Having had two MAJOR floods, I went with wall-to-wall. But the carpet I picked is synthetic and has what's known as "action backing." IF I flood again, I can pull up the carpet and dry it out and have it put back down and re-stretched. I was originally looking at carpet at 3 times the price. Im just as happy with the pattern and I can replace it twice and still come out even.
Fortunately, BOTH floods happened BEFORE I got the carpet down, but I DEFINIETLY took flooding into consideration. I ordered a theater-type carpet and a buddy of mine installed it. You can probably find a carpet that would work in your situation for not much more than you are paying for tiles. Although, after that deal on the chairs and cabinets, maybe not!
It's a chance you take in a basement with water "issues." I put down a laminate in half of my room. But it was a cheap one, just in case....you know what happens. I may have to replace the laminate, but I'm 99% sure I can save the carpet. If the tiles are cheap enough and you can install yourself, maybe it's worth it. Put them down and hopefully, you'll never have another flood. That's what I'm hoping.
I guess I'm just saying to check the glue..how "permanate" is it? Can they be pulled up after months/years?
Personally, I'm partial to the reds and the stripe. I'm not seeing the two black/grays on the left or the one on the far right working.
