Polished chrome is classic, low maintenance and less expensive than nickel. If fingerprints, watermarks or bath products such as toothpaste get on chrome, they are easily removable with soap and water without leaving stains. On the other hand, nickel requires more rigorous upkeep. For example, here are the Care & Maintenance instructions from Newport Brass (they make Restoration Hardware fixtures) "General instructions for cleaning and caring for your faucets and bathroom fittings. Our faucets and bath fittings are made of solid brass and are of the finest quality. To maintain the finish on these items, please do not use any abrasive cleaners, rubbing alcohol, ammonia, detergents, brass or silver polish which will scratch the surface. Clean with a soft damp cloth. Applying a coating of a non-abrasive liquid wax to the clean surface of the product will protect the finish. Brass ProTech, product of Brasstech, Inc., can be used on all types of decorative painted and plated finishes. Simply apply Brass ProTech with a soft cloth and let it dry. Remove by rubbing gently with a soft dry cloth. Brass ProTech does not contain harsh abrasives. We highly recommend using Brass ProTech regularly on items finished in Polished Nickel (15), Satin Nickel (15S), Polished Silver (25) and Satin Silver (25S). Do not allow soap scum or minerals in water to build up on the surface finish of your faucets or bath fittings (including toothpaste). These will gradually wear away the protective coating or finish and diminish the beauty of your products. Living Finishes and Uncoated Finishes 03W, 08W, 25 and 25S are living finishes. 03N is an uncoated finish. Depending on maintenance and use, these finishes will naturally weather and change color. Our warranty does not cover living or uncoated finishes. Finish colors can vary and change in color is unpredictable." I recommend chrome in one of the many classic styles available to complement your carrara bathroom.

I would suggest you take out the cabinet that is to the right of the stove and use it elsewhere in the house -- perhaps in the bathroom or dining room with a hutch above it. Then, I would suggest you have someone install a lazy susan cabinet in the corner between the sink counter and the stove, meaning you would move the stove down a bit and have a small cabinet/counter top to the right of the stove. I would suggest you have the cabinets refinished in white and then paint the walls a pastel you like. If you would prefer white walls, then add white-painted crown molding and paint the ceiling a light neutral blue, such as Sherwin Williams Niagara Falls Blue. Then, I would suggest you choose a favorite accent color and use this sparingly in accessories like towels, pot holders, small vases or floral arrangements, and a valence above the triple windows. For a genuine 1940s look, you might have white ceramic square tiles with a rectangular red border installed as a back splash behind and above the stove. If you are replacing counter tops, I would suggest a light color such as white with a beige or light grey vein or striation for some sort of pattern. You might be able to find the same color and design in floor tile OR opt for a wood floor as another poster suggested.

And the seating areas are different, don't try to make it look like one area. I would put minimal ( if any) teal around the black sofa. Do your dining room. Then give you living room the same respect, it is it's own space

Having been brought up in a Lockwood home I can appreciate your love of the wood. I notice you have a light green bench and that would blend nicely with some similar colours in the room. I would consider having your cupboard doors replaced or sprayed to compliment the bench or visa versa you can have your bench updated with a new finish to modernise it. Perhaps you could just price out the cost of a new bench and leave the rest of the kitchen as it is. The odd bit around the dishwasher looks weird and that might be able to be fixed by curving a new bench into a small breakfast bar type set up. If there is room I would also reposition the microwave to the right of the cook top and use the existing space for a display or a lovely pot plant.
