SaunaLife Barrel Shower Model R3
Choose your option
When you've invested in a premium outdoor sauna or poolside retreat, you deserve an outdoor shower that matches that level of quality and craftsmanship. The SaunaLife Rain Series delivers exactly that — a luxury outdoor shower experience built around our flagship barrel shower, the R3 model.
The SaunaLife Rain Series represents a completely different approach to outdoor shower design, combining stunning aesthetics with genuine durability that stands up to years of outdoor use. From post-sauna cool-downs to post-swim rinses, this outdoor shower kit turns a basic function into a striking feature of your backyard.
The barrel shower design offers something you won't find in conventional outdoor shower kits: a distinctive architectural presence that complements your sauna or pool area while providing a fully enclosed, weather-resistant showering experience. And because it's engineered specifically as an outdoor sauna shower companion, the SaunaLife RAIN Series integrates seamlessly into your wellness routine.
The rich, golden tones of the Thermo-Spruce shower construction create a natural visual harmony with traditional sauna architecture, making your entire outdoor setup feel cohesive and intentional.

The Thermo-Spruce Shower Advantage
Here's where the SaunaLife Rain Series truly separates itself from other outdoor shower options on the market: the revolutionary Thermo-Spruce shower material that forms the foundation of every barrel shower we build.
Most wood outdoor shower designs rely on cedar, and while cedar has been the traditional choice for outdoor applications, it has significant limitations when exposed to constant moisture. That's why we've gone a completely different route with our Thermo-Spruce barrel construction.
Thermo-Spruce undergoes a specialized thermal modification process that fundamentally changes the wood at a cellular level. Through carefully controlled heat treatment, the wood's structure becomes incredibly stable and naturally resistant to rot, decay, and moisture damage — without any chemicals or toxic treatments whatsoever. This results in a durable outdoor shower that can last up to two times longer than comparable cedar structures.
Consider what this means for your investment. While a standard cedar outdoor shower may begin to show wear, warping, or rot over time, a Thermo-Spruce shower is designed to retain its structural strength and attractive appearance for many years with minimal upkeep.
The construction of the SaunaLife R3 barrel shower uses substantial 1.65-inch thick Thermo-Spruce staves that create a robust, weather-resistant shell. These thick staves provide excellent insulation properties (higher R-value than standard lumber), which means your backyard shower stays more comfortable even when outdoor temperatures fluctuate.
The thermal modification process also makes the wood dimensionally stable, so you won't experience the warping, twisting, or splitting that plague conventional wood outdoor shower installations.
And let's talk about aesthetics — the Thermo-Spruce shower wood develops a rich, warm honey-gold color through the thermal process that only deepens and becomes more beautiful with age. Unlike cedar that grays and weathers unevenly, your barrel shower maintains its stunning appearance year after year.

Hot and Cold Outdoor Shower Features
A truly luxurious outdoor shower needs more than just good looks and durability — it needs to function beautifully every single time you use it. That's where the hot and cold outdoor shower system in the Rain Series really shines.
Many outdoor shower kits on the market only offer cold water connections, which might be refreshing after a pool swim but feels less than ideal after a hot sauna session. The SaunaLife Rain Series is fully plumbed for both hot and cold outdoor shower operation, connecting directly to your home's standard residential water lines. With full control over the water temperature, you can tailor each shower to your mood, from a brisk, energizing splash to a calming, warm soak.
The overhead fixture is a generous 7-inch outdoor rain shower head that provides a luxurious cascade of water, mimicking the feel of natural rainfall. There's something incredibly soothing about standing under a rain-style shower head in an outdoor setting. It enhances that connection to nature while delivering the comfort and coverage you'd expect from a high-end indoor shower.
Your hot and cold outdoor shower system also includes a handheld spray attachment, giving you the flexibility to rinse off feet, clean the shower floor, or direct water exactly where you need it. This dual-fixture setup means your barrel shower adapts to whatever your needs are at the moment.
The floor design deserves special mention. We've integrated drainage channels directly into the Thermo-Spruce floor, ensuring water flows efficiently without pooling. The system includes a matching wooden floor mat that provides a comfortable, slip-resistant standing surface while allowing water to drain freely beneath. And for those final touches of convenience, the backyard shower includes integrated robe hooks so you always have a dry place to hang your towel or robe while you shower.

Installation and Acquisition: Your Outdoor Shower Kit
Many people hesitate to add an outdoor shower because they’re unsure about the installation process. Will it require professional contractors? Weeks of construction? Complex plumbing work that needs extensive permitting?
The beauty of the outdoor shower kit approach is that SaunaLife has engineered the R3 to be surprisingly simple to install. The barrel shower arrives as a modular outdoor shower kit with pre-cut, precision-milled components that fit together systematically. Two adults with basic tools and moderate DIY skills can typically complete the assembly in a single afternoon.
The Thermo-Spruce staves are numbered and designed to interlock, creating the distinctive barrel shape without requiring specialized carpentry knowledge. The roof panels fit into place with similar simplicity.
The plumbing hookup is equally thoughtful. The SaunaLife R3 includes a concealed exterior plumbing box that houses all your water connections, keeping the functional elements hidden while maintaining easy access for maintenance. You'll connect your hot and cold water lines to standard fixtures inside this box, and the system integrates seamlessly with the overhead and handheld shower components.
If you're ready to buy outdoor shower equipment that transforms your outdoor living space, the Rain Series represents a genuine investment in daily luxury. This is a wood outdoor shower that becomes a permanent feature of your property — one that adds both functional value and aesthetic appeal that guests will notice and admire.
When you're ready to buy outdoor shower products of this caliber, you're investing in years of enhanced outdoor living. Every time you step into your backyard shower after a sauna session or a swim, you'll appreciate the decision to choose quality, durability, and genuine luxury.
The outdoor shower kit includes everything you need except the plumbing connections themselves, and most homeowners find they can complete the hookup without professional help. Of course, if you prefer to have a plumber handle the water line connections, that's a quick job for any licensed professional.
