Clean Curves, Elevated Experience

The TOTO Aquia IV Arc Washlet+ C5 pairs modern styling with advanced bidet functionality. With a fully skirted base and soft tank contours, this toilet brings a sleek aesthetic to your bathroom. The efficient 1.28 GPF DYNAMAX TORNADO FLUSH® system ensures powerful performance with every flush.

The included Washlet C5 bidet seat adds comfort and hygiene with warm water cleansing, a warm air dryer, deodorizer, and a wireless remote—all seamlessly integrated with hidden connections for a refined, built-in look.

Thoughtful Features in a Streamlined Form

The Aquia IV Arc’s smooth tank shape and skirted trapway give it a refined, transitional profile. Its two-piece construction supports 10″, 12″, or 14″ rough-ins via TOTO’s UniFit adapter, offering flexibility during installation without compromising aesthetics.

The Washlet C5 seat fits flush with the bowl and includes front and rear cleansing, a heated seat, adjustable spray, and an automatic deodorizer. With no exposed cords or hoses, this setup looks polished from every angle.
The Washlet C5’s slim, wall-mounted remote provides intuitive access to all functions, including spray adjustments, drying options, and water temperature control. Soft backlighting ensures easy visibility in any lighting.

Two programmable user presets allow multiple users to save their preferred settings. While it doesn’t offer auto-lid control, the C5 delivers personalized comfort and hygienic performance in a user-friendly design.

TOTO Aquia IV Arc 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.
