Why Choose the TOTO Guinevere Series?

Many homeowners choose the TOTO Guinevere series for:

  • Classic Sculpted Styling: Graceful traditional lines, decorative base molding, and a sculpted tank offer an upscale, elegant alternative to minimalist designs.
  • Powerful TORNADO FLUSH® System: A high-efficiency 1.28 GPF system using dual-nozzles to create a powerful 360-degree centrifugal rinse that keeps the bowl spotless.
  • CEFIONTECT® Ceramic Glaze: An ultra-smooth nanoscale barrier that prevents waste and scale from clinging to the ceramic, reducing cleaning frequency.
  • Seamless One-Piece Cast: Eliminates the traditional gap between the tank and bowl, avoiding leaks and keeping dust or grime from gathering in hidden crevices.
  • WASHLET®+ Smart Integration: Specifically engineered to match seamlessly with electronic bidet seats, neatly running the water and power lines through internal channels out of sight.

How To Choose a TOTO Guinevere Toilet?

When selecting a TOTO Guinevere model, you should consider:

  • Verify Your Rough-In Size: Comes ready for a standard 12-inch configuration but can adapt to 10-inch or 14-inch setups using optional TOTO Unifit adapters.
  • Assess Seating Height Requirements: Built with an ergonomic Universal Height profile, making it a comfortable and fully ADA-compliant seating layout.
  • Match Your Hardware & Finish: Available in premium colors like Cotton, Bone, and Sedona Beige, complete with an elegant left-hand chrome trip lever.
  • Plan for Electronic Bidet Additions: Ensure a dedicated 120V GFCI outlet is installed within 3 feet of the bowl structure if pairing with a smart WASHLET+ bidet seat.
  • Review Total Footprint Layout: Check your layout clearances to ensure the bold, sculpted base molding integrates beautifully into your floor space.

Frequently Asked Questions

  • The TOTO Guinevere series is a collection of one-piece toilets that feature traditional, decorative detailing. They offer high-end classical styling combined with TOTO's elite flushing power and seamless compatibility with electronic smart bidet systems.

  • The Guinevere features a rich, traditional aesthetic with sculpted curves, classical architectural molding, and an elegant profile. Unlike standard minimalist designs, it brings timeless, old-world character to high-end bathroom environments.

  • It is a premium one-piece toilet. The decorative tank and fully skirted bowl are molded together as a single solid ceramic fixture. This avoids traditional gasket leaks over time and eliminates the awkward seam behind the seat where dirt builds up.

  • The TOTO Guinevere is a high-efficiency model that uses 1.28 gallons of water per flush (GPF). It satisfies strict green-building codes across the country, fully meeting EPA WaterSense, CALGreen, and California Energy Commission (CEC) specifications.

  • The base toilet operates completely via gravity and does not need a power source. However, if you order it as a integrated WASHLET+ bundle or plan to add an electronic bidet seat for heated seating and warm washing, you will need a nearby 120V GFCI outlet.
