The old carpet in our sunroom has seen better days: it's worn thin in spots and its dark blue color (which looks like something you'd find in an office building as opposed to a relaxing sunroom) has faded. I had hoped to replace it with tile, but we simply don't have the floor height to do this and still allow the doors swinging into the room to function. Then an idea I liked even better hit me: carpeting the room with wall-to-wall sisal or seagrass:
Both of the sunrooms pictured here are examples of what that could look like. I love the casual, indoor-outdoor feel of the material, and think it's perfectly suitable for a sunroom. While I've more commonly seen woven grasses used as rugs, there are broadloom varieties available that are installed wall-to-wall.
What do you think about installing woven grass as a floor covering in the sunroom?
