Backsplash - adding to new kitchen

[NickK]

so we have spent time looking for a good tile that will cover behind the sink and the gas hob. Essentially ~2.3sqm of tiles.

Going with a reflective blue mosaic behind the hob (9patches) and touchline smoke behind with 400mm height behind the work surfaces (83tiles).

Plan is to use white powder mix adhesive and then a light grey or white grout. Followed by sealing between the work top and tile (tile will sit on worktop). The top of the tiles considering putting a metal top for a clean non tile edge line.
Standard straight tile edges and with spacers. The mosaic is approx 30x30 patches so should be straightforward.

We have a biatch of a wall that is not entirely flat so I will need to carefully thing about the metal edge on that.

Any suggestions or thoughts to include into the thinking up front?

Consider going with the grey grout. My kitchen guys said that white gets grubby and you can never really get it clean back to where it looks white again. Since they said that, I've noticed it time and time again at other places where they've used white on floors or busy cooking areas. One solid splashback with no grouting ensures that doesn't happen.

The floors are grey tile with light grey grout. So happy to continue the light grey onto the wall tiles.

Just that the reflective blue mosaic had white in the shop, however it shouldn't look too bad. If the mosaics turn out to be a PITA we could always rip out and replace with a 6mm glass splash back for that area. A couple of places do custom colour matching to Dulux etc or image so it would be easy to work out a good colour match.
