Where can I buy hot water bottle stoppers?

You lose that one thing and you have a useless hot water bottle.

It is the one you normally get from Boots, with a fluffy cover. I had some old stoppers, but these were from the 1970s and don't fit.

The only ones on eBay and Amazon are 'Flashy' types, not sure if these hw bottles are or not, and it suggests they don't fit other types.

I would just go and buy another hot water bottle. I don't think the stoppers come in a standard size and you don't wanna be scalding yourself if you have a leak!

I would give up on using a hot water bottle and use a microwaveable wheat bag instead. Much less faff.
