How the picks were chosen
We reviewed 97 toilet listings with a specified flush volume of 1.28 gallons per flush. From these, we shortlisted 15 models that represent a range of features: bowl shape (elongated or round), construction (one-piece or two-piece), seat height (standard, chair, or extra tall), rough-in size, flush type (single or dual), and extra features like bidet integration or wall-hung mounting. Each pick is based exclusively on the seller's stated specifications and manufacturer information. Prices are read live from the store listing and are not used as a selection criterion. We have not tested any of these units ourselves.
Picking the right one for you
Understand 1.28 GPF and WaterSense
A 1.28 gallons per flush toilet uses 20 percent less water than the federal standard of 1.6 GPF. The EPA's WaterSense program certifies toilets that meet strict performance and efficiency criteria, including waste extraction and bowl cleaning tests. When you see 1.28 GPF, you're looking at a fixture that can significantly cut household water use, potentially saving thousands of gallons annually. For dual-flush models, the reduced mode uses even less water, though both modes stay within the 1.28 GPF limit.
Bowl shape: elongated vs. round
Elongated bowls are about 2 inches longer, offering more comfort and a modern look, but they require more floor space. Round bowls are compact and fit better in small bathrooms or powder rooms. Consider the available clearance and your personal preference. In our list, elongated models dominate, but round options like the Kohler Highline and TOTO Entrada address space-constrained settings.
One-piece vs. two-piece construction
One-piece toilets mould the bowl and tank into a single unit, reducing crevices that collect dust and easing cleaning. Two-piece toilets separate the tank from the bowl, which can be simpler to handle and replace parts. One-piece models like the Kohler Cimarron offer a streamlined silhouette, while two-piece designs such as the TOTO Drake are often more budget-friendly and widely available.
Seat height and accessibility
Seat height affects comfort, especially for seniors or those with mobility challenges. Standard toilets sit around 15 inches, chair height models range from 16.5 to 18 inches, and extra tall options exceed 19 inches. The ADA recommends a seat height between 17 and 19 inches from the floor for accessible facilities. Look for labels like 'chair height' or 'ADA compliant' to ensure the toilet meets your needs.
Rough-in size and installation
The rough-in is the distance from the wall to the center of the floor drain, commonly 10, 12, or 14 inches. Before purchasing, measure this gap to avoid a mismatched fixture. Most homes use a 12-inch rough-in, but older properties may have 10 or 14. Our picks include options for each size, such as the DeerValley compact with 12-inch rough-in and the Signature Hardware Bradenton with a 14-inch rough-in.
Dual flush and extra features
Dual-flush toilets offer two buttons or levers: a reduced flush (usually 0.8 or 0.9 gallons) for liquid waste and a full flush (1.28 gallons) for solids. This can further lower water consumption. Smart toilets add bidet functions, heated seats, and automatic flushing, but they require an electrical outlet and sometimes a dedicated water line. Weight these conveniences against installation complexity when deciding.
Questions
What does 1.28 GPF mean?
GPF stands for gallons per flush. A 1.28 GPF toilet uses 1.28 gallons of water per flush, which is 20 percent less than the federal maximum of 1.6 GPF. This reduction can save thousands of gallons of water per year per household. The EPA's WaterSense program certifies that toilets meeting this flow rate also satisfy performance requirements for waste removal.
Are all 1.28 GPF toilets WaterSense certified?
Not automatically. A toilet must be independently tested and meet EPA's performance criteria to earn the WaterSense label. While many 1.28 GPF models are certified, you should verify each product's certification. In our picks, we relied on the seller's specifications; we did not assume certification for any model. Always check the manufacturer's documentation for WaterSense certification.
Can I install a 1.28 GPF toilet in an older home?
Yes, as long as the rough-in measurement matches your existing drain. Older homes often have 10 or 14-inch rough-ins, while newer ones typically use 12 inches. Measure from the wall to the center of the closet flange before purchasing. Some models, like the Signature Hardware Bradenton, specifically support 14-inch rough-ins.
What is the difference between chair height and extra tall?
Chair height typically refers to a seat height between 16.5 and 18 inches, aligning with the ADA's recommended 17-19 inch range. Extra tall bowls exceed 19 inches, often around 20-21 inches. These are useful for very tall individuals or those with limited knee flexion. In our list, the Los Flexi and Swiss Madison Classe offer 21-inch heights.
Do smart toilets need special plumbing or electrical work?
Smart toilets with bidet features require both a cold water supply and a standard electrical outlet (typically 110V) near the toilet. Some models also need a drain connection for the bidet spray. Installation might involve adding an outlet, which could require a licensed electrician. Verify your bathroom's existing hookups before choosing a smart model like the TOTO Drake Washlet+.
