One form of rustic leans toward all things natural. To get started with rustic in your kitchen, you want to make sure your cabinets are in line with the style you want. If new cabinets are part of the plan, you can save a large chunk of change by finding some natural wood discount kitchen cabinets.
Discount kitchen cabinets aren't meant to be cheap. Essentially, RTA kitchen cabinets fit into the category of discount kitchen cabinets; and they are usually made quite well. RTA kitchen cabinets come ready to assemble. This is what saves you money. Because you are doing the assembly and installation, RTA kitchen cabinets can be a great way to start your rustic kitchen.
To bring the natural rustic design into your kitchen, you want cabinets, counters and floors to be made of natural looking materials as much as possible. Perhaps you live in a home that already features granite countertops. If this is the case, you can build off of that natural material by placing hues into the room that coordinate with the shade of granite on your counters.
In a nature inspired rustic kitchen, floors can be stone or wood. Stone tends to do very well in the kitchen because it can hold up to getting wet better than wood. On the counters, you want to eliminate as much clutter as possible. The naturally rustic kitchen will have a minimalist feel, because the main point of this type of decor is to bring natural substances in.
Another way you can feel rustic in your kitchen is through a country style rustic. The country rustic kitchen exudes warmth that calls you to come in and stay awhile. Think light and bright. Think white kitchen cabinets and wood floors. While stone can also fit into a country rustic kitchen, you want to think of a farmhouse when considering what to add; and most farmhouses won't feature slate tile floors.
If you have enough in your budget, you could consider changing countertops to the big butcher block style wood counters. If this is not possible but you have some room in your kitchen, you could build a small cart with butcher block top to place as a center island.
On the counters of the country rustic kitchen, you can place wicker baskets with fruit or faux eggs. The table in a country kitchen could be wood, wicker or white wrought iron.
A rustic kitchen should never be cluttered. The feel should be warm and inviting regardless of the style of rustic you choose. Resist the urge to go overboard with themed decorator items. Trends come and go and when you overload, you may have less tolerance for the decor than if you keep it simple.
