The cabinet came in two very heavy boxes. The instructions were average but the pictures helped through the assembly process.  Unfortunately, the pictures displayed the single cabinet and I purchased the double cabinet, so there were some differences. It was a two-man operation - do not attempt the build or setup by yourself! Total time was about 3 hours. All tools were provided, but I needed to increase the glass run to accommodate the side panels. Everything fitted well and there were a few extra washers; otherwise the build was pretty easy.
