Is your toilet a water guzzler? According to the US Environmental Protection Agency, replacing your old regular toilet with a low-flow water-saving toilet can save up to 13,000 gallons of water annually – saving around $140/year or $2,900 over the lifetime of the toilet.
By installing a low-flow toilet in your bathroom or upgrading your regular toilet, you can save water and help the environment.
In this post, I’m going to tell you how you can retrofit your existing toilet to save water and money. Then I’ll tell you about the best water-saving toilets on the market, including the best water-saving smart toilets, the best for small bathrooms, the cheapest water-saving toilets, the best looking ones, and more!
Why Is a Water Saving Toilet Good To Have?
According to the United States Environmental Protection Agency (EPA), water usage in toilets accounts for 30% of the indoor water consumption for an average household, with some toilets using 6 gallons per flush.
This means that your household could be flushing good clean water down the drain while costing you a fortune!
To combat this reckless waste of water, the EPA has introduced the WaterSense label for toilets that have been certified to meet specific criteria to save water. These high-performance toilets are water-efficient, using only 1.28 gallons per flush – or less.( Source)
Upgrading to a water-saving toilet could save your household 4,000 gallons of water annually! Watch the excellent video above from www.FusionNW.com for more info on just how much water you can save.
The Benefits of Water Saving Toilets
Water-saving toilets are designed to save water with every flush. Regular toilets are called full-flush as they empty the bowl of water with every flush.
Low-flow or low-flush toilets are designed to use much less water while performing the same function – hygienically removing the contents of the toilet bowl without any fuss. A single flush from a low-flow toilet uses 1.28 GPF compared to the 6 GPF used by a regular toilet.
High-efficiency (HET) or ultra-high efficiency (UHET) toilets are energy-efficient low-flow toilets that are designed to use the least amount of water in the most effective way possible.
These toilets use 0.8 to 1.1 GPF (Gallons per flush) to remove waste, effectively using water velocity instead of water volume.
If you install one of these water-saving toilets, you could qualify for a rebate from your water provider or local municipality – a great way to keep your cash in your pocket while helping the environment. (Source)

Advantages of Water-Saving Toilets
- Low-flow toilets use less water, so they are good for the environment.
- Toilets that use less water result in savings on your utility bills.
- A dual-flush option offers you a choice of 2 different settings using more or less water.
- Low-flush toilets are easy to use and easy to clean.
- Low-flush toilets add value to your home, making it more attractive to potential buyers.
Disadvantages of Water-Saving Toilets
- Water-saving toilets can be a bit more pricey than regular toilets
- The installation could cost more as most water-saving toilets should be installed by a professional.
- Low-flow toilets are prone to clogging due to the low water pressure.
- Older models might not be as effective and could leak.
What to Look for When Choosing a Water Saving Toilet
If you’re thinking of replacing your old-fashioned, regular toilet, you have two options:
- Upgrade to a newer model
- Replace the current flushing mechanism in your regular toilet
Why Retrofit Your Toilet?
Unless your toilet bowl is cracked or the toilet is really old and outdated, you should consider upgrading or retrofitting your toilet.
Replacing your not-so-old toilet with a newer model would likely mean that your old toilet would end up in a landfill somewhere while retrofitting it could be more economically viable and eco-friendly!
The below table lists the different types of low-flow toilets and how they work:
|TYPE OF TOILET||HOW IT WORKS|
|Gravity-Assisted||Water flows down from the cistern into the toilet bowl and washes away the waste|
|Dual-Flush||Full flush or partial flush levers. A 1.6 gallon flush for solid waste and 0.8 to 1.1-gallon flush for liquid waste|
|Pressure- Assisted||Water fills the tank and compresses the air inside, creating pressure. When flushed, the water is forced into the bowl, washing away the waste.|
|Vacuum-Assisted||Waste is powerfully sucked out of the bottom of the toilet through the trapway.|
|Tank inserts||Placed inside the tank, reducing the water usage by 0.5 to 1 gallon per flush|
If you’re seriously considering a bathroom remodel and would love a new, eco-friendly, and more sustainable toilet, these are the features you should consider before you buy:
Consider the size, space, and color scheme of your existing bathroom. Measure the available space before you buy your new toilet to make sure that the model you like will, in fact, fit the space.
If you love the idea of a wall-mounted toilet, check that the walls can carry the weight. Taller toilets have a more powerful flush as the water has further to fall. Round bowls will clear easier than elongated bowls.
Set a budget to match your needs before deciding on what to buy.
Two-piece toilets are generally cheaper than a one-piece. However, a more expensive toilet does not necessarily mean better quality than a more affordable model.
Also, if you are planning to move the plumbing wall in your bathroom to a new location, be prepared to incur considerable expense.
2. Water Consumption Certification
Always look for the WaterSense label on the toilet.
The WaterSense label ensures that the toilet is low-flow and has been approved by the EPA as an environmentally friendly, high-efficiency toilet, using not more than 1.28 GPF.
3. Waste Removal And Water Usage
It’s essential to consider the different flush types when choosing a low-flow toilet. A “full-flush” system will use much more water than a “partial-flush” system to remove waste.
A “dual-flush” toilet allows you to use more or less water as the need arises, while a “single-flush” system using the “tornado flush” is more economical.
The tornado flush system propels water into the toilet bowl from jets located around the rim of the bowl. This powerful spray of water creates a whirlpool effect, swirling the water around the bowl to clean off all the debris.
This system is one of the quietest flushing mechanisms as gravity is used to move the water around the bowl, reducing the pressure and the noise.
“High-efficiency” models offer the most potent flush using the least amount of water.
4. The Noise!
Toilets make funny noises! Gushing, flushing, and gurgling sounds can be a thing of the past with water-wise toilets.
Water-wise toilets are quieter than regular toilets as they use less water in the cistern.
