About This Product

This 2-piece 0.8 GPF Ultra-High-Efficiency Single Flush Elongated Toilet featuring Stealth Technology in White from Niagara is the world's first ultra-high-efficiency toilet. Powering the toilet is Stealth, patented vacuum-assist technology from Niagara, which uses only 0.8 GPF (3 LPF) while still providing a powerful flush that thoroughly evacuates the bowl every time, no need to double flush. The flapper-less design eliminates chains and levers, making maintenance and leaks a thing of the past. Also, this toilet virtually eliminates all refill noise as the fill valve is never exposed. Niagara toilets deliver a quiet, powerful and proven flush, saving thousands of gallons of water with no change in consumer use or behavior.

    Answer This Question

    Hi Roddy, thank you for your interest in our ultra-high-efficiency toilet! The seat height for this Stealth model is 17 inches from the floor to the top of the bowl, which provides an ADA approved height that many users find much easier to sit down on and stand up from.

            Answer This Question

                Is a 13-in rough-in from the wall to the bolt usable?
                ByJun 18, 2025
                1 Answer | 
                Answer This Question

                Hello Peter, If the rough-in space is 13-in, after installation there should be a little over an inch gap between the wall and the back of the tank. Should you have further comments or need future assistance, please call 1-855-434-5224 and one of our team members would be happy to help you.

                  Bad Flush - Multiple times
                  I have installed this for my half bath downstairs and have noticed that the flushing isn’t good. We have to flush atleast 3 times though water usage is less but 3 flushes is quite more than any Regular 1.6GPF. I heard a lot of mixed reviews but went ahead with it. I am not sure if it’s setting and got it checked with my plumber but he says all good.

                  Hi Chai, we are truly sorry to hear that your new toilet isn't providing the powerful one-flush performance you expected, especially after having a professional plumber take a look. Please call our customer support team at 800-831-8383 or email us at info@niagaracorp.com so we can help to troubleshoot this toilet.
                    Not the first time purchasing the Niagara Stealth Stealth toilets. Installed 3 of them in the past at a rental property because of their water consumption. Water bill the following period went down dramatically. I recently ordered several more to upgrade a family members house and to also help reduce their water bill. Worked as planned once again on their following bill. I highly recommend this product if you are looking for a decent toilet that can help reduce the cost of water usage. In the rental property, they have already stood the test of time since 2018 (original purchase), especially when it comes to tenants.

                    Worst Toilets Ever!
                    I have had so many issues with these toilets. I bought 3 at home depot. First major problem, when these toilets go down, you cannot pick up parts locally. You have to wait for the part to come in the mail directly from the company. Most plumbers will not carry these parts either. I had two handyman and plumber to come out to repair and we did all the troubleshooting steps sent by Niagara and the issues were not corrected. All repair techs said it is an issue with the design of the toilet. I have spent so much money on labor and months without the proper use of two toilets. One where it flushed every other time and the other running for almost 4 minutes after the toilet flushed. The bowl water height level is an issue. No matter how many adjustments, it just does not fill the bowl to the correct water level. Save yourself the trouble and hassle and choose another toilet!

                    Hi 727Lt, thank you for taking the time to provide this detailed feedback, and we sincerely apologize for the deeply frustrating experience you have had with all three of your toilets. It is unacceptable that you have spent so much on labor and gone months without the proper function of your toilets, and we regret that troubleshooting with Niagara and multiple professionals did not resolve the problems with the inconsistent flushing, continuous running, and low bowl water level. We want to work with you immediately to find a complete and lasting solution for all three units, as this is not the experience we intend for our customers, so please contact our dedicated customer support team right away at 800-831-8383 or via email at info@niagaracorp.com so we can provide the necessary support.

                      Hi there, thank you for your review. We're very sorry to hear that your toilet is constantly running—especially with such frequency. That kind of issue can definitely be frustrating, and it’s not the experience we want for our customers.
                      This may be caused by a flush valve seal that isn’t closing completely or a chain that’s too tight. You can try:
                      Clearing any debris from the flush valve seal and its seating area.
                      Adjusting the chain length so there’s a small amount of slack, allowing the seal to fully close.
                      If the issue continues, we’d like to help troubleshoot further. Please reach out to our customer support team at 1-855-434-5224 so we can assist you directly. We're here to help make this right.

                        Nice toilet would buy again
                        I never heard of this brand, so was hesitant. The quality was very good all parts were included even a wax ring. Strangely you don’t need to run a little hose from the fill valve to the flush mechanism. The flush is powerful and I like the .8 gallons per. I’d buy again. As a bonus my water utility rebates about 3/4 of the purchase price because this is WaterWise certified

                          Not flush well
                          I was attracted by its "0.8 GPF" feature, and it turned out it is lack of basic feature as a toilet. First, it does not flush well, as shown in attached video. When it must be flushed multiple times, it uses more water instead of 0.8 gal. When I contacted their support team, they claimed it was installed correctly which I don't believe it is true. Secondly, this Niagara Stealth toilet is higher than regular ones, which makes it is quite uncomfortable to sit on it. It picture you may notice it is over 17 inch.

                            Best toilet I have seen.
                            This is the second one I bought and would buy again. Not a big fan of Made in Ghina, when this engineered in USA but is produced there, especially when there are USA made units available like Mansfield and some Kohler but the conservation is the reason I bought it and price , install and functionality is great as well. Comes with everything to hook up to your valve hose. Best less water usage but if you are big plus size the seat and discharge might not do it for you. Earth savers take a look.

                              Most over-engineered toilet valve ever ... malfunctions often.
                              The flap-less valve mechanism on this toilet is over-engineered to the point of malfunctioning. I've replaced the valve FOUR (4) times because it always begins to "run" after a year or so and won't completely shut off the water flow. Waste of time and money. I really have to wonder whether the people who own Niagara actually use their own toilets, or do they buy a better brand -- one that works -- for their own homes? AVOID!!!

                                We had been talking about purchasing a high toilet. I love this toilet the pricing is affordable. My husband had no problems with installation. The only issue I have and the reason for only 4 stars is the seat slides to the left. My husband has tried numerous times to adjust but it keeps sliding to the left. Never experienced this with any other toilet seat. I'm wondering if I purchase another seat will I have the same problem?
