Depending on your overall design, using different colours/grout and limiting them (just kitchen or 1 bathroom) they will be en-vogue for years to come. But like all popular designs/products they have their time too. We're using the pattern just not black/white in our kitchen. I'm sure I'll be sick of them at some point years from now and have to update the kitchen - nothing new there!

anaewlo - did all this just over 12 months ago so know how valuable an extra pair or eyes and a clearer head can help. The "little" things are the ones so easily missed and the ones that make you ask "what was I thinking" or "how did I miss that". You could take the tiles up higher immediately behind the hotplates, the range hood would then tie it all together and you could even have some nice artwork each side of it. The only concern I have - are the 2 tiles in the second row centred over your hotplates? Fine if they are as you will have that high part nice and even. If not, I'd a have good think about it. Otherwise, assuming you will paint the walls in a semi gloss paint, the lower tiles will take the brunt of the oil and what goes on the walls will be pretty easy to wash off, it is just a matter of wiping it down after each cooking session. There are times to match things up and there are times to blend. With your downlights, keep to white (assuming you will paint your ceilings white). this way they tend to disappear into the ceiling

My current kitchen has black subway tiles with white grout and everyone loves them. I bought my house with the existing kitchen and have changed the accent colour of the light shades and accessories from red to green in the last year (photo is pre green!) as I love retro mid bright green. Herb plants and glass containing cut herbs from my garden plus cheap black metal indust chic shelves that house lovely green china items also help soften the tiles. I would ideally change the benchtops from white laminate to med rimu type wood and steel, go for a darker grout for practical reasons and change the cupboards from this grey/dark brown laminate to lighter wood (not scandi white type though - I think is now getting dated and is to me a very cold style and not practical). I have my own style, love colour pops and I would best describe it as eco retro boho industrial chic - eclectic. Go for your style and if its not your forever house - think budget and what will be easy to update. I think subway tiles work well for updating and are classic but perhaps think colour instead of white or black as well and also grouting colour - it makes a difference.

As said above the metal strip is generally installed during the tiling. I just could not sway my hubby to go with a capping tile in our budget ensuite reno, but in hindsight he agrees we should have.... Anyway, I decided to tape the tiles and paint over the grout as with the darker paint colour it helps it recede. The grout line isn't too noticeable from a distance thankfully, but here is a close up which might help you decide what to do
