Toilets are one of the unsung heroes of every household.Whether your toilet is in a powder room close to your home office or in a hallway bath near your baby’s nursery, the disturbing sound of a toilet flushing is never music to anyone’s ears.
There are several reasons why some toilets tend to be louder than others. Sometimes it’s just a simple problem with a potentially simple solution. Still, other times, there’s just no easy fix.

Comparison of the Top-Rated Quiet Flush Toilets in 2024
We’ve all heard noises coming from the toilet at one time or another. Whether they occur immediately after flushing or out of the blue, these sounds can be disturbing.
But the good news is that most toilet noises are brief, temporary, and nothing to worry about.
So before calling a costly plumber, or worse, taking matters into your own hands, being able to identify the sound is helpful.
Banging Noise
One of the more annoying, and potentially serious noises coming from a toilet is the sound of banging. Sometimes the banging sounds we hear are simply loose bolts or screws. Other times, however, a loud “water hammer” noise might actually be the water inside your pipes hitting the valve.
This is normally due to high pressure inside of the pipes. While this might seem like a small problem, it could actually be indicative of a larger issue.
Tips
1 – Start by examining and tightening all bolts on the unit. Check the screws holding your seat and lid in place as well
2 – If the problem persists, there might be a more serious problem, and calling a professional plumber would be a wise move.
Loud Echoes
The sound of water hitting pipes or porcelain can create a loud echo in your toilet when flushing. Obstructions that cause an increase in water pressure are another cause for an amplified echo.
When a pipe or valve is restricted by a clog or obstruction, the water will trickle slowly, rather than flowing smoothly.
Tips
1- Eliminate obstructions by plunging the toilet
2 – Snake the trapway
3 – Clean or replace valves
4 -Place a brick inside of a large tank to displace some of the volume.
Gurgling Sound
One cause of these noises can be water filling up a large toilet tank. As the water fills the formerly empty space, it gurgles loudly, with the remaining air in the cistern amplifying the sound.
Because of the variety of causes, gurgling or bubbling sounds can be difficult to diagnose. One of the most common issues that can cause this noise is a blockage in the sewer drain, the toilet it’self, or in a vent stack.
Tips
1 – If the toilet is clogged, plunging the toilet might do the job.
2 – Install a quiet fill valve. These flush valves fill the toilet tank below the waterline, minimizing any gurgling.
3- If nothing works, it’s probably a more serious problem, requiring professional help. Until the problem is resolved, it’s best to refrain from using the toilet.
Loud Flush or Tank Refill
Restricted, tight, or stiff valves can impact water pressure, causing a loud flush or tank refill sound. Water may also make noise when it is forced to trickle into the tank too slowly because of a restricted or closed water supply valve.
Many higher-end toilets today feature special coatings that prevent waste from adhering.
Usually, the inside of the bowl is coated to prevent skid marks. Often, the exterior also receives the same treatment, making it very easy and quick to clean.
Unfortunately, there are no such coatings on the Wellworth. It’s still finished in a high gloss, so waste won’t stick too easily. However, it does seem that you’ll need to clean this toilet more often than others that we’ve used.
We noticed that at first, the water level in the bowl was too low, which was causing this problem to appear worse than it really is.
There’s an adjustment in the tank so you can change the standing water level in the bowl. Once we made the proper adjustments, the problem was minimized, though still existed.
Even with the water level set correctly, the lack of a special coating on the bowl meant that we had to clean the bowl regularly to prevent it from becoming a nasty mess.
Leak Issues We Noticed
Usually, when we experience leaks on a toilet, it’s involving the internals, a supply line, or a fitting. But with the Wellworth, we had an entirely different experience.
When the toilet arrived, we noticed a tiny hairline crack in the tank. It only took a few months for this to start slowly leaking a small dribble of water.
Through our research, we also discovered that similar issues had occurred with other Wellworth toilets. Worse, some of them seem to arrive in good condition but then develop cracks that lead to leaks with regular use.
If the china on your toilet cracks and begins to leak, the entire toilet will need to be replaced.
This is a great dual flush toilet if you’re looking for one with a handle versus buttons that you commonly see. Customers mention seeing fewer clogs and a powerful flush with this toilet. One buyer sums it up nicely – “This toilet is amazing! Flushes very quickly with very little water. I have installed two of them. Good value.”

Frequently Asked Questions
Are Tankless Toilets Less Noisy?
Although it may seem like tankless toilets are less noisy, it still depends on many other factors, like the pressure and the amount of water a toilet needs. If a toilet needs a lot of pressure to provide a powerful flush, it is more likely to be loud. The same goes for the amount of water.
Is there a quiet flushing toilet?
Yes, there are many quiet flush toilets. Flushing noise depends on a toilet’s flushing system. More advanced systems tend to have reduced noise.
What is the least noisy toilet?
The quietest toilet on the market is the Kohler Wellworth. The toilet is a fantastic unit overall, as it’s design maximizes both comfort and efficiency. The Wellworth’s low water consumption and quiet flush truly makes it hard to beat.
How do I make my toilet flush quieter?
To make your toilet quieter, make sure to tighten every pipe. Afterwards, look into the tank to see if there’s any underlying issue that’s causing excessive noise, such as an improperly adjusted flapper.
You can also adjust your water level in the tank by adjusting the fill valve’s level. The lower the water in the tank, the noisier the flushes tend to be.
Are tankless toilets quiet?
While tankless toilets can be quiet, not every tankless toilet is equal. It all depends on the model. Some tankless toilets are equipped with noise-reducing flushing technology which drastically decreased their noise level. However, other models can produce as much noise as a conventional tank toilet.
Is tornado flush quiet?
TOTO’s Tornado Flush system is powerful yet quiet. The advanced flushing technology uses less water and produces less noise compared to it’s competitors.
Final Verdict
Don’t let a noisy toilet disrupt your sleep, threaten your privacy, or wake up your baby again! Noisy toilets are caused by common, fixable issues that you can easily identify and remedy. And if you don’t deal with the hassle, or just want to start out with a low-noise toilet, there are plenty on the marketplace to choose from. Happy flushing!
