Laundry Plumbing Costs in Victoria for 2026

The laundry is one of the most neglected rooms in Victorian homes from a plumbing maintenance perspective, often operating with original taps, pipes, and drainage that have not been touched since the house was built or last renovated. In many of Melbourne's post-war brick veneer homes across the middle suburbs from Doncaster and Templestowe through to Oakleigh and Cheltenham, the laundry still has its original 1960s or 1970s galvanised steel supply pipes, brass bib taps with separate hot and cold handles, a freestanding concrete or stainless steel trough, and a floor drain that connects to the same sewer pipe as the bathroom and kitchen. These original laundry installations are functional but ageing, and the most common problems are seized or dripping taps that have not been serviced in decades, corroded supply pipes that restrict the water flow, slow-draining trough and floor wastes that have accumulated scale and detergent residue, and washing machine hose connections that are past their safe service life.

Victorian laundries vary enormously in size and configuration depending on the era and style of the home. The separate external laundries that were standard in Victorian and Edwardian homes across Melbourne's inner suburbs (Fitzroy, Carlton, Brunswick, Northcote, Hawthorn) were typically a small brick or timber outbuilding at the rear of the property, disconnected from the main house, with basic plumbing consisting of a concrete trough and a single cold tap. Many of these external laundries have been incorporated into the house during extensions and renovations, but some still exist in their original form in unrenovated properties. The internal laundries in homes built from the 1950s onwards are usually a dedicated room adjacent to the kitchen or bathroom, and in modern homes built across Melbourne's growth corridors from Tarneit to Clyde the laundry is integrated into the floor plan as a combined laundry and utility room with built-in cabinetry, a benchtop with undermount trough, and dedicated spaces for the washing machine and dryer.

The plumbing scope of a laundry renovation in a Victorian home ranges from a simple fixture upgrade (new taps and trough on the existing pipe positions) through to a comprehensive remodel that involves relocating the water supply and drainage to new positions, installing a floor waste where none existed, upgrading the pipe material from galvanised steel to copper or PEX, and connecting modern fixtures including a mixer tap, an integrated trough, and properly configured washing machine connections. The cost range of $1,500 to $5,000 or more for the plumbing component reflects this wide scope variation, and the homeowner should understand that the plumbing is often the most complex and costly trade component of a laundry renovation because the pipe modifications happen behind the walls and under the floor where the work is hidden but essential.

Washing Machine Connections

Connecting a washing machine to the laundry plumbing costs $150 to $350 for a straightforward installation where the hot and cold supply taps, the drain connection, and the power outlet are already in place. The plumber connects the washing machine inlet hoses to the dedicated washing machine taps (which should be quarter-turn lever taps or mini stop valves that can be turned off when the machine is not in use), and connects the drain hose to the trough waste, a dedicated standpipe, or the floor waste drain. Most modern washing machines sold in Australia are cold-fill only (the machine heats its own water internally), which means only one water supply connection is needed, but many Victorian laundries still have dual hot and cold washing machine taps from an era when top-loading washing machines used the household hot water supply.

For a first-time washing machine installation in a laundry that does not have dedicated machine connections (which can occur in older Victorian apartments, granny flats, and very old houses where the washing was historically done by hand in the trough), the plumber needs to install the supply taps, run the drain connection, and possibly modify the drainage to accommodate the machine's high-volume pump discharge. This additional work costs $300 to $700 depending on the pipe routing distance and whether the laundry has accessible plumbing runs (timber subfloor) or requires modifications through a concrete slab. The washing machine brands most commonly installed in Victorian homes include Samsung, LG, Bosch, Miele, Fisher and Paykel, Electrolux, and Speed Queen, and while the plumbing connections are standardised across brands, the drain pump flow rate varies and the plumber should ensure the drain connection can handle the discharge volume without backflow.

The flexible braided inlet hoses that connect the washing machine to the water supply taps are one of the highest-risk components in a Victorian home for water damage. These hoses are under constant mains pressure (even when the washing machine is not running, if the supply taps are left open), and the rubber inner tube deteriorates over time until it ruptures, releasing a full-pressure water flow into the laundry. A burst washing machine inlet hose can deliver 1,500 litres per hour, and because many Victorian laundries do not have a floor waste drain, the water floods the laundry floor, flows into adjacent rooms, and causes extensive damage to flooring, walls, and contents before the leak is discovered. The prevention strategy is simple: replace the inlet hoses every five years with stainless steel braided hoses, and turn the supply taps off at the wall when the washing machine is not in use. This advice is consistent with the flexible hose replacement guidance in our leaking tap repairs guide and our water leak detection guide. Australian insurers frequently identify burst washing machine hoses as one of the top three causes of preventable water damage claims in residential properties, and many insurers now recommend that homeowners replace hoses proactively rather than waiting for visible signs of deterioration.

