How do I bathroom / kitchen / extension? etc.

I’d say yes. We used them for our kitchen - can’t speak for longevity as only been a few months but finish/hardware was good, fitters were impressed (fwiw).

Yay for me, used for various coat hooks etc

We used them for the utility room cupboard doors

Another yes here, bought some lever and wardrobe handles after sussing out where the prices started for solid brass and not shit plated metal and seeing them as the best value and good designs.
Very impressed with what turned up, the box weighed a ton.
I’m a great believer in the TMH mantra from the owners book of “Light, space, nature and materials” i.E the things you touch and they definitely pass the touch test.
