TOTO Drake Two-Piece Elongated 1.6 GPF TORNADO FLUSH Toilet with CEFIONTECT, Cotton White - CST776CSG#01

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.

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.

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.

Buying Guide for the Best Low Flow Toilets

Choosing the right low-flow toilet can make a significant difference in water conservation and overall bathroom efficiency. Low-flow toilets are designed to use less water per flush compared to traditional toilets, which helps in reducing water bills and conserving water resources. When selecting a low-flow toilet, it's important to consider several key specifications to ensure you get the best fit for your needs. Here are the main specs to look at and how to navigate them.
Gallons Per Flush (GPF)Gallons Per Flush (GPF) measures the amount of water used each time the toilet is flushed. This spec is crucial because it directly impacts water usage and efficiency. Low-flow toilets typically use 1.6 GPF or less, with some models using as little as 1.28 GPF or even 0.8 GPF for dual-flush systems. If water conservation is your top priority, opt for a toilet with a lower GPF. However, ensure that the flushing performance is still effective to avoid multiple flushes.
Flushing TechnologyFlushing technology refers to the mechanism used to clear waste from the bowl. Common types include gravity-fed, pressure-assisted, and dual-flush systems. Gravity-fed toilets use the natural force of gravity to flush, making them quieter and simpler. Pressure-assisted toilets use compressed air to forcefully flush water, which can be more effective but noisier. Dual-flush toilets offer two flush options: a lower volume flush for liquid waste and a higher volume flush for solid waste. Choose a flushing technology that balances water efficiency with effective waste removal based on your household's needs.
Bowl ShapeThe shape of the toilet bowl can affect comfort and space usage. The two main shapes are round and elongated. Round bowls are more compact and fit better in smaller bathrooms, while elongated bowls offer more comfort due to their extended shape. Consider the size of your bathroom and your personal comfort preferences when choosing the bowl shape.
HeightToilet height can impact comfort, especially for taller individuals or those with mobility issues. Standard height toilets are around 15 inches from the floor to the seat, while comfort height (or chair height) toilets are typically 17 to 19 inches high. Comfort height toilets are easier to sit down on and stand up from, making them a better choice for older adults or people with disabilities. Choose a height that suits the needs of all household members.
WaterSense CertificationWaterSense is a certification provided by the U.S. Environmental Protection Agency (EPA) for products that meet specific water efficiency and performance criteria. Toilets with the WaterSense label use at least 20% less water than standard models while maintaining high performance. Opting for a WaterSense certified toilet ensures you are choosing a product that is both water-efficient and effective.
Ease of Installation and MaintenanceConsider how easy the toilet is to install and maintain. Some models come with features like quick-release seats, easy-to-clean surfaces, and simple installation processes. If you plan to install the toilet yourself, look for models with straightforward instructions and all necessary hardware included. Additionally, consider the ease of cleaning and maintaining the toilet to ensure long-term satisfaction.
