Michael and his crew built us a stunning deck around our cold plunge and sauna setup that feels like a private wellness retreat. The craftsmanship is top-notch and they clearly understood how to balance aesthetics with the drainage and utility needs of a cold plunge.

MG Construction handled every detail of our backyard transformation, from the pergola framing to the cold plunge surround and electrical rough-in coordination. The finished space looks like something out of an architectural magazine, and it all came in on the timeline Michael promised.

What sets MG Construction apart is that Michael is a third-generation contractor who genuinely knows how structural decking and cold plunge installations interact - he flagged a drainage slope issue before it became a problem. That level of experience is rare in Los Angeles and saved us a costly fix down the road.

Frequently Asked Questions
Do I need a permit to install a cold plunge in my Los Angeles backyard?
In most cases, a freestanding cold plunge tub does not require a building permit in Los Angeles, but if it is being integrated into a new deck structure or connected to permanent plumbing, permits will likely be required. MG Construction & Decks is familiar with LADBS requirements and can coordinate permit applications as part of the overall deck or patio project. They recommend addressing permitting early to avoid delays in your project timeline.
How much does a cold plunge installation typically cost in the Los Angeles area, and how long does it take?
In the Los Angeles market, a cold plunge installation integrated into a custom deck or patio environment typically ranges from $8,000 to $25,000 or more depending on the complexity of the surrounding structure, materials, and chiller unit selected. MG Construction & Decks generally completes combined deck and cold plunge surround projects within three to six weeks once permits are approved and materials are on site. California labor costs and permit fees are factored into all project estimates upfront.
What does MG Construction & Decks actually build around a cold plunge installation?
MG Construction & Decks specializes in creating the complete outdoor environment that supports a cold plunge, including custom wood or composite decking, privacy pergolas, drainage-optimized concrete or tile surrounds, and outdoor shower stations. They also build integrated outdoor kitchens and seating areas so the cold plunge becomes part of a cohesive wellness and entertaining space rather than an isolated fixture. Their team coordinates with plumbers and electricians to ensure all mechanical connections are seamlessly incorporated into the finished design.
How do I maintain a cold plunge installed in a Los Angeles outdoor environment?
In the Los Angeles climate, UV exposure and ambient heat are the primary maintenance challenges for outdoor cold plunges, so keeping the chiller unit shaded and using a quality cover when the plunge is not in use significantly extends equipment life. Water chemistry should be checked weekly using a simple test kit, and filters should be cleaned or replaced on the schedule recommended by your chiller manufacturer. MG Construction & Decks designs surrounding structures with maintenance access in mind, so reaching filters, drains, and plumbing cleanouts is never an obstacle.
How do I choose the right cold plunge size and chiller unit for my backyard?
The right cold plunge size depends on how many people will use it regularly and how much space is available within your planned outdoor layout - most residential installations range from 50 to 150 gallons. Chiller unit capacity should be matched to the water volume and your target temperature range, typically 39 to 55 degrees Fahrenheit, with higher-capacity units recommended for larger tubs in warm climates like Los Angeles. MG Construction & Decks works with clients during the design phase to select equipment that fits both the spatial footprint and the long-term performance expectations of the project.
What site preparation is required before MG Construction & Decks can install a cold plunge setup?
Before installation begins, the site needs a level and stable foundation - either an existing concrete slab, compacted gravel base, or a new deck structure engineered to support the weight of a filled cold plunge, which can exceed 1,500 pounds. Access to a dedicated electrical circuit, typically 120V or 240V depending on the chiller, and a nearby drain or planned drainage route are also essential prerequisites. MG Construction & Decks conducts a thorough site assessment at the start of every project to identify any grading, electrical, or structural work needed before the cold plunge and surrounding build can proceed.
