Installing a kerdi drain involves materials like the kerdi drain itself, kerdi membrane for waterproofing, sealing tape for joints, and mortar for fixing. Essential tools include a notch trowel for spreading mortar, a utility knife for cutting materials, a spirit level for leveling, and a caulking gun for sealing gaps. Leading manufacturers include Schluter-Systems, offering various kerdi drains with features like low profiles and adjustable heights. Subcontractors such as plumbers and tile installers can assist with installation, ensuring proper drainage and tiling.
