Portland Grey 400x300mm

Each Portland Grey 400x300mm sheet covers 0.12m², and you will need 9 sheets per square metre. To calculate how many sheets to order, measure your wall area in square metres and multiply by 9, then add around 10% extra to account for cuts and wastage. Since each sheet is sold individually, it is straightforward to order precisely the quantity you need.

The Portland Grey sheet measures 400x300mm overall, but the individual mosaic pieces within each sheet measure either 300x23mm or 300x48mm, giving the design its distinctive linear, modern appearance. This mix of strip sizes creates a layered, textural effect that works particularly well as a feature wall or splashback in bathrooms and kitchens. The mesh backing holds all pieces in place, so you tile the whole sheet at once rather than placing individual pieces by hand.

Yes, the Portland Grey is rated for wall use in both bathrooms and kitchens, making it a practical choice for shower walls and wet areas. Its glass and metal construction with a glossy finish is easy to wipe clean and resists moisture effectively. Do bear in mind this tile is not rated for floor use, so it should be kept to wall applications only, including shower enclosures and splashbacks.
