How to Tighten a Loose Toilet Seat With a Screwdriver

A few minutes with some basic tools can keep your toilet seat from wobbling. However, if the seat itself is in poor condition, this is a good time to purchase and install a new seat.

Find the Bolts

Some toilet seat bolts are exposed, but most just have a plastic flap that snaps closed to cover them. Use a screwdriver to pry these plastic covers open to expose the bolts that secure the seat to the top of the toilet bowl.

Tighten the Bolts

If the bolts have slotted heads, then tighten them by turning clockwise with a screwdriver until they are tight. Tighten the bolts evenly on each side, so that the toilet seat sits level.

If the bolt just spins without tightening, then use pliers to grip the nut threaded onto the mounting bolt from below the toilet as you tighten the bolt from above with a screwdriver. Most toilets seats use steel screws, but on cheaper seats with plastic bolts, be careful not to break the bolts or strip the threads.


Do not over tighten and crack the toilet.

Tighten From Below

If necessary, you can tighten the mounting nut from underneath. From under the bowl, turn the toilet seat nuts clockwise until they are tight. A ratchet wrench with a deep socket is usually the easiest way to tighten these bolts, but an adjustable wrench can also be used.

Replace the Bolts (Optional)

If the toilet seat bolts break or refuse to tighten, you can purchase replacement bolts at a hardware or home improvement store. Bolts that are frozen may have to be cut off with a hacksaw blade. Use only the blade (not the hacksaw), because it is very thin and it will fit under the head of the bolt; it can usually cut the bolt without scraping the porcelain on the bowl. There are also short-handle or mini-hacksaws that are a good choice for working in tight spaces.

How to fix a loose toilet seat

Confused is that your toilet seat does not have the usual lower bolts to tighten it? If you need instructions, then this article has some good tips on how to fix a loose toilet seat with no access. well, then your toilet seat can be unique in construction, so a special program is needed to secure it with the rest of the toilet.

So you notice that your toilet seat is a little loose lately and you want to screw it back into place. But you have a problem: you can not find the usual bolt under it. disassembled, you still can not find a way out. The good time has passed, here are the necessary tools and appropriate technology that will provide you with a solution, how to fix a loose toilet seat with no access the bottom.

Most models of toilet seats use simple holes as the lower access is connected to the toilet. As a rule, the hole is where you lock the toilet in the seat with screws and bolts. But there are still other types of seats that use slightly different structural holes and ways of connecting seats, but do not worry, you can solve this dilemma yourself. So first let’s see what you might want to have here.

Oh, one more important thing to do, check the toilet guarantee and see what conditions can be invalid. Fixation of the toilet seat may sometimes require you to temporarily change the appearance of the toilet (in rare cases – permanent). And the toilet function remains the same, which can cancel the toilet order, so be attentive.

Necessary tools and gears you need to work

You do not need anything specialized here, all you need is a wrench, a screwdriver, a pair of pliers and a lever tool, preferably a flat gear or something that does not damage the seat too much and gives you an ideal lever handle. Although it is not mandatory, wearing protective accessories such as glasses and gloves is not a bad idea. You can deal with unpredictable debris and splits and even viral infections in the process of looking for a way to tighten the seat.

The procedure of tightening the toilet seat

Step 1: Once again, carefully check the toilet

For example, recheck the seat hinge. There are some hidden buttons and you may not notice the bottom channel. You’ll get them there eventually. Press the button, then the lid should be released, which will reveal the fixing screws and bolts.

There is also a toilet seat with a special lid, you may have to slide it to the side or pry it up to look accessible. This is to protect the fixing bolts from water and foreign bodies that can degrade the locking mechanism. You, uh… Check carefully to detect the cover.

This is mainly used for the installation of toilets on the wall rather than on the floor. The hole for tightening the seat is located on the same side, connected to the wall with a bolt connecting the toilet to the wall, which makes it impossible to find access to the bottom if you do not remove the whole thing.

