Can I use a 1 1/2" thread pop up drain for a pedestal sink

Hi Idina...

I don't believe they actually make an 1.5" pop-up assembly to begin with... if they do please advise... OK?

All bathroom sinks, including pedestal sinks require an 1.25" pop-up assembly. The drain pipe that connects to the pop-up assembly will usually be 1.5", but some people pipe them up as 1.25" as well...

Any more questions just let us know...

Why are you asking? What's the brand name of your lavatory? What does the drain hole measure? Do you have a 1 1/2"
