These counter-top ones? Not that I'm aware of. I have a normal (though half-width, but that just makes sense for a 1 bed place really) one in London.

Maybe older builds that haven't been updated wouldn't have any space for one as you say, without re-jigging cupboards, so maybe people do. But then you're losing work surface for it..

My view on the utility of those devices :

I lived in Paris for a while. Large appartement have dishwasher, but in single units, it’s uncommon.

I remember looking for solution like that for a renter in a small place without proper plumbing to accommodate a dishwasher.

I also see a market for the so called tiny house folks or full time RVer.

I don’t find that particular product appealing too much, but I would like to see more like that. And I know folks around me that would buy one if it’s was more open and fixable.

I've rented.....8 houses so far, all in North East(Newcastle) and every single one of them had a dishwasher. I suppose maybe part of it is that I simply wouldn't rent a place without a dishwasher ;-)

presumably "houses" is the key word here?

Fair, but in my experience with the UK something like a 2 bed house is really just an apartment cosplaying as a house.

Well in a lot of places, the fact it is a self standing property means the owner can do whatever they want with it without having to consult a "building committee".

Like rearranging plumbing/electrical however you want.

Whether landlords use this advantage for tenants quality of life is a whole other story.

I've rented flats outside london for years, always come with a dishwasher. I'm on a high salary though, so it may skew my world view of what is "standard"

Anecdata: I've rented 2 flats in London over the last 30 years (and been a frequent visitor to 4 more); none had a dishwasher. Rented one house in Newcastle; also no dishwasher.

Every place I've rented in London had a dishwasher, and we're talking 6 places over 15 years
