The Centre Sportif
This is certainly not the most luxurious of spas in Verbier but it is clean, open to the general public and is equipped with saunas, steam rooms and jacuzzi. You will have to pay a little extra for the sauna and steam rooms but access to the large jacuzzi is free with a swimming ticket.
If you manage to get it to yourself it is wonderful but it can be a bit squashed if eight people squeeze in. However it is often full of loud teenagers so we can’t guarantee it. Go early afternoon is our best advice.
