Hello,

I've read some amazing posts from the pros - and am thankful for their input.

I've also been getting some tips from the John Bridge Tile forum, and they also have been very helpful.

I'm in the process of redoing my bathroom and am at the point of getting ready to lay some floor tire.

I've used the Kerdi shower system and laid Ditra on the bathroom floor and a platform for a clawfoot tub.

My concern is that I'm using 1" ceramic hex tiles over the Ditra with a complex border. The hex tiles will be bordered by an outermost line of 4" x 4" tiles, followed by line of 6" x 3" subway tiles and finally a thin line of 1/2"x 6" tiles inside of that with the innermost field consisting of the 1" x 1" hex tiles.

Schluter does not recommend the use of tiles <2"x 2" with the Ditra due to risk of damage in instances of hi pressure loading. There is this risk in my bathroom, as I will be setting a clawfoot tub over the 1" x 1" hex tiles so I do worry about this.

This question has been addressed on the John Bridge forums (http://www.johnbridge.com/vbulletin/showthread.php?t=8779), and per the forum, Schluter has said off the record that if the Ditra squares are filled with a slurry of thinset, the tiles can then be set over this, but there is further discussion of whether the slurry of thinset should then have a layer of SLC over the thinset, then the tiles set over the the thinset

There doesn't really seem to be much of a point of using SLC over the thinset slurry to me, but I want to make sure I do this right the first time.

Any suggestions?

Thanks
