Buying Guide for the Best One Piece Toilets
Choosing the right one-piece toilet involves understanding your needs and preferences, as well as the key specifications that differentiate various models. One-piece toilets are known for their sleek design and ease of cleaning, as the tank and bowl are integrated into a single unit. To make an informed decision, consider the following key specifications and how they align with your requirements.Bowl ShapeThe bowl shape of a toilet can be either round or elongated. Round bowls are more compact and are ideal for smaller bathrooms, while elongated bowls offer more comfort and are better suited for larger spaces. Consider the size of your bathroom and your personal comfort preferences when choosing the bowl shape.
Flushing SystemThe flushing system determines how effectively the toilet clears waste. Common types include gravity-fed, pressure-assisted, and dual-flush systems. Gravity-fed systems are quieter and more common, pressure-assisted systems offer a powerful flush but can be noisier, and dual-flush systems provide options for water conservation. Choose a flushing system based on your preference for noise level, water efficiency, and flushing power.
Water ConsumptionWater consumption is measured in gallons per flush (GPF). Toilets typically range from 1.28 GPF to 1.6 GPF. Lower GPF models are more water-efficient and can help reduce your water bill, while higher GPF models may offer a more powerful flush. Consider your priority between water conservation and flushing performance when selecting the water consumption rate.
HeightToilet height can affect 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 toilets are around 17 to 19 inches. If you have specific comfort needs or accessibility requirements, opt for a comfort height toilet.
Trapway DesignThe trapway is the channel that waste travels through to reach the plumbing. A fully glazed trapway can help prevent clogs and ensure a smoother flush. Some toilets also feature a concealed or skirted trapway for easier cleaning and a more streamlined appearance. If ease of maintenance and aesthetics are important to you, consider these design features.
Material and FinishMost one-piece toilets are made from vitreous china, which is durable and easy to clean. The finish can be standard or include special coatings that resist stains and bacteria. If hygiene and ease of cleaning are top priorities, look for toilets with advanced finishes.
Seat TypeToilets can come with different types of seats, such as standard, soft-close, or heated. Soft-close seats prevent slamming and are quieter, while heated seats offer added comfort. Choose a seat type based on your comfort preferences and the features you value.
