On the off chance you're thinking about a new bathroom, I thought you'd like to see/hear about this lovely invention.
It's the Yin Yang Bathtub and apparently ideal for couples "who feel like sharing their bathtub without actually sharing it". It has sound waves and color light (so it's not just pink and blue bubble bath) and massages you into the bargain. And what a bargain it is - $55,000 or 33,000 quid. I'm sure there's a hefty installation fee on top of that.
I don't know about you but if I'm having a bath I don't feel like sharing it at all. I don't want anyone trying to talk to me under the door, shouting up the stairs asking me where the dog leash/car-keys/phone is, or otherwise interrupting my precious "me" time. Ideally I'd have a glass of wine and read my book, but who am I kidding? If I take a bath instead of a shower it's still less than a five minute job and never involves mood lighting.
I am wondering however, if this concept extends to co-sleeping. I mean for those "who feel like sharing their bed without actually sharing it".
