Like a “Florida room,” a solarium is often used as just another name for a sunroom. But this style of sunroom is made almost entirely out of glass so as to let in a maximum amount of light. These can also refer to artificial tanning beds, but a sunroom solarium is a great way to tan naturally while still having some protection from the other elements. It’s also a great way to add plants and flowers to your home that love lots of sunlight. A different kind of solarium is an open-air terrace built on top of a traditional sunroom or other home addition.
