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

Here's a video of an area of water damaged bamboo being removed and replaced Joyzzz. Maybe you'll consider replacing the area in front of your fridge. Like you I also have bamboo in the kitchen (and pot plants throughout the house), but haven't had any issues with spills marking the floor. It's a shame there's so much variation in the manufacturing process resulting in some floors tolerating spills and others not at all. I do have a damaged board though thanks to a guest leaving a tap running causing an overflow...that I wasn't told about until days later, grrr. Fortunately the damage is in a shadowed corner and the sealer is still intact, so it isn't noticeable, just a wrinkled surface to the touch. Which is lucky, because our home is earth-covered and there is nowhere for water to drain out of the sub-floor as we "tanked" it with a sealer to ensure no moisture can make its way in. That board sat there in a puddle for days! I still wonder why only one board suffered damage, very strange...

What a great job you did. So good that you just went with white. The concrete floor tile on wall behind the vanity would have been too busy after now having seen the finished product.

There is a good reason why tradesmen prefer to quote with reputable brands. A large component of your cost will be the painter's labour. If you use a cheap, low quality paint, that has poor coverage , inconsistant colour from tin to tin, starts to bubble, starts to peel, etc, are you going to seek compensation from the cheap paint company (who probably don't have an office in Australia, and don't back their product), or go back to your painter, who will only blame the crappy paint you specified? Cheap materials usually lead to a more expensive job as they often need to be reworked or redone, and it is the labour cost. If I was your painter and you insisted on using crappy paint I would charge a premium to cover my costs to get the job right. Same goes with tiles, tiles are relatively cheap, but it is the skilled labour that costs. A good tiler can't do a great job working with tiles that are inconsistant in flatness, size, thickness and brittleness. You get what you pay for, but the labour still costs.
