Can You Put an Above Ground Pool on Grass?
You can sometimes place an above ground pool on grass, but only on level, firm ground that the manufacturer allows. Grass alone is usually not a safe long-term base.

Is it possible to have an above ground pool on grass?
In a word, yes, though there are caveats. You will not want to put an above ground pool on any grass that is soft, uneven or has a tendency to settle. While a temporary arrangement in the backyard might make do with grass as a top layer, the support beneath has to be firm and level in keeping with the pool manual. Let the base shift and you risk leaning walls, a damaged liner and undue stress on the structure.
Pre-installation: what to look for
The first thing to examine is the site itself before worrying about the water.
- Levelness: The pool requires an even base all the way around.
- Firmness: Walk the area and put your foot down to see if there are any spongy patches.
- Debris: Be on the lookout for rocks, roots, weeds and bumps of dirt; they can throw off the frame and harm the bottom of the pool.
- Drainage: Steer clear of places where the lawn remains wet after a rain or watering session.
Should you come across a bumpy or muddy section, do not attempt to compensate for it by adding more water to the pool. Either re-site the installation or get the ground ready properly.
Are there times when putting a pool on grass is acceptable?
There are instances, but only with certain models and as part of a correct setup. It is up to the manufacturer’s instructions to determine what is permissible. Most pools require something more substantial than grass alone, be it a compacted base or some other accessory called for in the manual.
A few things to keep in mind:
- Stick to the manual for setup and use only approved materials.
- Make sure the liner is shielded from rough soil and sharp weeds.
- Clear the perimeter so nothing blows into the water.
Some may opt for artificial turf, but only if the pool maker is okay with it and the surface is stable. Artificial grass does not in itself remedy a soft or uneven foundation.
The trouble with grass underneath
It is convenient, but over the course of the summer grass can be the source of some avoidable headaches. The weight of the water can press down on the soil in an uneven fashion. Moisture has a way of softening the earth below, while organic matter and weeds can decay. This kind of uneven support will show up as wrinkles in the liner or a pool wall that is not quite straight. If the frame looks crooked or is shifting, put a halt to use until it is righted.
A safe approach to setup
Follow this order of operations:
1. Have the manufacturer manual in hand before you start moving anything. 2. Find a spot in the yard that is level and well-drained. 3. Clear out all the sticks, rocks and roots. 4. Get the base prepared as directed. 5. Put the pool in and verify it is level prior to a full fill.
An uneven site will not be made safe by the water in the pool.
When to bring in a pro
If the soil is sandy or prone to saturation, or the yard is sloped, a qualified contractor or installer is the way to go. The same applies if you need more than basic grading or are in doubt about whether your particular model is suited for grass.
And if you find the pool is already under structural stress or sinking, cease use and consult the manual. For any maintenance on the skimmer or circulation, shut the pump off before you open access points and hearken to the equipment and chemical labels. Do not put your hands in operating suction gear and never swim if there is an electrical issue or the water is otherwise unsafe.
