The hardwood area under my table measures 86"x50.5". I don't believe all Gold Crowns have the same dimensions, so make sure you get the right specs before having the flooring installed. I sent Brunswick an email and they provided the dimensions. I'm glad they were accurate, because I had the flooring installed before the table was delivered.
This is not snap-together flooring. It is tongue and groove and the pieces are glued together and glued to the floor, which received a lot of prep work before the wood was glued down. I would not use a floating floor, but some seem to think that's okay.
I assume your basement has a concrete floor. Is that right? The floor under my table is wood, so there were supports added under the floor: large beams running under the joists from foot to head, directly under the feet. From those beams, posts at the foot locations run down to bedrock. Couldn't get a more solid wood floor.
Good luck,
Howard
