There are four floor drainage kits available - two for concrete floors and two for suspended floors. The Dallmer drains come with swivel knuckle ball joint for easy alignment to a 50mm diameter waste pipe, a removable trap for easy cleaning and a 100mm x 100mm stainless steel grating. The concrete solid floor version can be used in conjunction with the MIRA seal manchets and Mira tanking system shown on our webpages. The DALLMER kerdi drain is for suspended timber floors.
