Designer Raili Clasen enveloped this Pasadena pool house in floor-to-ceiling windows, letting light in and creating flow with the yard.

"[The windows] allow visitors to peek inside the indoor lounge space, outfitted with midcentury modern furnishings and a big, comfy sofa for guests to escape the heat," Clasen says. "We kept the style of the main house for the interiors of this cute bungalow."

On a more practical note, weather-resistant fabrics are key in a pool house and ensure that furniture can stand up to the elements.

"[One of my favorite tricks] is using performance fabrics on all upholstery," says designer Jean Liu. "This part of the house is one where fun is the most important activity, and no one needs to worry about spills or stains."

Carving out a cozy spot for after-swim naps is a go-to move for designer Christina Kim, as seen in this beachy project.

"If space allows, built-in bunk beds are a fun, space-saving option—great for kids and spontaneous weekend guests," she adds. "Otherwise, a deep sofa or a cushy chair-ottoman combo in a performance or natural fiber fabric works beautifully. I like to layer in patterned pillows or a vintage quilt for personality."

Doors are an easy way to pack personality into your pool area.

"Creating an entire mini-house behind these barn doors was the goal for this pool house," Clasen says. "When open, family and friends can shower, lounge on the giant sofas, and grab a drink from the bar. When closed, the space is a great backdrop for the beautiful pool."

If you have a big yard, then take advantage of the extra space. Here, designer Mark Langos added a dramatic central porch to the pool house where guests can enjoy views of the surrounding mountains.

"[It] can be fully enclosed or completely opened to the elements, creating a seamless transition between the living space and the outdoors," Langos says. "Once open, the living room flows effortlessly onto the patio, making the entire pool house feel as if it’s part of the landscape."

Pools are inherently joyful—whether you're having a party or just lounging. Add to that energy with some statement artwork.

"This pool house screams playtime with a large neon sign lighting up the background and can be seen from all angles of the pool," Clasen says. "Our inspiration came from the client's love of music—especially rock and roll."

To create cohesion with the main home, treat your pool house with similar exterior features—especially through landscaping and architectural elements.

"For example, if a specific door detail is found inside the house, it would be nice to see it applied to the pool house," Liu says.

On the flip side, if you want it to feel like a true getaway, then your pool house can have a completely different aesthetic from the main home.

"We added this pool house to have its own style [and] look like a structure that has been there forever—[like] a barn on the property," Clasen says. "This houses an extensive wine collection, a massive sofa for group TV watching, and its own bath and shower."

Outdoor drapery is a great way to evoke a breezy, summer feel.

"Use it to soften the structure, add shade, and create a little movement when the wind picks up," Kim says. "It instantly makes the space feel more inviting."

Kim loves accordion or flip-out windows, as they add an airy vibe.

"They create an easy pass-through for drinks and food, which makes entertaining feel laidback and fun," she notes. "It’s a simple detail that goes a long way in making the space feel connected to the pool."

Hardscaping elements like pavers help create a clear flow between lounging, dining, and pool zones.

"I like using oversized stone or concrete pavers with grass or gravel joints to keep things feeling relaxed but intentional," Kim says. "It’s a subtle move that makes the whole area feel more pulled together."
