Why the Stealth Toilet with its .8 Gallon per Flush Stole My Heart

Stealth .8 gallon per flush Toilet

Looking for a stylish, uber water conservation toilet where poop has met its match?   The green status symbol toilet?  One that even Ed Begley,  Jr. would be proud to park his rump on? Welcome Niagara Conservation’s Stealth, the first to the market .8 gallon per flush toilet.  Yep.  You heard me right.  This clever toilet uses only .8 gallons per flush.  HALF of the federal standard of 1.6 gallon per flush.

Was I excited about this toilet?  You betcha.  You all know I am a girl who loves poop talk.  In the past, I have spoken about different recycled toilet papers, a  no-mix toilet that uses the urine as fertilizer, and even spent an hour on a podcast with American Standard about their new conservations measures. Yes, I am one happy girl when you mention green toilets.  (Come on.  I know lots of you can relate. No?  Different strokes for different folks.)

Why the Stealth Toilet Stole My Heart.

Anna, there is no way this .8 gallon toilet is going to flush the dirty dozen, poop, #2, or whatever name you use for the brown stuff.

Ladies and Gentlemen, I saw it myself.  With my own eyes.  During my interview with Cecelia Hayward, the Market Manager at Niagara Conservation, I filmed how this toilet flushes.  Yep.  Captured the whole dirty deed on the below video.  Look what I am willing to do to get to the bottom of the bowl for you.  (Complete with comedic review. Poop is still funny.  And yes, we never grow up.)

The Details are in the Flush.

How the Stealth High Efficiency Toilet Flushes

Okay. I was a naysayer until I saw the toilet in action.  This is one impressive toilet.  But I was a little confused on how this toilet could use such little water.  The Company states,

“[w]ith its low-profile body, breakthrough patented hydraulic technology, and the quietest flush on the planet, the unique design of the Stealth™ toilet has revolutionized the market and set a new standard for manufacturers around the world. By harnessing the energy created by water filling the tank, this toilet uses a patented air transfer system to pressurize the trapway within the bowl. Pressing the flush button activates the swift, powerful and quiet flush that fully evacuates all waste in the bowl. The Stealth toilet is available in both round front and elongated models to fit a standard 12” rough-in installation. The Stealth™ toilet easily replaces your existing toilet, lowering water usage and utility bills like no other toilet can.”

Other attributes according to the Company:

My thoughts on its flush.  Kevin from Niagara put in 7 wads of paper and 18 fake poop pellets.  It flushes them all except one.  Realize if this toilet didn’t perform well, it would never have received the EPA label.  So, I still was pretty impressed.  (Plumbers, watch the video and you tell me what you think.)

How Much Is this Water Conservation Toilet Going to Save Me?

According to the Company, it should save you 20,000 gallons a year or about $101 a year depending on the cost of your water and utility costs.  (Note, this figure is based upon comparing a 3.5 gallon per flush toilet to the Stealth .8 gallons per flush with 4 people/5 flushes per day.)

I can’t verify the Company’s numbers, but I plugged in similar numbers on the American Standard’s calculator. This calculator only allowed me to plug in a 3.5 gallons per flush toilet and compare it to a 1.1 gallon per flush toilet.  The data was as follows:

3.5 gallon to 1.1 gallon toilet saves 4380 gallons of water per year based on 5 gallons of water, and $27 in yearly savings based upon .06  per 1000 gallons of water.  Note, this doesn’t take into account sewer charges.

So, I am not sure where the Company derived its 20,000 gallons savings.   However,  when I extrapolate the above number based upon a 3.5 gallon to a .8 gallon per flush, it would seem that the toilet would save 5694 gallons and save $35 per year.  Remember, sewer savings is not included.

Of course going from a 1.6 gallon to a .8 gallon would yield smaller savings.  Everyone, you are welcomed to jump right in and tell me if I did the math correctly.

In any event, this toilet is worth exploring if you are retrofitting or buying new for both residential or commercial.  If you do buy, make sure when you entertain that you point out your newest green member to your family.  Talk about keeping up with the Jones.

  • What do you think of this toilet?
  • Do my numbers look right?
  • Would you swap out your 1.6 gallons per flush toilet at this time?
  • Would you spend $300 for this toilet?
  • Does it matter to you if the flusher is on the top of the toilet? (You couldn’t use the top of your toilet as a shelf.)

    We purchased and installed the Glacier Bay UHET toilet last week in our home. So far no issues at all with the flushing power of the toilet. It is very quiet, and does the job it was designed to do. The price for the Glacier Bay at Home Depot is much less than the cost of the Niagra, but not quite as attractive looking tank as the Niagra. Overall we are very impressed with the performance of this toilet so far. If you live in an area with high water costs or are just concerned about the planet this is a good investment and I am glad we decided to make this change.

    Great article. My landlord installed this in my apartment and it is great.

    I am curious about any added maintenance costs or plumbing issues it may cause just so I know all the facts about it.

    I purchased the Glacier Bay version from Home Depot and it has consistently leaked and refilled from day one. I initially thought it was part of the pressure mechanism so I didn’t really look at it. Well, thousands of gallons of wasted water later, I find out it has been leaking and refilling every 10 minutes for close to a year. I take responsibility for not knowing enough about toilets to recognize this as a problem sooner(the water is now off). However, HomeDepot has quit selling them and no one remembers that they once did so can’t help me try to find the problem. Also, Niagara won’t call me back. I really want this .8 gpf toilet to work as I have never had any issues with flushing solids including wads of TP because we don’t flush every time we urinate.

    Let me know if anyone has any ideas.

    I had a .8 niagra toilet installed by a company by the name of Restored Resources (by a woman none the less) and it is AMAZING!! I can see the savings in my home of 3! The shower heads and faucet thingys were changed too. Awesome company and awesome product!

    Another toilet to consider is from Mansfield. They make most of their toilets in Ohio, which is kinda cool. They have one called the Maverick that uses only 1.0 gallon, which is only a little more than the Niagara. So far it flushes great.

    I was really looking forward to replacing a very old toilet with this one. I ordered one through Amazon. The first attempt resulted in chipped porcelain at the back of the bowl. The packaging was just fine with no damage to the inner or outer shipping box. I actually could have lived with the chip being that it was at the very back and would never have been seen after installation. The bigger problem with this one and the next two replacement bowls that were shipped were show stoppers. All three had the same issue where the porcelain did not completely cover the ceramic base of the bowls. Obviously they were never inspected or they would never have shipped. To get three in a row like this says a lot about quality control.

    Unfortunately after three attempts I just returned everything for a refund. Needless to say I am extremely disappointed.
