A Complete Buying Guide for Best Quiet Flush Toilets on the Market

Loud toilets are no fun. Luckily, manufacturers in the bathroom fixture market offer tons of designs to suit a wide range of issues. This includes loud flushing!

With that said, you shouldn’t take your search for the perfect toilet lightly. There are several factors to consider before pulling the trigger.

What You Should Consider When Purchasing Quiet Flush Toilets

• Measurements

  The last thing you want to do is buy a toilet only to find out that it doesn’t fit into your bathroom! Beyond the standard footprint and size dimensions, you need to pay close attention to the rough-in size. The rough-in refers to the distance between the finished wall of your bathroom and the center of the floor drain.

  The most common rough-in size for homes is 12 inches. Though, 10 and 14-inch rough-ins do exist. It’s a good idea to take some measurements before you start shopping. The rough-in measurement is something that leaves no room for error.

• Standard vs. Dual-Flush

  Next, you need to think about the type of flushing system you want. While all flushing systems serve the same purpose, you have a couple of different options these days.

  If you want a traditional old-school flush, standard single-flush systems are the way to go. They use the same amount of water to drive waste down for every flush. Usually, these toilets use approximately 1.6 gallons per flush. They’re simple, easy to use, and have far fewer mechanics than the alternative. When it comes to the flushing system itself, there are many options. We’ll touch on some of the most popular in a moment.

  With a dual-flush system, you can choose between two different types of flushes. There’s a light flush, which typically uses less than a gallon, and the full flush, which uses the standard 1.6 gallons. Usually, the light flush is reserved for liquid waste. These fixtures are great if water conservation is a top priority.

• Flushing Technology
  

  As we mentioned earlier, there are several flushing systems available. The way that a toilet drives waste down and out of your home can affect its efficiency and overall performance.

  The most popular type of technology used is the gravity flush. As you might have guessed, these systems rely on nothing more than gravity to do the job. When you press the flushing button or push down on the lever, water from the tank is released. It then fills the bowl and forces water over the curve of the toilet’s trap. This creates a siphon effect that pulls waste and water down into the sewage system.

  Another option is a pressure-assisted flushing system. They look pretty similar to a traditional gravity flush toilet. However, hiding inside the water tank is a separate pressure tank. Basically, these toilets build pressure using your home’s water supply to forcefully push waste away. Some models also take advantage of a flushometer valve to save space.

  Finally, there are cyclonic flushing systems. This technology has the added perk of keeping your bowl clean. Rather than releasing water all at once into the bowl, these toilets divert it to hidden channels along the bowl rim. The channels have a series of small holes that are strategically angled to create a cyclone effect as the water flows through. It uses centrifugal force to pull waste down while also cleaning the sides of the bowl.

• Finish and Material

  Most quiet flush toilets these days are made out of the same material. It’s a unique type of clay called Vitreous China. The material combines several heavy-duty ingredients to create a smooth surface. Vitreous China is molded to perfection to create that iconic toilet design.

  To give your toilet some lasting durability, manufacturers will apply an extra layer of glazing. It’s meant to seal the material even further while filling any tiny pits or holes. The glaze is an important thing to look for. Not only does it make your toilet look great, but it can prevent waste from sticking to the sides of the bowl. Thus, your toilet will be easier to clean.

• Ease of Installation

  Whether you have renovation experience or not, installing your toilet shouldn’t be a difficult process. These fixtures are relatively simple and can be installed with just a little bit of know-how.

  With that said, some toilets are a bit more demanding than others. Typically, skirted toilets are more of a challenge due to the limited access you have to the floor bolts. Keep this in mind when you’re choosing a quiet flush toilet.

• Round vs. Elongated Toilet Bowls
  

  The next thing to think about is the physical shape of the bowl. You have the option to go with a round bowl or an elongated one.

  Round toilet bowls are the most common you see in homes these days. As the name would suggest, the bowls are round in shape. They’re a good choice if you’re short on space because they take up less room. Typically, the length of the bowl from front to back is 16 to 17 inches. You may want to check out our handpicked list of best compact toilets for small bathrooms.

  Commonly found in offices and commercial buildings, elongated toilets are known for being the more comfortable option. They cater to a wider range of people. The bowl is longer and takes on a more oval shape. While they are only a few inches longer than a round one, that extra space is more comfortable to use for larger folks, those with disabilities, and the elderly.

