You can use a bird bath or a small pot, but today Millie is transforming an old bathtub into a water feature – with added fish to create a mini ecosystem.
What you need:
Bath or other tub/container
Silicone to seal plug
Saucer to cover plug (optional)
Gravel
Plants
Aquatic soil mix or garden soil (see notes)
Washed sand
Bricks to support pots
Fish! (optional)
Water conditioner (optional)
Wire mesh safety cover
A shade area (optional)
A log or other way for animals to safely climb out
What you do:
Pick a spot with plenty of sun – most water plants need at least half a day’s sun.
To make sure the plug doesn’t leak, Millie has sealed it in with silicone but has also put a screw cap into the waste so she can undo it and let the water out to move it or clean it. She puts a small saucer over the plug to protect it.
She puts about 4 litres of gravel into the bottom of the bath to act as a base for pots and create a mini ecosystem.
Now fill the bath.
Plants:
Millie uses indigenous plants in her pond – it’s important to think about what you grow in a water feature as birds can easily transport seeds or bits of plants to other waterways, where they can cause a major problem.
Some plants grow on the edges of waters; these are marginal plants, such as reeds and sedges.
Others need to be fully submerged – these are aquatic.
Millie will grow her plants in pots rather than filling the base of the bath with soil.
For both marginal and aquatic plants, you need a growing medium that is heavier than regular potting mix, as this will simply float and it contains a lot of nutrients, which can cause unwanted algae to grow. Millie pots her seedlings up in a special aquatic mix but you can also use a heavy clay-loam mix from your garden if you’re confident it is fairly weed-free.
To hold the growing mix in place, cover it with a layer of washed sand then a layer of gravel.
Gently lower the pots into the water to allow any air to escape.
The pots of aquatic plants can sit on the bottom of the bath, while the marginal plants should be raised up on bricks or upturned pots so that only the roots are under water and the foliage sits above.
Fish: to keep mosquitoes at bay, Millie has sourced some native fish, Southern pygmy perch (Nannoperca australis), which will eat mosquite larvae while leaving any frog tadpoles alone; they are also suited to the local climate.
Before adding them, she treats the town water with a water conditioner (available from aquarium shops) to remove any chlorine. If using rainwater, this is not necessary.
As a safety measure, Millie has cut a piece of stiff wire mesh to size and uses this to cover the bath. Pond regulations vary around Australia, so check what guidelines apply in your area.
Millie has added a small deck to one end to provide some shade and a vantage point for visitors.
She also adds a frog log to provide a safe exit point from the pond for any frogs or other creatures.
Featured plants:
Water ribbons (Cycnogeton procerum)
Water Milfoil (Myriophyllum sp.)
Purple Loosestrife (Lythrum salicaria)
Poison pratia (Lobelia concolor)
Common Nardoo (Marsilea drummondii)

This looks fantastic. You are truly inspiring ,thank you!🌻🇿🇦
this is bad advice, you need to wait at least a few months before putting fish in…
Frog log, LOL they got to get up there first!
Well that looks pretty ugly.
Just wondering why no replies from Gardening Australia to any comments?
Just what I need- I have the bathtub but no idea how to do the filter! Thanks 😁
Is there a need to have an overflow system of some sorts drilled in to the tub? If it rains the the water level rises, will the fishes get thrown out of the tub?
Does anyone know if you have a bathtub with no feet does it need to be supported on the sides to stop it tipping?
I love your video! How do the frogs get up there? I’m installing a small pond myself and I was thinking of putting a staircase for them LOL
Sorry nice idea but not thought through at all! Look at the comments you could learn a lot!
Very interesting 👌
You really covered the subject and every question I had. 🌿💚🌿
first present in Indonesia🇲🇨
This is brilliant
How about mosquitoes? Is there some easy way to control them?
Wish they gave a rough cost
any edible plants?
Don’t see how it will benefit the chooks , frogs will probably have a hard time jumping that high too
This is so creative and it looks great. It never occurred to me to use a tub like this – I honestly always thought that ponds had to be in-ground. Will we get an update on the pond? I’m so curious to see how it evolves over time and what animals you’ll get in the garden.
Isn’t Milfoil toxic to pets?
Love this. I’d be interested in seeing something on a smaller scale.
the log is a great idea so frogs can easily enter or leave the bathtub.
I added two big rocks in the deep old bath so that the tip of each rock is slightly out of that water.. with lots of hiding places around the rock as good hiding places for frogs.
But I prefer the bath tub sunk into the ground – helps keep the water cooler. I used an old bathtub and painted the inside a dark grey to blend in
AND
I used a former wide screen door attached on top of the bath tub with a long piano hinge on one side of the top. (padlock too – more about that in a moment) that meant too that the decorative metal could handle an adult walking over the top .
But I had to change the mesh on the old screen door as the mesh was far too small mesh.the new more open mesh was better and the frogs could enter and exit more easily. BUT a cat could not use a long paw to get closer
the padlock on the latch I attached meant that a curious child could not try to lift the lid and could not enter the bath filled with water so was safer with children present. the children can even sit on the top and look into the water because the metal door is bigger and very strong and well secured to the metal bath below.
Should’ve dug that pond into the ground imo.
