At Pottery House our Green Tourism Award and our ecologically safe practises are an important aspect of our business.
So recently we replaced all the shower heads in the house with Mira Eco Shower Heads. They work by aerating the water so you get the same volume and powerful water output, but they use up to 75% less water (and therefore the energy required to heat the water).
We trialed one of these is these in our own shower first and thought it was great, really didn't notice much difference, so now we've replaced all the shower heads in the guest en-suites too.
