40 Nano Banana Prompts for Interior Design (2026)

40 tested Nano Banana prompts for interior design, organized by space: living rooms, bedrooms, kitchens, bathrooms, home offices, before-and-after renovation shots, and a new section of image-to-image prompts that edit a real photo of a real room. Every prompt is copy-paste ready with a one-click Copy button, and every image is the real, unedited AI output. Updated August 2026 with the image-to-image library, a Nano Banana Pro section, and a fresh Nano Banana vs ChatGPT vs Midjourney comparison.

Nano Banana is Google’s Gemini image model, and it is particularly good at rooms: geometry, furniture proportions and natural light come out believable when you describe them precisely with the five-part formula below. It also does something most people still miss: you can upload a photo of your own room and edit it with a text instruction, which is what the image-to-image section covers. Looking for buildings instead of rooms? Exteriors, facades, aerials and sketch-to-render workflows live in our separate guide of 40 Nano Banana architecture prompts, and for listing photos the Nano Banana real estate prompts.

Nano Banana vs ChatGPT vs Midjourney

Bottom line: Nano Banana wins on realism, speed, and photo editing for interior design. Midjourney wins on artistic style and dramatic composition. ChatGPT wins on conversational iteration. Nano Banana can edit a photo of your actual room, and the image-to-image section below shows exactly how. What none of them do is hold your exact dimensions reliably across edits or connect the render to furniture you can buy. For that part of the job, use a dedicated tool like MeltFlex that preserves your room dimensions and shows purchasable furniture from IKEA, Wayfair, and Amazon.

Nano Banana vs Nano Banana Pro: Which One for Rooms?

Since Nano Banana Pro (Google’s Gemini 3 Pro Image model) reached general availability, every prompt in this guide runs on either tier. The practical differences for interior work:

• Resolution. Standard Nano Banana outputs roughly 1K to 2K images, plenty for screens, mood boards and client decks. Pro renders up to native 4K, which matters for large-format printing and portfolio work.
• Reference images. Pro accepts up to 8 reference images in one prompt. That is what makes “place this exact sofa in this exact room” possible: one photo of the room, one of the sofa, one instruction.
• Localized edits. Both models edit photos, but Pro is noticeably better at changing one region while leaving the rest untouched: repaint one wall, swap one cabinet front, keep everything else pixel-faithful.
• Cost and access. Standard Nano Banana is part of the free Gemini tier with daily limits. Pro generations draw from paid Google AI plans, and via the API a Pro image runs about $0.13 at 1K or 2K and $0.24 at 4K.

Our honest recommendation: start on the standard model. For text-to-image room concepts, the quality gap is small and the formula below matters far more than the model tier. Step up to Pro when you need 4K output, multi-image references, or surgical edits of a real photo.

The Nano Banana Interior Design Prompt Formula

Every high-quality Nano Banana interior design prompt follows the same five-part structure. Master this formula and you can generate professional-grade concepts for any room, any style.

What details to include in your Nano Banana prompt

1. Room type and camera angle. Start with what the image shows: “Wide-angle photograph of a living room, shot from the corner at eye level.” This sets the composition and perspective.

2. Design style in specific terms. Not just “modern” but “warm Scandinavian with Japandi influences.” Layer two style references for more interesting results. The AI responds better to style combinations than single labels.

3. Materials and colors. Name exact materials: “walnut wood console, linen upholstery in oatmeal, brushed brass hardware.” The more specific you are, the more controlled the output. “Walnut console” produces a completely different result than “wooden console.”

4. Lighting. “Soft natural light from large windows on the right, warm pendant lamp overhead, no harsh shadows.” Lighting makes or breaks interior renders. Always specify direction, warmth, and source.

5. Mood or atmosphere word. End with one word that sets the feeling: “serene,” “cozy,” “editorial,” “lived-in.” This final word nudges the AI toward a specific visual temperature and is more powerful than most people realize.

These five elements work for every room type. The sections below use this exact formula for living rooms, bedrooms, kitchens, bathrooms, and home offices.

Nano Banana Kitchen Prompts (17 to 22)

Kitchen prompts need more technical specificity than other rooms. Countertop materials, cabinet finishes, hardware, backsplash details, and appliance placement all matter. Nano Banana handles kitchen geometry well when you specify the layout type (galley, L-shaped, U-shaped, island).

Prompt 17: Modern White Kitchen With Wood Accents

CopyProfessional interior photograph of a modern kitchen with L-shaped layout. White flat-panel cabinetry with brass pull handles. Calacatta marble countertops with subtle grey veining.

