Most Fitbits are water-resistant, but not waterproof—and that distinction matters in the shower
You can wear most current Fitbit models in the shower because they have a water-resistance rating of 5 ATM (atmospheres). That means they can handle water pressure up to 50 meters deep, which covers splashing, brief submersion, and yes, shower spray. However, water-resistant is not the same as waterproof. Water-resistant devices are designed to resist water damage under normal conditions, but prolonged exposure to hot water, soap, and steam can eventually cause problems.
The key risk in the shower is not the water itself but the combination of heat, pressure, and chemicals. Hot water can degrade the seals around buttons and sensors over time. Soap residue can build up in crevices. Steam can seep into gaps that cold water alone would not penetrate. If you shower daily and wear your Fitbit every time, you are accelerating wear on those seals.
Some older Fitbit models—including the original Fitbit Charge and some early Fitbit Flex versions—have lower water-resistance ratings (1 ATM or 3 ATM) and should not go in the shower at all. Check your device's manual or the Fitbit website for your specific model's rating before you start wearing it in the bathroom.
Key Takeaways
- Most current Fitbit models are rated 5 ATM water-resistant and can handle shower water, but water-resistant does not mean waterproof.
- Hot water, soap, and steam pose more risk than cold water because they can degrade the seals around buttons and sensors.
- Older Fitbit models with 1 ATM or 3 ATM ratings should not be worn in the shower.
- Rinsing your Fitbit with fresh water and drying it after the shower extends the life of the seals and prevents soap buildup.
How to check your Fitbit's water-resistance rating
Your Fitbit's manual or the product page on Fitbit's website will list the ATM rating. Look for language like "water-resistant to 5 ATM" or "suitable for swimming." If you no longer have the manual, go to the Fitbit app, tap your profile icon, select your device, and scroll to the specifications section. The rating will be listed there.
If your device is rated 1 ATM or 3 ATM, it is splash-resistant only—meaning it can handle accidental water exposure like rain or a spilled drink, but not intentional submersion or shower spray. Keep these models away from the shower, bath, and pool.
What happens if water gets inside your Fitbit
If water seeps past the seals, you may notice condensation under the screen, erratic readings, or the device stopping to respond to taps. Sometimes the device will dry out on its own over a few days and work again. Other times, the water causes permanent damage to the battery or circuit board, and the device will not turn back on.
Fitbit does not cover water damage under the standard warranty, even on water-resistant models, because the company considers water damage a result of misuse rather than a manufacturing defect. If your device stops working after water exposure, you will likely need to replace it out of pocket.
Best practices for wearing your Fitbit in the shower
If your Fitbit is rated 5 ATM, you can wear it in the shower, but a few habits will keep it working longer. Rinse it with fresh water after you shower to remove soap, shampoo, and conditioner residue. Dry it with a soft cloth—do not use heat like a hair dryer, which can damage the battery. Avoid wearing it under very hot water (above 104°F or 40°C) for extended periods, as extreme heat stresses the seals.
Do not submerge your Fitbit intentionally, even if it is rated 5 ATM. That rating assumes brief, accidental exposure, not deliberate dunking. Also avoid chlorinated pools and salt water, which are harsher on seals than fresh water or shower spray.
When to take your Fitbit off before the shower
Even if your Fitbit is water-resistant, you may want to remove it before showering if you are using very hot water, if you shower multiple times a day, or if you have had previous water damage issues with electronics. Some people remove their Fitbit during showers straightforward to give the seals a break and extend the device's lifespan.
You should definitely remove your Fitbit if you are taking a bath, using a sauna, or soaking in a hot tub. These expose the device to prolonged heat and high water pressure, which can overwhelm the seals even on a 5 ATM device.

Frequently Asked Questions
Can I wear my Fitbit while swimming?
If your Fitbit is rated 5 ATM, you can wear it while swimming in a pool or ocean. However, chlorine and salt water are harder on the seals than fresh water, so rinse it thoroughly with fresh water afterward and dry it completely. Some users prefer to remove their Fitbit before swimming to avoid unnecessary stress on the seals.
What should I do if my Fitbit gets wet and stops working?
Turn it off when ready and do not try to charge it. Let it air-dry in a warm, dry place for at least 24 to 48 hours. Do not use heat like a hair dryer. After it has dried completely, try turning it on again. If it still does not work, contact Fitbit support, though water damage is typically not covered under warranty.
Will my Fitbit track my shower time?
Your Fitbit will continue to track steps and heart rate during your shower if you are moving around. However, water on the sensor can sometimes cause inaccurate readings, so do not be surprised if your stats look a bit off during or when ready after showering.
Is it okay to wear my Fitbit in a hot tub or sauna?
No. Hot tubs and saunas expose your Fitbit to prolonged heat and high humidity or steam, which can damage the seals even on a 5 ATM device. Remove your Fitbit before entering either one.
