How to Fix a Wobbly Toilet Seat and Lid that Keeps Falling Off

Toilets are one of the most commonly used bathroom fixtures in any home. The seat and lid are toilet components that we constantly encounter.

They take a significant toll in terms of wear and tear due to constant use. As a result, it’s not surprising if your toilet seat or lid eventually breaks.

How to Fix a Wobbly Toilet Seat and Lid that Keeps Falling Off

These specific problems typically occur when the fastening bolts become loose, the hinges wear out, or the lid cannot be securely held in place when open. This results in the lid falling.

Fortunately, you can fix most plumbing problems yourself rather than hiring a plumber, which can be quite expensive for a simple task. If you have this issue, we have a detailed article on how to fix a falling toilet lid.

In this post we have covered:

Why does my toilet lid keep falling off?

A toilet lid that keeps falling can be a nuisance whenever you want to use the toilet, and the need to fix this problem may arise. But first, let’s look at why your toilet lid won’t stay up when using the toilet.

1. Seat Placement Is Too Far Back In the Direction of the Tank

The most common reason for your toilet seat not staying up is that the seat could have been placed too far back in the tank’s direction. When a brand-new toilet is installed, the toilet seat angle is usually set beyond 90 degrees to the bowl.

The toilet seat needs to rest comfortably on the toilet tank after installation. If this angle is less than 90 degrees, the toilet seat will keep falling for whatever reason.

If you are in such a situation, here’s how to fix this problem. What you need: a screwdriver and pliers.

The seat is attached by two bolts at its rear that can be covered with nuts underneath. The nuts need to be loosened and removed, which may or may not be a problem depending on the age and condition of the toilet.

When turning nuts with pliers, be careful not to let the pliers slip and hit the toilet or something else. If you feel this might occur, protect areas close to the workspace.

Unscrew the seat and move it forward as far as you can away from the tank, then screw it back. This should give the seat that extra length and angle to stay up.

2. The Toilet Seat May Be Too Thick/Heavy

Another possible explanation is that the toilet seat is too thick or heavy. This may happen if you have the wrong toilet seat and lid combination.

As a result, the seat will not be able to support its weight. This will result in the toilet seat falling every time you open the lid.

Another reason your toilet seat cover might be heavier than the toilet seat is that this adds that extra weight, which shifts the balance of the toilet seat, making it fall every time.

In such a case, getting the correct toilet lid size may be the only solution to resolving the problem of imbalances. Remove the old seat and take it to your local hardware or home improvement store to match it up. There are all kinds of varieties, and finding one suitable for you should be easy.

If not, your seat cover will be too heavy, and you’ll keep having this problem.

3. The Toilet Is Not Level

Sometimes, your toilet may have been installed incorrectly and is not level, causing the seat to keep falling. Close your toilet lid, grab a level, and place it on the closed lid to test this.

If you don’t have a level, take your smartphone; go to the apps store (play store or apple store). Download a leveling or measuring app, then use your smartphone as a level, as stated above.

If your level shows that your toilet is slanting either to the front or back, you will need to buy toilet wedges. They are easy to install and inexpensive to purchase.

These wedges look like tiny door stops. They are placed by sliding them under the base of your toilet to make it level, depending on which side is slanting.

Since your toilet seat does not sit upright, you must place these wedges at the front of the toilet’s base. It counteracts that shift and levels the toilet. After this is done, take your level and measure. If it is level, check with the toilet seat to ensure it sits upright.

4. A Cracked or Broken Seat

A cracked or broken toilet seat can be a nuisance and cause the seat to not hold up properly. Changing your toilet seat is not a very difficult task.

You can find different styles of replacement seats on the market. All you have to do is pick one that suits you, and you are on your way.

Be careful to select the right size. There are only two standard sizes: the elongated and the round, so this should not be a problem.

All you need to do is lift the toilet seat and remove the two nuts on the hinges that hold the seat on the toilet bowl. After removing the nuts, you can lift the seat off.

Use some rust penetrant to loosen the nuts if they are rusted or corroded and not coming off easily. After removing the seat, place the new seat on the toilet and tighten the nuts.

Simply ensure that the toilet seat is properly installed so that you do not have to deal with the toilet lid not staying in place in the future.

