I did that at my old house and loved loved loved it, even though I am far from tall! Unfortunately our new bathroom (even with chimney removed) will be 1500 x 2100. The loo *has* to go on the 1500 end (cannot relocate the downpipe to the other side), so the bath and basin need to fit on the 2100. The basin I want is 600, so its a 1500 bath for us :(

We currently have a bathroom thats about 1500 square, a separate loo which is 1000 x 600 (will turn into a cupboard) and a cupboard with a chimney in the back. The space is too small to preserve the separate loo, IMO. In 6 months I won't be able to close the door when I use it!
