Vinyl is idiot proof to install. Source: I managed to do our 2nd bathroom.
I used a vinyl/cork product which allegedly does well in wet environments (as I said, bathroom).
We used Wicanders Hydrocork similar to this one
Wicanders Hydrocork but with a slightly different finish.
It's easy enough to lay out, very comfortable to walk on even barefoot, and they say it's sturdy and waterproof. We paid roughly €50 per square meter tax included though (for comparison our click parquet was roughly €30 per square meter) so it's not the cheap option at all.
