The couple on the fence
They'd love a hot tub but worry it will eat the kids' lawn. Two pictures of their own garden, and the question shifts from "yes or no" to "square or round".

A hot tub takes up more room than you'd think, and once it's delivered it isn't going anywhere. On the seller's site it sits beside an infinity pool, nothing like your lawn between the house and the back wall. This workflow starts from a photo of YOUR garden and puts two models in it: a hot tub on a wooden deck, then a wood-fired Nordic tub.
The hard part is scale. An image model left alone draws a tub too big or too small, or redoes the garden while it's at it. The prompt gives the width in metres, the shape and the surroundings. Flux Kontext adds the tub and keeps the house, the wall and the hedge; the demo also shows the details it didn't follow.
To compare with an actual pool, see the pool visualizer; to shade the corner, the pergola. Both tubs cost twelve credits.
Actual renders from the demo
These are the files of the workflow above, exactly as the models produced them, unretouched. The starting point is shown when there is one.
Starting point
Render
Who it is for
Homeowners considering a hot tub, dealers showing a model in the customer's garden, holiday rental owners.
Which files to provide
A photo of the garden with the chosen spot, the shape and width of the tub, and what surrounds it.
How it works
- 1
Photograph the garden
From the house or the patio, with the chosen spot clearly in view, in daylight. Move the hose and any furniture off the area first.
- 2
Give the size
Width in metres, number of seats, square or round. A five-seat hot tub is a little over two metres across.
- 3
Describe the surroundings
Wooden deck, concrete pad, steps, cover, towels. What surrounds the tub tells the model whether it sits on top, is sunk in, or is flush with the ground.
- 4
Check on site
Mark out the area with four stakes, look at what the neighbours can see, then talk base and electrics with the installer.
Variations and use cases
The same canvas, tuned for different needs: each variation is two or three lines of prompt away.
The hot tub dealer
In the showroom, the salesperson asks for a photo of the garden and shows the customer the display model in place, at the right size. The customer leaves with a picture to show at home.
The holiday let that wants an edge
The owner of a countryside rental compares a hot tub and a Nordic tub on the garden photo, then picks the one that suits the style of the old farmhouse and its guests.
The overlooked garden
The hedge is tall, but next door has an upstairs window. The picture helps find the least exposed spot before pouring a concrete base that won't move again.
The runner and recovery
He's looking at a Nordic tub for after long runs, wood-fired with no electrical hookup. He checks how the tub looks and where the stove goes in his small garden.
The house for sale
The seller of a house with a large garden shows buyers what a hot tub corner would look like on the bare lawn, clearly labelled as a simulation, so they can picture the garden in use.
Common mistakes
Not giving the width
"Add a hot tub" lets the model pick the size, and it often gets the scale wrong. Give the width in metres and the number of seats.
Mixing up hot tub and pool
Without a shape or a size, the model may draw a small plunge pool. Write "hot tub for five people" or "round Nordic tub".
Trusting every detail
In the demo, the square sunken tub came out rectangular and sitting on the deck. Check the render and run it again if the sunken look matters to you.
Forgetting access and electrics
A hot tub needs a base that can take the weight, a dedicated electrical supply and a way in for delivery. The picture shows the look; the installer checks the rest.

Does the garden change?
The house, the back wall and the hedge stay. In the demo, Kontext also removed the garden hose and made the lawn greener.
Does it work on a paved patio?
Yes: write "on the paved patio" instead of "on the lawn". For a sunken tub, say how high the edge should sit.
Can I try an inflatable hot tub?
Yes: describe it, round, grey, about 1.8 metres, on a ground mat. It's also a cheap way to check the space before a bigger purchase.
How much do the two tubs cost?
Twelve credits, six per render on Flux Kontext. A third model on the same photo costs six more.
Why Flux Kontext?
Because it adds an object to a photo without redrawing the setting: the beige house, the breeze block wall and the hedge stayed identical on both renders.
What's the difference between a hot tub and a Nordic tub?
A hot tub is a shell with jets, heated electrically, with a cover. A Nordic tub is a wooden tub heated by a small stove, no jets, more rustic.
Why is the Nordic tub's stove separate?
That's a slip by the model in the demo: the prompt asked for it on the side of the tub, and it stands beside it. Write "stove attached to the side of the tub" or run it again.
What output format?
The format of your photo, here 4:3. A garden photographs best in landscape, from the house.
