If you're planning an outdoor kitchen, the pizza oven is the centerpiece — the thing your guests gather around while everything else on the counter goes ignored. But once you start pricing options, you hit a fork in the road fast: a custom masonry oven built brick-by-brick is a major custom project, while a built-in pizza oven kit delivers 900°F+ wood-fired performance without that build. This guide covers how kits work, how to size one correctly, and the models we carry for 2026.
What Is a Built-In Pizza Oven Kit?
A built-in kit (sometimes called a DIY oven kit or drop-in oven) is a pre-engineered refractory oven core — dome, hearth, and flue — that arrives ready to be set into a masonry enclosure or island. Your contractor (or a capable DIYer) builds the surround; the kit handles everything that actually matters for cooking: heat retention, airflow, and a hearth that holds searing temperatures. You get authentic wood-fired results without paying an artisan mason to hand-build a dome.
How to Choose the Right Size
Size is an easy decision to get wrong — usually by going too small. Here's the honest breakdown:
- Cooking for 2–6 people: a compact kit around a 27" (70cm) interior handles one large pizza at a time plus roasts and bread. Ideal for tighter island footprints.
- Cooking for 6–12 people: a mid-size ~39" (100cm) interior lets you run two pizzas side by side, which is the difference between feeding a party and making everyone wait in line.
- Large gatherings or big families: a 47" (120cm) class oven cooks three or more pizzas at once and swallows whole roasts, briskets, and multiple bread loaves.
The Built-In Kits We Carry
1. WPPO Tuscany AD70 — Compact Kit
The Tuscany AD70 ($1,999) is the entry point into true built-in wood-fired cooking. Refractory construction, fast heat-up, and a footprint that fits into modest outdoor kitchen islands. If your gatherings are usually family-sized, this is the smart-money pick.
2. WPPO Tuscany AD100 — Mid-Size Kit
The Tuscany AD100 ($2,749) is the mid-size option. Room for two pizzas at once, serious thermal mass for long roasting and bread sessions after the fire dies down, and proportions that anchor a full outdoor kitchen without dominating it.
3. WPPO Tuscany AD120 — Large-Capacity Kit
The Tuscany AD120 ($3,349) is the large-capacity option: three-plus pizzas at a time for big outdoor kitchen builds. If you host big, or you never want to hear "is mine ready yet?" — this is the one to look at.
What About Venting and Covered Structures?
A question we get a lot: "Can I install this under a roof or in a three-walled outdoor kitchen?" Yes — with proper chimney clearance. Wood-fired ovens need the flue extended above the roofline with adequate clearance from combustible materials, exactly like an indoor fireplace. Plan the venting with your contractor before the enclosure is built, not after. If you're unsure whether your structure works, contact us with a photo of your space and we'll tell you straight. We don't install — your licensed installer/contractor does.
The Real Cost Math
A $2,749 kit plus a contractor-built enclosure gets you a full built-in wood-fired oven without a from-scratch masonry dome. Get a quote on the enclosure from your contractor before you commit.