Prompt 22: Kitchen Prompt Best Practices

Kitchen prompts fail most often because people forget to specify the layout. “Modern kitchen” can produce anything from a galley to an island kitchen. Always state the layout: galley, L-shaped, U-shaped, or island. Then specify counter material, cabinet style, and hardware. These three elements define 80% of the kitchen look.

Kitchen prompt template:

Copy[Camera angle] photograph of a [layout type] kitchen. [Cabinet description: color, door style, hardware]. [Countertop material]. [Backsplash material and pattern]. [Island or dining detail if applicable]. [Appliance finish]. [Flooring]. [Lighting description]. [One styling detail: herbs, cookbook, fruit bowl]. [Mood word].

Nano Banana Bathroom Prompts (23 to 26)

Bathroom prompts benefit from specifying tile patterns, fixture finishes (matte black, brushed nickel, brushed gold), and whether the space is wet-room style or has a separate shower enclosure. Always mention the vanity style and mirror shape.

Nano Banana Home Office Prompts (27 to 29)

Home office prompts need to balance aesthetics with functionality. Always specify the desk type (floating, standing, L-shaped), chair style, and monitor setup. Lighting matters more in offices because it affects how the AI renders the screen and desk surface.

Prompt 27: Warm Professional Home Office

CopyInterior photograph of a professional home office. Warm white walls. Large walnut desk with clean lines positioned facing a window. High-end ergonomic mesh chair in dark grey. Single ultrawide monitor on a walnut monitor stand. Wireless keyboard and mouse on a felt desk pad. Walnut bookshelf on the adjacent wall with neatly arranged books, one small plant, and a ceramic sculpture. Brass desk lamp with adjustable arm. Cork pinboard on the wall with minimal notes. Oak hardwood floor with a small wool rug under the desk. Natural light from the window plus warm desk lamp. Focused and sophisticated.

Matching brass desk accessories. Light oak floors. Two pendant lights above each workstation. Soft natural light plus task lighting. Collaborative and organized.

Result: symmetrical dual workspace with shared storage

Before and After Renovation Prompts (30 to 31)

These prompts are for interior designers and property developers who want to visualize how a space will look after renovation. The key principle: describe the finished room as if the construction never existed. Do not reference the construction in the prompt. Nano Banana generates from imagination, not from reality.

Prompt 30: Construction Room to Finished Living Room

Starting point: a room during construction

CopyProfessional interior photograph of a newly renovated living room in a modern apartment. Freshly plastered walls in warm white. New oak hardwood flooring. Walnut TV console on the main wall with integrated cable management. Low-profile linen sofa in warm grey. Round oak coffee table. Indoor plants in ceramic pots. Recessed downlights and one pendant lamp. Floor-to-ceiling windows with new aluminum frames and sheer curtains. The room looks freshly completed, clean, modern, ready to live in. Warm and aspirational.

The same room imagined as a finished living space

Prompt 31: Empty Room to Furnished Bedroom

Starting point: empty room with finished walls, no furniture

CopyInterior photograph of a fully furnished master bedroom in a modern apartment. Warm beige walls. King bed centered on the main wall with an upholstered linen headboard in warm grey. White linen bedding with a folded camel cashmere throw. Walnut bedside tables with ceramic lamps. Large round mirror above a low walnut dresser on the opposite wall. Built-in wardrobe with smooth white sliding doors. Sheer white curtains on large windows. Plush cream wool rug. Soft morning light. Peaceful and complete.

The same empty room imagined as a furnished master bedroom

Image-to-Image Prompts: Edit a Real Room Photo (32 to 40)

This is the part most guides skip, and it is the thing Nano Banana is actually famous for: you do not have to generate imaginary rooms. Upload a photo of a real room into Gemini, type an edit instruction, and the model changes what you asked for while keeping the rest of the photo. To prove it, prompts 32 to 36 all edit the same real photo: a lived-in family living room with scuffed walls, a laundry pile and toys everywhere. No staging, no cheating.

The starting photo for prompts 32 to 36: a real, cluttered living room

Image-to-image prompts follow a different formula than text-to-image. You are not describing a whole room; you are locking what stays and naming what changes. Three rules: (1) start by telling the model to keep the camera position, the room proportions, and the windows; (2) name only the changes you want; (3) if you want a partial edit, say “change ONLY” and then explicitly list what must stay. The prompts below show all three moves.

