In the garage that Richard Weeks posted a picture of today.  

Where did you actually see it first to decide you wanted it?

If you have a local Ferguson plumbing supply, they can find anything...

I'm with Susan Haughton -- Fergusons here in Charlotte can typically find most anything.

Everyone need to learn to be flexible in their demands. There comes a point when the time spent is posing a non-recoverable expense.

The manufacturer's website(MOEN etc.)

consumersplumbing  menards tileredi I can order for you wholesale if are stumped  Are you going to lay tile over this or want it finished?

Sally K. & David L. Hanson - frankly, I'd stop at Google or Amazon only!

Find out who made it and google it. Then find out where the nearest retailer is, or try to buy it direct. 

Pull out the yellow pages and call every plumbing supplier in town, if it exists then one of them may know.

I have no better suggestions - sounds like Susan Haughton has a good one. Perhaps Lowe's? Home Depot?

Sally K. & David L. Hanson I would do exactly what you did. Ask in the Q&A of ActiveRain. You get lots of answers and you get points!!

Keep us posted.

Actually, I would cheat.  My daughter in law used to work for a large plumbing supply. I would as her for her connections

Good Question....

Perhaps an antique store, wreckage yard, recycling yard, someone's basement, garage sale...

It has to be somewhere! ...but I don't know where.

I hope you do find it, Sally K. & David L. Hanson. We had a Corian version of that installed years ago. Not sure they still make it though. 

Maybe a specialty store?  I'd also try Home Depot, Lowes and HD Builder's Supply.  Online has more stuff than the stores do.

Bell Plumbing in Denver would have it.

Keep us posted Sally. It will be a good source for all!

Ha! It's in my bathroom!  I got it from a DC plumbing supply store called Plumbing Parts Plus.  They are better than Google any day.  If you come to Rockville, MD to their showroom, I can show you around DC!

Sally K. & David L. Hanson - we have a large plumbing supplier here in Charlotte that sells commercially but, if we need something like that, I just have one of my contractors pick it up for me there.  Search for local commercial plumbing supply houses (not Fergusons as their more for public consumption).  You can always locate it and ask if they'll sell to you independently as well.  If not, have your contractor pick it up for you once you've located it.  Good luck!

call a Kohler supply company....

Sally,

Call Koeler direct and find out who they distribute to.  A

A local plumbing store for sure.  I'd also likely call my plumber and/or contractor and ask if they knew where I can resource it. 

Why not have a custom tile pan put in? In OKC, only fiberglass pans are used if a custom tile is not put in.

I bet you are just not googling it correctly. I've had to do this for storm door parts, dryer parts, etc.  Trick is to get the correct name or part # then it's smooth sailing.

I would visit one of our area's specialty plumbing stores.   

Susan Emo nailed this one!

The Noland website.

Amazon? 

Amazon would be a first stop or the manufacturer's site!

Sally K. & David L. Hanson I would check with the manufacturer and take a look on Amazon.

I agree..our local Fergusons can locate anything!!

plumbing supplier.

I only go to bing - I avoid G at all costs these days - completely irrelevant search results based on your tracking history

no idea

I would check with the manufacturers web site. If i did not know who manufactured it. Then may have to go back to where i saw it to get a picture and bring to my local plumbing supply company

Dixieline, Pacific Sales, Home Depot, Lowes, Orchard Supply and any local specialty shop in my area. Great way to start a conversation with a local business.

I go to Home Depot or call my plumber to find it. Done
