Once the paint was done we moved quickly to install the flooring. We were looking for a few things; something attractive, affordable, durable, and would give strength to the nearly 60 year old sub-floor. While we replaced the rotten sections of the sub-floor; extra strength in an old trailer is always a plus. Chris recommended UV coated plywood. It is plywood that has been cured using UV light/rays and creates a much more durable finish than could be achieved otherwise. It also gives a very smooth surface to walk on. You can see a piece of it above. We used 1/2 inch Birch, and probably went through an entire stack to find the 5 most attractive sheets they had.
Before we installed it, I thought it would help out in the winter to put a 1/4 in. polystyrene board underneath the plywood to create a thermal break between the potentially freezing air underneath the trailer and my toes:
The foam board also served as a good template to be cut for some of the tricky corners. The install actually went very quickly, and really warmed the interior up quite well. We attached it using stainless steel screws which gave it a nice industrial feel. After living in it a few weeks now, I can tell you the floor has really held up well. It is nice on the feet and very easy to sweep up. You don’t have to worry about spilling liquids on it at all, which is an added bonus. Check it out:
Remember when I first got it?:
