# AI Bathroom Design Generator

> AI bathroom design turns a photo of your own bathroom into a remodel idea — new tiles, vanity, shower, lighting and colours — while the toilet, the shower or tub position, the window and the camera angle stay the same. On Kenerate AI you upload it to Seedream 5.0 Pro, or paint over just the floor or one wall with Change Region to compare two tiles. It shows a look, not a plan: check a new shower or toilet spot against your building code before you buy.

## In depth

### Which Kenerate model should you use for a bathroom?
Each one edits your photo rather than inventing a new room. Credits are per image, read from the app's price code on 21 October 2026.
- Seedream 5.0 Pro — the whole bathroom from one photo, plus Change Region (one wall, the floor, the vanity) and Magic Eraser (towels, bottles, bath mats) in Edit Studio. Up to 10 images. 13.5 credits at 1K or 1.5K, 27 at 2K.
- Nano Banana 2.1 — when it has to be the vanity, tile or shower set you're actually buying, from product photos. Up to 14 images, 1K to 4K. 21 credits at 1K, 31.5 at 2K, 42 at 4K.
- GPT Image 2.5 Sunburst — one precise change and nothing else, like swapping the tub for a walk-in shower. Up to 16 images. 11.7 credits for a medium-quality 1K edit with one photo, plus 4.5 per extra image.
- Qwen Image 3.0 — on the free plan; the default AI Edit model. Up to 3 images. 9.9 credits with one photo.

### Bathroom styles and the words that work
Name the tile, the vanity, the shower and the metal finish — a style word alone gives a hotel-brochure bathroom:
- Spa / warm minimal — “large beige limestone-look porcelain, oak floating vanity, stone basin, walk-in shower with clear glass, warm 2700K light”.
- Modern monochrome — “matte white large-format walls, charcoal floor tile, black frameless shower screen, black fixtures”.
- Japandi wet room — “microcement walls and floor, light oak vanity, open shower with linear drain, paper-shade pendant”.
- Vintage black and white — “white subway tile with a black pencil border, black and white hex floor, pedestal sink, chrome cross-handle taps”.
- Coastal — “soft blue zellige shower wall, white oak vanity, rattan mirror, brushed nickel fixtures”.
- Terrazzo — “white terrazzo floor with grey chips, sage green vertical stack-bond wall tile, white vanity, brass fixtures”.
- Moody — “dark green gloss tile, black marble-look vanity top, brass wall lights, smoked glass screen”.

### Small and windowless bathrooms
Many bathrooms are small, and the room usually can't grow. Ask for changes that make it feel bigger without moving the plumbing: a wall-hung vanity, one large floor tile with few grout lines, vertical wall tile or tile to the ceiling, clear glass instead of a curtain, a recessed niche instead of a shelf, and a big lit mirror.
In a windowless bathroom, say “no window, lit by a ceiling light and mirror lights” in the prompt; image models like daylight and may add a window that isn't there. Check the result for fake windows and skylights before you show it to anyone.

### Will the new layout fit? Check it first
An AI picture never measures. If your idea moves a toilet or enlarges a shower, check the minimums in the International Residential Code (IRC), the model most US states adopt, before you plan around it:
- Toilet: at least 15 inches from its centreline to any side wall, partition or vanity, and at least 21 inches of clear space in front.
- Shower: at least 900 square inches of floor inside, with no side under 30 inches.
- Showerhead: WaterSense-labelled ones use 2.0 gallons per minute or less, against 2.5 gpm for a standard head — worth naming when you pick fixtures.
- Local codes can differ from the IRC; your contractor or building department has the final word.

### The prompt that keeps it your bathroom
Moving a toilet or a drain is where bathroom budgets go. Pin them in every prompt:
- “Remodel this bathroom in [style].”
- “Floor: [tile size, finish, colour, grout]. Walls: [tile or paint, layout]. Vanity: [type, width, top].”
- “Shower or tub: [keep / glass walk-in / new tub]. Fixtures: [finish]. Lighting: [mirror lights, ceiling].”
- “Keep the toilet, the shower position, the drain, the window, the door and the camera angle the same.”

