The Best Water Filtration Option for Melbourne Apartments, Units, and Townhouses
If you live in a Melbourne apartment, unit, or townhouse, your water filtration options are different from those of a standalone house. You cannot install a whole-house water filter because the water mains are shared and controlled by the body corporate or building management. You do not have direct access to the main line entering the building, and any work on shared plumbing typically requires approval that is difficult, slow, or simply not available.
The good news is that there is one option that works perfectly in any apartment or unit, requires no body corporate approval, and gives you some of the best drinking water quality available: an under-sink reverse osmosis system. Installed beneath your kitchen sink with a dedicated drinking water tap, an RO system removes up to 98% of contaminants from your water. It connects to your cold water supply under the sink and drains into the existing waste line. No shared plumbing is touched. No building modifications are needed. The installed price is $3,300 including GST.
This guide explains why apartment and unit living creates a unique filtration challenge, what your options actually are, how the installation works in an apartment setting, and what you need to consider if you are renting rather than owning.
Why a Whole House Water Filter Is Not Practical for Apartments
A whole-house water filter connects directly to the main water line entering a property and filters every drop of water before it reaches any tap, shower, or appliance. In a standalone house, this is straightforward because you own and control the mains entry point. In an apartment or unit complex, it is a different situation entirely.
Factor | Standalone House | Apartment / Unit |
Water mains access | You own the main entry point. Full control. | Shared mains controlled by the body corporate. No individual access. |
Whole-house filter | Connects to the mains. Filters the entire home. | Not possible without body corporate approval and modifications to shared plumbing. |
Body corporate approval | Not required. You control your own plumbing. | Required for any work on shared infrastructure. Often slow or denied. |
Under-sink RO system | Available as an option alongside the whole house. | The ideal solution. Connects to your individual cold water supply under the kitchen sink. No shared plumbing is involved. |
Installation disruption | Minimal. Standard plumbing connection at the mains. | Under sink RO: minimal. Installed inside your kitchen cabinet in approximately 1 to 2 hours. |
Portability, if you move | Whole-house filter stays with the property. | An under-sink RO system can potentially be removed and reinstalled at your next property. |
The bottom line: if you are in an apartment, unit, or townhouse with shared water infrastructure, a whole-house filter is off the table unless the body corporate agrees to install one for the entire building (which is rare). An under-sink reverse osmosis system is the practical, effective, and affordable alternative.

How an Under-Sink Reverse Osmosis System Works in an Apartment
A reverse osmosis system fits neatly under your kitchen sink inside the cabinet. It connects to the existing cold water supply line and drains waste water into the sink drain pipe. A small dedicated tap is installed on your benchtop or sink for dispensing filtered water. Here is what the system includes and how it works in an apartment context.
What Is Included in the Installation
- Complete 7-stage high alkaline reverse osmosis system
- Standard chrome drinking water tap (installed on the sink or benchtop)
- Connection to your cold water supply under the sink (uses a standard saddle valve or T-fitting)
- Drain line connection (connects to the existing sink waste pipe)
- Pressure and flow testing after installation
- System walkthrough and filter replacement demonstration
How the 7 Stages Purify Your Water
The system passes your tap water through seven filtration stages. Each stage targets different contaminants, and together they remove up to 98% of dissolved impurities.
Stage | Filter Type | What It Removes |
1 | Sediment pre-filter | Sand, rust, dirt, and particles before they reach the finer filters |
2 | Carbon block pre-filter | Chlorine, chloramine, and organic chemicals that would damage the RO membrane |
3 | Secondary carbon pre-filter | Remaining chlorine and chloramine traces for full membrane protection |
4 | RO membrane (0.0001 micron) | Heavy metals, fluoride, dissolved salts, bacteria, viruses, pharmaceuticals, and up to 98% of total dissolved solids |
5 | Post-carbon polisher | Final taste and odour improvement after the storage tank |
6 | Mineral restoration | Adds back beneficial minerals (magnesium, potassium) for improved taste and hydration |
7 | Alkaline enhancement | Raises the pH for a smooth, slightly alkaline drinking water |
The result is pure, mineralised, great-tasting drinking water from a dedicated tap on your kitchen bench. For a full explanation of the science behind each stage
Apartment Water Filter Options Compared: What Actually Works?
