A classic, high-performance design for modern commercial restrooms, Zurn's Z5571 high-efficiency two-piece toilet is a perfect blend of style and function. With its chloramine-resistant internal components and high-gloss vitreous china finish, it's stain-resistant, sanitary and durable inside and out. It features a water-conserving 1.1 GPF, saving both water and money. A pressure-assisted tank and siphon-jet action yield a powerful flush while our EcoFlush technology makes it an ultra-quiet one. The Z5571 is standard height and has an elongated rim. Add an oblong toilet seat (Z5958SS-EL), bolt and wax ring (Z5972-COMB) and standard stop with riser (Z8800-CR) for a complete setup. Zurn two-piece toilets offer a simple, durable solution for new or retrofit commercial bathroom projects.

Great toilet. I have had one installed for over 2 years now with pressure-assisted flush tank. The high-gloss china is not only easy to clean, but it seems to resist staining. Only downside is that the basin is a bit wobbly without a Secure-a-Tank bracket but those are only 4.99.

Giving 4/5 principally because although the flushing mechanism is extremely good, if buying this , the purchaser should be aware that it is more noisy than the average toilet. Thus, if installed in a family home it could disturb sleeping children .
Hope that helps?

Installation went well. Had a little trouble getting the tank to seal onto the bowl base, but once seated properly, it was fine. Powerful flush, which I love. Though it is likely to startle guests in a residential environment. Overall build quality seems good, power-assisted flush mechanism, not made by Zurn, looks solid and so far performs as such. A little disconcerting that the manual expends more paper on replacing the flush mechanism than anything else. But overall I really love my Zurn Eco Vantage. Is that weird?

Very nice replacement for 18 year old commercial toilet. Noisy, but not as bad as I expected. Very efficient flushing, no complaints so far. Have had several comments (but not complaints) that seat is a little low, definitely a little shorter than the model it replaced. May be an issue for some. Isn't for us.

LOVE this toilet. It does exactly what we bought it for. We needed it to have a GREAT flush effort and it does. We needed powerful and it is. We only put it in a week ago but it stands up to our expectations. It is used in our basement with cement floors and the other toilet just couldn't handle the flushing action. We used to have to flush 2 or 3 times to empty the toilet.
