You can conceal plugs and outlets either by planning them into cabinets when designing your kitchen reno, or by using outlet cover extension cords to reroute existing outlets somewhere a little more out of sight, such as into a pantry, appliance garage, or just further along your counter where you can disguise the extension behind lager appliances or decorations.
Alternatively, you can layer decor in front of the plug, such as stacking cookbooks or decorative cutting boards to add a little extra flair to your space all without having to rework electricals.
