I feel like in this case function should trump form. Islands without sinks may be gorgeous (form), but if it makes your kitchen less functional, it's still a bad decision. Kitchen sinks in islands really aren't the end of the world.

OP here, because I just love love love islands with nothing on them. But wondering if I will hate the lack of balance later.

There was a thread here long ago on how much people actually love having nothing on their islands vs. with a sink.

If you only have one wall, why are you so opposed to having the sink in the island? From a balance perspective, that is much more functional (and completes the sink/fridge/stove triangle instead of having them in a line)

Still in search of kitchen layout/inspiration pics w no sink on the island, and only one other wall where stove and sink need to go.
Does the stove/range still stay in the center across the island?
Should we add a window to each side, and have the sink under one of these windows? Will the other window now make the kitchen look unbalanced?
