Why Is There Water Under The Bathroom Sink But No Leak? (Fixed)

When there is water around a sink, it’s normal to assume there must be a visible leak that’s the root cause.

In some cases, this is not going to be what’s happening.

Instead, you are going to have water under the bathroom sink but no leak.

If there is water under the bathroom sink but no leak, this means the silicone seal around the edges has worn down. To fix this issue, you will have to reseal the sink. This includes applying a silicone sealant along the edges.

Once the sealant is in place and allowed to settle, this will fix the issue for good. It’s best to reseal the entire bathroom sink rather than trying to pick specific spots.

This guide will explain how to stop water under the bathroom sink when there’s no leak.

How To Fix Water Under The Bathroom Sink Without Leaking

1. Find Where The Water Is

When there is water under a bathroom sink, you have to pinpoint where it is.

It’s one thing to know the water is there but you also have to find how it is flowing to that specific spot.

Is there a part of the sink’s seal that is damaged or worn down? Can you spot where the water is coming from?

It’s these details that can go a long way when you are trying to figure out the root cause of the issue. This is especially true when you know there is no leak to deal with.

Once you know where the water is coming from under the bathroom sink, you will have a much easier time applying the sealant later on.

2. Check the Seal

Your goal now is going to be to check the seal.

This includes running your handle along the edges of the bathroom sink. Try to find the moist spot and the root cause of this problem.

You will notice other parts of the seal are dry but that specific spot is moist. In some cases, it might also have water flowing out of it.

This is not a leak but it is just moisture that is getting through leading to water under the bathroom sink. Once you fix it, the issue will be gone.

3. Reseal The Sink With Silicone Sealant

This is now the best time to reseal your bathroom sink along the edges.

To do this, you are going to need a silicone gun. This is going to hold the silicone sealant that you use.

Once the silicone sealant is in your hand, you are going to begin applying it along the edges carefully. This will come out smoothly and ensure the area that was weak begins to fix itself.

It should not take a lot to complete the task.

Just make sure you are not getting the silicone sealant everywhere and apply it in all of the spots that need it.

4. Inspect The Seal

The last step is to inspect the seal once it has settled.

You should always go back to see whether or not the water is still coming under the bathroom sink.

For the most part, the problem should be gone if you have applied the silicone sealant thoroughly.

How Can You Tell Where A Water Leak Is Coming From?

You can tell where a water leak is coming from by finding moist spots. This is a common sign that area is dripping water and has to be fixed. To fix the issue, reseal that spot and the moisture will be gone.

It is common for people to not notice until the water is present.

This is why it’s best to immediately run your hand to determine the main spot where the water is flowing from.

Final Thoughts

These are the things to consider when there’s water under the bathroom sink but no leak.

If there’s water under the bathroom sink but no leak, this means the seal has weakened. To fix the seal, take a silicone sealant and apply it along the edges. This will take care of the damaged seal and make sure it’s robust again.

You will have to do this meticulously with the help of a silicone gun.

It will ensure you apply it the right way and the sealant does not spill everywhere. Take your time during the process, complete the entire bathroom sink, and don’t miss spots along the way.

If you do this, the water underneath the bathroom sink is going to be long gone. This is why resealing the sink is a must.
