Lake cottages attract sand, water marks from footprints, and moisture conditions that are highly erratic with the season changes. One needs to have a flooring material that can accommodate a wet dog and sandy visitors without developing marks or warping halfway through July.
A popular flooring choice among lake cottage owners is luxury vinyl plank (LVP), not only because it is water-resistant but also because its composition is more forgiving regarding seasonal changes compared to hardwood floors. If the house remains closed or unconditioned at any point during the season, vinyl is less likely to buckle or split due to high humidity levels.
Tile flooring will remain your best option for "wet" spaces like a mudroom, bathroom, or wherever the wet towels will be left. It is basically bulletproof. You can mop up lake muck in seconds, and you don't have to worry if a wet swimsuit sits on it for three hours.
If you are renting the place out, durability matters more than anything else. Renters usually aren't careful with heavy coolers or dragging luggage across the room. Choosing a floor that is easy to maintain and scratch-resistant is a lot better than spending your weekends obsessing over a high-end finish that is already scuffed.
