Bournville Lane Baths were unusual in that they featured an aeration and filtration system for the water which was extracted from a mains supply. This meant that the baths did not need to be emptied and refilled. This system was modern and the system was later installed in all swimming baths controlled by local authorities meaning that King's Norton and Northfield District Council were the first local authority in the country to use such a system. The Baths were built in 1910 to a design by John P. Osborne. The building is Grade II listed.
