Water in the garden does not need a pond. In a small space, a bowl in a bed, a trough by the patio, a narrow channel along the path or a stone with water bubbling out of it is enough. The options differ in how much space they need, whether they need electricity, how much care they take and how dangerous they are for small children. This article goes through them one by one, with pictures and with what you should know beforehand. Larger basins and ponds are covered in the articles Water basins in the garden and Designing a garden by the water.

At a glance
- Small children first: Even shallow water is life-threatening for them. If small children play in the garden, every open water surface needs to be secured, or you choose an option without an open surface.
- Still water in a bowl, basin or channel works without a pump. But it has to be cleaned regularly, otherwise mosquitoes breed in it.
- Splashing water needs a pump and therefore electricity, and outdoors only via a residual current device.
- Leaves, algae and frost are part of looking after every option, even the smallest.
First: small children and water
Small children can drown in just a few centimetres of water. The German Life Saving Association (DLRG) explicitly names garden ponds, paddling pools and even puddles as hazards and points out that drowning often happens silently and unnoticed. If a toddler falls head first into water, they often cannot lift their head out again. A shallow water bowl is therefore not automatically harmless.
What the DLRG recommends for securing water:
- fence off ponds and basins so that children cannot get to them,
- or fit a grid or metal mesh, firmly anchored just below the water surface,
- fill containers with water and plants with stones to just below the surface, or secure them with an anchored grid,
- close rain barrels firmly with a lid that children cannot open.
No safeguard replaces supervision. Also think of children who come to visit, and of neighbours' children if the garden is open. For a household with small children, a bubbling stone where the water disappears into a covered container under gravel is often the simplest solution (more on this below). Or you add the water only once the children are older, and use the spot as a bed or gravel area until then.
Which option suits your garden?
| Option | Space | Pump/power | With toddlers |
|---|---|---|---|
| Water bowl | one spot in a bed | not needed | grid or stones |
| Raised basin, trough | by patio or path | not needed | a rim alone doesn't protect |
| Channel | a strip by the path | not needed | secure like a basin |
| Bubbling stone | very little | yes | hardly any open surface if covered |
| Rain chain | at the gutter | no | secure the catch stone |
1. The water bowl: a calm point in the bed
A round, dark bowl sits in planting of lavender, blue fescue and silvery perennials. Next to it, a path of natural stone slabs leads to the terrace. The dark inside reflects sky and tree, and the plants grow right up to the rim. The bowl in this picture is large. In a small garden the same principle works with a much smaller bowl.
Suits gardens with lots of planting that lack a calm point. The bowl needs no pond excavation, no pump and just one spot in the bed. Needs: Still water in a container is a breeding site for mosquitoes. Germany's Federal Environment Agency (UBA) advises emptying water containers such as bird baths completely at least once a week. With a small bowl that is quickly done. With a large one it means a lot of water every week, so think about that before you buy.
It can be smaller, too: a Corten steel bowl among grasses and hydrangeas, here in a garden between dark house walls. In partial shade the water gets less sun, but more leaves fall into it under trees. Corten steel can shed rust at first and stain pale stone next to it.
2. Raised basin and trough: water at seat height
A long, rectangular Corten steel trough stands at the edge of a timber deck, filled to the brim with water. Next to it, a seating wall curves around a fire table, with grasses and lavender in between. Detail from a larger garden.
Suits patios and small courtyards. A trough needs no digging, and the water is where you sit. Limits: Water is heavy. One litre weighs about one kilogram, so a trough holding a few hundred litres weighs a few hundred kilograms. On a balcony, roof terrace or timber deck you therefore need to check beforehand whether the structure can carry it. A high rim stops people from tripping in. It does not protect against a toddler who climbs up. Whether a container may stay filled over winter is stated in the manufacturer's information. Anything that is not frost-proof is emptied before the frost.
3. The channel: water as a line
A long, narrow basin with a stone edge runs alongside a timber deck. A multi-stemmed tree is reflected in the water, and behind it steps lead up to a pergola with a lounge. Detail from a larger garden.
Suits long, rather narrow gardens. A channel needs only a strip of ground and leads the eye to the end of the garden. What this can look like in a terraced-house garden is shown in the example in the article Narrow garden. Needs: A channel has to be built watertight and exactly level, otherwise the water line sits visibly lower below the edge at one end than at the other. It has a lot of edge relative to its water surface, and leaves and algae collect along that edge. For small children the same applies as for any basin.
4. Bubbling stone and bubbler: water you can hear
In the first picture, a Corten steel basin that tapers towards the bottom stands on a bed of pebbles among coneflowers, lavender and grasses. Water bubbles up in the middle, and lights in the basin illuminate it in the evening. In the second picture, it bubbles out of a round stone bowl at the edge of some paving.
How it works: A pump pushes the water upwards, it runs back over the rim or the stone and is drawn in again. With many bubbling stones the water reservoir sits in a container in the ground, covered with a grid and pebbles. Then there is hardly any open water surface, which makes this option interesting for families with small children. Make sure the cover sits firmly and a child cannot lift it. The basin and the bowl in the pictures, by contrast, have an open water surface.
Suits very small gardens, courtyards and spots near the seating area where you can hear the splashing. Needs:
- Electricity. For the pump and for lights in the water. Manufacturers of pond and fountain pumps state in their instructions that the pump must be protected by a residual current device (RCD) rated at no more than 30 mA. The electrical installation belongs in the hands of a qualified electrician. Disconnect the pump from the power supply before reaching into the water.
- A solar pump works without a cable. Without storage, though, it only runs while light falls on the panel.
- Topping up. Water evaporates and splashes out, especially on hot days.
- Winter. The manufacturers recommend taking the pump out before the frost and storing it frost-free.
5. No pump, no cable: the rain chain
Chains hang from the roof edge of a covered timber deck into hollowed-out natural stone blocks. When it rains, the water runs down the chains into the stones. Detail from a larger garden.
Suits anyone who wants to see and hear water but doesn't want any technology. Limits: The water only flows when it rains. It has to be able to drain on from the stone, for example into a bed, a soakaway or a cistern. The picture does not show where it drains here. If water stands permanently in the hollow of the stone, it is a place for mosquito larvae like any container, and a risk for small children.
Care: algae, leaves, mosquitoes and frost
- Algae need light and nutrients. A spot in partial shade, no fertiliser and no soil washing into the water, plus regularly fishing out leaves, keep them in check. Open water rarely stays completely free of algae.
- Leaves fall into any water under trees. Plan the bowl or basin so that you can easily reach the edge.
- Mosquitoes like to lay their eggs in small pools of water. So empty containers without fish or other animals that eat larvae completely at least once a week. With a trough or channel holding a few hundred litres, that is hardly practical. According to Germany's Federal Environment Agency, flowing water is unsuitable for most mosquito species. Whether a small circulation pump in a basin is enough for that, however, is not established. Clarify this point before you build. Cover rain barrels tightly.
- Plants in the water: Use native species. Water hyacinth is on the EU list of invasive species and may neither be sold nor newly acquired in the EU, not even for your own garden.
- Frost: Take the pump out before the frost. Empty containers that are not frost-proof beforehand.

Frequently asked questions
Is a shallow water bowl dangerous for toddlers?
Yes. Small children can drown in just a few centimetres of water, and it often happens silently. The DLRG recommends fencing off water or securing it with a firmly anchored grid just below the surface. Containers can also be filled with stones to just below the surface. None of this replaces supervision.
Does water in a small garden need electricity?
Still water in a bowl, trough or channel does not. If you want splashing or want to circulate the water, you need a pump. According to the manufacturers' instructions, it must run via a residual current device rated at no more than 30 mA, and a qualified electrician does the installation. A solar pump without storage only runs in daylight.
How do I prevent mosquitoes in a water bowl?
By changing the water regularly. Germany's Federal Environment Agency advises emptying water containers such as bird baths completely at least once a week. The bigger the container, the more work that is. So choose the size according to how often you will really empty it.
Can I put a water basin on the patio?
On a ground-level patio, usually yes. On a balcony, roof terrace or timber deck you need to check beforehand whether the structure can carry the weight. One litre of water weighs about one kilogram, plus the container and any stones.