Prompt 32: Full Restyle, Same Room (Japandi)

CopyThis is a photo edit of the exact living room in the photo. Keep the camera position, the room proportions, the window on the left with the plants on the sill, the radiator below it, the wall-mounted TV position and the hardwood floor direction. Redesign it in warm Japandi style: low light-oak platform sofa with oatmeal linen cushions instead of the grey sectional, round light oak coffee table, oak media console under the TV, walls repaired and repainted warm white, jute rug, one ceramic floor vase with a dried branch, paper floor lamp in the corner. All the clutter, toys, laundry and cables gone. Photorealistic, natural daylight, no people, no text.

Result: full Japandi restyle, same window, same TV wall, same radiator

Prompt 33: Change Only the Wall Color

CopyThis is a photo edit of the exact living room in the photo. Change ONLY the walls: repaint every wall in muted sage green with a smooth, freshly painted matte finish, repairing all the scuffs and marks. Keep every piece of furniture, the sofa, the coffee table, the TV unit, the rug, the toys on the floor and all objects exactly as they are. Do not change the floor, ceiling, window or lighting.

Result: sage green walls, and the model kept every toy and the laundry pile exactly in place

Prompt 34: Declutter and Stage for a Listing

CopyThis is a photo edit of the exact living room in the photo. Prepare it for a real estate listing photo: remove the laundry pile, the toys on the rug, the papers and mugs on the coffee table, and every loose cable. Keep the same sofa but neatly styled with two matching cushions and a folded throw, keep the same coffee table with a single small plant, keep the same TV and TV unit with nothing on top. Repair and repaint the scuffed walls in the same warm off-white. Everything else stays identical. Photorealistic, no people, no text.

Result: listing-ready in one prompt, same furniture, clutter gone

Prompt 35: Swap One Piece of Furniture

CopyThis is a photo edit of the exact living room in the photo. Change ONLY the sofa: replace the grey fabric sectional with a cognac brown leather three-seat sofa with track arms and visible patina, positioned exactly where the sectional stands now. Keep the coffee table, the TV and TV unit, the rug, the wall colour and every other object exactly as they are.

Result: one sofa swapped, everything else untouched, which is exactly how you audition furniture

Prompt 36: Change the Time of Day

CopyThis is a photo edit of the exact living room in the photo. Keep the furniture layout but tidy the room: clutter, toys and laundry gone, cables managed. Change the time of day to evening: the window shows dusk outside, the room is lit only by a warm brass floor lamp beside the sofa and a small table lamp on the TV unit, soft pools of warm 2700K light, gentle shadows, cosy and calm.

Result: same room at dusk, lit by two warm lamps the model added on request

Prompt 37: Virtually Stage an Empty Room

Starting point for prompt 37: a real empty apartment

CopyThis is a photo edit of the exact empty apartment room in the photo. Keep the camera position, the room proportions, the balcony doors and window wall, the radiator, the hallway on the left and the light oak floor. Virtually stage it as a Scandinavian living room: light grey linen three-seat sofa on a woven jute rug, round light oak coffee table, oak sideboard with a framed abstract print above it, floor lamp with a linen shade, one olive tree in a terracotta pot near the balcony doors, sheer white curtains. Furniture scaled correctly for the room. Photorealistic, no people, no text.

Result: the same apartment staged, with the balcony wall and radiator kept

One honest caveat before you stage listings this way: several US markets now require AI-staged photos to be disclosed. Our guide to virtual staging disclosure rules covers where and how.

Prompt 38: Change Only the Floor

CopyThis is a photo edit of the exact room in the photo. Change ONLY the floor: replace the current flooring with wide-plank European oak in a herringbone pattern, natural matte finish. Keep every piece of furniture in its exact position, the walls, the ceiling, the window and the lighting unchanged. The new floor must follow the same perspective as the original.

Prompt 39: Place a Specific Product in Your Room (Pro)

CopyImage 1 is my living room. Image 2 is a sofa I am considering buying. Edit image 1: replace my current sofa with the exact sofa from image 2, same colour, same shape, same legs, scaled correctly for the space and positioned where my current sofa stands. Keep everything else in my room exactly as it is. Photorealistic, natural light.

This one needs Nano Banana Pro, which accepts multiple reference images in a single prompt. It is the closest a general image model gets to try-before-you-buy. If you want the same result with furniture that comes with a live price and a buy link, that workflow is native in MeltFlex, where reference pieces come from real IKEA, Wayfair and Amazon catalogs.

