I think it was around 30. I used two different colors; a blue 6" border and then a steel gray for the main part of the flooring. I did remove the dinette to make this easier. Count on about 8 hours to do a 28' trailer. The hardest part is making patterns to fit around all the curves, which as you know, are plentiful! Also, doing the bath, which is quite small. I did screw up a few tiles, but I suspect most people do. I really like the FLOR. Have had to pull up an occasional tile due to a messy spill. Just scrub it with dishwashing liquid, hose it off (seriously!) and let dry. Then put back. The tiles join with sticky squares, easily replaced. I'm sure you've already checked that out on their site. I didn't get a pattern or Berber look as I have two dogs and I thought dog hair would be a problem. Have a battery operated Dyson that goes on the road. VERY easy cleaning job vs. the A/S rolled vinyl floor which always looked dirty. Good luck!

I'm interested in your Flor tiles. The look very good. How many tiles did it take for yours? We bought our first Airstream in early fall and have already made a few changes to make it more comfortable for us. When I looked at your profile, I saw you're a member of group I never noticed before, Milit-AIR-y. I'm glad I found that. I retired from the Air Force after 23 years in 2010. My husband is still active duty Navy. He's at 27 years.
