Question: Would you recommend the Niagara Stealth Toilet for a restaurant application where there will be high traffic, heavy use? I need a 0.8 gpf toilet for a Platinum LEED project.but I’m worried about it’s ability to hold up over time. Thanks!

Answer: The Stealth Toilet from Niagara Conservation is an ultra high efficiency toilet that only uses 0.8 gallons of water per flush (gpf). The toilet uses hydraulic technology to keep the flush quiet – hence the name “Stealth.”

Niagara Stealth Toilet for LEED

Due to it’s water saving technology, the Stealth toilet can contribute to a LEED project in the Water Efficiency credit category.

According to LEED v4, the Stealth could contribute to the following credits:

Water Efficiency (WE) Prerequisite 1, Indoor Water Use Reduction (0 points):

This credit requires that the building uses 20% less water than the baseline. Since LEED’s baseline for toilets is 1.6 gpf, the Stealth’s 0.8 gpf exceeds the 20% reduction requirement.

Water Efficiency (WE) Credit 3, Indoor Water Use Reduction (up to 6 points):

This credit is the same as Prerequisite 1, except it awards points for greater levels of water reduction. It awards 1 point for 35% water reduction to 6 points for 50%. Niagara’s Stealth toilet is are 50% more efficient than the 1.6 gpf baseline, so it can contribute to this credit.

Niagara Stealth Toilet for Commercial Use: Reviews and Warranty

I have never used the Stealth Toilet, but from my research, it seems that it would hold up in your restaurant (or in other commercial applications).resteraunt

I called Niagara Conservation, and the representative said that the Stealth can be used in commercial applications, such as restaurants. It will still have a 10-year limited warranty, even if used commercially – so even if the toilet does not hold up with the heavy use, you will be eligible for replacement parts for 10 years.

Additionally, the toilet seems to have a high satisfaction rate.

According to Conservation Warehouse International, 92% were satisfied with and would recommend the toilet. Seventy-two percent said that the toilet clogged less often than their old toilet.

Also, I’d recommend reading reviews from consumers. For example, Amazon shows a positive customer review for the toilet, which says that the toilet does not clog often.

I hope this helps!
