Our take on the KOHLER K-3814 Corbelle Two-piece elongated toilet with skirted trapway, 1.28 gpf

The Kohler Corbelle is a two-piece elongated toilet with a skirted trapway that hides the waste channel and makes the outside easier to wipe down. Revolution 360 swirls water around the bowl to keep it cleaner between scrubs, and the 1.28 gpf flush meets WaterSense efficiency. Comfort Height seating puts the rim at chair height, which helps adults with knees or mobility issues. Against basic builder-grade toilets it adds the skirted look, the ReadyLock floor mount and a glazed 2-1/8-inch trapway; against one-piece skirted models it trades a visible seam for easier handling and a lower weight.

What reviewers say

Owners of skirted Kohler two-piece toilets generally praise the clean look and the strong swirl flush, and Comfort Height is a common reason people pick it. Complaints tend to center on the tank-to-bowl seam and on the cost of model-specific parts.

What people mention

  • CleaningPraisedThe smooth skirted sides and CleanCoat glaze are called easy to wipe and slow to stain.
  • Seat heightPraisedComfort Height is a frequent reason buyers choose it, especially for older adults.

About the KOHLER K-3814 Corbelle Two-piece elongated toilet with skirted trapway, 1.28 gpf

The KOHLER Corbelle K-3814 is a two-piece, elongated toilet with a skirted trapway and a 1.28 gpf (4.8 lpf) flush. Its Revolution 360 flushing technology creates a forceful swirling motion that keeps the bowl clean longer than a conventional flush. The skirted trapway simplifies cleaning, and the CleanCoat surface treatment inhibits the growth of water scale and mineral stains.

The AquaPiston canister uses gravity and the natural cascade of water to increase the power of the flush. It takes less force to actuate than a 3" (76 mm) flapper and has 90% less exposed seal material, which resists wear, shrinkage and swelling. The trip lever is on the left-hand side.

The patented ReadyLock system attaches the skirted trapway to the floor flange and the toilet, so no holes need to be drilled in the floor. The Comfort Height feature gives chair-height seating that makes sitting down and standing up easier for most adults. The toilet is WaterSense labeled and may be eligible for consumer rebates in some municipalities.

Questions and answers

What is the difference between the Corbelle and the Corbelle with ContinuousClean?
The K-3814 is the standard Corbelle. The K-5709 adds Kohler's ContinuousClean system, which dispenses cleaning tablets into the bowl with each flush.
Does it fit a standard 12-inch rough-in?
Yes. The ReadyLock system is designed for a standard 12-inch rough-in and mounts to the floor flange without drilling holes.
How much water does it use?
It flushes at 1.28 gallons per flush and carries the WaterSense label, so it uses less water than older 1.6 gpf toilets.
What is included in the box?
The combination is the K-4144 bowl and K-4143 tank. A seat and supply line are not part of the toilet itself, so check the listing for what the seller bundles.
Is the bowl elongated or round?
It is an elongated bowl, which gives more room front to back than a round front.
Does the skirted base make clogs harder to fix?
It can. The skirt hides the trapway, so a stubborn clog may need a flange-level auger rather than easy access from the side.
