Hi Tanya. Very nice colour scheme you have going on there. I think you could easily use one tile in bathrooms and another in hallways, kitchen, etc. as the hues of both appear very similar. Is the bathroom tile also to be used in laundry? You could also have a colourful rug in your kitchen to warm it up if you think the tone of tiles are too cool. Keep us posted what you decide.

Hi nice size kitchen, horizontal lines in your kitchen will make already long kitchen look a bit longer. looking at the pics of your kitchen it looks like u have a lot of horizontal line i would install the tiles lines vertically to bring the balance back. Number of lines will depend on the zones and the kitchen enterance along with dining furniture or vertical wall lights in the room. u may need to take a pic from the enterance of kitchen and draw a few details on the pics then work out the lines. Vertical lines are easy to over do so be careful. good luck

Option 3 has a terrazzo-look tile which references the previous and original bathroom. The concrete look tiles will date, and look quite daggy in ten years time. Best of luck, Dr Retro of Dr Retro House Calls

You are going to have to spend some money to make it look seamless. Doing it cheap will always make it look like a crappy addition. There is no easy, cheap solution to your problem, and you will regret it as soon as it is finished. Best of luck, Dr Retro of Dr Retro House Calls
