How to finish edging on mosaic kitchen splashback tiles?

We are using these tiles for our kitchen splashback and wondering how best to finish the join at the window sill. Should we

- cut mosaics into a straight time and then use a tile edger

- use a subway til on the sill itself with tile edger covering the join between mosaics on wall and subways on window sill

Or is there a better /easier way to finish?

Many thanks for your help

Hello @blodynlisa

Thank you for sharing those extra photos of your kitchen wall. I propose looking at the QEP 10mm x 3.0m Silver L Shaped Tile Trim Angle or the QEP 10mm x 2.5m Aluminium Round Edge Tile Trim. These are the most typical trims used on ends, corners and window edging. If you wish to see what the profile will look like against your tiles, I propose purchasing both and testing it against your mosaic tile sheet (you can exchange the one you don't like). Once you have the trim on, you'll get a better idea of what they will look like once attached. If you are happy with the look, you can then commit to the profile trim you've chosen.

If you need further assistance, please let us know.

Hi @blodynlisa,

It’s a little hard to be certain from the photo, but from what I can see, it looks like you’re working with a solid tile that is designed to mimic a mosaic pattern, since the grout lines appear to be pressed into the surface rather than made up of individual pieces. If that’s the case, you can finish the edge in the usual way by using a tile saw to trim the tile to a clean, straight line so it can butt neatly against the window reveal.

If the edge will be exposed, you can definitely use a tile edging strip to cover that join. This takes a bit of pressure off achieving a perfectly crisp cut on the tile edge and gives you a clean, professional finish. The best approach really depends on how the sill sits in relation to the wall. If the sill is proud of the wall or creates a stepped transition, that may change how you handle the junction. A photo of the sill and a quick indication of where the tiles will run would allow our members to give you more precise guidance. But in most cases, you’d trim the tile flat, bed it in adhesive, grout the joint, and add edging if you want a more polished finish.

Please let me know if you have any questions.

apologies for the prior photo of the tile not being clear - the tile is on mesh and contains small mosaics, not a solid tile.

Here is a photo of the window sill, we have since removed the old adhesive.

Would a tile edging strip be suitable if we use the mosaics on the sill as well as wall? As opposed to using a subway on the sill that meets the mosaic at the join of the wall and sill
