Buying Guide for the Best Dual Flush Toilets

Choosing the right dual-flush toilet can significantly impact your water usage and overall bathroom experience. Dual-flush toilets offer two flushing options: a lower volume flush for liquid waste and a higher volume flush for solid waste. This feature helps conserve water and can lead to cost savings on your water bill. When selecting a dual-flush toilet, consider the following key specifications to ensure you pick the best fit for your needs.
Flush VolumeFlush volume refers to the amount of water used per flush. Dual-flush toilets typically have two flush volumes: a lower volume for liquid waste and a higher volume for solid waste. This spec is important because it directly affects water conservation and efficiency. Lower flush volumes (around 0.8-1.1 gallons per flush) are ideal for liquid waste, while higher volumes (around 1.6 gallons per flush) are used for solid waste. If you are environmentally conscious or live in an area with water restrictions, opting for a toilet with lower flush volumes can be beneficial.
Bowl ShapeThe bowl shape of a toilet can affect comfort and space usage. There are generally two types: elongated and round. Elongated bowls are slightly longer and offer more comfort, making them a popular choice for master bathrooms. Round bowls are more compact and can save space, making them suitable for smaller bathrooms or powder rooms. Consider the size of your bathroom and your personal comfort preferences when choosing the bowl shape.
HeightToilet height can impact ease of use, especially for taller individuals, elderly people, or those with mobility issues. Standard height toilets are typically around 15 inches from the floor to the seat, while comfort height (or chair height) toilets are around 17-19 inches. Comfort height toilets are easier to sit down on and stand up from, making them a good choice for those who need extra accessibility. Consider who will be using the toilet most frequently to determine the best height for your needs.
Trapway DesignThe trapway is the part of the toilet that carries waste from the bowl to the plumbing. A fully glazed trapway can help prevent clogs and ensure a smoother flush. Some toilets also feature a concealed or skirted trapway, which can make cleaning easier and give the toilet a sleeker appearance. If you prioritize ease of maintenance and a modern look, a toilet with a concealed trapway might be the right choice for you.
Material and FinishMost toilets are made from vitreous china, a durable and easy-to-clean material. The finish can vary, with options like standard white, off-white, or even more unique colors. Some finishes also include antimicrobial properties to help reduce bacteria and mold growth. When choosing the material and finish, consider the overall aesthetic of your bathroom and any specific hygiene concerns you may have.
Installation TypeDual-flush toilets can be either one-piece or two-piece designs. One-piece toilets have a seamless design, which can be easier to clean and often looks more modern. Two-piece toilets have a separate tank and bowl, which can be easier to transport and install. Consider your installation preferences and the look you want to achieve in your bathroom when choosing between these types.
