Do I need hide anymore?

In my experience is that are around the hide and not in it and leave it soon after you put them I'm it then the heat could be building up to hugh within the hide. Use a thermometer/temp gun to test and if the heat is just right that wI'll more than likely stay in it. I have also learned if the hide is to tall or large they don't feel secure and will constantly leave it seeking out refuge. When I replaced a hide for one of my girls with a smaller darker hide now she never leaves it. Good luck friend

Exactly...just because a snake rejects one hide doesn't mean it doesn't want & need a good hide, it might just mean you got it wrong. Hides aren't only
about their privacy (like they have more of in a rack), but also about "back pressure", the feeling they are squeezed into a cave where no predators can
sneak up on them. Some commercial hides are a better fit than others, & when they aren't right, I make my own. All my snakes use them, always have.
Snakes don't like high ceilings, large doorways, or "open floor plans".

I keep my bp in a tub in a dark corner of my room with small amount of natural light coming through, so it is similar to a rack but without a rack?

Even so, he uses his hides. There are fake plants in the tub and enough aspen for burrowing if he wants to but he prefers the hides which are identical. I have offered different shaped hides and he did not use them, so his preference are the round bowl types vs square shaped types or high 'ceiling' types. Having something touching their sides if not the top, makes them feel secure, so even if the hide is not used, the snake is still touching them when hidden behind it or near it. But I think you should try other hides to see what works.
