To replace the bottom of a sink cabinet with plywood when there is a piece of wood between the cabinet doors, you will need to follow these general steps:
Empty the cabinet: Remove all items stored in the cabinet to create a clear working space.
Remove the cabinet doors: Open the doors and locate the hinges. Unscrew the hinges from the cabinet frame and remove the doors. Set them aside in a safe place.
Remove the center piece of wood: If there is a piece of wood between the cabinet doors that obstructs access to the cabinet bottom, you'll need to remove it. Look for screws or nails attaching it to the cabinet frame and remove them. Carefully take out the piece of wood.
Measure and cut the plywood: Measure the dimensions of the bottom of the sink cabinet using a tape measure. Transfer those measurements onto the plywood sheet, ensuring it fits properly. Use a circular saw or a jigsaw to cut the plywood along the marked lines.
Place the plywood: Once the center piece of wood has been removed, you should have an open space to insert the plywood. Slide the plywood sheet into the cabinet, positioning it to fit snugly against the sides and back.
Secure the plywood: To hold the plywood in place, you can use screws or nails. Place them through the cabinet sides and back into the edges of the plywood. Be careful not to use long screws that might protrude through the cabinet exterior.
Reattach the center piece of wood (optional): If you wish to reattach the piece of wood that was initially obstructing access to the cabinet bottom, you can do so by using the same screws or nails you removed earlier. Make sure it fits securely and does not interfere with the newly installed plywood.
Reinstall the cabinet doors: Align the hinges on the cabinet frame with the hinge mounting plates on the doors. Secure the hinges by screwing them back into place. Test the doors to ensure they open and close smoothly.
Clean up and organize: Before finishing, clean up any debris or sawdust from the cabinet. Return the items you removed earlier back into the cabinet, organizing them as desired.
By following these steps, you should be able to replace the bottom of the sink cabinet with plywood even if there is a piece of wood between the cabinet doors.
