Just like most Kohler collections, the Tresham collection comes in a variety of sizes, flushing set-ups, and accessories. We take a closer look at one of the most decked-out models – the K-3981-RA!

Flushing Power

The Tresham K-3981-RA model has a precision-engineered tank that harnesses the power of gravity to maximize siphon strength. Every flush removes waste in a matter of seconds without leaving streaks or stains behind.

The model is also equipped with an AquaPiston canister that increases flushing power by letting water flow in from a 360 degree angle. The toilet’s 3:2 flush valve ratio further optimizes flush performance thanks to a durable canister design that has 90% less exposed seal material than traditional three-inch flappers. Reduced exposure means reduced chance of leakage.

The K-3981-RA’s light-touch canister flush has a lower actuation force than traditional flappers, so every flush is effective and hassle-free. The toilet uses 1.28 gallons per flush, a cost-saving and environmentally friendly water usage

Smart Design

The K-3981-RA is a one-piece unit that seamlessly blends its bowl and tank together. The model’s angular structure and crown-like molding give the toilet a nice, chic feel. Thanks to its skirted trapway, you’ll only spend a minimal amount of time cleaning the toilet, as there’s not much space for dirt and grime to hide.

The K-3981-RA has a Comfort Height of 16.5” and comes with an elongated bowl, making it ADA-compliant; a right-hand polished chrome trip lever is also included. A Quiet-Close seat comes with the toilet, which retain the seat’s quality by preventing unintentional slamming. The seat’s quick-release hinges further simplify the cleaning process by being easily removable.

The K-3981-RA has a ReadyLock installation system that eliminates the need to drill into the floor for the traditional 12” rough-in – you won’t even need professional help to complete the job!

The model only comes in white and biscuit. A right-hand polished chrome trip lever is included.

Tresham K-3981 and K-3950 Comparison

In love with the K-3981’s design but can’t swing the price tag? The K-3950 is one of the Tresham collection’s most budget-friendly models. The model features the same cozy design as the K-3981 and many of its best features, such as the 1.28gpf, AquaPiston flushing system, and ADA-compliant design. However, you’ll need to purchase your own seat and supply line.
