Niagara is a name that you might not have heard of easily in most debates of the best toilet brands. But this is changing quite fast.

With the increased demand for the most water efficient toilet systems, Niagara seems to have carved out a competitive space for itself with its ultra-high Efficient Toilets.

An Ultra High Efficient Toilet refers to a system that goes way beyond WaterSense stringent water-saving requirements of 1.28 gallons. Niagara does this effortless by designing commodes that use 0.8 gallons per flush.

Mind you, Niagara is the only brand that offers the U-HET at the moment. These frugal toilets may be ideal for people who live in drought-stricken areas and those who want to cut their water bills even further.

1. Niagara 77001WHCO1 Stealth – Editor’s Choice

Low Water Consumption

The Niagara 7700WHCO1 seems pretty basic from a glance. Its white color and smooth shiny surface, however, make it a great choice for the average joe.

Niagara 77001WHCO1 StealthThis is a 2 piece model. So, it might ship in 2 boxes. Its installation process might also be easier because you’ll be dealing with a one part at a time.
How does it perform?

0.8 GPF Flush Rate

This toilet is among the only 2 models that offer a 0.8 GPF flush rate on the market today. This means that you might experience a significant drop in your water bills once you get it running because it uses way less water than most traditional toilets.

WaterSense Certified

Its low water consumption makes it WaterSense certified and may qualify you for rebates, that is, if your water provider offers these incentives (find out in Rebate Finder).

But what’s so intriguing is its excellent waste evacuation ability even with its amazingly low water consumption. This may be attributed to its pressure-assist flushing system and nicely glossed interiors and trapyway.

On this note too, most homeowners report that this toilet has very quiet flushes. This makes it a good contender if your bathroom has thin walls and close to your bedroom.

Comfortable and Spacious

Well, if you find an elongated bowl quite comfortable and spacious for your business, then this toilet will fit your description for a comfortable toilet.

You might also like that it is partly ADA-compliant thanks to its comfort height. Note that for a commode to qualify to be ADA-compliant it should have a flush lever, not a button as it’s the case with the Niagara 77001WHCO1 Stealth.

2. Niagara N7711 Stealth – Premium Pick

One Piece Design

Niagara N7711 Stealth

Our next model here sits rightfully between the 77001WHCO1 Stealth and the 22003WHCO1 EcoLogic. It is an advanced version that seems to bring you all the nice features from our first 2 recommendations but at a slightly higher price tag. Is it worth its cost?

The most outstanding feature of the Niagara N7711 Stealth is its one piece design. Unlike with its siblings, you are guaranteed that this model will ship in one package and at the same day. So, if you are planning to take the day off to install it, this one might be quite convenient.

Low Profile Design

Its one piece design also gives your small bath an illusion of space due to its low profile design. It might also be a little bit easier to clean because it does not have a crevice between its tank and bowl.

Speaking of cleaning, this toilet has an all around skirting. This blocky, seamless design not only adds to its stylish design but also hides nooks and hard-to-reach areas that might trap dust and dirt.

Flapperless System

The Niagara N7711 might also save you lots of water thanks to its ultra-high efficiency. This toilet uses a flapperless system that features a patented flush chamber and an air transfer system.

It delivers powerful 0.8 gallon flushes that combine with the bowl’s smooth, low friction ceramic surfaces to offer one flush waste elimination and excellent bowl-cleaning performances every time.

This toilet has an elongated bowl for added comfort and a ‘comfort height’ to make it friendlier to a wide range of users. It is also amazingly quiet thanks to its flapperless design.

3. Niagara 22003WHCO1 EcoLogic – Budget Buy

NO Refilling Noise

Niagara 22003WHCO1 EcoLogic

The Niagara 22003WHCO1 is another option from Niagara’s other line of toilets, Ecologic. As you’ll soon find out, this one is no match for the 77001WHCO1 Stealth above in terms of water conservancy.

But it’s still a good water saver and has lots of other terrific benefits that make it worth going for.

2 Piece Toilet

Similar to its sibling, the Ecologic is a 2 piece toilet. The manufacturer states that it might come in 2 separate boxes and on different dates. This is the main disadvantage with 2-piece toilets.

Low Cost Toilet

The most notable feature here is that it is fully ADA-compliant. This toilet comes with the comfort height which may be a lifesaving feature for many. Its flushing mechanism, on the other hand, is triggered via a trip lever at the right side of the tank.

The Ecologic has a round-front bowl. This bowl design may allow you to install the commode in tight areas where the Stealth’s elongated bowl may not leave you enough legroom.

1.6 Gallons Per Flush

Previous homeowners’ responses also affirm that this toilet has a reliable flushing performance. This toilet uses 1.6 gallons per flush which, albeit not WaterSense-certified, could save you upwards of 10,000 gallons of water per year.

Flapperless System Design

The good news with the 22003WHCO1 EcoLogic is that it has been designed to eliminate all refilling noise. This toilet uses Niagara’s flapperless system design. This is basically a trough that will dump over once you pull the lever handle.

Among other benefits, you’ll never have to struggle with a stuck flapper. This technically eliminates the risk of floods on your bathroom floors.
What’s more, this ingenious design exempts you from the need to replace a worn out flush valve. Several buyers also report that they no longer have issues with a sweating tank anymore.

Editor’s Choice

Niagara 77001WHCO1 Stealth

Overall, the Niagara 77001WHCO1 Stealth is a highly recommendable option if you are looking for a tow piece toilet that will help you save on your water bills.

It’s at a good price (compared to its siblings) and we like that it brings all the nice features that a comfortable and reliable toilet should have, in our opinion.

It has an elongated bowl, stylish design, and a flushing system that does it’s job. Importantly, this is an ultra efficient toilet, it only uses 0.8 GPF and also has an extremely quiet flush.

With their excellent water efficiency and great flushing designs, the Niagara toilets are, hands down, the way to go, especially if you have a busy bathroom.

One thing that clearly gives them the upper hand is their flapperless design. No one really wants to keep fiddling with a flush valve that won’t do its work. The flapperless flushing system also eliminates almost all the filling noise – a problem that plagues most of the high-end commodes today.
