Highline Arc 12 in. Rough In 2-Piece 1.28 GFP Single Flush Elongated Chair Height Toilet in White with Soft Close Seat

Renowned for their unmatched durability and performance, KOHLER Highline toilets are a long-standing favorite among homeowners and professionals alike. The Highline Arc 2-Piece Elongated Toilet continues this legacy with an updated design featuring a sophisticated flared tank, a powerful Class 5 flush system, and Comfort Height® seating. Combining timeless aesthetics with modern functionality, this toilet is an ideal solution for both contemporary and traditional bathrooms.

Designed for maximum flushing power and water efficiency, the Highline Arc delivers 1.28 gallons per flush (GPF) — saving up to 16,500 gallons of water annually compared to outdated 3.5 GPF toilets. It meets EPA WaterSense® standards, helping you conserve water without sacrificing performance.

At the heart of this toilet’s flushing system is KOHLER’s canister flush valve, engineered to produce a robust gravity-fed siphon that effectively clears waste with ease. The Class 5® flushing technology ensures virtually clog-free performance and exceptional bowl cleanliness every time.

The elongated bowl design provides additional room and comfort, while the Comfort Height® seat (comparable to standard chair height) makes sitting and standing easier for most adults — a smart ergonomic upgrade, especially for older users or anyone with mobility challenges.

The Highline Arc comes as a Complete Solution package exclusive to The Home Depot, meaning everything you need for installation is included right out of the box. This all-in-one package features the toilet bowl, tank, slow-close toilet seat, wax ring, and floor hardware. The left-hand polished chrome trip lever adds a stylish finishing touch to the overall look.

Thanks to its standard 12-inch rough-in and 3-bolt installation design, the toilet is easy to install for both homeowners and professionals. Note: the supply line is not included and should be purchased separately.

Built with KOHLER’s trusted craftsmanship and backed by industry expertise, the Highline Arc delivers the perfect blend of performance, reliability, and refined style for any bathroom upgrade.
