The block, on Clarence Esplanade, Southsea, Hampshire, closed for the major refurbishment last November.

A council spokesman said he hoped the loos, now open 24 hours, would be seen as a "flagship" block of excellence.

He said he hoped the changing musical styles would make a visit there an enjoyable part of a seafront trip.

"Police were closely involved in the design of the building to make the toilets as clean and safe an environment as possible," the spokesman said.
