How to Repair a Chipped Sink

How to Repair a Chipped Sink

In addition to normal wear and tear, all it takes is dropping a heavy jar or glass bottle to cause unattractive chips and cracks in your sink’s surface. Fortunately, it is easy to repair a chipped sink yourself. Chipped sinks that are left untreated can eventually rust, leading to a more than just a cosmetic damage. Luckily, with a little do-it-yourself expertise, you can fix surface damage without the high cost of replacing the sink or hiring a professional to repair it.

The process used for repairing sinks, can also be used for fixing chips in enamel, porcelain and vitreous china toilets and bathtubs. Bigger chips might be more difficult to repair and repairing these yourself can run a greater risk of enhancing imperfections, such as a sloppy fill or off-color paint. If the chip or crack is considerable in size, you may want to replace the sink or hire a professional. More often than not, a sink will need to be replaced at some point because it is old, worn, or really outdated. Replacing a sink is one of the most popular kitchen or bath upgrades. Many times a sink and counter top are replaced as part of a larger remodel, but if you’re happy with your current design and only have a budget to replace the sink then you can simply upgrade it and you will save time and money. Here are a few tips on how to make chips and cracks practically disappear.


Enamel repair is a pretty simple task. Once your sink is cleaned and dried, remove any rust by sanding down the chipped area. Then, apply rubbing alcohol to the sanded area and let the sink dry completely. Once dry, apply an epoxy adhesive with something like a razor blade to fill the chip. Fill it in the same manner you would fill a hole in the wall, scraping it flush with the sink and wiping away any excess epoxy. While the epoxy is drying, fix any rough edges with a cotton swab dipped in nail polish remover. Allow the epoxy to dry for about 24 hours before you use the sink, and don’t scrub the repaired area for at least a week.


While porcelain sinks have beautiful finishes, they are quite fragile and susceptible to damage. Repairing a porcelain sink is the same as that of enamel, but in many cases you can simply just get a porcelain sink repair kit from your local hardware store or online. The kit is ideal for permanent repairs and is usually available in different colors to match your sink. If you’re matching an unusual color, you may have to combine colors for a more precise match.  You can also check with the sink’s manufacturer to see if they offer touch up paint.


Vitreous china sinks have a high-gloss, stain-resistant surface, and are the least likely to chip. Although this material is durable, abrasive cleaners can cause scratching and pitting. Two or three coats of epoxy applied on surface can restore smoothness. Even out the epoxy adhesive in the same way you would on enamel or porcelain sinks.


The mess of water lines, pipes and levers below your sink, that you typically ignore, will come into play when replacing your sink. If you would rather not tinker with the plumbing, then definitely hire a professional plumber to disconnect, remove and install the new sink.

A plumber will not choose a sink for you, though. If you need design help, you can consult a professional kitchen and bath designer but it may be hard finding one who will work on selecting a sink alone. A kitchen designer may charge several hundred dollars for their services. Obviously, it would be more cost effective for you to check out websites like Pinterest and Houzz for designs you like.

When hiring a plumber ask your friends and family for references; then make sure to check with your local government agency to make sure the plumber are licensed.

You should have the new sink ready for the hired professional upon arrival. Make sure your new sink is working properly and your bathroom is as clean as when they arrived before allowing the plumber to leave. It is actually their job to clean up the mess they made.

Labor costs vary across the country and travel time can also be included in an hourly rate when hiring a professional. Replacing a sink can be a 1 to 2 hour job for a pro and rates can be $75 to $150 an hour or more. All told, hiring professionals to choose and install your sink can cost up to $500 and add that to that the price of the sink itself


As mentioned above, replacing a sink is not the most time consuming task, but plumbing may be intimidating for many do-it-yourself-ers. With the proper tools and instructions, you can replace a sink successfully without any professional training at all. Just about anyone can do it. You will not only save money, but you will also gain a sense of satisfaction for learning how to work with plumbing. That can help with other plumbing projects around the house and save you money in the long run.

It is best to select a sink that is similar to the current one. But if you are considering a drastic style change, then you may be facing additional work in modifying the plumbing, counter tops and walls. There are many varieties of sinks and plumbing setups and it can take a bit of time, with changing the faucet, but the overall job is manageable for most DIYers. There are many videos on Youtube on how to replace a sink with walk-through instructions.


Bathroom and kitchen sinks get a lot of daily use and therefore tend to wear more quickly than other furnishings around your home. Fortunately it is a fairly easy and inexpensive job to repair chips so that they are almost invisible.
