Things to Consider: When Buying Best Quiet Flush Toilet

When it comes to quiet flush toilets, there are several options available on the market. However, for choosing the best quiet flush toilet, you need to consider these factors. 

Toilet Flushing Types

Over the years, the toilet flushing mechanism has significantly improved. The traditional flush system, which consists of a ball and a rod floating in the tank. Eventually, get replaced with plastic and rubber flappers.

  • Gravity Flushing Toilet: Gravity flushing toilets are less noisy options available in the market. As the name suggests, Gravity flush toilets use gravity to flush the waste; they consume less amount of water. As the flush valve is pressed, water will forcefully enter the bowl and move waste through the trapway. In addition, such toilets use siphon action for removing waste.
  • Pressure-Assisted Toilet: A pressure-assist toilet is the most powerful toilet on the market. These toilets use pressurized air; the water is forcefully forced into the toilet bowl. As a result, waste can be removed efficiently and smoothly with this system.
  • Double-Cyclone: Unlike the traditional toilets, a double cyclone toilet features two nozzles on the toilet rim that create a double-cyclone effect. These flushing systems consume a low amount of water.

Bowl Shape

Toilets are generally available in two shapes: round and elongated; both shapes have their own pros and cons. 

  • Round Shaped As the name refers these toilets have round bowls, these types of toilets are suitable for compact size bathrooms.
  • Elongated Shaped: These toilets have oval shapes extending several inches. They are generally suitable for the spacy bathrooms. These toilets enhance your overall toileting experience. 

Toilet Rough-In

Toilet rough-in is one of the most important things to consider when buying a quiet toilet flush. Knowing the rough-in is quite essential before buying quiet flush toilet, you must know your toilet rough-in size. A toilet rough-in is the distance from the wall to the center of the waste outlet on the floor. Modern toilets have a 12-inch rough-in, but some older houses have 10 or 14 inches rough-in. For measuring, take a measuring tape and calculate the exact distance between the wall and the waste outlet. This way, you will be able to find a suitable toilet for your bathroom.

Flushing Type

Nowadays, toilets offer various features, and flushing is one of them. There are two types of flushing: Single and Dual flush. As the name suggests, single flush toilets use the same amount of water for removing liquid and solid waste. However, dual flush toilets allow you to pick between full and partial flush.  The full flush removes the solid waste, and the partial flush will enable you to remove liquid waste. The dual feature makes toilets environment-friendly toilets.

Bowl Height

The silent flush toilet bowl height is another important aspect to be considered when buying the best quiet flush toilet. A standard toilet bowl measures 15 to 16 inches from ground height. However, for better comfort, you can consider comfort height toilets. These toilets are 17 to 19 inches above ground height and are accredited by ADA (American with Disabilities Act.). The comfort height toilets are suitable for elderly purposes. They take pressure off the joints and muscles when sitting and standing. 


Nowadays, toilets are manufactured using vitreous china, which is durable and lasts for years. The problem is that it can leave some small pits on the surface, which naked eyes cannot see. These tiny holes allow mold and dirt to get stuck in.

To overcome the issue, manufacturers started adding a special coating, “Gloss”; it helps prevent waste from sticking to the toilet surface. As a result, with each flush, you will get a neat and clean toilet bowl. In addition, with an extra gloss coating, the toilet cleaning effort will be minimized. 

Water Consumption

Toilet water consumption is another vital thing to be considered. To determine how efficiently a toilet performs, you must check the amount of water the toilet consumes per flush. Low water consumption will significantly reduce your water bill. For example, a highly efficient toilet uses 1.28 gallons per flush (GPF), while some go as low as 0.8 GPF. Therefore, you might consider buying a water-saving toilet that consumes no more than 1.6 GPF, a standard set by WaterSense, a Federal water agency.

Toilet installation is a complicated process; an experienced plumber will charge a decent amount for toilet installation. Therefore,  you should consider an easy-to-install toilet. Usually, toilets come with an instruction list and all the essential things required for toilet installation. Usually, one-piece toilets are easier to install than two-piece toilets. However, if you are not a DIY guy, we suggest considering hiring a professional plumber for toilet installation. 

What Causes the Noise in a Toilet?

There are various reasons why a toilet flushes loudly. Mostly noise comes from the fill valve, toilet valve. The vibrating sound occurs due to the fill valve. Fill valves lose their efficiency and elasticity as they age and become damaged.

If you hear whooshing sounds when flushing, this may be caused by calcium clogging the pipes, preventing the flow of water. Also, the leak-fill valve causes a whistling sound; it can be fixed by tightening the valve.
