The lighter-- lime green towel would work. I would get a glass soap dispenser and, really, any beautiful piece of glass would work well for a toothbrush holder. You're in India, so you don't want to pay for international shipping, but here's an idea-- take a look at these cobalt blue dispensers on Etsy (and this is just one example-- they're all over the place): http://www.etsy.com/listing/116043015/cobalt-blue-glass-pint-jar-soap?ref=sr_gallery_25&ga_search_query=+glass+soap+dispenser&ga_order=most_relevant&ga_view_type=gallery&ga_ship_to=US&ga_search_type=all I'm not sure the soap dispenser and toothbrush holder have to match anything in particular. I just think beautiful glass is beautiful glass. I mean, take a look at this depression glass pitcher, for instance. If the right size, I think something like that would be unexpected and amazing sitting against that beautiful grey tile. This particular one is rather expensive, but you can find ones less than this and along the same lines. http://www.etsy.com/listing/104529409/vintage-pink-depression-glass-pitcher?ref=sr_gallery_5&ga_search_query=depression+glass+pitcher&ga_view_type=gallery&ga_ship_to=US&ga_search_type=all When it doesn't match, it will seem simply like something lovely (and functional) you've had on hand-- maybe in your family-- for a long time. I feel quite sure you can find beautiful glass in India.

With white fixtures, keep your floors and all tile white or a stone that is mostly white. You can paint the walls above the wainscot (which might be glossy painted wood or beadboard, or you might employ a cabinet for the sink that was painted a very soft sky blue. One narrow trim piece of tile running through the white tile might be the same tone of sky blue. Then, add blue linens / towels / etc. [houzz=] Now, consider what other colors are in your home and select one that is clear and soft and lovely with white. You might use that color instead of sky blue. I used sky blue because it is the color of water and therefore always appropriate in the bath, but you can make the bath flow with the colors you have or plan to have in your home. If this was a master bathroom instead of a common or guest bath, I would shift the choices of stone and tile from white plus white to a lovely off-white, cream, or almond tone - like travertine. Use a neutral like chocolate on the cabinet and add color only with linens and perhaps some art on the wall. [houzz=]

I wouldn't put any water under there because of potential mould issues (in fact, there looks like there's a bit of mould already -- is there?). You could tile the bottom of it and put a strip of LED lights under the glass. What did you have in mind when you initially thought of the idea?

Hi! Yeah it will. You will have to get your plumbing lines capped and replaced. It's not advisable to have a joint in the plumbing line. So the one that you are wanting to pull to the new sink will need a fresh line put in from the last bend it has. I hope that makes sense! Best! Miloni