Step 2: Realign the seats

But before you try to tighten the bolts, you will need to adjust the seat. Since the seat loosens, it is possible that the seat is not aligned, you need to move it back to the center of the toilet. Several clips can be used to assist you in this process. When you are satisfied that the seat is in the correct position and rest evenly on top of the container, then proceed to the next step.

Step 3: Tighten the screws

It is better to use a screwdriver suitable for the head, not too small, not too small. Inappropriate screwdriver heads make the bolt more difficult to tighten and damage the bolt thread and shorten its overall service life. Tighten the screw until you can no longer screw it.

In this case, use pliers to fix the nut in place, while tightening the bolt with a screwdriver. The wing of the nut will lock the bolt, not allowing you to now just hold the bolt tight until your seat no longer moves forward after each tap.

Step 4: Check the tension and close the lid

But you still need to do some last-minute checks. Lightly tap the bolts to see if they move so you can be sure of the tension. Under the lid, see that there are obstacles, if not, then you are already here. Now you can use the toilet without having to support the rocking seat.


That’s the end of the tour guide, it’s easy to follow, right? The use of the toilet is very frustrating, and the loose seats constantly moving places. It is even more frustrating when you can not find the channel at the bottom to tighten the seat bolt. Step accurately and your seat will be like the first when you take you home.

This is that irritating issue that we like to avoid for some reason. Then one day, you’re sitting there and the seat suddenly shifts and your life flashes before your eyes. Then just as suddenly you find yourself still sitting there, but with the seat almost sideways as you realize that you almost fell into (or off) the toilet.

To fix this issue is so easy, you won’t even believe. This is one of the most basic types of fixes a homeowner can do without having to call someone. In most cases, it’s just that the hinge bolts have come loose.

And that’s what I’ll show you how to fix in this article.

What you need

  • package of hinge bolts (maybe… read on to see if you need them or not)
  • screwdriver (or possibly a wrench)

Just about all of the toilets I’ve ever used have toilet seats which are connected to the toilet bowl at the hinge on the back of the seat. There are two bolts here – one in each hinge.

Check the existing hinges

On the back of the seat, you should be able to flip open the hinge caps if your seat has them. Maybe the bolts are exposed. If so, that’s fine too. On mine, the bolts are covered by some flip-up caps. Flip them up if necessary and verify that both of the bolts are even still there.

Well, what do you know, the hinges on mine are both there. Then, why was it loose?

It turns out the nut on the left hinge was missing, so it wasn’t tight. Also, notice that the bolts are metal bolts. I think these were put there by the previous homeowner. All of the bolts I’ve ever seen that you buy from the store for use here are plastic.

Decide what to do

Real basic. If the bolts are both there, both have nuts, but are just loose, then all you need to do is tighten them and your job is done – you can stop reading now and go play some Yahtzee or something with your time saved.

If you want to replace them, that’s basic too…

Replacing the hinge bolts

I decided just to replace both bolts with some that I bought from the store. The replacement ones are super cheap, like around $2 or something.

They are plastic and have three parts: a bolt, a washer, and a nut.

The washer is optional. If it fits on your seat, then use it. The hinge cap area was too small on mine for the washer, so I left it off. As long as the head of the bolt is bigger than the hole in the hinge cap and won’t go through it, it’s fine.

Replace the bolts

Nothing much else to say. Take out the old bolts. Now would be a good time to remove the seat and clean the toilet around this area. There is usually a lot of nasty junk built up under and around the hinges.

Put the bolt through the top, thread the washer on from the bottom, and tighten.

Use a screwdriver or whatever is needed to tighten more. You don’t have to, but if you don’t you’ll just have to retighten the bolts more often. Even if you do tighten them with a tool right now, you’ll still likely have to retighten again at a future time.

Mine called for a screwdriver, but there are others that use a wrench.

Pat yourself on the back. But you may want to wash your hands first in case you got any of that nasty junk on them.

If your toilet seat has a reputation for coming out of the gate with a hard charge to the right, it’s time to put a stop to this mutinous mustang.

