Garden Pizza Oven

Choosing a Wood-Fired Pizza Oven for Your Garden

The right garden pizza oven depends on more than maximum cooking temperature. Available outdoor space, cooking capacity, oven shape, supporting base, insulation and frequency of use all influence which model is the better fit.

VITCAS garden ovens range from compact models for home patios to larger refractory ovens suited to outdoor kitchens, restaurants, catering and events. The range includes both formed refractory ovens and traditional brick-built designs, allowing the appearance and scale of the oven to be matched to the intended setting.

Compact Garden Pizza Ovens

Where patio or garden space is limited, a compact oven reduces the required installation footprint while retaining the characteristics of traditional wood-fired cooking. The VITCAS Casa uses a compact arched refractory chamber and can cook approximately one to two small pizzas at a time.

The VITCAS-S provides another compact option but uses a traditional firebrick construction. This makes it particularly suitable where the visual character of a brick pizza oven forms part of the garden or outdoor-kitchen design.

Traditional Dome-Shaped Pizza Ovens

Dome ovens use a curved refractory chamber to absorb heat from the wood fire and radiate it back towards the cooking floor and food. This traditional geometry is widely used for pizza and bread ovens because it combines a heat-storing floor with a refractory chamber surrounding the cooking space.

The VITCAS Pompeii range provides several sizes based on this format. The standard Pompeii Oven suits domestic wood-fired baking, while the larger Pompeii 100, Pompeii 120 and Pompeii 140 provide progressively greater cooking space for larger households and professional applications.

Brick Garden Pizza Ovens

The VITCAS-S and VITCAS-L use refractory firebrick construction to combine the traditional appearance of a masonry oven with pre-formed sections that simplify installation.

The smaller VITCAS-S is suited to more restricted outdoor areas, while the larger VITCAS-L provides additional cooking space for bigger garden kitchens and more frequent entertaining.

Garden Pizza Ovens for Restaurants & Catering

Larger garden ovens are not limited to domestic use. Models such as the Pompeii 100, Pompeii 120, Pompeii 140 and larger brick ovens can suit restaurants, pizzerias, bakeries, hospitality terraces, festivals and catering operations where greater chamber capacity is required.

For professional installations, model selection should consider expected batch size, service pattern, preparation space, fuel storage, access around the oven and the complete flue arrangement rather than chamber size alone.

Pizza, Bread & More from a Wood-Fired Oven

A garden oven can support several styles of cooking because the chamber changes character as the fire develops and then declines. High-temperature firing is suited to rapid pizza cooking, while the heat stored in the refractory mass can also be used for bread, roasting, vegetables, casseroles and slower-cooked dishes.

This makes oven size relevant not only to the number of pizzas that fit on the floor but also to the cookware, bread loaves or roasting dishes intended for regular use.

Supporting a Garden Pizza Oven

A refractory pizza oven is a substantial permanent load and requires a stable, level and non-combustible support. The support must be capable of carrying the complete installed weight, including the oven, insulation, external finish, chimney components and any additional masonry.

The finished height should also be considered before construction. Positioning the oven floor at a practical working level improves access for loading fuel, turning pizzas and handling cookware.

Insulating the Oven Base

Heat that passes downward through an uninsulated oven floor is no longer available for cooking. Suitable insulation beneath the refractory chamber therefore helps separate the hot cooking floor from the supporting structure.

For example, VITCAS recommends 50mm Ceramic Fibre Insulation Board beneath the Casa oven, fully supported as part of the structural base. Base-insulation requirements can vary between oven models, so follow the installation details for the selected oven.

Insulating the Oven Dome or Chamber

External insulation limits heat flow through the oven walls and dome. For compatible VITCAS ovens, a typical system can include Ceramic Fibre Blanket, Ceramic Fibre Adhesive, Pizza Oven Wire Mesh and an exterior refractory render.

The insulation blanket performs the thermal function, the mesh supports the exterior layer and the rendered finish protects the insulated build-up. These layers should be considered as a system rather than treating the external render alone as oven insulation.

Outdoor Oven Cement & Weather Protection

VITCAS Outdoor Oven Cement is a hydraulically setting refractory mortar formulated for exterior high-temperature applications. It is water-insoluble and resistant to rain and frost after setting, making it suitable for compatible outdoor oven construction and finishing.

Outdoor ovens should nevertheless be detailed to limit unnecessary water penetration into refractory masonry and insulation. Weather protection is particularly important where absorbent insulation is enclosed beneath an exterior finish.

Arch Fire Bricks for Custom Oven Details

VITCAS Arch Fire Bricks are tapered refractory bricks measuring approximately 230 × 114 × 54–76mm. Their shape is designed to help form curved refractory structures such as pizza-oven door arches and tunnel-shaped oven roofs.

