Re: Installing wood floor around curved fireplace hearth
1 - see if there is a companion molding for your flooring that is flexible enough to make the curve. Specifically, you're looking for a wood to door threshold molding, which is basically rabbited on one side to accept the flooring and square on the other, the top will be rounded to blend into the floor.
2 - Choose a molding from the trim and molding aisle that will make the bend and finish it to match the floor.
3 - Find a cabinet shop and have them make up a segmented molding to match the curve. You can make your own if you have the tools and skill, I'm assuming you don't, however, hence your question.
