The Best Low Flow Toilets

The Best Low Flow Toilet for Water Saving Bathrooms

Low-flow toilet

Have you ever looked at your water bill and asked yourself, “Why is it this high?!” The average four-person household goes through 400 gallons per day. That includes drinking water, showers, laundry, washing your hands, and flushing the toilet. 

We’ve all seen the PSA. “Turn off the water while brushing your teeth!” and “Limit showers to 5 minutes!” But, have you ever thought about the toilet? 

Ask yourself how many times you use the restroom. I’m not saying you should stop flushing every time, because… hygiene. But, I am saying you should consider a new toilet.

If you have an old conventional toilet, it could be using up to 7 gallons of water per flush. Newer low-flow models use as little as 1.6 gallons. 

Leaky toilets lead to even more water waste. A leaky toilet wastes up to 200 gallons of water every day. Investing in a low flow toilet will have a positive impact on your water bill and the environment.

What is a Low Flow Toilet?

The Best Low Flow Toilets for Maximum Water SavingsLow-flow toilets conserve water, save money, and limit your impact on the environment. They are the standard in new construction homes. There are two types of low-flow toilets to consider. 

  • Gravity Driven: These use a flapper in the toilet tank to release water. The water flows into the bowl, flushing the contents while gravity carries the waste out through the pipes.
  • Pressure-assisted: These have a pressure tank that works like a water balloon. The tank fills with water under pressure. When the toilet is flushed, a valve opens. A combo of pressure and gravity results in a powerful flush.

What are the Benefits of using a Low Flow Toilet?

There are many benefits to invest in a low-flow toilet. Low-flow toilets are designed to save water, save money, and save the environment. 

Save Water

A low-flow toilet significantly reduces the amount of water needed to channel waste through the plumbing system and away from your home. Each flush uses about 1.6 gallons. 

Save Money

 The EPA estimates that homeowners can save as much as $110 per year on their water bills by switching to low-flow toilets.

Environmentally Friendly

Decreased water consumption and usage help lower the impact on our environment. Many cities and counties have begun passing conservation laws requiring homeowners and landlords to install low-flow toilets.

Good Investment

You’ll quickly recoup your initial investment within a couple of years. After the initial cost, a low-flow toilet will continue to save you money for years to come. They can last up to 30 years without being replaced.

Save money


Some cities, states, and counties also offer a rebate to homeowners who replace their traditional toilets with low-flow models. Check with your local town officials to see what rebates are available in your area.

Frequently Asked Questions about Low Flow Toilets

What is better, a Dual Flush or Single Flush?

Dual flush toilets have proven to be the superior choice. A dual flush toilet has two flush types. 

  • The liquid waste flush uses just 0.8 gallons.
  • The solid waste flush uses 1.6 gallons.

Single Flush toilets are better than conventional toilets, but they use up to 5 gallons per flush. 

What is the best type of toilet for water savings?

The best type of toilet for water savings, both environmentally and economically, would be the low flow toilet. A typical low flow toilet only uses 1.6 gallons of water per flush compared to its older counterpart that uses on average 5 gallons per flush. Decreasing water usage means less money spent on your water bill. You win financially and environmentally. 

Can I install a low flow toilet by myself?

If you consider yourself a handy person, then a low flow toilet can be easily installed yourself. There are simple instructions that will allow you to accomplish the installation. There are many resources online that can help you install your low-flow toilet, such as videos and written instructions with pictures. 

Finding the right toilet for you can be accomplished by going to your local hardware or plumbing store or shop online to find the right toilet for you. Once you find the right toilet you can look over the instructions and decide to tackle the installation yourself or call your local plumber for an easy installation. 

Do low flow toilets clog more than normal toilets?

The simple answer is yes. “Because they use a reduced volume of water and may apply less pressure than a regular toilet, low-flow toilets do not always flush waste as well as their standard counterparts.” Sometimes you will need to flush 2-3 times to clear the waste completely. This is not common, but it is worth mentioning. The benefits of low flow toilets far outweigh the occasional clog.
