Watur is a door made out of water. Or a fountain that looks like a door. Whichever you prefer.
The Watur is billed as "functional," and by that I take it they mean it can open and close. The promo copy for this is...er...well...here, you decide: "A functional door formed by constantly falling water which pushes for a redefinition of boundaries and obstacles by forcing one to choose to be denied or refused access." Right. Exactly. Could not have said it better. Whatever it means.
The Watur is a standard door width, so you can put it pretty much wherever a normal door goes. (I'm assuming the water is self contained, but I could be wrong. I'm also assuming it needs to be plugged in.) The ideal use for the door, we're told, is for gardens, bath houses, pool houses, and spas. The normal model runs $2,000, but a custom size will cost more.
