Basel / Basel-Land indoor swimming

Does anyone know of good indoor swimming facilities in the BS/BL area?

I like an early morning swim but most of the venues I see on Google have some odd opening hours (such as, opening after lunchtime only). Even if the facility is not a dedicated Hallenbad, somewhere like a fitness club (like a David Lloyd club back in the UK, for example) with a decent pool as part of their facilities would be good. Feeling a tad underwhelmed by the indoor swimming options, unless some great clubs are tucked away somewhere I just don't know about yet.

Thanks all!

Heard good things about Eglisee. Never been there myself. https://www.jfs.bs.ch/fuer-sportleri...d-eglisee.html

Laguna has a 50m pool as well.

Here's a list:
