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.

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?

use glass with water proof panels which are water resistant as well. here soft closing fittings would be nicer. may choose diff glass to enhance the beauty or keep it opaque so clutter inside the cabinets is not visible.

nothing u can do.. ur flat layout is very different and the toilet blocks has to be nearest to the duct side, and if u want to shift some other place , then it possible only when u break the existing flooring tiles with coba below to pass the wc pipeline and for that u have to raise the floor small area portion at least by 6" height excluding the floor coba height, i:e, after floor tiles... and the living & kitchen can be replaced the position only for the common toilet to shift
