Farmhouse Washer & Dryer Pedestals

Build two mini floor systems from the 2x4s with glue and 3" screws (or 1-1/2" pocket holes with 2-1/2" pocket screws): rims front and back, joists between. The TOP floor gets every joist — it carries two running machines. The bottom floor can skip its center joists; laundry baskets don't earn them.

Square each frame by matching diagonals before the glue sets.

Glue and screw the 3/4" decking to each frame. Glue matters here — a glued deck turns the frame into a torsion box, and torsional stiffness is exactly what fights a shaking washer.

Screw an angle bracket into each inside corner of the top floor with the 2" screws. The source builder added these because an overloaded machine literally walks — the brackets are cheap and this is the step where they're easy. Don't skip them because your current washer is polite; your next one may not be.

Flip the top floor deck-down and screw a 4x4 post into each corner through the framing with 3" screws. Pilot-drill and add a few screws driven at an angle into the post from the frame faces — angled screws resist the racking that straight-down screws allow.

Set the post assembly onto the bottom floor and screw UP through the bottom deck into each post — at least three 3" screws per leg.

Now level the whole pedestal in place and shim any floor gap; laundry slabs slope toward the drain, and the machine's feet can only correct so much.

Miter the base cap moulding around each post with 1" brads — the ten-minute step that turns framing lumber into furniture. Sand and paint.

Set the machines, run a spin cycle with a full load, and watch. Any shimmy: skin the back in 3/4" scrap (glue + 3" screws every 4" into posts and framing — it becomes a shear panel) and/or screw the frame to wall studs. With kids in the house, do the stud attachment regardless.
