Best Low Profile Toilet Tanks and Toilets for Compact Bathrooms
A low profile toilet can help when a bathroom has limited vertical clearance or a compact layout, but “low profile” can refer to the tank or the complete toilet. The TOTO Ultramax is explicitly described as a low-profile, one-piece toilet; the PROFLO Jerritt is a tank-only option with a listed depth of 8.5 inches. For buyers comparing compact complete toilets, HOROW and DeerValley offer small-footprint designs, while American Standard’s tank is intended for a specific matching bowl.
| Product | Best For | Key Detail |
|---|---|---|
| TOTO Ultramax | Low-profile one-piece toilet | 1.28 GPF and TORNADO FLUSH |
| PROFLO Jerritt | Tank-only replacement or project | 8.5-inch overall depth |
| American Standard Cadet 3 FloWise tank | Matching Cadet 3 FloWise bowl | 1.28 GPF; bowl sold separately |
| HOROW T0338W | Compact, chair-height toilet | 26-inch overall height |
| DeerValley Compact | Small bathrooms needing a round bowl | 24.5-inch length |
TOTO Ultramax Low Profile Toilet
Best for: Buyers who want a complete toilet specifically identified as low profile, rather than a standalone replacement tank. Its one-piece construction integrates the tank and bowl, which the listed features say is easier to maintain than a two-piece toilet.
The toilet uses 1.28 gallons per flush and a TORNADO FLUSH system. Its CEFIONTECT glaze is described as a smooth surface that helps minimize waste sticking to the ceramic. The package listing also identifies a SoftClose seat.
Limitation: This is a complete one-piece toilet, not a tank-only replacement. Confirm that its dimensions and installation requirements suit the bathroom before choosing it.
PROFLO Jerritt Tank Only
Best for: Buyers seeking a separate tank for a toilet project and comparing front-to-back tank depth. The listed overall depth is 8.5 inches, making this the clearest dimension-specific tank choice in this selection.
This is a 1.28 GPF single-flush tank. Because it is sold as tank only, it lets buyers select a bowl separately. That flexibility can help with a replacement or renovation, provided the chosen tank and bowl are compatible.
Limitation: The listing does not identify a compatible bowl in the supplied details, and a toilet seat is not included. Verify fit and connection requirements before ordering.
American Standard Cadet 3 FloWise Tank
Best for: Owners who already have, or plan to buy, a Cadet 3 FloWise concealed-trap bowl. This 12-inch rough-in tank is designed to pair with that bowl, which is sold separately.
The tank uses 1.28 gallons per flush and includes a 3-inch flush valve, a chrome-finished trip lever, and coupling components. Its defined bowl compatibility makes it a more specific replacement choice than a generic tank-only listing.
Limitation: Do not assume it will fit another toilet bowl. The supplied product details name the Cadet 3 FloWise bowl as the compatible pairing.
HOROW T0338W Compact One-Piece Toilet
Best for: Buyers who need a compact complete toilet with chair-height seating. Its listed dimensions are 26.6 inches deep, 15 inches wide, and 26 inches high, and the 17.3-inch seat height may suit adults seeking a higher seat.
The one-piece design has a dual flush with 1.1 and 1.6 GPF options. A siphon flush and fully glazed 2-inch trapway are listed as design features. Because tank and bowl are integrated, this is a complete fixture rather than a replacement tank.
Limitation: The product is described as compact, but the supplied details do not give a separate tank-height measurement. Check the full toilet dimensions against available clearance.
DeerValley Compact Dual-Flush Toilet
Best for: Buyers prioritizing a shorter toilet footprint for a small bathroom. Its listed dimensions are 24.5 inches long, 13⅜ inches wide, and 28⅜ inches high, with a standard round bowl and skirted design.
The dual-flush system offers 1.1 and 1.6 GPF options. The skirted exterior is designed to reduce hard-to-reach crevices during cleaning. Choose this if floor space matters more than selecting a standalone tank.
Limitation: It is a complete one-piece toilet, not a tank-only product, and its listed height is greater than the HOROW’s 26-inch height.
Buying Guide: How To Choose A Low Profile Toilet Tank
Do you need a tank or a complete toilet?
Start by identifying the part you need. Tank-only models can work for replacement projects, but tank-to-bowl compatibility matters. A one-piece toilet replaces the full fixture and may be a better option when you are changing the bowl as well.
Which measurements should you check?
Measure the available space before shopping. Check the tank’s front-to-back depth and height if clearance is the concern. For a complete toilet, compare the listed overall height, width, and depth with the bathroom layout. Also verify rough-in and connection requirements using the product’s installation information.
Is low profile the same as compact?
No. Low profile generally refers to a lower or less prominent tank or overall fixture, while compact often refers to a smaller floor footprint. Product descriptions may use these terms differently. Compare actual dimensions instead of relying on the label alone.
Should you choose single or dual flush?
A single-flush toilet offers one listed flush volume, such as 1.28 GPF on the PROFLO and American Standard options. Dual-flush models provide separate listed volumes for different flush needs. Choose based on the flush controls and water-use details you prefer.

The DeerValley toilet lists a 24.5-inch length, while the HOROW lists a 26-inch overall height. Compare the dimension that limits your room, along with rough-in and installation requirements.
