6 foot is available in several lines of regular vinyl as well. Cuts down on waste in smaller areas like bathrooms. I'd have a professional come out and give you estimates on sheet goods versus planks or tiles. Planks/Tiles can save you on materials but often requires more extensive subfloor prep, so they may not be that much cheaper if any. Try to find a reputable store or installer to come out and look at it. Hopefully you can find a few that give free estimates.
