Sink Repair FAQs, answered by experts

For safety when installing a vanity, attaching the vanity to the wall is ideal to prevent it from moving. Typically, sinks must be 4 inches away from bathtubs. Also, most states require that you have 21 inches in front of a sink, but the National Kitchen and Bath Association (NKBA) recommends 30 inches for more comfort.

If you have the patience and help to install a kitchen sink, you can do it yourself. This DIY project works best when replacing a sink that fits the existing hole, and the fittings and plumbing are in good condition. If you're worried about the plumbing's condition or aren't sure how to shut the water and power off to the garbage disposal and dishwasher, it's best left to a sink installation pro.

Clean regularly with non-abrasive cleaners, avoid pouring grease down the drain, and check for leaks under the sink.

Replacing the countertop with another that fits the same size and cut out shouldn't take longer than four to five hours. The installation job entails removing the plumbing connections, unscrewing the old sink connectors, removing the countertop, placing and gluing the new countertop, and connecting the plumbing hookups.

Yes, you can replace just the top of a bathroom vanity, which you may choose to do if you love the look of your vintage bathroom cabinets, but the countertops are not your style. Fortunately, it is pretty simple to detach a vanity top from a base for replacement, but you should still shut off the water to avoid a leak. Replacing only the vanity top costs around $400 to $4,300.
