Porcelanosa Magma Black 33.3x100cm

The Magma Black features a sophisticated stone effect matt finish and rectified edges, which allow for very tight, consistent grout lines that enhance the natural stone appearance across a large surface. It is suitable for bathrooms, kitchens, hallways, bedrooms, and living rooms, making it an excellent choice wherever a bold, dramatic feature wall is desired. The large 33.3×100 cm format means fewer grout joints, giving the finished wall a sleek, seamless look.

Each box of Magma Black contains 5 tiles and covers 1.67 m², with 3 tiles required per square metre. To calculate your order, measure the total wall area you intend to tile in square metres, add at least 10% to account for cuts and wastage, then divide the total by 1.67 and round up to the nearest whole box. Because the tiles are large and dark, precise cutting is important, so a slightly more generous wastage allowance is advisable.

Yes, rectified tiles have been precision-cut after firing to ensure perfectly straight, uniform edges, which is particularly beneficial with a large-format tile like this 33.3×100 cm design. This allows for very narrow grout joints, typically 1.5-2 mm, which reinforces the stone-effect aesthetic and gives the wall a more continuous, uninterrupted finish. It is important to use a suitable tile adhesive and follow the manufacturer’s guidelines, as rectified tiles require a flatter substrate than non-rectified tiles due to the reduced grout joint tolerance.
