In general, the cheapest type of cabinet door is Flat. The 5 most common types of cabinets are Flat, Shaker, Glass, Cathedral, and Beadboard.

1. Beadboard (also known as tongue-and-groove) cabinet doors are most popular in a rustic cabin or cottage design.
2. The Cathedral cabinet design has an indented cut archway along the top of a square border. These cabinets are less popular in contemporary kitchen designs now and are harder to give a fresh face to than the Flat or Shaker styles.
3. Glass cabinets can be quite stunning, adding the feel and look of space to an otherwise closed-off kitchen. Glass can be pricey, depending on the exact look and style you choose for your cabinets. The other potential drawbacks are the fragility of glass and its tendency to collect grease and dust in the air. This can lead to it looking smudged or dirty.
4. Shaker cabinets have been popular since they were first constructed in the late 19th century. Their design features an elegant simplicity that fits well with many different styles and design schemes.
5. The last type of cabinet, Flat, is usually the cheapest option. This is because their flat slab of wood or laminate requires the most negligible manufacturing costs. This style gives your space a minimalist feel and looks, allowing your hardware choices to shine. The other advantage of Flat cabinets is that they can be quite easy to refinish and clean.
