Let’s take a closer look at the Kohler Highline toilet specs and features that will help decide on this model.

Design

This model is made of white Vitreous China, which is durable and resistant to microbes. The general form is standard which means classic, so it’ll fit any interior of the bathroom.

Material

Glass porcelain is a special enamel coating that is applied to ceramics after firing. The result is a white, smooth, and clean product. Similar material is used in this toilet, so it is quite durable and practical in everyday care.

Shape and dimensions

The dimensions of the model are 29 to 1/2 inches (74.9 centimeters) x 18 (45.7 centimeters) x 31 to 1/4 (79.4 centimeters). This toilet has a higher fit than other models. It is more comfortable for adults who are not used to sitting too low.

Please note that this is an elongated version for a more comfortable fit.

Flushing technology

You will definitely love this model’s dual flush. It is convenient to use a large lever for flushing, which is located on the flush tank. Press it twice to make a powerful double flush.

The toilet is equipped with a very powerful flush valve that brings a large amount of water as soon as you press the pedal on the side. This means you’ll be able to remove any blockages without difficulty.

The flush tank has a capacity of 1.28 gallons, which is about 20% less than the 1.6-gallon models. It is due to the international EPA standard requirements, helping you save more water in daily use.

Extra features

This model has some additional features that may take time for you to notice:

  • The height and length correspond to the size of an ordinary chair, which makes the landing more comfortable and familiar;
  • The highest flush performance class eliminates clogging the toilet;
  • Easy three-bolt fastening without the need for complicated tools;
  • Watersense certification is available.

Many customers compare Kohler Highline vs. Cimarron, as they both have the same price range. Two well-known brands in the world of sanitary ware produce quality products, but their models and positioning differ from each other.

The Kohler Highline toilet bowl has a unique concept. This toilet is designed for economical water consumption with powerful flushing. And the case is of a slightly increased size. Most often, the Kohler Highline is purchased by middle-aged and older people.

Price range and warranty

American brand of sanitary ware Kohler produces products of the middle and high price segments. This model of toilet costs up to $300, depending on the configuration. Please note that the kit does not include a sitter, which you can buy separately. For this price, you get a drain cistern, a flush button, and a pedestal, as well as fasteners for mounting the toilet.

The products are covered by the manufacturer’s warranty for 12 months. If a mechanical crack is formed through your fault on the porcelain case, the manufacturer is unlikely to recognize this as a warranty case. However, Kohler Highline toilet problems are very rare. This sanitary ware is of very high quality.

Installation

This Kohler elongated toilet has 12 inches rough-in diameter. Despite such a large size, this model is in line with EPA international standards, as it consumes 20% less water.

9.5Expert Score

Installation of this toilet is very simple. The set includes three anchor bolts with white plugs in the color of the headboard body. The fixing holes’ location is standard, so you do not have to drill new mounting holes. Simply place the case where required and tighten the bolts to ensure good stability.

    it’s more than comfort height: it’s the easiest one to use for a tall heavyweight person like me, though none of my family complains. Though some say Kohler ones are subject to clogging, I never experienced it with mine, even with partial flush. design is elegant and easy to approach. yYou feel comfortable on it. It was easy to install, though you won’t think of it often.
