The Engine Rooms At Birchwood Park
101 Faraday St, Warrington, Cheshire
100% positive
Directions: Gender neutral facilities are near the north entrance, 3x individual enclosed cubicle rooms. Gender-segregated facilities are available in the cafeteria area near the south entrance by the lake - these include wudu ablution facilities. A unisex accessible facility is also available in the lobby area near the south entrance.
Comments: The Engine Rooms is a restaurant and cafe plus conference centre with lots of comings and goings during the day. I don't know if they technically have a policy on facilities being for guests, but you should be fine to walk straight in
