KOHLER K-4000-0 San Souci Touchless Comfort Height 1.28 GPF Elongated Toilet with AquaPiston Flushing Technology, White, 1-Piece

Enjoy a contemporary style and a more hygienic way to flush with the KOHLER San Souci touchless toilet. Combining cutting-edge technology with performance-driven design, touchless toilets let you flush the toilet without having to touch them. Just hold your hand over the tank sensor to activate the flush. With no handle to touch, there are fewer germs to pick up or leave behind.

Inside the San Souci touchless toilet you’ll see the touchless module. This little black box is filled with patented leading-edge technology: a sensor, a circuit board, a flush actuating wheel and the four AA batteries it takes to power your flush.

A metal bracket suspends the module inside the tank, high above the water line, and a simple chain connects the wheel to the flush valve. The sensor projects an electromagnetic field through the lid of the toilet and extends another 2-3” above that, and the flush will activate as you break this field with your hand. This field is intentionally tight to reduce the potential for incidental flushes. Touchless toilets run on four AA batteries that should last about 6-12 months depending on usage. A low battery indicator will beep five times before each low-battery flush when the batteries have approximately four weeks of power left, so you have ample warning when they need to be replaced. There is no trip lever thanks to touchless technology, so your tank’s exterior is smooth and easy to wipe clean. An optional emblem can be placed on the toilet’s lid above the sensor to let family members and guests know where to activate the flush. The one-piece design of the San Souci touchless toilet offers sleek, contemporary styling in a seamless, easy-to-clean design. The concealed trapway and low-profile bolt caps also make this toilet easier to clean because they create smoother surfaces with less opportunity for dirt to get stuck in hard-to-reach crevasses.

The San Souci touchless toilet features an innovative AquaPiston flush engine that delivers a fast, powerful and plug-free flush. Using the force of gravity and precision-engineered tank, bowl and trapway, this single-flush gravity toilet offers a strong siphon during flushing. The AquaPison canister allows water to flow into the bowl from all sides to increase the power and effectiveness of the flush. And this powerful flush doesn’t sacrifice water. At 1.28 gallons per flush, this toilet provides significant water savings of up to 16,500 gallons per year compared to a 3.5-gallon toilet.
