Both are good options. I know with the larger tile (we have it in the showroom), alot of clients think they end up with a seamless look imitating grouted in mosaics but in reality when you lay it you still see 300x300 tiles. I am one who likes texture and would go for the larger one but both are good options.
PS if you go for the mosaic use a charcoal coloured grout makes the metallic pop. If you use white grout all you will see is a white grid washing away the silver metallic look.

i will take the big one any day. the big one has a porcelain FEEL to it and the small one has a ceramic FEEL to it.

Oh, I'm so confused by big and small!! SORRY!!! I said small but I think I meant large!! The closest one in the pic... that is the large one - right????

nope that's the small one. I believe?

I've got the same colour scheme in my bathrooms (white wall tiles, charcoal floor tiles) and have something really similar to the mosaic tiles as features in the tiled niche and shower. Thus my vote is for the mosaics Let me know if you want to see any pictures.

1 vote for small. Looks more modern.

Wow, then I stuffed up too, like Rocketship . My vote was for the one at the front of the pic (with the metallic looking finish).

yep, same here. (front tile in your picture)

But it really depends on while has a better match to your floor tile.

Thank you everyone for or opinions. I ended up with the large 300x300 tile and they look Amazing and really easy to clean so I am happy. Will post a photo hen I get another chance

Ok RS, I was seriously worried there, because I nearly picked the front one for my house and I figured if I liked it, so would you....phew, glad you got mixed up

Bendo cant wait to the finished product, I decided against it due to cleaning but now I'm wondering if I made the wrong decision
