Most Fitbits are water-resistant, not waterproof — and the difference matters
Fitbit uses the term water-resistant for nearly all its current trackers, which means they can handle splashes, sweat, and brief immersion in fresh water. They are not waterproof, which would mean they could survive indefinite submersion or saltwater exposure. A water-resistant Fitbit can survive a shower or a light rain, but not a swimming pool or ocean.
The depth rating — usually listed as 50 meters or 100 meters — tells you how deep the device can go before water pressure damages it. A 50-meter rating means the tracker can handle splashes and brief dunks. A 100-meter rating means it can handle swimming in a pool. Neither rating covers saltwater, hot tubs, or diving.
If you plan to wear your Fitbit while swimming, you need a model with a 100-meter water-resistance rating. If you only shower with it on, a 50-meter rating is enough. If you want something that survives saltwater or diving, no current Fitbit meets that standard.
Key Takeaways
- Fitbit Sense 2, Versa 4, Inspire 3, and Charge 6 all carry a 50-meter water-resistance rating, suitable for showers and splashes but not swimming.
- Fitbit Ace LTE and some older Fitbit models have a 100-meter rating, which means they can be worn while swimming in a pool.
- Water-resistant does not mean waterproof — no Fitbit survives saltwater, hot tubs, or pressurized water like a shower jet aimed directly at it.
- The water-resistance rating can degrade over time if the seals wear out, so avoid intentional submersion if your Fitbit is more than two years old.
Fitbit models with 50-meter water resistance
The Fitbit Sense 2, Versa 4, Inspire 3, and Charge 6 all have a 50-meter water-resistance rating. This means they can survive a shower, rain, and accidental splashes. You can wash your hands while wearing one. You cannot intentionally submerge them in a pool or take them snorkeling.
The 50-meter rating comes from the IP67 dust and water rating, which is the same standard used for many smartphones. It means the device can handle immersion in up to 1 meter of fresh water for up to 30 minutes. In practice, Fitbit recommends you do not intentionally submerge these models at all — the rating is a safety margin, not a feature to rely on.
If you shower daily with your Fitbit on, a 50-meter model will hold up. If you want to track swimming sessions, you need a different model.
Fitbit models with 100-meter water resistance
The Fitbit Ace LTE has a 100-meter water-resistance rating, which means it can be worn while swimming in a pool. The 100-meter rating comes from the 5 ATM (atmospheres) standard, which is designed for swimming and snorkeling in fresh water. Fitbit does not currently make many models at this level, so your options are limited.
If you own an older Fitbit — such as an Ionic or some Charge models from 2018 or earlier — check the original product page or manual to find its rating. Some older models had 100-meter ratings that newer versions dropped.
What water-resistant does not cover
Water-resistant Fitbits are not safe in saltwater, chlorinated pools, hot tubs, saunas, or under a pressurized shower jet. Saltwater corrodes the seals faster than fresh water. Chlorine and hot water can degrade the materials. A shower jet aimed directly at the device can force water past the seals even if the device is rated for immersion.
If you swim in the ocean, wear your Fitbit on your wrist but rinse it with fresh water when ready after. Do not submerge it. If you use a hot tub, remove the Fitbit first. If you have a high-pressure showerhead, avoid pointing it directly at the device.
How water resistance degrades over time
The seals that make a Fitbit water-resistant are rubber or silicone gaskets. Over two to three years of daily wear, these seals can crack, shrink, or lose their grip. A Fitbit that was water-resistant when new may not be by year three, even if you have never submerged it.
If your Fitbit is more than two years old and you have worn it daily, treat it as less water-resistant than the rating suggests. Avoid intentional submersion. If you drop it in water, dry it quickly and do not use it until it is completely dry inside.
Fitbit does not sell replacement seals or offer a way to re-seal the device yourself. If the seals fail and water gets inside, the device usually stops working.
How to care for your water-resistant Fitbit
Rinse your Fitbit with fresh water after exposure to sweat, chlorine, or saltwater. Use a soft, dry cloth to wipe it down. Do not use soap, alcohol, or abrasive cleaners on the band or case. Do not submerge it intentionally, even if the rating suggests you can.
If water gets inside the device — you see condensation under the screen or the device stops responding — remove the band, place the Fitbit in a warm, dry place, and leave it there for 24 hours. Do not charge it or try to use it until it is completely dry. If it does not recover, the seals have likely failed.
Store your Fitbit in a dry place when you are not wearing it. If you live in a humid climate, consider storing it in a small container with a silica gel packet to absorb moisture.

Frequently Asked Questions
Can I wear my Fitbit in the shower?
Yes, if it has a 50-meter or higher water-resistance rating. Fitbit Sense 2, Versa 4, Inspire 3, and Charge 6 are all safe in the shower. Avoid pointing a high-pressure showerhead directly at the device, and rinse it with fresh water afterward if you use soap.
What happens if I accidentally drop my Fitbit in water?
If it is a 50-meter or higher model and the water is fresh, remove it when ready and dry it with a soft cloth. Let it air-dry completely for a few hours before wearing it again. If water got inside and you see condensation under the screen, place it in a warm, dry location for 24 hours before using it.
Can I swim with my Fitbit?
Only if you have a model with a 100-meter water-resistance rating, such as the Fitbit Ace LTE. Models with 50-meter ratings are not designed for pool swimming. Even with a 100-meter rating, avoid saltwater and chlorinated pools — rinse with fresh water when ready after.
Is my old Fitbit still water-resistant?
Probably less so than when it was new. The rubber seals degrade over two to three years of daily wear. If your Fitbit is older than three years, treat it as less water-resistant and avoid intentional submersion, even if the original rating was high.
What should I do if water gets inside my Fitbit?
Stop using it when ready. Remove the band and place the device in a warm, dry location for 24 hours. Do not charge it or try to turn it on. If condensation clears and the device works again, the seals held. If it does not recover, the seals have failed and the device may need replacement.
