Glass basins and worktops lacquered on the underside. They are made in special crystal clear glass, which is a more neutral colour than ordinary float glass because it contains less iron oxide. The basins are easy to clean and the surface is resistant to normal chemicals. NB: The thin design requires support from cabinets across the full width. However, the basin or worktop is strong enough for an overhang up to 100 mm without support. The basin waste must not be over-tightened. Do NOT use tools for tightening.