There are several water filter products marketed towards apartment dwellers. Here is an honest comparison of how they stack up against each other, specifically for Melbourne apartments and units.
Option | Cost | Chloramine? | Heavy Metals? | Fluoride? | Body Corp? |
Jug filter | $30 to $60 | No | No | No | Not needed |
Tap-mounted filter | $40 to $100 | Limited | Limited | No | Not needed |
Benchtop gravity filter | $150 to $400 | Some models | Some models | No | Not needed |
Under-sink carbon filter | $300 to $700 | If rated | Some | No | Not needed |
Under sink RO (7-stage) | $1,100 | Yes | Yes | Yes | Not needed |
Whole-house filter | $1,100 | Yes | Yes | No | Required |
The under-sink reverse osmosis system is the only apartment-friendly option that removes chloramine, heavy metals, fluoride, and dissolved contaminants. Every other option either requires body corporate approval (whole house) or provides significantly lower filtration quality. Jug filters and tap-mounted filters are better than nothing, but they leave most contaminants in the water, particularly chloramine, which is relevant if you live in Melbourne’s western suburbs.

Renting vs Owning: What Changes for Water Filter Installation?
Whether you own your apartment or rent it affects what you can install and what approvals you need. Here is how the two situations differ.
Factor | Apartment Owner | Renter |
Under-sink RO system | Yes. You can install without body corporate approval as it connects to your private plumbing only. | Requires landlord permission. The system connects to the cold water supply and adds a tap hole to the benchtop or sink. |
Benchtop or jug filter | Yes. No installation or approval required. | Yes. No installation or approval required. You take it with you when you leave. |
Whole-house filter | Body corporate approval needed. Rare in practice. | Not available. You cannot modify shared building infrastructure as a renter. |
Tap hole for RO system. | You can drill a tap hole in your own benchtop. If stone, a specialist may be needed. | Ask your landlord. Some landlords see this as a property improvement. Others may refuse. |
Can you take it with you? | The system stays with the property if you sell, adding value for the next owner. | A plumber can remove and reinstall the RO system at your next property. The tap hole remains. |
Cost responsibility | You pay for installation and ongoing filter replacements. | You pay for installation and ongoing filter replacements. Some landlords may contribute to property improvement. |
What Renters Need to Know
If you are renting a Melbourne apartment and want an under-sink RO system, here is the approach that works best:
- Talk to your landlord or property manager first. Frame it as a property improvement. An under-sink water filter with a dedicated tap is an upgrade that adds value to the kitchen and makes the property more attractive to future tenants.
- Offer to cover the installation cost yourself. At $1,100, it is a one-time expense that you benefit from for the duration of your lease.
- Ask if the landlord wants the system left in place when you move. Many landlords are happy to keep it because it improves the property. If they agree, you leave the system and avoid the cost of removal and reinstallation.
- If the landlord says no to plumbed-in filtration, a benchtop gravity filter is the best non-plumbed alternative. It is not as effective as reverse osmosis, but it does not require any installation or modifications.
How the Installation Works in an Apartment Kitchen
Installing a reverse osmosis system in an apartment is the same process as in a house. The system fits inside the cabinet under your kitchen sink. Here is what the installation involves and what apartment-specific considerations apply.
What Your Plumber Needs Access To
- The cold water supply line under the sink (every apartment has one)
- The sink waste pipe (for the RO drain line connection)
- A power point nearby (not required for most gravity-fed RO systems, but check with your installer)
- Enough cabinet space under the sink (the system and storage tank are compact and fit in standard apartment under-sink cabinets)
The Dedicated Drinking Water Tap
A small, dedicated drinking water tap is installed on your benchtop or sink for dispensing the purified water. This requires either an existing tap hole (some sinks have a spare) or drilling a new hole. Standard benchtops are straightforward. Stone benchtops (granite, marble, engineered stone) require specialist drilling, which your plumber can arrange as an additional service if needed.
