Lights, shower, action

SIR – John Rowlands (Letters, April 23) would like to buy the kind of shower featured in films, which instantly achieves the perfect temperature.

Such showers are not available, as far as I know, but Mr Rowlands may wish to try an LED shower head, whose colour changes with the temperature of the water.

He could then step into the shower knowing for sure that the stage was set for his Hollywood moment. Virginia Hudson Southampton SIR – Mr Rowlands should take care when choosing a Hollywood-style shower. A notorious 1960 model came with a knife-wielding murderer and scary slasher music.

Hopefully modern versions are more user-friendly. John Walliker Dadlington, Leicestershire
