We,ve actually had two sets of guests in our bathroom when we've had guests in all the other rooms, and they were very interested in the grey water recycling. Everything is working well and its nice to try out the different bath products -great for us and for the environment as well.I've always wanted a nice blue and white chamber pot -for display purposes only of course - and was delighted to find a Ringtons one in a North Yorkshire antique shop, as we do have Ringtons -teas, coffees and other products in every room as examples of local produce -also have an art nouveau tin with choccies in in the bathroom incidently. Ringtons was started in  the North East in 1907 and our bathroom is designed in an Edwardian style, so its very in keeping.
