We are also doing some cheap reno's as we don't will be leaving here in a few years. So we are doing things up easiest way we can to make a difference etc. Can't help with the bathroom, but in our hallway, nursery & soon in our kitchen we used cheap version of floating floorboards that "click together". We got them on sale for less than $25per square metre. Our floorboards under the lino were too ruined. The best thing about it is it's cheaper, & the "click together" style of them means you put the floor in yourself, saving you the $$$ of paying someone to do it for you. We did a large hallway & a nursery for less around $800. I think that's pretty good for 2 rooms considering it was about $650 just for the carpet in DS room. I would think you would be able to get it from bunnings cheap also, we got ours at a flooring shop.
