The Cross Bath

The one thing

The Cross Bath hands over an entire Georgian thermal bath, built on the site of a spring the Romans and the Celts both revered, for the sole use of one small group. Up to ten people, and no one else, floating in naturally warm spring water under open sky inside a building that has stood on this exact spot for two hundred and forty years.

The verdict

Bath sits on three hot springs, and while most visitors know the grand Roman Baths or the rooftop pool at the main Thermae spa, the Cross Bath is the small, quiet one, a single oval pool inside a Grade I listed Georgian building on Bath Street, fed directly by the Cross Spring itself. It has none of the scale of its neighbours, and that is rather the point. Where the main spa moves large numbers of people through a full circuit of pools and steam rooms, the Cross Bath offers exactly one thing, done completely, water drawn straight from the spring, inside a small and genuinely historic room, given over entirely to whoever has booked it.

For most of the week that means exclusive use, the whole building closed to everyone else, booked for up to ten guests at a time and built around a short, intense window rather than a long day out. The package folds in Champagne or juice and a spread of savoury treats, brought to the water's edge, and a poolside fountain adds its own quiet sound to a space that already feels a world away from the street outside. On Tuesdays the Cross Bath opens differently, in shared sessions that individual bookers can join without gathering a group, so the building earns its keep both ways, generous with strangers once a week and given over entirely to one party the rest of the time.

There is nothing else on site beyond the water itself. No treatment rooms, no sauna, no steam room, the operator says plainly that treatments are not part of a Cross Bath booking, and the wider Thermae Bath Spa handles all of that at its separate main building nearby. What the Cross Bath sells instead is something rarer, sole use of a genuinely old thermal bath, still filled from the spring it was built to hold, with none of the modern spa architecture layered on top.

Access is sensibly guarded. Under twelves are not admitted at all, and twelve to fifteen year olds only with an adult right beside them throughout, so this reads as an experience for adults, small groups of friends, a hen party, a quiet celebration, rather than a family outing. Guests bring their own swimwear, and towels and robes are provided along with the drinks and food included in the package.

The water

A single pool carries the entire experience, oval, open to the sky within the walled Georgian structure, and filled directly by the Cross Spring, one of Bath's three natural hot springs, with only the smallest amount of chlorine added to meet public bathing health and safety rules. There is no sauna, steam room or wider circuit at this building, the whole point is the one pool, given either to a private group of up to ten or shared on Tuesdays among individual bookers, with a poolside fountain and the sound of water against two centuries of stone doing the rest of the work.

Treatments

The Cross Bath does not offer treatments on site, the operator is clear about that, and anyone wanting a facial or a massage alongside their soak should look to the main Thermae Bath Spa building nearby, which handles the fuller treatment and thermal circuit under the same group. What the Cross Bath sells instead is the water itself, and the exclusive hire package includes Champagne or juice and a selection of savoury treats brought to you at the poolside, so the experience is built around the setting and the drink in hand rather than a treatment menu.

Getting in

Exclusive use of the whole Cross Bath is bookable most days of the week, at slots of noon, two and four in the afternoon, for up to ten guests at a time, and it is worth calling ahead since this is a phone and reception booking rather than the main site's online system. Shared sessions run on Tuesdays only, across five slots through the day, and individual bookers can join one of those without needing to fill the building themselves, with a discount available to Bath and North East Somerset residents. Under twelves are not admitted, and twelve to fifteen year olds need an adult with them throughout, so this suits an adult party rather than a family visit. The building is reasonably accessible, with lift and ramp access, accessible changing and toilet facilities, and assisted pool access chairs available on request.

What to know before you fall in love

There is one pool and nothing else, no sauna, steam room or treatment rooms on site, so this suits a short, focused soak rather than a full spa circuit, and anyone wanting treatments as well should plan a visit to the main Thermae Bath Spa building too.

Shared, individually bookable sessions run on Tuesdays only, so a solo visit or a pair without a wider group to gather needs to work around that single day, or book exclusive use of the whole building instead.

Under twelves are not admitted at all, and twelve to fifteen year olds only with an adult right beside them, so it is not a family day out.

Changing space is compact, built for a small private group rather than a crowd, which suits the intimacy of the format but is worth knowing before a larger party arrives.

Best for

Small private groups of up to ten wanting a short, genuinely historic thermal bathing experience with the whole building to themselves, hen parties, quiet celebrations and reunions especially, rather than a full day of treatments and circuits. Also well suited to a solo or paired visit on a Tuesday, sharing the same spring fed water without needing to book the whole space.
