An SWBuildings pressure treated floor offers a simple and sturdy base for your new shed. The base is made from pressure treated 2x4's and covered with 5/8" floor sheathing, for a total of approximately 4-1/8" overall height.
 
A layer of gravel / crushed stone / HPB is highly recommended to go under the floor base for drainage and stability.
 
Please select the floor base size corresponding with your shed size.
 
Note: Floor bases are typically not required if your shed is being placed on a concrete pad or patio stone base.
