Hello Malinda! 
I’m glad you’ve found your way here 
For me, I just kind of…did? I mean, I started exploring this path as a young girl (12-13 years old, pretty much) and never really stopped. When I first found Wicca, I told my mom who, at the time, was pretty dead-set against it. She told me it was the work of the Devil and she wasn’t comfortable with it in her home. Fast forward many years later (I’ll be 30 this year) and now we’ve done spells together, I’ve made her prayer shawls and tinctures and salves, and she’s pretty okay with it. We even still live in the same house 
It’s funny how that works, but I’m glad it did. I mean, I even have an entire website and YouTube channel dedicated to my path and practice and sharing what I know and she doesn’t bat an eye.
I think it comes down to knowing your family and who you plan on telling. If you think they’ll react negatively, then you don’t have to tell them. I think personal belief systems are okay if kept private.
Also, you don’t have to take ritual baths. I posted an Elemental Ritual Bath 
for one of our challenges, but it could easily be adapted for a shower! Just go with what you’ve got, adapt and change where needed
