We started by adding a tile backsplash behind the stove.
Next, we added black enamel drip pans to our stove (a 60-second installation, but amazing how a small change can make a big difference on a boat).
Then, we installed our new freezer (which took hours and had no effect on the appearance of the galley--pretty much the opposite of the drip pans).
After installing the freezer, we added a built-in garbage and a matching vent to keep the freezer area cool.
To keep the freezer area even cooler, we next installed a little exhaust fan by the vent.
