Kohler Highline Classic Features

While the Kohler Highline Classic is not one of those fancy toilets that come with advanced functions, it still offers all the important features. Let’s take a closer look at the key features.

Comfort Height

Being two inches higher than standard toilets, the Kohler Highline Classic offers comfortable seating at the chair level. This makes it easier to sit down and stand up.

Seniors and adults with knee or lower back problems will appreciate the slightly raised height. On the other hand, the toilet can be a little tall for small children.

High-Quality Materials

The porcelain materials contribute to the great durability in addition to the elegant look. Vitreous china has been proven to be an extremely durable material, so this toilet is built to last a lifetime.

What’s more, it is very resistant to dust and dirt. It will save you the hassle of cleaning your toilet frequently and leave you more time for other things.

Structure & Design

This is a two-piece toilet – the bowl and tank are separated – that comes with an elongated seat for added comfort.

So, let’s check these components separately.

  • Bowl: The ceramic bowl features an elongated floor mount base for the added room. Take it into consideration if you have a small bathroom. Also, the bowl is somewhat longer than usual. That’s why the total toilet length (from the outer edge to the back wall) is slightly increased.
  • Tank: The uniquely shaped tank is equipped with a sturdy punch or plunger for improved functionality. It leverages a pressure-assisted flush action to remove any clogs in the flush valve. Note that the flush trip lever is located on the left side.

Overall, this well-designed unit looks nice and fits in with various bathroom decors. It blends in perfectly with most bath styles and fixtures, so it will very likely be a good match for your bathroom.

Powerful Flushing System

Pressure Lite trademark technology is certainly the best feature of this gravity-flush toilet. Thanks to this powerful system, the toilet can do a terrific job of flushing the waste. At the same time, it will reduce your water footprint using only 1.6 gallons per flush.

How to Install the Kohler Highline Classic Toilet

  • Vague instructions: Most instructions are pretty clear. The section that describes how to attach the bowl to the tank is not explained clearly, though.
  • Gasket bolts aren’t long enough: You will have a difficult time connecting the tank with the toilet bowl. That’s because of the short gasket bolts that are not capable of extending through the mounting holes. These bolts should be forced back in the tank manually.
  • You won’t get all the necessary hardware: Despite being a factory-sealed box, the toilet may lack some components. The company refuses to ship replacement hardware in most cases.