### From picture to remodel
Use the image to choose a look, then get real tile and vanity samples and check them in your bathroom's own light — screens and AI both shift colours. Waterproofing, drainage falls and ventilation don't show in a picture but decide whether a shower lasts; a bathroom contractor will price those.
Remodelling the kitchen as well? The AI kitchen design generator works the same way for cabinets, counters and backsplash.

## FAQ
Q: What is an AI bathroom design generator?
A: A tool that redesigns a photo of your bathroom — tiles, vanity, shower or tub, fixtures, lighting and colours — from a text prompt, so you can see a remodel idea in your own room before you get quotes. On Kenerate AI you upload the photo to Seedream 5.0 Pro, describe the new bathroom and say what must stay, such as the toilet, the shower position and the window.

Q: Can AI remodel my bathroom from a photo?
A: Yes, as a picture. Shoot from the doorway with the lights on, upload the photo, describe the new finishes and add “keep the toilet, shower position, window, door and camera angle the same”. Bathrooms are tight and full of reflections, so compare the result with your photo: a moved toilet, a wider room or a new window comes from the model, not your house.

Q: Is there a free AI bathroom design tool?
A: You can start free. A new Kenerate account gets 25 starter credits, and Qwen Image 3.0 is on the free plan: an edit with one photo costs 9.9 credits, fine for trying tile colours or paint. Seedream 5.0 Pro, the best pick for a full remodel, costs 13.5 credits per image at 1K or 1.5K and 27 at 2K from one-time credit packs. Downloads have no watermark.

Q: Can I change only the tiles?
A: Yes. Open the photo in Edit Studio, choose Change Region, paint over just the floor — or just the shower wall — and describe the tile: size, finish, colour, layout and grout, such as “large matte terrazzo floor tile, light grey grout”. Everything you didn't paint stays as it was, so two versions differ by the tile alone.

Q: What are good AI ideas for a small bathroom?
A: Ask for the things that make small bathrooms feel bigger: a wall-hung or floating vanity so the floor shows underneath, large-format floor tiles with few grout lines, vertical tile on the walls, a clear glass shower screen instead of a curtain, a recessed shower niche, and a large mirror with lighting on both sides. Keep the toilet and shower where they are in the prompt so the ideas stay buildable.

Q: Can AI show my tub turned into a walk-in shower?
A: Yes — ask for it directly: “replace the tub with a walk-in shower with a clear glass screen, a linear drain and a niche; keep the toilet, vanity and window the same”. GPT Image 2.5 Sunburst is good at that kind of single, literal change. Whether it fits is a separate question: in the US the IRC asks for at least 900 square inches of shower floor with no side under 30 inches.

Q: Will an AI bathroom design meet building code?
A: No — it can't. An image model doesn't measure, so it may draw a toilet squeezed beside a vanity or a shower too small to use. The IRC, which most US states base their codes on, asks for at least 15 inches from the toilet's centreline to a side wall or fixture and 21 inches clear in front of it. Your local code may differ; your contractor will know.

Q: Can I use the real vanity, tile or fixtures I'm looking at?
A: Yes. Add the product photos as extra references next to your bathroom photo and say where each goes — “the vanity in image 2 on the left wall, the tile in image 3 on the floor”. Nano Banana 2.1 takes up to 14 images and Seedream 5.0 Pro up to 10. Check size and colour against the real sample; AI can draw a vanity wider than it is.

Q: Which model is best for AI bathroom design?
A: Seedream 5.0 Pro for most bathrooms: it remodels the whole room from your photo and is the default model for Change Region and Magic Eraser in Edit Studio. Use Nano Banana 2.1 to place real products, GPT Image 2.5 Sunburst for precise one-change edits, and Qwen Image 3.0 on the free plan for drafts. Per image: 13.5, 21, 11.7 (with one photo) and 9.9 credits.

Q: Is an AI bathroom design as good as a bathroom designer?
A: No — it is a fast way to try finishes and layouts, not a design service. It doesn't check drains, waterproofing, ventilation or clearances, or size anything to real products. Use the images to settle on a look, then take them to a designer or contractor. Moving a toilet or shower is the expensive part, so keep those fixed in your first ideas.
