Termas Outdoor Spa sits on the roof of Casa Bonay, a short walk from Plaça Catalunya, built as an open-air circuit inspired by Nordic sauna culture. The layout mixes a dry sauna, hammam, ice bath and Japanese ofuro around greenery and open sky, with the whole space designed by Andreu Carulla alongside landscaper Fernando Martos.

Most visits run as one of three guided circuits — Relajante, Détox or Revitalizante — in 50-minute sessions capped at six people, with the option to book the entire rooftop privately for a group. Visitors who don't want a structured circuit can instead use the facilities freely at their own pace.

Two treatment cabins round out the offer, with facials and massage styles drawing on shiatsu, ayurveda and acupuncture-inspired techniques, plus lymphatic drainage and a neuro-sedante massage. A treatment menu is available as a downloadable PDF on the official site.

Opening hours shift through the week: closed Monday, 13:00–20:00 Tuesday through Thursday, 10:00–20:00 Friday, and 10:00–18:00 on weekends. Reservation is required, and the venue falls in the upscale price tier, so it's worth booking a circuit slot or treatment ahead rather than showing up unannounced.

Good to know

Do I need to book ahead?
Yes, reservation is required — you can book circuits or treatments through the official site or by calling the spa directly.
What's included in a circuit session?
Each circuit (Relajante, Détox or Revitalizante) runs 50 minutes for groups of up to six, cycling through the dry sauna, hammam, ice bath and Japanese ofuro; you can also privatize the whole space for your group.
Can I just use the facilities without a set circuit?
Yes, there's an option for free use of the space at your own pace instead of following one of the structured circuits.
What hours is it open?
It's closed Monday, open 13:00–20:00 Tuesday to Thursday, 10:00–20:00 Friday, and 10:00–18:00 on Saturday and Sunday.
Are massages available separately from the sauna circuit?
Yes, there are two treatment cabins offering facials and massages including shiatsu, ayurveda-inspired work, lymphatic drainage and a neuro-sedante massage; check the downloadable menu for specifics.
