The one thing I would say though Europe isn't as homogenous as the US, particularly when it comes to food and cooking. We've many of the same appliances and manufacturers but things get configured differently in different kitchens and countries.
Also the % in apartments vs houses is a national variation. For example only 4% of Irish households are apartment/condo based compared to quite high % in say Spain or parts of Germany and much higher the further east you go.
Frozen food was a big deal here probably peaking in the 1970s when it was all the range. You'd freezer centre stores selling frozen food, supermarkets had very extensive frozen food sections and home freezing was all the range. There were even books about it.
It wasn't unusual to find huge chest or larder freezers tucked away in garages, ends of kitchens or even in the garden shed.
As things moved towards a foodier outlook frozen food became a lot more about french and chilled in the 90s and onwards and you start to see the growth of 2/3 fridge 1/3 freezer space either top and bottom or side by side.
As for Mrs Bucket, part of the joke was that her house was "in fill" between the much larger home owned by Liz and her brother - it's probable that Liz had a far bigger fridge which she never even thought twicw about as opposed to Hyasinth's high quality, bespoke, bijoux model, deluxe and far superior model, as approved by the best chefs.
