Whether we own our home or rent, a loose toilet seat is something we all have to deal with sooner or later – especially if we live in a large household.

The thing is:

A toilet seat that is moving around isn’t just uncomfortable to use.

In fact, it’s a potential safety hazard, as children or elderly people, in particular, might fall and injure themselves seriously.

No need to worry, though:

A wobbly toilet seat is quick and easy to deal with.

And at Plumbing Superstore, we’re going to show you exactly how to tighten a toilet seat in no time!

Read on.

How to fix a loose toilet seat

Before you get to work, make sure you wear gloves since even a spotless-looking toilet is likely to have at least some dirt or germs somewhere. Besides, most toilet cleaning products contain large amounts of bleach and strong chemicals that may irritate or even damage your skin.


Most toilet seats are attached to the toilet with two long toilet seat screws that go through the porcelain. In many older models, these are actually mounted from the bottom rather than from the top.

You can easily check if you’re dealing with one of those by looking at the underside of your toilet at the back.

Do you see any protruding screws?

Try them to see if they’re loose. If that’s the case, centre the toilet seat and tighten the nut from below with a ratchet wrench or a pair of pliers – no need for a specific toilet seat tightening tool.

Be extra careful when working with plastic screws, as they’re liable to snap if you apply too much pressure. This is one of those occasions when it’s best not to follow Maxïmo Park’s lead and ‘wait and see how things turn out if you apply some pressure’ even if you’re a massive fan of the Newcastle-based alt-rock band.

This shouldn’t really be an issue when working with steel screws.

Give the toilet seat a try. If it’s still a bit loose, you’ll have to tighten the toilet seat bolts from the top.

Start by finding the screws on the top. In these models, they’re typically found just behind the seat and covered with plastic flaps. Use a slotted screwdriver to lift the caps and then tighten the screws as necessary.

Plumbing Superstore pro tip: Don’t overtighten steel screws, as you might crack the toilet bowl.

If none of this has worked and your toilet seat is still wobbly, you’ll probably have to replace the bolts. In that case, it’s a good idea to buy a toilet seat fixing kit, which comes complete with everything you need to get the job done, including rubber washers you can fit underneath the bowl.


By this point, you’re probably wondering how to tighten a toilet seat with no access underside and hidden fixings, right?

After all, these models are far more popular in the UK than the older ones.

Don’t go anywhere:

That’s exactly what we’re going to zoom in on next.

How to tighten a toilet seat with hidden fixings

To tighten a toilet seat with concealed fixings, you’ll have to remove the toilet seat first.

With the seat up, go ahead and locate the release mechanism. More often than not, it’s a pair of metal buttons on the inside of the seat, directly above the wobbly metal caps. Other models might feature a single release button in the centre, but this design is less common.

Either way, simply press the release mechanism and lift the seat carefully.

Then, take off the metal caps to reveal the screws next to the metal anchors. Make sure the anchors are evenly spaced so that the toilet seat isn’t crooked. Once you’re satisfied with their location, use a suitable screwdriver (in most cases, you’ll need a standard Phillips screwdriver) to tighten the screws.

Remember what we said earlier? Work carefully and don’t overtighten!

Finally, replace the metal caps and slot the toilet seat back into position, pressing down firmly until you hear the anchors click.

That’s all it takes!
