But plywood’s softer surface has a tendency to chip and dent, making the final application of a hard top coating vital to the success of your floor. 2 Plywood floors are suitable for any room where you’d otherwise install hardwood, though kitchens and bathrooms are less desirable since frequent water spills are likely. Basements are not recommended for plywood flooring because they’re typically a bit damp, and a concrete floor can transfer moisture from the soil to the plywood, which could cause it to delaminate and swell over time. 3 A 1½-in thick, 4-foot by 8-foot sheet of CDX plywood (the kind used in subflooring) sells for around $15.
