The Kohler Corbelle Toilet Review (Two-Piece) 1.28 GPF – Toiletable

If there’s one household item that should be an optimal blend of style, utility, cleanliness, and comfort, it’s your toilet. Today, we’re taking a look at a toilet that should fit the bill: the Kohler Corbelle.

Kohler is well known for designing and manufacturing top-of-the-line sinks, toilets, bathtubs, and showers, as well as other household appliances.

The unit we’re examining today, the Corbelle, lies in the middle ground of Kohler’s extensive range of toilets. While not as technology heavy as their luxury lines, the Corbelle has more features and a more elegant design than Kohler’s budget model.

Keep reading as we take a deeper dive into the Corbelle’s specific features and standout details.

 Kohler Corbelle – Specifications

The Corbelle is a two-piece toilet, meaning the bowl and tank are separate pieces that need to be fitted together during installation. Some retailers may even sell the bowl and tank separately. If purchased from Kohler, the unit comes in six different colors of vitreous china, ranging from white to black, all of which are treated with Kohler’s patented CleanCoat to help keep your toilet surface extra clean.

This toilet was designed with both comfort and efficiency in mind. It has a sleek profile that is both pleasing to the eye and was specifically engineered for easy cleaning. And when it comes to performance, the mechanical components are powerful enough to swiftly evacuate waste with a single flush.

 Kohler Corbelle – Features and Highlights

The Corbelle has a number of notable features. Let’s examine a few of them in detail.

1. Skirted Trapway

A toilet’s trapway is the channel that waste flows through as it leaves the bowl; in traditional toilets the trapway is exposed, resulting in a tube extending from the bottom of the bowl to the floor. This swirling design is both unsightly and difficult to clean, due to its many curves and hard-to-reach angles. However, the Corbelle features a modern design element known as a skirted trapway, meaning the trapway is covered by a smooth plate of china, hiding away all of the tubings under the surface. This flat skirt can be easily cleaned with one swipe and keeps your bathroom looking neat and tidy.

2. Comfort HeightⓇ Seat

A traditional toilet seat can be as low as 12” inches off the ground. While this height is fine for shorter adults and children, many have found that they prefer a “comfort height” toilet like that offered by the Corbelle. Kohler designed this model with a seat height of 16.5” inches, which is an optimal level for comfort without making the seat too high or difficult to climb onto. Those with a history of knee and joint problems, arthritis, balance problems, or back pain may especially benefit from a comfort height toilet like the Corbelle.

3. Revolution 360Ⓡ Flush

Featured in the Corbelle, Kohler’s patented Revolution 360Ⓡ flush uses gravity and a specifically engineered bowl, trapway, and tank to create a system that can clear any waste with a single flush of only 1.28 gallons of water.

To achieve this strong flush, basically, the Aqua PistonⓇ canister system optimizes the initial surge of kinetic energy that comes from gravity pulling water from the tank into the bowl. This canister is also far less likely to leak compared to a normal 3” flapper. The water then drains directly out of the toilet’s bowl, resulting in a flush that is far quieter than a normal toilet but still just as efficient.

4. CleanCoatⓇ

As mentioned above, no matter what color of china you choose for your Corbelle, it will be treated with Kohler’s CleanCoat solution. You can rest easy knowing that Kohler’s proprietary technology of specialized nano and repellent particles will keep your toilet free from scaling, water rings, and calcifications. The CleanCoat surface will also help keep the toilet clean from germs and waste for longer than a typical toilet.

One detail to note about this surface is that Kohler does recommend that you never clean it with any abrasive brushes or harsh chemicals, including bleach. Using a strong cleaner can actually strip the CleanCoat off of your toilet, so they recommend a gentle cleanser to ensure the toilet’s surface stays in top condition.

5. Continuous Clean

While Continuous Clean is an optional feature, it still deserves a special mention here. If you choose to add it on, the Corbelle comes with Kohler’s Continuous Clean system, which works with the Revolution 360 flush and CleanCoat to give you a sparkling toilet bowl with almost zero effort. With Continuous Clean, all you do is drop a single white toilet tank cleaning tablet into a compartment in the upper toilet tank, and the Corbelle will mix the dissolved cleaning solution into the flush water, dispensing the perfect amount of cleaning power every time. Kohler reports that this system works with any type of solid white toilet cleaning tablets and that a single tablet can last up to a year! There’s even an indicator light that reminds you to drop a new tablet in when it’s time. With this additional feature, you can replace your typical bathroom cleaning maintenance with this simple-to-use system.

Simple Installation

The Corbelle features a relatively simple installation. To start, the bowl and trapway are formatted with Kohler’s EasyLock™ installation hardware. After installing the plastic trapway, the skirt and bowl fit directly over it, with no need to drill into the floor. That being said, some customer reviews do report that even with the EasyLock™ system, installing this toilet was tough for their plumber. Before purchasing, it may be a good idea to see if your local plumber is familiar with EasyLock™, or find one who is.

In general, the Corbelle is optimized for installation with a 12” rough-in, which is standard for the majority of residential and commercial plumbing. However, if your bathroom doesn’t have a 12” rough-in, Kohler does also sell kits to convert the toilet for installation with a 10” or another size rough in instead. Additionally, thanks to the two-piece construction of the toilet, transporting it into the bathroom will be easier for you or your plumber.

Warranty

Kohler is known for its durable toilets and appliances, but if something does go wrong with your Corbelle, you can rest easy knowing it’s covered under a limited warranty. See below for what is covered for a residential installation:

• Mechanical Components – 10 Year
• Mechanical Components (with Continuous Clean) – 1 Year
• Vitreous China Material – Lifetime

Like with most units, the warranty does vary slightly for commercial installation and is not valid in cases of improper care and cleaning, or anything that may occur during installation or removal of the unit.
