Reasons to Replace Your Bathroom Sink

People replace bathroom sinks for many reasons, but the "why" behind this small bathroom reno task can actually impact the cost of installation.


Perhaps the kids smashed it one too many times with hard toys and there's a crack, or maybe time has worn away the protective glaze. Replacing the sink, in this case, can help reduce functionality issues or leaks.

Mold or Mildew

An ill-fitting sink or one that's damaged could support mold or mildew growth. Tiny leaks, seeps or problems draining, for example, can spur such problems on. You’ll likely have to fix this problem before you can install a new sink, which may add to the total cost.

It’s Upgrade Time

If you want a more functional faucet or bathroom vanity, you may wish to replace the bathroom sink. Or maybe you just think the existing sink is ugly. You're tired of looking at an eyesore every time you brush your teeth, or you've redecorated the rest of the bathroom, and it's time for the sink to catch up.

Average Cost to Replace a Bathroom Sink

According to HomeGuide, the average cost for replacing a sink runs from $280 to $1,200 (CAD 360 to CAD 1,550), including materials and labor.

The Home Depot, for example, charges $200 to $350 (CAD 260 to CAD 450) to install a sink, though that doesn't include the cost of the sink, faucet or any related plumbing work that might need to be done.

If a plumbing issue is the reason you want to replace the sink, you may want to consult a professional for assistance. They may need to make more changes than just the sink to resolve the issue. They can also let you know if sink repair is a good alternative to replacement.

How Long Does It Take to Change a Bathroom Sink?

If you're just swapping out a sink for another or dropping a vanity and sink into place, the job usually takes less than four or five hours. Bigger sink replacement jobs can take a bit longer. It all comes down to how skilled you are, whether you run into unplanned issues and what you need to modify to fit your needs. Need to cut out more space on a countertop?
