Let me start by saying that I am a commercial plumber and have not had previous experience with this line of residential bathroom faucets, but you guys may have seen them before, or even installed them.
On this page, , at the top right, the Catalina Lavatory Pull-Out.
This thing is freakin' awesome!! I installed two of them yesterday in my house and my wife wanted to jump my bones when I was done. And that is rare being married for 15 years.
Anyway, it is a standard 4" spread installation and comes with a new pop-up too.
No, I don't work for them (I think they are owned by Black and Decker). Just thought I would say something nice about what seems to be an excellent, reasonably priced residential product.
