Rainwood draws on the grain, knots and tonal variation of oak across a 15x90cm plank format. The longer plank gives the surface detail space to play out, and with tonal shifts and natural markings moving across each tile, walls and floors take on a wood character that builds naturally across the surface. Two colours give the range a breadth that suits different palettes, both in a matt porcelain finish with rectified edges. A minimum 3mm grout joint is recommended and a 10mm trim is required for installation.
