KOHLER Kelston® ContinuousClean ST Tall Elongated Toilet
Extra Height. Easier Sitting and Standing. Proven KOHLER Performance.
The KOHLER Kelston ContinuousClean ST Tall is designed for homeowners who want a higher, easier-to-use toilet without sacrificing flushing performance or everyday cleaning features.
Its bowl sits approximately 19 1/16 inches from the finished floor, giving it a seating position 2½ inches higher than KOHLER Comfort Height® toilets. KOHLER specifically designed the added height to improve comfort, accessibility and ease of sitting and standing.
But the Kelston is more than an extra-tall toilet. It combines Revolution 360® bowl washing, AquaPiston® flushing, CleanCoat™ surface treatment and ContinuousClean ST automatic cleaner dispensing. The result is a mobility-focused toilet that also gives homeowners advanced flushing and easier maintenance.
Its elongated bowl adds seating room, while efficient 1.28 GPF operation delivers modern water efficiency. KOHLER’s current product page also emphasizes the extra-tall design specifically for enhanced comfort, accessibility, and easier sitting and standing.
Includes toilet, standard elongated seat, delivery, professional installation and removal of your old toilet.

Product highlights
Why Homeowners Choose the KOHLER Kelston Tall
For homeowners throughout Northern Virginia and Maryland who want a higher toilet with premium cleaning and flushing technology, the Kelston offers a particularly complete Mobility Collection package.
Extra-tall seating
The bowl is approximately 19 1/16 inches high, positioning it 2½ inches above KOHLER’s Comfort Height® toilets.
Easier sitting and standing
The higher seating position reduces how far a person must lower themselves to sit and how far they must rise when standing.
Automatic bowl cleaning
The ContinuousClean ST system automatically dispenses cleaning solution with every flush, helping keep the bowl cleaner between manual cleanings.
Advanced bowl washing
KOHLER’s Revolution 360® technology creates a forceful swirling motion inside the bowl to help keep it cleaner longer.
Flushing System
AquaPiston® Power With Revolution 360® Bowl Washing
The Kelston combines two established KOHLER technologies to deliver strong waste removal and enhanced bowl cleaning.
AquaPiston® canister
The AquaPiston® system optimizes water flow from the tank, using gravity and a strong cascade of water to increase the power and effectiveness of the flush.
Precision-engineered siphon
KOHLER states that the tank, bowl and trapway are engineered together to create strong siphon action during flushing.
Revolution 360® flushing
Revolution 360® generates a forceful swirling motion around the bowl to improve bowl washing and help keep it cleaner longer.
2⅛-inch fully glazed trapway
A fully glazed internal trapway helps support smooth and efficient waste movement.
Efficient 1.28 GPF performance
The Kelston uses 1.28 gallons per flush and is EPA WaterSense® certified.
For homeowners who want mobility-focused height without stepping down to a basic flushing system, the Kelston provides a strong combination of accessibility-minded design and premium KOHLER performance.
Construction & Design
Familiar Two-Piece Construction With Easier-Cleaning Features
The Kelston uses a traditional two-piece configuration with a separate tank and bowl.
Elongated bowl
The elongated bowl provides additional seating room and comfort compared with a round-front toilet.
Sanitary guard
KOHLER includes a sanitary guard where the tank and bowl meet to help simplify cleaning around that area.
CleanCoat™ surface treatment
CleanCoat™ is designed to inhibit water scale and mineral stains, helping make routine bowl maintenance easier.
DESIGNED FOR MOBILITY
Why the Extra Height Matters
The Kelston is built around a simple but important idea: a higher toilet can reduce the effort required to sit down and stand back up.
The bowl measures approximately 19 1/16 inches from the finished floor, putting it noticeably above KOHLER’s standard Comfort Height® models. The dimensional drawing on page 3 also shows the toilet at approximately 33¾ inches overall height, 29¼ inches long and 17⅝ inches wide.
That extra height may be especially appealing for:
- Adults who find conventional toilets too low
- Taller adults
- Homeowners planning for changing mobility needs
- Aging-in-place renovations
- Multi-generational households
- Anyone who prefers less bending when sitting and standing
The goal is not to make the bathroom feel institutional. The Kelston maintains familiar residential styling while adding height where it matters.

ContinuousClean ST
Automatic Bowl Cleaning With Every Flush
One of the Kelston’s biggest differentiators within the Mobility Collection is its ContinuousClean ST system.
Instead of relying solely on periodic manual bowl cleaning, ContinuousClean automatically dispenses cleaning solution during normal flushing.
Works with white toilet bowl cleaner tablets
KOHLER states that the system is compatible with any white toilet bowl cleaner tablet.
Up to six months of continuous cleaning
KOHLER states that the system is compatible with any white toilet bowl cleaner tablet.
Three cleaning technologies working together
The Kelston approaches bowl cleanliness in three different ways:
- Revolution 360® helps wash the bowl during flushing.
- ContinuousClean ST automatically introduces cleaning solution.
- CleanCoat™ helps resist mineral scale and stains.
That makes the Kelston especially appealing for homeowners who want both mobility-focused height and less day-to-day toilet maintenance.
