Quick Answer: Pit Boss doesn’t sell a pizza oven or a pizza attachment — the only pizza product on pitboss-grills.com is the 15-inch Ceramic Pizza Stone (model 70137, $29.99 direct), a flat stone rated for use in whatever grill, oven, or microwave you already own. It doesn’t add heat the way Green Mountain Grills’ own GMG-4023 attachment does (which pushes past 800°F, per Green Mountain Grills’ own spec page) — a Pit Boss pellet grill on its own tops out around 500°F, short of the 700-900°F range the AVPN (Associazione Verace Pizza Napoletana) sets for true Neapolitan pizza. If you want a Pit Boss to actually reach that heat, a third-party attachment like Stanbroil or Pellethead, not the Pit Boss stone, is the real answer.

Why this search doesn’t have the answer people expect

Pit Boss is one of the biggest names in pellet grills, so “Pit Boss pizza oven” is a natural search — but a check of pitboss-grills.com’s full catalog turns up zero dedicated pizza ovens and, unlike Green Mountain Grills, no official heat-boosting pizza attachment either. What Pit Boss actually sells is the 15-inch Ceramic Pizza Stone, a $29.99 accessory that’s explicitly described as safe for “grills, ovens, or microwaves” — language that only makes sense for a stone that doesn’t change what temperature those appliances reach in the first place.

What you actually get

Pit Boss 15" Ceramic Pizza Stone (Model 70137)

Flat stone for grills, ovens, or microwaves · $29.99 direct
  • 15-inch ceramic stone with built-in lift handles, rated for grills, conventional ovens, or a microwave — not a pellet-grill-specific product.
  • Non-stick surface that develops with use; hand wash only, no seasoning required per Pit Boss's own care instructions.
  • Does not raise your grill's maximum temperature — it's a cooking surface, not a heat-trapping chamber like a true pizza attachment.

For anyone who actually wants pizzeria-style heat on a Pit Boss grill, the stone alone won’t get you there — you need something that traps and redirects the firebox heat, which is exactly what third-party attachments are built for.

Pit Boss stone vs. the attachments that actually add heat

Pit Boss 15" Ceramic Pizza StonePit BossNo — grate/oven ceiling only~450-500°F$29.99

The honest read: Pit Boss’s own pizza product and Green Mountain Grills’ own pizza product solve completely different problems, even though both are the “official” accessory from a pellet-grill maker. GMG’s attachment is a real heat-boosting chamber; Pit Boss’s stone is just a stone. If you own a Pit Boss and want GMG-style results, a third-party attachment — not anything Pit Boss itself sells — is the only route.

Who should actually buy this

The bottom line

There’s no such thing as a “Pit Boss pizza oven” to buy — the honest answer is a $29.99 ceramic stone that doesn’t change what temperature your grill reaches. If a flat stone at your grill’s existing heat is enough, it’s a cheap, well-reviewed accessory. If the goal is real 600-800°F pizzeria heat, skip the Pit Boss stone and go straight to a third-party attachment like Stanbroil or Pellethead, both of which explicitly list Pit Boss compatibility, or a dedicated standalone oven that doesn’t depend on your grill at all.
