How‌ ‌to‌ ‌Check‌ ‌for‌ ‌a‌ ‌Bathroom‌ ‌Water‌ ‌Leak‌

When plumbing is pushed past a certain point, especially in older homes, you run into common and often easy-to-fix issues such as leaks. A bathroom water leak is especially troublesome. For homeowners, it means money wasted on their utility bills. From an environmental standpoint, it’s wasted water. 

Bathroom leaks happen all the time. It’s an early sign that there’s a plumbing leak when your water bills skyrocket. If you can break down your monthly usage and see you’ve used more water recently than before, it could relate to a bathroom water leak. Get the leak fixed as quickly as possible. Ideally, you should contact a plumber like Gold Medal Plumbing and Drain, but you can also try to repair the leak yourself.

Here is a detailed guide on how to check for a bathroom water leak:

1. Smells


You don’t always get a smell with a bathroom water leak. If it has been happening for a little while, you might be able to smell the dampness, mould, and mildew. The smell is that of an old basement. It can be very musty. You may have difficulty finding the source of the scent, but it’s something you can try to help check for a bathroom water leak.

2. Puddles

When you haven’t taken a bath in a long time, puddles of water on the floor may mean you have a leak. Soak up the puddle with towels. Once it’s dry, do a close inspection of where the water’s coming from. An easy way to do this is to lay out a few dry towels and wait. Check back in a few minutes and see what’s wet.

3. Dampness

A bathroom water leak can occur anywhere there are pipes, including the ceiling. Look for dampness anywhere on the ceiling or floor. If you find any, it could be a sign there’s a non-visible leak in your bathroom. In that case, getting it addressed quickly is essential as it could lead to permanent structural damage.

4. Faucets

A lot of bathroom faucets drip. It’s not a sign of a leak. What is, however, is when a faucet seems wobbly. If it’s moving around and isn’t affixing properly, it’s a sign there’s a leak from the rim. Water is coming up under the faucet base, and there you have your leak. When it comes to bathroom leaks, this one is among the easier to fix. You have to retighten the base of the faucet beneath the sink.

5. Mould Growth

Mould is not out of the ordinary in a bathroom. It’s wet, humid, and a perfect spot for mould to grow. If you notice more than usual or mould growing in spots that aren’t wet, it may originate from a leak in the wall or dampness in and around it. Pay close attention to where patches of mould are growing, especially if this is a new occurrence.

6. Inspect Connections

If you know a little about plumbing, you can inspect a few areas like the water heater, pumps, hoses, and valves. If there’s oxidation or discoloration, there’s a good chance your plumbing’s experiencing a prolonged leak. Though you may restrict your leak search to the bathroom, a single leak can lead to failings elsewhere in the plumbing. It’s all connected. A professional plumber can help do a more thorough inspection if you feel it’s more worth it.

7. Condition of Your Tiles

Bathroom tile crack

Bathroom tiles, in some cases, crack, loosen, or the caulking between them damages. This will create openings for moisture to get through and into the materials behind them. This can be expensive to fix and can create massive amounts of damage before you can even see what’s happening. So, check your tiles. If there are cracks or damage, you will want to get it repaired without delay.

8. Water Noises in The Wall

You may hear a leak before it’s ever seen. The sound of dripping water or a hissing pipe is a preview that something is wrong. The best thing is to have it inspected if there are noises you aren’t familiar with happening from your walls. An unfamiliar noise coming from a leak can significantly damage a property long before you see anything.

9. Food Colouring in the Toilet

If you suspect your toilet is the source of a bathroom water leak, place food colouring or a dye test tablet inside the tank at the back. Don’t flush. Wait for 10-15 minutes. If you notice there’s colouring seeping into the toilet bowl, you know you have a leak. Normally, it shouldn’t do this. Plumbers often use this dye test to diagnose leaks quickly and efficiently, and it’s something homeowners can try themselves as well.

10. Tub Cracking or Shower Cracks

Sometimes a tub or shower enclosure can crack, causing a leak. This can come from age, structural pressure, weight, or some other source. It can be fixed with some two-component epoxy or any bathtub repair kit.
