At Centura Tools, we choose our inventory based on the products the professionals of today enjoy. Our Kerdi pre-sloped shower trays and shower membranes are on that list. Having the right slope in the shower is important to encourage the water to go toward the drain and prevent standing water around it. The Kerdi pre-sloped shower trays eliminate the need for a mortar bed, thereby reducing weight and installation time for your shower system. There are many sizes available, including an off-centre drain option that works great for bathtub replacements.
