4/10/2023 0 Comments Tiled showersEven with proper installation, eventually the weep holes can become clogged due to soap, shampoo, body lotions, etc. This increases the potential for efflorescence, grout discoloration, and mold growth within the system. Since the tile covering itself is not waterproof, moisture will infiltrate the mortar bed if the pan liner is not placed on a sloped substrate, the system will not effectively drain the water to the weep holes in the drain, creating a permanently saturated mortar bed. For example, a common error is to ignore the pre-slope installation and place the pan liner directly over the flat subfloor. Methods B422 and B422C in the TCNA Handbook demonstrate the use of a bonded waterproof membrane and integrated bonding flange.Įach component described in the Traditional Method above is essential to the function of the overall system. In the event that a traditional clamping drain has already been installed by the plumber, the Schluter system includes an adaptor kit that can be used to quickly and costeffectively convert the clamping drain into an integrated bonding flange drain. Drains that feature integrated bonding flanges provide a large contact area to allow for a watertight connection between the membrane and the top of the drain assembly. The membrane is installed over a sloped base, either a prefabricated EPS foam tray or a mortar bed, and shower drain with integrated bonding flange using thin-set mortar. The important stages of construction for a tiled shower are the shower base and curb, the walls, the drain assembly and most importantly the integration of these elements for a functional waterproof shower. By examining each of the steps and components required to build a waterproof shower using the traditional method, versus a sealed system from Schluter Systems, it is possible to form a more complete picture of the options and their costs. Many factors must be considered when doing a complete review of systems, including final appearance of the tile installation, material cost, labor cost, ease or complexity of job-site scheduling, and post sales performance and call-backs.Ī thorough comparison can provide some surprising results as costs in one area are often offset by equivalent savings in other areas. There are traditional shower assemblies, sometimes called water in/water out systems, and there are bonded waterproof shower assemblies, also known as sealed systems. These coverings are not inherently waterproof, however, and must be installed in conjunction with a waterproofing system that effectively manages moisture to protect moisturesensitive building materials and control mold growth.īuilders can choose from several different methods and systems for moisture management, but broadly speaking they fall into two categories. For these reasons, tiles are the ideal surface covering for wet areas. Many builders choose ceramic and stone tiles for the showers and bathtub surrounds in their homes because they are durable, easy to maintain, and hygienic – all features their home buyers covet. Explore all KERDI-SHOWER-KIT options here. With a variety of kits to choose from, kits without the drain and/or grate components are also available to allow for more flexibility in flange and grate selection. Available in a variety of shapes and configurations, all kits contain a shower tray, shower curb, KERDI waterproofing membrane and waterproofing strips, pre-formed corners, pipe seal, and mixing valve seal. The Schluter®-KERDI-SHOWER-KIT contains all the components you need to easily create a waterproof and vapor-tight shower assembly.
