how big can islands be?
The maximum island size, in my opinion would be one that is 6-feet deep and perhaps 10-feet long. This is a massive amount of flat space, or even multi-level space, for an island. One of the things to keep in mind is how the top of the island will be cleaned. Each part of the top must be reachable by hand so spills, food and dirt can be cleaned with ease. Some islands may not have to be attached to the floor. The weight of the cabinets, top and all of the things stored in the island cabinets may reach close to, or over, 1,000 pounds for a massive kitchen island.
