There's probably a few contenders for this claim but most of them have price tickets of over $1000 and sometimes more. For example, our $349 premium toilet suite can be found for $2000 with a different name on the box.
At ISWG, we searched and researched for the absolute highest quality Watermark toilet set we could find ... and we are selling it for less than a quarter of the price you might see it sold elsewhere.
