I would recommend going a darker colour too! We have done it several times with clients who (like yourself) can't see what the finished concrete aggregate will look like until afterwards and the darker the better we have found. Like Zaffa said, it would be amazing if you could extend the concrete into the bathroom, as that can be absolutely beautiful and this aggregate look is a fantastic addition to a bathroom. However if you want to break it up I would go for a dark charcoal (large format) tile so you don't risk clashing colours. Darker bathrooms are really stylish so you don't risk sacrificing on style. Don't hesitate to contact me if you need any help selecting specific tiles as we know how overwhelming it can be and are happy to help. Best of Luck, Jordan from JFI Studios!

I will be the loan naysayer and go: Vinyl Plank timber pattern tiles. I did these in my kitchen and they helped make the room. Used Karndean, but any European brand should be fine (avoid American and assume they are using American or worse if they don't say the country of origin). http://www.karndean.com/en-au/floors/landing-pages/new-looselay-longboard?gclid=CjwKCAjwspHaBRBFEiwA0eM3kQ7eEFPH5FlK2IwV3o7ZsbbmJ19srG0OM_tWK5dhPMNyDdwxGPUr4BoCoYcQAvD_BwE Caveats: Ground must be FLAT. 100% flat, ruler FLAT. If not you will have to level. If flat, you can lay them yourself. Our floor had to be levelled and it was tough. still got a few high patches and gaps because of that. However I have done it on a concrete surface myself since and it's beautiful. Benefits: Nice and soft on the foot. (less ankle pain) single tile replacement. Looks fantastic. No PVC glue fume issues and fairly resilient. Do be wary though of metal chair legs scraping the floor. Waterproof! when installed right with no gaps! (why I would choose them in a kitchen over timber or Eeek carpet!.... Yes previous owner installed shagpile carpet in the kitchen).

If the renovation is taking full advantage of the north, then the porcelain tiles will warm up during the winter months from the sun. If you have wooden floors in the direct sun, they may start to fade. We have porcelain concrete look 600x600mm tiles, with rectified edge. Very pleased with the look. Have been laid for almost 5 years and have no scratches etc.

. Concrete is fine on pinterest, it's even fine in corporate canteens but it's not a homely feel at all. If however you are sold on the look but want a more removable option I can recommend lino. NOT vinyl but real, Lino. It's a different thing, harder wearing than vinyl and can actually look very chic and more closely match concrete look without creating an unpleasant surface to walk on in bare feet. The worst thing about hard floorings like tile and concrete is they are unpleasant on your feet in winter. I live in a house with lino however and it's much warmer and a better feel on the feet than a hard surface flooring. Easy to care for and importantly easy to remove when you get sick of it. Marmoluem is a true lino, which BTW is actually a very sustainable and organic product. Lino is made from jute, seed flours and linseed oil. It's compostable. But it's unique composition is what also gives it a warm and beeswax like feel underfoot, which is very comfortable. You can get it in a some very nice concrete like shades, patterns and even raised textures. It's a sheet flooring so there are few joins, something tiles cannot offer. Tiles, once stuck to the floor are an absolute b****h to remove without a lot of damage, noise and expense. Lino can simply be lifted like carpet.
