Large Sauna
A spacious Finnish sauna with a relaxation room. After your session, unwind right next door, warm and at ease.
Sauna and relaxation room in one
The Large Sauna has two rooms. The sauna room features aspen, a HUUM stove and two-tier benches with warm backlighting. Next door is a relaxation room with walls of spruce panels in an aged-wood look – a place to rest after your session before heading back into the heat.

FAQ
What you ask us most often
How much space does the sauna need?
The sauna itself has a footprint of 5 × 3 m.
What electrical connection do I need?
The HUUM DROP stove is rated at 9 kW and needs only a three-phase 16 A circuit breaker. We recommend a 5 × 2.5 mm² supply cable, or a heavier one if the sauna is further from the house – 5 × 4 mm² or 5 × 6 mm² (for a sauna 50 m away, for example, we recommend 5 × 6 mm²).
What foundations does the sauna need?
We'll send you the plans for the strip foundations as a PDF, or prepare them for you on a turnkey basis. Transport is always priced individually according to the site.
Do I need a building permit?
No. Under Czech regulations, a sauna is a structure nobody lives or sleeps in, so you don't need a building permit for it – just as with a garage, woodshed, terrace or pergola. A permit only becomes necessary if the building were to be used for sleeping or living in.
How long does it take to build the sauna?
We build the sauna within 1–3 months of the order going into production. Then we deliver it, set it in place and connect it.
How do I look after the sauna?
Care is simple and takes just a few minutes. We'll show you everything at handover, and you'll also receive a detailed maintenance guide.
- After every session: leave the door open to air the sauna, take out towels and seat covers, and wipe any water off the floor.
- Once a week or every 3–5 uses: wipe the benches with a damp cloth and a dedicated sauna cleaner, following the grain – no chlorine or harsh chemicals.
- Every 6–12 months: treat the benches with paraffin oil, lightly sand any discoloured areas with fine paper (120–180 grit) and check the stones in the stove – replace any that have cracked. Do not use varnish or synthetic coatings.
- Once a year, ideally in spring: check the larch façade, the roof and the glass and door seals, and clear leaves from the roof. We recommend having the stove's electrical connection checked by an electrician.
- Every 1–3 years: treat the façade with a UV-protective oil or an exterior wood stain.
Pour only clean water onto the stones – add essences to the bucket, never directly onto the stones.
