I laughed (kindly!) and said, "Well… anything’s possible, but maybe not everything’s sensible." That project taught me that small spaces aren’t limitations – they’re design playgrounds. So today, I’m sharing 10 sink ideas for tiny bathrooms that I’ve tested, tweaked, and fallen in love with.Wall-mounted SinksOne of my go-to tricks—mounting the sink directly to the wall—frees up floor space and makes the whole room feel lighter. It’s also a budget-friendly upgrade, though you’ll need sturdy walls for secure installation. I’ve used it in several small-space bathroom designs with great results.save pinCorner SinksPerfect for those awkward layouts where every centimeter counts. A corner sink can turn a dead zone into a functional spot, though you may be limited in basin shape options. I once fit one into a studio where the door practically hit the toilet—it was a lifesaver.save pinIntegrated Countertop SinksCombining the countertop and sink into a single piece creates a sleek look and fewer seams to clean. Great if you love minimalism, but be ready to commit to the counter material since replacing just the sink isn't easy.save pinPedestal SinksStill a classic in my book—elegant, charming, and airy. The trade-off is losing storage, but in a powder room, that might be perfectly fine.save pinVessel SinksThese sit on top of the counter and can become the statement piece in a small bathroom. Just remember they take up counter space, so plan storage elsewhere—perhaps with wall shelves or a custom vanity layout.save pinUndermount SinksSeamless and easy to clean, undermount sinks work best with stone or solid surface counters. I love them for keeping things tidy, but they require precise cutouts during fabrication.save pinTrough SinksSkinny yet long, trough sinks allow two people to use the space side-by-side without needing double vanities. I've fitted them in narrow bathrooms for couples who get ready at the same time.save pinConsole SinksThese have slender legs and an open feel, sometimes with a towel rack built in. They work beautifully if you want storage baskets underneath without a heavy cabinet footprint.save pinFloating Vanity with SinkMy favorite trick for creating the illusion of space—mounting a vanity off the floor lets the floor breathe visually, plus you can tuck a tiny stool or basket under it. This works brilliantly with precise AI-assisted spatial planning.save pinMini Sink for Powder RoomsWhen all you need is a wash-up station, go for a scaled-down basin. They’re adorable, functional, and perfect for ultra-compact WCs—just watch the splash radius!save pinFAQQ: What’s the smallest sink size for a functional bathroom?A: Around 12–16 inches wide works, but comfort depends on placement and faucet design.Q: Can small bathrooms fit stylish sinks?A: Absolutely.
