I've been in the flooring game selling carpets timber vinyl and ceramic tiles for 35 years, you are not the only one with this problem. The best solution is to remove the tiles but this is a big job but gives you 100% job but you probably know this. Bamboo flooring is good but please do your research on this because they are made two different ways Cold press and Hot press and the prices very from $30 - $60 also you will need to ask for the VOC certificate for things like formaldehyde. A lot of the cheaper suppliers do not have there's tested. The other thing that the industry is having but they want tell you is the bamboo is expanding and contracting a lot more in the Australian climate. Sorry to put a damper on bamboo. There is a newer floating floor on the market it has been around for about 7 years it is vinyl 4.5mm to 6mm thick its is good for going over tiles as it does not create to-much of a step and other issues in doors and kitchen

Seriously you need to check out the Kerlite cladding. No need to sand, the variety is huge even wood look. All you need to do is put on a thicker screed. As I said you do need a tiler that has laid it before. Once it's down, it will never break. Google it, the range is amazing and really beautiful. I did ask the tiler about using it over slate and he said not a problem. Got mine from tile expo.

Hi Kirsty, could you please advise the colour of your vanity and whether it is a custom made one and if not, could you let me know its name and where you bought it. Also, what is the colour of your floors tiles and where did you get them from. (I have come to the conclusion that charcoal/dark grey tile plus a much lighter grey tile plus white on some walls plus a timber vanity or timber accessories in bathroom , plus white (or close to it) below sink counter top is the way to go for a beautiful bathroom. The trick is figuring out exactly what proportion of each colour to use and where to put them for each particular layout.

personally I like a home that has a similar style on the inside as the outside, it just makes sense to me. In the past I thought building extensions should be similar in style as to the original, however after reading (and commenting on) Houzz posts I am now coming round to the idea of a modern extension on an older building. But having a kitchen and bathroom in different styles, that might just be to your taste and that is fine - there is nothing wrong with a building reflecting the personality of the owner!
