So many opposing, I actually love it! Just re designed our ensuite and as you walk into the bedroom you can see our beautiful bath under a leafy window! And shower is in full view- we don't have issues with nudity. The toilet is more hidden behind a book though, There is lots of airflow and no dampness. I do have an extraction ceiling fan, Obviously you can still get privacy, and we have another bathroom to use for the smelly stuff (lol) or if one is waking earlier than the other to get ready for work :)

Caulking should be neat and smooth and NOT hit you in the eye visually. Personally, I'd probably be having a tiny "not really happy" moment (and phone call, and email) over it - but then that's me. There is no earthly reason why a clear sealant couldn't have been used other than whoever did it was either lazy or not interested and the supervisor for the job didn't check it. As for the agents agreement that it could be taken back a little - blow that for a joke - it should be stripped out, clear sealant used and the job done in a professional trademan like manner as this is a new build and if you wanted an amateur to have a go - you'd have done it yourself rather than paying for "skills". Sorry, this stuff really bugs me - I'll get off my soapbox now. :)

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.

I am just wondering whether it is a good thing or not to go with solid colours like the dark blue (prussian blue), grey floors and white on other walls all in tiles. I see that a lot of designers seem to do a pattern on one wall, but I haven't found one suitable and whatever I do, I just don't want it to look out of date in 5 years time. I am not sure how about much of the prussian blue tile is appropriate in order for it to be noticeable but not too overpowering.
