I am looking to install tiles myself in the basement for a bathroom floor. I assume I need some type of moisture backing for the tile. Right now its just concrete flooring and is levelled.

What do I need under the tile to begin laying them out?

Hi Mike,

You can lay the tiles on the floor no problem. The only concern is it will be cold on the feet. Installing a radiant floor system underneath the tiles is the best option but not the most cost effective.

Either electric mats can be placed down or a hydronic system can be installed.

You do not need to have any moisture Barrier under your new tiles-I would However suggest using a water emersion rated Polymer modified set cement to set the tile with.

Hello Mike

Here is what I use for basement floor/tile jobs:

Schluter-DITRA and Schluter-DITRA-XL

This is Specifically designed as an underlayment for ceramic and stone tile

and if you wish you can use a heated floor system with it as well, two step process.

You can also go and lay your tiles directly to the concrete, but it will be cold on the feet.
