Best rubber hot water bottles for cozy pain relief

Which rubber hot-water bottle is best?

There’s nothing like a warm substance for soothing aches and pains, and a filled rubber hot-water bottle is one of the older and most trusted methods of accomplishing this. In fact, some rubber hot-water bottles can get and stay too warm; in which case, it’s smart to purchase a rubber hot-water bottle that includes one or more knit covers.

What to know before you buy a rubber hot-water bottle

Materials

Aren’t rubber hot-water bottles just made of rubber? Yes, some are, but others use thermoplastic instead.

  • Rubber: Two important factors to note concerning rubber hot-water bottles are: Rubber hot-water bottles are thicker than plastic — and thus take longer for the heat to make its way through — and people with latex allergies should avoid rubber hot-water bottles entirely.
  • Thermoplastic: Thermoplastic bottles have a few pros and cons compared to rubber. They’re usually thinner and slightly transparent, which can make it easier to see the water level and for heat to transfer faster, but they also increase the chances of leaks, ruptures and tears. Thermoplastic is also safe for those with latex allergies to use.

Covers

Extended exposure to heat of any kind opens you up to heat-related injuries, and rubber hot-water bottles are no exception. This is why so many rubber hot-water bottle options include a cover to add a protective layer without limiting the transfer of heat you need from your rubber hot-water bottle.

What to look for in a quality rubber hot-water bottle

Size

Child: Child-sized rubber hot-water bottles contain less than 1 liter of water and are, as you may have guessed, designed explicitly for use by children. To prevent harm to children, these bottles also intentionally dissipate heat more quickly than other bottle sizes.

Mid-size: Mid-sized rubber hot-water bottles actually cover a large range of sizes: anything between 1 and 1.75 liters, to be exact.

Standard: For large heat-soothing needs, you’ll need a big rubber hot-water bottle. These standard (more like large) sized rubber hot-water bottles can hold up to 2 liters of water and are big enough to completely cover the abdomen or any similarly sized area of the body.

Surface types

Rubber hot-water bottles are available in more than just flat surfaces, and each type of surface actually serves a specific purpose.

How much you can expect to spend on a rubber hot-water bottle

Rubber hot-water bottles are not only easy to manufacture, but they’re also fairly cheap to manufacture. These facts combine to allow you to find top-tier rubber hot-water bottles that cost less than $10. That doesn’t mean you can’t find expensive options that cost more than $20, but it does mean you’re likely paying for something else instead of just the rubber hot-water bottle.

Rubber hot-water bottle FAQ

Is it safe to sleep with a rubber hot-water bottle?

A. That depends on the location of your rubber hot-water bottle. It’s perfectly safe as long as it’s used to warm the lower area of your bed, where your toes rest. If you place it higher than this, you’ll add a big risk of rolling onto it in your sleep and causing it to pop. Depending on how hot your water still is, that can cause some serious harm.

What’s the best way to keep the inside of a rubber hot-water bottle clean?

A. Keeping your rubber hot-water bottle clean is one of the easiest tasks you’ll ever have to complete in life. All you have to do is make sure it’s empty and left hanging to dry between uses. Remember to not use any cleaning substances, because most of them can actually damage the rubber.
