Test for trap in shower

Categories: Plumbing

I had a guy come to my house and tell me the basement bathroom had no vents so he needed to REDO the entire bathroom, 4200$. I am wondering if there is an alternative. My dad told me that he thinks the original contractors didnt put a trap in the shower therefore the smell comes from the shower. Is there anyway for me to test if there’s a trap in the shower?
