Why Homeowners Choose the KOHLER Cimarron
For homeowners throughout Northern Virginia and Maryland looking for a dependable premium toilet without moving into the highest-priced luxury category, the Cimarron offers an appealing combination of proven flushing technology, comfort, simple maintenance and classic KOHLER styling.
Dependable AquaPiston® flushing
KOHLER’s AquaPiston canister is designed to optimize water flow from the tank and increase the power and effectiveness of the flush.
Easier everyday cleaning
The one-piece construction eliminates the traditional seam between the tank and bowl, while the concealed trapway creates a smoother exterior with fewer difficult-to-clean contours.
Comfortable chair-height seating
KOHLER Comfort Height® provides chair-height seating designed to make sitting down and standing up easier for most adults.
Versatile, timeless design
The Cimarron blends contemporary lines with traditional styling, making it an easy fit for everything from a primary bathroom renovation to a straightforward replacement of an older toilet.
Flushing System
Proven AquaPiston® Performance
The KOHLER CimarronOne-piece toilet uses a gravity-fed AquaPiston® canister flushing system engineered to deliver a strong, efficient flush using just 1.28 gallons of water.
Unlike a traditional flapper-style flush valve, AquaPiston uses a canister design that allows water to enter the bowl from all sides of the valve. KOHLER describes this as 360-degree water flow designed to increase the power and effectiveness of the flush.
What makes this system effective:
AquaPiston® canister
Optimizes the release of water from the tank, using gravity and rapid water movement to support effective flushing.
360-degree water flow
The canister allows water to flow through the flush valve from all sides rather than relying on the opening of a conventional flapper.
2⅛-inch fully glazed trapway
The fully glazed internal trapway helps support smooth and efficient waste movement through the toilet.
Durable canister design
KOHLER states that the canister has 90% less exposed seal material than a traditional 3-inch flapper, helping resist conditions that can lead to wear, shrinking and swelling over time. It also requires less force to actuate than a traditional flapper.
Efficient 1.28 GPF performance
The Cimarron uses 1.28 gallons per flush and is EPA WaterSense® certified.
For homeowners replacing an older toilet because of recurring clogs, inefficient water use or outdated flushing components, the Cimarron provides a proven gravity-flush platform in a more refined one-piece design.
Construction & Design
Streamlined Design That Is Easier to Maintain
The Cimarron combines KOHLER’s established flushing technology with a versatile one-piece design suitable for both traditional and contemporary bathrooms.
One-piece construction
The tank and bowl are integrated into a single fixture, eliminating the seam found between the tank and bowl of a traditional two-piece toilet. That creates a cleaner appearance and one less area where dust and grime can collect.
Concealed trapway
Rather than exposing the curves of the internal trapway on the sides of the toilet, the Cimarron uses a smoother concealed-trapway design that improves appearance while making the exterior easier to wipe down.
Clean Caps® low-profile bolt caps
KOHLER uses low-profile Clean Caps to cover the toilet’s mounting hardware for a more finished appearance and easier cleaning.
Durable vitreous china
The Cimarron is constructed from vitreous china for long-term residential use.
Reveal® Quiet-Close™ seat included
The Cimarron One-piece toilet includes KOHLER’s Reveal® Quiet-Close™ elongated seat, designed to close gradually rather than slamming shut.
Designed for Everyday Comfort
The KOHLER Cimarron combines Comfort Height® seating with an elongated bowl, giving homeowners additional room and a more chair-like seating position.
KOHLER lists the bowl height at approximately 16½ inches before the seat, putting the finished seating surface at approximately chair height. The elongated bowl provides additional front-to-back room compared with a round-front toilet. The dimensional drawing on page 3 of KOHLER’s specification sheet shows the K-3619 at approximately 29 9/16 inches long, 18 15/16 inches wide and 28¾ inches high.
The toilet is also ADA compliant when installed according to applicable accessibility requirements, including appropriate placement of the flush control.
This combination makes the Cimarron particularly well suited for primary bathrooms, aging-in-place upgrades and households that prefer a taller toilet over traditional standard-height models.
