This is a simple guide that takes you slowly, yet steadily through the process of toilet seat replacement which is actually an easy process.

Soon enough you will able to go into any bathroom stall and mentally replace a toilet seat there as if you were an expert plumber training for the world plumb-lympics.

Here's What You'll Need to replace a toilet seat

Here's what you'll need:

  • New toilet seat: Obviously if you are going to change a toilet seat, then you will need your replacement because a seat is necessary for a toilet. Unless you’re planning to squat.
  • Ruler or measuring tape: Make sure the ruler is long enough to cover the entire length of your toilet seat.
  • Screwdriver: The tip of the screwdriver should match the head of the bolt; allen or cross head, etc.
Equipment and tools

    Pliers: You’ll need it to stabilize the nut while taking out the bolt.
  • check
    Penetration Oil: In case the bolt gives you a hard time due to rust, this oil will do you a huge favor.

The Steps to installing your new toilet seat

  • Step 1: Measure the size of your toilet seat to make sure it’s the standard size. You’ll want to take note of the distance between the two bolts, the length and width of the seat itself from the widest area.
  • Step 2: Buy a suitable toilet seat that matches those measurements.
  • Step 3: Remove the old seat by unscrewing the two bolts holding it in place. Use the pliers to keep the nut stable as you turn the bolt around until it slips through the nut; if the bolt is stuck against the nut due to a bit of rust, or is giving you a hard time, it is better if you add penetrating oil around the nut and let it sit throughout the night.

    Step 4: Scrub the surface with baking soda to clean around the holes just in case there is any rust.

    Step 5: Position the new seat by aligning its two holes directly above the two holes in the toilet, put the bolts through and tighten the nuts by hand. After you reach a point where using your hands is no longer effective, it is time to use a pair of pliers and your screwdriver to finish off the job. Hold the nut in place as you screw the bolt as far as possible into the nut. At the same time, you need to make sure not to go crazy on the tightening because that might cause your porcelain to crack or break which is a very annoying thing to have happen to your toilet.

    Step 6: In case there are protective caps provided with the bolts, make sure to pop those in place, as well.

    Step 7: Sit down and see how it feels. Please do not say “drafty” since it is an overused joke that has been milked dry by television series and movies.

Final Thoughts

Learning how to fix a toilet seat is quite an easy task, as this guide have shown you.

However, you just have to keep a few things in mind.

First, always double check your measurements and jot them down on a piece of paper or on your mobile. 

Second, make sure you have the same type of screwdriver tip as your bolt heads for easy screwing and removing.

Third and last, be careful of the fact that you need to keep the bolts tight to avoid the seat sliding around yet, not too tight that the pressure gets to the porcelain and it starts cracking; it’s never fun when that happens.
