There’s a quiet revolution happening in the backyards of America, and it involves a surprising combination of raw steel, reclaimed wood, and crystal-clear water. The barndominium—once a humble structure built for housing livestock and equipment—has evolved into the ultimate lifestyle building. When you shrink that concept down and plant it next to a swimming pool, you get something truly magical: the barndominium pool house.
As an architectural designer who has spent the last fifteen years specializing in outdoor living spaces, I’ve watched this trend move from a quirky niche to a highly sought-after feature that adds both functionality and massive property value. But unlike a traditional pool house—which often feels like an afterthought or a simple cabana—a barndominium pool house carries weight. It has presence. It merges the rugged, utilitarian soul of rural architecture with the sleek, carefree ethos of a luxury resort.
If you are considering adding a pool house, or if you’re building a custom pool and want something that stands out from the standard stucco boxes, let’s walk through how to nail the design—both inside and out—so that your space feels less like a “pool shed” and more like a full-blown retreat.
Why the Barndominium Aesthetic Works for a Pool House
The beauty of the barndominium style lies in its honesty. The structure typically features exposed post-and-beam construction, high ceilings, and large, sliding doors that erase the line between indoors and out. For a pool house, this is architectural gold.
Swimming is a sensory experience. You want the space to feel open, breezy, and durable. Traditional drywall and narrow hallways feel claustrophobic when you’re dripping wet, wrapped in a towel, trying to grab a snack. But a barndominium pool house? It embraces materials that laugh in the face of moisture—steel, concrete, cedar, and stone.
Moreover, the scale works. A standard pool house can sometimes look like a tiny afterthought next to a sprawling home. But the barn shape, with its distinctive roofline and verticality, commands attention. It becomes a focal point rather than an accessory. Whether you go for a classic gable roof or a modern single-slope (shed) design, the structure frames the pool area beautifully, giving the entire backyard a sense of purpose.
Designing the Exterior: Where Rustic Meets Refined
When approaching the exterior, I always tell clients to think about context. Are you building this on a sprawling rural property, or are you in a suburban neighborhood trying to inject some modern farmhouse flair? The materials you choose will dictate how the structure ages.
The Shell: For authentic barndominium style, standing seam metal roofing is non-negotiable. It’s durable, sheds water effortlessly, and develops a beautiful patina over time. For the siding, you have options. Corrugated metal is classic and cost-effective, but I’m partial to a mix of materials. Consider using horizontal board-and-batten siding on the lower third of the walls to add texture, paired with metal above. This breaks up the massing of the building and makes it feel more architectural.
The Doors: If there is one area where you should splurge, it is the overhead doors. A true barndominium vibe often includes a functional, insulated overhead garage door. Imagine opening a 12-foot-wide glass or aluminum overhead door that transforms the entire pool house into an open-air pavilion. This is the ultimate “indoor/outdoor” living feature. When the door is up, you have a shaded porch that opens directly to the pool deck. When it’s down (especially if you opt for glass panels), you maintain the view but can control the climate inside for guests or storage.
The Covered Porch: Don’t underestimate the value of a deep overhang. In barndominium design, the roof extends far beyond the walls. Use this to your advantage. A wraparound porch or a substantial covered area provides essential shade for lounging. I like to spec tongue-and-groove cedar ceilings under these porches. It adds warmth to the exterior and creates that classic farmhouse feel that contrasts beautifully with the industrial steel.
Indoor Design Inspiration: The Wet Room Concept
Let’s move inside. A standard pool house usually consists of a bathroom and maybe a changing area. A barndominium pool house can be so much more. Depending on the square footage, it can function as a guest suite, a home gym, or a full-blown entertainment hub.
The Flooring Situation: Forget carpet. Forget polished concrete that gets slippery. The best flooring for a barndominium pool house is either large-format porcelain tile that mimics limestone or stained concrete with a heavy-grit additive for traction. If you want to keep that rustic warmth, consider a heated microcement finish. It’s seamless, waterproof, and has that organic, earthy texture that aligns with the barn aesthetic. You are going to have wet feet, chlorine drips, and sunscreen spills; the floor needs to handle it all without showing wear.
The Bathroom and Changing Area: I am a huge advocate for the “wet room” concept in this setting. Instead of a cramped shower stall separated by glass doors that will inevitably get hard water stains, design a large open area. Use a linear drain and floor-to-ceiling waterproof panels or textured tile. A rainfall showerhead paired with a handheld sprayer allows swimmers to rinse off before jumping in the pool or to wash off the chlorine after. Because we are leaning into the barndominium aesthetic, use industrial-style fixtures—black iron pipes for towel bars, exposed shelving made of pipe and reclaimed wood, and a vanity crafted from a vintage metal locker or a live-edge slab.
The Utility Kitchen: This isn’t your gourmet indoor kitchen, but it shouldn’t be a wet bar with a mini-fridge either. To truly make this space functional, install a “dirty kitchen” setup. Think commercial-grade materials: a stainless steel countertop (which is antibacterial and indestructible), a deep farmhouse sink big enough to rinse off pool toys or fill coolers, and an ice maker that can keep up with summer parties. Beverage coolers are great, but a dedicated ice machine and a small dishwasher drawer for washing glasses are the luxury touches that elevate the space.
Climate Control: One mistake I see often is treating the pool house like a standard addition. If you have an overhead door or large sliding glass walls, standard HVAC struggles. Consider ductless mini-split systems. They are efficient, quiet, and the wall-mounted units don’t take up floor space. They also handle humidity better than central air, which is critical when you have a large volume of water (the pool) and people going in and out constantly.
The Great Outdoors: Bridging the Gap
The space between the pool and the pool house is just as important as the structures themselves. The goal is flow.
The Breezeway: If your pool house is detached from the main residence, consider the path. A concrete walkway is functional but boring. I prefer to create a “breezeway” effect using permeable pavers set in a herringbone pattern, or large flagstone steppers set in crushed gravel. This allows water to drain naturally and keeps the area from becoming a muddy mess. Line this path with low-voltage landscape lighting on dimmers to create ambiance for night swimming.
The Outdoor Kitchen Expansion: While the interior might have a utility kitchen, the real cooking should happen outside adjacent to the pool house. Build a masonry grill station or a pizza oven under the eaves of the barn roof. Use the same materials as the pool house—perhaps a stone base with a steel hood vent. This creates a cohesive zone where the cook isn’t isolated from the party. I also recommend installing a pass-through window from the interior kitchen to the exterior grill area. A simple window with a bar top on the outside allows for easy serving and creates another connection point between the indoor amenities and the pool deck.
Specialized Spaces: Beyond the Bathroom
For those who have the square footage, the barndominium pool house can serve multiple purposes that justify the investment.
The Bunk Room: If you entertain frequently, turning part of the pool house into a bunk room is a game-changer. Imagine built-in, heavy-duty wooden bunks with industrial railings. It’s a safe, fun space for kids to dry off and hang out without tracking water through your main house. Use indoor/outdoor fabric for the cushions and curtains so everything remains moisture-resistant.
The Equipment Room: Let’s talk about the ugly stuff—pool equipment. In traditional setups, the pump and filter are often hidden behind a bush or in a plastic box. In a barndominium pool house, you can allocate a small, sound-dampened mechanical room. This keeps the pool equipment out of sight and, more importantly, muffles the noise of the pump so you can enjoy peace and quiet by the water. Plus, having the equipment housed in a climate-controlled (or at least weather-protected) space extends its lifespan significantly.
The Sauna or Cold Plunge: The barndominium aesthetic is actually a perfect match for wellness trends. The raw, organic materials—cedar, stone, steel—are the same ones used in high-end spa design. If space allows, tucking a barrel sauna or a cold plunge tub into the corner of the pool house creates a four-season sanctuary. It turns your backyard into a private spa that you can use even when the main pool is too cold for swimming.
Material Selection: Durability is Key
If you take nothing else away from this, remember that a pool house is a hostile environment. Sun, chlorine, and humidity will destroy cheap materials quickly.
For countertops, avoid marble or porous granite. Quartz is durable, but some formulations can yellow in direct UV light. I prefer poured concrete sealed with a high-grade marine epoxy, or stainless steel. Concrete fits the industrial farmhouse vibe perfectly and can be custom-colored to match the barn’s aesthetic.
For cabinetry, skip the big box store MDF. One leak, and it swells like a sponge. Opt for marine-grade plywood boxes with solid wood or thermofoil fronts. Better yet, use open shelving made of wire baskets or reclaimed wood. In a space this casual, open shelving encourages the use of durable glassware and easy-to-grab towels.
For lighting, go with vintage-inspired gooseneck lights on the exterior. On the interior, I love using large, galvanized metal shades over the kitchen area and woven rattan pendants over the lounge area to soften the industrial edge. All lighting in the immediate vicinity of the pool must be low-voltage and properly grounded for safety, but don’t let that limit your style—there are incredible rated fixtures now that look like antique barn lights.
Bringing It All Together
Designing a barndominium pool house is ultimately about balancing two opposing forces: the ruggedness of a working barn and the relaxation of a resort. The magic happens when the structure feels substantial enough to stand on its own, yet open enough to invite the outside in.
I recently finished a project for a client who was initially just looking for a place to store pool equipment and a bathroom. We ended up building a 1,200-square-foot structure with a 14-foot overhead glass door, a full outdoor kitchen, and a loft for overflow guests. They now host all their family gatherings there. The main house becomes a quiet retreat while the pool house acts as the heartbeat of the property.
When you are planning your design, think about your own rhythms. Do you host large parties where you need a separate bar and plenty of changing space? Or do you want a quiet sanctuary for morning laps and evening cocktails? The beauty of the barndominium style is its flexibility. You can scale it down to a simple, beautiful shed with a half-bath and a copper shower, or you can scale it up to a full guest house that rivals the main residence.
Invest in the structure first—the bones, the roof, the doors. You can always add a fancy backsplash later, but moving a wall or upgrading insulation is a nightmare once the build is complete. And don’t be afraid to let the materials age. Rust on a corrugated panel, weathering on a cedar plank—these imperfections add character. They tell the story of summers spent splashing in the water and evenings gathered under the barn roof, watching the sun set over the pool.
Ultimately, a barndominium pool house isn’t just an addition to your property; it’s a lifestyle upgrade. It takes the hassle out of entertaining, gives you a dedicated space to relax, and adds an architectural anchor to your landscape that is as beautiful as it is functional. Whether you are deep in the countryside or carving out a slice of farmhouse life in the suburbs, this is one trend that has proven it has staying power—because nothing beats the feeling of walking from a cool, steel-framed sanctuary into the warm sun and diving straight into the water.
