Step-by-Step Bidet Attachment Installation

Installing a bidet attachment takes 10-15 minutes with no special tools required. Most people can complete installation themselves without plumbing experience.

What You'll Need

Tools: Adjustable wrench (optional), towel or small cloth.

Materials: Your new bidet attachment, which includes all necessary connection hardware.

That's it. No power tools, no special parts, no advanced plumbing knowledge needed.

Step 1: Turn Off the Water

Locate the water shut-off valve behind your toilet, usually a small metal knob on the wall or floor. Turn it clockwise until it stops. If you can't find it or it won't turn, you may need a plumber's help with this step.

Flush the toilet to empty the tank and confirm water is off. The toilet should not refill.

Step 2: Remove Your Current Toilet Seat

Look underneath your toilet seat where it connects to the bowl. You'll see two bolts and nuts securing it. Unscrew these bolts using your hands or an adjustable wrench.

Lift the old seat off carefully. Set it aside. You won't need it anymore since the bidet attachment includes a new seat.

Step 3: Disconnect the Water Supply Hose

Locate the hose connecting the toilet tank to the wall. This is your water supply hose. Use an adjustable wrench to loosen the connection at the toilet tank end. Have a towel ready to catch any water drips.

Unscrew the connection completely and set the hose aside. Some water will drip out—this is normal and expected.

Step 4: Position Your Bidet Attachment

Place the bidet attachment on your toilet rim, centering it from front to back. The spray nozzles should point toward the center of the bowl. Most attachments have alignment marks to help position correctly.

Ensure the attachment sits securely on the rim without rocking or shifting. It should feel stable before you connect water.

Step 5: Connect the Water Supply

Attach the input hose from the bidet attachment to your water supply hose. Your bidet will include the appropriate connector. Hand-tighten this connection, then snug it another quarter-turn with your wrench.

Don't over-tighten. A quarter-turn past hand-tight is sufficient. Over-tightening can crack plastic connectors.

Step 6: Connect the Toilet Water Supply

Connect the outlet hose from your bidet attachment to the toilet tank inlet. This ensures your toilet still fills normally. Hand-tighten this connection as well.

Some attachment models have this connection built-in, so check your specific model. Most Luxe and TUSHY attachments include this.

Step 7: Install the New Toilet Seat

The bidet attachment comes with mounting hardware and a new seat. Position the hinges at the rear of the attachment and tighten the bolts underneath.

Ensure the seat is centered and level. It should not rock or shift. Tighten bolts firmly but not aggressively.

Step 8: Turn Water Back On and Test

Turn the water valve counter-clockwise slowly to restore water pressure. Watch for leaks at all connection points. A few drops are normal during the adjustment period, but steady drips indicate a loose connection.

Let the toilet fill. Once full, test the bidet. Adjust the water pressure dial to a low setting—you want to test gently before discovering your attachment's full strength.

Step 9: Adjust Settings and Preferences

Most bidet attachments include controls for water pressure and, on some models, spray pattern selection. Experiment with different settings to find your preferences.

If you have a family, each person may prefer different pressure levels. Keep your dial at a conservative setting initially.

Troubleshooting Common Issues

Water leaking from connections: Tighten the connecting nuts another quarter-turn. If this doesn't work, check that rubber washers are properly positioned.

Low water pressure: Check that your water supply valve is fully open. Sometimes the valve doesn't turn all the way or gets stuck partway.

Attachment shifts or rocks: Reposition on the rim, ensuring even contact at all mounting points. You may need to adjust how far back it sits.

Water sprays too far or not enough: Adjust your bidet's pressure dial. Most attachments have control valves that regulate spray intensity.

Maintenance After Installation

Most bidet attachments require no ongoing maintenance. However, if you notice reduced water pressure after months of use, mineral deposits may be blocking the nozzles.

Disconnect your attachment and soak all plastic parts in white vinegar for one hour. Flush with fresh water to remove mineral buildup.

That's it. You've successfully installed your bidet and can enjoy improved hygiene and comfort immediately. Most users can't imagine going back to toilet paper alone.
