What do you think would be a good floor covering in my daylight basement? It is a high end house and I don't want any vinyl. I need to use products for a laundry room, bathroom, home office, and media room. I don't want carpet every where. Can you use berber carpet in a slab application? Even though the entire slab is insulated, I am afraid tile might be cold in the winter. I live in the Seattle area. Help.
