Bespoke Garden Saunas - London, Essex & Home Counties

A bespoke garden sauna brings together luxury, wellbeing, and contemporary outdoor design, creating a private retreat that can be enjoyed throughout the year. At Decking Gurus, we design and construct premium outdoor saunas tailored to unique style of each property, blending Scandinavian-inspired craftsmanship with modern architectural detailing. Every installation carefully planned to integrate seamlessly with surrounding garden, whether positioned alongside Millboard decking terrace, swimming pool, garden room, or landscaped outdoor space. Based in Chadwell Heath RM6, serving London, Essex, Kent, Hertfordshire, Surrey, Berkshire, Buckinghamshire, Bedfordshire. 10+ years, 100+ projects, own team not subcontractors.

Every project begins with personalised design consultation, allowing us to create bespoke sauna tailored to exact requirements. Whether you are looking for compact two-person sauna, spacious family wellness suite, or fully integrated outdoor spa experience, we carefully consider layout, positioning, glazing, privacy, wind, levels, and surrounding landscaping to maximise both functionality and visual impact. Result is beautifully crafted garden sauna that feels like natural extension of your home. CAD + 3D visuals show sauna, deck, pergola, shower, and planting together — you see wellness retreat before we build.

We don't build timber sheds that rot. We build steel structure that lasts, with proper sauna-grade timber inside where it matters:

• External: 3mm folded steel structure, hot-dip galvanised + powder coated to 80 microns, 25yr anti-corrosion. Finished with Millboard Envello Shadow Line+ cladding matching your decking, same RAL 7016/9005/9003 palette as pergola, kitchen, seating, planters. No hardwood that greys and splits. Built in Essex, Not On Your Lawn — fabricated in workshop, installed in days.

• Wall build-up: 100mm insulation, vapour barrier, ventilated cavity. Built for year-round UK use, -5 to 90C. Walls stay dry, no condensation inside steel. Precision engineered for structural stability, not timber studwork that moves.

• Inside: sauna-grade Western Red Cedar or Thermo Aspen, never cheap pine. Floating benches, concealed fixings, 28mm thick T&G, rounded edges. Smells right, feels right, no resin burn. Panoram ic glazing with low-E double glazed units, toughened safety glass, black frame to match exterior.

• Heater: Harvia electric 6-9kW or wood-burning with external feed, properly vented. Intelligent ventilation gap under benches, ceiling vent, delivers authentic Scandinavian experience with even heat distribution 70-90C. Harvia warranty included.

Inside, every sauna handcrafted using carefully selected sauna-grade timber, creating warm, inviting atmosphere that reflects quality expected from luxury wellness space. We offer complete flexibility when it comes to interior design, including floating benches at 450mm and 900mm heights, ergonomic backrests, panoramic glazing, feature lighting, hidden 24V LED illumination under benches, premium Harvia heaters with built-in controls, intelligent ventilation systems, and bespoke storage for towels. Every element selected to create authentic and relaxing sauna experience.

Our bespoke saunas can be incorporated into complete outdoor living environment, creating private wellness retreat tailored to lifestyle. Many projects include Millboard decking, bespoke steel pergolas with retractable fabric, outdoor kitchens with Dekton worktops, changing rooms with Millboard cladding, cold plunge pools, outdoor showers with hidden drainage, hot tubs sunken into deck, relaxation terraces with hydraulic seating and Sunbrella cushions, privacy screening 20-40mm gap, and professionally designed landscaping. By combining these elements into one cohesive design, we create luxurious outdoor spaces that can be enjoyed throughout every season. One team designs sauna and deck together — every line matches.

Every installation completed with meticulous attention to detail, ensuring highest standards of craftsmanship throughout entire build process. From precision structural steel construction and concealed detailing to premium glazing systems and architectural finishes, our experienced team delivers garden saunas that are both visually striking and built to provide decades of reliable performance. Quality, durability, and exceptional workmanship at heart of every project. Electrics chased inside steel, no visible trunking. Drainage engineered so water never sits under sauna.

Best for wellness-focused gardens — 2x2m compact fits most London gardens, no planning under 2.5m height. Best for family homes in Essex — 2.4x3m seats 4-6, with changing area. Best for hospitality — commercial spec with Harvia Cilindro and enhanced ventilation. Timber looks good for a year. Steel looks good for 25 — outside stays perfect, inside stays authentic cedar.
