About

The middle ground within the Frodo depth range.

Neither the most compact nor the most generous Frodo option. The straightforward choice for typical garden layouts that do not need a shallower or deeper variant specifically. This is the Single XL Room configuration.

Choosing the standard depth within a range of variants, rather than the most compact or most spacious option, often reflects a sensible, considered approach to matching a sauna purchase to genuinely typical needs rather than either extreme. The core physiological benefits of sauna bathing, improved circulation, reduced muscle tension, a cardiovascular effect comparable to light exercise, apply equally regardless of which specific depth variant a household chooses.

For most households, this standard depth balances comfortable group capacity for five or six people against a footprint that fits typical garden layouts without requiring exceptional space. That balance tends to suit the realistic usage patterns and available space of the majority of UK households considering an oval sauna, making it a genuinely practical default rather than a compromise.

The distinctive porthole door and round window design carries through at this standard depth, ensuring households don't sacrifice any of the Frodo series' particular visual character by choosing the middle option rather than a more extreme depth variant. Group sauna sessions at this size bring genuine social and mood benefits, with the relaxed, unhurried sauna environment naturally encouraging conversation in a way that's central to the format's appeal across many sauna cultures.
Delivered flat-packed for self-assembly, with free UK mainland delivery on qualifying orders. The larger Cube format requires a little more assembly time than the smaller Icon models, so we recommend allowing a weekend and having a second person to help. A solid, level base and suitable delivery access are required.

For a complete setup, select Professional Installation and choose your preferred date, allowing for the stated production lead time. We’ll then arrange the installation around your requirements, including any additional preparation or works needed to accommodate your sauna where possible.

Electric sauna heaters require a suitable dedicated electrical supply and are not simply plug-and-play. The power requirements depend on the heater's output and the electrical supply available at the property.

Smaller heaters may be suitable for a 230V single-phase supply, while larger or more powerful heaters can require a 400V three-phase supply. Single-phase power uses one electrical phase, whereas three-phase power distributes the load across three phases and is better suited to higher-powered equipment.

The correct supply will depend on the specific heater you choose, so the heater's electrical requirements should always be checked before installation.

Sauna heaters will normally need to be hard-wired into a correctly rated dedicated circuit with the appropriate cable, isolation and electrical protection. They should not be connected using a standard household plug or extension lead.

The final electrical connection should be completed by a suitably qualified electrician in accordance with the heater manufacturer's instructions and applicable electrical regulations. This is important for both safety and reliable operation of the heater.

If you're based in the Leicestershire area, we can arrange the electrical installation of your sauna heater for an additional fee. Please speak to our team if you'd like this included with your sauna.

Wood-fired sauna heaters do not require an electrical supply for heating, but they do require the correct installation of the stove, chimney, flue and surrounding heat protection.

The stove must be positioned according to the manufacturer's required safety distances from timber walls, benches and other combustible materials. Depending on the stove and sauna design, suitable heat shields or other non-combustible protection may also be required.

The floor beneath and immediately around the stove may also require suitable non-combustible protection, particularly where there is a risk of embers or hot material falling from the stove.

A suitable chimney and flue system must be installed to safely carry smoke and combustion gases outside the sauna. Where the flue passes through the roof, the correct insulated chimney components, roof flashing and heat-resistant protection should be used.

Correct ventilation is also important. A wood-fired stove requires an adequate supply of combustion air, while the sauna itself needs sufficient airflow to provide fresh air, circulate heat and allow moisture to escape.

When choosing the position of an outdoor wood-fired sauna, you should also consider where the chimney will discharge in relation to your house, neighbouring properties, windows, boundaries and outdoor seating areas.

Any applicable local requirements should be checked before installation, particularly where chimney positioning, smoke control or other restrictions may apply.

