Highlands Motorsport Park, Cromwell: Inside 'Loo with a View', New Zealand's craziest toilet

I've stepped inside one of the most unusual places I've ever seen. I'm in a row of instrumental urinals. One is a drum, another a trumpet and the last a bass violin. When you use it, it starts playing music. Things get seriously interesting (and weird) when three men are using them at the same time. It could be the world's most unusual symphony.

I'm in Cromwell, at Highlands Motorsport Park, which is a world-class racetrack created by Tony Quinn, a Scottish-Australian-Kiwi entrepreneur. As the park's website explains, he "also happens to have a thing for toilets. We came up with a lot of different ideas about what we could do with the toilets, and Loo with a View floated to the top." Unofficially, it's known as Cromwell's No.2 attraction.

The bathroom attendant, Riza Valentin, gave us a tour of this porcelain palace, and the first thing you notice is every loo has a view – as the name suggests. Some have floor-to-ceiling windows looking over the racetrack, and thanks to one-way glass, your business stays, well, your business.

Valentin shows us around the musical urinals with a large squirter bottle in hand (to simulate the real thing). She also explained they work if you pour beer in them, but not water.

She points to an enormous caricature-like head of Donald Trump, with its mouth wide open, and sprays the bottle in its mouth. A Donald Trump-like voice shoots back, "This is the very best in New Zealand, tremendous". I can only imagine how off-putting that would be using it.

Next, we head to a line of instrumental urinals. Valentin rapidly squirts her bottle into the bass, saxophone, and drums. An unusual symphony begins to float through the toilets, with the Trump urinal continuing to randomly shout messages like "welcome to my wall." It is hilarious. And on the extreme end of unusual.

"Imagine when three men are peeing at the same time, we have the urinal band," Valentin says with a giggle.
