I think being a very small bathroom we've decided to do all white matt wall colour and dark tiles for the floor. Let see how it turns out. We're going to add features such as lights and mirror with frames around it. I'll send before after photo.

I have done lots of pondering and lots of wandering. Wearing out shoe leather looking at tiles, hopping in baths, sitting on toilets. I think I have found my tiles. It's funny to think I started off wanting carrara (or a version/copy thereof), then went to black and white, and now these. The colour really does vary depending on the angle and light. These photos were taken with my ipad, so not true to colour. They are an ash tone and throw grey, off white or a bone colour depending on lighting and the angle. I think they say "classic and elegant like a little black dress, a string of pearls and diamond studs." I hope they don't actually say, "i've turned into my mother and I'm playing it safe." I figure I can go wild with towels. Question is should I lay them horizontally or vertically? The feature tile will go up the side of my wall on top of the bath and be directly opposite as you walk in the door. I wonder if i should use the floor tile or the festure tile on the side of the bath? I am thinking a black tap on the vanity (not necessarily this tap), but chrome elsewhere? The U.K. Has a version of the showerhead with a black rim, if I could be guaranteed it would fit and work the same here I would be tempted to buy it. Black or chrome accessories (towel rails, soap holder etc)? All suggestions, viewpoints etc welcome.

The only thing that is really ugly with this bathroom is the floor tiles and old shower screen. I'm all for getting new shower screen install. Repaint the whole bathroom with tile paint and for the floor get good quality water marine grade merbau timber and put timber decking over the bathroom floor. New shower head and tap fittings if you see fit.

Sounds like a very stressful situation! If there is absolutely no way the builder will allow you to change things (even if they did, I imagine they would ask you to foot the entire bill of pulling the tiles down and replacing all water proofing in addition to new tiles), I can make a few suggestions for improvement. Firstly I would suggest replacing the tiles above the vanity with a white mosaic, a patterned or a textured feature tile/strip. You could also use this same tile to replace the vertical feature in the shower. There are some beautiful shapes and sizes available to choose from. Secondly I would address the grout situation in this way: Floor - dark colour grout & Walls - Light colour grout. Lastly if it does not prove too difficult or expensive, maybe replace the tiles below the vanity with a plain white tile (could be similar size). Good luck and I am sure once you have a lovely mirror up and some crisp white towels, it will look just wonderful.
