10 Best Kohler High Toilets 2025 in the United States

The Kohler K-5401-PA-0 Veil Comfort Height toilet is designed to offer modern convenience and comfort. Its comfort height and elongated bowl make it easier for adults to use, aligning well with the category's needs for a high toilet. The dual-flush technology is a standout feature, allowing users to choose between a full or partial flush, which can help save water. Additionally, the tankless design contributes to a sleek, minimalist appearance, though it may require adaptation for some plumbing systems.

This model is packed with high-tech features such as a heated seat with adjustable temperatures, motion-activated and hands-free cover opening, and a touch-screen LCD remote for easy operation. These functionalities enhance user comfort and convenience, making it appealing for those who appreciate smart home technology.

Ease of cleaning is addressed through a self-cleaning function that uses UV light and electrolyzed water to maintain hygiene. This, along with the automatic deodorization system, could reduce maintenance time. However, the reliance on such advanced systems might require additional upkeep and understanding from the user. Installation should be straightforward with standard floor-mount requirements, though it does require a power source for its electronic features, which might not be available in all bathrooms.

The toilet's design and features suggest a higher price point, which might not be for everyone. It weighs 86 pounds and is constructed from porcelain, ensuring durability but could be cumbersome for some installers. The Kohler K-5401-PA-0 is a technologically advanced toilet best suited for those who prioritize comfort, ease of use, and are willing to invest in a premium product. Its combination of modern features and user-friendly design makes it a compelling choice, albeit potential buyers should consider the need for electrical installation and higher maintenance for its complex features.

The Kohler K-3999-U-0 Highline Comfort Height Toilet is designed with comfort and functionality in mind, especially for adults who find standard toilets too low. Its ‘Comfort Height’ feature raises the seat to about chair height, making sitting down and standing up easier, which is great if you have mobility concerns. The toilet has an elongated bowl, offering more space and a bit more comfort compared to round bowls. It uses a gravity flush system combined with Kohler’s Class Five flushing technology, which is known for strong flushing power and reliable performance, helping to keep the bowl clean and reducing clogs.

Water efficiency is decent at 1.28 gallons per flush, meeting WaterSense certification, so it balances effective flushing with water conservation. The two-piece design with a separate tank and bowl is standard and allows easier handling during installation or repairs. Installation is floor-mounted with a standard 12-inch rough-in, fitting most typical bathroom setups. The included polished chrome trip lever is positioned for left-hand use, which may be a consideration if you prefer right-hand operation.

One downside might be the weight—at 100 pounds, it’s relatively heavy, so installation might require two people. Also, while the insuliner tank liner helps prevent condensation in humid environments, the ceramic china material requires regular cleaning to maintain its look and hygiene like most toilets. It is suitable for those wanting a comfortable, slightly taller toilet that performs well and saves water, ideal for most adult users but may need professional help during installation.

The KOHLER K-6669-95 Memoirs Stately Comfort Height Elongated Toilet offers several appealing features for users seeking a comfortable and efficient toilet. With its Comfort Height design, this model is ideal for individuals who prefer a chair-height seating position, making it easier for most adults to sit down and stand up. This is especially beneficial for taller individuals or those with mobility challenges.

The elongated bowl shape enhances comfort, while the concealed trap way not only contributes to a sleek, modern design but also makes cleaning simpler, reducing the time and effort involved in maintaining hygiene. The Aqua Piston flush technology is a standout feature, as it allows water to flow into the bowl from all sides, ensuring a powerful and effective flush with a water consumption rate of 1.28 gallons per flush. This efficient water usage can lead to some savings on water bills over time.

However, there are a few considerations to keep in mind. The toilet's weight of over 110 pounds might make installation slightly challenging for some, and professional help could be needed. Additionally, while the toilet includes a left-hand polished chrome trip lever, it does not come with a seat or supply line, which means additional purchases are necessary before full use. The ice gray color offers a unique aesthetic but may not be to everyone's preference, particularly if they are looking for a more traditional white finish. Given its high rank among two-piece toilets and a decent customer review score of 3.8 out of 5, it indicates that most users are satisfied with its performance, though there might be some room for improvement in specific areas.
