We at Toiletable are experts when it comes to all things toilets – so trust us when we say the Corbelle is worth the look. This two-piece unit features some of Kohler’s best features, such as its flushing and glaze technology.
Flushing
In its precision-engineered tank, bowl, and trapway, the Corbelle harnesses the power of gravity to create an extra-strong siphon during flushing thanks to Revolution 360 flushing technology.
The high-quality AquaPiston canister further increases efficiency by letting water flow in through every side of the bowl.
This toilet’s light-touch canister requires a lower actuation force than a flapper. The canister’s design has 90% less exposed seal material than traditional three-inch flapper, reducing chance of leakage.
The toilet’s flush valve also has a 3:2 ratio that further optimizes flush performance through the power of gravity.
At 1.28 gallons per flush, this unit saves you thousands of gallons a year, when compared to traditional 1.6gpf units. Qualifying for EPA WaterSense, this model helps the environment while cutting your water bills each month. The Corbelle’s trapway is a bit over two inches, increasing water flow for easy waste removal.
Smart Design
We’ve been reviewing Kohler toilets for years and each time we see a toilet with this feature we get excited. The Corbelle has Kohler premium CleanCoat surface treatment which inhibits the growth of water scale and mineral stains. This helps cut down on cleaning by preventing potential stains from lingering.
You can even upgrade this feature through the K-5709 Corbelle model which comes with the ContinousClean XT system, an automated cleaning solution dispenser that cleans your bowl with every flush.
The Corbelle’s skirted trapway also simplifies cleaning as it eliminates any nooks and crannies that dirt and grime gravitate towards.
The Corbelle is ADA-compliant, with its 16.5” bowl height and elongated bowl shape. The chair-like height makes sitting and standing up hassle-free while the bowl shape helps disperse user body weight for a more comfortable experience.
The toilet is available in white, biscuit, dune, ice grey, and black black; it comes with a left-hand polished chrome trip lever. A seat and supply line must be purchased separately. The toilet is compatible with the Kohler Quiet-Close elongated toilet seat and elongated bidet toilet seat with remote control.
The toilet has a standard 12” rough-in but we noticed that a 10” rough-in kit is also available, making the Corbelle a fantastic fit even for small bathrooms.
A 14” rough-in kit is available as well.
Our experience with this Kohler collection is that installation is very simple.
The Corbelle uses the patented ReadyLock installation system which saves time and stress by eliminating the need for drilling. The unit can be floor-mounted without professional help.
Overall the Corbelle is an affordable model that we love. But don’t just take it from us.
Check out the toilet’s Amazon reviews and you’ll see how much others enjoy the toilet’s easy maintenance and powerful flushing system.
The most common positive features that are mentioned about the Corbelle are the toilet’s reliable flushing performance and manageable upkeep. Users note that the toilet is affordable yet in no way sacrifices in quality.
The glaze holds up over long periods of time and the flushing mechanism doesn’t lose power. The most common complaint is that the toilet does not come with a seat, resulting in yet another additional purchase.
