Jonathandb1972, I was thinking of going with a grout that is the same colour or lighter than the grey tile. The hex will be grouted in a medium grey. This has already been done in the loo (the hex) and looks great. Neither are grouted in the above picture. Do you think there will still be issues with where the grout lines are if they are the same or lighter than the tile? Also, where the hex tile in the shower meets the grey tile will mainly be covered by the shower's profile. However, the shower only goes up to about 2m, so there will still be a visible "meeting" of tiles above that. My builder is a little concerned about how this will look as he will have to cut small pieces of tile to fill up the edge, which may stain once they start grouting. I'm keeping my fingers crossed and hoping for the best...

Personally I would get a new upstand and no tiles. Instead a plain wall painted with wipeable paint.

Start with the colour of the floor tiles in situ, the colour of the range, the unit and worktop design / colour. Then find an infill tile that will work with all of that, whilst being of the right depth to work with the old ones. My guess is it's still going to look out of place - possibly! - Therefore, consider having a border tile around the whole kitchen to blend it it.

Hi Aman, I think RGB backlit, toughened glass filling would be really, really nice, especially during the barbecue parties for upcoming summer. After installation, you will be able to change its colours in real time using a pilot or any other kind of device, it is up to you. We can do that in less than two-three weeks I guess but I would need gap dimensions to make an no obligations quote for you. Doorstep will probably look like this, but you will be able to change its colour anytime (All possible colours included). Let me know if you are interested so I will arrange a call with our advisor. He already knows your case so you will not have to explain it twice :). Best! Erwin (Sunstudio)
