You’re at a high risk of falling in the shower, which can require medical assistance. Those falls are also more likely to cause injury than falls anywhere else.1 Being able to take your medical alert device with you in the shower is one of many reasons you need waterproof medical alert devices.
Water resistance is one of the aspects we assess when testing medical alert systems. We submerge our devices in water and take them with us in the bath. Then, we test to ensure they remain fully functional. Bay Alarm offered us the best waterproof medical alert devices, closely followed by Medical Guardian and ADT Health. Read more to learn about them.

We brought our Bay Alarm Medical SOS Smartwatch swimming so we could press the SOS button on the side if we needed help.

Everything about Bay Alarm Medical is easy. When purchasing our system, their website clearly showed our options and how much each one costs. Once it arrived at our doorstep, getting our system up and running only took about 15 minutes. Using it on a daily basis couldn’t be any simpler either.

We bought a Bay Alarm Medical SOS Smartwatch so that we could test Bay Alarm’s most water resistant device.
While all of Bay Alarm Medical’s wearable devices offer some amount of water resistance, they’re not all equal. They all worked after we showered while wearing them, but some we needed to take off before hopping in the pool.
More specifically, the SOS All-In-One and the GPS Help Button only received an IPX6 rating whereas the SOS Micro and SOS Smartwatch received an IP67 rating. The second number in those ratings refer to the water resistance of the device with the six meaning it can withstand being sprayed with water, but cannot be submerged, whereas the seven means the device can be submerged in three feet of water for up to 30 minutes.
Did You Know? A seven rating for water resistance on the IP scale is as high as you’ll get for a medical alert device. That’s largely because these devices require a pushable button and movable parts are difficult to make fully waterproof.
For offering some of the best equipment in the industry, Bay Alarm does it at surprisingly low prices. They’re one of the most affordable options, especially for couples since they offer monitoring for two devices at the same price as monitoring for one. Here’s an overview of Bay Alarm Medical’s pricing:
| System | SOS Home | SOS All-In-One 2 | SOS Micro | SOS SmartWatch |
|---|---|---|---|---|
| Upfront Costs | None | $149 | $149 | $199 |
| Extra Alert Button | $39 | Not available | Not available | Not available |
| 360° Bundle | Not Available | +$10 per Month | +$15 per Month | +$15 per Month |
| Fall Detection | +$10 per Month | +$10 per Month | +$10 per Month | +$10 per Month |
| Cellular Support | +$5 per Month | Included in Base Price | Included in Base Price | Included in Base Price |
| Base Price Per Month | $24.95 | $34.95 | $34.95 | $39.95 |
Industry Comparison: Bay Alarm is not the only medical alert system that costs under $25 per month. Lively also offers a plan for their mobile device that costs $24.99 per month, although you need to pay for the device upfront. Check out our Lively price guide and Lively review for all the details.
The pendant that came with our Bay Alarm SOS Home system is water resistant so we could take it with us in the shower.
Where Bay Alarm’s usability really stands out is with their mobile app. Caregivers can see the location of their loved one clearly displayed on a map with a pin showing their location. That’s typical of a caregiver app, although when we tested MobileHelp, we found out that some providers limit the amount of times you can check up on your loved one’s location. Bay Alarm let us check as often as we wanted.
That’s not all, though. Bay Alarm’s mobile app lets caregivers manage every aspect of the user’s account. It let us check our purchase history, change emergency contacts, and add home entrance details for first responders. This makes it so your loved one doesn’t need to worry themselves with all the technical details of their medical alert system.
The rest of the system takes a similar approach where the responsibility of the user is minimal enabling them to receive as much help as they need to manage the system.
| Connectivity | Landline and cellular |
|---|---|
| Fall Detection | $10/month |
| In-home Range | Up to 1,000 feet |
| Battery Backup | Up to 32 hours |
| GPS Option | Yes |
| Money-back Guarantee | 15-day |
If you’re looking for an at-home system you can still use when meandering through your garden or lounging on your back porch, Medical Guardian should be at the top of your list. Their at-home systems feature an impressive 1,400-foot range and all of their wearable alert buttons are at least water resistant.
Unlike with Bay Alarm Medical, every wearable Medical Guardian device is IP67 rated. That means you can take them in the shower or swim with them. As a reminder, we could only swim with some of Bay Alarm Medical’s alert devices since they were only rated IPX6.
Medical Guardian’s MGMove charged us extra if we wanted to access the Messages & Reminders feature.
Regardless of which system you want, expect to pay for the equipment upfront or finance it with Medical Guardian. No free equipment here. If you’re looking for free equipment, Bay Alarm Medical offers their at-home system with no upfront fees and ADT offers all of their systems with a flat $99 activation fee but no cost for equipment.
We understand why Medical Guardian charges for their equipment, though, because it’s some of the best in the industry. They made our list of the best medical alert smartwatches and the best medical alert necklaces. Here’s how much Medical Guardian charges for their equipment and services:
| Medical Alert System | MGHome Landline | MGHome Cellular | MGMini | MGMini Lite | MGMove |
|---|---|---|---|---|---|
| Equipment Fee | $149.95 | $149.95 | $149.95 | $149.95 | $199.95 |
| Shipping Fee | $12.50 | $12.50 | $12.50 | $12.50 | $12.50 |

