On the smallest shower in the world

So far, the one in Carlisle is winning but the Edinburgh B&B is running very close behind. I reckon the shower base is about 80mm square. A tall person would have to open the door and get out to pick up the soap! Mind your elbows! They do have plenty of hot water, though, using those instant electric devices that deliver fast, endless hotwater, as advertised. The units have options to choose the flow rate you require, I can't see anyone wanting less than full flow, because even that is less than gushing!
