I have not noticed it myself, but if I was a hotel owner in my city, with our outrageous water rates, I think that is exactly what I would do. I would cut costs on water by using environmentally friendly fixtures. I would also try to get a tax credit for doing so.

The city might even have environmental initiatives placed on hotels to get them to cut back on water usage, either by penalties, or by incentives.

Either way, if I was a hotel owner, I would make full use of those fixtures as water costs are significant, and the majority of guests either don't seem to mind, or they put up with it.

I suppose its like leg room on planes, or paying to check bags. Its a revenue generator by the business, and either it works and it doesn't impact the number of guests, or it doesn't work and people leave your hotel in droves.

I personally have gone all in on low flow products. Shower heads, new toilets, water efficient dishwasher, water efficient washing machine. My water usage is absurdly low and my water bill is also pretty low. I have really not found a negative in doing so. But unfortunately, it impacts you more negatively. But I suppose its the nature of revenue management. I suppose you could fill the tub up with water and use a bucket, but I don't think that would be a very pleasant shower.
