Heated Seat

Adjustable seat warming keeps you comfortable in every season. Pick the temperature that suits you, and many models add an energy-saving mode that warms the seat only when it's needed.

Deodorizer

A built-in fan and filter draw air from the bowl and neutralize odors while the seat is in use.

Instant Warm Water

Water is heated as it flows, so it's warm from the first second and never runs out, however long you use it.

Warm Air Dryer

Adjustable warm air dries you after washing, so you need little or no toilet paper.

Night Light

A soft glow lights the bowl at night, so you can find your way without switching on bright lights.
