A few blocks from London's Picadilly Circus, a lavish restaurant fit for Marie Antoinette is tucked inside a discreet white townhouse.

The restaurant, named Sketch, houses some of the world's oddest-shaped toilets — latrines that look like they belong in a sci-fi production, rather than an upscale restaurant.

Each egg-like bathroom pod is taller than a human and contains a single toilet. Sinks are located outside the pod.

The pods' design borrows from a very different product that's already on the market: a sensory deprivation tank. Also known as a float tanks, the devices are most often found in spas, and they're built to be small, soundless, and dark. Though Sketch's pods are vertical rather than horizontal, their shape resembles that of a float chamber.

According to SOMA Magazine, eerie music and futuristic sounds play inside the pods, which also feature color-changing LED lighting — a feature many float tanks also share.

Personally, I'd be a little hesitant to lock myself into one of the tiny pods, even as someone who's not claustrophobic.

But there are plenty of weird bathrooms to try out around the world — you could always use the facilities 650 under the ground, or inside an enormous barrel.
