Once you have removed your old kitchen, prepare your room by making sure your walls and floor are even, and that your walls are suitable for supporting your new kitchen. Now is also the time to prime and paint your walls, put in tiles or change your flooring. Marking cabinet positions and draw a layout of your new kitchen directly on the wall. Check that everything fits with the measurements from your plan and your electricity, water, gas and ventilation connections are where you want them. Also mark where to attach your new kitchen’s suspension rails. With the new IKEA's kitchen system for example, your cabinets can be hung directly onto a suspension rail making them easier to install and easier to adjust. It’s important to make sure your suspension rail is straight and level, and to secure it with the right screw type for your wall. Marking the right height for your suspension rail your base suspension rail needs to be hung 32 3/16″ above your floor’s highest point (measure to the underside of the rail). You should allow 22 5/16″ between the bottom of your wall cabinets and the bottom of your base rail when measuring for your upper rail.
