Loyly Sauna

Löyly Sauna is a Norfolk-based sauna builder run by Andy Armshaw and a small team of craftsmen, handbuilding bespoke mobile trailer saunas, horsebox conversions, and a new cabin range from their workshop near Norwich. Builds feature thermowood (thermo aspen and thermo pine) interiors and exterior cladding, natural wool insulation, and Harvia or Narvi wood-fired stoves, with electric options also available. The team handles the full process from design consultation through to delivery and on-site installation across the UK, with commercial and personal builds completed as far afield as Scotland and Devon. The cabin range — spanning 2–3 to 6–8 person sizes — is suited to homeowners seeking a permanent garden sauna, while the trailer and horsebox builds suit mobile sauna businesses.
