Custom Sauna Builder in Point Pleasant, NJ

For over 3 decades, Gambrick Construction has been the premier Custom Sauna Builder in Point Pleasant, NJ. We design and build luxury indoor and outdoor saunas throughout Ocean and Monmouth County.

You don’t want a flimsy kit that plugs into a wall. You want a permanent, custom-built retreat. We offer high-end customization that pre-fab companies can’t match, including heated stone floors, solid stone slab walls, custom glass & tile, and handmade walnut benches.

We handle the entire build, from the 240V electrical lines and commercial vapor barriers to the final wood-work. Building at the Jersey Shore requires more than just cedar boards; we engineer every sauna to withstand salt air and moisture, so you never have to worry about rot or mold behind your walls.

100% Bespoke & Handcrafted

Most saunas sold online are mass-produced in a factory and shipped in flat packs. Ours are built from scratch by Master Carpenters & Craftsmen right here in New Jersey. We don’t force you into a standard size; we build the sauna to fit you.

• Beyond Wood (Stone, Quartz & Tile): You aren’t limited to just cedar. We design modern saunas featuring solid Quartz slab walls, custom tile walls, and natural stone floors. Whether you want a backlit Quartz feature wall or a heated stone floor, we have the masonry skills to create a design that looks like a 5-star hotel spa.
• Built for Athletes & Tall Homeowners: Standard kits are cramped. We design custom-sized layouts with extra-long benches and high ceilings. Whether you need room for hot yoga, stretching, or just want to fully extend your legs without hitting the wall, we build the room to fit your body.
• Handmade Floating Benches: We don’t use flimsy pre-fab slats. Our woodworkers hand-build solid floating benches using thick Western Red Cedar or Black Walnut. We use hidden stainless steel fasteners so there are no exposed screw heads to burn your skin. The result is furniture-grade quality that feels solid under your weight.
• True “Bespoke” Design: Have an awkward corner, a slanted ceiling, or a window you want to work around? Because we build 100% custom, we can turn dead space into a functional spa. We scribe every board to match the unique curves and angles of your home.
• Glass-Walled Gym Integration: We often build glass-front saunas directly inside Home Gyms. This gives you that high-end “health club” look right in your own basement or garage.

Luxury Custom Indoor Saunas (Built-In)

Turning a basement corner or a spare room into a luxury spa takes more than just wood on the walls. We don’t just “install” a sauna; we fit it perfectly into your Master Bathroom or Home Gym design.

If you don’t manage the heat and humidity correctly, the steam will rot your framing and warp your drywall. Here is how we build our saunas to last.

• Proper Ventilation: A sealed box with a heater feels suffocating. We install intake and exhaust vents that cycle fresh air through the room. This keeps the oxygen levels high and the heat even, so you can relax longer without feeling dizzy.
• The Vapor Barrier: We install a commercial-grade foil vapor barrier behind the wood. This reflects the radiant heat back into the sauna and stops moisture from soaking into your home’s framing.
• High-Performance Insulation: We pack the walls with Rockwool or closed-cell spray foam. This keeps the 190°F heat inside the sauna where it belongs, so your electric bill stays low and your adjoining rooms stay cool.
• Premium Clear Woods: We source Clear Western Red Cedar, Hemlock, or thermally modified Ash. These are “knot-free” premium grades that resist rot naturally and remain cool to the touch.
• Waterproof Drainage: A real luxury sauna needs to be cleanable. We offer custom tile floors & stone slabs with a center drain, so you can hose down the sauna after a session.

Custom Outdoor Saunas & Cabins

Outdoor saunas are a massive trend in Spring Lake and Manasquan, especially near the pool. But the Jersey Shore weather is brutal on wood structures, so we build our saunas strong enough to withstand the elements.

• Weatherproof Envelope: To protect the cedar interior, we wrap the exterior in Tyvek and use durable siding materials like NuCedar, James Hardie Fiber Cement, or Shou Sugi Ban (charred wood).
• Insulated Roofing: We install a proper roof with architectural shingles or standing seam metal. We insulate the ceiling heavily so the heat stays down on the benches, not escaping through the roof.
• Options: Our outdoor saunas feature the exact same luxury amenities and high-end upgrades available in our custom indoor units. Things like wall to ceiling glass, walnut seating & accents, tile, stone, solid slabs & mood lighting.

 

Custom Features & Smart Tech

A custom sauna isn’t just a wood box with a heater. We design it with the modern amenities you expect in a high-end home.

• Smart Wi-Fi Heaters: You shouldn’t have to wait 45 minutes for the room to heat up. We install top-tier heaters from Harvia, Tylo, and Huum with Wi-Fi enabled controllers. You can start the heat while you’re driving home from the Manasquan Inlet, so it’s ready the second you walk in the door.
• Chromotherapy & Mood Lighting: Forget the harsh overhead bulb. We install dimmable LED strips under the benches and Chromotherapy (color therapy) lights. It creates a soft, relaxing glow that makes the room feel like a real spa.
• Panoramic Glass Walls: We don’t like dark, closed-in boxes. We frame floor-to-ceiling glass walls using tempered safety glass. This makes the sauna feel twice as big and lets you enjoy the view of your backyard or master suite.
• Multi-Level Ergonomic Seating: Heat rises. We build multi-level benches so you can choose your temperature. Sit up top for the intense 190°F heat, or lounge on the lower bench for a gentler sweat.

Frequently Asked Questions About Sauna Building

Do I need a permit for a home sauna in NJ?

Yes. Because it involves electrical work and structural framing, you need a permit. For outdoor saunas in towns like Bay Head or Brick, you also need a zoning permit to check setbacks. We handle all the paperwork for you.

Can you put a sauna in a basement?

Yes. Basements are actually a great spot because the concrete floor is already there. We just need to make sure we can vent the air properly and get a 240V wire from your electrical panel to the heater location.

How much does a custom built sauna cost?

A custom-built sauna is a construction project, not a product. Indoor conversions typically range from $15,000 to $25,000+ depending on glass and size. Outdoor sauna cabins typically range from $30,000 to $50,000+ because they require a foundation, roof, and weatherproof siding.

What is the best wood for a sauna?

We recommend Western Red Cedar. It smells great, resists rot naturally, and stays cool enough to sit on. For a modern look without the “knots,” we use Clear Hemlock or thermally modified Ash.
