IMO in a bedroom for sure save the hassle of finishing on site

Known color and appearance. Sanding on site is horrible. The dust, very fine powdery dust that takes forever to get rid of.

That is helpful and reflects what I have read re: on-sight sanding; wonder about cost comparisons, too? Also , Jan, how do you think the results compare to other hardwood options? Although efficiency is always a consideration now, long-term the results of the project will be what lasts. We would like to eventually use the same wood in other rooms throughout this farmhouse as we replace other carpeted areas. There is already red-oak in a connecting hallway and another living area. I appreciate any feedback on this.

There are advantages to BOTH pre finished and sand on site. The latter is always available, allowing a more piecemeal install over time.

The pre finished CAN be discontinued, and then you're stuck.

Red oak on site depends do you like It? Do you want more of it? Or would you prefer something else?

Good thoughts and take-away information that I will use, thank you all here. Ideally I would want the same floors throughout all of the wood-floor areas, replacing what was put down 20 years ago, for the beauty and over-all continuity in the house. I had not thought about the possibility of what we use today in our bedroom being discontinued next year when we may be moving forward into the rest of the house, meaning we could end up with three, not two, kinds of wooden floors! Jan, gratitude for this!
