Victorian plumbing have loads of black bathroom fittings. https://www.victorianplumbing.co.uk/bristan-prism-inline-dual-control-shower-pole-w-diverter-kit-black https://www.victorianplumbing.co.uk/taps?FT=5013&filtSeq=Colour&Sort=BS Matt black seems pretty popular at the moment so I'm sure other online bathroom stores may sell them too. Victorian plumbing is reasonably priced too, as I've been looking and comparing lots of sights and prices for my own bathrooms. Good luck :)

Hi Hannah, I think you are right and I do not think the stainless steel hardware will do the kitchen justice. Brass on dark green units works beautifully and it will also help to give the kitchen added charm and character. This will still work with the stainless steel handles on the appliances but one thing to watch is the finish on your tap, if you are going with brass hardware then I would also go for a brass tap.

Victorian Plumbing have a selection

I like black (we've planned black) but I think it only works with a strong colour...the overall vibe needs to be modern.  Sage green is quite pale isn't it? More of a gentle modern country vibe perhaps? I would imagine the nickel would be much more suited in this instance.
