Comparing Traditional Shower Systems to the Schluter Shower Kit

If you are planning to renovate your bathroom and install a new tiled shower, you may be wondering what kind of system to use for waterproofing and moisture management.

There are many options available on the market, but broadly speaking they fall into two categories: traditional shower systems and bonded waterproof shower systems.

The Schluter Shower kit is a popular type of bonded waterproof shower system that is loved by professional contractors and DIY enthusiasts all over the country. Let’s compare and see which option is best for your new bathroom!

What Are Traditional Shower Systems?

Traditional shower systems are based on the principle of creating a waterproof barrier between the tiles and the underlying structure. To achieve this, they involve several steps and components.

  • First, a mortar bed is installed over the subfloor and sloped to the weep holes in the drain. Then, a waterproofing membrane, such as a pan liner, is placed over the mortar bed and clamped into the drain.
  • A second mortar bed is then installed over the membrane to provide load distribution and a bonding surface for the tiles. A curb is also built and wrapped with the membrane and covered with tiles.
  • Finally, a wall substrate, such as cement board, is attached to the studs and covered with tiles, and a sealant, such as caulk or grout, is applied to the joints and corners.

Benefits of Traditional Shower Systems

Traditional shower systems have been used for decades and have some advantages over bonded waterproof shower systems. For example, they are familiar and widely accepted by many builders and contractors who have experience with them.

They can also accommodate any type of drain or plumbing configuration, which can be useful in some situations. For heavy tiles or natural stone, traditional shower systems can work really well as they provide a solid and sturdy base for extra support.

Drawbacks of Traditional Shower Systems

While traditional shower systems have some benefits, they also have several disadvantages that can compromise the performance and durability of your tiled shower. For instance, they are time-consuming and labor-intensive to install, requiring multiple steps, materials, and trades. This can increase the cost and complexity of your project and delay your completion time.

They are also prone to leaks and failures due to improper installation, movement, or deterioration of the components. This can result in water damage to the structure and tiles, as well as mold and mildew growth. Furthermore, they do not allow for easy customization or design flexibility, as the shape and size of the shower are determined by the pre-fabricated components. This can limit your options and creativity when planning your bathroom.