Toilet seats may loosen for a variety of reasons: the repetitive motion of raising and lowering the seat and cover, plus the fact that it’s one of the most-used places in the house. Having a loose toilet seat isn’t merely annoying; it’s also a safety concern.

So let’s put a bit in this beast!

You’ll need the following tools. Please make sure to use them carefully, as metal can easily scratch porcelain.

  • Screwdriver
  • Wrench (adjustable and/or standard)
  • Pliers

First, open the hinge caps and locate the bolts. If your seat is out of alignment, now is the time to center it on the bowl. Holding the seat in place, look under the bowl. If the bolts are attached by wing nuts, use your screwdriver to hold the bolt in place while manually tightening the wing nuts. Don’t overtighten – this could strip or break the bolt. Check to make sure the seat is tightened, then close the hinge caps.

You can also open the hinge caps and, after positioning the seat correctly on the bowl, tighten the bolts with a screwdriver, using a clockwise motion. If the bolts spin or don’t tighten, you’ll need to grip the wing nut with the pliers while tightening the top of the bolt with the screwdriver.

Have a toilet seat with metal bolts and nuts?

First you’ll need to get the toilet seat back into its proper position. Next, hold the nut in place with the wrench and then tighten the bolt with a screwdriver.

For either of these scenarios, if the seat still wiggles after you’ve tightened it, you may need to insert washers on the nut between the bolt and the underside of the toilet.

If you’re a natural-born DIYer and this is working out finer than frog’s hair, great! But if it’s starting to feel like a burr under your saddle, we’ve got the perfect solution: a toilet seat with our STA-TITE® Seat Fastening System™ that Never Loosens™.

STA-TITE® is easy to install – the lower portion of the nut is designed to snap off during installation, indicating that perfect tightness has been achieved. And when it’s time for cleaning, the hinge system lets you quickly and easily remove the seat.

How to fix a loose toilet seat

The inevitable happened, and your toilet seat is trying to throw you off every time that you use it. Why does your toilet seat loosen over time, and how do you fix the issue? This quick instruction will show you how to tighten your seat and keep it from sliding around in the near future.

Why Is My Toilet Seat Loose?

In most cases, there are only a couple of bolts securing your toilet seat to the bowl, and in many cases, at least some of the hardware is plastic. This means that as you shift your weight, sit, or cause stress to the seat, your plastic components are ground on by the bolts. Eventually, between loosening hardware and eroded plastic, your toilet seat will start to move side-to-side.

Tightening The Seat

With the majority of toilet seats, tightening is simple and can be done in minutes. Most toilet seats have plastic caps over the bolts, which can easily be “popped off” with a flathead screwdriver or similar tools. After you have access to the head of the bolt, find the screwdriver that fits the bolt threads. If you have “wingnuts” securing the bolts, these can be held while you secure the top. If not, grab your wrench set or pliers to hold the nuts in place.

Once you have the proper tools, simply tighten the bolts until the seat is completely secure on both sides, being careful not to overtighten, especially if you have plastic threads.

How To Keep It Tight

There are limited options for keeping your toilet seat tight over an extended period, however, improved hardware is a great place to start. Toilet seat components are designed to be corrosion-resistant, safe for the bowl, and more often than not, cost-effective. Completely removing the bolts, nuts, and any other pieces that are securing your seat will let you see signs of wear, which can tell that it’s time to purchase new hardware. You can buy plastic nuts and bolts that fit your seat for around $2.50, but you will end up sliding off again in a few months. Higher quality options are available, and well worth it for those who are tired of shifting toilet seats.


Tightening your toilet seat is typically a simple and fast process, as long as you are wary of overtightening. Keeping it tight, however, is the challenge. Upgrading your seat hardware can help, or you can upgrade into something more comfortable, like these state-of-the-art bidet toilet seats.

