As you can see these toilets are pretty well thought about.
The dark basement style, industrial, subway feeling it has got makes it all the more appealing, especially when the lighting is so delicate. Bringing a little feminine side to it.
The second feature that I would try myself, is the the way tiles have been cleverly laid. The slightly smaller subway tile has been used in such a nice dark Grey colour, which fits really well with the dark underground feel. The best part is the fact they haven't been laid in the usual horizontal way, they have laid them on the diagonal. So there is a feeling of the room opening up the higher you look up. Hard to explain really, so best you get yourself down there for some good grub and great interior design.
