The average length of time for a kitchen remodel can vary widely depending on the size and scope of the project, as well as other factors such as the availability of materials and the availability of contractors. A full kitchen remodel can take anywhere from a few weeks to several months to complete.

As for the type of cabinets to use, there are many options to choose from. Some popular choices include:

Plywood cabinets: These are made from thin layers of wood veneer pressed together, which makes them strong and stable.
Particle Board cabinets: These are made from wood chips, shavings, and sawdust that are pressed and glued together. They are generally less expensive than plywood cabinets, but they may not be as durable.
MDF (medium-density fiberboard) cabinets: These are made from wood fibers that are mixed with resin and then pressed into sheets. They are strong and stable, but they are not as resistant to moisture as plywood or particle board.
Solid wood cabinets: These are made from solid pieces of wood, which makes them very durable and long-lasting. However, they can be more expensive than other types of cabinets.

Ultimately, the best type of cabinets for your kitchen will depend on your budget, your style preferences, and the amount of use your kitchen gets.
