I'm in urgent need of help with my bathroom remodel. I feel overwhelmed. Any suggestions?

I recently inherited this house. While it’s old, I admire the wooden walls and the overall rustic feel. As a single mom on a very tight budget, I have limited funds to spend. I’m wondering if there’s anything I can do to improve the bathroom's appearance without making any drastic changes. I painted the dingy yellow bathtub white, but other than that, I’ve only removed the hideous wallpaper. 😵‍💫
