my shed 16 by 20 is on a concrete slab........

far better in so many ways.

And worse in others--- � portability, dampness, worse to stand on for
any length of time, tendency to crack in my neck-of-the-woods �and
initial cost for starters.

wood floors attract occupants moving in, properly laid concrete
sholdnt crack think rebar and relef cuts, lasts literally forever wood
floors even pressure treated sag and rot out.and attract moisture.

concretes initial cost may be a bit more, but after that its free..

a soft rubber mat adds comfort for standing.

frankly the less maintence the better, concrete is maintence free.

and how many have actually moved a larg shed???
