Kohler Devonshire toilet review: What drawbacks did we find?

Last updated: October 20, 2026

The Kohler Devonshire toilet is a high-efficiency and comfortable toilet with an elegant, traditional design. This toilet has impressed me with its combination of water-saving performance, comfortable seating, and attractive appearance. Compared with the Kohler Persuade and Kohler Corbelle, the Devonshire stands out for its classic styling.

The manufacturer offers several finishes to complement different bathroom colors, including White, Biscuit, Almond, Black Black, Ice Grey, and Sandbar. However, color availability may vary depending on the model and retailer.

The Kohler K-3837-96 Devonshire is a two-piece toilet with a Comfort Height design and an elongated bowl. Its chair-height seating makes sitting down and standing up easier for many adults.

It also features Kohler’s AquaPiston canister flush valve, which releases water into the bowl from all sides to create an effective gravity-powered flush. The toilet uses only 1.28 gallons per flush (GPF), helping reduce household water consumption without sacrificing everyday flushing performance.

Note: The Kohler Devonshire K-3488-0 is a different model. It features a one-piece design, uses 1.6 GPF, and includes a Glenbury Quiet-Close toilet seat. This review focuses on the two-piece K-3837 model.

These and several other features are discussed below in our Kohler Devonshire toilet review. Continue reading to understand its flushing technology, comfort, installation requirements, pros, and cons.

Comfort Height Kohler Devonshire Toilet Review in 2026

Vitreous China Construction

If you have used Kohler toilets before, you probably know that the company focuses on durable construction. The Devonshire elongated toilet is no exception. It is made from vitreous china, a durable ceramic material with a smooth glazed finish.

The glazing helps resist stains and makes regular cleaning easier. With proper installation and maintenance, this toilet can provide many years of reliable service.

It also features a sturdy trip lever that operates the flushing mechanism. The lever is conveniently positioned on the left side of the tank.

Excellent Design and Finish

Whether you have a modern or traditional bathroom, the Kohler Devonshire toilet can look beautiful in it. The toilet features elegant curves and decorative details inspired by classic bathroom fixtures.

The Biscuit finish is particularly attractive for bathrooms with warm or neutral colors. You can also select other available finishes to match your bathroom fixtures.

Unlike plain contemporary toilets, the Devonshire has a more decorative exterior. While this gives it a distinctive appearance, the extra curves may require additional attention during cleaning.

1.28 GPF Water-Efficient Toilet

The Kohler Devonshire uses only 1.28 gallons of water per flush. According to Kohler, it can save up to approximately 16,500 gallons of water annually compared with an older 3.5 GPF toilet, based on the manufacturer’s usage assumptions.

Actual water savings depend on how frequently the toilet is used and the water consumption of the model being replaced.

The K-3837 also carries the EPA WaterSense label, meaning it meets established water-efficiency and flushing-performance requirements.

Another advantage is that some municipalities and water utilities offer rebates for eligible WaterSense toilets. However, the availability and amount of these rebates depend on your location.

If reducing water consumption is important, you can also explore other high-efficiency toilet options before making a final decision.

Comfort Height Elongated Bowl Design

Another feature that sets the Devonshire apart from many standard-height toilets is its comfort.

The bowl stands approximately 16.5 inches high without the toilet seat. With a compatible seat installed, the total seating height is generally around chair height, although the exact measurement depends on the seat.

This design makes sitting down and standing up easier for many adults, particularly taller users and people who have difficulty using lower toilets.

The elongated bowl also provides more seating space than a typical round-front design. However, because elongated toilets extend farther forward, you should check your bathroom dimensions before purchasing.

The Devonshire K-3837 can satisfy applicable ADA accessibility requirements when installed according to the relevant standards. The bowl height alone does not guarantee that every installation is ADA-compliant.

12-Inch Rough-in

Installing the Kohler Devonshire is relatively straightforward when your bathroom has a standard 12-inch rough-in.

The rough-in is the distance from the finished wall behind the toilet to the center of the floor drain or closet flange. Always measure from the finished wall, not the baseboard.

Since the Devonshire is a two-piece toilet, you can position the bowl first and then attach the tank. This can make handling the toilet easier than moving a heavy one-piece model.

It also features Kohler’s three-bolt quick-connect installation system, which helps simplify tank attachment.

However, the toilet seat and supply line are sold separately. You should also confirm whether the wax ring and installation hardware are included in the package you purchase.

Kohler AquaPiston Canister Flush Valve

One of the best features of the Kohler Devonshire toilet is its AquaPiston canister flushing system.

Unlike a traditional flapper system, the AquaPiston canister allows water to enter the bowl from multiple directions. This creates a strong flow that helps remove waste efficiently.

The canister also uses less exposed seal material than a conventional 3-inch flapper, helping reduce certain types of seal wear.

Its light-touch design requires relatively little force to operate the flush lever.

However, no toilet is completely clog-proof. Excessive toilet paper, non-flushable wipes, or existing drain problems can still cause blockages.

Powerful Gravity Flushing System

The Kohler Devonshire K-3837 uses a gravity-assisted flushing system with AquaPiston technology.

The combination of the canister valve, engineered bowl, and fully glazed trapway helps create a strong siphonic action during flushing.

This system is designed to remove bulk waste effectively while using only 1.28 gallons of water.

Although some other Kohler toilets use Class Five flushing technology, the Devonshire K-3837 is specified with AquaPiston canister flushing, so the two technologies should not be confused.

Manufacturer’s Limited Warranty

Kohler provides limited warranty coverage for its toilets. The exact coverage depends on the product, components, purchase conditions, and current warranty terms.

Before ordering, review the warranty provided with the specific Devonshire model. Keep your purchase receipt in case you need replacement parts or warranty assistance later.

Kohler Devonshire vs. Kohler Memoirs Toilet Comparison

Both the Kohler Devonshire and Kohler Memoirs toilets offer traditional styling and comfortable seating. However, their appearance and specifications differ depending on the exact model.

The following comparison uses the Devonshire K-3837 and the Memoirs Stately K-3817 as examples.

If saving water is your priority, the Devonshire K-3837 has an advantage over the 1.6 GPF Memoirs K-3817. However, Kohler also offers other Memoirs configurations with lower water consumption, so compare exact model numbers before making a decision.

Summary

If you want a powerful and attractive toilet for your bathroom, the Kohler Devonshire two-piece toilet is worth considering.

It combines an elegant traditional appearance with practical modern features, including AquaPiston flushing, Comfort Height seating, an elongated bowl, and water-saving performance.

The toilet is also relatively easy to install when your bathroom has a compatible 12-inch rough-in. Its durable vitreous china construction makes it suitable for everyday household use.

However, keep in mind that the toilet seat and supply line are sold separately. The decorative exterior may also require more cleaning than a smooth, skirted toilet.

Overall, this Kohler Devonshire toilet review shows why the K-3837 remains a good choice for homeowners who prefer traditional styling without giving up water efficiency.
