What should I do if there is a foul smell coming from my shower drain?

If there is a foul smell coming from your shower drain, you should try pouring a mixture of baking soda and vinegar down the drain to help eliminate the odor. You can also try using a drain cleaner specifically designed to remove odors. If the smell persists, it may be a sign of a more serious Plumbing issue, and you should consider contacting a professional plumber for further assistance.
