The size and shape of the cabinets depend on the size of the kitchen. Measure your kitchen from wall to wall using a measuring tape, calculate its area after subtracting the space covered by the wall closets or other previously installed cabinets.
Use a computer software such as 'design my home' to draw many different configurations for your kitchen design. The bar should be the focus of attention in all these designs. The standard cabinet configurations that are in use these days include placing them along a wall, putting them in the centre of the room, or placing them in an L shaped fashion.
Choose the design best suited for your kitchen and give it finishing touches. If you purchased second hand cabinets, they will require a bit of refurnishing before putting them in your kitchen. If they slightly worn off, a coat of wood polish will suffice. However, if they are quite worn off you will have to use the wooden paste to fill in the cracks, and then use the polish to give the cabinets a finished shiny surface.
Put the cabinets to the desired height by fixing them on boards which are attached to the wall with the help of screws. The floor under the cabinets should be covered with tiles, or small sections of wood. Get an electrician to install an electrical outlet on top of the top cabinet. If you are good with electric things, you may not require the services of the electrician.
Make a counter at the top of the cabinet. There should be ample space for placing many glasses, which should be hung top down from the top cabinet to give your bar a professional look. You can install granite stone on top of the cabinet to give your bar a warm look.
