Premium bathroom and wellness trends have seen requests for bidet seats in Kiwi bathrooms rise. When specifying these systems, it's important to ensure effective backflow prevention is incorporated. Kohler's latest innovation, the D-Shaped Bidet Seat, provides a smart solution with built-in backflow and a clean aesthetic, perfect for toilets with a D-shaped profile. 

Applications

The Englefield D-Shape Bidet Seat is designed for residential bathrooms in New Zealand, functioning as a retrofit upgrade or as part of a new installation. It is compatible with the Englefield Evora and Englefield Sierra toilet profiles (a seat template check is recommended before purchase). The seat is also available as part of two integrated toilet suites: the Evora Integrated Toilet Suite, a rimless back-to-wall design, and the Tivoli Integrated Toilet Suite, which incorporates a raised-height toilet for improved accessibility.

Key performance benefits

Built-in backflow protection

The seat includes an integrated high-hazard Atmospheric Vacuum Breaker (AVB), which prevents back-siphonage from drawing water back into the potable supply during pressure drop events such as burst mains or system maintenance. This meets NZBC G12 requirements and may reduce or eliminate the need for a separate external Reduced Pressure Zone Device — though confirmation with local authorities is recommended before installation.

Comfort and hygiene features

The seat provides instant warm water cleansing with separate front and rear wash functions, a heated seat with adjustable temperature, and warm air drying to reduce toilet paper use. Antibacterial materials are used for the seat and wand. A soft night light and single-handed remote control support everyday convenience.

Simplified installation

The integrated design consolidates backflow protection and bidet functionality into a single unit, reducing the number of components required and simplifying the installation process for plumbers. This also supports a more straightforward path to building consent compliance.

Integrated toilet suite options

For projects requiring a fully coordinated bathroom solution, the Evora and Tivoli Integrated Toilet Suites pair a rimless toilet with the D-Shape Bidet Seat as a complete package. Both suites include the built-in AVB, instant warm water cleansing, heated seat, warm air drying, and night light. The Tivoli suite's raised-height design makes it suited to accessible bathroom applications.

Warranty and maintenance

The Englefield D-Shape Bidet Seat is backed by a three-year warranty. The antibacterial seat and wand materials support ongoing hygiene with minimal maintenance requirements.
