I am trying to find a comfort height toilet that meets water sense standards AND is within our price point. bear in mind that we are in the Canadian market so availability of some makes and models is a factor too. I have found the Verrazano Tall Boy at 18", but cannot find a review of it, nor any discussions about it. I find it's absence on the web a little scary. To add to my concerns, it features only a two year limited guarantee. Anybody out there have any experience with this particular make and model?
