I just did my whole house. Got ceramic tile that looks just like wood, even has a texture that feels like wood. And carpet, really high quality stuff with a memory foam pad in the master bedroom, family and living room are carpeted with tile borders. Stairs are carpeted on the step tops only, but upstairs hallway and two of the bedrooms are fully carpeted, while the third upstairs bedroom is actual hardwood. So my house has maybe 60/40 tile to carpet ratio. Carpet alone was $10k.
Master bathroom floor is heated under the tile. It's cheap to do if you're ripping up the existing flooring anyway, it only added about $1100 to the cost.
