It should also be acknowledged that in many, many properties there's absolutely no need to provide bottled water.
In those cases where it does make sense, or if it is being offered as a luxury (some people prefer mineral water, some perfer sparkling) then make sure that (i) it genuinely is of good quality and (ii) it hasn't travelled thousands of kilometres.
There is nothing luxurious about serving Norwegian water in China, Italian water in North America or Fijian water anywhere that isn't Fiji. As for Bonaqua, Dasani, Aquafina etc.: just say no.
Even with sparkling water, it doesn't need to be commercially packaged shipped in from somewhere. I recall on a past stay where the hotel provided glass bottles every night at turndown filled with our choice of flat water or sparkling water, so presumably the hotel used a machine to add the carbonation. They were reusable glass bottles with a flip up wire capping mechanism. Both were chilled before being delivered to the room. It would have been a Fairmont, but I can't recall exactly which hotel. The only problem was figuring out which bottle was which, since my wife likes sparkling water and I prefer flat, and the glass bottles looked the same since there were no labels. Had to open one and listen for the pop to figure out sparkling from flat.
