How To Choose Quiet Flush Toilet For Bathroom- The Buying Guide

Now you have several options to choose from, but still, you need assistance to make the right decision. Everything is essential, from installation to color, because you don’t want to disturb the bathroom in a short time. Take a look at my prime considerations when finding the best quiet flush toilets.

• Flush system types

There are four toilet flush types available on the market. However, you need to look at the following two types for low noise flushing toilets.

• Gravity Flush

The old flushing mechanism, the gravity flush system, was invented in 1591 and hasn’t been changed much. As the name refers, gravity flushing involves the movement of water from the toilet tank into the bowl. Users press the handle, and it opens the flapper valve to force the water into the toilet bowl.

This water fills the S-trap to create a siphon effect and simultaneously push waste into the trap and drain. A gravity flushing system is best for quiet flush toilets as it doesn’t require any electrical or mechanical assistance and uses little water pressure. It doesn’t create much noise, but just water flows through the system.

• Pressure Assisted Flush

Such flushing systems use additional pressure to flush toilet waste. The mechanism is just like the standard gravity flushing, but it uses compressed air. It forces the water through the toilet with maximum power and clears water quickly.

Along with a typical water tank, it features a secondary tank. This is the pressure vessel to mix air and water to increase pressure. Such pressurized water is shot into the toilet.

Pressure-assisted flushing is commonly used in tankless toilets. Rather than separate tanks, this type of flushing pressurizes the water directly from the inlet valve. Other functions of the flushing mechanism work the same.

However, pressure-assisted toilets are louder than gravity flush toilets as they have extra pressure.

• Double cyclone flush

One of the fancy flushing systems, the double cyclone toilet, has two side-facing nozzles under the rim to force the water to swirl in the toilet bowl. This result is a cyclone to remove waste effectively.

A double cyclone doesn’t rely on maximum pressure than gravity flush, but it may produce loud noise due to the more significant water movement. TOTO invented the cyclone system and tornado flushing system.

A double cyclone system involves three jets instead of the nozzle to create more water pressure. However, this flush system is louder, and you don’t need to consider this one if you are looking for quiet flush toilets.

• Dual flush

The dual flushing toilet is getting popular due to its more efficient water usage. Instead of a flush handle, these toilets have two buttons on the top. When you press them, they open the flapper valve and let gravity do the trick.

These buttons release various amounts of water, such as more for solid waste and less for liquid waste.

The half or partial flush option is ideal for quiet flushing and uses less than a gallon of water. However, they are more prone to leakage as compared to flush handles. The debris can easily get trapped in the flushing procedure.

• Flush type

The flush type is essential to consider for quiet flushing toilets. In simple words, less water produces less noise. There are two types of flush to choose from.

• Single flush

These toilets offer a single option for how much water flows through the toilet. Some efficient models may use around 1.6 gallons of water per flush. A single flush toilet can make a set amount of noise. Modern toilets produce noise from 40 dB to 80dB.

• Dual flush

Dual flush is discussed above, but we didn’t share the available options. There are two types of dual flush, including half and full. The advantage of dual flush is that you can easily flush away liquids with less water. Manufacturers claim that dual flush helps to save up to 67% water as compared to single flush.

When it comes to quiet flushing, a dual flush is ideal as a half flush utilizes less water and produces less noise.

• Toilet design

Although the toilet design doesn’t have much impact on its noise level but it is advised to pick the right one for your bathroom. Toilets with skirting help with noise level as the system are more enclosed.

When selecting a super quiet toilet, here are recommendations for you.

• One Piece toilet design

One-piece toilets have a bowl and tank to form a single unit. The design of one-piece toilets is sleek and modern, but they are difficult to install due to their heavy weight. They offer less adjustability with the rough-in, and the distance between the mounting holes and the wall is limited. You can’t adjust the toilet based on problems with wall dimensions.

• Two-piece toilet design

These types of toilets have separate bowls and tanks. Installation is effortless as you can quickly move the pieces own. Also, you can easily adjust the rough in based on the installation space; if needed, you can quickly reposition the bowl and tank for better fitting.

Two-piece toilet designs are recommended for small bathrooms as they are tall rather than long.

• Concealed, visible, and skirted tramways

Tramways that bend on the back behind the bowl are hard to clean. A toilet with concealed trapway has a smooth surface where the trapway appears.

Skirted trap ways feature a clean line from the front to the back. Both help clean the toilet conveniently and provide a sleek appearance.

• Comfort

One can’t deny the importance of comfort when buying a toilet. You don’t want to sit on a slippery or hard toilet. Take a look at these three features for maximum comfort.

• Toilet seat

The seat plays an essential role in toilet comfort. High-end toilets have heated seats or cleansing attachments which are designed for an ultra-comfortable experience.

For noise issues, soft closing toilets are best as they don’t produce loud slams. Whether you have kids or elderly persons, make sure the toilet you choose has a soft closing seat. If the toilet doesn’t have such a seat, you can easily upgrade the buying the new one from the market.

• The height

The standard toilet height is 15 inches, but most people find tall toilets easy to sit on with lesser stress on the back. However, you can choose a toilet with a height of 19 or 17 inches for maximum comfort.

• Toilet bowl shape

You have three toilet bowl shapes to choose from that include round, elongated, and compact elongated.

Round toilets have a circular shape and provide a decent comfort level. However, round bowl toilets are not ideal for small bathrooms.

Elongated toilets have an oval shape and are longer than round bowl toilets. The extra length of these toilets provides ideal comfort.

The compact elongated toilet is a blend of round and elongated design. They feature a compact footprint and provide a super comfortable experience.

Useful Tips For Quiet Flush Toilets

Most people consider flush is responsible for causing noise issues. However, the following factors also contribute to the loud toilet noises.

• Leaks

A leaky system may create noise that is not loud but continuous and irritating.

• Seat

A soft, closed toilet seat helps to get rid of loud bangs caused by dropping a seat.

• Air in the system

Sometimes you experience a whistle or scream in the toilet. This is due to the air in the system and can be highly unpleasant.

• Multi-functioning parts

A broken fill valve creates whistle noises and can be extremely loud sometimes.

• Build-up in pipes

Hard water creates calcium build-up in your pipes which affects water flow. It can make the toilet whoosh.

These problems should not impact the design while settling on the best quiet flushing toilet. However, it is essential to maintain the toilet regularly and replace damaged parts if they make a noise.

Make sure to replace rubber seals every few years, as being in the water causes them to perish.

Standard toilets have a 40dB to 80dB sound level when flushing.

Toilet experts recommend choosing gravity flush systems as they have ideal water efficiency. They use less water and produce less noise.

Final words

Finding a quiet flushing toilet is like finding peace of mind, especially in quiet early mornings and cold late nights. Quiet flush toilets are the best solution to deal with nasty noises. From flushing to the toilet seat, everything matters when you are dealing with loud toilet noise. Therefore, make a list of features you want in your toilet, measure the bathroom space, set your budget, and select the best quiet flush toilet for your bathroom.
