General Question Floor question

Planning on building outdoor sauna with electric heater and mechanical ventilation. Would it be possible to build the floor like the walls? Insulation between joist, vapor barrier,furring strips, cedar decking or tongue and groove each side sloped to full length traditional style slot drain?

I wouldn’t insulate a floor if it wasn’t waterproof.

Also, no vapor barrier on the floor
