KOHLER Kingston™ Two-Piece Elongated Toilet
Dependable KOHLER Performance for Busy Bathrooms.
The KOHLER Kingston is built for bathrooms where dependable everyday performance matters. Combining KOHLER’s Class Five® flushing technology, a fully glazed 2⅛-inch trapway, Comfort Height® seating and an elongated bowl, it is designed to deliver strong flushing performance while using just 1.28 gallons per flush.
Class Five® Flushing
Comfort Height®
Built for High-Use Spaces
Quiet-Close™ Seat Included
What sets the Kingston apart is its emphasis on durability and serviceability. KOHLER engineered the tank, bowl and, trapway to work together to create a strong siphon during flushing, while its canister-style flush valve uses gravity and controlled water movement to increase flushing effectiveness.
The result is a straightforward, hardworking toilet that makes sense for busy family bathrooms, frequently used guest baths, rental properties and other spaces where reliability matters more than decorative extras.
Why Homeowners Choose the KOHLER Kingston
For homeowners throughout Northern Virginia and Maryland who want a dependable toilet built around performance rather than luxury features, the Kingston offers a compelling combination of strong flushing, comfortable seating, durable components and practical design.
Strong Class Five® flushing
KOHLER’s Class Five® system is engineered to optimize the flow of water from the tank and create a strong siphon for effective waste removal.
Designed for frequent use
KOHLER specifically positions the Kingston for high-traffic applications, which translates well to busy homes, rental properties and bathrooms that see heavy everyday use.
Chair-height comfort
Comfort Height® provides a taller seating position designed to make sitting down and standing up easier for most adults.
Practical serviceability
Features such as the silicone seal, encapsulated bolts and sanitary guard are designed to make the toilet easier to maintain over time.
Flushing System
Class Five® Performance Built Around a Strong Siphon
The KOHLER Kingston uses Class Five® flushing technology, a gravity-fed system designed to move water quickly and efficiently from the tank into the bowl.
KOHLER states that the tank, bowl and trapway are precision-engineered to work together to create a strong siphon during each flush. The canister then helps optimize water flow from the tank, using gravity and a controlled cascade of water to increase flushing power and effectiveness.
What makes this system effective:
Class Five® canister
Optimizes water flow from the tank and helps generate the strong siphon needed for effective waste removal.
2⅛-inch fully glazed trapway
A fully glazed internal trapway helps support smooth waste movement through the toilet.
Reduced exposed seal material
KOHLER states that the canister design has 90% less exposed seal material than a traditional 3-inch flapper, helping resist conditions that can cause wear, shrinking and swelling.
Easy actuation
The canister requires less force to operate than a conventional 3-inch flapper.
Efficient 1.28 GPF performance
The Kingston uses 1.28 gallons per flush and is EPA WaterSense® certified.
For homeowners replacing an older toilet because of inconsistent flushing or repeated maintenance issues, the Kingston offers a performance-first approach without moving into a premium price category.
Construction & Design
Practical Construction Built for Everyday Use
The Kingston uses a traditional two-piece design with a separate tank and bowl, but KOHLER adds several durability and maintenance features that distinguish it from more basic replacement toilets.
Two-piece construction
The separate tank-and-bowl design is familiar, straightforward and easy to service.
Sanitary guard
A sanitary guard is incorporated where the bowl and tank meet, helping simplify cleaning around an area that can otherwise collect dust and debris.
Encapsulated bolts
KOHLER uses encapsulated bolts designed to help prevent rust and corrosion.
Easy-to-service silicone seal
The flush system incorporates a silicone seal designed for straightforward servicing.
Durable metal trip lever
The Kingston includes a polished chrome metal left-hand trip lever rather than a lightweight plastic lever.
Quiet-Close™ seat included
A Quiet-Close™ elongated toilet seat and lid are included and are designed to close gradually rather than slam.
Designed for Everyday Comfort
The KOHLER Kingston combines Comfort Height® seating with an elongated bowl, giving adults a more chair-like seating position and additional front-to-back room.
KOHLER lists the bowl at approximately 16½ inches high before the seat, making it taller than a traditional standard-height toilet. The Kingston is also ADA compliant when installed according to applicable accessibility requirements.
This combination makes it particularly appealing for:
- Busy primary bathrooms
- Taller adults
- Multi-generational households
- Aging-in-place upgrades
- High-use guest bathrooms
- Rental properties
