Not my approach, as a company, to trust chemical/mechanical bonding of glass shelving in a bathroom environment. More than likely the shelves are supported by the tile. I do not attest that epoxies and silicone would not hold the shelves, just not what I would specify. No risk reward for doing so.

The advise that you get from houzz.com is from professionals like myself and also from people who aren't professional but who enjoy commenting. The site is not really set up for solving very complex designs such as a complete house. I enjoy taking a few moments out of my busy day helping out when I can, but there is no compensation involved and I can't spend much of my time here. Houzz can also be used to find a professional to hire in your part of the world. We have clients who have found us through houzz. I don't know if there is a pro near you, but hopefully you can find a local architect for you to help you design your house. Of course you can post any questions that you have and you never know what great answers you will get.

I agree I need a customer wall to wall solution and maybe a full mirror for a small bathroom would look good. The challenge coming are those electrical points. Also someone guide as to what is the right width of the mirror I should put incase I just decide to put mirror over the sink? Is there enough space for framed mirror? The width of the countertop is 26 inch and the height from countertop to sconce is 52 inch. Thanks a lot

Refer the sketch plan for details Its very simple and interesting, BED SIZE 6'6"x 5' queen size, with small 1'6"x1'6" size tables , keep the bed aligned to the door as shown in yellow dotted line, make sure the bed have round edges, as its a small room you might hit your leg while walking across. do a wardrobe in front full size 2' wide, or option 2 do wardrobe and a study at window side, about now about the aesthetics decor the wall behind the bed have a cushion head board at back side of bed. KEEP AC ON THE toilet wall itself its good to root the copper pipe to the service duct where you'll have your outdoor unit.
