His right shoe fell off the ledge. It got lodged behind his locker. A team trainer had to attach a coat hanger to a long piece of string to fish it out. It was all very complicated. And then the Wizards lost the game. Neither Sessions nor his teammates sounded broken up about leaving Sleep Train Arena for the final time.

“Hopefully, the new locker room will be better,” Sessions said.

The N.B.A. regulates stuff as much as the Federal Reserve. Each playing surface must measure 94 feet by 50 feet. A traveling violation in San Antonio is the same as a traveling violation in Cleveland. Quarters are 12 minutes long. In other words, players generally know what to expect once they step onto the court.

But visiting locker rooms remain one of the great variables with divergent setups across the league. Size, furnishings, urinal access — it all depends on the city. Players and coaches have their favorites, which tend to be in newer arenas like Barclays Center, where the Nets play their home games and where the league had requirements in place.

So there is optimism among opposing teams about what awaits them at Golden 1 Center, the Kings’ new arena, which is scheduled to open in October. On a recent tour of the Golden 1 Center construction site, a team official pointed out the framework for the new visiting locker room, which will be rich in amenities — and pretty much the opposite of the visiting locker room at the kitschy old arena.

“You just want space,” said Garrett Temple, a guard with the Wizards. “I have a little exercise routine that I do to get my body loose. In bigger locker rooms, you usually have a little more room to do that. In smaller locker rooms, you have to avoid rolling over someone’s foot.”
