Flooring

I have some water damage on my hardwood floor from a few weeks ago when I flooded the bathroom. I've been looking at my options, and have been considering replacing the entire floor. Since I moved in, I always believed that my living room floor is a laminate and never thought anything more of it, and I was planning on going out tomorrow to buy new replacement laminate. However, I looked more closely at the flooring tonight, and it's actually engineered hardwood. It has a top layer of real wood 2 mm thick on top of a 10mm thick backing. It appears that it might be glued to a 1/4" plywood base. It's hard to tell if it's floating or glued down.

I'm definitely not replacing this with laminate, and so now sanding and refinishing the floor might be an option to get rid of the warping. I never liked the colour of the floor anyway, so this might be an opportunity to stain it darker.

This is also an opportunity to get rid of the electric fireplace and replace it with a wall-mounted TV. I already pulled the fireplace out of its enclosure and just need to remove the enclosure and finish the wall behind it. I've attached a picture of the enclosure without the fireplace insert. The wall behind is finished, as is the floor. The enclosure is glued on the inside and caulked on the outside to the wall, so I will need to fill any damage to the wall from removing it, and then paint the wall the beige colour seen around the enclosure. I still have some paint left from when I painted the apartment in 2006. Once the fireplace enclosure is removed, I'll gain about 5-6 sqft of space that is presently wasted by something I'm only using as a stand for my stereo.
