Sun tubes are still seen as a relatively new form of rooflight or skylight, but in actual fact, they’ve been around for some time. That said, they are changing the face of development, especially with regards to small bathrooms and en-suites. With a sun tube, the light is channelled down from outside the house into a small confined space, giving that area nice light when say ten or fifteen years ago, only a light bulb would have provided any light to the room. Sun tubes are obviously easier to install on new builds than older buildings, but with both, it’s a good possibility. If you have a room that’s terribly dark and you’re going through light bulbs like no tomorrow, then perhaps a sun tube is the ideal long-term solution. They’re extremely effective and many homeowners are surprised at how much light they send into the room.
