One of the “Must-See” products of the recent Kitchen and Bath Industry Show was this wall-hung tank and carrier system from Geberit called the Monolith.  Monolith installs in construction or a renovation (if you’re interested in moving the sewer to the wall) and saves bathroom space by tucking the tank and valves behind glass.  The product comes with a couple water-efficient flush options and black or white glass, though I can’t seem to locate Monolith anywhere on the Geberit US website.  Keep your eyes open for availability.
