The sun has dropped behind the fence, the air has that familiar early-evening coolness, and nobody is quite ready to go inside. It is the kind of moment a gas fire pit was made for: instant warmth, no smoke, no fuss, just a flame that keeps the evening going.
This year, the range at Ruma spans everything from compact standalone pits for courtyard spaces to premium fire pit tables and dramatic freestanding fireplaces. Five models stand out for their design, build quality and versatility.
Here is a closer look at each one, along with everything you need to make the right choice for your garden.
What to Consider Before You Choose
How Much Heat Do You Need
In an outdoor setting, where warmth disperses freely, a higher output matters. Most Cosi models run on a standard 5kg propane canister and produce a consistent, adjustable flame. The Cosivista 160 goes a step further, accepting a larger 10kg canister for extended run time and greater coverage.
As a rough guide, a fire pit producing around 6kW (approximately 20,000 British Thermal Units (BTU)) keeps four to six people comfortable. Models at 9kW and above work better for larger outdoor spaces or cooler evenings when you want to feel the warmth from further away.
Standalone Pit or Fire Pit Table?
A standalone gas fire pit is designed purely for atmosphere and warmth. A fire pit table adds a functional surface around the burner, which can be covered with a plate when the fire is off to act like a normal table surface. If your outdoor space serves multiple purposes across the day and evening, a fire pit table might be the better option.
Safety and Ignition
Every Cosi model available at Ruma uses battery-powered electronic ignition: one press, and the flame is lit. No matches, no fuss. Glass surrounds are sold separately for most models and are strongly recommended if children or pets use the garden. The enclosed flame they create is safer, whilst keeping the presentation visually refined.
The 5 Best Gas Fire Pits at Ruma
1. Cosibrixx Anthracite Fire Pit — The Compact Choice
60x60x63 | 5kg propane
For a smaller garden, a tucked-away patio, or simply a space where the fire needs to fit in rather than take over, the Cosibrixx Anthracite Fire Pit delivers everything that matters. It is compact at 60cm square and low at 35cm, but that simplicity is part of its appeal: slide it into a seating arrangement, add the glass surround, and it becomes a quietly brilliant focal point without demanding a lot of the space around it.
The powder-coated anthracite finish is clean and durable. Lava rocks, ceramic logs and a top plate are all included, and it runs off a standard 5kg propane canister. This is the model to choose if you want the warmth and atmosphere of a gas fire without the footprint of a full fire table.
Best for: Smaller patios, courtyards and balconies. A considered first fire pit with a clean, compact profile.
2. Cosicube 70 Grey Wash Fire Pit — The Natural Statement
70x70x58cm | 5kg propane
The Cosicube 70 Grey Wash Fire Pit looks like it belongs to a different family entirely from the sleek metal models. Its fir wood exterior, finished in a soft grey wash, brings warmth and natural texture to the picture. A stainless steel top completes the look: modern where it needs to be, characterful everywhere else.
At 70cm square and 58cm high, it stands taller than the Cosibrixx and makes for a more prominent centrepiece. It is still a standalone fire pit rather than a table, and that suits a garden that already has good outdoor furniture and is looking for something to anchor the space atmospherically rather than functionally. Battery-powered electronic ignition, lava rocks, ceramic logs and a top plate are all included.
Best for: Gardens with a natural, Scandi or coastal feel. Anyone who wants a taller, more characterful standalone fire pit.
3. Cosiloft Sandy Beige Square Fire Pit Table — The Practical All-Rounder
100x100x50cm | 5kg propane | 6 Colourways
The Cosiloft Sandy Beige Square Fire Pit Table effortlessly blends stylish ambience with outdoor practicality. Featuring a sandy beige metal frame and a neutral stone-look top, it fits naturally into a lounging set as the perfect accent for a Scandi-inspired garden.
It offers ample space for al-fresco dining or summer cocktails. Come evening, the included ceramic logs and lava stones take centre stage, powered by a 5kg gas canister stored neatly out of sight. You can enhance the table further by adding the matching glass surround and metal cover plate to protect the burner when not in use.
Best for: Outdoor lounging sets. Anyone who wants fire pit function and coffee table practicality in one piece of furniture.
4. Cosipure 100 Black and Teak Square Fire Pit — The Premium Entertainer
100x100x51cm | 5kg propane
There is a reason the black and teak combination has become one of the most-loved finishes in outdoor design: it is timeless, warm and works in almost any garden setting. The Cosipure 100 Black and Teak Square Fire Pit brings that combination to a fire pit table that feels genuinely elevated.
The teak surface wraps around the central burner on all four sides, giving everyone around the table a natural, warm surface for their drinks. The cover plate means the burner disappears when not in use, leaving a beautiful coffee table behind. Lava rocks and ceramic logs are included, and the fire runs on a 5kg propane canister. As for the teak, leave it to silver naturally outdoors, or treat it occasionally to hold the honey tone.
Best for: Garden entertaining spaces and premium outdoor schemes. Pairs naturally with black-framed outdoor furniture.
5. Cosibridge Teak and Black Rectangle Fire Pit Table — The Garden Statement
140x80x50cm | 5kg propane
Nothing else in the Ruma fire pit range combines al-fresco dining and luxurious warmth quite like the Cosibridge Teak and Black Rectangle Fire Pit Table. Designed with a sleek black metal base and a stunning slatted teak wood tabletop, it exudes a minimalist, Scandi aesthetic that will perfectly complement any modern garden space.
This fire pit dining table is incredibly versatile, offering ample space for hosting dinner parties or enjoying a few cocktails late into the summer night. It accommodates a standard 5kg gas canister which can be easily sourced from your local gas retailer, keeping the atmospheric flames burning while you entertain. Ceramic logs and lava stones are included to complete the look, and you can enhance your setup further by protecting the flames with the matching glass surround and metal cover plate.
Teak Maintenance: The natural teak top will age beautifully when left to the elements. You can leave it outside, store it indoors, or use a weather protection cover. If you do use a cover, simply remove it every so often to allow the wood to breathe.
Best for: Large gardens and generous terraces. A focal point that redefines a space rather than simply warming it.

Standalone Pit or Fire Pit Table: How to Decide
If your outdoor space already has good furniture and you want to add warmth and atmosphere without changing the layout, a standalone pit like the Cosibrixx or Cosicube fits in beautifully. Compact, unfussy and purely focused on the fire experience.
If your outdoor space is an extension of how you actually live, a place for morning coffee, afternoon sun and evening drinks, a fire pit table like the Cosiflow or Cosipure does more across the day. That versatility is what makes fire pit tables the more popular choice for outdoor entertaining.
Frequently Asked Questions About Gas Fire Pits
Are gas fire pits safe to use in a UK garden?
Yes. Gas fire pits running on propane LPG are legal and safe to use in UK gardens. Propane is a clean-burning fuel that produces no smoke, making it compliant in Smoke Control Areas where wood burning is restricted. Position the fire pit at least 3 metres from fences, structures and overhead foliage, and avoid using one under a parasol or pergola.
How long does a 5kg gas canister last?
On a moderate setting, a 5kg propane canister typically gives eight to twelve hours of use. The Cosivista 160 can take a 10kg canister, roughly doubling that run time, which makes a meaningful difference for regular garden entertaining or cooler evenings when the fire runs at a higher setting.
Are glass surrounds included with Cosi fire pits?
Glass surrounds are sold as optional accessories rather than included as standard across the Cosi range. They are well worth adding: the enclosed flame is safer for children and pets whilst remaining visually refined. Browse the full range of fire pit accessories to find the right fit for your model.
