I recall a Pasadena project where a lovely marble vanity masked a slow-clogged drain, and the odor lingered despite daily cleaning. Typically, old toothpaste, hair, and soap residue build up, creating breeding grounds for bacteria that release foul smells. Another source is a dry P-trap—the curved pipe under your sink—which can lose its water barrier if you rarely use the sink or if there’s a leak.Quick DIY Fixes: My Go-to SolutionsFirst, I tell clients to flush hot water down the drain for several minutes, often paired with a cup of baking soda and vinegar. The fizzy reaction breaks down slimy buildup. For a deep clean, removing the drain stopper lets you scrub away hidden residue. If these steps don’t solve it, I inspect the P-trap for moisture. A simple refill—pouring a glass of water into the pipe—restores its seal and often banishes odor immediately.Professional Touches for Stubborn OdorsSometimes, the smell persists because of venting problems or older pipes that need more than surface cleaning.
