When we had the bathroom in our 102-year-old bungalow refloored, the remodeler said the best thing to use "...is high-end vinyl. These houses move." So we bought the second-most-expensive Congoleum, and six years later, it looks brand new.

Some people are touting old-fashioned linoleum as a 'greener' choice, but linoleum:

is not really waterproof
needs acrylic sealing (per professional flooring site)
costs more
may be easily dented and damaged.
possibly does not cope well with a house that flexes in the wind.

I'm tired of people who talk about the 'greenness' of products and hide the disadvantages from the customer.

Example: consumer reports rated washing machines environmentally by figuring how little soap and water they used. didn't mention which ones wrinkled your clothes to heck, causing the customer extra work and electricity.
