Oh man, have fun cleaning every single time you do anything near there. To me, a mirror as a backsplash just isn't practical. It's going to get so dirty and honestly, I don't need to watch myself cook.

I would also hate to see my harried expression putting dinner together -- just seeing myself in the microwave over the coffee maker at work is a bummer! But beyond that, people who use slab glass backsplashes often use something else behind the range because the heat can crack a solid pane of glass. So if you mirror elsewhere, you might want just stainless sheet behind the range. Maybe stainless everywhere would be easier? (imagine seeing all your counter clutter twice! eep!!)

you will be cleaning that mirror daily:)

I agree -- not practical in so many ways. Note the stove in your example has a back panel which would help protect the mirror.

We have our entire kitchen's back splash mirrored. It really does open up the space, but there are so many days I wish we hadn't. It is very tedious to clean. It requires microfiber towels only because even higher end paper towels leave fibers you can see with under cabinet lighting. If you spray anything to wipe the counter, get ready to clean the mirrors too because inevitably you will have over spray. We have been remodeling. I talked the husband into getting the entire interior of our home repainted, refinishing our hardwood floors, and new tile for the kitchen and guest bath... I'll fight the tile battle another day! Haha.
