They may be no-frills, but the bathrooms at Ball Arena are clean and, most important, abundant. With a capacity of 20,000, it's essential that the venue — which brings in national touring acts such as Billie Eilish and John Mayer and hosts basketball and hockey games and monster truck rallies — have enough bathrooms, because there's nothing worse than waiting in line for 45 minutes and missing your favorite song. Fortunately, Ball Arena has plenty of them — and they're conveniently located next to other services such as food and drink stations.
