highlight tiles are really not in fashion. it was 5 - 10 years back. i would suggest go with the bottom less distracting simple design throughout. carry dark floor tiles up 3 inches on the wall as skirting. ensure the centre line of your shower fixture and its wall controls lie in the centre of the tiles. that would be your starting point. rest will fall in place. ideally the ceiling height should not be more than 8 feet. if its more you end up with an uneasy proportion. either do gypsum false ceiling at 8 feet or stop the tiles at about that height and paint the rest of the wall in dark grey or purple and have pendant light that throw light below 8 feet. good luck.

Hi, I think full wooden tiles will feel like pathetic. Try disparate like combinations of glossy and wood tiles or like 2 walls and floor with wood tiles and other 2 walls light colored glossy tiles to break the monotony.Thank u.

I have a design I want to do for my small bathroom. I want to blend the existing light travertine tile floor and shower tile and black granite top sink with venetian plaster grassello clean white ceiling with gold wax to give a shiny look to the ceilings along with a venetian style crown molding in the corners.. The colors I want to use are White, Black and Gold. White: ceiling, cabinet, toilet, sink, door. Black: Granite top, wall outlet glossy black covers, sink faucets. Gold: venetian plaster marble-like Walls, light fixtures, towel rack, shower faucet.

Hi Shivam, I hope you are doing good. There is no particular tile size that may look good as it completely depend kind of design you have in your perspective. If you are looking at more traditional interiors then generally smaller tiles with motifs or emblems look good which have a representative geometrical or floral patterns. If you are looking at more modern interiors then generally bigger tile sizes are preferred for clean look less joints.  Regards, deSigneR
