For years, living the life aquatic meant forgoing hot showers and spacious water closets. Well not any more! Today's boats are coming equipped with the latest in high-tech bathroom designs. The combination shower/sink that has long been a staple to boaters has made advances in functionality and design. Very popular today are stowaway handheld showers, available in polished chrome or nickel. Nautical toilets have also come a long way in form and function. They are now readily available in full sizes with a low-flow water-control design that is easy on the environment.
