7 Best Quiet Flush Toilets - [Quietest Toilet Reviews 2023] (2024)

Toto MS604114CEFG UltraMax

CHECK LATEST PRICE

Our best overall pick out of all the quiet flushing toilets we’ll be reviewing today is the Toto UltraMax toilet.

This toilet is a high-efficiency unit that only uses 1.28 gallons of water per flush.

For context, the average modern-day toilet is designed to use 1.6 gallons per flush, so the Toto UltraMax toilet is clearly more efficient than average.

Despite using less water per flush, the Toto Ultramax manages to remain powerful. The tornado flush system clears any waste in a matter of seconds.

This is also facilitated by the CEFIONTECT lubricating glaze on the inside of the bowl, which stops particles from clinging to the inside of your system.

What really makes this toilet stand out from the competition, however, is that it not only flushes efficiently, but also quietly.

And the flush isn’t the only thing that’s quiet about this toilet. The seat also operates on a soft-close system that prevents it from dropping suddenly and creating a noise disturbance.

Moreover, this toilet is 28 ¾ inches tall, which is deemed universal height. This means that the toilet is optimally designed to suit as many people of different heights as possible.

Our only small criticism of the Toto toilet’s design is that the cistern is slightly slanted.

A lot of people like to use the top of their toilet’s water tank as a shelving spot for toilet paper, air freshener, or other toilet-related items.

Therefore, this feature of the design may be a disappointment for some buyers.

Pros

• 1.28 gallons per flush - Highly efficient
• Tornado flush - Powerful and quiet
• Lubricating glaze - Minimal particle adhesion
• Softclose seat - No unexpected seat noises
• Universal height - Optimal size to suit people of all heights

Cons

• Slanted cistern - Difficult to use for toilet tissue or other accessories

WOODBRIDGE T-0019 Toilet

CHECK LATEST PRICE

The Woodbridge T-0019 toilet is a close competitor with the Toto Ultramax, so it takes second place in our list of quietest toilets.

The Woodbridge T-0019 uses a siphon flush system that is quiet but also powerful. The flush system has been rated at 1000g according to the Map scoring system, which is about as good as you can get.

In addition to the quiet flush, the T-0019 also features a soft-closing seat, so if you drop the seat by accident in the middle of the night, there’s nothing to worry about!

Thanks to the glazed bowl, the inside of this toilet is resistant to marks and stubborn particles. The smooth design, which is free of sharp corners or any difficult-to-clean areas, can be wiped down in a matter of seconds for the easiest toilet clean of your life.

Finally, we also love that the necessary tools and hardware for installation are included with the purchase of this toilet. The requisite bolts and wrench come in the package, so there’s no need to go out and buy specialist tools to install your new toilet.

With that being said, there have been a small number of reports of this toilet leaking after installation. Clearly, this is not the experience of all buyers, so we can put this down to lapses in quality control or imperfect installation.

Pros

• Siphon flush - Quiet but powerful
• Soft-closing seat - Minimizes accidental noise
• Glazed bowl - Mark-resistant
• Smooth design - Easy to clean
• Includes floor bolts and wrench - No extra purchases required for installation

Cons

• Some reports of system leaking - May indicate an issue with quality control

American Standard Dual Flush Toilet

CHECK LATEST PRICE

We’ve chosen the American Standard Dual Flush Elongated Toilet as our runner-up pick.

The American Standard Dual Flush toilet features a high-efficiency flush that can use either 1 or 1.6 gallons of water per flush, depending on your requirements.

The flush system is a siphon dual flush, which is both powerful enough to clear waste effectively and quiet enough not to cause too much of a disturbance every time you activate the system.

We particularly like that this toilet features a powerwash rim that cleans down the inside of the bowl thoroughly with every flush, minimizing the amount of cleaning you need to do after the fact.

The sanitary damn positioned at the back of the bowl ensures that particles accumulate in an area that the powerwash can access, meaning that you won’t be left with an accumulation of waste particles in hard-to-clean areas.

Thanks to the EverClean treated surface of both the inside and outside of this toilet means that it will remain as sanitary as possible between cleaning sessions with no mold, mildew, or fungal growth.

Taller individuals may struggle with the design of this toilet, however, since it is very compact.

Pros

• 1 - 1.6 gallon flush - High efficiency
• Siphon dual flush - Quiet and effective
• Powerwash rim - Cleans with each flush
• Sanitary dam - Prevents particle accumulation
• EverClean surface - Prevents mold and fungal growth

Cons

• Compact design - May be too small for taller buyers

HOROW HWMT-8733 Small Toilet

CHECK LATEST PRICE

Our first highly commended pick for quietest toilet is the Horow HWMT-8733 Small Toilet model.

The siphon flush system is highly efficient - in fact, it’s one of the more efficient systems on our list. It can use as little as 0.8 gallons per flush, although there is the option of a 1.28 gallon flush for heavier-duty flushes.

Because the inside of the bowl is fully glazed, no matter which flush you use, the Horow toilet will help you to keep your bowl clean.

In addition to all of this, the Horow Small Toilet comes at an affordable price, with the requisite floor bolts for installation included.

This should save you some money on both the product itself and on extra purchases if you’re sticking to a budget.

As with our runner-up pick, however, this toilet is designed to be as compact as possible to fit into smaller spaces.

While this is definitely a plus if you don’t have a lot of bathroom space to work with, it could be an issue for taller customers.

Pros

• Siphon flush - Highly efficient and very quiet toilet flush
• Compact build - Suitable for small spaces
• Fully glazed - Minimizes cleaning
• Affordably priced - Budget-friendly
• Floor bolts included - Ready to install

Cons

• Small design - Not the best choice for taller people

Kohler K-3589-0 Cimarron Comfort Height Elongated Toilet

CHECK LATEST PRICE

Next up, we’d like to introduce you to the Kohler Cimarron Comfort Height Elongated Toilet.

The Kohler Comfort Height toilet is a high-efficiency toilet, flushing at a rate of 1.28 gallons per flush while minimizing flush noise for a quiet bathroom experience.

Kohler’s Comfort Height Elongated design means that the average adult should have no trouble sitting down comfortably on this unit.

The seating area is long enough to accommodate most frames, while the height of the toilet surpasses that of the average unit by 2 inches, meaning that people who are slightly taller than average can use the unit in a comfortable position.

Possibly the best thing about this toilet, however, is that it uses Aqua-piston technology.

This advanced technology means that in addition to being quiet and powerful, the Kohler toilet flush is extra-fast and anti-clogging.

Unfortunately, the compatible toilet seat is not included with the purchase of the Kohler Comfort Height toilet, so you will need to buy this separately.

Pros

• 1.28-gallon quiet flush - High-efficiency without the noise
• 2 inches over average height - Designed for comfort
• Elongated design - Plenty of seating space
• Aqua-piston technology - Quick flush without clogging

Cons

• Seat not included - Separate purchase required

Niagara Stealth Toilet

CHECK LATEST PRICE

The Niagra Stealth Toilet boldly proclaims its low noise levels in its product name, and we’re pleased to confirm that the system definitely lives up to it!

Like most of the toilets in our selection today, the Niagra Stealth toilet is a highly efficient model. Only using 0.8 gallons of water for every quiet flush, you’ll definitely notice some savings on your water bill.

Because the flush works using gravity as opposed to other methods, the flush manages to be very quiet as well as effective and water-efficient.

This is because there’s none of the usual pressure involved in flushing out the water, which is often what can cause a lot of noise.

The elongated bowl design makes this a comfortable toilet to sit on, even for long periods of time.

Once again, however, the Niagra Stealth toilet does not come with the seat, so this will need to be purchased separately before you can complete the installation.

Pros

• 0.8 gallons per flush - Very efficient
• Gravity flush system - Impressively quiet toilet
• Elongated bowl - Comfortable to sit on

Cons

• No seat included - Extra purchase needed for complete installation

Convenient Height Extra Tall Toilet

CHECK LATEST PRICE

Finally, if you’re specifically looking for a quiet flushing toilet designed for taller individuals, we have just the thing! Check out the Extra Tall Toilet model from Convenient Height!

The Convenient Height Extra Tall Toilet has both a light or economy flush for saving water (0.9 gallons per flush) and a heavy-duty flush that uses 1.28 gallons.

This means you can easily tailor your water consumption to your needs.

Thanks to the gravity flush system, the flush is extremely quiet since there’s no loud pressure noise to contend with.

Additionally, because the Convenient Height Extra Tall Toilet is, as advertised, extra tall (20 inches), it’s comfortable for taller individuals to get on and off without any knee discomfort.

We should mention, however, that the flush handle is relatively fragile and is liable to break when handled roughly, so please handle the flush lever with care if you do opt for this toilet.

Pros

• 0.9 gallon light flush - Saves water
• 1.28-gallon heavy flush - Powerful
• Gravity flush system - Very quiet toilet
• 20-inch height - Built for taller buyers

Cons

• Flush handle is fragile - Handle with care
