The River Anthracite 20mm outdoor porcelain tile combines a deep anthracite shade with a strong slate-inspired appearance with a substantial 20 mm porcelain body. It is designed for bold contemporary patios, outdoor kitchens, modern extensions and sharply landscaped garden zones, giving the finished area a considered, durable and premium appearance.
The dark surface creates immediate contrast and gives pale walls, timber details and planting a sharper visual impact. The 600 × 900 mm format also helps create a calmer layout with fewer visual interruptions than smaller paving.
This tile gives you the appearance of carefully selected outdoor paving with the consistency of porcelain. Its colour works with real homes and gardens, while the format gives the floor a premium sense of scale. It is a strong choice when the paving needs to look smart without becoming difficult to coordinate with furniture, walls and planting.
The Anthracite colouring works especially well with white render, pale masonry, black-framed glazing, warm timber, stainless steel and bright green planting. A grout colour close to the tile creates a calmer, more continuous floor, while a contrasting joint makes the tile format more visible. Always view the tile and grout together before installation, as daylight and surrounding materials can noticeably change how the colour appears.
Each box contains 1 tile and covers 0.54 m². Enter the required area into the Timber Wharf calculator and the quantity will be rounded up to complete boxes. Include an allowance for cuts, edge details, breakages and future repairs. Irregular areas and complex laying patterns normally require more allowance than a simple rectangular patio.
Check all boxes before fitting and mix tiles from several boxes so that natural-looking tonal movement is distributed evenly. The base, drainage, fixing method, joint width and movement joints must suit the specific site conditions. Outdoor installations should be planned by a competent installer to manage water and temperature changes correctly. Clean with products suitable for porcelain and avoid leaving installation residue on the finished surface.
