Design Freedom, thank you for your response. The mirror is app 75" x 48". We are currently under construction, but here is the matchstick (think that's what it's called) tile I want to use to frame the mirror - about 3 or 4 rows. It has a netted backing. If I leave it on, then it would need grout bc you can see the netting. If the netting is removed, then the spacing is off, or would I just eyeball it? One of the photos shows the edging where you see the reflection of the backing. What should be used so as not to see that? Hope I'm making sense.

Anyone have any ideas? I called tile store and one guy said the Schluter trim.

I wouldn't attach the tile to the mirror. I'd attach it to the wall around the mirror instead. And grout is not for attachment. You need adhesive for that.

Thanks groveraxle. I said that wrong. I meant using non-sanded group b/c there are spaced b/t each piece where you can see the netting. In my instance, the mirror takes up all the space on the wall, esp. on the left where there's like .5" and limited space on top and on the right - so no room for tile on the wall itself. Given my situation, would you use tile for the mirror at all or is it simply not a good/safe idea? If not, my other recourse is mirror mate. I'm wanting to dress up the mirror.

Had to look up MirrorMate. I like it better, I think.

I framed the mirror in our guest bath with glass tiles. It is essentially a picture frame around the mirror. The tiles are mounted on underlayment and I used stock moulding from Lowe's for the exterior frame.

Margaret, what is underlayment - is it a board or thinner like fabric? Sorry but I'm such a novice and am trying to learn so much with my remodel. Did you assemble this right on the mirror? If you could walk me through the process, it would be so much appreciated. Your mirror is lovely. The mitres look great. Are those Schluter trim pieces? Can you give me all the supplies you used?

Underlayment is like a thin plywood, can be found at the hardware store. I used tile mastic to adhere the tiles, added trim moulding around the edges and grouted the tile after the frame was attached. getting the tile laid out was fairly easy, I used three sheets and separated them in thirds. The tile cuts and getting the corners right just took practice. It is a moderately difficult project, but was very time consuming due to my OCD.

Oh how I can relate (re OCD). I want a good finished project as well. I looked at your other projects and love them. So back to the issue at hand....see if this correct. You cut the underlayment to the size wanted for the mirror, so in my case in 4 mitred pieces (one for bottom, top and sides) since my mirror is so large. Then use mastic to adhere to the underlayment, then put the pieces on the mirror - what did you use? Since I have a long span of 75", do you think this is too heavy to be one piece? Lastly, did you use any trim or something else on the inside of the frame so as not to see any backing in the reflection? Whew!

Ok this is a really rough sketch. Please keep in mind a 72 inch span of tile with a plywood back is going to be very heavy, you may be better off with basic wood frame.

Thank you for the visual. It really makes it understandable. So once it's done, that's going to be some finished product in weight. What do you use to attach it to the mirror? I love my glass tile and it should be beautiful if I can accomplish this project.

I did not attach to the mirror, it is attached to the wall.

Oh now I see that. I'm kinda afraid now because of the weight. Your work is beautiful.

I did this probject but I put the mosaic tiles directly on the mirror. This was my first DIY project and it was really easy! I kept the mosaic tiles on the netted back and used the SimpleMat product (which is amazing by the way). The SimpleMat product is essentially a super durable double sided sheet that you stick onto the mirror, then stick the tiles (back netting and all) directly onto it. Then I used unsanded grout to finish it! I highly recommend the SimpleMat product!

Thanks for the tip, Shannon. Your mirror looks great. So how did you attach it to the wall?
