Emily, with being a renter, I'd definitely check Pinterest for temporary solutions. I've seen DIYs where you can starch fabric to walls with an iron. Also try temporary wall paper/decals, but I'd test a small area first. Cabinet makers or even yourself would be able to create a flush vanity without attaching it to the wall. Plywood, especially hoop pine, has received a lot of traction. It really gives a clean, organic look that you could have custom cut to fit in the area. You could also use it on the wall – it could be stained, left natural, or painted for a feature. Have a look at EchoPanel. It is a decorative, acoustic pinboard that would add a splash of color/design. If it is above your vanity, you could pin pictures, inspirations, etc.

chookchook2 - we have linoleum in our kitchen. 10 years on, still looks great, easy to clean, forgiving underfoot and dropped items don't always break :) Love it so much, we will be using it throughout our new beach house (except bathrooms). Try searching Forbo Marmoleum - the colours alone are eye candy, and you may find a link to a state rep.

We recently bought a copper strip light from Beacon Lighting to put over the pool table downstairs, and I was really impressed with the light produced from such a slender strip. It comes in two lengths 1600mm and 1200mm. I think it would look great in your kitchen. http://www.beaconlighting.com.au/lighting/pendant-lights/modern-pendant-lights/ledlux-strix-led-1600-lumen-dimmable-pendant-in-copper.html Re your bar stools - a lot depends on your budget. If you're after something less expensive yet still comfortable, you might want to consider a replica Eames DSW bar stool. They come in a variety of colors too. (And can be found quite cheap at times -- between $50-$100 each) http://www.replicafurniture.com.au/replica-charles-eames-style-bar-stool.html

ideas for a bigger kitchen.. from the look of your plans I'm guessing that hall way wall might be your load bearing wall. my idea would be to extend the wall where your pantry/fridge/WO is to close off that corridor..with a new door that will lead to the laundry. it also gives you scope to knock down the wall between the kitchen and hall way to make way for a bigger kitchen, pantry area. then I would knock down that wall that's housing your fridge and pantry etc to make room for an Island bench..
