To celebrate World Toilet Day, here are Dezeen's favourite unusual toilets
As it's World Toilet Day, here's a selection of our favourite toilets from the Dezeen archives, including a straw-bale urinal for rock festivals and a pissoir that straps to a tree.

The annual World Toilet Day has a serious purpose: to raise awareness of sanitation and draw attention to the 2.5 billion people who do not have access to a clean and safe toilet.

However most of the toilets we've published are designed for the convenience of people in the developed world, including a surprising number of solutions for people attending open-air concerts. There's even a portable urinal for festival-going girls.

Other designer WCs on Dezeen include a toilet called Mrs Hudson by Ukrainian architects 2-B-2 and one with an integrated wash basin, where waste water from the sink is used to fill the toilet cistern.

We've also featured a few unusual toilet blocks, such as the new golden public toilet in Wembley that aims to "inspire confidence" and "pride in a place".

At the other end of the scale there's a public toilet that's inspired by the facility's location in what was once a red-light district and even a pair of cubicles that look like headless dinosaurs.
