Geberit has updated its Sigma 2×4 in-wall concealed tank and carrier system for wall-hung toilets to fit a standard 2×6 frame, which the manufacturer says will make it easier to prep walls during installation. The new tank allows more space for removal and replacement of fill and flush valves, without tools. The single-piece system has L-supports for added stability for long or narrow bowls, and adjustable legs to accommodate floor construction up to 8 inches. The system retails for $650. geberitnorthamerica.com
