Quiet Flush Toilet Buying Guide

Choosing the best quiet flush toilet will typically depend on a number of factors. The most important to keep noise to a minimum, of course, is the flush mechanism. This mechanism will also impact water consumption. Here are the top considerations you must understand when selecting the best quiet flush toilet for your home:

  • Flush mechanism
  • Type of flush
  • Additional toilet noise
  • Design

Let’s take a look at each in more detail!

Flush Mechanism

When it comes to the flush mechanism, there are 4 main toilet flushing systems:

  • Gravity flush
  • Dual flush
  • Pressure-assisted flush
  • Double-cyclone flush

The first two presented are the most suitable for a silent flush toilet, however, it’s important to be aware of all of them so that you make the correct selection.

Gravity Flush

The gravity flush system is the oldest flushing mechanism, invented in 1591, and hasn’t really changed much at all. As the name implies, this mechanism uses gravity to move water from the tank into the bowl. As you press the handle, the flapper valve will open, and then the gravity forces water into the toilet bowl.

The S-trap becomes filled with water, creating a siphon effect. This simple and effective action then pushes waste into the trap and then into the drain.

This mechanism is the best for quiet flush toilets because it doesn’t need any mechanical or electrical assistance. There’s not really much to make noise other than water flowing through the system due to the low water pressure.

Dual Flush

Dual flush toilets are becoming increasingly popular in homes due to their more efficient use of water. Instead of the normal flush handle, the toilet has 2 buttons on top. When they’re pressed, they open the flapper valve and let gravity do the work. The buttons release different amounts of water, less for liquids and more for solids.

The half-flush option can be incredibly quiet and will often use less than a gallon of water. However, they’re unfortunately it’s easier for debris to get trapped in their flushing mechanism, making them more prone to leakage than flush handles. The system will need to be maintained regularly otherwise any water-saving efforts will be made redundant.

Pressure-Assisted Flush

This flushing mechanism uses added pressure similar to the standard gravity flush but with the addition of compressed air. The air forces water through the toilet with far more power and therefore can clear waste much more effectively.

Along with the standard water tank, These mechanisms require a secondary tank, known as the pressure vessel, along with the standard water tank so that the water and air can be mixed to increase pressure. The pressurized water is then shot into the toilet.

Tankless toilets often use pressure-assisted flushing where the system pressurizes the water directly from the inlet valve rather than having separate tanks. Everything else works the same. A pressure-assisted toilet is will be louder than a gravity flush due to the extra pressure in the water.

Double Cyclone Flush

The double cyclone flush is often regarded as a fancy flushing system. The toilet has 2 side-facing nozzles under the rim and these force the water to swirl in the toilet bowl. The result is a cyclone, which is effective for removing waste.

This mechanism doesn’t necessarily rely on more pressure than a gravity flush but is generally a lot noisier due to the increased velocity and movement of the water.

Type of Flush

When it comes to the type of flush, it is worth considering the following two options for quiet flush toilets, remembering that less water usually equals less noise:

  • Single flush
  • Double flush

Single Flush

In single flush toilets, you have one option for how much water flows through the toilet. They are efficient models that use around 1.6 gallons of water per flush and will make a set amount of noise. In modern systems, this will typically be anywhere from 40 to 80dB.

Dual Flush

The dual flush, as mentioned above, provides 2 flushing options: half and full. The benefit is that you can flush away liquids with less water, theoretically making them more efficient and quieter. Manufacturers will claim that dual flush toilets save up to 65-70% of water when compared to a single flush, but this isn’t always true. Any design issues will lead to significant water wastage through leakages.

Additional Toilet Noise Considerations

Sure, the flush is likely most people’s first thought with thinking about toilets making noise. But, there are many other factors that make noise to consider, such as:

  • The seat – soft-close seats eliminate the banging noise when you drop a seat.
  • Leaks – a leaky system creates noise, which might not be loud but it can certainly be irritating.
  • Malfunctioning parts – a broken fill valve will whistle and can be quite loud.
  • Air in the system – this can sound like anything from whistling to screaming and can be very unpleasant.
  • Build-up in pipes. – in hard water areas, calcium build-up in pipes affects water flow. This can make your toilet whoosh.

Most of these considerations shouldn’t impact your decision too much when settling on a quiet flushing toilet. But, it’s at least important to stay on top of these to maintain your system regularly and replace any worn parts if they’re making a noise.

Toilet Design

The type of toilet design you choose may not have much of an impact on noise levels, as the flush system is far more important. However, models with skirting might be able to help with noise levels simply because the system is more enclosed. When choosing the quietest toilet, consider the following toilet designs:

  • One-piece system
  • Two-piece system
  • Wall-mounted system

One-Piece System

A one-piece toilet system is pretty self-explanatory, this is where the bowl and tank come as a single formed unit. While these designs are sleeker and more modern, one-piece systems may present more of a challenge when it comes to installation because they’re heavier.

Two-Piece System

A two-piece toilet consists of a separate tank and bowl. Their installation is generally easier because you can move the pieces on their own. Also, they are far easier to adjust the rough-in, based on the installation area. If necessary, you can reposition the tank and bowl to fit better. A two-piece toilet system is the second-best design for compact spaces because they’re often tall rather than long.

Wall-Mounted System

A wall-mounted toilet usually houses the tank and flushing system in the wall, meaning only the bowl is exposed and insight. They’re the best for compact spaces because they take up little space in a room. However, these types of toilets are much harder to install and are usually far more expensive.


The design of the toilet is less important when looking for the best quiet flush toilet. But, is worth mentioning as it is of course a consideration when purchasing any toilet.

Shape and Dimensions

Toilets typically come in 2 standard shapes: round or elongated. The main difference is the type of seat you buy. Elongated bowls are generally 2” longer than rounded ones and are more comfortable. However, thy also take up more space.

A toilet seat should ideally be between somewhere 16” and 19”. Higher seats are better for people with mobility issues, but some people prefer lower seats because it puts them in a better position.


The color of the toilet has no bearing on it being a silent toilet and is purely a design choice. As you will already know, the standard color for a toilet is white or off-white. Of course, colored toilets do exist but these are harder to find and they’re harder to keep clean because dirt doesn’t show up on them as easily.

The quietest toilet is likely to use a flushing mechanism that produces as little sound as possible, such as the gravity flush or the dual flush, the latter having an option to flush with less water pressure. The Woodbridge T-0019 Toilet is a fine example of a quiet toilet that utilizes a gravity dual-flush, bringing super quiet and powerful flushing.

How do I make my toilet flush quieter?

To make your toilet quieter you will need to tighten everything. The first, easy thing to do is to check your pipes. After this, you may seek to adjust (lower) the water flow if the noise persists. You can adjust the pressure of the water entering the tank by opening or closing the shut-off valve while listening to the noise that it makes in the tank when re-filling.

What is a quiet flushing toilet?

Why is my toilet so loud when refilling?

When you hear a loud sound just as your tank is refilling, it may mean that there’s too much water flow inside the supply pipe. You can solve this problem by lowering the pressure of water that is allowed to pass through the pipe. To do so, you adjust the supply valve that’s located under or beside the toilet tank.
