Yeah we've got plenty of floor sockets, they're a special unit though.

They're not waterproof, but you just don't install them in places where they're likely to be soaked with buckets of hot water.

Personally, I don't like them having injured my foot by stubbing my toe on one that had the lid slightly raised up when a plug was inserted.

But, if they're an absolute must i.e. you need power and there are no near-by walls or other alternatives, I guess they're an ok sollution. Just don't stub your toe!
