Mont Alpi Built-Ins

The Built-Ins are the Mont Alpi grill chassis designed for permanent installation in masonry or cabinetry-built outdoor kitchens. Where the modular Original, Black, and Deluxe Series are fully-assembled freestanding islands that ship complete and can be relocated, the Built-Ins are the same Mont Alpi grill engine engineered to drop into a custom outdoor-kitchen build. The line covers a 4-burner unit (MAIB400) and a 6-burner unit (MAIB805), each available in stainless steel and black stainless finishes. Both feature ceramic infrared rear burners and 304 stainless steel construction. Sold and serviced through Seven Seas Pools & Spas.

Burner counts: 4-burner (MAIB400) and 6-burner (MAIB805)
Finishes: Stainless steel and black stainless, both burner counts available in either finish (-bss suffix denotes black stainless)
Construction: All 304 stainless steel components with ceramic infrared rear burners
Distribution: Sold and serviced through Seven Seas Pools & Spas

Who the Built-Ins Are Built For

The Built-Ins are the right line if your outdoor-kitchen project is architectural, a permanent build with masonry walls, cabinetry, or fixed-frame construction, rather than a modular freestanding island.

Built-Ins fit you if you:

Are building a custom outdoor kitchen from masonry, stone, brick, or cabinetry, and need a grill chassis to drop into the build, not a complete island
Are working with a contractor, architect, or outdoor-living designer on a fixed installation
Want the Mont Alpi grill engine and finish quality, 304 stainless steel, ceramic infrared rear burner, and dual-fuel capability, inside your own custom surround
Need to choose between stainless and black stainless to match the rest of the kitchen build's metalwork
Are at the planning stage of a build and can specify gas, electrical, ventilation, and clearances around a known chassis footprint

It is not the right line if you:

Want a fully-assembled freestanding island that ships ready to use, see the Original Series, Black Series, or Deluxe Series
Are not building a custom surround and want the fastest path to outdoor cooking, the modular series ships and sets up without contractor work
Have a small patio or balcony without space for a full custom kitchen, see Small Outdoor Islands for compact pre-built alternatives
Want integrated kamado capability in the chassis, the Built-Ins are gas-fired grilling chassis only; kamado in a custom build comes via a standalone Specialty Module

Planning a custom outdoor kitchen?

Bring your project plans to Seven Seas Pools & Spas before ordering so the chassis, cutout dimensions, gas, electrical, ventilation, and finish choices match the build.

What's in the Built-Ins Lineup

The line is structured around two burner counts and two finishes, with feature variants on each base:

MAIB400 built-in grill chassis — MAIB400

4-burner stainless steel, the compact built-in chassis for smaller custom-kitchen builds

MAIB400-BSS built-in grill chassis — MAIB400-BSS

4-burner black stainless, the same chassis in black-stainless finish

MAIB400-BSS-HRFNM built-in grill chassis — MAIB400-BSS-HRFNM

4-burner black stainless feature variant

MAIB805 built-in grill chassis — MAIB805

6-burner stainless steel, the larger built-in chassis for full-size custom kitchens

MAIB805-BSS built-in grill chassis — MAIB805-BSS

6-burner black stainless

MAIB805-BSS-S2CRA built-in grill chassis — MAIB805-BSS-S2CRA

6-burner black stainless feature variant

All variants share the 304 stainless steel construction and ceramic infrared rear burner. Specific cutout dimensions, BTU ratings, gas fittings, electrical service requirements, and ventilation clearances vary by model, these are supplied with each individual product specification and should be confirmed before drawing the surround. Bring the project plans, or a contractor, to a Seven Seas showroom before ordering so the dimensions can be matched to the kitchen build.

Ready to match a chassis to your plans?

Built-in chassis selection touches gas, electrical, ventilation, and architectural detailing. Call ahead or stop by your local showroom to see the MAIB400 and MAIB805 chassis, confirm cutout dimensions, and review current stainless and black-stainless availability before ordering.

How the Built-Ins Compare to the Modular Series

Feature	Built-Ins	Original / Black / Deluxe Series
Form factor	Drop-in chassis	Fully-assembled freestanding island
Outdoor-kitchen surround	Built by you or your contractor in masonry, cabinetry, or custom architecture	Included, Mont Alpi delivers the complete island
Setup	Contractor installation into a custom build	Delivered fully-assembled, set up by homeowner or delivery crew
Movability	Permanent, part of the structure	Modular and portable, can be uninstalled and moved
Add-on modules	Pair with Specialty Modules in the same custom build	Snap on directly to the modular island chassis
Best for	Architectural outdoor-kitchen projects with a contractor	Households who want a centerpiece without a custom build

If you're torn between the two paths, the Mont Alpi modular series offers most of what custom builds offer, multi-module configurations, premium finish, premium granite, lifetime-warranty chassis, integrated beverage/kegerator/kamado options, with no contractor required. The Built-Ins are the right call only when the rest of the kitchen is genuinely custom-architectural.
