Sold per unit. One unit = 100mm of drain length. Please buy as many 100mm increments as you need to make your drain, rounding up to the next whole unit. Example: for a 2,035mm long drain, buy 21 × 100mm units ($420). We recommend measuring the full width of the room or shower area, then deducting 50mm from each end (100mm in total) to allow easier cleaning around the drain. Tell us the exact finished drain length required. If you wish the drain outlet to be inserted, measure from one end of the drain to the centre of the required outlet position and clearly identify that end. With these measurements, we will glue the end caps onto the tray and cut the outlet opening so the drain outlet can be fitted. For a coordinated, stylish bathroom, match your drain colour with your tile angles, handles where fitted, taps, towel rails and other accessories. Pickup only. Delivery is available only when added to an existing tile delivery.
