Buying Guide for the Best Kohler One Piece Toilets

Choosing the right one-piece toilet can significantly enhance the comfort and functionality of your bathroom. One-piece toilets are known for their sleek design, ease of cleaning, and often more modern look compared to two-piece toilets. When selecting a one-piece toilet, it's important to consider several key specifications to ensure you get the best fit for your needs and preferences.
Bowl ShapeThe bowl shape of a toilet can affect both comfort and space utilization. There are generally two types: elongated and round. Elongated bowls are more comfortable for most adults due to their oval shape, but they take up more space. Round bowls are more compact, making them ideal for smaller bathrooms. Choose an elongated bowl if comfort is your priority and you have enough space. Opt for a round bowl if you need to save space or have a smaller bathroom.
Flush PerformanceFlush performance determines how effectively the toilet clears waste. This is often measured in terms of gallons per flush (GPF). Modern toilets typically use 1.28 GPF or 1.6 GPF. A lower GPF is more water-efficient and environmentally friendly, but you want to ensure it still provides a powerful flush. If you are environmentally conscious or live in an area with water restrictions, a 1.28 GPF toilet is a good choice. If you prioritize a strong flush and don't have water usage concerns, a 1.6 GPF toilet might be better.
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 about 17-19 inches. Comfort height toilets are easier to sit down on and stand up from, making them a good choice for older adults or anyone with knee or back problems. Standard height toilets might be preferable for shorter individuals or children.
Material and FinishThe material and finish of a toilet affect its durability and ease of cleaning. Most toilets are made from vitreous china, which is durable and has a smooth, glossy finish that resists stains and is easy to clean. Some toilets come with additional coatings that further enhance cleanliness by preventing bacteria and mold growth. If you want a low-maintenance toilet, look for one with an advanced finish or coating. For general use, vitreous china is a reliable and common choice.
Noise LevelThe noise level of a toilet can be an important consideration, especially if the bathroom is near living areas or bedrooms. Some toilets are designed with quieter flush mechanisms to minimize noise. If you are sensitive to noise or have a bathroom close to sleeping areas, look for a toilet that is specifically marketed as having a quiet flush. For bathrooms that are more isolated, noise level might be less of a concern.
Ease of InstallationEase of installation can save you time and money, especially if you plan to install the toilet yourself. One-piece toilets are generally heavier and more cumbersome to install than two-piece models, but they often come with straightforward installation instructions. If you are a DIY enthusiast, look for a toilet with clear instructions and all necessary hardware included. If you prefer professional installation, consider the additional cost and complexity.