5. Misuse of the Toilet

Repeatedly slamming the toilet seat may cause a lot of damage to the seat, hinges, and screws. If you live with reckless individuals who do this, getting a toilet seat that has slow-close hinges is the wisest way to go.

The slow-close hinges prevent the toilet seat from being slammed, therefore preventing any damage to the seat. Slow-close toilet seats have multiple advantages that will definitely make your seat and lid last longer and prevent potential damage from constant use.

6. Installation of Rubber Toilet Seat Washers

Due to misuse or just the daily closing and opening of the lid, the screws in the seat cover may loosen over time. If you notice this issue, you should consider purchasing washers.

They are not expensive, and they are easy to install. Then, unscrew the toilet seat and lid. Place the washers between the screws and the toilet seat. This will give the seat more support and make it last longer.

7. Cleaning the Screw Hinge

It is possible for residue to build up under the hinges and screws over time and cause your toilet lid not to open properly. To fix this, you must remove the screws using the proper screwdriver. If the screws keep spinning, use pliers to hold the nuts from the other side.

This should untighten the screws. After removing the seat, clean where the screws were and the hinges, using a clean cloth. Clean thoroughly to get rid of all the dust that has gathered to allow the hinge mechanism to move freely then reinstalling the seat and cover.

This will ensure the seat and the lid are free of dust and dirt that prevent the lid from opening and closing freely.

8. A Wobbly Or Lose Toilet Seat

A wobbly or loose toilet seat could be the reason it keeps falling. It’s critical that you fix a loose toilet seat because it’s uncomfortable, sometimes aggravating, and can prove very dangerous.

Fixing this problem is just as easy as a simple do-it-yourself task for those handy with tools. The movement of the toilet seat is due to the loose screws that are holding the toilet seat.

The screws are in the back of the porcelain toilet, under the plastic caps that hold the porcelain together. Start by prying the caps off to expose the screws. Use a flat-head screwdriver. The screws can be either metal or plastic.

Place the seat in the center, then tighten each screw by twisting the screwdriver clockwise. You can use your hand or a pair of pliers to hold the nut in place to tighten it. Do the same operation on both sides of the toilet.

Afterward, wiggle the seat to see if it is sufficiently tight. Be careful not to overtighten the screws to prevent stripping the threads on the screws. Let the screws be snug, but don’t tighten them too much.

Finally, close the caps and continue to use your toilet seat.

How do you fix a Toilet Seat that Keeps Falling off?

The main reason why your toilet lid won’t stay up is because the seat is positioned too far back, thus preventing the lid from leaning properly on the toilet tank.

The appropriate solution to this problem is to reinstall the toilet seat in its proper position. This will enable the lid to lean on the toilet tank at a proper angle to prevent the lid from falling.

How do you stabilize a toilet seat?

We’ve all noticed that when we use the toilet, the seat tends to move sideways due to the toilet seat’s bolts and nuts wearing out or loosening. This can be inconvenient because it increases your chances of falling every time you use the toilet.

The good news is that stabilizing a toilet seat is as simple as tightening the loose seat with simple, readily available tools. To begin, loosen the screws and nuts that secure the toilet seat to the bowl. If you discover rusted nuts or bolts, you must replace them.

Hold the toilet seat in place, then carefully screw back the bolts and nuts, taking care not to damage the nuts because most toilet seat screws are made of plastic.

When the nuts and bolts are tightened properly and the toilet seat is firmly attached to the toilet rim, the person using the toilet will be more comfortable.

What are the different types of toilet seat fittings?

There are several fittings available for toilet seats, but the top and bottom fixings are the most common.

For the top fixing, you place the bolt through the toilet seat and the bowl hole, then tighten the bolt from the top, while for the bottom fixing, you tighten the bolt from the bottom.

They both work well and will keep your toilet seat firmly in place on the toilet bowl, further improving your toilet experience.


Toilet seats that keep failing are annoying and, to some extent, dangerous. It’s important to ensure that you, and any visitors to your bathroom, are safe and comfortable.

This nerve-racking problem needs to be resolved, and you should ensure you have the right tools and information about the problem with your toilet seat. The operation is simple, and as you have discovered, you don’t even need to call a plumber!
