Many factors to be considered, and more info needed. What is finished floor material would be the main one, is finished floor height to be a factor, size of area to be heated? I normally use 120 electric, set in self leveling compound in bath floors, never an issue.

This. :thumbsup:

You can't simply ask what's better, 120 or 240V.

For me, the size of the mat is the typical deciding factor if 120 or 240v. Unless I have a close by 240V heating circuit, then I might tack it onto that.
Many that I do are only 20-30 sq/ft, so I will sometimes put it on the room's lighting circuit, or even the receptacle circuit if a really small bath or something like a bath that is not near any bedrooms.

I prefer to use the voltage best fit for the application.
