Real Wood Fire, Fan-Assisted Heat — The WPPO Lava 40 Fits Where the 48 Won't
The right-sized Pro-Series wood-fired oven for a serious outdoor kitchen without the 48-inch footprint.
All the wood-fired flavor and fan-assisted heat control of WPPO's Pro-Series Lava Line, in a footprint that works for more outdoor spaces. The Lava 40's convection fan circulates heat throughout the oven chamber so you're cooking evenly instead of chasing hot spots, and the cut and polished volcanic stone floor — actual LAVA, not ceramic — holds and radiates heat the way no substitute can. Thermal guard insulation plus a thick fire blanket keep that heat locked in through the full cook, whether you're running one pizza or feeding a crowd. At 42" wide by 42" deep and 58" tall with the black stand already included, it arrives ready to anchor your outdoor kitchen and start turning out the kind of food that brings people back.
What Makes the Lava 40 Different
Five things that separate a professional wood-fired oven from everything else in the backyard.

Fan-Assisted
Convection Heat
A dedicated convection fan circulates heat evenly throughout the chamber — less rotating dishes, more consistent results every cook.
True LAVA
Volcanic Stone Floor
Cut and polished volcanic stone — not ceramic, not composite. Authentic high-heat performance from the ground up.
Dual-Layer
Thermal Insulation
Thermal guard insulation plus a thick fire blanket work together to lock heat in — so performance holds steady through long cooks and big gatherings.
Mosaic
Pro-Series Shell
The mosaic outer shell is a head-turner before you even light a fire — built to anchor an outdoor kitchen, not just sit in the corner of a patio.
42″ × 42″
Stand Included
At 42" W × 42" L × 58" H with the black stand included, this arrives as a complete elevated setup — no separate base purchase needed.

Deep Dive — Convection Fan & LAVA Stone Performance
›
Digital Wood-Fired Cooking with Convection Fan Performance
The WPPO Lava 40 uses a convection fan to circulate heat evenly throughout the oven chamber. This helps reduce inconsistent cooking and supports a healthier fire, allowing you to prepare wood-fired meals with greater confidence and control.
Volcanic Stone LAVA Cooking Surface
The cooking surface is made from cut and polished volcanic stone, also known as LAVA. This signature Lava Series surface supports authentic wood-fired cooking while giving the oven a distinctive construction profile built around heat, durability, and performance.
Thermal Guard Insulation and Thick Fire Blanket
Thermal guard insulation and a thick fire blanket help the Lava 40 retain heat during cooking. This insulation system supports consistent oven performance, making it easier to maintain strong cooking conditions for gatherings, family meals, and outdoor entertaining.
Mosaic Outer Shell with Black Stand Included
The Pro-Series Lava Line stands out with a stunning mosaic outer shell that adds elegance and sophistication to your outdoor cooking area. The included black stand completes the setup, helping the Lava 40 become a true centerpiece and conversation starter in your outdoor space.
Who It's For — The Deck & Den Take
›
The Lava 40 is the one to pick if you want everything the Pro-Series offers but your space — or your budget — isn't built for the 48. At 42" × 42", it still makes a real statement in an outdoor kitchen, and the cooking experience is identical: fan-assisted heat distribution, volcanic stone floor, dual-layer insulation.
The convection fan is genuinely the thing that makes this oven different from a standard wood-fired setup. It does the heat management work for you, so you spend more time with the people you're cooking for and less time babysitting the fire. That's worth calling out if you're comparing this to a traditional passive oven at a similar price.
Who might want to look elsewhere: if you're regularly cooking for very large groups and space isn't a constraint, the Lava 48 gives you more room to work. But for most home outdoor kitchens, the 40 is plenty — and it's a significantly more approachable price.
- Outdoor entertainers who want Pro-Series performance in a more compact footprint
- Wood-fired cooking enthusiasts looking for modern heat control without giving up authentic flavor
- Homeowners building or upgrading an outdoor kitchen where the 48" model is too large
- Anyone comparing this to the Lava 48 and weighing size vs. budget
- Cooks who want even heat results without constant hands-on fire management

Frequently Asked Questions
›
What are the outer dimensions of the WPPO Lava 40?›
The Lava 40 measures 42" W x 42" L x 58" H overall. These dimensions include the black stand, which is included with the oven.
Is the black stand included, or do I need to buy it separately?›
The black stand is included. The Lava 40 arrives as a complete elevated setup — no separate base purchase required.
What fuel does the WPPO Lava 40 use?›
The Lava 40 is a wood-fired oven. It uses wood as its heat source, which produces the authentic wood-fired flavor the Pro-Series Lava Line is known for. WPPO advises against using driftwood, coal, plywood, or any wood with a binder that burns at excessively high temperatures, as these can damage the oven and void the warranty.
What is the cooking surface made of?›
The cooking floor is cut and polished volcanic stone — also called LAVA. It's not ceramic or composite. This is the signature material of WPPO's Lava Series and supports authentic high-heat wood-fired cooking.
What does the convection fan actually do?›
The convection fan circulates heat throughout the oven chamber, helping reduce uneven hot spots across the cooking surface. It also supports consistent heat maintenance and makes it easier to reignite the flame when needed — so you spend less time managing the fire and more time cooking.
What materials is the WPPO Lava 40 built from?›
The Lava 40 is constructed from volcanic stone, refractory cement, 304 stainless steel, a thick steel inner shell, mosaic tile, and lava rock aggregate. These materials are chosen for heat retention, durability, and the distinctive look of the Pro-Series.
How does the insulation system work?›
The Lava 40 uses a two-layer insulation system: thermal guard insulation plus a thick fire blanket. Together these help the oven retain heat during long cooks and large gatherings, supporting consistent cooking conditions throughout the session.
What is the SKU or model number for the WPPO Lava 40?›
The model number is WKPM-D100. Use this when contacting Deck & Den or WPPO for parts, warranty service, or accessories.
What's the difference between the WPPO Lava 40 and the Lava 48?›
Both ovens are part of the same Pro-Series Lava Line and share the same core technology: convection fan heat distribution, volcanic LAVA stone cooking surface, and dual-layer thermal insulation. The key differences are size and footprint. The Lava 40 measures 42" W × 42" L × 58" H; the Lava 48 measures 48" W × 48" L × 62" H. If your outdoor kitchen has the space and budget for the larger model, the 48 gives you more cooking room. For most home setups, the Lava 40 is the right fit.
What does WPPO's warranty cover on the Lava 40?›
The Lava 40 is covered by WPPO's 1-year warranty from the date of shipment, honored directly by WPPO. Coverage includes the oven's body, floor, ventilation, finishes, stand, door, internal dome welding, and accessories against manufacturing defects or defects in materials.
