For bathroom and plumbing fixtures and supplies: Rustic in Obuda, on Becsi utca.

For telephone/video/electric hardware (if it's closer than OBI or Praktiker or if they don't have what you're looking for): a small shop at Raday utca 34

For extensive paint selection, there's a shop in Buda: ; and a shop on Klauzal ter. 


Buying hardware in a strange city makes you conscious of the arbitrariness of the way stores lump stuff together back home.  There are very few small, local shops that sell hardware...instead, there are a handful of very large warehouse stores (mostly branches of OBI or Praktiker), and a lot of tiny shops that specialize ... electrical supplies for satellite tv dishes; lighting supplies; paint stores; bathroom fixtures and supplies.  Finding a box of nails near home is a challenge.
