Baths in Fellbach, Swimming center in Fellbach, Germany.

The F3 Familien- und Freizeitbad is a swimming center in Fellbach with multiple indoor and outdoor pools, diving boards, and water slides. The facility provides areas for recreational swimmers and features saunas and relaxation zones all under one large roof.

Designed by Stuttgart office 4a Architekten at a cost of about 43 million euros, the F3 was built from the first sod on 3 May 2011 and topped out on 28 February 2012. The indoor pool opened on 15 September 2013, replacing the old Hallenbad on Schillerstraße; the outdoor pool followed in summer 2014, replacing a nearly 60-year-old Freibad on Untertürkheimer Straße. The Städtische Holding Fellbach took over the operating company on 1 August 2020.

The pool hosts the Internationale Einladungsschwimmfest, an invitational swimming meet held annually by TSV Schmiden, and serves as a training venue for the swimming sections of SV Fellbach and TSV Schmiden. Gymnast Christina Tschernischew, a former member of the German national team, trained here. On the last day of the 2016 outdoor season the pool held its first dog-swimming day.

The bath stands on the western edge of Fellbach near the Kappelberg; the indoor pool and sauna area are open year-round, while the outdoor pool operates only in the summer half-year. The complex covers about 11,320 m², so allow time to move between the family pool, outdoor pool and sauna garden. It is run by the F3 Betriebsgesellschaft Kombibad Fellbach GmbH.

The Aqua Loop is an 88-metre looping slide with a rocket start, the only one of its kind in the Stuttgart region; Germany has only a few looping slides, and this is among the highest single loops. The slide tower also holds a 59-metre turbo slide and the 118-metre tyre slide Aqua Racer.
