Can You Shower or Swim With a FreeStyle Libre?
Yes, you can shower and swim with a FreeStyle Libre 2 or FreeStyle Libre 3, within Abbott’s limit. Abbott says the “Sensor is water-resistant in up to 1 metre (3 feet) of water for a maximum of 30 minutes” (Abbott UK, FreeStyle Libre 3).
So is the Libre 3 waterproof? Not quite. It’s water resistant, which means showers and short swims are fine, but deeper or longer soaks are outside what Abbott allows.
Last checked: 20 October 2026, against Abbott’s UK FreeStyle Libre 2 and Libre 3 pages, its US FreeStyle Libre 2 and Libre 3 pages, and its US FreeStyle Libre 3 Plus water-resistance FAQ.
What Abbott says about water for the Libre 2 and Libre 3
Abbott’s UK product pages for the FreeStyle Libre 2 and FreeStyle Libre 3 carry the same footnote, word for word:
“Sensor is water-resistant in up to 1 metre (3 feet) of water for a maximum of 30 minutes. Do not immerse longer than 30 minutes.”
Abbott also says the sensor “can be worn while bathing, showering, swimming or exercising” (Abbott FAQ). In practice, that gives you two numbers to remember:
-
Depth: no deeper than 1 metre (3 feet).
-
Time: no longer than 30 minutes under water at a time.
What about the Libre 2 Plus and Libre 3 Plus?
Abbott’s US pages, which now present the FreeStyle Libre 2 Plus and FreeStyle Libre 3 Plus sensors, give the same 1 metre, 30 minute limit. So does Abbott’s FreeStyle Libre 3 Plus water-resistance FAQ, which adds that Bluetooth performance may be affected while you’re under water.
Can you shower with a FreeStyle Libre?
Yes. A shower is well within Abbott’s limit, so you don’t need to take the sensor off or cover it to keep the water out. Where sensors tend to come unstuck is after the shower, when towels and clothes start pulling at them. A simple routine helps:
-
Keep the water gentle. Let the shower run over the sensor rather than aiming a strong jet straight at it.
-
Don’t scrub over the sensor. Wash around it, and keep loofahs, exfoliating gloves and body scrubs away from its edges.
-
Pat, don’t rub. Pat the area dry with your towel. Rubbing is the easiest way to catch an edge and peel it back.
-
Let it dry before you dress. A damp edge lifts more easily, so give it a minute in the air.
-
Take care with clothes. Pull sleeves and tops on and off slowly so they don’t drag across the sensor.

Can you swim with a FreeStyle Libre?
Yes, as long as you stay within Abbott’s limit: no deeper than 1 metre (3 feet) and no longer than 30 minutes in the water. That covers a lot of everyday swimming, but it’s worth thinking about before you get in.
-
Pools: a dip or a short swim fits the limit. Laps across the deep end, diving and long training sessions can take you past 1 metre or 30 minutes.
-
The sea: waves, sand and salt are harder on a sensor than still water, and it’s easy to lose track of time at the beach. Plan breaks out of the water.
-
Baths, spas and long soaks: the 30 minute limit applies here too, not just to swimming.
Heading to the beach this summer? Chlorine and salt affect adhesive in different ways. Our guide to chlorine vs saltwater explains what each does.
Why sensors come off in water
A FreeStyle Libre stays on thanks to its own adhesive, which holds the sensor to your skin. Water on its own is rarely what ends a sensor early. It’s what water does to that bond over time:
-
Soaking softens the adhesive and the skin beneath it, especially in long swims, baths and spas.
-
Chlorine and salt can dry out and wear at the adhesive edge.
-
Friction from towels, wetsuits, rash vests and swimming strokes catches edges that are already loosened.
It matters because a sensor that’s been knocked off is finished. The sensor filament, the tiny flexible tip that sits just under your skin, comes out with it, so you can’t stick the sensor back on. You’ll need to apply a new one.
Should you cover your FreeStyle Libre?
You don’t have to, but an overpatch gives the sensor’s own adhesive some back-up against water, towels and friction. One thing a patch can’t do is change Abbott’s limit. With or without a patch, the sensor is rated to 1 metre for up to 30 minutes, so be wary of any cover sold as making your sensor “waterproof”. (We dig into this in the truth about patch claims.)
Here’s how the two adhesives work together:
-
The sensor’s adhesive sits underneath, holding the sensor to your skin.
-
The patch sits over the top of the sensor, never under it. Its non-stick centre rests on the sensor, and its adhesive ring sticks to the skin around it, sealing down the sensor’s edges.
Type Strong FreeStyle Libre sensor patches are made for the FreeStyle Libre 2 and FreeStyle Libre 3. Our fabric patches are designed to hold for 10+ days and are water resistant, so they stay put through showers, swims and sweat. Browse the full FreeStyle Libre collection, or compare options in our guide to the best covers for Libre 3 sensors.
Getting the best hold
Start with clean, dry skin. Our guide on how to prep your skin for patches covers the basics. If you swim often or your skin is oily, a skin adhesive wipe can help the adhesive grip; see how to use adhesive wipes to improve CGM and patch wear time. Apply the patch well before you get in the water, so it has time to settle.

People also ask
Can I wear my Libre 3 in the shower?
Yes. Abbott says the FreeStyle Libre sensor can be worn while showering, and it’s water resistant to 1 metre (3 feet) for up to 30 minutes. Pat the area dry afterwards rather than rubbing.
Can I go swimming with my Libre 3?
Yes, within Abbott’s limit: no deeper than 1 metre (3 feet) and no longer than 30 minutes in the water. Longer or deeper swims are outside what Abbott allows.
What can I cover my Libre sensor with?
An overpatch: a patch that sits over the sensor, with its adhesive ring on the skin around it. Type Strong’s fabric FreeStyle Libre sensor patches fit the Libre 2 and Libre 3 and are designed to hold for 10+ days. A patch doesn’t change Abbott’s water limit.
Do I need to cover my Libre 2 when I shower?
No. The FreeStyle Libre 2 sensor is water resistant, and a shower is within Abbott’s limit. Some people add an overpatch so towels and clothes are less likely to catch the sensor’s edges.
How do I protect my Libre sensor when showering?
Wash around the sensor rather than scrubbing over it, pat it dry instead of rubbing, and take care pulling clothes on and off. An overpatch adds a second layer of hold.