Laundry Tap Replacement

Laundry taps in Victorian homes are among the oldest and most heavily used taps in the house, and in many properties the laundry taps have been in service for 40 to 60 years without any maintenance or replacement. The original brass bib taps installed in Melbourne's post-war homes from the 1950s through the 1970s were built to last mechanically, but the washers have hardened, the spindles have corroded, and the chrome plating has deteriorated to the point where the taps are stiff, dripping, or both. Replacing old laundry taps costs $200 to $500 for a pair of new taps installed, with the cost depending on the tap style (separate hot and cold bib taps, a wall-mounted washing machine tap set, or a laundry mixer tap), the brand, and whether the existing pipe connections are compatible with the new taps or require adapter fittings.

The laundry tap configuration in a modern Victorian laundry typically includes a pair of quarter-turn washing machine taps (sometimes called mini stop valves or washing machine cocks) that provide the water supply to the washing machine, and a mixer tap or a pair of bib taps that supply the trough. The washing machine taps should be quarter-turn lever type so they can be easily turned off after each wash cycle, which eliminates the constant pressure on the washing machine inlet hoses and reduces the risk of a hose burst. The trough taps may be a wall-mounted laundry mixer (which combines hot and cold in a single body with a swivel spout) or separate hot and cold bib taps. Brands commonly used for laundry taps in Victoria include Caroma, Methven, Clark, and Oliveri for the mid-range, and Grohe and Hansgrohe for premium laundry fixtures. Our leaking tap repairs guide covers the repair versus replacement decision for all tap types in detail.

Laundry Trough Installation and Replacement

The laundry trough (also called a laundry tub or laundry sink) is a larger and deeper basin than a kitchen or bathroom sink, designed for soaking, handwashing, and pre-treating clothes before they go into the washing machine, as well as general utility use including cleaning tools, washing shoes, and filling buckets. Replacing a laundry trough costs $300 to $700 for the plumbing component (not including the trough itself if supplied by the homeowner), and the cost depends on whether the new trough fits in the same position with the same waste and water connections as the old one, or whether modifications are needed to the waste pipe and supply positions.

Laundry troughs in Victorian homes span several generations of design and material. The oldest troughs are the heavy concrete or cement troughs found in unrenovated homes from the pre-war and early post-war era, which are incredibly durable but stained, chipped, and visually outdated. Stainless steel troughs from brands like Clark and Everhard replaced the concrete troughs from the 1970s onwards and remain the most common trough type in established Victorian homes. Modern laundry troughs are typically polyurethane or acrylic (lighter and easier to install), with integrated cabinet bases that provide storage underneath and a benchtop surface alongside for folding and sorting. The Clark range (now part of the GWA Group alongside Caroma) dominates the Victorian laundry trough market, with their stainless steel and polyurethane troughs stocked at Reece, Tradelink, Bunnings, and the appliance retailers across Melbourne and regional Victoria.

Undermount and integrated troughs that sit below a stone or solid surface benchtop have become popular in modern Victorian laundry designs, following the same trend as undermount kitchen sinks. These require the same coordination between the plumber, the cabinet maker, and the stone mason as described in our kitchen plumbing guide for undermount kitchen sinks: the plumber positions the trough and makes the temporary connections, the stone mason templates and installs the benchtop, and the plumber returns for the final waste and water connections. This two-visit approach adds to the plumbing cost but ensures a precise fit between the trough and the stone.

Blocked Laundry Drains

Blocked laundry drains are a common problem in Victorian homes because the laundry drain carries a high load of lint, detergent residue, fabric softener, and other suspended solids from the washing machine discharge, and these materials accumulate in the drain pipe over time, gradually restricting the flow until the drain blocks completely. The washing machine discharge pump pushes the dirty water out at a high flow rate (approximately 20 to 40 litres per minute), and if the drain pipe cannot handle this flow rate due to a partial blockage, the water backs up and floods the laundry floor or overflows from the trough. Clearing a blocked laundry drain costs $150 to $400 depending on the blockage severity and the method required.

