But the cheapest cabinet hack of them all is buying ready-to-assemble or used cabinets. RTA cabinets are pre-cut and packaged to be ready for assembly.
You can find them in big box stores like The RTA Store, Home Depot, and Costco. If you're going this route, check that you're getting a quality product.
Low-quality RTA cabinets will have thin drawers or frames, which means they won't last long. Their finishes will also be sprayed instead of brushed on.
For used or reclaimed cabinets, check second-hand stores like Habitat ReStore and online marketplaces like Craigslist, eBay, Etsy, Buy Nothing, and Facebook Marketplace.
Finally, consider alternative materials or finishes to reduce costs. Instead of solid wood, opt for plywood or laminate which is durable and easy to maintain.
