About a year ago, we had our 16x21 (foot) family room professionally installed with prefinished hardwood (oak). Total cost was about $3,000 in Connecticut. To clean it, just use a mop with water. To make the room danceable, we removed all furnitures and added a 7-foot wide wall mirror. The mirror is 5-foot high and 1.5 feet above the floor. A local glass company installed it for about $300.
