If you are renovating your kitchen but need to spend less money, consider using laminate flooring and countertops. These synthetic options are generally much less expensive than wood, tile, or stone. They are also easier to care for. Many of these products are designed to closely mimic the natural products, so that the difference is only visible on close inspection.
If you do not like the looks of your hardwood, tile, or even laminate flooring, you may want to install carpeting. It gives a home a comfortable, lived in feeling and is much better for your joints. Just remember to pull it up if you ever move, since no one wants a home with used carpeting.
