Can Mice Come Up Through Bathtub Drains?
Can mice come up through bathtub drains? The short answer is: it is possible, but not common.
While mice are incredible climbers and can squeeze through incredibly small spaces (as small as a dime), bathtub drains are not the most accessible entry point.
That said, if your plumbing has cracks, loose fittings, or leads to open or exposed pipes in crawl spaces or basements, then the risk increases significantly.
More often, mice enter bathrooms through gaps around pipes, vents, or openings near the tub, not directly through the drain. But if there is a breach in your plumbing system, they can potentially navigate it to make their way upward.

How Mice Navigate Plumbing Systems
Mice are motivated by food, shelter, and warmth, and plumbing systems offer hidden passageways that run throughout a home. Here is how mice use them to their advantage:
- Drainage Pipes: If dry or cracked, these pipes can provide a route for rodents.
- Vent Pipes: Vertical pipes can be used like ladders by nimble mice.
- Wall Gaps: Plumbing often runs through wall voids, which mice can exploit to move between rooms.
- Access from Crawl Spaces: Many bathtubs sit above a crawl space or open area, which mice can enter if the foundation is not sealed properly.
Bathtub drains typically have water traps (P-traps) that hold water and prevent odors and pests from coming up.
However, if your drain is rarely used or dry, that protective barrier might be missing, giving mice a clearer path.
Signs a Mouse May Be in Your Bathroom
If you are concerned that a mouse has found its way in, keep an eye (and ear) out for the following clues:
- Droppings: Small, dark pellets found around the tub or near plumbing fixtures.
- Scratching noises: Sounds coming from inside walls, especially at night.
- Gnaw marks: On baseboards, pipes, or even plastic fixtures.
- Unusual pet behavior: Pets staring or pawing near the bathtub or drain.
- Foul odors: A musty or ammonia-like smell can indicate urine or nesting materials.

How to Prevent Mice from Coming Through Drains
Here are effective strategies to mouse-proof your bathroom and drains:
1. Keep Drains Moist:
Ensure your bathtub and sink drains retain water in the P-trap to block access. Run water weekly in unused drains to keep traps filled.
2. Install Drain Screens:
Use metal mesh screens or covers that allow water to flow but block pests. These are especially useful in basement tubs or showers.
3. Seal Gaps Around Pipes:
Use steel wool and caulk or expanding foam to seal holes where pipes enter the wall or floor. Mice cannot chew through metal materials.
4. Inspect Crawl Spaces:
Look for access points below the tub. Close off any openings and set traps if needed to catch any rodents hiding in those spaces.
5. Keep the Bathroom Clean:
Do not leave towels or clothing on the floor. Keep toiletries and food items (if any) sealed and off the ground to avoid attracting pests.
6. Work with a Pest Control Professional:
If the infestation persists or you suspect mice are inside your plumbing system, a professional can locate the breach and treat the problem effectively.
Can Mice Come Up Through Bathtub Drains? (FAQs)
Can Mice Swim Up through Pipes?
Mice are surprisingly good swimmers and can survive in water for extended periods. However, it is very rare for them to swim up through water-filled pipes like those found in modern plumbing.
What Attracts Mice to the Bathroom?
Bathrooms provide warmth, moisture, and hiding spots. Even a dripping pipe can offer a small but enticing water source. If nearby rooms contain food, mice may pass through the bathroom as a route.
How Do I Know if a Mouse Came through the Drain?
Look for droppings near the tub, hair or debris in the drain that was not there before, or visible damage to drain components. A plumber or pest pro can confirm this by inspecting the pipes.
Are Chemical Drain Cleaners Effective Against Mice?
No. Drain cleaners might deter mice temporarily with strong odors, but they will not eliminate or prevent an infestation. Use physical barriers and sealants instead.
