Designers have a difficult time making walk-in tubs look anything but, well, ugly. There are a lot of requirements (like size) that lead to a default solution that seems clunky in an otherwise-nice bathroom space.
This solution by Su Pin Chia works around these issues in a few interesting ways. First, its strong horizontals and divided sections break up the monotony of the megalithic form. Second, when not in use, it is simply much smaller since the sides can remain down rather than up. Finally, the use of two materials – one hard, one soft – make it seem more like two elements than one.
