3 Best Low Flow Toilets 2025 in the United States

The TOTO Drake Two-Piece Elongated Toilet offers several advantages for those seeking a low-flow toilet. Its 1.6 gallons per flush (GPF) aligns with water-saving goals without compromising performance, thanks to its TORNADO FLUSH technology which effectively cleans the bowl using a circular water motion. The CEFIONTECT glaze is a nice touch, reducing the frequency of cleaning by preventing waste buildup. This toilet features a standard height, which might be preferable for those not interested in a taller, universal height option.

The elongated bowl is designed for comfort and fits well with modern bathroom décor, while its cotton white color adds a stylish touch. Installation should be relatively straightforward due to its compatibility with 12-inch rough-in installations, although you will need to purchase a wax ring, flange bolts, and water supply lines separately. However, it lacks the WaterSense certification, which might be a consideration for those looking for the highest water efficiency standards.

At 89 pounds, it is somewhat heavy, which could make installation more challenging for some. Additionally, while the toilet includes the tank, bowl, and hardware, the seat must be bought separately, adding to the overall cost. Despite these minor drawbacks, the TOTO Drake toilet is a solid choice for anyone looking to balance performance, design, and water efficiency in their bathroom.

The American Standard 288DA114.020 H2Optimum Two-Piece Toilet is an efficient choice for those looking to save water. With a low water consumption of 1.1 gallons per flush (GPF), this toilet stands out in water efficiency, making it environmentally friendly and economical. It also boasts a high Maximum Performance (MaP) score of 1,000 grams, ensuring a powerful flush despite the low water usage. Additionally, it has a WaterSense certification, confirming its efficiency in conserving water.

The PowerWash rim feature helps in maintaining the cleanliness of the bowl by scrubbing it with each flush, and the EverClean surface prevents stain and odor buildup, making maintenance easier. However, the seat is sold separately, which could be an inconvenience for some users. The toilet is floor-mounted and made of ceramic, ensuring durability. Its round bowl shape and standard height make it a good fit for most bathrooms, although some might prefer an elongated bowl or a different height for comfort.

Installation is relatively straightforward, but at 72.1 pounds, it may require some assistance. With its white finish and inclusion of color-matched bolt caps, it offers a clean and cohesive look. The toilet comes with a limited lifetime warranty on the chinaware and a 5-year warranty on mechanical parts, adding a layer of assurance for buyers. This toilet is a solid pick for those prioritizing water efficiency and ease of maintenance, though some additional purchases and considerations for comfort might be necessary.

The Kohler K-5481-96 Highline Comfort Height toilet is a solid choice for those looking for a low-flow option. With a water-saving 1.28 gallons per flush (GPF), it meets WaterSense certification criteria, making it an environmentally friendly option. The Class Five Flush Technology ensures powerful and effective flushing, reducing the need for multiple flushes, which further saves water.

The round-front bowl design is compact, making it suitable for smaller bathrooms and powder rooms. Additionally, the comfort height feature is beneficial for most adults, offering easier sitting and standing, akin to chair height seating. This toilet is made from durable vitreous china, ensuring long-lasting performance. However, it is a two-piece toilet, which can sometimes be more challenging to clean due to the seam between the tank and the bowl. Its installation is floor-mounted, which is typical, but it may require professional help if you're not familiar with toilet installations.

The product also includes a left-hand trip lever, which is user-friendly. The color 'Biscuit' is a neutral tone but may not match all bathroom decors. At 84.8 pounds, it is relatively heavy, so you might need assistance during installation. While it's not the top-ranked toilet, it does offer good value for those specifically needing a low-flow, comfort-height, and space-saving option. The one-year limited warranty from KOHLER provides some peace of mind regarding its quality.
