I would look at this room from 2 angles, in this order: convenience (as you have young kids and need everyone to be able to fully use it) and aesthetics. Equipment and accessories: #1 - first look at what is necessary to have in this bathroom: a place where to keep soap, toothbrushes, toothpaste -- all within easy reach for all users (including not-tall-enough kids) #2 - a cosmetic mirror ? #3 - a towel rail #4 - a small cabinet for storage Ideally, #1 should be stored directly on the sink, as it's lower, within easy reach for the kids (see below photo from one of our baths): You can do this also witha smaller sink, like the one we use in the half-bath: If you'd like to keep the one you have (which is really nice), you'll have then to use a shelf (as also suggested by someone else above), and I'd propose one of white porcelain and not one of glass, as it's a lot less reliable with children around. Below, an example of what I mean. The shelf should be installed as low as possible to be reachable by the kids, but also the mirror should be much lower, so that they can use it (much more interesting for them) without having it too low so the adults can't see themselves anymore. For #2 look on the left of the mirror in this photo (if you need it): A towel rail (#3) is absolutely necessary and make sure it's one where you can stretch the towel for faster drying (like the one in the 2nd photo). The cabinet storage (#4) could be placed on the wall from the right of the mirror, as you can see we have in our half-bath (also 2nd photo): Aesthetics: I agree that blinds on the window make no sense, light should be let to flow in as it's much needed in a bathroom. If you don't have time or disposition to paint the walls (and maybe they should remain white anyway, or a light color, because this is a small space), you might use decorations from your DYI center and stick them on the walls (see an example below from my daughter's bedroom, but there are other smaller ones for any kind of space): This way, the room becomes more attractive, more welcoming and more colorful (with very low cost). I hope this helps :-)

Nevermind I figured out what I wanna do http://imgur.com/a/Mzu94 

We have just brought a 1970s home which has painted wallpaper. We stripped the wallpaper in one of the small rooms (about 10m2 of wall). We were hoping to re-plaster and paint the walls ourselves as a plasterer would cost approx. $1,900+GST (including paint). The wallpaper came off easily enough but there are definitely some little imperfections in the old plasterboard which need fixing. Also, the joins between the plasterboard have been plastered but not taped beforehand. We were told that if we want to get a good finish, we would need to cut the groove out, re-tape and plaster over. It may be easier to just replace the gib, scotia and skirtings? Any advice would be greatly appreciated!
