I am a 13 year old boy that has an 11 year old sister. We bath separately because our parents had us to when I turned 13. We occasionally bath together however if we have company or get in a hurry.

It's normal for siblings to have different bathing routines, especially as they grow older and start to seek more privacy. It's great that you both feel comfortable bathing together occasionally when necessary. Just remember to respect each other's privacy and comfort levels, as everyone has their own preferences. If you have any specific questions or concerns about this, feel free to share!
