European size, my plumber got to charge me lots extra to find the adaptors.

Good quality... It fit the sink/plumbing just right and looks very nice and classy under an exposed ADA sink counter top.

Don’t place this where you might bump it often since the horizontal and vertical pipe connection is not stable. The fixture will tilt creating a positive slope (points upwards) which means your sink will not drain until you adjust it. But it is attractive. Classic example of form over substance.

Great quality and matches perfectly with our faucet.

Matches the fixture - didn’t nessicarily need this but it looks the best to have all the finishes matching and my exposed pipes made it essential for me.