Prompt 40: Fix a Listing Photo Without Redesigning It

CopyThis is a photo edit of the exact room in the photo. Do not redesign anything and do not move or replace any furniture. Only correct the photography: straighten the vertical lines, brighten the exposure as if shot with proper HDR, recover the blown-out window so the view outside is visible, neutralize the yellow colour cast, and sharpen slightly. The room itself must remain completely truthful to the original.

Correction-only edits like this are the safe zone for real estate, because nothing about the property is misrepresented. The line between correcting and transforming, and why it matters legally, is the subject of our AI real estate photo editing guide.

Image-to-Image Prompt Template

CopyThis is a photo edit of the exact [room type] in the photo. Keep the camera position, the room proportions, [the windows / doors / built-ins that must not move]. Change [ONLY if partial] [the specific changes: furniture, wall colour, floor, lighting, styling]. Keep [everything that must stay] exactly as it is. Photorealistic, [lighting], no people, no text.

Weighing it against ByteDance’s model? Nano Banana Pro renders native 4K while Seedream 5.0 Pro caps at 2K, but Seedream is roughly half the price and edits more precisely. TheSeedream prompt library has the full comparison and 44 prompts including image-to-image restyling.

When to Use Nano Banana vs a Dedicated Room Tool

As the image-to-image section shows, Nano Banana absolutely can edit a photo of your real room, and for one-off edits it is excellent. The honest limits show up when you use it for an actual furnishing project: each edit is a fresh roll of the dice on geometry, so across a series of iterations walls drift, windows resize, and proportions wander. The furniture it invents is also generic: that beautiful oak sideboard does not exist in any store, so you cannot buy the room it just showed you.

Use Nano Banana when: you need concept inspiration, mood board imagery, style exploration, quick one-shot edits of a room photo, client presentation concepts, or social media content. It is the fastest way to go from an idea to a photorealistic image.

Use a dedicated room tool when: you are iterating on one real room and need the space to stay dimensionally truthful across every version, or when the design has to end in a shopping list. MeltFlex is built for that lane: it holds your exact dimensions, windows, and layout across redesigns and furnishes with real pieces from IKEA, Wayfair, and Amazon that you can actually buy.

8 Advanced Tips for Better Nano Banana Interior Prompts

1. Add negative instructions

Tell Nano Banana what you do NOT want: “No people, no text, no watermarks, no cluttered surfaces, no visible outlets or switches.” Negative instructions prevent the most common artifacts that ruin otherwise good interior renders.

2. Specify camera lens

“Shot on 24mm wide-angle lens” gives you a full room view. “Shot on 50mm lens” gives a tighter, more editorial composition. “Shot on 35mm lens at eye level” is the sweet spot for realistic interior photography. Specifying the lens dramatically improves composition quality.

3. Name real design references

“In the style of an Axel Vervoordt interior” or “similar to a Japandi room featured in Kinfolk magazine” gives Nano Banana a concrete visual target. Named references work better than abstract style descriptions because the model has seen those exact references in its training data.

4. Control lighting with time of day

“Soft morning light” produces cool, gentle illumination. “Golden hour afternoon light” produces warm, dramatic shadows. “Overcast diffused daylight” produces even, shadow-free lighting ideal for showing furniture details. Always specify the time of day rather than just saying “natural light.”

5. Use texture words for monochrome palettes

When your color palette is narrow (all beige, all cream, all white), the AI needs texture descriptors to create visual depth. Not “beige sofa” but “beige linen sofa.” Not “wooden table” but “live-edge walnut table.” Best texture words: linen, bouclé, wool, jute, travertine, limewash, brushed brass, matte ceramic, raw oak, woven rattan.

6. Iterate by changing one element at a time

Once you have a prompt that works, copy it and change only one element: the sofa color, the wall color, or the floor material. This produces a coherent series of design variations from a single prompt, exactly what clients want to see during a design presentation.

7. State room dimensions for small spaces

Adding “approximately 10 square meters” or “approximately 4 square meters” forces Nano Banana to generate appropriately scaled furniture and tighter compositions. Without this, the AI defaults to generous room sizes that do not match most real apartments.

8. Edit, do not regenerate

When a render is 90 percent right, do not reroll the whole prompt and hope. Send the image back as input with a single instruction: “Change ONLY the rug to a vintage kilim in rust tones, keep everything else identical.” Rerolling throws away the 90 percent you liked; editing keeps it. This is the same lock-and-change formula from the image-to-image section, applied to Nano Banana’s own output instead of a photo.
