I'm flying BOS-ZRH-TXL in a few weeks on LX and have a J seat. This is my first time flying LX and my first time at ZRH.

My layover is 1:50 and I will desperately want to take a quick shower. Should I use the Swiss Arrivals Lounge or the Swiss Business Lounge?

My understanding is that the arrivals lounge has more showers, meaning I won't have to wait. At the same time, the business lounge would be closer to my departure gate.

Any suggestions?
