Koh Samui - living seven meters from the ocean

Well if this 'aint another paradise - I don't know what is! Cute island and we are litary living 7 meters (21 feet) from the ocean. Well we are not under the waves since we have a coral reef outside our lagune.  Fantastic, very simple with a shower like a nice drizzle... how am I going to wash my hair here..? Great challenges to have :-) We'll stay here another night.
