It is never stupid to check before working with something that has killed as many people as electricity. I doubt many of them were only working with 24 volts.
You don't need to shut the electricity off, but it wouldn't hurt. You could slip, short the 2 wires together and burn out the transformer. You could also somehow touch the 115V to the transformer.
Depending on what else is on that circuit, it should be easy to just shut off the breaker. How new to the house and DIY are you? If the circuit breakers aren't labeled, it might be a good idea to label them. It might be a good idea to shut down your computer and other electronic things first. More and more of your stuff has battery backups to avoid resetting everything. Maybe replace the batteries first. The bigger ones usually at the top maybe 2 connected together will feed major loads such as air conditioners, stoves, etc. Turn each circuit breaker off, and see what doesn't work. Write it down somewhere. Turn that one on, and turn the next one off. When you are done, you may want to print them out and post it on the lid to the circuit breaker box. Most of them came with number spaces to write things in.
Glad you have your shower drain fixed.

The way the electricians wired our house -- I'm thinking I probably should shut off the power. But if I can avoid it, I'd like to.
