Geometric Elegance, Intelligent Comfort

The TOTO Aquia IV Cube Washlet+ C2 Toilet blends bold, architectural styling with thoughtful functionality. Its squared tank and fully skirted base create a sharp, modern aesthetic, while the 1.28 GPF DYNAMAX TORNADO FLUSH® system offers powerful performance.

Paired with the Washlet C2 seat, this model brings heated cleansing, warm air drying, and EWATER+ wand cleaning into your daily routine—all with discreet, concealed Washlet+ integration for a clean, uncluttered look.

Square Style, Customized Comfort

The Cube tank’s strong lines and fully skirted trapway give this toilet a distinct, modern presence. It supports 10″, 12″, or 14″ rough-ins with TOTO’s UniFit adapter system, allowing for flexible installation while maintaining its bold silhouette.

The Washlet C2 includes front and rear wash modes, a warm air dryer, heated seat, and an intuitive side panel control. Its low-profile design sits flush with the bowl, preserving the Cube’s crisp, symmetrical form.
The C2’s integrated side panel puts full bidet control within reach. Clear buttons and LED indicators make it easy to adjust spray temperature, pressure, and position—no remote required.

With oscillating wash modes, a heated water tank, and a three-setting air dryer, the C2 delivers many of the same features as higher-end models in a simple, streamlined package.

Easy-to-Use Controls for Every Preference

Operate all bidet functions directly from the Washlet C2’s side control panel. Adjust nozzle position, water temperature, and spray strength with clearly marked, easy-to-press buttons.

The seat also includes a SoftClose lid, built-in deodorizer, and EWATER+ wand cleaning after each use. It’s everyday cleanliness and comfort made easy, with no remote needed.

Square Design, Universal Fit

The Aquia IV Cube Washlet+ C2 Two-Piece Toilet brings a strong visual statement to your space with its squared tank and skirted design. It’s not just about looks—it’s also easier to clean, thanks to the smooth base that hides the trapway and eliminates hard-to-reach spots.

Beneath the style is the performance you expect from TOTO. The DYNAMAX TORNADO FLUSH® system delivers a quiet, 360-degree rinse using only 1.28 or 0.9 gallons per flush. Combined with the CEFIONTECT® glaze and fully integrated Washlet+ setup, this toilet delivers both beauty and function in one clean design.

TOTO Aquia IV Cube Washlet+ C2 Installation

TOTO Washlet+ systems install like a classic toilet. There are only a few additional factors to consider:

Check the size of the rough-in in your bathroom (the distance from the finished wall behind your toilet to the center of the toilet drainpipe or flange). All Washlet+ models are designed for a 12" rough-in, but if you have another size, most models have adapters available.
Access to a standard GFCI electrical outlet is required for your Washlet to function.
Your Washlet will utilize the same water connection that fills the toilet's tank via an included T-valve.
