Ten outstanding loos for World Toilet Day Also read: Amazing lavatory locations: the world's best loos with views Mount McKinley Toilet, Alaska, United States Perched 14,200 feet up on Alaska's Mount McKinley, this stands on its own surrounded by nothing more than three wooden slabs and plenty of ice and snow. Hiking here is not easy, and there's still more than 6,000 feet to go from here to reach McKinley's summit. Largely open to the elements, this lavatory offers a novel experience and the view of Mt Foraker to help you forget about subzero temperatures. Hundertwasser Public Toilets, Kawakawa, New Zealand Some visitors stop here not for a loo stop, but just to take pictures. Located along State Highway 1 in the rural area of Kawakawa in the North Island, these public lavatories were designed by late artist-architect Frederick Hundertwasser. Built in the late 1990s, these bathrooms feature bricks from a former Bank of New Zealand building, a living tree, tile mosaics, curvy columns and walls embedded with glass bottles. The facility also has a grass roof. Pop-Up toilets, Europe Places like London and Amsterdam are curbing public urination with a futuristic solution - toilets that emerge from the ground during the nighttime hours then retract and disappear during the day. A company called Urilift is producing these cylindrical lavatories. They've started with walk-in urinals and have now moved on to pop-up loos with doors for the ladies. Other types of portable urinals have also been popping up across Europe for more than a decade. Daimaru Department Store, Tokyo, Japan From the people who brought us Toto, one of the world's high-end toilet brands, come the commodes of the Daimaru Department Store. The public bathrooms here are outfitted with, yes, Toto toilets. The shopping destination has 13 floors, each of which has its own bathroom designed to match the floor's atmosphere. These aren't your standard toilets, though: they have everything from heated seats to sound effects (to mask typical bathroom noises), and feature a self-cleaning mechanism complete with temperature-controlled water. Public toilet, Chongqing, China Widely known as the largest public restroom in the world, this facility in Chongqing is impressive in numbers alone: four stories of about 1000 toilets spread across more than 32,000 square feet. Now, that's a big bathroom. But the intrigue doesn't stop there - the toilets here range in design from curvy women to open crocodile mouths. The bathroom even features one group of open-air stalls and entertainment options such as calming music and TV shows. Glass lavatories at Downtown Square, Sulphur Springs, Texas, United States In 2012, Sulphur Springs introduced a pair of glass bathrooms in its downtown square. From the outside, these appear to be a mirrored cube, but step inside and you'll discover these walls are made of a one-way glass that allows those on the inside to look out, giving you the feeling you're doing your business in front of anyone and everyone who passes by. The walls work, in part, through an imbalance of light - the light outside must be brighter than it is inside, so LED lights have been set up outside to keep the magic alive at night. The toilets came as part of a general revamp of Sulphur Springs" downtown area and they were inspired by an installation in Switzerland by the artist Monica Bonivicini. Chung Yo department store lavatories, Taichung City, Taiwan The lavatories may not be the main draw of these elaborate themed bathrooms at the Chung Yo department store in Taiwan, where there's a Coca-Cola bathroom, a "Wizard of Oz" bathroom, a secret garden-themed lavatory and a "Finding Nemo" loo. But the bathroom that really gets people talking is a men's room that is much more than just a place to pee. This bar-bathroom combo features refrigerators stocked with Heineken for those who'd like to take a leak and a swig of beer at the same time. Erm, cheers. Rothesay's Victorian toilets, Isle of Bute, Scotland The men's bathroom on Rothesay Pier was commissioned by Rothesay Harbour Trust in 1899. Retaining its Victorian-era charm, the bathroom is covered in elaborate ceramic tile work and features white enamel urinals topped with marble - 14 of them line the walls and six more act as a centrepiece of sorts, circling a stand in the middle of the room. The crest of the Royal Burgh of Rothesay sits at the restroom entrance. Much of the equipment, which originally came from Twyfords Ltd. Glasgow, is still here. It was restored in the 1990s, when showers, women's toilets, as well as facilities that cater to children and people with disabilities were added. Urquiza Public Toilets, Rosario, Argentina Situated within Urquiza, a public park in Rosario, these toilets are part of a multi-use facility featuring a sitting area and playground. The toilets, underneath a busy street, are reached by ramp or staircase. It's an extension of the Espacio Once bar, making it a one-stop-shop for both beverages and bathroom breaks. Sustainability was key to the designs by the architect Diego Jobell. These lavatories feature a green, grass-covered roof, cement surfaces that are easy to wash and galvanised sheet iron doors to deter vandals.
