Review of the Kohler Highline Toilet (Updated)

“The Highline is high-class. The sleek model is both aesthetically pleasing and long-lasting.”

This toilet is one of Kohler’s greatest hits.

Flushing Performance

The Highline uses Kohler’s Class Five flushing technology to reduce the likelihood of clogs. The single-flush gravity system utilizes gravitational force for an extra-strong flushing siphon. Kohler optimizes siphon strength through its specially engineered tank, bowl, and trapway.

The Highline uses 1.28 gallons per flush, saving you about 20 percent on your annual water bill, when compared to traditional 1.6gpf models. The toilet is EPA WaterSense-certified and is eligible for consumer rebates in some municipalities.

Design

This vitreous china two-piece toilet looks and feels good from the get-go. At first glance, you’ll notice the angular structure of the tank, which gives the model a fresh look. The toilet comes in white, biscuit, and black black.

The extra-comfortable elongated bowl helps disperse user body weight , elevating user experience. The Highline is a Comfort Height toilet, with a seat height of 16.5”.  The toilet comes with a tank, tank cover, bowl, trip lever, and bolt cap accessory pack. A supply line and wax ring are not included but are needed for installation.

One of the best parts of this toilet is its easy installation process. Thanks to the three-bolt quick-connect installation, you won’t need professional help! Simply install the floor-mount/floor outlet toilet according to Kohler’s beginner-friendly instructions.

Comparisons – Kohler Highline vs. Wellworth

This unit is on the lower end of Kohler’s line of toilets. While it’s not their most basic model, it certainly lacks some of the luxury features that the pricier designs have incorporated.

However, Kohler has engineered the Highline to still perform at a high level, even though it does so with more basic technologies. For instance, rather than Kohler’s Revolution 360Ⓡ flush system, it uses a more basic Class FiveⓇ flush valve. This toilet also lacks the self-cleaning features and antimicrobial surface coatings that Kohler has made standard on their other models.

Let’s compare the Highline to Kohler’s most basic model, the Wellworth, to see how the two stack up.
