Buyers Guide: What to Look For In a Good Toilet for Large Toilets

Shopping for the best toilet for your home can be overwhelming. With so many brands and models in the market, it might not be easy to choose the best brand and model to suit your needs. However, when you comprehend your needs, it becomes a bit easy to pick the right models using features.

In this article, we will help you establish the best features to look for in a large stool toilet. Always keep in mind that the price tag can never guarantee better performance. Features are what you should entirely concentrate on when buying the best toilets for large stools.

Key Feature to Look For In the Best Toilets for Large Stools 

Flushing System 

When it comes to the best toilets for large stools, the flushing system is probably the primary feature to consider before buying the toilet. For this reason, the toilet with the most powerful flushing system becomes the winner. 

There are two types of the flushing system

  1. Gravity-Feed Toilets 

The gravity system of flushing has a flush valve that entirely depends on gravity. You need a household water pressure as little as 10pounds per square inch. 3-4″ flush valves work better than 21/2 and below.  It is good to ask for full valve specs before purchasing a gravity-feed flushing system.


  • Gravity toilets are quieter than pressure-assisted toilets. They also probably work better than pressure-assisted.  


  • If you go for low price models or toilets with a small flush valve, they might not be handy.
  1. Pressure-Assisted Flushing System 

Within the sealed tank, the water compresses air and creates pressure that forcefully thrusts down the waste line. A pressure-assisted flushing system requires a minimum of 25 pounds per square inch water pressure to work correctly.


  • They dispatch the stimulated solid waste with few clogs.


  • A bit expensive 
  • Mostly noisy

Water Efficiency 

Even though flushing the large stool with a single flush is the primary key feature, choosing a toilet that will use less water in a single flush is critical. In most countries, the standard WaterSense is 1.6GPF. Some toilets like Niagara use less water of 0.8GPF, making it the winner when it comes to water conservation.  

Noisy Flush

If you are the kind of person who feels embarrassed when you disturb your guest with a noisy flushing toilet, you should consider going for gravity-feed flushing systems as they are quiet. On the other hand, the pressure-assisted flushing system makes loud sounds that are likely to wake you up at night.


You want to get a toilet that is easy to clean. One-piece toilets are a win when it comes to cleaning. However, one-piece toilets are expensive compared to two-piece toilets. Also, they are not so easy to install, and thus it will be entirely up to you to go for the most wanting needs.
