Sharp Design. Smart Hygiene.

The TOTO Aquia IV Cube Washlet+ C5 Toilet brings crisp, modern styling and personalized comfort into one streamlined system. Its squared tank and fully skirted base deliver a bold, architectural silhouette, while the DYNAMAX TORNADO FLUSH® system offers dual flush efficiency at 1.28 or 0.9 GPF.

Paired with the Washlet C5 bidet seat, this setup offers front and rear warm water wash, air drying, EWATER+ wand cleaning, a deodorizer, and a backlit wireless remote—delivering a highly functional, fully integrated experience.

Modern Lines. Personalized Features.

The Cube tank’s symmetrical form and skirted trapway create a minimalist aesthetic that stands out in modern interiors. Supporting 10″, 12″, or 14″ rough-ins via TOTO’s UniFit adapter, the Aquia IV Cube fits into a variety of bathroom layouts with style and ease.

The Washlet C5 adds bidet functionality with adjustable water temperature, pressure, and nozzle position, as well as a heated seat and automatic deodorizer—all cleanly integrated with concealed power and water lines.
The Washlet C5’s wireless remote makes adjusting your bidet settings effortless. Its slim, backlit design mounts on the wall for easy access, allowing you to fine-tune spray type, drying temperature, and cleansing preferences.

With two user presets and intuitive icons, everyone in the household can enjoy a personalized washlet experience. Though the C5 doesn’t include auto lid operation, it offers comfort, control, and high-end features in a minimalist format.

Architectural Form. Flexible Fit.

The Aquia IV Cube features a fully skirted bowl, squared tank, and seamless Washlet+ integration to hide cords and hoses. The result is a clean, unified appearance from every angle.

With support for 10″, 12″, or 14″ rough-ins, it installs easily into a variety of bathrooms. The Washlet C5 installs flush to the bowl and enhances the system with premium hygiene and everyday comfort.

TOTO Aquia IV Cube Washlet+ C5 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.
