Sauna with bi-fold doors UK
A sauna with bi-fold doors transforms any installation into an architectural statement, folding away entirely to merge the cabin with its surroundings and flood the interior with light. Gravity Wellness, trading as York House Group (Company No. 15903905), handcrafts every bespoke sauna bi-fold doors design to order in sustainably sourced Canadian hemlock, delivering free to mainland England, Scotland and Wales.
Why a sauna with bi-fold doors UK buyers are choosing right now
Interest in a sauna with bi-fold doors UK has grown sharply as more homeowners invest in premium wellness spaces at home. Unlike a standard hinged door, a full-width bi-fold panel collapses to one side in a single fluid motion, opening the entire front face of the cabin. That unobstructed aperture is particularly desirable for outdoor installations, where the sauna can face a garden, terrace or courtyard and allow bathers to step straight from the heated interior into the fresh air without ducking or turning sideways. Gravity Wellness builds each custom sauna UK to a bespoke specification, meaning the door panel count, glazing style and frame finish are all agreed with you before a single piece of timber is cut. Explore the full range on our sauna collection page.
Canadian hemlock, the timber at the heart of every Gravity Wellness build, is naturally antimicrobial and PEFC certified for sustainable forestry. Its tight, even grain means it accepts heat gradually and releases it slowly, keeping surface temperatures comfortable to touch even when the cabin reaches 90 degrees Celsius. York House Group, registered at Meadow House, Long Bennington Business Park, Newark, NG23 5JR, is a UK-registered business and every sauna is built to comply with UK electrical standards, running from a standard 13-amp socket at a maximum of 2000W.

The features that define a bespoke sauna bi-fold doors build from Gravity Wellness
Every bespoke sauna bi-fold doors configuration starts with a consultation to establish how many panels you need, whether you prefer full-height tempered safety glass or a part-glazed timber-infill panel, and which direction the doors should stack. Standard bi-fold hardware operates on an overhead aluminium track with floor-mounted pivot pins, and Gravity Wellness sources only commercial-grade stainless steel fittings rated for the high-humidity environment inside a sauna cabin. The doors themselves are constructed from the same PEFC-certified Canadian hemlock as the walls, ensuring a consistent thermal performance and a visually seamless appearance. Internal dimensions are agreed at the design stage, so the finished aperture can span anywhere from 900mm for a compact single-person cabin up to 1800mm or wider for a family-sized outdoor room. Our four-person traditional sauna is a popular starting point for buyers wanting a full-width bi-fold front.
For UK buyers considering a custom sauna UK installation outdoors, the bi-fold door design offers a significant practical advantage: when fully open, there is no protruding door panel to obstruct circulation around the cabin. This matters especially on smaller urban terraces where every centimetre of clearance is valuable. All Gravity Wellness saunas are wired for a maximum of 2000W, meaning no dedicated electrical circuit is required — the heater plugs into any standard 13-amp socket, which considerably simplifies the installation process for most UK properties. Explore our two-person traditional sauna to see how a bi-fold door scales to a mid-sized cabin.
Tempered safety glass panels
Each glazed panel uses 8mm tempered safety glass that withstands sustained temperatures above 120 degrees Celsius and shatters into blunt fragments rather than sharp shards, meeting UK building safety expectations for enclosed heated spaces used by families.
Commercial-grade stainless hardware
Grade 316 stainless steel hinges, pivot pins and overhead track are specified as standard on every bi-fold door build, providing corrosion resistance in environments that regularly reach 90 percent relative humidity and surface temperatures above 80 degrees Celsius.
Integrated digital control panel
A flush-mounted digital controller is recessed into the interior wall at bench height, allowing temperature and timer settings to be adjusted without leaving your seat. The panel is pre-wired at the factory and connects to the 2000W heater via a single standard UK plug.
Why choose Gravity Wellness for your sauna with bi-fold doors UK
Gravity Wellness is the trading name of York House Group, Company No. 15903905, registered at Meadow House, Long Bennington Business Park, Newark, NG23 5JR — a fully UK-registered business with transparent company credentials that you can verify at Companies House. Every sauna with bi-fold doors UK order is built entirely by hand from PEFC-certified Canadian hemlock, a timber chosen for its natural antimicrobial properties, dimensional stability in high-humidity conditions and warm honey tone that deepens beautifully over years of use. Because each cabin is made to order rather than pulled from warehouse stock, there is no compromise on dimensions, door configuration or finish — your specification is the specification. The approximately 60-day build and delivery window exists because skilled craftspeople construct your cabin from scratch, not because of logistics delays. Delivery is included in the price to any address on mainland England, Scotland and Wales. Discover our one-person traditional sauna as a compact bi-fold starting point.
