Downtown Seattle is the urban core of the city and the most visited area by tourists, commuters, and locals alike. From the iconic Pike Place Market to the Seattle Central Library, Westlake Center, and Pacific Place Mall, downtown offers an enormous amount to see and do. Fortunately it also has the highest concentration of public restrooms in the entire city, making it one of the easier areas to navigate when nature calls. Westlake Park in the heart of downtown has free public restroom facilities that are centrally located and easy to find. The park sits at the intersection of 4th Ave and Pine Street and is a major transit hub, making it a convenient stop whether you're arriving by bus, light rail, or on foot. Pacific Place Mall on 6th Ave has some of the cleanest public restrooms in downtown Seattle, located on the fourth floor. The mall is open daily and the restrooms are well-maintained throughout the day. Westlake Center on 4th Ave also has customer restrooms available during mall hours. The Seattle Central Library at 1000 4th Ave is open to the public and has accessible, clean restrooms on multiple floors. The library is free to enter and is one of the most architecturally stunning buildings in the city, so it's worth a visit on its own merits. Hotel lobbies are another reliable option in downtown Seattle. The Hyatt Regency, Sheraton Grand, and Westin Seattle all have lobby-level restrooms that are generally accessible to non-guests, particularly during daytime hours. This is a common strategy among experienced Seattle visitors. Pike Place Market has public restrooms in the main market building, accessible during market hours. The restrooms are located on the lower level and can have lines during peak tourist season in summer. The waterfront area just below the market also has public facilities along the new Waterfront Park promenade.