• Height Options

  Speaking of comfort, height is a big factor too. For toilets, the height refers to the distance between the floor and the top of the seat. Heights can vary from manufacturer to manufacturer. Not only that, but the design of the seat can affect the overall height of the fixture. However, there are a couple of standards that are followed.

  Standard height models are typically about 15 inches off the floor. If you want something a bit taller, you can get a comfort height unit. They are between 17 and 19 inches tall.

  Comfort height models are great because they take some of the pressure off your knees and back. Plus, they’re easier to get on and off. Comfort height toilets are ideal for the elderly as well. In fact, ADA-compliant fixtures must have a height of 17 to 19 inches.

• Water Consumption

  Toilet standards have changed a lot in the last few decades. One big thing to consider is how much water a fixture uses. Older units can use as much as 7 gallons a flush. This can be a serious hit to your wallet!

  Luckily, designs changed when new federal standards were adopted. Today, new toilets must use no more than 1.6 gallons per flush. While that figure provides great water savings over older models, you can still do better.

  Many manufacturers offer WaterSense-certified fixtures that use 1.28 gallons of water or less for every flush.

  Typically, you’ll find water-saving features on dual-flush models.

What Are the Benefits of Investing in Quiet Flush Toilets?

Why should you upgrade your toilet to a quiet-flush model? If you’re the unfortunate owner of a fixture that sounds like a vacuum going off every time you flush, I don’t have to tell you how it could change your home for the better!

Truth is, these toilets offer several benefits that most people don’t think about. They can improve the overall feel of your home and make your bathroom a more comfortable space to occupy. Here are some notable benefits:

• Quiet flush toilets provide more privacy
• They are difficult to hear in separate rooms
• Many models use less water without sacrificing power
• Reduced noise levels ensure that everyone else in the home is unbothered
• They are great for frequent urinators
• Quiet flush toilets won’t wake you or anyone else up in a jarring way

6 Types of Silent Flush Toilets On the Market?

There’s no shortage of quiet flush toilets on the market today. Flushing technology has evolved quite a bit over the last few decades. As a result, manufacturers are able to design many different kinds of toilets that are much quieter than the fixtures of yesteryear.

1. Gravity Flush

   You’ll have no problem finding a traditional gravity flush toilet. As we mentioned earlier, these are the most common types of toilets that people use in their homes. Implementing the quiet flush features are just another way to improve a classic design.

2. Pressure-Assisted Toilets

   Pressure-assisted toilets are notorious for being the loudest varieties around! Think of the last time you used a public bathroom. If you’re not used to the mechanics of a pressure-assisted flush, the loud noise probably caught you by surprise.

   Luckily, some brands have developed models that manage to keep volume levels low.

3. Dual-Flush Toilets

   Dual-flush units are becoming increasingly common nowadays as more and more people are getting conscious of their impact on the planet. These fixtures are very effective and can help you cut back as much as 67 percent of your water consumption compared to standard toilets. They’re easy to use, don’t require any special installation techniques, and can help you reduce your water bill. What’s not to like?

4. Double Cyclone Flush

   Double cyclone toilets are comparatively new, but that hasn’t stopped the technology from taking off. These fixtures are like a combination of gravity flush systems and dual-flush systems. They take advantage of gravity to get rid of waste, but they use much less water. Most use less than the federal standard. Thanks to the centrifugal force created by the cyclone water, they’re pretty powerful, too.

5. Tankless Toilets

   If you’re short on space, a top rated tankless toilet may be the way to go. These units are compact because they don’t have a built-in water tank. They’re connected directly to a water supply line, eliminating the need for a bulky tank. Yet, they perform just as good as their larger counterparts.

6. Corner Toilets

   Want to save even more space in the bathroom? Try a corner toilet. These fixtures are specially designed to fit into any standard wall corner. They have some special plumbing requirements to ensure that efficiency isn’t sacrificed. Most often, they’re used in newer builds that have some square footage challenges to overcome.

You don’t need to settle for a loud toilet. Your bathroom is supposed to be a calming space. Everyone uses it, so why not invest in an upgrade that’s going to benefit your entire home and family?
