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?

Yes the options here are quite limited. I have heard the suggestion of getting clear switch covers & painting them on the inside to match/coordinate with wall colour, but they are still plain covers at the end of the day.

We went for Clipsal Slimline. Very low profile and look great on a white wall. We did not want any "bling" which would stand out or so easily date, like many of the other power points on the market. Also very economical, so you can put your money into the light fittings!

Hi Susan , thanks for your reply and update . It sounds amazing !!! I too have ditched all marbel whatsoever in our home. In the end I chose all black cabinetry ( polytechnic black Wenge) it was slightly warmer and has a grain. My bench tops are all Caesar stone osprey , including the kitchen island , scullery and benchtops. I have a large window splash back that runs along the oven etc . but also quite a lot of walls which I have tiled in an offshore herringbone .The colour of all painted walls throughout solver white delight . We have concrete slate tiling and the white warms this space. It sounds as though we have headed in a similar direction ! We are at the stage of build where the cabinets are getting installed / I'll take a pic and send - I'd love to see yours also ! Here is a pic of a kitchen that has the same elements and colours that I chose .
