Best AI Bathroom Design Apps 2026: Which Ones Keep Your Plumbing?

AI bathroom design apps help you see how your bathroom could look before making changes. Upload a photo and choose a style to try new colors, cabinets and fixtures. We compared six apps using the same bathroom photo to see how well they kept the toilet, sink and shower in place and how real the results looked. We also asked ChatGPT to redesign the room as a separate example.

Disclosure: DecorAI is our product. We reviewed its result using the same checks as the other apps and explain its limits below.

Quick Comparison

How We Compared the Results

We tested six AI bathroom design apps using the same original bathroom photo on October 19, 2026. We checked how well each app kept the main bathroom layout and how realistic its finished image looked.

Each app received a score out of eight, with up to four points for each of these two criteria:

• Room Layout: We checked whether the sink, toilet, shower and window stayed in their original positions. We also checked whether smaller details, such as the wall vent, were preserved.
• Image Quality: We checked how clear and realistic the tiles, mirrors and fixtures looked. Blurry details, bent edges and unusual shapes lowered the score.

Half points were used to reflect smaller flaws in the results. We used the original bathroom photo below to compare each app's results and see how closely they matched the starting room.

Why the Bathroom Layout Matters

Moving a toilet or shower can mean opening the floor and changing pipes. This adds work and may increase the cost. Even a new sink cabinet may need pipe changes if the sink or faucets are different.

Compare each design with your original photo before choosing a new look. Keeping the main items in place may help control costs. Our bathroom remodel cost guide explains what different budgets may cover.

Best for: Seeing how a darker bathroom could look with white cabinets and lighter colors.

Where it falls short: Some cabinet handles and shower parts look blurry or uneven. Changes to the toilet and vent make the result less faithful to the original room.

Can ChatGPT Design Your Bathroom?

ChatGPT can create a new bathroom design from an uploaded photo. Describe the changes you want and the items you want to keep. Access to image tools depends on your plan and settings.

We uploaded the same bathroom photo used for the other app tests and entered this prompt: "Redesign the uploaded bathroom photo in a realistic, modern spa style. Use warm beige tiles, a natural wood vanity, soft lighting, and simple, elegant fixtures. Keep the original bathroom layout as close to the photo as possible. Preserve the sink, toilet, shower, window, wall vent, doors, and their positions. Do not add or remove major fixtures or change the room's structure. Make the materials, reflections, edges, and proportions look natural and believable. Create a high-quality, photorealistic image in a 16:9 landscape ratio."

ChatGPT created a lighter bathroom design with wooden cabinets, cream surfaces and soft lighting.

Kept the plumbing: The sink, toilet, shower and window stayed in similar areas. The toilet tank and wall vent remained, although some sizes and distances looked different.

Best for: Creating bathroom design ideas from written instructions and asking for further changes.

Where it falls short: Written instructions do not guarantee that every item will stay in place. Small details and room sizes can still change in the image.

Which App Is Right for Your Bathroom?

When a Photo App Is the Wrong Tool

A photo app helps you see a new bathroom look. A measured planner helps you work out whether the changes will fit. Use a planner if you want a double sink, a larger shower or a different toilet position. Enter the room measurements and check the space around each item, including room for doors and drawers to open. These tools serve a different purpose, so we have not included them in the photo app scores.

• Planner 5D: Draw a bathroom layout and view it from above or in 3D. Its free version lets you start planning online.
• Houzz Pro: A tool for designers and remodelers who need floor plans and project estimates. It can use items from a 3D plan to help prepare an estimate.
• IKEA Bathroom Planner: Plan a bathroom around IKEA furniture and compare cabinet choices. It is useful when you intend to buy from IKEA.

Best Free AI Bathroom Design App

DecorAI is a good choice for trying bathroom designs without a watermark. Its free 1-day trial includes 3 designs using your own bathroom photo. A card is required. After the trial, the monthly plan costs $24.

REimagineHome is the best fully free option in this comparison if you want to try five designs without adding payment details. The free image we got had a watermark, which made some bathroom details harder to see.

Before choosing an app, check how many designs its free offer covers, whether it requires payment details, and whether the images have a watermark. Credits are not always equal to designs.

How to Photograph Your Bathroom for AI

A clear photo helps the app see your bathroom properly. Take a few minutes to prepare the room before uploading.

Shoot From the Doorway

Stand near the door or in a corner. Try to include the sink, toilet, shower or bath and window in one picture.

Turn On the Lights

Turn on the lights and open the blinds. Make sure the room is bright enough to see clearly. Avoid glare that hides details in the mirror.

Clear the Bathroom

Move bottles, clothes and towels that cover the surfaces. Close the toilet lid so the room looks tidy.

Hold the Camera Straight

Keep the camera level. Check that the walls and cabinet edges look straight before taking the photo.

Say What Should Stay

Describe the look you want and name the items that should stay in place. If the app has a negative prompt box, use it to list colors, objects or materials you do not want.

For example: "Use white tiles, a walnut cabinet and brass faucets. Keep the sink, toilet, shower and window where they are." Negative prompt: "No dark tiles, no bathtub, no gold mirror."

What AI Bathroom Design Apps Cannot Do

AI bathroom apps show how your room could look. The picture does not give you building instructions or show the pipes and wires inside the walls. It also cannot tell you whether water could leak.

Some items in the design may not be available to buy. Colors and materials may look different in real life. Show the design to the person doing the work. Check product sizes and real samples before buying. If you use an online cost calculator, treat the price as a rough guide. Ask for a quote based on your own bathroom.
