Step 1: Unbox the bidet attachment
What I will show in this guide is the Luxe Bidet 120 (check review for it here), which is quite popular in the market. There is no big difference between each model regarding the installation method, so you can always use it as a reference.
When I opened the box, I found they had prepared almost everything I needed for installing an attachment. It contains an attachment, a T-adaptor, a 55cm flexible hose, two circular adjustment plates with a rubber gasket. It even comes with a plastic wrench and a roll of Teflon tape.
Step 2: Prepare the tools
If possible, I prefer to use an adjustable wrench, but the plastic wrench included still can do the trick. Another tool needed is a flat screwdriver for removing the bolts on the toilet.
I also suggest getting a plastic bucket to hold the water coming out from the toilet tank.
Step 3: Turn off the shutoff valve
The shutoff valve is responsible for sending the water to the toilet. You should close it first to stop any water flow into the toilet continuously. The valve often sits behind the toilet, and you can close it by turning clockwise.
Step 4: Empty the tank
As we will disconnect the toilet water line later, we should empty the tank ahead. Flush the toilet and hold down the handle until all the water come out from the tank. Remember to check whether there is any water flowing into the tank at this moment in case the shutoff valve is not fully closed.
Step 5: Remove the toilet seat
Locate the bolts between the seat and tank. Hold the nuts under the tank and remove the bolts using a flat screwdriver. Put these bolts and nuts in a safe place because you are going to put them back later.
Now you can lift the toilet seat and place it on the side.
Step 6: Position the attachment
Put the attachment on the toilet and make sure the nozzle is in the middle of the toilet bowl. Then you need to adjust the circular adjustment plates, allowing them to align with the holes on the toilet.
Put the toilet seat on the bidet attachment bracket and secure it with the bolts and nuts we removed before.
Step 7: Attach the T-valve
Unscrew the water line from the tank inlet under the toilet water tank. Ensure there is a bucket underneath the tank to catch the water in the hose and tank.
Put the black washer into the top of the T-valve and attach the T-valve to the inlet under the tank.
Step 8: Connect the bidet attachment hose and water line to the T-valve
Connect the water line to the thread on the bottom of the T-valve and then connect the bidet hose to the other thread.
Sometimes, the ends of a bidet hose have different sizes. Therefore you should pick which one can fit the thread on the T-adaptor.
Step 9: Connect the bidet hose to the attachment inlet
Connect the other end of the bidet hose to the attachment inlet.
Step 10: Turn on the shutoff valve and have a try
Until now, you are almost done. Turn on the shutoff valve on the wall and start to use this new bidet attachment.
Extra steps for Installing dual-temp bidet attachments
If you have a hot/cold bidet attachment, the installation process could be a bit more complicated. You should locate the hot water supply under the sink nearby and turn off the shutoff valve.
Then you will need to remove the hot water line and install another T-valve on the hot water shutoff valve. Make sure you get a washer inside the T-valve.
Then you should reconnect the hot water line again to one thread of the hot water T-valve and connect the hot water bidet hose to the other thread.
The hot water shutoff valve is often located in the cabinet. To get the bidet hose or tube through, you will need to drill a hole on the side.
The last step is to attach the bidet hot water hose to the bidet attachment inlet.
How to install a bidet attachment properly? After reading this guide, I assume you already have a clear idea of what to do.
Compared to bidet seats, bidet attachments are universal. They can fit almost all the toilets in the household. You should insert the bracket under the seat, and then you can control the bidet attachment by adjusting the side panel.
As they make use of the water supply directly, you will need to install a T-valve to send water to the bidet inlet. If you have a dual-temp model, then you will install another T-valve in the hot water supply to get hot water.
You see, no complex steps in the whole process. You can get it done!
