I am in the process of redoing my tile fireplace surround. And I am looking for some design and build tips/feedback before I finalize the design.

Although the current mantel/surround is in good shape we really don't like the tiles. If we just replace the tiles, I think there is so little space between the fireplace insert and the mantel to "show off" the new tile. The plan is to remove the mantel legs and tile a wider section on either side of the i.e. tile the same footprint the mantel legs left. Then install a new floating mantel.

I assume I will need to edge the sides with a schluter strip of sorts...how can I make this blend better?

Any tips on attaching mantels?

Here is a before picture, with a picture of the new tile I am considering.

well, blow me down and slap me wit a fender, arf arf... but I kinda like the slate that is on there now with the wall color.

get some art that has that honey-oak floor color on the wall nearby to bring all the colors together. that's what I'd do.

It's not slate, it's ceramic 49 cent tiles. You're right though...it doesn't look horrible....we're just wanting to lighten up the tile, and eventually the paint too.
