I believe both are full co-ed besides the bathroom areas. Have been to both with my wife and never was told I couldnt go somewhere with her besides the ladies change/bath area.

In coed regards I think they are the same, I've only been to king spa though. I would assume Sojo is bigger and also has the outside pools.

Sojo.

Both other commenters are correct; both spas have large coed sections and single-sex changing/bath areas. But in addition to these, Sojo has coed outdoor pools and tubs.

If you’re looking for coed options, stay clear of Island spa in Edison. It’s very much single sex and they insist you’re naked

As a fan of both, I would recommend Sojo for a first time visit. It's a larger facility with more areas to go to together.

For the bath area only, which is optional. The sauna section is very much co-ed and clothed. Spa King in Pal Park is the same.

Good to know!!! Thank you’

Sure! I wouldn't want anyone to miss out since it's a fun time.

Aire in Manhattan is exceptional. Also look into Mirabeau in Skaneateles NY for a special get away.
