KOHLER Kingston 2-piece 1.28 GPF Single Flush Elongated Toilet in White (Seat Not Included)

Single-flush gravity uses the force of gravity and a precision-engineered tank, bowl and trapway to create a strong siphon during flushing. Class Five flushing technology offers virtually plug-free performance and rinsing power for a clean bowl. Class 5 canister allows water to flow out of the tank from all sides (360), increasing the power and effectiveness of the flush.
