The San Clemente
Where sleek simplicity meets sophisticated style.
The San Clemente is proof that great design doesn't require a lot of space. This compact rectangular plunge pool, at just 8 feet wide and 12 feet long, delivers a clean, contemporary aesthetic with a remarkably efficient footprint. At 3.5 feet deep throughout, it's perfectly engineered for cooling off, relaxing after a long day, or enjoying a hydrotherapy upgrade without needing a large backyard.
The linear form of The San Clemente pairs beautifully with modern architecture and urban outdoor spaces. Its proportions make it an ideal canvas for the Water Feature Package, a sheer arc waterfall and tanning ledge bubbler create a visual and acoustic centerpiece that belies the pool's modest size. For those seeking a more therapeutic experience, the Hydrotherapy Package transforms this compact design into a full-featured aquatic wellness retreat.
The Avalon Mini
A perfect circle of calm, made for the backyard that thinks big.
There's something timeless about a round pool. The Avalon Mini brings that classic form to life in a compact 12-foot diameter, a surprisingly spacious plunge experience wrapped in one of the most visually striking shapes in residential pool design. At 3.5 feet deep and 115 square feet, this pool is as functional as it is beautiful.
The circular form of The Avalon Mini creates a natural focal point in any outdoor space. It complements Mediterranean, Spanish, and traditional architecture especially well, but looks equally stunning in a minimalist landscape setting. The curved perimeter makes it an inviting place to gather, equally suited for solo relaxation or entertaining a small group. Add the Light & Sound Waves Package and the Avalon Mini becomes an illuminated, music-filled oasis that transforms your backyard after dark.
The Monterey
Classic California cool, designed for the modern outdoor room.
Named for one of California's most beloved coastal escapes, The Monterey is a refined rectangular plunge pool with a wider, more commanding presence. At 15 feet long and 13 feet wide, the near-square proportions create a distinctly open feeling, more like a private lagoon than a lap pool. With 145 square feet of water surface and a depth range of 3.5 to 4 feet, The Monterey offers genuine versatility in how it's enjoyed.
The Monterey's balanced dimensions make it one of the most upgrade-friendly designs in the Plunge Series. The wider footprint provides ideal geometry for the Spa Hydrotherapy Package, the attached spa sits naturally at one end, creating a seamless indoor/outdoor wellness space. The proportions also make this the most visually symmetrical of the rectangular designs, lending itself to formal landscape arrangements and covered patio structures.
The Hermosa
Intimate by design. Extraordinary by experience.
Hermosa means 'beautiful' in Spanish, and this pool earns that name. At 10 feet wide and 15 feet long, The Hermosa achieves an ideal balance between spaciousness and intimacy. The longer, narrower proportions accommodates a full tanning ledge, water features, and hydrotherapy seating with ease. At 150 square feet, it's one of the more spacious options in the Plunge Series despite its slim profile.
The Hermosa is a particular favorite for homeowners who want the look and feel of a full pool without the footprint. Its elongated form is naturally suited to the Swim Gym packages, both the Mini and Deluxe options integrate seamlessly with its proportions, allowing for genuine resistance swimming in a compact space. The narrower width also means The Hermosa fits gracefully alongside structures like covered patios, outdoor kitchens, or privacy walls.
The Big Sur
Wide open water. Endless possibilities.
Inspired by the dramatic Big Sur coastline, this is the Plunge Series at its most expansive. At 20 feet long and 10 feet wide with 176 square feet of water surface, The Big Sur delivers maximum water presence without the cost of a full-size pool. Ranging from 3.5 to 4 feet deep, it's deep enough for genuine swimming when paired with the Swim Gym Deluxe Package and the BaduJet Turbo in-wall system.
The Big Sur's generous proportions create room for a full tanning ledge, hydrotherapy seating, and swim resistance, all in one pool. The wide, open water surface makes it feel far larger than its footprint suggests, and the rectangular form lends itself to both modern and traditional landscapes. This is the design for the homeowner who wants maximum water presence and functionality at a value-forward price point.
The Avalon
Elegant. Expansive. The crown jewel of the Plunge Series.
The Avalon is the Plunge Series at its most generous. With a 16 foot diameter and up to 201 square feet of water surface, this circular pool brings a resort-quality presence to your backyard without the footprint of a full-size swimming pool. Ranging from 3.5 to 4 feet in depth, The Avalon provides enough volume for true hydrotherapy jets, a built-in tanning ledge, and even an optional attached spa, making it the most versatile design in the lineup.
The Avalon's generous proportions create room for multiple lounging configurations, from relaxing on the tanning ledge to standing in the deeper center zone or enjoying the perimeter seating area with hydrotherapy jets. Its circular shape creates a natural gathering point that works beautifully in large and mid-size yards alike. This is the design for the homeowner who wants a premium experience at a value forward price point.

Frequently asked questions
Plunge pool questions, answered for Upland/High Desert.
What is a plunge pool?
A plunge pool is a compact, shallow pool designed for cooling off, relaxing, and hydrotherapy rather than swimming laps. Typically ranging from 8 to 20 feet in length, plunge pools are perfect for small yards or as a secondary water feature. Despite their smaller size, they're built with the same gunite construction and craftsmanship as our full-size pools.
How much does a plunge pool cost?
Pricing varies based on the model you choose, any upgrade packages, finishes, and site conditions. During your free consultation, our Upland/High Desert team will provide a detailed estimate based on your specific selections.
How long does it take to build a plunge pool?
Plunge pools typically take 4 to 8 weeks to build, faster than a full-size pool due to the smaller footprint. Design, engineering, and permitting can add 2 to 4 weeks before construction begins. Weather and supply availability can also affect the timeline.
Can I swim in a plunge pool?
While plunge pools aren't designed for traditional lap swimming, you can add a Swim Gym package that creates a swim current, allowing you to swim in place. This turns even the smallest plunge pool into an effective exercise pool.
Can I add a spa to my plunge pool?
Yes. The Spa Hydrotherapy Package adds integrated spa jets and hydrotherapy features to your plunge pool, combining the benefits of a pool and spa in one compact footprint.
Do plunge pools add home value?
Yes. Any well-built gunite pool adds property value, and plunge pools are increasingly popular with homebuyers who want a pool but have limited space. A plunge pool can be a strong selling point, especially in markets where outdoor living is valued.
