Shower Systems

Shluter vs. Wedi

A question we get fairly often is ‘Which system is better, Shlueter, or Wedi?’ The answer is, there isn’t one.

Wedi and Shlueter (Kerdi board by Shlueter systems shown here) are both brands that manufacture water proof backings for tile. Both brands have products for subfloors, but they both really shine when used in making a custom shower. They can be thought of as the modern high-tech versions of fiberboard or cement board.

However they are much more than just boards. Both brands also have a ton of accessories , waterproof caulking , thinset, waterproof wraps, shower pans, and even drains. When used in conjunction with the Kerdi or Wedi boards these are typically refered to as ‘systems’. If you were to ask any two tile installers which product is superior you will likely get two different answers.

Both products are extremely good at their jobs and while there is not a clear winner, there are some subtle differences.

Most experts agree Wedi is stronger and even more water resistant than the schlueter equivalent. Though when properly installed water will not be an issue with either option. It is also much more easily repaired after tile installation.

The Wedi system (shown below) is also significantly more expensive. 20-40% more. My opinion is it is more difficult to install than Shlueter systems, but tile can be installed on top of it on the same day where as the Shlueter system requires more drying time.

Wedi will leave you with a nearly perfectly flat surface to start with but the Shlueter system will have very slight raises from the membrane covering the screws.

The Shlueter system has pre built curbs, niche’s, benches and more. While wedi is stepping up their game in that front I still think Shlueter has more options. Shlueter systems has also been around significantly longer. Though it is worth noting that both options have an excellent track record and warranty.

If this blog has only served to make it harder for you to decide between the two systems your biggest takeaway should be that both products are truly excellent. For the total cost of a custom shower they are both well worth the upgrade from old school fiberboard/ cement board. If you are not installing the tile yourself ask your installer which product they prefer. Let me know what they say in the comments.
