About Our Vault Room Service
A vault room is a purpose-built secure space — fabricated from heavy steel plate, reinforced concrete, and engineered locking systems — designed to protect high-value contents over the long term. Unlike a panic room (focused on personal protection) or a standard safe (limited capacity), a vault room offers walk-in storage for collections, firearms, wine, precious metals, sensitive documents, and irreplaceable assets. We design and fabricate vault rooms ranging from compact 6'×8' steel-lined closets to large bank-grade installations exceeding 500 square feet — often featuring a reclaimed bank vault door as the entry.
Vault rooms appeal to clients whose security and storage needs exceed what an off-the-shelf safe can provide. Collectors of fine wine, watches, art, and firearms install vault rooms to consolidate their holdings in one carefully climate-controlled environment. Cannabis businesses, jewelry retailers, and precious-metal dealers rely on vault rooms to meet insurance underwriting requirements. High-net-worth families across the Bay Area use vault rooms as both a security investment and an architectural feature — paired with a reclaimed bank vault door, a vault room becomes a striking design element.
Global Bunkers has been designing, fabricating, and installing vault rooms since 1988 — more than 36 years of in-house steel plate fabrication and on-site installation experience. We build every vault room to your specifications: structural requirements, security rating, interior layout, lock and access control system, and aesthetic finish. Our team handles the full process from initial design through structural reinforcement, fabrication, transport, and installation — typically completing residential vault rooms in eight to twelve weeks.
We install vault rooms across the Bay Area — including Palo Alto, Atherton, Hillsborough, Woodside, Los Altos Hills, Pacific Heights, Marin County, and Silicon Valley — and statewide across California, from Napa Valley wine cellars to Lake Tahoe and Sierra Nevada estates and Central Coast properties in Monterey, Carmel, and San Luis Obispo. Different markets call for different configurations: Napa and Sonoma projects often pair the vault with climate-controlled wine storage; Atherton, Hillsborough, and Woodside projects frequently emphasize concealment behind library millwork or wine room entries; Silicon Valley projects may integrate biometric and electronic access systems compatible with smart-home platforms. We tailor each vault to the property and the client's specific use case.
What's Included
- Heavy steel plate walls, ceiling, and floor — typically 1/4" to 1/2" depending on rating

- UL-listed vault door — new or reconditioned from our bank liquidation inventory
- Multi-point locking with mechanical combination, electronic keypad, or biometric access
- Climate control and humidity management for wine, watches, art, and document storage
- Custom interior fit-out — shelving, drawers, watch winders, gun racks, wine racking

- Optional alarm integration, motion detection, and remote monitoring
Frequently Asked Questions
What's the difference between a vault room and a panic room?
A vault room is built primarily to protect contents — collections, firearms, wine, documents, precious metals — over the long term. A panic room is built primarily to protect people for a short duration during an emergency. The construction can be similar (reinforced walls, vault-rated door), but vault rooms emphasize storage, climate control, and access management, while panic rooms emphasize life support, communications, and ballistic protection. Many clients install both in the same property.
How much does a custom vault room cost?
Custom vault rooms typically range from $75,000 for a compact steel-lined closet with a basic vault door to $500,000 or more for a large, fully finished walk-in vault with climate control, premium interior fit-out, and a high-security vault door. The main cost drivers are size, security rating, the vault door specification, structural reinforcement requirements, and the interior finish level. We provide a detailed proposal after the site assessment.
Can a vault room be added to an existing home?
Yes. Most of our vault room projects are retrofits into existing residences and commercial buildings across the Bay Area and California. The two key constraints are structural — the floor must support the weight of the steel construction and vault door — and access — getting materials into the build site without disrupting the rest of the property. We handle structural assessment as part of the design phase and propose framing reinforcement when needed.
How long does a vault room take to build?
A standard residential vault room takes eight to twelve weeks from design approval to completion. The fabrication itself takes four to six weeks in our shop; site preparation, structural reinforcement, transport, and installation add another four to six weeks. Larger or more complex builds — bank-grade vaults, multi-zone wine rooms, projects requiring custom millwork — can take three to five months. We provide a detailed timeline during the design phase.
Do vault rooms use bank vault doors?
Often, yes. Reclaimed bank vault doors from our liquidation inventory are a popular choice — they offer bank-grade security at a fraction of the cost of new fabrication, and they make a striking architectural feature. We also install new vault doors from manufacturers when specific ratings or finishes are required. We'll recommend the best option based on your security needs, budget, and the aesthetic intent of the space.
