If you purchase unfinished cabinets, finish them before
installing.
1. Build the wooden frame pedestal using 2x4 lumber and 2 1/2" wood screws (for additional height use 2x6 lumber ). The
frame should be the same width as the window seat area and the same depth as the bottom of the cabinet minus the doors and
1/4" for the toekick. Place a center support in the middle of the frame.
2. Slide the frame flat into the seat area and make sure the frame is level. If it is not, use wood shims to level it.
3. Anchor the sides and back of the frame to the wall studs.
4. Center the cabinets under the window.
5. Hold the cabinets together using clamps. Ensure that they are flush on the top and front.
6. Predrill
holes in the side frames of each cabinet. Screw the cabinets together through the face frames with 2 1/2" wood screws.
7. Drill pilot
holes into the base pedestal and screw the cabinets to the frame.
8. If your cabinets are not a perfect fit, measure the distance between the wall and the cabinet sides. Measure the length from
the top of the cabinet to the floor.
9. Transfer the measurements to the filler material and cut.
10. Fasten the filler pieces to the sides of the cabinet and the frame with wood screws. Keep the filler piece flush with the front of
the cabinet.
11. Cut a piece of moulding the same length as the base to place at the front of the cabinet along the floor. Attach the moulding
using finish nails.
12. Measure the width and depth of the area. Cut a piece of 3/4" faced plywood to fit for the top. The top can overhang the
cabinets a little to accommodate a cushion.
13. Sand and finish the plywood to match the cabinets.
14. Run a bead of adhesive caulk along the top edges of the cabinets and filler pieces.
15. Place the top on the cabinets and press into place.
16. Fill all nail holes with caulk or wood putty. Touchup any areas to present a finished piece.
