Does the Wheel Well Tank go Above or Below Subfloor?

Hello… Hello… Hello

I’ve just ordered a 39 Gallon Wheel Well Tank. I’ve been trying to figure out if I should secure and install the tank before or after doing the Subflooring. I’m concerned if I install directly on the metal, the water could freeze in the tank at colder temps but if Install after the subfloor, it won’t properly fit the wheel well anymore.

The wrench is, the Tank is on back order weeks longer than desired & I am at the stage of being able to begin the floors. I’ve been looking everywhere for an answer & haven’t had any luck. Until… Now???

Greetings & Welcome!

I would do the subfloor & insulation, as well as the walls with insulation & wiring before the water tank.
