It has an advantage over Redgard in steam showers as it is a vapor barrier whereas Redgard is not.#N#Like I said, if you're not happy with Kerdi there are other options that will work well if properly installed to mfg specs.#N#My biggest gripe with Kerdi is that overlapped seams can build out to the point of causing setting problems, particularly in the inside corners of niches.
