You will need 9 simple items to hide your trash can if you have a necessity ( mine is named Phoenix) or you just don't like to look at your trash.
1- small plactic trash can that will fit inside of your chosen cabinet with room to spare ( the office type work well)
3- wood screws 1- 1 1/2 in long ( you will want to measure the thickness of your cabinet door, keep it shorter)
3- metal washers 1 1/12 in diameter with center hole small enough that your chosen screw will not fall through
1- screwdriver ( type to match chosen screw) i used a racheting one for easier installation will have to fit in trash can
1- ice pick, awl or other sharp tool to punch hole through plactic of trash can
Once you have decided where to place the screws, use the ice pick to bore 3 holes into the trash can for the screws. Place a screw through each washer and then screw each one through the plastic.
At this point, you can go ahead and screw each screw into the wood of the cabinet door ( I started with the center screw) It is a little tough to get the screws going this way, so you can take the option to partially pre drill the screw holes, just be careful that you have them lined up so that the door will still close.
tighten all three screws down so that the can is firmly secured on the inside of the cabinet door.
Please note that the general shape of your trash can and whether or not it has any kind of a lip on top, will determine if you will be torquing the screws all the way in , or just enough to support the can in place.
