When it comes to toilets, there are a number of different parts that make up the entire system. These include the flapper, floater, lever arm, chain, wax seal, and other parts that may need to be replaced long before the basin itself will ever be damaged.

Reasons Why You Should Replace Your Toilet

While a toilet may last anywhere from many years, depending on the model, there are several reasons why you may need to replace it sooner.

1. Crack in the toilet bowl or tank

Not only can cracks in the toilet bowl cause unappealing aesthetic damage, but they may even trigger leakage or other problems. However, cracks in the tank could lead to a malfunction of certain parts, such as the flapper, which is why it’s best practice to replace both components simultaneously.

2. Leaks

Leaks are perhaps one of the most common reasons why homeowners need to replace their toilets. This can be caused by a number of different factors, such as cracks in the bowl or tank, loose connections, faulty seals, and more. By identifying and repairing leaks early on, you can help extend the overall lifespan of your toilet.

3. Discoloration

Over time, a toilet can begin to develop stains and discoloration that won’t easily be cleaned away. If the surface of your toilet has developed any unsightly stains, then it may be worth considering a replacement rather than investing in costly cleaning products and strategies.

4. Clogs

Another sure sign that it’s time to replace your toilet is frequent clogs. A clogged toilet can be caused by a number of factors, from poor flushing to an influx in the use of toilet paper. If you’re dealing with a clogged toilet on a regular basis, then it’s time to consider purchasing a new one.

5. Improvements

Even if your toilet is functioning properly, you may want to consider replacing it for various reasons, such as:


Today’s toilets are much more efficient than older models, using less water per flush and saving you money on your monthly utility bills.


Over time, interior design trends and styles may change, so you may want to consider replacing your old toilet with something that matches the look of your home.


If your current toilet is scratching or otherwise uncomfortable, a replacement may be in order.
