The KOHLER K-20198-7 Betello Two-Piece Toilet offers several notable features that enhance its functionality and comfort. The elongated bowl design provides added room and comfort, which is great for everyday use.

The Revolution 360 swirl flushing combined with the Continuous Clean System ensures efficient and thorough cleaning, helping to reduce maintenance and keep the toilet hygienic with each use.

The skirted base adds to its aesthetic appeal while making it easier to clean around the toilet base.

The two-piece design might be slightly more challenging to clean compared to one-piece models, but it allows for easier installation and repair.

Buying Guide for the Best Kohler 2 Piece Toilets

Choosing the right toilet for your bathroom is an important decision that can impact your daily comfort and the overall functionality of your space. When selecting a Kohler 2-piece toilet, there are several key specifications to consider to ensure you get the best fit for your needs. Understanding these specifications will help you make an informed decision and find a toilet that meets your requirements in terms of performance, efficiency, and design.
Bowl ShapeThe bowl shape of a toilet can be either round or elongated. This specification is important because it affects the comfort and space requirements of the toilet. Round bowls are more compact and are ideal for smaller bathrooms, while elongated bowls offer more comfort due to their extended shape, making them a better choice for larger bathrooms. Consider the size of your bathroom and your personal comfort preferences when choosing the bowl shape.
Flush PerformanceFlush performance refers to how effectively the toilet clears waste with each flush. This is crucial for maintaining hygiene and preventing clogs. Toilets are often rated by their gallons per flush (GPF). Standard toilets use 1.6 GPF, while high-efficiency models use 1.28 GPF or less. If you are looking for water savings and environmental benefits, opt for a high-efficiency model. However, ensure that the toilet still provides strong flushing power to avoid frequent clogs.
HeightToilet height can vary, with standard height being around 15 inches from the floor to the seat, and comfort height (also known as chair height) being around 17-19 inches. This specification is important for accessibility and comfort, especially for taller individuals, the elderly, or those with mobility issues. If you have specific needs or preferences for ease of sitting and standing, consider a comfort height toilet.
Trapway DesignThe trapway is the part of the toilet that carries waste from the bowl to the plumbing. It can be exposed or concealed. Exposed trapways are easier to clean and maintain, while concealed trapways offer a sleeker, more modern look and can be easier to clean around. Your choice will depend on your preference for aesthetics and ease of cleaning.
Material and FinishToilets are typically made from vitreous china, which is durable and easy to clean. The finish can vary, with options like standard white, off-white, or even more unique colors. This specification is important for matching the toilet to your bathroom decor and ensuring long-term durability. Choose a material and finish that complements your bathroom style and is easy to maintain.
Seat TypeToilet seats can come in various types, including standard, soft-close, and heated. This specification affects the comfort and convenience of the toilet. Soft-close seats prevent slamming and are quieter, while heated seats add extra comfort, especially in colder climates. Consider your comfort preferences and any additional features you might find beneficial when selecting the seat type.
