We used vinyl (mid range lino-look) in two guest baths. Holding up well after 10 years. We used the cheapest sale box laminate for a vacation rental bath 4 years ago. Holding up well, hasn't warped. Don't know brand name. In the full time rental unit downstairs it chipped in one spot. I stained the spot and varathaned over the chip. Hardly shows. In the other vacation rental my husband put down pressure treated hardwood flooring. It has held up pretty well except along the seam where it hits the shower stall. After 8 years there is a black edge I will be seeing to in about a week. If I had dug out and replaced the caulk at the beginning of the season it would likely have been alright. Because of other things going on at the time it didn't happen. I'll dig out the 1/8" bead of caulk, use some deck wash or other bleaching agent then recaulk and varathane or other finish treatment if needed. The problem stained area extends up to an inch out from the edge of the shower.
Overall I'm surprised how well the cheap laminate has held up. I wanted to redo the fir flooring underneath, but its in pretty poor shape although intact. That will be for the next owner of the house..