| Fall Detection | +$10 per month | +$10 per month | +$10 per month | +$10 per month | +$10 per month |
| Price per Month | Starts at $27.95 | Starts at $34.95 | Starts at $36.95 | Starts at $42.95 | Starts at $38.95 |

Medical Guardian’s app is functional, but we think it could use a redesign to make it more user friendly.
Don’t expect a Bay Alarm quality mobile app from Medical Guardian. It’s still functional, but not nearly as easy to navigate and you cannot easily outsource all of your account management to a caregiver. Caregivers can still check the location of devices they manage, though. Check out our Bay Alarm vs Medical Guardian guide for an in-depth comparison.
What made Medical Guardian easy for us to use was its impressive range. That 1,400-foot range meant we didn’t need to worry about our device disconnecting when we swam in our backyard pool. It also allowed us to install our base station anywhere we wanted in our house since the range was not a limiting factor. Range limitations on other systems meant needing to install our base station in the middle of our house.
| Connectivity | Landline, cellular, and Wi-fi |
|---|---|
| Fall Detection | $10/month |
| In-home Range | Up to 1,400 feet |
| Battery Backup | Up to 32 hours |
| GPS Option | Yes |

Bathrooms can be dangerous. They present a lot of hazards from slippery floors to heat that can cause a loss of consciousness.2 ADT’s wall-mount medical alert button offers IP67 waterproofing and works with their at-home or on-the-go system with no upfront costs. Most providers only offer wall-mount medical alert buttons with at-home systems.
We already mentioned that ADT Medical’s wall-mount alert button is IP67 rated, which means it can be submerged in water; not that you’d need to. We recommend putting one up in the shower or near the tub for easy access. Don’t go putting it in the tub, though.
All other ADT alert buttons are IP67 rated as well. This means users do not need to think about whether or not they’re wearing the right alert button for any activity. With all buttons rated at IP67, you can take any of them with you everywhere you go.
FYI: During a medical event, you can become cognitively impaired. That’s when having a large, wall-mounted help button becomes useful. You don’t need to think about where it is or how to untangle it out of your clothes. All you need to do is hit the big button on your wall and help will be on the way.
The pricing for ADT Medical is a bit deceptive. They say their equipment is free, but they tack on a $99 activation fee for all of their systems. To us, paying that $99 activation fee felt like paying for the equipment itself.
Either way, $99 is an affordable price for a medical alert system considering Medical Guardian’s systems start at $150. Here’s a complete breakdown of ADT Medical’s prices:
| Medical Alert System | Basic | Plus | On-The-Go |
|---|---|---|---|
| Activation Fee | $99 | $99 | $99 |
| Wall-Mount Button | +$2.99 per month | +$2.99 per month | +$2.99 per month |
| Additional Pendant | $14.99 upfront + $5 per month | $14.99 upfront + $5 per month | Not Available |
| Fall Detection | +$11 per month | +$11 per month | +$11 per month |
| Monitoring Fee | Starts at $26.99 per month | Starts at $34.99 per month | Starts at $ 36.99 per month |
Compared to Bay Alarm and Medical Guardian, ADT Medical takes the opposite approach to usability. Instead of packing an app full of features, they don’t even have an app. There’s just the medical alert system you buy. To set it up, we called ADT to activate it. After that, there was only one button we ever needed to press and that was the help button on our pendant or wall-mount button.
This approach surprised us, because when we tested ADT’s home security system, we had the exact opposite experience. It was filled with technology and they make one of our favorite home security system apps. We think this is something they should add to their medical alert system, even if just for caregivers.

