We did our bathroom only last year and it was a total refit. We gutted it ourselves to save heaps of money so we got to knock out walls, ceiling and get up all the old floor tiles. We had bought the new bath, vanity, toilet and some wall tiles from bunnings and the floor tiles from a specialist place. To have it all put in and new walls and waterproofed cost us all up about $10k. We now have to do our kitchen as it is over 40 years old and falling apart. Not looking forward to that.
