Leil® Viva 120 1-2 Person Outdoor Sauna

Yes. The £3,999 complete kit includes the Harvia Vega Compact BC35 3.5kW electric heater and 12kg of sauna stones.

The BC35 has built-in controls, so it does not need a separate external controller. Final wiring must be completed by a qualified electrician; electrical connection is not included with sauna assembly.

Flat-pack delivery arrives on a large pallet at your driveway, so you will need to arrange assembly yourself or use our installation team. Fully assembled delivery (+£1,200) includes a forklift or crane to unload the sauna and place it in position.

Any separate installation work is priced according to your location and site. Use the Request an Installation Quote button above the options and complete the form for an exact price.

In most UK properties, a sauna of this size falls under permitted development and doesn't require planning permission. However, regulations vary for listed buildings, conservation areas, or if you're extending existing structures. We recommend checking with your local planning authority to confirm your specific circumstances.

The optional HUUM DROP 4.5kW heater requires a dedicated electrical supply installed by a qualified electrician. It needs a 32A circuit breaker and appropriate cabling to meet UK electrical regulations (BS 7671). We can provide detailed electrical specifications and recommend certified electricians in your area.

Professional installation typically takes 1-2 days depending on site access and preparation. This includes positioning the sauna, connecting electrical systems (if applicable), and final testing. DIY flat pack assembly can take longer depending on experience level. We provide comprehensive assembly instructions with all flat pack deliveries.

The Viva 120 requires a solid, level base capable of supporting 400kg. Options include a concrete pad, paving slabs, or a reinforced timber deck. The base should be slightly larger than the sauna footprint (at least 1.3m × 1.4m) and provide adequate drainage. We can advise on the best foundation solution for your site during the quotation process.

With the HUUM DROP 4.5kW heater, the Viva 120 typically reaches optimal sauna temperature (70-80°C) in 30-45 minutes. The compact 2.7m³ volume means faster heating compared to larger models. Using WiFi control, you can preheat your sauna remotely so it's ready when you arrive home.

Outdoor saunas are not maintenance-free. As a minimum, owners should be prepared to inspect and re-treat exposed timber at least every 12 months, or sooner if the manufacturer manual and local conditions require it.

You should also expect normal upkeep such as keeping the sauna clean and ventilated between uses, and making minor door or hinge adjustments over time in line with the manual.

In coastal or sea-air environments, exposed metal parts should be checked more regularly and protected with a rust-proof treatment such as WD-40 or another suitable anti-corrosion product.

Sauna heaters also require maintenance in line with the manufacturer manual. This normally includes periodically checking, washing, and restacking the stones, and in the longer term electric heater elements may need replacing if they wear out.

We do not currently offer a formal maintenance programme.

Absolutely! The Viva 120 is designed for year-round outdoor use. The insulated construction maintains heat efficiently even in cold weather, and the weather-resistant exterior timber is built to withstand British weather conditions. Many users find winter sauna sessions particularly invigorating.

All Leil saunas come with a 2-year manufacturer's warranty covering structural defects and workmanship. Electrical components (heater, controls) have separate manufacturer warranties. HUUM heaters come with their own 5-year warranty. We also provide ongoing support and can source replacement parts if needed in the future.

The Viva 120 features an EPDM (Ethylene Propylene Diene Monomer) roof – a durable synthetic rubber membrane widely used on flat and low-slope roofs. EPDM is known for exceptional waterproofing, UV and ozone resistance, flexibility in cold temperatures, and a long lifespan, making it ideal for year-round outdoor use in British weather conditions.

No. Our installation team can assemble the sauna, but the heater and any other electrical components must still be connected by a qualified electrician.

You will need a suitable electrical supply and, at minimum, an isolator switch. Full details are provided in the Electrical Supply section on the product page.

Yes. Any qualified electrician should be able to connect the sauna, provided they follow the electrical requirements listed in the Electrical Supply section of the product page.

After you place your order, we also send further information that you can pass on to your electrician.

In some cases, we may be able to share details of electricians who have connected saunas for previous customers.

Availability will depend on your location, and you are also welcome to use your own qualified electrician.

Assembly time depends on the model, access and site conditions. Many outdoor saunas can be assembled in around one day, while larger or more complex models may take longer.

Use the Request an Installation Quote button above the options and complete the form. We will confirm the expected installation time with your quote.