Installation Time
A typical apartment RO installation takes approximately 1 to 2 hours. There is no need to shut off water to other units or access shared plumbing. The work happens entirely within your kitchen.
Apartment Building Access
If your apartment building has restricted access (security doors, concierge, parking barriers), let your plumber know the details when you book so they can plan accordingly. Select Plumbing regularly installs systems in apartment buildings across Melbourne, including in the CBD, Southbank, Docklands, South Yarra, St Kilda, Richmond, Footscray, and throughout the inner suburbs.
What Does an RO System Remove From Melbourne Apartment Water?
Your apartment receives the same treated water supply as every other Melbourne home. It goes through the same treatment process and travels through the same distribution network. The contaminants in your tap water are the same whether you live in a house or a high-rise.
A 7-stage reverse osmosis system removes:
- Chlorine and chloramine (treatment disinfectants, including chloramine used in western suburbs supplied by Greater Western Water)
- Heavy metals, including lead, copper, and mercury
- Fluoride (added during treatment, removed by the RO membrane)
- Dissolved salts and total dissolved solids (TDS)
- Bacteria, viruses, and microorganisms
- Pesticides, herbicides, and volatile organic compounds
- Disinfection by products (trihalomethanes)
- Pharmaceutical traces and endocrine disruptors
In older apartment buildings (particularly those built before 1989 in suburbs like Fitzroy, Carlton, St Kilda, South Yarra, Prahran, and Richmond), the internal building plumbing may contain lead solder in pipe joints and corroded copper pipes. An RO system is especially valuable in these buildings because the membrane effectively removes these heavy metals from your drinking water.
Frequently Asked Questions
Can you install a water filter in a Melbourne apartment?
Yes. An under-sink reverse osmosis system can be installed in any Melbourne apartment, unit, or townhouse. It connects to the cold water supply under your kitchen sink and does not require any work on shared building plumbing. No body corporate approval is needed because the installation is entirely within your own kitchen. The cost is $3,300 fully installed, including the system, tap, all fittings, and testing.
Do I need body corporate approval to install a water filter in my apartment?
Not for an under-sink system. An under-sink reverse osmosis system connects to your private plumbing (the cold water supply and drain under your kitchen sink), so it does not involve any shared building infrastructure. Body corporate approval would only be needed if you wanted a whole-house filter on the building mains, which is typically not practical for individual apartment owners.
Can I install a water filter if I am renting an apartment?
You need your landlord’s permission because the installation involves connecting to the cold water supply under the sink and adding a dedicated drinking water tap. Many landlords approve this because it is a property improvement that adds value to the kitchen. If your landlord declines, a benchtop gravity filter is the best non-plumbed alternative, though it provides significantly lower filtration quality than a reverse osmosis system.
What is the best water filter for a Melbourne apartment?
An under-sink reverse osmosis system is the best option for apartment living. It removes up to 98% of contaminants, including chlorine, chloramine, heavy metals, fluoride, and dissolved solids. It fits under any standard kitchen sink, does not need body corporate approval, and costs $3,300 installed.
How much does a water filter cost for a Melbourne apartment?
An under-sink 7-stage reverse osmosis system costs $3,300 fully installed, including GST. This includes the complete system, a chrome drinking water tap, all plumbing connections, installation by a licensed plumber, and testing. Ongoing filter replacements cost approximately $150 to $200 per year and can be done yourself without a plumber. 0% interest finance is available for eligible customers.
Will a jug filter remove chloramine in my apartment?
No. Most jug filters use basic activated carbon, which removes chlorine but cannot effectively remove chloramine. If your apartment is in Melbourne’s western suburbs (supplied by Greater Western Water), your water contains chloramine rather than chlorine. You need a reverse osmosis system or a filter with catalytic or composite carbon to remove chloramine.
