I am remodeling the bathroom on the main floor of my house. It is a long, narrow bathroom (5' by 12'). My current question is about the use of tile in the tub surround. In our former house (a beautiful Craftsman) the bathtub surround was all square tile, but the grout eventually became disgusting and failed. We tried to repair it, but were unsuccessful. When I remodeled that bath, I used Corian solid surface for the surround, tub to ceiling. I loved it! Cleaning was a breeze -- no grout lines!

But now, I'm counting the cost of doing it again and tile seems to be so much more affordable. What can I do to make the grout more secure? Will I always regret that I didn't use the solid surface? I'm ok with the look of tile, but I'm worried about the maintenance. Suggestions, please!

I've attached a picture of the Corian surround -- that was one of the things that made it hard to leave that house!
