About the maker: We design our blanket and textile collection from the Welsh Otter studio just outside Llandeilo in South Wales. To us, heritage is at the core of our designs - but with a modern twist for the contemporary home. We are inspired by vintage carthen and Welsh tapestry patterns, as well as traditional materials and techniques. We work with woollen mills and artisan makers across Wales and the UK to bring our designs to life. Sustainability is at the core of all our products - biodegradable materials are used and sourced locally where possible, and non-plastic packaging is used to deliver your final product.


Hot water bottle safety
Hot water bottles can be dangerous & cause burns if they are not cared for or used in the proper way. Please read our guides for filling, using and caring for your hot water bottle below.


1. When filling your hot water bottle, do not use boiling water. Once the water has boiled allow it to stand for a couple of minutes before filling your bottle. Filling a bottle with boiling water can cause splash back, which may cause burns.

2. When filling your bottle hold the bottle by the neck in an upright position and fill slowly to avoid water splashing back.

3. Only ever fill your bottle to a MAXIMUM of two-thirds capacity.

4. ALWAYS expel air from the bottle by lowering it carefully onto a flat surface until the water appears at the opening.

 5. Screw the stopper sufficiently tight to ensure there is no leakage. Finger tight should be adequate.

6 Hot water bottles should always be filled by a responsible adult.


1. DO NOT sit, lie on top of or put excess pressure on your hot water bottle.

2. To prevent burns occurring use a cover on your bottle and avoid leaving it in contact with one area of the body for more than 20 minutes.

3. Only use a hot water bottle to warm up your bed. Take it out before you get in. This helps to avoid accidental burns.

4. The use of hot water bottles by babies is not advised and children should be supervised.

5. People with sensitive skin or reduced feeling should use hot water bottles with care.

6. Hot water bottles can be dangerous and cause burns if they are not filled, cared for or used in the proper way. ​

7. Please follow the instructions given.

8. All our bottles are made with natural rubber, so please be careful if you have a latex allergy.

All our bottles are manufactured to British Safety Standard 1970:2012 and come with a guarantee against manufacturing defects. 

It is advisable to replace your rubber bottle every 2 years to ensure that you are always using a bottle which is in good shape and safe. Rubber naturally deteriorates overtime and this natural process can be affected by how it is stored and used.

Hot water bottle

I bought this water bottle as a gift for my mum for christmas. She said it was nice and soft and maintained its heat for a long time. Love the colour as it goes with her blanket. Thank you so much. I will definitely purchase again.

Beautiful hot water bottle cover

As always, it’s a joy to receive a parcel from Welsh Otter; beautiful, simple packaging and a wonderful warm, wool hot water bottle cover in a gorgeous colour inside. It makes getting into bed on a cold night really toasty!
