A repeating modular pattern made up of at least three different tile sizes in order to give a random effect to the floor. There are various Opus patterns available in specific products. Please note you cannot choose a material to come in a particular Opus, the material will come in the Opus stated. Please see individual product pages and Stone Layouts. NB. Where a product is available in an Opus pattern, tiles are sold to the nearest full module but priced per m².
