Types of toilet

1. Gravity-fed or gravity-flush toilet

Gravity-fed or gravity-flush toilet

This is the most common type of toilet used in the United States of America. Gravity-fed toilet holds water that drops into the bowl once the flush button is pushed. It then relies on gravity to flush the waste water down the drain. This type of toilet is best for regions that use septic systems.


  • Silent when flushed
  • Easy cleaning and maintenance
  • Parts for repair are easy to find because they are very common
  • Easy repair


  • May require multiple flushes to dispose of the waste
  • Clogs easier
  • The flush handle or the chain inside may cause a problem over time

2. Pressure-assisted toilets

Pressure-assisted toilets

Pressure-assisted toilets are very similar to gravity-fed toilets, but instead of relying on gravity, pressure-assisted toilet relies on a pressurized water system. This is done via a pressure tank that pushes air into the water tank, creating a stronger flush.


  • Can handle heavy waste that can clog the toilet, making it clog-resistant
  • Conducive for both spacious and tight toilet space
  • Conducive for areas with a weak or compromised septic system


  • Noisy when flushed
  • Expensive
  • Difficult to find parts in case repairs are needed
  • Difficult repair

3. Dual flush toilets

Dual flush toilets

Dual flush toilets feature two flush systems, one for a half flush (used for liquid waste) and the other for a full flush (used for solid or heavy waste). Because of the dual flush toilet’s water efficiency, many countries are adopting it for both commercial and residential buildings.


  • Water efficiency, saving money spent on water bills over time
  • They are good for the environment
  • They are budget-friendly
  • Ideal for areas facing water shortage


  • Regular cleaning and maintenance needed
  • Some dual-flush toilets are confusing. You may end up using the wrong button and have to flush twice, this defeats the whole purpose of the dual-flush system

4. Double cyclone flush toilets

Double cyclone flush toilets

Double cyclone flush toilets are newer designs that have swept the market. They feature two jets that flush wastewater and create a cyclone effect. Their powerful flush makes them more water efficient, saving on your water bill. Double cyclone flush toilets are great for those who have a septic system.


  • Fast and powerful flush
  • Water efficient, helping you save some bucks on water bills
  • Eco-friendly
  • Most double cyclone flush toilet features a dual flush system as well


  • Very expensive to purchase and install
  • Requires stronger plumbing system
  • Repairs are very difficult and pricey

Different styles of toilets

Now that we’ve settled on the types of toilets, let’s have a look at the various toilet styles on the market today.

1. One-piece or single-piece toilets

One-piece or single-piece toilets

One-piece or single-piece toilet consists of just a bowl and a tank installed as one structure. It is one of the most commonly used toilet styles because it is easy to clean and maintain. It is usually smaller in design, making it suitable for small or compact spaces.

  • Very durable
  • Very affordable
  • Easy to install and repair if damaged


  • Prone to damage and leakage if not maintained properly
  • Cleaning and maintaining is a real issue with double-piece toilets

Wall-mounted toilet

Wall-mounted toilets, also referred to as wall-hung toilets are toilets mounted on the wall using strong mounting hardware and the water tank built-in on or behind the wall. It is a great choice for homeowners who wish to have a modern and sleek look to their toilet space.

Types of flushing systems or mechanisms

There is one more toilet component that you should consider, and that is the flush mechanism. Choosing the right one is important as it will impact your water bill. Here are some of the best types of toilet flush mechanisms.

1. Single flush mechanism

The single flush mechanism is the traditional one you will find in most homes. It features just one type of flush for both liquid and solid wastes. It is often less expensive than other mechanisms but uses more water, which may, over time, cost more to operate.


  • Very affordable
  • Operation is very simple and straightforward
  • Easy to maintain


  • A single flush button or handle has the tendency to break easily
  • Not water efficient
  • Not environmentally friendly

2. Double flush mechanism

Although it has already been mentioned under the types section, we still have to reiterate it in this section. This flush mechanism features two flush; the half flush for liquid waste and the full flush for solid waste. They tend to be a bit more expensive than the single flush mechanism but in the long run will make up for its price.


  • Eco-friendly
  • Budget-friendly
  • This type of flush mechanism is effective in saving water


  • Expensive
  • Difficult installation

The touchless flush mechanism is a popular choice for commercial buildings around the world. They are designed with motion-sensor activators. You no longer need to have any contact with the toilet handle in order to flush, making them convenient, modern, and hygienic.
