Cavestone Fireplace Doors — Custom-Built USA

Cavestone fireplace doors are one of the most popular doors in our catalog — matte-black steel with cabinet-style swing doors, designed for masonry fireplaces where the customer wants an inside-fit installation that looks built-in and modern. Cavestone defaults to Inside Fit with a cabinet (twin-door swing) configuration. The result is a recessed, architectural look that disappears into the fireplace when the doors are open. Most Cavestone installs are Inside Fit on cleanly-built masonry openings.

Why choose Cavestone

  • Built in the USA by Design Specialties (Milwaukee, WI) — one of our trusted manufacturing partners.
  • Custom-sized to your fireplace opening — no standard sizes that almost-fit. Every door is built to your tape-measure dimensions.
  • Precision-built frame — Cavestone is engineered for a clean, tight reveal on square masonry openings.
  • Hand-verified before production. Every order reviewed by our fireplace specialists — your photo, configurator selections, and measurements confirmed before the shop builds anything.
  • Free freight shipping in the continental US, with financing available via Shop Pay.
  • Cavestone is a go-to inside-fit choice for premium masonry installations.

Available fits and configurations

Cavestone is available in Inside Fit (default) and Overlap Fit (available). Cavestone is best for masonry fireplaces with reasonably square openings — variance under 1/4" between top, middle, and bottom widths. Modern and transitional homes love the cabinet-style twin doors for the architectural feel.

Popular sizes: 36" × 30", 42" × 32", 48" × 30". Every door is made to order and ships in a few weeks.

How to measure for Cavestone

The measurement process is the same for every door — measure the FRONT opening of your fireplace at three points (width: top/middle/bottom; height: left/center/right) and use the smallest. See our step-by-step measuring guide for the full walkthrough including how to handle lintel bars, prefab quirks, and rough masonry.

Frequently asked questions

Is Cavestone good for masonry or prefab fireplaces?

Cavestone works best on masonry fireplaces. For prefab, see Brookfield or Rainbow.

What finishes does Cavestone come in?

25 finishes — the same palette Design Specialties uses across its doors and mantels — from included Powder Coat colors (matte black, textured black) through premium plated options (antique brass, brushed nickel, oil rubbed bronze) to handcrafted finishes (forged iron, burnished bronze, burnished copper). Exact pricing for every finish shows live in the configurator.

How long does Cavestone take to ship?

Every Cavestone door is made to order and typically ships in a few weeks. Premium plated and handcrafted finishes can take longer — call (949) 619-7824 for current production times.

Can I order Cavestone with a mesh curtain?

Yes. Choose Twin Gate Mesh (most popular — swing-open like saloon doors), Single Panel Gate, Stainless Steel Mesh (extended lead time), or No Mesh / Glass Only. Mesh sits behind the glass, so you can close glass for energy savings when the fireplace is cold and open glass + close mesh for spark protection during burns.

What's the warranty on Cavestone?

Warranty terms depend on your specific configuration — call us at (949) 619-7824 and our team will walk you through the coverage for your Cavestone order. Every order also includes our Expert Fit Review: measurements verified before production.