How to fix a loose toilet seat

From the pressure of people sitting to the constant opening and closing of the lid and/or seat, your toilets probably get more traffic than any other seat in the house. So it’s understandable that the seat could loosen and wiggle a bit from side to side. The bolts that attach the seat to the commode, located just behind where you sit, are causing the problem. This is no mere annoyance but a potentially unsafe situation, should the lid separate from one of its bolts while someone’s using it, causing injury. Fortunately, the fix is bound to be an easy DIY job—whether you simply need to adjust the bolts or replace them entirely. Read on for two ways to go about how to tighten a toilet seat.

Plan A: Tighten the Bolts


Locate the two bolts that attach the seat to the commode. If there are small plastic cases covering the bolts, use your fingers to pop them open the same way you might access a shampoo cap; many modern toilet seat bolt covers are manufactured with this feature. If not, use a flat head screwdriver to gently pry them loose and expose the bolts.


Use the screwdriver to tighten the toilet seat bolts, which are now exposed, screwing clockwise until they resist. Be sure to stop when each bolt stops turning; you don’t want to strip or break them altogether. Alternatively, consider adding a toilet seat hinge washer (less than $1 apiece) to each bolt. These washers were designed for the specific purpose of keeping a toilet seat in place. If you choose to do so, proceed to the next step.


To install the seat hinge, unscrew the bolts entirely using a counterclockwise motion with your screwdriver. Slip the washers into place where the bolt will meet the commode before reinserting the bolts and screwing them back.


If bolts fail to tighten, try holding the nut at the base of the bolt in place with a pair of pliers in one hand while turning the bolt clockwise with the screwdriver in the other hand. Once again, take care not to go too far and damage the bolt or strip it; once it stops turning, you’re done.

How to fix a loose toilet seat

Plan B: Replace the Bolts

TOOLS AND MATERIALS Available on Amazon
– Miniature hacksaw
– Toilet seat replacement kit
– Replacement nuts and bolts with rubber washers (optional)


If the bolts are frozen in place and just won’t budge, cut them off with a miniature hacksaw. Place the saw blade just beneath the bolt’s head and saw slowly until you’ve gone all the way through the metal.


After sawing through the bolt, the severed piece may be hot to the touch, so use caution when removing it. Repeat the process on the other bolt, then clear away any debris on both sides. Remove each nut by spinning it counterclockwise, then pull the bolts out and discard them.


If you need to replace hinges as well as the bolts, it’s best to buy a toilet seat replacement kit for less than $10 at your local hardware store. This includes nuts, bolts, and hinges with screws. Otherwise, you only need replacement nuts and bolts with rubber washers.

Then, with old or new hinges securely in place, screw the bolts in one at a time by holding each nut at the base, dropping the bolt into the center of the nut, and using your screwdriver to secure each bolt in a clockwise motion. This should do the trick to tighten the toilet seat. Test the seat to make sure it doesn’t move side to side, and you should be sitting pretty!

Does the toilet seat in your house wiggle around so much it qualifies for a thrill ride?

Not only is this a safety issue, especially for elderly or overweight guests, it removes any semblance of comfort from the “comfort station.” The reason a toilet seat comes loose in the first place is because it’s used so much. But, don’t worry, says Jamie Smith of Mr. Rooter of Baltimore. Securing a toilet seat is not nearly as hard as it seems.

The first order of business is to locate the two plastic bolts that hold the toilet seat to the bowl, says Smith. They’re in the back of the seat and are usually covered with plastic lids. Using a small screwdriver, lift the covers to expose the heads of the bolts.

Position the toilet seat in the center of the toilet before tightening the bolts. Using your fingers or a broad tip screwdriver, turn the bolts clockwise to tighten. If the bolts spin and don’t tighten, you’ll need to use pliers to grip the nut on the underside of the toilet while turning the top of the bolt with a screwdriver. Tighten until the seat stops wiggling.

Fortunately, there’s something you can do to keep the toilet seat from coming loose so often. Simply buy one of the seat tightening kits that are available at hardware or home improvement stores. These kits contain a few sets of washers which you place on the nut between bolt and the underside of the toilet. Using the tightening tool that comes with the kit, tighten the bolt till it’s snug.
