ETA: I've received LOTS of concern about how sanitary this application would be behind a toilet. Its not for everyone. Its just the two of us in our home and neither one of us is a messy bathroom goer, so we have zero problems with it. I just use my vacuum hose to "dust" it occasionally. :)
ETA: This application IS NOT for high humidity spaces. I recommend using a wood look tile for those areas.
