KOHLER Highline Tall Elongated Toilet
Extra Height. Easier Sitting and Standing. Proven KOHLER Performance.
The KOHLER Highline Tall is designed for homeowners who want a higher seating position without adding unnecessary complexity. Its bowl sits approximately 19 inches from the finished floor, making it a full 2½ inches taller than KOHLER Comfort Height® toilets. KOHLER specifically designed that added height to improve comfort, accessibility and ease of sitting and standing. The Highline Tall also uses KOHLER’s Class Five® flushing system, which is engineered to optimize water flow from the tank and create an effective gravity-fed flush while using just 1.28 gallons per flush. An elongated bowl adds seating room and comfort, making this a strong Mobility Collection option for homeowners who want extra height with a simple, familiar residential toilet design.
Includes toilet, standard elongated seat, delivery, professional installation and removal of your old toilet.

Product highlights
Why homeowners choose the Highline Tall
For homeowners throughout Northern Virginia and Maryland who find conventional toilets too low, the Highline Tall provides meaningful additional height without moving into a specialty-looking or technology-heavy fixture.
19-inch tall seating
The bowl rim measures approximately 19 inches high, giving it a noticeably higher seating position than KOHLER’s standard Comfort Height® toilets.
Easier sitting and standing
Because the seating position is higher, users do not need to lower themselves as far to sit or rise from as low a position when standing.
Proven Class Five® flushing
KOHLER’s Class Five® canister system is designed to optimize water flow from the tank and increase the effectiveness of the gravity-fed flush.
Elongated comfort
The elongated bowl provides additional front-to-back seating room compared with a round-front toilet.
Flushing System
Class Five® Performance Designed for Everyday Reliability
The Highline Tall uses KOHLER’s Class Five® canister flushing system, a gravity-fed design engineered for dependable everyday performance.
Class Five® canister
KOHLER says the canister optimizes water flow out of the tank, harnessing gravity and a strong cascade of water to increase flushing power and effectiveness.
2⅛-inch trapway
The toilet uses a 2⅛-inch trapway, helping support efficient waste movement.
Efficient 1.28 GPF operation
The Highline Tall uses 1.28 gallons per flush and is EPA WaterSense® certified.
For homeowners who want a taller toilet but do not need automatic bowl cleaning or premium smart features, the Highline Tall provides a straightforward combination of height, comfort and proven KOHLER flushing.
Construction & Design
Familiar Two-Piece Construction With Simple Residential Styling
The Highline Tall uses a traditional two-piece configuration with a separate tank and bowl.
Two-piece design
The familiar construction keeps the toilet straightforward, serviceable and well suited to residential replacement projects.
Seat selected separately
KOHLER sells the seat separately and recommends a compatible elongated Quiet-Close™ seat. ToiletKing can include an appropriate elongated seat in the installed package.
Exposed trapway
KOHLER’s technical specification identifies the Highline Tall as having an exposed trapway. Kohler TechComm
Elongated bowl
The elongated bowl adds room and comfort compared with a round-front toilet.
DESIGNED FOR MOBILITY
Why the 19-inch height matters
The Corbelle Tall is designed to provide more height without making the bathroom feel clinical or institutional.
Its 19-inch bowl height creates a noticeably higher seating position than standard or chair-height toilets.
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 elongated bowl adds additional front-to-back seating room, while the skirted exterior gives the toilet a more refined appearance than many mobility-oriented models.