Yes. Our installation team uses specialist carpenters and installers who are experienced in assembling outdoor saunas, which is one of the reasons many customers prefer professional installation.

No. We do not carry out site visits.

To request an installation quote, use the Request an Installation Quote button above the options and complete the form with photos, measurements, site plans, access details and the proposed sauna location. Our installation team will use that information to assess access, base preparation and positioning, and flag any obvious issues before installation.

In outdoor saunas, it is normal for the timber structure to respond to changes in temperature, humidity, and ambient conditions over time. This can occasionally cause minor movement in the door opening, which may affect how the door closes or sits within the frame.

For this reason, sauna door hinges are designed to be adjustable. Minor door or hinge alignment adjustments over time are normal and should be carried out in line with the manual as part of routine ownership maintenance, rather than being treated as a product fault.

We do not currently have a full showroom, but many of our existing customers are happy to show their sauna to prospective buyers.

If you would like to see one in person, please contact us and we can try to arrange a viewing with a customer in or near your area.

Yes. Outdoor saunas are not maintenance-free.

As a minimum, owners should expect to inspect and re-treat exposed timber at least every 12 months, or sooner if the manufacturer manual and local conditions require it.

You should also expect to make minor door or hinge adjustments over time in line with the manual, as timber structures naturally move slightly with changes in temperature and humidity.

In coastal or sea-air environments, exposed metal parts should be checked more regularly and protected with a rust-proof treatment such as WD-40 or another suitable anti-corrosion product.

Sauna heaters also require maintenance in line with the manufacturer manual. This normally includes periodically checking, washing, and restacking the stones, and in the longer term electric heater elements may need replacing if they wear out.

We do not currently offer a formal maintenance programme.

If your sauna has exposed or untreated exterior timber, use a breathable, UV-resistant and water-resistant exterior wood treatment. We recommend Tikkurila Valtti Plus Kesto or Tikkurila Valtti Plus Color. If you prefer a clear, natural finish, Osmo UV Protection Oil is a good option.

Apply the treatment after assembly and before regular use, then inspect the timber annually and re-treat it as required for the product and your site’s exposure.

For sauna-room walls, window frames and door frames, use Tikkurila Supi Sauna Finish or Tikkurila Supi Sauna Wax. For benches and backrests, use Tikkurila Supi Laudesuoja Bench Protection. Never use ordinary exterior paint, varnish or household wood treatments inside the heated sauna room.

If your sauna has factory-finished or specialist cladding, follow the supplied manual and do not overcoat it unless the manufacturer confirms the product is suitable.

These recommendations are general guidance. Check both the sauna manufacturer’s manual and the treatment manufacturer’s instructions, and satisfy yourself that the product is suitable for the timber and any existing finish before applying it. If you are unsure about a colour, request samples from the manufacturer or retailer and test one on a spare timber offcut or a small, inconspicuous area first.

Buy two 0.9-litre tins (1.8 litres total) of Tikkurila Supi Sauna Finish for the sauna-room walls and ceiling, and one 1-litre tin (1 litre total) of Tikkurila Supi Laudesuoja for the benches and backrests. For untreated exterior timber, buy either one 2.7-litre tin and one 0.9-litre tin (3.6 litres total) of Tikkurila Valtti Plus Kesto or two 0.75-litre tins (1.5 litres total) of Osmo UV Protection Oil Extra for the specified two-coat systems.

The buying calculation uses 9.6 m² interior requiring 1.38 litres, and 1.7 m² of bench timber requiring 0.24 litres, with 9.58 m² outside requiring 2.75 litres of Valtti or 1.22 litres of Osmo. It uses the lower published coverage rate and one coat inside, two coats on untreated exterior timber, with a 15% allowance. Glass, roof shingles or membranes, the underside and confirmed factory-painted trim are excluded.

These are conservative buying allowances. Follow the current label and technical sheet for the product you choose; if its coverage or coat count differs, use those figures instead.

Yes. Our traditional saunas are suitable for commercial use, and we already supply many commercial customers.

Commercial use requires a regular maintenance regime, as it would with any sauna. This includes cleaning the sauna, inspecting and maintaining the heater stones, and re-treating or painting the timber when required. The frequency will depend on usage, location and the manufacturer's maintenance instructions.
