Exposed Pine Floorboards in Bathroom (or hardwood)

Possom1

I was considering the option of using exposed pine floorboards in a bathroom, and wondered if that is a reasonable option in terms of the boards not becoming rotten due to damp.

I'd use tongue & groove pine boards with the grooved out tracks under them to prevent cupping. Joints and any gaps would be filled with silicone sealant.

The floor would then be sealed with Ronseal Diamond Hard Floor Wax (pictured), which I read about on the following ScrewFix threads:

The bathroom will contain a bath with an overhead bath shower and a glass bath screen. (Obviously it's not a wet room).

Or perhaps exposed pine is just a bad idea, so what if the floorboards were instead some other type of wood and then also treated with the pictured product? Perhaps a hardwood of some type (I don't know specifically what)?

Have a tiled floor in a bathroom with a bath and shower. But upstairs shower etc and this floor is just standard deal t&g flooring. Using a mat, that absorbs most splashes from people drying themselves. We stained the floor with one of the eco stains and then waxed. It's lasted well enough for a dozen years or more.
