The most practical choice is ceramic tiles as they are easy to clean and maintain. They can match almost all styles and decors.

You can install hard wood floors which are my personal favorite as it can create a rustic as well as an elegant atmosphere. However they are expensive and can be replaced by Laminate flooring which is economical and durable along with being stylish.

I would suggest Vinyl as it is one of the best options for kitchen flooring. It can be installed both in sheets and tiles, and is available in a variety of colors and patterns. Vinyl flooring is also available in a specially treated, stain-resistant form, which is designed to repel everyday spills.
