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...

I work in tiles and a trick you can use is to lay the tile horizontally on the 'narrow wall'. This gives an optical illusion that the room is wider. These tiles at around $50 each can certainly add up so a wise use would be to use as high impact. In the ensuite use them behind the bath for the whole wall. Use white wall tiles for the rest of the walls. If you want to add more colour, tile the spa box in an colour tile that exactly matches the blue or grey from the pattern tile, use a matching grey tile on the floor instead of white. Or use the pattern tile behind the spar, make the rest of the room white and add a matching grey vanity. It's a lovely tile but may become a bit gaudy if you have a bit here there and every where. Again with the main you will probably not get an exact match with the outer room timber floor and it could look like you tried to match it and couldn't better to go for a complete contrast. Use the same tricks as the spa bathroom and don't forget matching blue towels for a bit o colour. Hope this helps.

I will be the loan naysayer and go: Vinyl Plank timber pattern tiles. I did these in my kitchen and they helped make the room. Used Karndean, but any European brand should be fine (avoid American and assume they are using American or worse if they don't say the country of origin). http://www.karndean.com/en-au/floors/landing-pages/new-looselay-longboard?gclid=CjwKCAjwspHaBRBFEiwA0eM3kQ7eEFPH5FlK2IwV3o7ZsbbmJ19srG0OM_tWK5dhPMNyDdwxGPUr4BoCoYcQAvD_BwE Caveats: Ground must be FLAT. 100% flat, ruler FLAT. If not you will have to level. If flat, you can lay them yourself. Our floor had to be levelled and it was tough. still got a few high patches and gaps because of that. However I have done it on a concrete surface myself since and it's beautiful. Benefits: Nice and soft on the foot. (less ankle pain) single tile replacement. Looks fantastic. No PVC glue fume issues and fairly resilient. Do be wary though of metal chair legs scraping the floor. Waterproof! when installed right with no gaps! (why I would choose them in a kitchen over timber or Eeek carpet!.... Yes previous owner installed shagpile carpet in the kitchen).

We did think of pulling up some tiles from elsewhere, but they are stuck way too well and would certainly break. Everything in this place is built to withstand a massive tornado, or maybe a bomb blast! We think the builder had shares in the company that made Sikaflex! And no, just using contrast on the threshold won't do it, sadly. I do think we'll have to cut out some good tiles to extend the feature somehow so it doesn't look odd.
