Is Kerdi Advised For Kitchen & Bathroom Walls?
Hi everyone, I’m going to be tiling the walls of my bathroom and kitchen, and want to know if today’s “best practice” is to put Kerdi or other membrane over the greenboard for walls in these rooms?
The bathroom is just a W.C., no shower or bath - it is the restroom for a small cafe. I’m required to have a floor drain, so I’m planning to use Ditra and Kerdi to waterproof the floor and the lower 6” of the walls before tiling (on the theory that when staff see a floor drain, they’ll assume the floor is waterproof, so it better be).
But I was not going to extend the Kerdi any higher on the bathroom’s tiled walls - unless you all say I should?
The kitchen is a small commercial kitchen for that same cafe. Similar plans for the floor (Ditra then tile on subfloor, Kerdi for bottom 6” of walls). There are multiple floor drains and if staff get very enthusiastic about cleaning and dump buckets of water on the floor, I want the floor to watertight.
Again, I was not going to extend the Kerdi higher than 6” up the walls - unless I should?
Some of the kitchen walls will be tiled, in the cooking and dishwashing areas the wall covering will be stainless steel sheet.
Thanks for your advice!
