DV-1F52812-AMZ, look for enough detail to establish whether the writer received the round-bowl configuration in question. Separate delivery damage, installation fit, seat hardware, and flush observations: each points to a different buying risk. Flush accounts are most useful when they describe the selected setting and installation conditions, while seat-comfort accounts should identify the user’s preferred height and bowl shape.
Common Mistakes
Do not order by appearance before measuring the drain and door swing. A shallow footprint cannot correct a mismatched rough-in, and a narrow tank cannot create knee room if the bowl projects too far. Do not confuse the lower dual-flush setting with the full-flush volume: the Swiss Madison St. Tropez SM-1T254HB lists 1.1 GPF for the reduced flush and 1.6 GPF for the full flush. Avoid treating every 17-inch measurement as a seat measurement or every included installation kit as including a supply line. Finally, choose between round and elongated seating deliberately; the shortest-looking model is not automatically the most comfortable one.
Frequently Asked Questions
How do I know whether I need a 10-inch or 12-inch rough-in?
Measure from the finished wall behind the existing toilet to the center of the floor drain or closet bolts. Compare that measurement with the exact model and variant you intend to buy; do not assume a differently sized version is in the selected listing.
Is chair height the same as ADA compliance?
No. Chair height describes a taller seating position, while accessibility compliance depends on the applicable requirements and the completed installation. Check the exact seat height and relevant documentation if compliance matters.
Will a 1.28 GPF toilet always use less water than a dual-flush model?
Not on every use. The DeerValley DV-1F52807 lists 1.28 GPF for its single flush; a dual-flush model can use less on its reduced setting and more on its full setting. Compare both stated settings with how the toilet will be used.
Do these modern toilets need an electrical outlet?
These selections are conventional toilets, not integrated electric bidet or smart-toilet models. Still, check the exact configuration before purchase if a listing offers different seat packages.
Final Recommendation
Choose the HOROW T0338W if your bathroom has a confirmed 12-inch rough-in and you want an elongated, 17.3-inch-high seat in a manageable 26.6-inch-deep one-piece design. If floor space matters more than taller seating, choose the shorter DeerValley DV-1F52807 instead; it retains an elongated bowl but replaces dual flush with a straightforward 1.28 GPF single flush.