| Fall Detection | $11/month |

AARP members can save over $150 when buying a Lifeline medical alert system. That’s through free shipping, free activation, and 15 percent off an annual subscription. Or, you can get an at-home system for under $100 upfront including your first month of monitoring. Those are the best discounts on medical alert systems we’ve seen through AARP.
Every Lifeline device with a help button on it, aside from the base station, can be fully submerged in water for up to 30 minutes. We like that consistency. It makes it easy to know your device’s waterproofing without needing to look up the specific model.
If you looked at Lifeline’s website, you might think they only offer three systems. But, the Home and Mobile Systems both have two different system types for a total of five systems. That can make it tricky to compare their prices, so we made a Lifeline pricing table comparing all your options:
| System | Home Landline | Home Cellular | On the Go Standard | One the Go Mini | Smartwatch |
|---|---|---|---|---|---|
| Device Fee | None | None | None | None | $159 |
| Setup Fee | $99.95 | $99.95 | $99.95 | $99.95 | Free |
| Shipping Cost | $29.95 | $29.95 | $29.95 | $29.95 | $29.95 |
| Fall Detection | +$15 per month | +$15 per month | +$15 per month | +$15 per month | +$15 per month |
| Key Lockbox | Free | Free | Free | Free | Free |
| Monthly Fee | Starts at $27.95 | Starts at $34.95 | Starts at $39.95 | Starts at $44.95 | Starts at $34.95 |
Pro Tip: AARP members get $50 off of their Setup Fee through the free activation promotion. That means you won’t get that discount when buying a Lifeline Smartwatch since they label the upfront cost as an equipment fee instead of a setup fee.
We were able to have our Lifeline system fully set up and functional within 10 minutes of it arriving at our house.
Setting up a Lifeline alert system couldn’t be easier. It only took us four steps and one of those steps was taking everything out of the box they shipped our equipment to us in. Our setup only took about 10 minutes total.
After that, we also set up the Lifeline mobile app which provided nearly as much functionality as the Bay Alarm mobile app for caregivers. However, we still preferred the Bay Alarm mobile app. Our Lifeline app was slow to refresh and missed notifications from time to time. Aside from the mobile app, though, using our Lifeline system to request assistance was simple.

We don’t run a lab for testing an electronic device’s waterproofing, so we relied on the International Electrotechnical Commission’s (IEC) IP rating.3 They conduct third-party tests on electronic devices of all kinds to determine their water resistance. After finding out which medical alert systems offer water resistant devices, we bought 10 systems and tested them out. We assessed each system based on the following criteria:
While those are our main criteria, our team of senior care experts look at every aspect of a system that can help keep a senior safe during a medical emergency. After using each system in our own home, we reach out to industry experts and real customers to get a full picture of the quality of each system before we make our recommendations.
We appreciated the sleek design of the Bay Alarm SOS Smartwatch.
An IP rating has two numbers that tell you how dustproof and waterproof a device is. The first number is the dustproofing and the second number is the waterproofing.
Most wearable medical alert devices have a six or seven rating for waterproofing. A six in waterproofing means it can withstand water jets from any direction. Think of a water jet as taking the device out in the rain or in the shower. A seven means it can be submerged in up to 3.3 feet of water for up to 30 minutes. These devices allow you to take swimming.
As for dustproofing, most devices either have a 6 rating or a rating of X. A rating of six means it’s fully dust-tight so that dust cannot cause issues with the device’s electronics. An X, on the other hand, means the device has not been tested for dustproofing.
We bought the Medical Guardian MGHome Cellular which includes a waterproof help button pendant.
We highly recommend choosing a medical alert system with at least a wearable waterproof device. Here’s why:
Everyone could use a waterproof medical alert system. It just depends on how waterproof you need your medical alert system to be.
For people who swim or do other water activities, we recommend a wearable device with an IP 67 rating such as the Bay Alarm SOS Smartwatch or any Medical Guardian, ADT or Lifeline system. If you only need a device to take with you in the shower or out in the rain, you can opt for any Bay Alarm device, even the ones with a IPX6 rating.
No, not every medical alert system offers waterproof devices, but most providers at least offer some wearable devices that are water resistant. If the device has a built-in speaker or microphone, odds are it is at most water resistant.
You can only swim with your medical alert device if it has an IP67 rating. That means the device can be submerged in up to 3.3 feet of water for up to 30 minutes.
It’s a bit of a misnomer to call a medical alert device waterproof. If you submerge any medical alert device deep enough into water, it will spring a leak. When a medical alert system says a device is waterproof, they mean it has an IP67 rating so it can withstand being submerged in 3.3 feet of water for up to 30 minutes.
No, some of the most affordable medical alert systems offer waterproof devices. For instance, the Bay Alarm Medical SOS Home system includes a waterproof medical alert pendant and only costs about $25 per month.
Generally, medical alert devices with built-in microphones or speakers are not going to be waterproof. But, to know for sure if a device is waterproof, you need to look up its IP rating. Any device with an IPX6 rating can be taken in the shower or the rain and devices with an IPX7 rating can be submerged in water.
