No to the grey - your wall seems to have a green tinge in them, so I would say either green/grey or a warm white tile with darker grout. If you choose the right grey/green, it is a classic look so shouldn't date. If you are a bit scared to choose colours, why don't you get a couple of warm white sample tiles and put where the splash back will go. You will soon see if it looks too stark....(maybe another idea, but possibly not a good one - why don't you see if you can put a few pages from a blank sketchbook in the whole area where the splash back will go (not super white white, but a warm white). That could also possibly highlight how stark (or not), the white may look. I can see what design tank is saying, as your cupboards appear to be more cream than white in the photos and if this is the case, then I agree the white will most likely look too stark. My cupboards in kitchen were white (but a warm white not a cool white). The stone bench tops also have the little speckles of stone in them..I can't remember the colour Ocean foam/Osprey.......but even with those colours and them not being cool whites, I thought the white tiles looked too stark against them. I therefore went for a glass splash back and ever since I then went to think of designs for my bathroom renovation, I constantly regret going with the glass in the kitchen and modernising the house too much..........definitely don't do glass if you are wanting to keep a classic charm to the house. In a long winded way, I think yes, I also think you should just stick with the grey/green. It will make a statement. Not the right shade...but another example....it may be hard getting the colour of the tile exactly right given that the walls are already painted and the tiles need to match.

My suggestion is first talk to the builder to see what instructions he gave the tiler as i'm sure he doesn't want a dissatisfied client. Most tilers will check with the builder before grouting especially when a colour is not specified in a contract. I would then ask if the grout could be replaced, from the looks of it it will only be a couple of hours work. There is nothing worse than having to look at something you are not happy with. I would not use the paint product as it will alway look like it is covering a mistake. White will look better. Make sure the mixer body is waterproofed or you will have a leak in your wall, the membrane should lap onto the body from the wall if it is done well. All the best.

Hi Rachel, the staff at Studio M should all be trained colour and design consultants. Take your ideas to them (all your pictures) they should be able to put together a scheme that works with the ideas you have in your pictures. If possible please ask them for samples of the products you have chosen. Don't let them pressure you into making the final choice on the spot - tell them you would like to think about your final choice before you sign off on anything. Take the design plan away and look at it again after a day or so. Your wood floors do not have to match the wood in your kitchen, but it needs to be the same tone/hue (eg light or dark) - what wont work is if you have a grey timber floor then use a brown timber in the kitchen. Classic styles never date when choosing tiles, and choosing one colour. I'm not into matchy matchy, so your bathrooms and kitchen do not need to match, you can bring one element into all rooms to form a connection eg, timber, subway tile. I find that clients who have pictures of what they want make it easier for a designer to help them choose finishes. Good luck

Epoxy grout is common in kitchens , We haven't used in bathroom..Usually more expensive
