I work for a construction company and we used bamboo in a clients house last year, we were sceptical about it but did some tests (sat a plank of it in water for a few weeks lol) and it held up well; didnt change its shape or anything. We used "HIE 15mm strand woven pre finished bamboo solid T&G floor" for 236.68 including GST cost around $18,000. Looked gorgeous too

Not sure if any of that is useful information but hope it helps hehe
