Hello everyone,
I am planning to place an aquarium of about 120 liters (30 gallons) on an IKEA KALLAX shelf unit to use it as a stand, but I am unsure whether the shelf’s load capacity is sufficient for this. The KALLAX is generally designed for light to medium loads, but aquariums bring significant weight due to water and additional equipment, as well as concentrated load points.
My specific question is: Is the IKEA KALLAX shelf unit strong enough to serve as an aquarium stand for a 120-liter (30-gallon) tank, or is there a risk that the load might be too high and could damage the furniture?
I have heard that especially the shelves and connection points can be critical, as they do not distribute the weight evenly. Also, I would like to know whether reinforcements or support plates can make the shelf safer, and how long such a setup might maintain its stability before it starts to weaken.
Who has experience using the KALLAX as an aquarium stand, possibly with tanks of similar or larger size? Are there any structural improvements you would recommend?
Thanks for your insights!

Is the IKEA KALLAX shelf sturdy enough to be used as a stand for a 120-liter aquarium, or is there a risk that the load is too heavy and could damage the furniture?Basically, the KALLAX shelf is not specifically designed to support heavy loads like aquariums. According to the manufacturer's specifications, the maximum recommended load per shelf is about 13-15 kg. A 120-liter aquarium (including water, glass, and substrate) typically weighs around 130-150 kg (290-330 lbs). The weight is distributed over an area, but this still significantly exceeds the intended load capacity.
The most critical parts are the crossbars and joints between the shelves, as they are not reinforced load-bearing structures. Without additional reinforcements or a separate supporting frame, there is a high risk that the shelf will deform, the shelves will sag, or the joints will be damaged.
Recommendation: For aquariums of this size, it is advisable to use furniture specifically designed for the purpose or a metal/wood frame that can safely carry loads of several hundred kilograms. Alternatively, the KALLAX can be strengthened with sturdy wooden panels and additional supporting elements to better distribute the weight.
In short: in its original condition, the KALLAX is definitely not suitable for supporting a 120-liter aquarium.

To be precise, a 120-liter tank holds about 120 kilograms (265 pounds) of water plus the weight of the glass and other components—that’s quite heavy. The KALLAX is great for books, decorations, and a few plants, but as an aquarium stand… well, the shelf turns into a bit of a surprise package 😉
However, I’ve heard that some people manage to work around this issue with a little DIY skill. For example, adding reinforced wooden boards or even metal braces to better distribute the weight. Sure, that’s not standard IKEA stuff, but with some handyman ability, it can definitely work.
So: it’s best not to put a 120-liter tank on the original KALLAX without modifications, but with some reinforcement, you can create a fairly sturdy frame. Safety and stability should always come first—better to measure and build carefully than to deal with a water disaster later 😉

Nathanaelk27 May 2024 07:28Good morning everyone,
I would like to go into some technical details here because I believe that the topic of load capacity for aquarium stands is often treated too superficially.
The KALLAX shelf is made of particleboard with a melamine coating and has standard thin shelves supported by relatively slender central panels and side walls. This design is optimized for even load distribution and moderate weights, not for localized heavy loads.
For a 120-liter (32-gallon) aquarium, we are talking about approximately 120-150 kilograms (265-330 pounds) acting on an area of about 80 x 30 cm (31.5 x 12 inches). This means the load is very high and strongly concentrated in one spot – leading to an increased risk of shelf sagging, especially in the middle of the compartments.
If you still want to use a KALLAX, you should definitely consider the following points:
1. Reinforce the shelves with thick plywood panels (at least 18 mm (0.7 inches)) placed on top of the original shelves to create a more load-bearing surface.
2. Attach additional central supports or metal profiles underneath the shelves to reduce bending forces.
3. Make sure the shelf is placed on a level, stable surface to avoid uneven loading caused by tilting or unstable boards.
4. If necessary, use a separate load-distributing base plate to spread the aquarium’s weight across the entire shelf structure.
5. Monitor the condition of the furniture over time – wood-based materials like particleboard are sturdy but sensitive to moisture and can deform or soften under constant load.
Without these measures, in my opinion, you are dealing with a case that will require repair and may lead to severe damage in the long run.
I would be interested to know more about your setup (dimensions of the aquarium, whether there is an underlay, etc.) to provide more specific recommendations.

The tank measures approximately 100 cm x 30 cm x 40 cm (LxWxH), so it has a volume of about 120 liters (31.7 gallons). A thin wooden board as an underlay between the aquarium and the KALLAX shelf is planned to prevent pressure points, but thicker plywood boards or metal reinforcements have not been considered so far.
The shelf is level and placed on a stable surface, so there should be no additional load distribution issues caused by uneven flooring. By the way, I now have the version of the shelf with 4 compartments side by side – the aquarium is meant to be positioned roughly centered over two adjacent compartments to distribute the surface area a bit more.
My goal is to improve stability without completely rebuilding the shelf with new materials. Are there practical and cost-effective solutions to at least extend its lifespan? Maybe non-slip rubber mats or additional braces or something similar?
