Yes, you can shower at many American Express Centurion Lounges, but availability is limited to specific locations and works on a first-come, first-served basis. High-traffic hubs like Dallas (DFW), Hong Kong (HKG), London (LHR), and San Francisco (SFO) feature dedicated shower suites equipped with high-end towels, L'Occitane or similar premium toiletries, and hair dryers. To use a shower, you must check in at the front desk upon arrival and add your name to the waitlist; during peak travel hours, the wait can sometimes exceed an hour. Each guest is usually allotted 15 to 30 minutes to ensure others can use the facility. In 2026, some of the newer lounges, like the one at Newark (EWR), have introduced modernized "wellness" areas, but it is important to check the Amex app before your flight as smaller lounges (like those in Seattle or Las Vegas) do not have shower facilities. There is no additional fee for using the shower, as it is included in your standard lounge access for Platinum and Centurion cardholders.
