How the picks were chosen
We started with a pool of 97 toilets listed with a 1.2 to 1.4 GPF specification. From that pool we shortlisted 15 models that cover the most common configurations: two-piece and one-piece, round and elongated bowls, standard, chair, and extra-tall heights, single and dual flush, various rough-in sizes (10, 12, and 14 inches), wall-hung options, and integrated bidet or smart features. Each pick is chosen based on the seller's published specs and brand documentation; we did not test any unit. Prices shown on the page are live from the store listing and may change, so we do not comment on them in the text.
Picking the right one for you
Understanding 1.2 to 1.4 GPF
GPF stands for gallons per flush. The federal standard for toilets is 1.6 GPF, while WaterSense labeled models use 1.28 GPF or less. The range 1.2 to 1.4 GPF includes many high-efficiency toilets that still meet federal guidelines and offer at least a 20 percent water saving compared with 1.6 GPF models. Dual-flush toilets may use a reduced flush of 0.8 or 0.9 GPF for liquids and a full flush of 1.28 GPF or 1.6 GPF for solids. Check the EPA's WaterSense page for more details on efficiency and performance testing.
Round vs. elongated bowls
Round bowls are shorter in depth, typically about 2 inches more compact, which can be a deciding factor in small bathrooms. Elongated bowls offer a larger seating area and are often considered more comfortable, but they require additional clearance in front of the toilet. In this list, both shapes appear across two-piece and one-piece models. Measure your bathroom depth before choosing.
Seat height and ADA considerations
Chair height models typically place the top of the seat around 16 to 17 inches from the floor, which matches a standard chair and makes sitting and standing easier. Extra-tall models can exceed 19 inches, which may be better for tall users or those with mobility needs. The ADA Standards for Accessible Design specify a seat height of 17 to 19 inches for many fixtures, but these rules apply to public or commercial spaces, not necessarily to your home. Still, a chair height toilet can bring comfort without needing a special permit.
Rough-in measurement and compatibility
The rough-in is the distance from the wall behind the toilet to the center of the drain pipe. Common sizes are 10, 12, and 14 inches. Many old homes have 10 or 14-inch rough-ins, while newer construction typically uses 12 inches. Always measure this distance before purchasing. If you pick a toilet without a stated rough-in, confirm with the seller or check your existing setup. A wrong rough-in size will require a different model or an offset flange, which adds complexity.
Single flush vs. dual flush
Single flush toilets use the same amount of water for every flush, usually 1.28 GPF. Dual flush toilets give you a choice: a lighter flush for liquid waste (often 0.8 or 0.9 GPF) and a fuller flush for solids (usually 1.28 GPF or slightly higher). Dual flush can save more water over time, but the mechanism adds moving parts. If you prefer simplicity, a single flush is easier to maintain.
Smart features and bidet integration
Smart toilets can include heated seats, warm water bidets, air dryers, foot sensors, and automatic flushing. Some models combine the toilet and bidet in one unit, eliminating a separate bidet seat. These features require an electrical outlet near the toilet and often a dedicated supply for the bidet. If you are not ready for a full smart toilet, look for a model that is WASHLET+ ready or offers a separate bidet seat later. Wall-hung models also free up floor space but need an in-wall carrier system.
Questions
What does 1.28 GPF mean?
GPF stands for gallons per flush. A 1.28 GPF toilet uses 1.28 gallons of water with each full flush. This is 20 percent less than the federal standard of 1.6 GPF and meets the EPA WaterSense criteria. Many municipalities offer rebates for installing WaterSense labeled toilets, which often fall in the 1.28 GPF range.
Is 1.28 GPF enough to prevent clogs?
Modern 1.28 GPF toilets use engineered flush systems, such as TOTO's Tornado Flush or Kohler's AquaPiston, which are designed to clear waste effectively with less water. The EPA establishes performance criteria for WaterSense labeled toilets, including waste extraction tests. As long as you choose a model from a reputable brand and install it correctly, 1.28 GPF is enough for typical residential use.
How do I measure the rough-in for a toilet?
The rough-in is the distance from the finished wall behind the toilet to the center of the floor drain flange. Remove the old toilet to access the flange, or measure from the baseboard to the center of the closet bolts if the toilet is still installed. Standard sizes are 10, 12, or 14 inches. Most modern homes use 12 inches, but older construction or unusual layouts may require 10 or 14 inches.
What is a chair height toilet?
A chair height toilet has a seat height of roughly 17 to 19 inches, which is similar to sitting in a standard chair. This makes it easier to stand up and sit down, especially for older adults or people with knee or hip issues. Many ADA compliant models are chair height. Extra-tall toilets go beyond 19 inches and may suit taller users, but they can be less accessible for shorter people.
Should I choose a dual flush toilet?
Dual flush toilets offer two flush options: a reduced flush for liquid waste (often 0.8 or 0.9 GPF) and a full flush for solids (usually 1.28 GPF). They can reduce water use compared with single flush models, but they add a more complex valve. If you frequently need the full flush, a single flush may be simpler. Check local water rates and potential rebates before deciding.
Do smart toilets need an electrical outlet?
Yes, integrated smart toilets with features like heated seats, warm water bidets, air dryers, or automatic flushing require a power outlet near the toilet. Some models use a low-voltage transformer, but all need a connection to household power. Plan for a GFCI protected outlet within reach of the toilet if you are considering a smart or bidet-equipped model.
