What's The Best Niagara Toilet?
Review & Buyer's Guide In 2020

Well, well, well, look what we have here! Niagara Conservation. The most recent trend circulating through most bathroom ware companies (See other toilet brands here) is definitely the environmental-friendly craze. And I think it’s safe to say Niagara takes water saving to a whole new level. However, the only question is, can Niagara beat TOTO in terms of achieving the spotless white throne?

Can any toilet company beats the king on the hill, TOTO? Can Niagara be the Mike Tyson in toilet world? Well, it seems that the Niagara Stealth series are the most water-conservative toilets that I’ve ever seen. It seems that Niagara may be worth giving a shot after all!

From the outside, Niagara Stealth looks like any other toilet, nothing special. Perhaps except for the double trapway that makes siphon works better. Well, as it turn out, you can’t judge a toilet by its white finish.

This water closet uses only 0.8 gallon of water when flushing. Considering most of the commodes on the market use 1.0 GPF or higher, this is a buried treasure.

The secret behind this toilet is that it is not a gravity toilet. Instead, it is pressure-assist, which means it can use less water to achieve the same result. One of the huge downsides of pressure assist toilets though, is that it makes a loud jet engine sound when triggering the valve. However, Niagara invented the noise cancelling tank to eliminate the problem. Well, the toilet is called “Stealth” after all!

The model’s dimensions are 28.9 x 18.8 x 31 inches and weighs 103 pounds, pretty standard stuff. The only drawback is when buying from Amazon, it doesn’t come with a seat and wax ring...but if you get it elsewhere, it should be fine. Finally, it’s important to note that this toilet is labeled as WaterSense.

What We Don't Like:

  • Clogging can be an occasional issue
  • exclamation-triangle
    You may have to purchase a wax ring and seat separately.


  • Pantended hydraulic technology - Different from other pressure assist systems, Niagara adopts the vacuum effect to pull water from the water chamber instead of applying pressure from the cistern. By doing so, the system depressurizes the trapway and tranquilizes the jet engine sound, which is the typical background noise for pressure assist models.
  • Air Transfer Tube - This little thing creates the vacuum effect in the cistern. When the tank is filling water, the air is pushed back to this tube. The system later uses the air to pressurize the flush.

Inside The Bowl

  • No Flapper - Niagara’s toilets use a different way to refill the water tank and most of the models are pressure assist, the structure inside the cistern is not surprisingly distinguished from traditional gravity toilets. So instead of having a wax-ring like seal, Niagara chooses to use a hard plastic plate. By doing so, the pressure is able to distribute equally around the tank.
  • Rim Holes and Siphon Jet - In order to efficiently use water during flushing. Niagara improves the traditional toilet design with Rim Holes and Siphon Jet. Several small Rim Holes are located equally around the rim of the toilet seat, which cleanse the remaining area from the main flush. Another feature is Siphon Jet- connecting the bowl and the water pipe. It is made smaller to enhance the siphon effect.

Apparently, Niagara is very proud of their water-saving abilities. In fact, the whole brand is built around the concept. In the 1970s, Bill Cutler, the founder, invented a shower head, because he thought saving water was a cool thing to do. Soon after, the conservative shower head became a hit in the era, which lead to the birth of Niagara.

But Bill didn’t stop there. There was a fire inside of him that kept pushing him forward. In 2000, Niagara came up with a super efficient toilet that was never seen before. A toilet that used only 0.8 gallons when flushing. Sure enough, this breathtaking lavatory earned the one and only UHET (Ultra High Efficiency Toilet) label.

I was wrong.

Niagara is not only an exciting company, but a burning star. I can almost predict that in the future Niagara will shine brighter than TOTO if the company keeps producing great products. Anyway, you should not miss this model if saving money on water bill is your goal.

Be clean. Stay white. Good luck.