The ordering process is straightforward. You contact the team at health@gravitywellness.co.uk with your preferred dimensions, door panel count and any specific requirements. Gravity Wellness will confirm the specification, provide a written quotation and agree a build start date. From that point, the approximately 60-day clock begins, covering timber preparation, frame construction, door fitting, heater installation and quality inspection before the cabin is carefully packaged and dispatched. Updates are provided throughout the build. For those considering an infrared alternative to a traditional Finnish heater, our infrared one-person sauna is also available with a bespoke bi-fold door upgrade.
Every sauna with bi-fold doors UK that leaves the Gravity Wellness workshop is a wholly handmade structure built to your exact measurements by York House Group (Company No. 15903905), using sustainably sourced Canadian hemlock and delivered free to your door on mainland Great Britain.
Planning your installation: space, electrics and ventilation for a sauna with bi-fold doors UK
Before ordering your custom sauna UK, three practical considerations need addressing: floor space, electrical supply and ventilation. For floor space, allow the full external footprint of the cabin plus a minimum of 600mm clearance on the bi-fold door side to permit the panels to stack and swing clear. A typical two-person bi-fold cabin measures approximately 1200mm deep by 1800mm wide externally, so you should plan for a total area of at least 1200mm by 2400mm including door travel. On level, load-bearing surfaces — concrete, paving or decking rated to at least 250kg per square metre — no additional base preparation is usually required. Electrical supply is straightforward: because Gravity Wellness heaters run at a maximum of 2000W, a standard 13-amp socket within 2 metres of the cabin is sufficient. No electrician is needed to install a dedicated circuit, which removes a common barrier for homeowners. Ventilation is achieved through a low-level inlet vent and a high-level adjustable exhaust vent, both pre-fitted at the factory, so fresh air circulation meets the requirements for safe sauna use without any additional building work.
For outdoor installations, Gravity Wellness recommends positioning the bi-fold door face away from the prevailing wind direction — typically the south-west in most of mainland England, Scotland and Wales — so that opening the doors mid-session does not create a sudden cold draught. A short gravel or paved path between the sauna and the house improves the all-weather experience considerably. If you are planning an indoor installation in a garage conversion or garden room, ensure the floor drain or absorbent mat can handle condensation from the open door panel. The team at health@gravitywellness.co.uk is happy to advise on any site-specific queries before you commit to a specification. You can also browse all outdoor sauna options to compare configurations.

How long does delivery take for the sauna with bi-fold doors UK to mainland UK?
Because every sauna with bi-fold doors UK is built entirely to order, the lead time is approximately 60 days from the point your specification is confirmed and the build is scheduled. This window covers the full handcrafting process — timber preparation, frame and door construction, heater fitting and a pre-dispatch quality inspection — followed by delivery to your mainland England, Scotland or Wales address. No sauna is held in warehouse stock. Gravity Wellness will keep you informed throughout the build period and confirm your delivery date in advance.
What timber is used to build the sauna with bi-fold doors UK?
Gravity Wellness uses PEFC-certified Canadian hemlock throughout every sauna with bi-fold doors UK build, including the structural frame, wall cladding, benching and door frames. Canadian hemlock is selected for three principal reasons: it is naturally antimicrobial, which means it resists mould and bacteria without chemical treatment; it has a low resin content, so it remains comfortable to sit against even at temperatures approaching 90 degrees Celsius; and its tight, consistent grain provides excellent dimensional stability in the high-humidity conditions inside a working sauna cabin. The timber is sustainably sourced and its PEFC certification can be provided on request.
Does the sauna with bi-fold doors UK require professional installation?
In most cases, professional installation is not required. The sauna with bi-fold doors UK is delivered as a fully assembled or panel-kit cabin that two adults can position and connect in a single afternoon using standard hand tools. The heater operates at a maximum of 2000W and connects to any standard 13-amp socket, so no electrician is needed to install a dedicated circuit unless you prefer one for cable management reasons. You will need a level, load-bearing surface to place the cabin on and a 13-amp socket within approximately 2 metres. The team at health@gravitywellness.co.uk can advise on any site-specific queries before purchase.
What size space do I need for the sauna with bi-fold doors UK?
Because Gravity Wellness builds each sauna with bi-fold doors UK to a bespoke specification, the external footprint is agreed at the design stage rather than fixed in advance. As a practical guide, a two-person cabin typically measures approximately 1200mm deep by 1800mm wide externally. You should add a minimum of 600mm to the width on the door-opening side to allow the bi-fold panels to stack and swing clear without obstruction. The floor surface must be level and capable of bearing at least 250kg per square metre. Indoor installations should have a ceiling height of at least 2200mm to accommodate comfortable bench use and adequate hot-air circulation.
What warranty covers the sauna with bi-fold doors UK from Gravity Wellness?
Gravity Wellness stands behind every sauna with bi-fold doors UK with a manufacturer warranty covering structural timber components, the bi-fold door hardware and the electrical heater and control panel.
