Go look for a flushing toilet online and you will find hundreds of models from dozens of manufacturers. The sheer number of flushing toilets on the market is staggering. That can make finding one for your home very difficult.
One basic decision to make is whether to use a flushing toilet or a dry one. Dry toilets are those that use no water. The most common type used in modern homes is the flushing toilet. It’s a design that’s been around for well over a hundred years using technology that is many centuries old.
A good flushing toilet is one that does its job efficiently with a minimal amount of water. Let’s look at what features you should consider for the best flushing toilet to install in your home.
How to Choose the Best Flushing Toilet
Selecting a flushing toilet requires a bit of thought as to which features are most important. Let’s look at features you should consider when making your choice.
If there’s one thing your toilet needs, it is a powerful, efficient flush. A weak or inefficient flush means you have to push the handle multiple times to get rid of bulk waste. It also leaves behind a bit of bulk waste that you have to clean off the sides of the bowl. That’s both aggravating and a sheer waste of water.
Toilet manufacturers have come up with a number of designs and technologies to make flushing more powerful and efficient. When selecting a toilet, it’s important to investigate what technology each commode uses and how efficient it really is.
Efficient Use of Water
Flushing toilets use varying amounts of water to remove waste. Toilets manufactured for the U.S. market must use 1.6 gallons per flush or less. Efficient toilets that use 20% less water than the 1.6 gpf standard. Such toilets can earn the WaterSense certification from the EPA.
Your new toilet can last for decades with few problems. That’s why it’s important to select one that pleases the eye while also meeting your performance requirements. You will find toilets that are modern and sleek and those that are traditional and conventional.
Standard toilets are 14 to 15 inches at the rim. This is lower than the standard height of a chair seat. To make things more comfortable for taller people and those with disabilities, manufacturers make toilets at what is called comfort height, which is 16 to 18 inches at the rim. With a toilet seat added, the seat height is between 17 and 19 inches. This makes the seat height ADA compliant.
Most toilets on the market have one of two bowl shapes: round or elongated. A round toilet is the more traditional option. The rounded front does not protrude which is good for smaller bathrooms where walkable floor space is at a premium. An elongated bowl is usually two inches longer from front to back than a round one. It is more comfortable to sit on for many people, though it takes up more walkable floor space.
Price is a consideration for most people who are installing new toilets. The good news is that toilet manufacturers make models in several price categories. Some are only a few hundred dollars. They also make models that cost into the thousands. Most models fall in between the two extremes. Select a price point that works for your budget. Consider what features you need and which ones you can live without.
Manufacturers offer warranties for their products. A toilet is a rare purchase for most homeowners. Finding one with a good warranty is important to protect your investment. Some manufacturers offer one-year warranties, while others offer longer ones.
Bathrooms are often located near bedrooms and common living areas. A noisy flush can be disruptive and even embarrassing. Toilets with quieter flushes are more acceptable in residential bathrooms.
Gravity Feed vs. Pressure Assist
The two most popular types of toilet flush designs are the gravity feed and the pressure assist. Each has its advantages and disadvantages.
Most toilets are gravity feed models. That’s because it’s the original design for flushing toilets and it doesn’t require extra parts to work. Hit the lever or button. The flush valve in the tank lifts, releasing the water into the siphon. The water moves through the siphon and exits into the rim via a series of holes around the perimeter.
Gravity takes the water down the sides and out the drain. This pushes the waste through the drain and into the sewer. Once flushing is complete, the tank refills. A float shuts off the flow once the water reaches a designated height.
Manufacturers use variants of the gravity feed to make flushing more efficient and powerful. Toto, for example, developed the Double Cyclone that replaces the holes around the rim with two nozzles that direct the water down in a powerful spiral. The centrifugal force creates a more powerful flush, which removes waste using less water.
Most dual flush toilets use the gravity feed model. The main difference is that the user can select one of two flush sizes. The partial flush, which uses 60% to 80% of the tank volume, is good for liquid waste. The full flush, which uses 100% of the tank volume, is good for bulk waste.
Advantages of the Gravity Feed Model
- Proven technology. Flush toilets developed during the 19th century and have proven themselves ever since.
- Simple to install and maintain. A simple gravity feed toilet can be installed and maintained by most DIY homeowners.
- Affordable. Gravity feed toilets cost less than pressure assist models.
Disadvantages of the Gravity Feed Model
- Require more water than pressure assist models.
- Not as efficient at waste removal.
- Larger than most pressure assist models.
Pressure assist toilets are a much newer technology compared to gravity feed models. It delivers the water to the bowl with a blast of pressurized air. This propels the water at an accelerated rate, clearing the bowl more efficiently.
The inside of a pressure assist tank is a bit different. Instead of the entire tank filling with water, the water goes into a pressure vessel inside the tank. As the pressure vessel fills, it compresses the air inside. A high-pressure valve holds the water and air in place.
When the user presses the lever or button to flush, the high-pressure valve releases the contents of the pressure vessel. The compressed air pushes the water out at a much faster flow rate than a gravity feed model. The high-speed water clears the bowl quickly, often with less water.
The efficient use of water and the clearing power of the flush make the pressure assist toilet a popular choice for businesses. While pressure assist toilets have been available for residential use for decades, it’s only been in the last few years that technology has brought the cost down to where most property owners will consider it.
Advantages of Pressure Assist Toilets
- Efficient flush. They can push more bulk waste out of the drain.
- Water efficient. A pressure assist toilet typically uses 20% less water than a gravity feed model.
- Smaller. Some, but not all, pressure assist toilets are smaller.
Disadvantages of Pressure Assist Toilets
- Cost more. A pressure assist toilet will cost more than the more conventional gravity feed models.
- Requires professional installation and maintenance.
- Noisy. The pressurized flush produces more noise.

The Best Flushing Toilet is
In our comparison, the WoodBridge T-0001 is the best flushing toilet. Its modern design, efficient dual flush mechanism, and all-in-one package makes it the clear winner. It’s a toilet anyone would be proud to have in their bathroom.
The siphon brings the water from the tank into the bowl in a powerful flush that keeps the bowl clear of liquid and bulk waste. Its dual flush feature makes it very water efficient. The partial flush uses 1.0 gallons per flush and the full uses 1.6 gallons per flush. Its partial flush is powerful enough that it can be used for most purposes. A fully glazed bowl and trapway keeps waste from lingering after the flush. Its efficiency has earned it the WaterSense certification.

They include a five-year limited warranty on fading/staining of the glaze and a one-year warranty on the flushing mechanism and soft closing toilet seat. In comparison, Toto and Kohler offer only a one-year limited warranties on the toilets we compared.
The price of the WoodBridge fell in the mid-range of those we compared. While two of the Toto models were significantly less, they didn’t include all the hardware needed to do the installation. Plus, they didn’t have the modern one-piece design with an easy to clean skirt. The dual flush water efficiency makes the WoodBridge model well worth the extra cost.
Installation of the WoodBridge is more difficult than the other toilets in our comparison. However, it comes with installation instructions and a tool to help with the work required. Most DIY enthusiasts can tackle the installation without professional assistance.
One downside to the WoodBridge brand is that it can be difficult to source manufacturer parts. However, universal design parts can be used for most toilet repairs.
A powerful, efficient flush is critical for any toilet that you buy. Since toilets are items you don’t buy very often, it’s important to get a toilet that does the job, made with quality parts, that will last for decades to come. The design needs to fit into your bathroom and work with any updates you make in the future.
