3/4" Red Oak Hardwood Floors is what we replaced our laminate with.
Generally: 3/4" Hardwood handles better than laminate:
1. Seasonal fluctuation in temperature (expansion/shrinkage).
2. Water exposure (spilled water, overflow sink/drain/toilet etc).
3. Scratches less easy compared to pre-finished laminates.
4. Sound isolation. Thicker/more solid wood provides better damping.
5. Refinishing. Little or no 'refinish' potential with laminates.
If you have to replace any laminate pieces for whatever reason; and you local supplier is out of the grade/brand that you had put in you're SOL. Whatever you do to replace those pieces or sections is going to look bad. You can more easily replace and match finish true hardwood flooring. In the least, re-finishing (which isn't as big a deal as some here say) does a great job of blending the new/old planks.
Finish is important. The type of finish can determine the type of look your floor has (natural wood, satin gloss, poly warm, and others). However, what most people overlook is that there are also different types of actual finishes. There's Polyeurethane (sp) and a couple different kinds of water based finishes. A commercial venue uses a water based finish called "
Street Shoe" and it's one of the most resilient durable finishes you can apply. It's also the most expensive. Poly's on the other hand are inexpensive; but they don't wear as well. Some of the finishes are also prone to fading in areas of consistent sunlight whereas some types of finish are actually guarranteed not to fade.
I'm out of time at the moment, but google "street shoe" and hardwood floor finishes. There's good info to know about finishing, especially if spending that kind of dough to put in hardwood floors.
The pics on the following page are don't do justice to the floor we had put in and we no longer own the house so I can't get updated pics. But, our floor has a "Street Shoe" finish and it is highly resistent to scratching; much moreso than the laminates we had and many of the floors that we sampled.
