WPPO Karma 32" Professional Wood-Fired Oven – 304 Stainless Steel Outdoor Cooking
Three pizzas at once, up to 900°F, and a fire brick floor that holds heat like a wood-fired oven should.
Most backyard pizza ovens make you choose between capacity and heat — the WPPO Karma 32 doesn't. Its 1.25" cordierite fire brick floor cranks to 900°F and stays there, pulling moisture out of the dough just fast enough to give you that blistered, leopard-spotted crust you'd pay $25 a pizza for at a restaurant. The R3 interior radiates, reflects, and retains heat so you're not burning through a cord of wood to get there. At 729 square inches of cooking surface, you're running three pizzas at once or going back and forth between a cast iron and a pie — all in full view of whoever's gathered around outside. Built from 304 stainless steel inside and out, this one's meant to live in your outdoor kitchen, not a garage.

Who It's For — The Deck & Den Take
▸
The Deck & Den Take
The Karma 32 is for the person who wants a serious wood-fired oven without building a permanent dome into their outdoor kitchen. It's stainless throughout, sits flat on a countertop or drops into a built-in setup, and it's big enough that you're actually cooking for a crowd — not just showing off for one.
If your outdoor kitchen already has a stainless aesthetic, this fits right in. If you've been eyeing one of those portable backyard pizza ovens, this is a significant step up — more cooking surface, more heat, and a fire brick floor that stays hot between pies instead of cooling down on you mid-party.
One tip most buyers don't ask about: budget for the stand if you don't have a countertop or island to set it on. The oven-only height (41.75") is too low to cook standing up comfortably. The optional Karma 32 cart adds the right height and gives you casters so you can move it. Not a dealbreaker, just plan for it.
-
Outdoor kitchen owners who want a built-in or countertop wood-fired oven that matches their stainless appliances.
-
Backyard entertainers who cook for groups — three-pizza capacity means you're not making guests wait.
-
Wood-fired cooking enthusiasts who want a real fire brick floor and proper R3 heat retention, not just a metal box with a door.
-
Cooks who want versatility — cast iron pans, bread, roasts, and whole proteins all work alongside pizza in the same cook session.
-
May not be the right fit if you need something portable or don't have an existing surface or plan to add the stand — this is a countertop/built-in oven first.

Frequently Asked Questions
▸
What are the overall dimensions of the WPPO Karma 32?▸
The oven body measures 35" L x 33.75" W x 41.75" H. The interior cooking area is 27" deep x 27" wide x 10.5" tall, giving you 729 square inches of cooking surface.
What is the maximum temperature of the Karma 32?▸
The Karma 32 reaches up to 900°F — hot enough for true Neapolitan-style pizza with a blistered crust in under two minutes when the oven is fully preheated.
How many pizzas can I cook at once?▸
The Karma 32 accommodates up to three pizzas at a time, or you can use the space for a mix of cast iron pans and one or two pizzas simultaneously.
What type of fuel does the Karma 32 use?▸
The Karma 32 is a wood-fired oven that runs on hardwood only. There is no gas conversion option for this model.
What's the cooking floor material — is it a real baking stone?▸
Yes. The Karma 32 includes a 1.25" cordierite ceramic fire brick floor — the same type of material used in professional pizza ovens. It retains heat between cooks and keeps the deck temperature steady across multiple pies.
Can I cook things other than pizza in the Karma 32?▸
Absolutely. The 729 square inch cooking surface handles cast iron skillets, bread, roasts, whole chickens, and even steaks. Anything you'd cook in a high-heat oven works well here — wood fire just adds a layer of smoke flavor you can't replicate indoors.
Does the Karma 32 come with a stand, or is that separate?▸
The stand is sold separately. The Karma 32 is designed for countertop or built-in installation with leveling legs included. The optional Karma 32 Stand / Cart adds approximately 40" of height and includes casters with wheel locks for mobility.
What is the door opening size on the Karma 32?▸
The door opening measures 15.75" wide x 7.75" tall — sized to accept a standard 12" to 14" pizza peel and most large cast iron pans.
How does the R3 interior work?▸
WPPO's R3 system stands for Radiate, Reflect, and Retain. The double-walled stainless interior lined with woven fire blanket insulation keeps heat cycling back into the cooking chamber rather than escaping through the walls — which means you use less wood to hold temperature and the oven recovers faster between pies.
Can the Karma 32 be installed as a built-in oven?▸
Yes. The Karma 32 is designed for both countertop placement (with the included leveling legs) and built-in installation in an outdoor kitchen surround. Contact us if you need clearance or cutout specifications for your island build.
How much does the Karma 32 weigh?▸
The oven body weighs 179 lbs. You'll need two people to lift and position it. If you need it to be portable, the optional cart with casters makes moving it much easier.
Is the Karma 32 made in the USA?▸
No. The WPPO Karma 32 is not manufactured in the USA.
What warranty does the Karma 32 come with?▸
The Karma 32 is covered by WPPO's 1-year limited warranty from the date of shipment, honored directly by the manufacturer. It covers manufacturing and material defects in the oven body, floor, ventilation, finishes, stand, door, internal dome welding, and accessories. See the owner's manual or contact us for full warranty terms.
Does this ship free, and how does delivery work for a 179 lb. oven?▸
Yes, the Karma 32 ships free via freight to the continental U.S. Freight delivery means a semi-truck with liftgate service — the carrier brings the pallet to the curb. You'll want a plan for moving it from the curb to its final location. Contact us with any questions about your delivery before you order.
