The new toilets have been designed to become unbearable to sit on after five minutes.

The ‘StandardToilet’ named after the startup company which made it, has been supported by the British Toilet Association (BTA), a group that campaigns for better bathroom facilities in offices and public spaces, The Times reports.

The toilet seat is downward tilted by around 13 degrees to increase strain on the legs, similar to a gentle squat thrust, according to developer Mahabir Gill.

StandardToilet has said that the product has already had interest from local council and motorway service stations for the £150 - £500 toilet.
