When planning a shower renovation or installation, one of the first decisions you’ll need to make is the size of your Kerdi shower kit. rasch, reliable, and easy to install, Kerdi shower kits come in various dimensions to cater to different bathroom layouts and needs. Let’s dive into the different sizes available, their features, and how to choose the perfect fit for your space.
Before we delve into the sizes, it’s crucial to understand that Kerdi shower kits are multi-layer systems that combine shower pans, linear drains, wall flashing membranes, and shower walls. They are designed to create a watertight shower barrier, preventing leaks and damage to your bathroom’s subfloor.

Standard Kerdi Shower Kit Sizes
The Kerdi shower kit sizes offered by Schluter Systems are designed to accommodate the most common shower sizes. They are measured in interior dimensions and fit within the shower curing space, not the finished dimensions.
Here’s an overview of the standard Kerdi shower kit sizes and their key features:
42″ x 42″ Square Shower Kit
The 42″ x 42″ Kerdi shower kit is perfect for small bathrooms or powder rooms. Despite its compact size, it offers ample space for a comfortable showering experience. This kit includes a square shower pan with a centered linear drain.
Some popular configurations with this kit include using same-sized wall panels on all sides or combining it with a bench or niche kit for added functionality.

48″ x 36″ Rectangular Shower Kit
The 48″ x 36″ Kerdi shower kit is a great option for standard bathroom layouts. It provides a good balance between size and space efficiency. This kit comes with a rectangular shower pan and a linear drain located on the back wall or along one of the side walls depending on the chosen drain option.
This size works well with both wall panel configurations and can accommodate niches for storage or built-in seating options.
Custom Kerdi Shower Kit Sizes
For bathrooms with uniquely sized showers or specific layout requirements, Schluter Systems offers custom Kerdi shower kit sizes. These kits are manufactured-to-order, allowing you to create the perfect fit for your space.

Custom Kerdi shower kits can be ordered in dimensions ranging from 24″ to 72″ in width and height, with a minimum shower pan size of 32″ x 32″.
Alcove Fitting Kerdi Shower Kits
If your shower is located in an alcove and has three finished walls, Schluter Systems offers alcove fitting Kerdi shower kits. These kits are perfect for installing shower pans with finished back and side walls and an open front.
Alcove fitting Kerdi shower kits are available in 36″, 42″, and 48″ widths and can be specified with different shower pan and drain configurations to suit your needs.
Angled Shower Kits
For bathrooms with sloped floors or other unique layout challenges, angled Kerdi shower kits are an excellent solution. These kits can be installed on floors with a slope of up to 3 degrees and come with angled shower pans and flashing membranes to ensure a watertight installation.

Angled Kerdi shower kits are available in custom sizes and can be combined with standard or alcove fitting kits to create the perfect layout for your space.
When selecting the perfect Kerdi shower kit size, consider factors such as shower door placement, existing plumbing, and available space. Always consult the Schluter Systems website or a professional installer for guidance on the appropriate kit for your specific shower configuration.
Embarking on a shower renovation project brings endless possibilities, and with Kerdi shower kits, you’re assured a reliable, long-lasting, and stylish result. So, carefully select the right kit size, and enjoy the peace of mind that comes with a watertight, high-quality shower installation.
