Would this be ok as a substrate?

Was planning to put this over grouted tile. Is it safe?

The textured side of that would be hard to clean IMO.
Textured tile is easy to keep clean and, sanitize. I you shouldn't use grout or thinset or, glues. Just put them in by laying them on the floor tightly. Plus, tile will cost a lot less.

I agree and it looks slippery -- I would leave the tile as is --- did you get a slated ceramic tile? Something w/ texture ?
