I let this Kitchen SinkShroom drain stopper hold water in both sides of the sink for 30 minutes—and it didn’t budge. No leaks, no slow drain, no slipping. Just a perfect seal. If you’re tired of stoppers that never actually stop water, this one’s a win. Linked it on my LTK so you can grab the exact one I used.
