We've just bought a four year old home with an unfinished basement. The basement has underfloor heating under concrete. What is the best flooring to put on top? The rooms will be an office, guest bedroom, bathroom, family room and bathroom. We're thinking carpet for guest bed and family room, ceramic for bathroom and an engineered hardwood or laminate for office, and hallway. Will this cause us any problems? We are not planning on putting in a subfloor. We are new to home new build stuff and to this site. Thanks.
