Which size and shape of Diamond drain should you choose for your wet room — the 120mm square, 300mm linear or 600mm linear?

Match the drain to the size and layout of your wet room: the 120mm square tileable grid is compact and works well in a smaller ensuite or where you want a discreet centre outlet, while the 300mm linear is a good middle-ground for medium showers and gives a sleeker, contemporary line. The 600mm linear is best for larger wet rooms or where you want a long, minimalist drain run along a wall to speed water clearance. If you use large-format tiles, a longer linear drain helps water sheet off the floor more evenly; for mosaic floors the square grid can blend in neatly.

Can you tile over the drain so it blends with your floor?

Yes — all Diamond drains listed have tileable covers or grids designed specifically to accept tiles, so your floor can sit flush over the drain for a seamless look. For example, you can lay the same porcelain tiles over the 300mm or 600mm linear cover so the drain becomes almost invisible along the shower edge. The tileable finish preserves the minimalist aesthetic while still giving you full drainage performance.

How easy are these drains to keep clean and hygienic?

Very easy — Diamond drains include removable tops so you can lift off the cover and clear trapped hair and debris without special tools. Regularly removing the top and rinsing the waste area keeps flow optimal and prevents odours, and the corrosion-resistant finish helps the visible parts stay looking fresh. In a busy family bathroom, a weekly quick clean will usually be enough to maintain performance.

Are Diamond wet room drains durable enough for a family bathroom or commercial use?

Yes, they are built to resist rust, corrosion and wear, which makes them suitable for high-traffic family bathrooms and long-term residential use. The product line is described as engineered for durability, so you're choosing a drain that will retain performance and appearance under frequent use. If you want the strongest everyday performance, a larger linear drain gives higher throughput and distributes wear across a wider area.

Will these drains give you reliable drainage performance for different shower setups?

Diamond drains are marketed for powerful drainage performance and come as waste kits, so they are designed to handle the typical flow from wet room shower trays. Linear drains (300mm or 600mm) generally move water away faster across a run and are excellent for curbless, walk-in wet rooms, while the 120mm square grid provides efficient central drainage for smaller trays. If your shower has multiple heads or a very high flow rate, the 600mm linear will give the most reassurance.
