Coway Bidet Installation: A Step-by-Step Guide


In this article, we will guide you through the process of installing a Coway bidet. Bidets have become increasingly popular in recent years, as they offer a more hygienic and environmentally friendly alternative to traditional toilet paper. Coway is a reputable brand known for its high-quality bidets, and with this step-by-step guide, you’ll have your new bidet up and running in no time.

Tools and Materials

Before beginning the installation process, gather the following tools and materials:

  • Adjustable wrench
  • Screwdriver
  • Plumber’s tape
  • Towel or cloth for cleanup
  • Coway bidet with included components (mounting bracket, T-connector, filter, and hoses)

Preparing for Installation

Disconnect Water Supply

First, turn off the water supply to your toilet by locating the shutoff valve, usually found behind the toilet or on the wall. Turn the valve clockwise until it’s completely closed. Flush the toilet to empty the tank and remove any remaining water.

Remove Existing Toilet Seat

Next, remove the existing toilet seat by unscrewing the bolts that hold it in place. If the bolts are tightly secured, use an adjustable wrench to loosen them. Once the bolts are removed, lift the seat off the toilet.

Clean Toilet Surface

Before installing the bidet, clean the toilet surface where the bidet will be attached. This ensures a proper seal and prevents any leaks or damage.

Installing the Bidet

Attach Mounting Bracket

Position the mounting bracket on the toilet rim, aligning the holes on the bracket with the holes on the toilet. Secure the bracket in place using the provided screws, making sure it is firmly attached to the toilet.

Align Bidet with Bracket

Place the Coway bidet on the mounting bracket, ensuring the bidet’s attachment points align with the bracket’s hooks. Press down on the bidet until it clicks into place.

Connect Bidet to Water Supply

Attach the T-connector to the shutoff valve by wrapping plumber’s tape around the threads and screwing it on securely. Connect one end of the provided hose to the T-connector and the other end to the inlet on the bidet. Make sure all connections are tight to prevent leaks.

Install Filter

The Coway bidet includes a filter to ensure clean water is used during operation. Connect the filter to the bidet according to the manufacturer’s instructions.

Connect Power Cord

Plug the bidet’s power cord into a nearby electrical outlet. If an outlet is not available, consider hiring a professional electrician to install one.

Testing the Bidet

Once the bidet is installed, turn the water supply back on by turning the shutoff valve counterclockwise. Check for any leaks around the connections. If there are no leaks, test the bidet by pressing the wash function on the control panel or remote. Ensure that the water flow and spray functions are working correctly.

Adjusting Settings

Customize Water Pressure

Coway bidets allow you to adjust the water pressure to your personal preference. Using the control panel or remote, select the desired pressure level from the available options. Test the different pressure settings to find the one that is most comfortable for you.

Set Water Temperature

You can also set the water temperature for the bidet. Choose from the available temperature settings on the control panel or remote. It’s important to test the water temperature before use to avoid any discomfort or potential burns.

Choose Spray Type

Coway bidets come with various spray types for a personalized cleaning experience. Browse through the available spray options on the control panel or remote and select the one that best suits your needs.


Filter Replacement

To ensure optimal performance and maintain water quality, replace the bidet’s filter according to the manufacturer’s recommended schedule. This typically ranges from every six months to a year, depending on usage and water quality in your area.

Cleaning the Nozzle

It’s essential to keep the bidet’s nozzle clean for hygienic purposes. Most Coway bidets feature a self-cleaning function that can be activated using the control panel or remote. Additionally, you can manually clean the nozzle with a soft cloth and mild soap if necessary.
