For the sanitary ware go with wall-hung or standard close-coupled toilet and basin with pedestal with acute angles and a contemporary design. Abstract towel rails and wenge wall-hung furniture fit well in the fantasy bathroom giving it that calm almost surreal look.
You don't have to settle for ordinary when it comes to bathroom basins. This is your opportunity to make a change that will upgrade the look and give you a fresh style in there. Yet it isn't expensive and it isn't hard to do on your own. While you need it to be fully functional there is no reason why it can't be beautiful too!
The ultimate luxury in a fantasy bathroom would have to be a waterproof TV. You could even think of doubling the bathroom up as gym complete with exercise bike and rowing machine. Ornaments should be unobtrusive so choose things like small piles of pebbles and modern wall prints over candles and nick-nacks.
