3 Reasons Why a Toilet Seat Cracked & How to fix it

A toilet seat is an important part of any bathroom, so keeping it in good condition is important. Unfortunately, toilet seats sometimes crack. Here are three of the most common reasons why this happens.

A cracked toilet seat can be both unsightly and dangerous. If the crack is deep enough, it can cause you to cut yourself when you go to sit down. 

In addition, cracks in the seat can allow bacteria and other contaminants to get inside, leading to an increased risk of infection. 

Thankfully, a few simple methods exist for repairing a cracked toilet seat.

What causes toilet seats to break?

These three are the main reason behind a toilet seat being cracked. 

1. Poor-quality materials 

2. Incorrect installation 

3. Heavy use 

Poor-quality materials are often to blame for seats that crack or chip easily. 

In contrast, seats that are properly installed and made from high-quality materials should be able to withstand years of heavy use. 

Toilet seats can also break if they are used excessively. For example, if someone regularly stands on the seat to reach something high, it will eventually break. 

How do you fix a cracked toilet seat?

A cracked toilet seat can be unsightly and dangerous. Fortunately, there are a few easy ways to fix it. 

For small cracks, use super glue or epoxy. For bigger cracks, use a plumber’s putty. If your toilet seat is severely damaged beyond repair, you may need to replace it entirely.

Method 1: Use Super Glue or Epoxy

If the crack in your toilet seat is small, you may be able to simply glue it shut. First, cleanse the area around the crack with rubbing alcohol. This will help the glue adhere better. 

Next, apply a small amount of super glue or epoxy to the crack and wait for it to dry. Once it’s dry, give it a light sanding with sandpaper to smooth out any rough edges.

Method 2: Use Plumber’s Putty 

For bigger cracks, you’ll need to use a plumber’s putty. Start by spreading a generous amount of putty over the crack. 

Then, use your finger or a putty knife to smooth it out. Once it’s level with the surface of the seat, use a wet rag to remove any excess putty. 

Allow the putty to dry for 24 hours before using the toilet again. 

Method 3: Replace the Seat 

If your toilet seat is severely cracked or otherwise damaged beyond repair, you may need to replace it entirely. Here are the simple steps about How to replace a broken toilet seat?

To do this, first, remove the old seat by unscrewing the bolts that attach it to the toilet bowl. Be sure to save these bolts, as you’ll need them to attach the new seat. 

Next, line up the new seat with the holes in the bowl and screw the bolts (hand-tighten them for now). 

Once both bolts are in place, use a wrench to tighten them firmly. And that’s it! Your new toilet seat is now installed. 

How to tell if the toilet bowl is cracked?

There are several ways to tell if the toilet bowl is cracked. The first is to look for cracks in the porcelain. These can be either small or large and may or may not be visible to the naked eye.

Simply look at the outside of the bowl for cracks or chips. 

Try to check for leaks. If you see water on the floor around the toilet, it’s likely that the bowl is cracked and needs to be replaced.

Try tapping on the side of the bowl with a hammer; if it makes a hollow sound, then there’s a good chance that it’s cracked.

If your toilet bowl is cracked, it must be replaced as soon as possible. 

Cracks can cause leaks, leading to water damage and mold growth in your home.
