How low is a piano?

According to this link, about 27.5 Hz.

About 40” 😉.  The lowest note on a Bosendorfer Imperial is (CCC) 16.5 hz.

I have a DVD of Ray Bryant playing a monster Bosendorfer. video old, scared me, but the sound is AWESOME, whoever recorded that, used 3 mikes along the length of it I seem to remember.

Ray is terrific, I had no idea, inherited it with all the LP's from my friend Roderick.

Is this for regular people, or furries?

this may help in the general question of what falls into what audible frequencies

Depends on the piano and the tune.

My Steinway grand piano is 28 1/8" high from the floor to the top of the white keys.  It will not go any lower, therefore, 28 1/8" is the lowest.

Don't have a Sawsall? 

I’ve heard that the open low string on a upright bass is about 42hz. Does anyone know where the lowest notes on a piano fall
