Do Toilet Installatoins Still Use Plumber's Putty

A while back I saw a Bob Villa demo of how to install a toilet with one of those "unifit" units. I noticed that they did not bother to roll a bead of plumber's putty and run it along the edge of the base of the toilet. This is something I have always done. Is this still recommended? Did they just miss it, or is the current standard to skip that step? I will shortly be installing a Toto with a unifit on a ceramic tile bathroom floor. The tiles are those little hexagon-shaped tiles that are about 1 3/4" on a side. The floor is pretty even. So do I go with the putty, or do I just put a nice bead of tub and tile caulking around the edge once I am installed?

Thanks for all that you do! We appreciate it.

The Bob Vila video?
It looked like that plumber had never seen a Unifit.



Once the Unifit is installed, drop the bowl down.
If the bowl is flat to the floor, no movement, then you can put the nut and washer on each side and tighten down.

If not, then take some plastic door shims, and shim at the back of the bowl until there is no movement, then you can put the nut and washer on each side and tighten down.

When that is done, caulk with Clear PolySeamSeal.



Do not use plumbers putty.


Installed and ready to be caulked at the floor.

Plumber's Putty is used to seal sink baskets, but to my knowledge that's about the extent of it. Caulking is used around toilets and sinks, under drop-in sinks, and to seal seams between things like counters and trim.
