I'm a power tool packin' woman! / And a TILING question....

Oh how I love my Dremel tool. I'm redoing the grout in our master bath shower - part of it was cracked and since it was never sealed, it was stained and ugly after 7 years of wear. So-got my grout removal tool out and in two hours I got most of the grout removed (totaly in some places and others just down 1/8 of an inch).

I love power tools!

Just had to share!

Now about the tiling question. If you're going to do a backsplash around the kitchen counters - do you have to put up backerboard or can you tile right over the drywall (would seal it first). I could look it up on line - but thought I'get better advice here!

Thanks!
