But since each septic tank has different designs, features, and specs, you may not know which one is ideal for you. To help you with this, we included a buying guide and cost section in this article so you can sift through our options effortlessly.

How Much Do Septic Tanks Cost in Malaysia?

Septic tanks are sold by hardware shops, eCommerce platforms, and manufacturers alike. In Malaysia, they cost around RM720 to RM9,620, depending on the size and material.

In a nutshell, fibreglass and concrete septic tanks are more expensive than plastic and steel types. That’s simply because the first two have greater durability and damage resistance than the others.

Prices online usually exclude installation service costs. Since this will largely vary depending on the work that needs to be done, you have to enquire with the seller to get an accurate quote.

What to Consider When Buying a Septic Tank

Before you buy a septic tank, here are the important factors you need to consider:

1) Material

First, you have to choose the right septic tank material that fits your needs and budget. Here are the different types of material available on the market:

  • Concrete

Concrete septic tanks are very hardy and durable and can last up to 40 years or more. They are also low-maintenance and will therefore save you costs for maintaining or replacing them.

As they are less flexible than plastic kinds, they can crack easier. And because they are cumbersome, installing a concrete septic system will require heavy-duty equipment.

  • Fibreglass

Fibreglass is a common plastic material that’s reinforced with glass fibre. In terms of strength to weight ratio, fibreglass is a great deal better and more durable and impact-resistant than steel.

Similar to concrete septic tanks, fibreglass units can stay as long as 40 years or more. However, they are more expensive than plastic and steel chambers.

  • Steel

Steel septic tanks are the least durable in terms of material type. They can last up to 20 to 25 years and can rust earlier than the given period.

As such, it can also be dangerous, as the person may mistake the rusted steel top lid to be a part of the ground and fall into the tank accidentally.

  • Plastic

Plastic is fairly durable for septic tanks that can last as long as 30 to 40 years. However, this will depend on the quality of the plastic.

Another advantage is that plastic septic tanks are lighter than their counterparts. That makes them easy to transport and install on-site.

That said, they tend to require more maintenance than concrete or fibreglass tanks.

2) Size & capacity

Septic tanks come in many different sizes depending on the brand or product. The size and capacity you have to pick should depend on the house size, the number of occupants, and how much water is used.

To know what septic tank size is best to buy for your house, kindly refer to the table below:

No. of BedroomsHouse Size (sq ft)Tank Capacity (Gallons)
1 or 2Less than 1,500750
3Less than 2,5001,000
4Less than 3,5001,250
5Less than 4,5001,250
6Less than 5,5001,315

3) Ease of Installation

Ease of installation doesn’t only concern the speed or ease of setting your septic tank under the pit. But it will also concern the costs, performance, maintenance, and aesthetic finish afterward.

After all, you want the septic tank to be stable under the soil, working smoothly and efficiently, and won’t need to be maintained except once every two years.

Steel, fibreglass, and concrete septic units are heavier and harder to install while plastic ones are the easiest since they are lightweight.

Also, we suggest that you get a professional contractor to do the work for you rather than DIY. This way, you will save time, effort, and have peace of mind that the install has been done well.

4) Warranty

So that you’ll get value for money and not worry about unexpected defects, you should always look for a septic tank with a warranty.

Though some companies aren’t explicit about it online, you can ask the seller whether or not they offer one. They should and this can go from a single year to the entire life of the product.

Of course, the lengthier the warranty, the better!

5) Price

Septic tank rates can range from RM720 to RM9,620 in Malaysia. This is often exclusive of installation service costs so you will also have to factor these in too.

Once you’ve looked into the material, installation ease, warranty, and size, the price is easy to decide on. Pick one that will give you the best bang for your buck in terms of durability and less frequent maintenance.
