With a bit of work, I've managed to find a supplier used by our builder who has stock of the original vanity and basin!

Ok so long as floor not white

HI Renae, I like your colour choice black & white, I went all white in my renovations of kitchen & bathroom and just by adding a bright coloured fruit bowl, vase, pot plant and a small painting in the kitchen made the kitchen look fresh whilst in the bathroom I just added bright towels bath mat. I changed the colours in winter to warm colours and cooler colours in the summer both kitchen and bathroom. These are simple and cheap things to change a look whilst if you go for timber it can date quickly and timber absorbs moisture so it has to be looked after (time consuming and $) looking forward to seeing your finished renovations.

have you personally inspected the property to clarify the available space as the real estate photos show that bed 3 is already being used for the living area so the property is really only two bedrooms plus open plan living dining kitchen and attempting to add an upstairs powder room would mean having the toilet open into the kitchen living area ..it may be possible to install a tiny powder room above the stairs (say $10-$20,000... if you could gain Council approval to do it) but another property with an existing upstairs bathroom would be more comfortable for yourself as well as your guests
