Your plumber’s supply house should have zero issues. It will need to be special ordered, but it it’s available from any to the trade resource. He will likely charge an extra trip charge to assess what parts are needed and then order them.

Home Depot has this kit: 3/8 in. x 20 in. Brass Lavatory Supply Lines with Cross Handle Shutoff Valves and Decorative Trap in Oil Rubbed Bronze and Amazon has certain products including these Kingston Brass CC485 Vintage Straight Bath Supply, 29".

Are you sure you want this kind of sink? It would be a lot easier to install a small vanity as it would cover up all the plumbing mess and you'd just have to add a faucet and drain. Examples:

• Fresca Allier 16" Wenge Brown Modern Bathroom Cabinet with Sink
• Fresca Valencia 20" Glossy White Wall Hung Modern Bathroom Vanity
• Fresca Pulito 16" Small Teak Modern Bathroom Vanity w/ Integrated Sink

I will also point out that the trap shown in the OP's link, and the trap shown in wdccruises's Home Depot link, are known as bottle traps. They are not the same as P-traps and are not code-compliant in many localities. Even if you are in an area where they will allow bottle traps, they are a challenge to install as they have to align perfectly in front of the drain outlet connection in the wall behind them. They do not have the type of offset adjustment that a P-trap configuration provides.

Thanks for the responses! After posting this I did go to our local plumbing supply store. They quoted me about $640 for all the parts in ORB finish, Which honestly is a little more than I was wanting to spend, but might be the best I can find.

WD - I chose this type of sink because the bathroom is a 3.5 x 9 room under a stairwell. Because of a cold air return and the layout of the space the sink is mounted where there's not a lot of room in front of it (picture below). I thought putting a vanity might clutter the space more and make it seem smaller.

Kudz - I think I'll want to use a tradition P trap instead of the bottle. As fun is the plumbing code is I'm not sure I care to pick through it for bottle traps haha!

I am attempting the look in the second picture (just different finish).

Amazon

This kit was $115... there were others ( slightly different color ) and the trap was about $70

Good luck!

I saw this debbi! I don't the the ptrap was a 1-1/2, it was a 1-1/4 which wouldn't work for us. I would definitely do that one if it was the right size!

Your bathroom drain should be 1 1/4" then the trap is usually 1 1/2 with a reducer washer . I didn't look at this one but there were many others...

What Debbi said. Get an adaptor so you can connect the 1 1/4 to the 1 1/2".
