Experts at Trex, the world’s leading composite decking manufacturer, predict that earth-inspired, nature-driven colourways will set the tone for outdoor living design in 2026.
According to the brand, natural sandy and soft grey shades have led sample requests throughout 2025, signalling continued demand for subtle, organic aesthetics in outdoor projects.
Trex’s Biscayne shade remains the top seller across the portfolio - a light coastal brown featuring a realistic wood grain, influenced by the mangrove landscapes of Florida.
Part of Trex’s Transcend Lineage range, which launched in the UK market at the start of 2024, Biscayne has maintained strong demand throughout the year, suggesting it will continue to appeal to homeowners planning deck projects in 2026.
Trex’s second most-requested shade for 2025 was Island Mist - a cool blend of soothing silver tones, from the brand’s Transcend line. Designed to emulate the naturally weathered look of driftwood, it offers authentic colour variation and a highly realistic grain pattern. In third place is Calm Water, a versatile mid-grey option from the Enhance range that continues to prove popular for its easy-to-coordinate, design-friendly aesthetic.
Lee Heitzman, Trex’s UK and Ireland market manager, said: “Biscayne remains a firm favourite with UK homeowners. Its premium finish and authentic grain deliver the calm, timeless aesthetic that homeowners want to achieve a natural looking outdoor design.
“We’re seeing consistent interest in nature-inspired neutrals, but there has been a subtle shift within that palette. While two of our top-trending colours remain unchanged, Rocky Harbor has been overtaken by Calm Water, suggesting that homeowners are leaning toward slightly deeper, moodier grey tones for their outdoor spaces.
