Nano Banana 2 Image-to-Image: Restaurant Furniture Replacement Prompts

Redesigning a restaurant interior often requires visualizing how new seating or table styles will fit within an existing space before purchasing anything. The Nano Banana 2 image-to-image workflow offers a practical solution for this challenge. By uploading a reference photo of your current dining area, you can instruct the tool to replace specific furniture items while strictly maintaining the original architectural lines, camera angle, and lighting conditions. This approach allows designers and owners to experiment with different aesthetics without the cost of physical staging.

It is important to understand that Nano Banana refers to the AI image generation and editing tool in these articles. It is not a skincare brand, bottle, jar, or physical subject. When using the prompt library, users can copy instructions directly into the generator. However, prompt instructions describe desired outcomes; they do not guarantee identity, label, object, or typography preservation. The following examples are designed to help you achieve realistic replacements, but results may vary based on the complexity of the input image.

Preserving Perspective and Lighting During Swaps

The most critical aspect of replacing furniture in a restaurant setting is maintaining the integrity of the room itself. If the AI alters the vanishing point or shifts the light source, the result will look artificial and unusable for planning purposes. To achieve this, your prompt must explicitly prioritize the background elements over the foreground objects being changed.

When crafting your instruction, specify that the walls, floor patterns, ceiling fixtures, and ambient lighting must remain untouched. Focus the replacement command solely on the target furniture pieces. For instance, if you are swapping a wooden booth for a modern leather chair, the prompt should state that the new chair must cast shadows consistent with the existing overhead lights and align perfectly with the floor tiles. This ensures the new furniture feels like it belongs in the scene rather than being pasted on top.

Five Materially Different Prompts for Specific Scenarios

Below are five distinct prompt examples tailored for different restaurant renovation needs. These are examples of how to structure your requests. You can adapt them to your specific reference photos.

1. Modernizing Booth Seating While Keeping Tables

Use Case: Ideal when you want to update the seating style (e.g., from vintage wood to contemporary velvet) without changing the tabletops or layout. Prompt: "Replace all high-back wooden booths with modern low-profile velvet banquettes in navy blue. Keep the existing round oak tables, floor tiles, and wall colors exactly as they are. Maintain the same perspective and lighting direction." Adjustment: If the velvet texture looks too shiny, add "matte finish" to the description.

2. Converting Casual Tables to Fine Dining Setup

Use Case: Useful for transitioning a casual bistro vibe to a more upscale atmosphere by changing table shapes and chair styles. Prompt: "Swap square laminate tables for large rectangular marble-top tables. Replace plastic chairs with gold-framed upholstered dining chairs. Preserve the window views, ceiling beams, and natural sunlight angles. Do not alter the floor pattern." Adjustment: If the marble texture appears too uniform, specify "natural stone veining" in the prompt.

3. Outdoor Patio Furniture Integration

Use Case: Best for restaurants with mixed indoor-outdoor spaces where you need to visualize wicker or metal furniture in a sunlit environment. Prompt: "Replace the current metal benches with woven wicker lounge sets featuring beige cushions. Ensure the shadows match the afternoon sun position coming from the left. Keep the brick pavers and outdoor planters unchanged." Adjustment: If the shadows are incorrect, explicitly mention "cast shadows consistent with the sun position on the left."

4. Bar Counter and Stool Overhaul

Use Case: Perfect for updating the bar area without affecting the surrounding kitchen or service counters. Prompt: "Change the current bar stools to tall industrial-style metal stools with black seats. Replace the standard bar counter with a reclaimed wood surface. Keep the backlit shelves, mirror, and floor tiles identical." Adjustment: If the wood grain looks unnatural, request "distressed reclaimed wood texture."

5. Quick Layout Testing with Minimal Changes

Use Case: A rapid test to see if a single new table fits in a corner without redrawing the entire room. Prompt: "Insert a round glass-top table with a chrome base into the empty corner near the window. Keep all other furniture, walls, and lighting exactly as shown in the original photo." Adjustment: If the table floats, add "place the table legs firmly on the floor tiles."

Selecting the Right Model for Your Workflow

Google documents Nano Banana 2 as Gemini 3.1 Flash Image, Nano Banana Pro as Gemini 3 Pro Image, and Nano Banana 2 Lite as Gemini 3.1 Flash Lite Image. These are distinct Google image models with different capabilities. For complex furniture replacement tasks requiring high fidelity in lighting and perspective, the standard Nano Banana 2 or Nano Banana Pro models are generally preferred.

Google describes Nano Banana 2 Lite as focused on speed and cost. It is not optimized for multiple reference inputs or multi-turn sequential editing. Do not recommend it for those workflows without explaining this limitation. If your project requires iterating on a design or combining multiple reference images to get the perfect furniture fit, the Lite version may struggle to maintain the necessary consistency. Always verify the specific features available on the product page at Try Nano Banana. Remember that the website has a Nano Banana 2 product page at /nanobanana2 and supports text-to-image and image-to-image workflows, but availability of specific model tiers should be confirmed on their respective pages.

By using these structured prompts, you can effectively leverage the Nano Banana 2 tool to visualize restaurant renovations with confidence, ensuring that your new furniture choices harmonize perfectly with your existing space.
