I get it has it's uses for disability etc if you've nowhere else to put one, but am I the only one who finds toilets under the stairs a revolting concept? I find it particularly grim if your understairs cupboard is directly in your living room!!
Downstairs loo in a reasonable place not a problem. But surely most understairs are little more than an unventilated poky cupboard. I just can't see why people think this is an improvement to a home - unless they really need disabled access. Just think it's an odd trend.
