With its clean, simple design and efficient performance, this Highline® water-conserving toilet combines both style and function. An innovative 1.28-gallon flush setting provides significant water savings of up to 16,500 gallons per year, compared to an old 3.5-gallon toilet, without sacrificing flushing power. The chair-like height ensures comfortable use.

Additional Features

Round-front bowl offers an ideal solution for smaller bathrooms and powder rooms.
Comfort Height® feature offers chair-height seating that makes sitting down and standing up easier for most adults.
Class Five® canister optimizes the flow out of the tank, harnessing gravity and the natural powerful reducing cascade of water to increase the power and effectiveness of the flush.

I was surprised it didn’t come with the toilet seat or cover since both were in the product photos. Good otherwise.

Finish:Black

Very nice, but man, do you have to drop some coin for a black one. FYI, theres no seat! Youll have to dish out another Benjamin for that.

Finish:White

Highline= high quality. The aesthetic of the toilet clean and elegant. The toilet overall appears more trim in comparison to many other toilets I have seen. It installed easily. Initially, the tank delivered was broken upon arrival. I called Wayfair customer service about the broken piece and their agent handled it efficiently and sent out a replacement swiftly.
