Turn a mundane trip to the bathroom into the ultimate cleaning experience with the Toto Washlet Elongated Bidet Seat from Costco. This electronic bidet toilet seat is fairly easy to install on your current toilet with a few basic tools (not included). The Washlet is designed to provide a higher level of cleanliness and comfort from the heated seat, to the self-cleaning wand that extends from under the seat to deliver soothing warm water and give you a clean feeling. It also has a warm air dryer reducing the need for toilet paper and an automatic air deodorizer to minimize odors.

Installation Tips

Do-It-Yourself Installation

  1. The WASHLET fits most toilets that feature a standard design.
  2. Check the dimensions of your toilet to ensure proper fit and installation.
  3. Check to ensure adequate space across the width of the tank. French curves may inhibit proper installation of the WASHLET.
  4. Be sure that you are able to access the tank’s fill valve inlet in order to complete the water connection. If space is limited, extenders are available at many hardware stores.
  5. Remove your current seat.
  6. Install the WASHLET base plate. The rubber grommets can be lubricated with water if needed. Tighten the screws completely.
  7. Slide the WASHLET onto the base plate. Check the fit on your toilet and readjust the base plate as needed. A quick release button on the right-hand side allows for easy removal.
  8. Connect the tee connector to your fill valve inlet. Connect the WASHLET hose and reconnect the water supply hose.
