Factors to Consider Before Choosing the Best Low-Flow Toilet 

A toilet is an important home fixture that you naturally expect to last for a long time. If you want to get the best out of yours, there are a few things you need to take into account before purchasing one.

Shape and Size

There’s no point in having a toilet that saves a lot of water but is not comfortable enough for you to sit on. Most toilets come in three shapes – elongated or wide, round, and compact elongated. Each shape has its own merits and demerits. For a small bathroom user, a round-shaped toilet is a no brainer. However, if you have more space, an elongated shaped toilet would be ideal and more comfortable. The compact elongated shaped toilet is quite comfortable too but in a unique way. The tank is smaller. 

Mode of Installation 

This is another important factor that you need to deeply ponder. There are three most popular types of toilets – a one-piece, two-piece, and wall-hung toilet. 

  • The one-piece toilet installation is easy because you only need to install one piece.
  • Two-piece installation is cheap and in most cases comfortable for users.
  • The wall-hung installation is the hardest. It requires plumbing connectivity and you might have to break your wall.


The height of your toilet is an important conundrum you need to solve before buying. You won’t be the only person using your toilet and therefore it’s best to use a standard toilet that would fit most people. Many people often go for toilets that have the required height by the ADA. Moreover, the height of a toilet has been known to influence health issues like constipation. You don’t want to get someone constipated for using your toilet, do you?

Flush Feature 

Your toilet can either be a single or dual flush type. The dual flush type is known to have a two-button feature for flush, while the single has the traditional lever on the right-hand side. 

Frequently Asked Questions

Q: What is considered a low flow toilet?

A: A toilet is considered to be a low flow toilet when it uses less water than a traditional flush toilet and achieves the same or even better results. They mostly utilize a dual flush system, with one meant to clear urine, and the other to clear solid stubborn waste.

Q: What is a low flow toilet?

A: A low flow toilet is a type of toilet that consumes less water than a conventional toilet. It uses at most 1.6gpf and can even use less than that. Even with its low water usage, it can clear wastes effectively. Most low flow toiles clears waste either by gravity or with pressure.

Q: How does a low flow toilet work?

A: Apart from their water conservative feature, there are two operational ways a low flow toilet clears wastes – pressure-assisted and the gravity method. The former utilizes the water released from the tank to clear wastes. While the latter uses a compressed pocket of air combined with force to energize the released water which in turn clears the waste. However, all low flow toilets use at most 1.6gpf to clear wastes.

Q: How much water does a low flow toilet save?

The traditional toilet uses an average of 3.5gpf which is around 27,300 gallons per year. A low flow toilet uses an average of 1.6gpf which is 12,500 gallons of water per year. This means a low flow toilet will save you 30% more water daily.
