Interior Design Show highlights: The Ultimate Bathroom

I always look forward to the concept spaces at the Interior Design Show. And with this year's theme of the "Ultimate", I knew we were in for a luxe treat!

The spaces started with Arren Williams' "Ultimate Bathroom", inspired by Calvin Klein's Euphoria.

The "his" portion, above, also included a shower with black textured tiles and even a black toilet and urinal!

This photo doesn't do it justice - the flash is not kind in dark spaces - but here's the meditation and relaxation area, with chairs by textile designer Bev Hinsey.

I loved this spooky yet stylish tree in the space, too, especially those flickering bulbs!

And the "hers" side. In my mind, it doesn't get much more luxurious than a soaker tub!

One of the dressing areas by the tub. I, of course, was inclined to adore the space as soon as I stepped foot in it - the palette of chrome, black, grey and purple just happens to be my current favourite. Plus, the combo has always, in my mind, conveyed the perfect mix of luxury and gothic vibes.

So, what do you think - is this the Ultimate bathroom?
