We just moved into this house and there is carpet in my sewing room. However, it's such a large room that we don't have the money to change it to tile right now. That is a future plan, because we will not only have to change the carpeted area, but also the old tile in the walkway next to it, the kitchen, and the eating area (all connected to each other, so quite a big space).
We did change the hallway and the master bath from carpet to tile.
