I am not the best person to comment on lights but would a few downlights be the go or one of those integrated heat/fan/light things be best in centre. Also a lot of people have task lighting......so lights just above the mirror for makeup etc. Personally too bright lighting while doing makeup sends me into a spin as I look like i have about a month to live! I hadn't thought of approvals for my proposed window - so thanks for that. Must keep that in mind. My bathroom is very hidden and looks nowhere in particular. It is all looking good. On another note my friend got a heated towel rail and much as I hate wasting power it is fab. Our towels seems to stay dampish in uninsulated BV '60 box in Melbourne. Also i would have a look in bathroom showrooms for some ideas too if you have any handy. Or buy a bathroom specialty magazine. It is going to be so nice this bathroom. What tiles etc?

Ideally you would want 900-1000mm clear space in front of your vanity and for walkways, unfortunately we don't live in an ideal world and have to work with what we have. 700mm would be the absolute minimum width for a walkway to still allow reasonable passage, although I would be reluctant to go this tight. A floating vanity will help the space look larger and storage can be included in a mirrored shaving cabinet or mirror with shallow shelf above the vanity.

Yes bigreader, Celina have a look at Orient House, they bring in loads of beautiful screens and it is a fabulous place to visit for ideas. The idea below is as it says, contact frosting; but I would work out a design and get a professional in to execute. Of course, if you want something more unique and a treasure forever, ask at axolotl.com.au They only work in metal, glass and concrete - but you would never have seen anything like their design ideas. More costly than Indonesian artifacts, but!!! dream on.

Invest in a custom made one from your local glass and glazing specialists - it'll be made to fit the vanity top exactly and the edges of the mirror should also be sealed to prevent corrosion. (which often happens to mirrors from the hardware stores)
