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.
