What’s inside?

Step inside 93 Shernhall Street, exhale and find your own pace between hot and cold.
Two saunas. Two plunges. One hour to relax into it.

  • Two large traditional Finnish saunas. No steam, just dry heat the way it's meant to be.

    One is social: chat with friends, meet strangers, let the conversation go wherever it goes.

    One is silent: no talking, just the heat and whatever's on your mind. Some sessions you just need the quiet.

    Pick your mood. Or try both. Each sauna seats up to 12 people.

  • Two ice baths, two temperatures.

    The 9°c is the one most people start with. It’s cold enough to feel it but manageable enough to actually get in.

    The 5°c is for when you're ready to go deeper.

    A third bath is on the way. It will go down to 2°c for the brave ones.

    The transition from hot to cold is where the magic happens but there is no pressure to step into a plunge at all.

  • We're finishing it now. The studio will be home to extended contrast therapy sessions, breathwork, yoga, and small group workshops.
    It’s a beautiful, light space designed for the slower, deeper side of what arvo is about.

Our story

London doesn’t pause for you.

So we built a space that does.

Arvo sauna is simple. We want to create a warm, inviting space that leaves you feeling lighter than when you arrived.

No notifications. No pressure. No crowds.
Just warmth, water, and social connection.

It started with our own experiences. Hot and cold therapy helped us recover, unwind, and feel more at ease in the middle of the chaos of city living. Now we’re sharing our space with you.

Come and soak it up - chat, connect, relax.

We can’t wait to meet you!
