RJDL 5 Outside of the tiles have a rubbery feel, which is great for water-resistance. Seems simple to install, but over a large space, it is REALLY hard to do properly. The gray "grout" margins in between each white tile are really small. And that means, if you're off by 1mm, then it doesn't line up properly. So, it looks crooked or off. This is 100% user-error. But, I imagine all of us will struggle with this. So, just be aware: this is hard to do. Not impossible. But, it's hard.
