Flushing Power
Kohler knocks it out of the park with the Santa Rosa’s flushing power, thanks to a precision-engineered tank, bowl, and trapway as well as the praiseworthy AquaPiston. The AquaPiston canister harnesses gravity to increase the power of every flush. That means no more lingering streaks or stains in your toilet bowl nor any clogs in sight!
The toilet also has a durable canister design that has 90% less exposed seal material than the usual 3” flapper, significantly decreasing the chance of leakage. The canister flush also requires lower actuation force, helping the model maximize efficiency.
The Santa Rosa uses 1.28 gallons per flush – an economical and environmental win! Compared to a traditional 1.6GPF unit, this model can save you 20 percent on your annual water bill.
Design
Let’s start with the toilet’s comfort factors. The Santa Rosa is a Comfort Height toilet standing at 16-1/2”. The toilet’s elongated bowl disperses the user’s body weight to make sitting easier as well.
The Santa Rosa comes with a Quiet-Close elongated seat that prevents lid slamming, in turn maximizing your seat’s lifespan. The Quiet-Close seat also comes with Quick-Release hinges for convenient cleaning.
This one-piece model seamlessly connects its toilet and bowl making cleaning extra simple. Instead of unnecessary nooks and crannies, the toilet flows smoothly throughout, taking away extra space where dirt and grime might hide.
The Santa Rosa is available in White, Biscuit, Dune, Almond, Ice Grey, Sandbar, Cashmere, Thunder Grey, Black Black, Innocent Blush, Mexican Sand. It comes with a bolt cap accessory pack, tank accessory pack, bowl, tank, tank cover, and trip lever.
