Buying Guide for the Best Toilets 18 Inches High
Choosing the right toilet for your bathroom is essential for comfort, functionality, and style. When selecting a toilet, it's important to consider various specifications to ensure it meets your needs and preferences. Here are some key specs to consider when picking a toilet, especially one that is 18 inches high.HeightToilet height is crucial for comfort and accessibility. Standard toilets are typically around 15 inches from the floor to the seat, while comfort height toilets are around 17 to 19 inches. An 18-inch high toilet falls into the comfort height category, making it easier for people with mobility issues, the elderly, or taller individuals to sit down and stand up. If you or someone in your household has difficulty using standard height toilets, an 18-inch high toilet can provide added comfort and ease of use.
Bowl ShapeToilet bowls come in two main shapes: round and elongated. Round bowls are more compact and can save space in smaller bathrooms, while elongated bowls offer more comfort due to their larger seating area. If space is limited, a round bowl might be the better choice. However, if comfort is a priority and you have enough space, an elongated bowl can provide a more pleasant experience.
Flushing SystemThe flushing system determines how effectively the toilet clears waste. There are several types, including gravity-fed, pressure-assisted, and dual-flush systems. Gravity-fed systems are common and reliable, using the force of gravity to flush. Pressure-assisted systems use air pressure to enhance flushing power, which can be beneficial for larger households or commercial use. Dual-flush systems offer two flush options (a full flush for solid waste and a half flush for liquid waste), which can save water. Consider your household's needs and water usage habits when choosing a flushing system.
Water EfficiencyWater efficiency is important for both environmental and cost-saving reasons. Toilets are rated by their gallons per flush (GPF). Older models may use up to 3.5 GPF, while modern toilets typically use 1.6 GPF or less. High-efficiency toilets (HET) use 1.28 GPF or less, and some ultra-high-efficiency models use as little as 0.8 GPF. If conserving water is a priority for you, look for a toilet with a lower GPF rating. This can also help reduce your water bill over time.
Installation TypeToilets can be either one-piece or two-piece. One-piece toilets have a seamless design, making them easier to clean and often more aesthetically pleasing. Two-piece toilets have a separate tank and bowl, which can be easier to transport and install. If you prefer a sleek, modern look and easier maintenance, a one-piece toilet might be the best choice. If you are looking for a more traditional style or easier installation, a two-piece toilet could be more suitable.
Additional FeaturesModern toilets can come with a variety of additional features, such as bidet functionality, heated seats, night lights, and self-cleaning systems. These features can enhance comfort and convenience but may also increase the cost. Consider which features are important to you and your household. For example, a bidet function can improve hygiene, while a heated seat can add comfort during colder months. Prioritize the features that will provide the most benefit to your daily routine.
