Toilet Seat Won’t Stay Up

It is annoying to enter a bathroom where the toilet seat won’t stay up. The most common reasons are poor toilet seat installation, your toilet is not level, and the toilet’s seat cover or toilet lid being too heavy/thick.

However, take a breather, for, in this write-down, we’ll give you complete detail of why your toilet seat keeps slamming down and how you can fix the issue.

4 Reasons Why the Toilet Seat Can’t Stay Up And Solutions

Seat Installed Too Far Back

When you install a new toilet, the seat angle to the bowl should be more than 90 degrees to allow the seat to rest against the toilet tank. Unfortunately, if the obtuse angle is 90 degrees or less, it is hard for the toilet seat to stay up.

The toilet seat may go too far back because the lid and seat combination loosen over time. The lid may retain its angle to stay up but not the toilet seat, creating an acute angle (below 90 degrees), which is why it can’t stay up.

The issue is caused by loose screws that allow the toilet seat to wobble and eventually fall. 

Solution

Loosen the Lid

You need to loosen the two screws that attach your toilet lid and seat to your toilet to push the bathroom seat forward. They might be loose enough to enable the bathroom seat to go back.

You can use a wrench if the caps are too tight. However, please don’t over-press the tool as it can break the plastic lid. Twist the cap clockwise and counterclockwise until it loosens and snaps off the bolt. 

Unscrew the bolts counterclockwise until they are out. Some toilets hide the tops of the screws beneath a small plastic cover. Therefore, check out, and if so, gently pop up the cap to gain access to the screws, and when through, it will snap back.

Slide the Seat Forward

Pull the seat as far to the front of the toilet bowl as possible to offer you some extra angle to keep the toilet seat up at all times.

Tighten the Lid Screws

You need to reassemble the seat by securing the loosened screws back up and the caps over the bolts. 

Analyze if your trick has worked, and if the problem isn’t fixed, you might face a different issue, as seen in our subsequent subheadings.

Toilet Not Level

If your toilet is not level, it means your toilet is the problem and not the seat. The seat falls when the toilet bowl leans to the front. The weight pushes the toilet further downward when you sit on it, causing the lid to fall on your back.

Solution

You can troubleshoot this problem using a level. Put a level on the lid to see what it reads while it is closed.

If the toilet slats forward, you need some toilet wedges or toilet shims to slide beneath your toilet base.

Because the problem is with your seat staying up, it is best if you position your shims around the front of your toilet to help you keep the extra angle you need to keep the toilet seat up.

First, check all gaps and holes at your toilet base, then insert sufficient shims to stabilize the bowl.

Do not push the shims too hard or fast to avoid damaging or moving the wax ring under your toilet, preventing the nasty water from leaking.

When installing the shims, retake your level and check whether the problem is fixed.

Toilet Lid Too Thick

 Another reason causing the toilet seat to fall is the thickness of your toilet seat combination, which makes the bathroom seat sit short of 90 degrees.

Additionally, your seat may not fit the whole fixture. Your toilet seat may be too thick to stand appropriately, making it hard to create an obtuse angle (more than 90 degrees).

A wrong-sized toilet seat deters it from standing correctly, resulting in purchasing the seat separately without focusing on the toilet dimension, thus doesn’t fit with your bowl and tank.

Solution

Remove the Cover

If you have a toilet seat cover that is heavy or padded, try removing it as it would be interfering with the proper function of the toilet seat and lid, and see whether the issue will resolve.

Try Replacing To Replace the Seat Cover

Sometimes the toilet seat itself may be old and warped or defective. Sometimes the toilet seat may be incompatible with the toilet. You can opt to replace your entire toilet seat with a new one.

Remember to pay attention to the shape-round or elongated toilet seats and the dimensions, as they come in different sizes. Therefore, choose the one that matches the toilet bowl. 

Installing the seat is pretty simple. 

Remove the caps, unscrew the bolts, and detach the old seat.

 Place the new seat in its position and secure it with a pair of bolts keeping in mind the angle; leave enough space to keep the toilet seat up, then connect the bolts.

How Can You Fix A Wobbly Toilet Seat?

A toilet can be wobbly due to old or loose washers, loose screws, or an accumulation of dirt and debris. Also, the wrong seat toilet may make the seat unstable.

The immediate thing to do is unscrew the bolts and put everything apart using a screwdriver and a wrench.

 Thoroughly clean all the toilet components using wet and some alcohol rubbing.

 Once done, get some new rubber washers that blend with your toilet seat, and then straightforwardly insert them.

 After that, reinsert the bolts and tighten them, and if your seat is wobbly, you will have to replace it with a new one.

Finally, ensure you have the correct toilet seat in place.
