A toilet seat is attached to the toilet bowl with the help of some nuts and bolts. After using the toilet for a few days these nuts and bolts get loose eventually. And the toilet seat starts to slide sideways.

Actually, the holes are quite oversized than the bolts used for attaching it. The manufacturers do this thing purposely so that bolts do not make any cracks in the porcelain. And that is why the seat of the toilet slides.

So, if you are ready with all the tools required, follow the steps below:

Step 1: First, you need to inspect the toilet seat. The toilet seat should be dry when you are doing it. Lower the toilet seat and locate the screw covers at the back of the toilet seat. Use your flat-head screwdriver to open them and expose the screw heads.

Step 2: Now it is time to unscrew the bolts. You need to put the flat-head screwdriver to screw-slot to unscrew the bolts. The plastic bolts will come out easily even if you use your hand. But it is not so easy with metal bolts. If it is too tight to unscrew the metal bolt with the screwdriver you can use adjustable pliers to do so.

Step 3: Take out the nuts and the bolts. And after that take out the toilet seat as well.
It is good to clean the ceramic in this phase. Use soap water to clean up the surface. Or you can use some alcohol for this purpose.

Step 4: Now, replace the seat in the exact place. Insert screws in the screw slots. Add the adhesive washers in the slots over the screw. Slide them to the end of each bolt so that there is no gap between the seat and the bowl.

Step 5: Tighten the nuts by using your hand. You can use adjustable pliers if it is made of metal. The nut will push the adhesive washers into the holes. As a result, the seat will stop sleeping sideways.

If you can do it by yourself it’s appreciated, but if you can’t do it I will suggest you get help from an experienced plumber.

Additional Tips for You:

  • It is good to secure the bolts with an adhesive washer.
  • You can use a rubber washer instead of an adhesive one.
