Wide pine. Definitely. Warm and cozy.

I'd probably choose wood look tile...maybe something like this? Get pro advice on best grout to use.

Do you think the subfloor is suitable for tile?

oh, good point!

Yes, crl, that's what my husband was wondering. I'd put an area rug over it, but tile is also so hard and cold. We have lots in our new house but also have radiant heat in the floor.

What do others think of wide pine? Would it warp? Pretty damp around here sometimes.

Personally I wouldn't go for wood in the moisture and temperature extremes of an unheated cabin, particularly wide plank.

Although floating luxury vinyl plank may not be recommended by manufacturer for unheated homes due to shrinkage, I'd be tempted to try it.

I live on Cape Cod and have wide pine floors. They are gorgeous, warm, and in a cottage, the more worn they get, the more charm they have. Obviously you want to seal them with Waterlox. My floors have absolutely no warping issues, and this house didn't even have AC until last year.

Does anyone have experience with cork in a similar situation?

Tibbrix, do you heat your cottage in the winter? That would make quite a different IMO.

If this is just going to be a cabin you visit on occassion and want something inexpensive, why not just use plywood? Here are some creative ways it can be used and I think it's a great inexpensive solution.

Robo, this is my home. It is heated, but the heat is turned off at night, and in the other wing (also with pine floors) I only turn it on when the temp outside is 20 or lower, to keep pipes from freezing.

The key to wood is to give it room to expand and contract and to protect it from water. But wood is what people used long before other materials were even invented. I happen to think wood is very forgiving. It gets better with age and wear, rustic handles mars very well, and if you don't like a mar, you just sand it out and reseal that little area.

I think pine floors are pretty uncommon in the PNW. More common in older homes are fir and oak; oak is still very popular, fir (except for original floors) is not seen much. I would think oak would work; after all, they make boats and ships from it.

I believe thin strip oak is used in unheated cabins up here in Canada. Something like 2-2.5" maybe. When I was investigating for myself I saw some reports of cupping and some that love their 30-50 year old wood floors. (We ended up with a place that must be heated year round so I didn't end up needing that kind of flooring).
