Seamless Style, One-Piece Design

The TOTO Aquia IV Washlet+ C5 One-Piece Toilet is a sleek, modern fixture that blends efficiency, comfort, and style. Its one-piece construction and fully skirted base eliminate gaps and crevices, making the exterior easier to clean while offering a contemporary, streamlined appearance.

With an elongated bowl and Universal Height seat, it delivers ergonomic comfort for a wide range of users. The concealed Washlet+ connection system keeps the power cord and water supply line hidden for a clean, integrated finish that enhances any bathroom.

Bidet Technology That Elevates Every Day

  • The Washlet C5 takes comfort and cleanliness to the next level with a full suite of customizable features. It includes front and rear warm water cleansing with oscillating and pulsating spray modes, all controlled through a slim, wireless remote. The remote also gives you access to adjustable water temperature, water pressure, and nozzle position for a personalized experience every time.

    A warm air dryer with three temperature settings and an automatic deodorizer make the C5 a complete hands-free hygiene system. EWATER+ technology cleans the wand before and after each use, while PREMIST® helps keep the bowl cleaner by spraying it with water before every flush. With user-friendly controls and premium functionality, the Washlet C5 delivers high-end performance in a compact, elegant form.

  • The Washlet C5’s wireless remote is designed for simplicity and control. Its illuminated touchpad and intuitive layout allow you to access all major bidet features at the push of a button. From spray type and temperature to pressure and position, you can tailor each function to your exact preferences.

    The remote also includes two user presets—ideal for shared households—and provides quick control of the heated seat, dryer, and deodorizer functions. Whether mounted on the wall or used handheld, the remote adds flexibility to your daily routine.

Comfort That Adjusts to You

The Washlet C5 remote gives you full control over your experience, with quick-access buttons for cleansing, drying, deodorizing, and more. Each function can be adjusted to match your comfort level, including spray strength, temperature, and wand position.

Its clean interface and backlit design make it easy to use during the day or night. Whether you're creating your own routine or switching between the two built-in user presets, the C5 ensures a tailored, spa-like experience with every use.

Efficient Performance, Built to Last

The Aquia IV Washlet+ C5 One-Piece Toilet features a clean, space-conscious silhouette with an elongated bowl and low-profile tank. Its fully skirted design makes exterior cleaning easier and contributes to a seamless, architectural look. Built at Universal Height, it provides comfort for users of all ages and abilities.

Behind the design, this toilet offers smart performance with TOTO’s DYNAMAX TORNADO FLUSH®, which delivers powerful, water-saving performance using just 1.28 or 0.9 gallons per flush. Combined with the CEFIONTECT® glaze and integrated Washlet+ connections, it’s a modern fixture that looks great and performs even better.

Aquia IV Washlet+ C5 One-Piece 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.
  • See the video guide below for installation of your new Washlet+ system!

Zero regrets

This was the right toilet/bidet and the right store to purchase from. Got a great price and the company reached out after delivery to ensure everything was okay. Love the way it looks and operates and the skirted design is easy to clean. The bidet component is customizable with a lot of options, which we appreciate.

Amazing Customer Service

Ordering online was super easy. Delivery was pretty quick. Unfortunately the toilets even thou they were on the pallet, seems like the freight company had a quick stop and took a tumble. They were super nice in helping me unpack to verify the damage and they took it back without any hesitation. I called over to House of Bidets and they asked me if i took any pictures which i did, I sent it over and within the same day we had a replacement toilet on order. Thank you for taking care of this. This is a company that I would buy from and also refer over to anyone thats looking for toilets.
