Clean Curves, Elevated Experience

The TOTO Aquia IV Arc Washlet+ C2 Toilet blends soft, modern curves with efficient performance and accessible bidet functionality. Its two-piece construction features a low-profile tank and a fully skirted bowl that’s both stylish and easy to maintain.

Paired with the Washlet C2 seat, this model provides warm water cleansing, a heated seat, warm air drying, and EWATER+ wand cleaning—all concealed within TOTO’s sleek Washlet+ system that hides cords and connections from view.

Smooth Integration. Reliable Comfort.

The Aquia IV Arc’s skirted bowl and subtle tank curvature give it a softer, more transitional look than other modern toilets. Its two-piece configuration supports 10″, 12″, or 14″ rough-ins using TOTO’s UniFit adapter, making it a flexible choice for a variety of bathroom layouts.

The Washlet C2 seat integrates smoothly with the bowl and includes front and rear cleansing, adjustable spray pressure, a warm air dryer, and an intuitive side panel control—all designed to make daily hygiene more comfortable and effective.
The Washlet C2 is operated using a side panel attached directly to the seat. With clearly labeled buttons and LED indicators, it’s easy for users of all ages to adjust wash and dry settings.

Functions include rear and front wash with oscillation, adjustable water temperature and pressure, and a three-level air dryer. The panel’s low-profile design blends cleanly into the seat for a cohesive and uncluttered appearance.

Simple Controls, Powerful Features

The Washlet C2’s side control panel offers intuitive access to all key bidet features. Adjust nozzle position, spray strength, and water temperature with a single touch, then activate the warm air dryer for a complete hands-free experience.

Additional features include a heated seat, EWATER+ wand cleaning after each use, and a SoftClose lid. Together, they enhance daily hygiene while blending seamlessly with the Aquia IV Arc’s refined profile.

Formed for Style and Comfort

With its graceful curves and gently rounded tank, the Aquia IV Arc stands out as the softest silhouette in the Aquia line. The fully skirted base hides the trapway and makes cleaning the exterior fast and easy. This two-piece model uses a low-profile tank for a balanced, modern appearance and fits seamlessly into both classic and contemporary bathrooms.

Beneath the beauty is TOTO’s DYNAMAX TORNADO FLUSH®, which uses dual nozzles to create a powerful, 360-degree flush using only 1.28 or 0.9 gallons of water. The CEFIONTECT® ceramic glaze keeps the bowl cleaner for longer by preventing waste from clinging to the surface, reducing the need for frequent scrubbing.

TOTO Aquia IV Arc 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.
