Looking for supply line connectors for my tub filler

Hey all - I'm putting a Porcher Reprise deck-mounted tub filler in my bathroom, and have not been able to find the right sized flexible line to connect to my shutoff.

The Porcher faucet has large, 1" threaded connection points for the lines. Looking at the big orange box store, I haven't seen anything with the right ends on them to connect these to my standard shutoff valves. The lines will be hidden behind the clawfoot tub, but I still want something that a) is of high quality and b) is reasonable looking. Braided stainless lines would be fine - not looking for flexible pipe.

I haven't had a chance to go to my better local plumbing supply place, and thought I'd ask the experts here in the meantime. Should I continue my quest for these lines, or should I instead buy (presumably available) reducers on the faucet connections to bring them down to a more typical size, whatever that may be.

Seriously, it looks like I could thread a garden hose onto the Porcher faucet.

I would get a couple of reducing fittings and be done with it.

I tend to agree, just thought maybe I was missing something. The fittings on the faucet look big enough to use a toilet supply line with - not sure why they made them so big.

They did similar with the shower valve - 3/4 NPT fittings. Had to put 3/4x1/2 reducers on them to plumb. Do people run 3/4" copper to their shower valves?

Is this what you have? Did you try contacting the company to see if they have the fittings you need?

Yep - that's the one. I think the overall size of the connections is to help provide a nice solid mount for the faucet on the deck of the tub - would be a little less solid with smaller pipes.

I'll call American Standard to see if I should have received reducers with the faucet. Not a big deal - would rather just buy them than wait for parts in the mail.

I will say both Kohler and American Standard have been good about sending replacement parts. The Porcher shower valve had a couple of mismatched trim parts (from their Trevi line in Europe) and with no proof of purchase or anything they're shipping me all sorts of trim parts, temp control lever etc.

I figure with a few calls I could get them to ship me a complete faucet kit

I would run with brass reducers and go from there.
