Did they close their store on Millburn Ave. near Trader Joe's?

Yes 

They were part of NJ Plumbing Supply on Newark Way in Maplewood, which I see is unfortunately also closed.  

It kept saying "closed for inventory." So where do we go now if we need a new bathroom?

NJ has reopened under new management.  Still the go-to place for the pros

Is it still smokey in there?

I believe our newest advertiser is has taken over that location on Newark Way:

South Amboy Plumbing Supply
