I've only been laying tile now for a year, so I'm still getting up to speed. I'm very happy to have found this forum. Here's my question. Has anybody used the Kerdi system to just do the shower pan without the sides? In other words just replace the old way of doing the shower pan. We're doing a condo with about 20 showers in odd shapes with the permaboard already up. To put the pan in the boss wants to pull all the board and put the pan behind it and put the board back. I'm not thrilled. So any help would be great. Thanks
You can do it if you're not concerned about product warranty. Schluter would want the membrane to go all the way up to shower head height. The problem is that the Permabase is not waterproof, and water can wick behind the Kerdi.