The Frodo 240 needs standard oval sauna care, with attention to its distinctive glass door and round window given their role in the porthole design. After every session, leave the door open for twenty to thirty minutes to let the heat room dry out fully, preventing mould and dark staining on timber surfaces. Wipe benches down once cooled, and sand the interior lightly once or twice a year wherever group use creates the most contact wear.

The glass door and round window need regular cleaning with a standard glass cleaner and soft cloth, given their combined role as this model's signature visual feature.

Externally, treat the curved Thermowood exterior with a wood treatment every two to three years depending on weather exposure. Keep the base clear of debris and standing water along the full footprint, the same fundamental care any outdoor timber sauna needs regardless of specific depth within the Frodo range.
This sauna comes with a 5 year warranty for residential use and 2 years for commercial use, covering structural timber, glazing, and hardware. Valid claims are assessed case by case, and we'll supply replacement parts wherever possible rather than the whole sauna.
Production takes 10-12 weeks, plus 1-2 weeks dispatch time for pallet haulage. This sauna is delivered flat packed unless otherwise stated. Free UK mainland shipping applies to orders over £500 covering up to one double pallet (2.4m x 1.2m x 2.2m) or two single pallets (1.2m x 1.2m x 2.2m). Given this model's size and weight, additional pallet charges may apply and will be quoted separately based on your postcode, and forklift unloading may be required as it exceeds normal tail-lift limits (1000kg). Please have a solid base, clear access, and suitable unloading space ready before delivery, with help on site if needed. Pallet deliveries are kerbside only, and you're responsible for moving goods onto your property.

Wood-Fired Heater Setup

Wood-fired sauna heaters do not require an electrical supply for heating, but they do require the correct installation of the stove, chimney, flue and surrounding heat protection.

The stove must be positioned according to the manufacturer's required safety distances from timber walls, benches and other combustible materials. Depending on the stove and sauna design, suitable heat shields or other non-combustible protection may also be required.

The floor beneath and immediately around the stove may also require suitable non-combustible protection, particularly where there is a risk of embers or hot material falling from the stove.

A suitable chimney and flue system must be installed to safely carry smoke and combustion gases outside the sauna. Where the flue passes through the roof, the correct insulated chimney components, roof flashing and heat-resistant protection should be used.

Correct ventilation is also important. A wood-fired stove requires an adequate supply of combustion air, while the sauna itself needs sufficient airflow to provide fresh air, circulate heat and allow moisture to escape.

When choosing the position of an outdoor wood-fired sauna, you should also consider where the chimney will discharge in relation to your house, neighbouring properties, windows, boundaries and outdoor seating areas.

Any applicable local requirements should be checked before installation, particularly where chimney positioning, smoke control or other restrictions may apply.

Oval Sauna Frodo 240 XL Room — Glass Door & Round Window Thermowood — thermowood — angle view 1

The sensible default depth for most gardens

Oval Sauna Frodo 240 — Single XL Room — Glass Door and Round Window — Thermowood matches the standard oval sauna depth at 240 centimetres alongside the consistent 400 centimetre width and 248 centimetre height found across the Frodo series, solid Thermowood construction delivering the same genuine thermal performance expected throughout the oval range. This depth sits in the middle of the available Frodo variants, neither the most compact nor the most generous option.

As the standard depth within the Frodo naming convention, this version gives buyers a clear reference point against which the shallower 195 and deeper 300 and 500 variants can be measured, each adjusting depth alone while keeping width and height consistent throughout. Solid timber construction ensures reliable performance across every UK season regardless of which specific depth a buyer ultimately selects.

Oval Sauna Frodo 240 — Single XL Room — Glass Door and Round Window — Thermowood suits anyone wanting the standard, well balanced oval sauna depth without needing to consider whether a shallower or deeper variant might suit their garden better, the kind of straightforward middle option that suits the majority of typical garden layouts. It tends to be the depth most buyers settle on once they have measured their available space honestly, finding it strikes the right balance between interior room and overall garden footprint without requiring any special consideration either way. This is the Single XL Room configuration.
