10 Best Kohler Toilets 2026 in the United States

The KOHLER 3940-96 Kathryn Comfort Height Elongated Toilet is designed for those who prefer a stylish and functional bathroom fixture. Its one-piece construction offers a seamless look that's easy to clean, making it ideal for busy households. The Comfort Height feature is particularly beneficial for older adults or anyone who may struggle with lower toilet heights, providing added convenience. With a water consumption rate of 1.28 gallons per flush, it is WaterSense certified, promoting water efficiency without sacrificing performance.

One of the standout aspects of this model is the AquaPiston flush technology, which allows water to flow into the bowl from all sides, resulting in a powerful and effective flush. This is complemented by a durable canister design that reduces the risk of leaks compared to traditional flapper systems.

There are some considerations to keep in mind. Weighing in at 105 pounds, installation may require assistance due to its considerable weight. Additionally, while it's classified as a one-piece toilet, its size may not suit every bathroom layout, especially smaller spaces. The color, Biscuit, might limit compatibility with other design choices in your bathroom. This KOHLER toilet is a solid choice for those looking for a comfortable, efficient, and stylish option, though careful consideration of your bathroom's space and color scheme is recommended.

The KOHLER K-5172-96 San Souci Comfort Height Toilet stands out in several key areas. Its elongated bowl design offers additional comfort while occupying the same amount of space as a traditional round bowl, making it suitable for bathrooms with limited space. The Comfort Height feature, which corresponds to chair-height seating, is particularly beneficial for adults and the elderly as it makes sitting down and standing up easier.

One notable feature is the AquaPiston flushing technology. This ensures powerful and effective flushing by allowing water to flow into the bowl from all sides. Another advantage is the durable canister design that has fewer exposed seal materials compared to a traditional flapper, reducing the chance of leaks. The compact one-piece design is sleek and modern, making it a good fit for those interested in a stylish bathroom fixture.

Additionally, the water consumption is rated at 1.28 gallons per flush, making it an eco-friendly choice that meets the WaterSense certification standards. However, there are some considerations to keep in mind. The toilet is relatively heavy at 94 pounds, which might make installation a bit challenging. Also, it has a single left-hand trip lever, which might not be ideal for everyone. Lastly, it is positioned at a higher price point, which may not suit all budgets. The KOHLER K-5172-96 is a strong candidate for those wanting a high-efficiency, stylish, and comfortable toilet but should be mindful of the installation challenges and price.

The Kohler 30811-96 Santa Rosa is a one-piece toilet that combines the tank and bowl into a smooth, easy-to-clean unit. Its compact elongated bowl offers more comfort than a standard round shape but fits in the same space, making it a good choice for smaller bathrooms. The Comfort Height design means the seat is a bit taller, which many adults find easier for sitting and standing.

It uses 1.6 gallons of water per flush, which is a common, water-efficient level, and the Revolution 360 flushing technology creates a strong swirling action to keep the bowl cleaner for longer. The CleanCoat surface helps prevent mineral stains and scale build-up, reducing cleaning effort. The biscuit color and Santa Rosa style provide a classic, neutral look that fits various bathroom decors.

The toilet is praised for comfort and effective flushing but is a bit heavy at over 90 pounds, making installation more challenging for some. The left-hand trip lever is a standard feature but may not suit all bathroom layouts. This toilet is well-suited for those wanting a stylish, comfortable one-piece model with reliable flushing and easy cleaning, especially in compact spaces.
