Best Hot Water Bottle
I just love Pauina 🥰 I can't imagine my daily life without her anymore, and she's just so uncomplicated. So happy and grateful that I found her through a dear friend, and especially for us endometriosis sufferers, she's a game changer.

Sarah Aldenhoff
Game changer
I got the Pauina twice – now I have one by the bed and one by the couch (incl. charging options). I use it several times a day and even take it to work with me. For me, with endometriosis, it's an absolute game-changer.

Can also be operated with one hand
I ordered it for my wife. We both think it's great. My wife has tenosynovitis in her right thumb. Her hand was immobilized. Filling a hot water bottle with one hand doesn't work. A solution was needed. Here we found a really good replacement. I would buy it again.
Aurelia
Real hot water bottle without boiling water
I often need a lot of warmth. I even took it with me on a trip and heated it up on the ICE, which wouldn't have worked with a conventional hot water bottle... I love the PAUINA. Thank you for that.
Sarah Weissbeck
Perfect hot water bottle, not just for me 😍
Connect it quickly and it's already warm. Then wait until the light goes out and you have hours of warmth 😍 no boiling water or strange rubber smell.
My cat also always comes right over and enjoys the warmth ❤️ I would buy it again and always recommend it!
Mareike
Thoughtful design, but could be a bigger pillow
I would like an XXL version of the hot water bottle without a belly strap. The area is a bit small for me, especially for the back or feet in bed. Otherwise, it's a good hot water bottle.
Dear Sir/Madam,
I love this hot water bottle!
I suffer from endometriosis and adenomyosis. This hot water bottle has made my life much easier. It gets very nice and hot and stays warm for a long time. I can also operate it directly from bed, which makes my painful life much easier.
Nicole Weiss
Best decision! Highly recommended!
I discovered the hot water bottle on TikTok. A lot of junk is advertised there, but when I saw this hot water bottle, I had to visit the PAUINA website. I was immediately convinced and bought one! Now after using the hot water bottle, because I also suffer a lot from abdominal pain, I recommend it to all my friends and family! And I recommend it to you too! Once plugged in, it heats up within 5 to 10 minutes and stays warm for 5 hours until it cools down again. The free belt that comes with it, for hands-free carrying of the hot water bottle, is great for the stomach!
Katja Giuseppino
So beautiful
Simply practical, quick to put on, and functional. I can do household chores and always have the hot water bottle with me, keeping my hands free. I strap it on and I'm done. I also don't burn my hands with hot water because it's electric. It charges quickly and stays warm all night. I immediately bought another one for my two children.
Emanuelle Luisa Lober
Simply perfect - my new favorite hot water bottle!
The Pauina hot water bottle is simply fantastic. The design is not only modern and appealing, but also super practical. It retains heat for an extremely long time and provides pleasant, even heat distribution – ideal for cold days, muscle tension, or period pain.
The material is also very comfortable on the skin.
I use it almost daily and am completely satisfied! Absolutely recommended!
Tanja Wroblewski
Love - I wonder what I did without it before...
I bought the hot water bottle in October 2023 and can't live without it anymore... The hot water bottle heats up super fast and stays warm for a very long time. It's perfect for me, as I'm always cold. Even in summer at 30 degrees 😅 So it would be practical for me if, in the future, it could also be charged in the car or via a power bank when there's no outlet nearby. (Especially when you're on the go)
