Every BYSP sauna is equipped with an IKI brand stove — the gold standard in authentic Finnish sauna heating. Choose between the timeless ritual of a wood-fired stove or the convenience of a WiFi-enabled electric unit.

Why IKI? Each stove is engineered with a large rock mass and a uniquely effective design that distributes heat evenly throughout the sauna. The result is a fully balanced, deeply restorative heat — the kind you’d expect in a world-class Nordic sauna.

For those who choose electric, the WiFi control option lets you program and even start your sauna remotely, so it’s ready the moment you are. Tradition, technology, and performance — seamlessly combined.

Every BYSP sauna is finished with a standing seam steel roof, combining timeless design with unmatched durability. Unlike shingles or lightweight alternatives, standing seam panels lock together in continuous seams, creating a watertight barrier that stands up to the harshest weather conditions.

The benefits are clear:

• Exceptional Longevity — a roof built to last 40+ years with minimal maintenance.

• Weather Resistance — sheds snow and rain effortlessly while protecting against leaks.

• Energy Efficiency — reflective properties help regulate temperatures and reduce heat loss.

• Clean, Modern Look — sleek lines complement both natural and contemporary settings.

Strong, efficient, and visually striking — your sauna’s roof is built to perform as beautifully as it looks.

Every BYSP sauna includes a privacy-tinted window to let in natural light without compromising comfort. From there, the design is yours to shape — window size and placement are fully customizable across all models. Choose from subtle accent windows, larger openings, or even a floor-to-ceiling glass wall that transforms your sauna into a stunning architectural feature.

Every BYSP sauna includes a complete interior and exterior lighting package. Inside, fully dimmable under-bench lighting creates a soft, calming glow that elevates the sauna atmosphere. On the exterior, halo pot lights provide gentle, even illumination — extending the experience into the evening while keeping the mood relaxed and inviting.

Every BYSP sauna is constructed with R14 Rockwool insulation and a full vapor barrier system to ensure superior heat retention and authentic steam. The insulation delivers faster heat-up times, lasting warmth, fire safety, and moisture resistance, while the vapor barrier locks in steam and prevents heat loss. Together, they create the stable, high-performing environment that defines a true Nordic sauna.

Every BYSP sauna is built with a properly engineered ventilation system that ensures a steady flow of fresh air during each session. This circulation keeps the environment comfortable, safe, and energizing, while also allowing the sauna to “breathe” when not in use. By preventing excess moisture buildup, our ventilation system extends the life of your sauna and preserves the quality of the wood for decades of use.

No two backyards — or sauna visions — are the same. That’s why every BYSP sauna is fully customizable, from the exterior stain and window placement to the lighting accents and stove selection. Whether you prefer subtle privacy windows or dramatic floor-to-ceiling glass, warm cedar tones or darker modern finishes, wood-fired tradition or WiFi-enabled convenience, your sauna will be tailored to reflect your lifestyle and personal style.

Enhance your backyard spa with a seasonal outdoor shower, perfect for rinsing off between sauna rounds or after a cold plunge. Installed just outside your sauna, it provides a refreshing way to reset during the warmer months. Built with high-quality fixtures and simple connections, the shower is designed for easy use in spring, summer, and fall — but is not intended for winter operation.
