Every WASHLET+ system comes with a high-quality TOTO toilet and matching bidet seat. These pairings are cleverly designed to conceal the bidet’s water and electric connections for a clean, streamlined look that complements your bathroom’s aesthetic.

Step 1: Customize Your Toilet

This WASHLET+ system comes with the chic and contemporary Nexus toilet. Every Nexus comes with:

  • 1.28 Gallon Single Flush

    The traditional trip lever initiates a water conserving 1.28 gallon flush that powerfully evacuates waste from the bowl.

  • Flexible Height Options

    Choose between a standard height model, with a traditional seated height of 15-17”, or a universal height model, with a taller seated height of over 17”. The taller the seated height, the easier it tends to be to get on or off the toilet.

  • Easy to Clean Silhouette

    The Nexus’ sleek, skirted base conceals the trapway, making it easier to keep the toilet clean.

Make the Nexus uniquely yours by choosing from the following customizations:

Step 2: Choose Your Bidet Seat

The Nexus toilet pairs with four of TOTO’s most popular WASHLET+ bidet seats: C2, C5, S7 & S7A.

Each of these seats comes with the same basic set of features, including a heated seat, customizable wash settings, warm air drying, scentless deodorizer, bowl premisting and nozzle sterilization.

TOTO S7A S7 C5 C2 Comparison Chart


The C2 is TOTO’s most affordable bidet seat, equipped with basic bidet features that deliver a satisfying, rejuvenating cleanse. Once you finish the bidet wash, simply pat dry with toilet paper and enjoy the fresh feeling that only a water cleanse can provide. The C2’s key functions include:

  • 3 wash modes (front/rear/soft)
  • Tank water heater provides limited warm water (30-60 seconds)
  • Side arm control panel operates the seat’s features

When simplicity and economy are your goals, the TOTO C2 is an excellent choice.



Modern-looking and packed with features, the C5 is TOTO’s popular mid-range bidet seat. Instead of a side arm control panel, the C5 is operated with a slim remote control that mounts to the wall for easy access. It offers a host of desirable wash options, including:

  • 3 wash modes (front/rear/soft)
  • Tank water heater provides limited warm water (30-60 seconds)
  • Nozzle oscillation
  • Pulse mode
  • 2 user presets
  • Warm air dryer

Designed with comfort and ease in mind, the C5 delivers a truly contemporary bidet cleanse.



Refreshment and relaxation await with the TOTO S7 & S7A bidet seats:

  • Ultra-thin silhouette
  • 4 wash modes (front/rear/soft/wide)
  • Unlimited warm water
  • Nozzle oscillation
  • Pulse mode
  • 4 user presets
  • Warm air dryer
  • Night light
  • Remote control
  • Optional auto flushing

The S7A takes convenience a step further with an auto open/close lid. From their elegant design to state-of-the-art features, the S7 and S7A embody luxury from top to bottom.
