Custom Saunas

There is nothing better than stepping into a hot, authentic cedar sauna after a long day in the Pacific Northwest weather. J Plus Contracting designs, builds, and installs custom residential saunas throughout Lake Cowichan, Duncan, and the Cowichan Valley, tailored precisely to your property and lifestyle.

We use clear, sustainably sourced Western Red Cedar to craft bespoke indoor wellness rooms and standalone outdoor sauna cabins. Every build prioritizes airtight vapour barriers, proper multi-level benching, high-grade foil insulation, and balanced passive airflow so your sauna heats quickly, holds high temperatures, and stays efficient in wet, cold seasons.

Our custom sauna builds include:

- Outdoor Sauna Cabins & Sheds: Free-standing backyard retreats, modern cube builds, and traditional timber structures engineered to weather Island rain and cold.

- Indoor Home Saunas: Custom-fitted basement conversions, ensuite wellness spaces, and spare-room retrofits with seamless moisture-proofing.

- Wood-Fired & Electric Heating: Expert installation of trusted electric sauna heaters or traditional wood-burning stoves with proper thermal clearances and rock trays.

- Ergonomic Cedar Interiors: Smooth Western Red Cedar benches, backrests, duckboard flooring, and soft ambient lighting designed for comfort and steam flow.

- Full Plunge & Deck Integration: Complete site builds connecting your sauna to outdoor showers, cold plunge tubs, and cedar deck platforms.

Every sauna build starts with an on-site visit to discuss layout, electrical capacity, and heating preferences. From custom framing and foil sealing to the final cedar trim, we build solid, high-performing saunas made for a lifetime of heat.
