Porcelanosa Japan Marine 20×31.6cm

Yes, the Japan Marine 20×31.6cm is a ceramic wall tile designed specifically for bathroom use, making it well suited for wet areas such as shower enclosures and bath surrounds. Its matt finish gives it a practical, low-sheen surface that works beautifully in moisture-rich environments. Just ensure the substrate is properly waterproofed before installation, as is standard practice for any wet-room wall application.

Each box of the Japan Marine 20×31.6cm contains 20 tiles and covers 1.264m², so you simply need to calculate the area of your splashback in square metres and divide by 1.264 to find the number of boxes required. For example, a splashback measuring 0.6m x 1.5m (0.9m²) would need just one box, with tiles to spare. We always recommend ordering around 10% extra to account for cuts and any future repairs.

Yes, the Japan Marine tile is listed as suitable for underfloor heating, so if you are fitting a heated wall panel system or have underfloor heating running beneath an adjacent tiled area, these tiles will perform well. However, please note they are rated for wall use only and should not be laid on a floor regardless of heating compatibility. Always follow your underfloor heating manufacturer’s guidelines regarding tile adhesive and grout selection when working in heated environments.