They are particularly useful where a garden installation includes custom firebrick details around a pre-made oven or forms part of a bespoke masonry oven project.

Heat Resistant Silicone in Pizza Oven Assembly

VITCAS Heat Resistant Silicone is a flexible sealant rated up to 315°C. It is supplied with or used in the assembly of compatible VITCAS oven models where a flexible high-temperature joint is specified.

Its function is different from that of refractory mortar: silicone accommodates movement in suitable joints, while Outdoor Oven Cement is used for compatible rigid refractory jointing and exterior construction.

Planning the Finished Oven Footprint

The dimensions of the refractory oven body are only part of the space required for installation. Allow for base insulation, external blanket insulation, mesh and render, chimney components, the open oven door, working access and nearby preparation areas.

This is especially important when installing an oven close to garden walls, beneath pergolas or within a fitted outdoor kitchen. The completed installation can occupy more space than the nominal oven dimensions suggest.

Chimney Position & Outdoor Installation

A wood-fired oven produces hot combustion gases and requires a suitable flue arrangement. Chimney height, termination position and proximity to roofs, covered structures and neighbouring surfaces should be considered as part of the installation rather than after the oven has been positioned.

Installations beneath a roof, pergola or other covered area may introduce additional building, ventilation and fire-safety requirements. These should comply with the regulations applicable in the country and location of installation.

Choosing the Right Garden Pizza Oven

• Available space: measure the complete installation area, not only the refractory oven body.
• Cooking capacity: consider typical batch size, cookware and how often the oven will be used.
• Oven style: choose between compact formed refractory, traditional firebrick and dome-shaped designs.
• Base: provide stable structural support and the required thermal insulation beneath the oven.
• External insulation: complete the specified blanket, reinforcement and finishing system where required.
• Chimney: plan the complete flue route before fixing the oven position.
• Weather exposure: finish the oven system to protect refractory and insulation layers from unnecessary moisture ingress.

The most useful comparison is therefore not simply small oven versus large oven: it is the complete installed cooking station—oven capacity, insulation, support, chimney, working area and weather protection considered together.

Frequently Asked Questions About Garden Pizza Ovens

Which garden pizza oven is suitable for a small patio?

Compact models such as the VITCAS Casa and VITCAS-S are designed for installations where space is more limited. Measure the finished footprint including insulation, exterior finish, chimney and working access before selecting the oven.

How many pizzas can the VITCAS Casa cook at once?

The Casa can accommodate approximately one to two small pizzas at a time. It is intended primarily for home gardens, patios and compact outdoor kitchens and can also be used for bread, vegetables, roasting and slow-cooked dishes.

Which VITCAS garden oven is suitable for larger batches?

Larger models such as the Double Casa, VITCAS-L and Pompeii 100, 120 and 140 provide increased cooking space. For example, Double Casa can accommodate up to approximately four pizzas, while Pompeii 100 is specified for approximately three to five small pizzas at a time.

What is the difference between a brick oven and a dome-shaped Pompeii oven?

Both use refractory materials to store cooking heat, but their construction and appearance differ. VITCAS-S and VITCAS-L use a traditional firebrick format, while the Pompeii range uses a curved dome-shaped refractory chamber. Available space, capacity and preferred architectural style can therefore influence the choice.

Does a pre-made garden pizza oven still need insulation?

Many pre-made refractory ovens benefit from or specify additional base and external insulation. For the Casa, VITCAS recommends 50mm Ceramic Fibre Board beneath the oven and Ceramic Fibre Blanket around the chamber as part of the external insulation system.

Why is insulation used underneath a pizza oven?

Under-floor insulation reduces heat transfer from the refractory cooking floor into the supporting base. This keeps a greater proportion of the stored heat within the oven system and thermally separates the hot chamber from the structure supporting it.

Can the outside of a garden pizza oven be tiled or painted?

Yes, where the oven system and chosen finish permit it. On the Casa, VITCAS specifies external insulation followed by wire mesh and Outdoor Oven Cement render; compatible decorative paint or tiles can then be used over the completed exterior system.

Can a garden pizza oven be used for bread and roasting?

Yes. Wood-fired ovens can be used for pizza as well as bread, roasting, vegetables, casseroles and other dishes. Different foods make use of different stages of the firing and cooling cycle, from intense live-fire heat to retained refractory heat.

Can a garden pizza oven be installed beneath a covered outdoor area?

A covered installation requires additional consideration of the chimney route, ventilation, nearby combustible materials and local building and fire-safety requirements. These factors should be resolved before the oven position and surrounding outdoor-kitchen construction are finalised.

What should I measure before ordering a garden pizza oven?

Measure the available width and depth, supporting-base area, finished oven height, chimney route and access in front of the oven. Allow extra space for insulation, render or decorative finishes, the open door, fuel handling and comfortable movement around the cooking area.