The most effective method for clearing a laundry drain blockage is high-pressure water jetting, which uses a thin, flexible hose with a specialised nozzle that propels water forward at high pressure to break up the blockage and scour the pipe walls clean of accumulated detergent and lint residue. The jetting clears not just the immediate blockage but also the partial build-up further along the pipe that would otherwise cause a recurrence within months. For persistent laundry drain blockages that recur despite jetting, the plumber should inspect the drain pipe with a CCTV camera to identify structural issues (cracked pipes, displaced joints, root intrusion) that are trapping debris and creating chronic blockage points. Our pipe relining and drain repairs guide covers the CCTV inspection and relining options for damaged drain pipes.

In Melbourne's older suburbs where the house drains are earthenware (terracotta), the laundry drain may share a common pipe run with the bathroom and kitchen drains, and a blockage in the shared section affects all three rooms. Tree root intrusion through the earthenware pipe joints is a common cause of shared drain blockages in suburbs with mature street trees and garden trees, particularly in Camberwell, Kew, Canterbury, Hawthorn, and Malvern where the large established gardens and avenues of elms, oaks, and planes provide extensive root systems that aggressively seek out the moisture leaking from old pipe joints. A root-related drain blockage requires jetting to clear the roots, CCTV to assess the pipe condition, and potentially pipe relining to seal the joints and prevent root re-entry.

Laundry Flood Prevention

The laundry is one of the highest-risk rooms in a Victorian home for water damage from burst hoses and overflowing fixtures, and the consequences are amplified because many Victorian laundries are located adjacent to bedrooms, living rooms, or on upper floors where the water flows through the floor into the room below. The floor waste drain is the primary defence against laundry flooding, providing a drainage point in the floor that captures overflow water before it spreads to adjacent rooms. Modern building standards require a floor waste drain in any room that contains a water-using appliance, but many older Victorian laundries were built before this requirement was introduced and do not have a floor waste, which means that any overflow or burst hose floods the laundry and adjacent rooms with no controlled drainage.

Installing a floor waste drain in an existing laundry costs $300 to $600 for a laundry on a timber subfloor (where the plumber can access the underside of the floor to connect the waste pipe) and $500 to $1,200 for a laundry on a concrete slab (where the slab must be cut to install the drain and connect it to the existing drainage). The floor waste should be positioned near the washing machine and the trough, which are the two most likely sources of overflow. In addition to the floor waste, the other flood prevention measures for a Victorian laundry include turning off the washing machine supply taps after each use, replacing the flexible inlet hoses every five years, ensuring the drain hose is securely connected to the standpipe or trough with no risk of it pulling loose during the pump cycle, and installing a washing machine leak detector (a small electronic device that sits on the floor behind the machine and sounds an alarm if water is detected, costing $30 to $80 from hardware stores).

For Victorian homeowners whose laundry is on the upper level of a two-storey home or townhouse, flood prevention is especially critical because water from an upper-level laundry flood flows through the ceiling into the rooms below, damaging the ceiling plasterboard, the cornice, the wall linings, the flooring, and any furniture and contents in the room below. The emergency plumber guide covers the urgent response process for laundry floods and burst hose emergencies, and the water leak detection guide covers the diagnostic approach for hidden leaks from laundry plumbing.

Full Laundry Renovation Plumbing

A full laundry renovation plumbing scope encompasses removing the existing fixtures and connections, upgrading the water supply pipes (replacing galvanised steel or corroded copper with new copper or PEX), modifying the drainage to suit the new layout, installing a floor waste drain (if not already present), and connecting the new fixtures including the trough, taps, washing machine, and any additional items such as a dryer condensate drain or a mop sink. The rough-in phase (running pipes to the new positions) happens after demolition and before the new cabinetry is installed, and the fit-off phase (connecting the fixtures) happens after the cabinetry and benchtop are in place. The total plumbing cost for a laundry renovation ranges from $1,500 to $5,000 depending on the scope.

Laundry renovations in Melbourne's inner suburbs present specific challenges related to the age of the existing plumbing. In the terraces and cottages of Fitzroy, Carlton, Collingwood, and Richmond, the laundry may have original lead waste pipes, galvanised steel water supply pipes, and a direct connection to an ageing earthenware sewer pipe that runs under the house. The plumber should assess the condition of these pipes during the renovation planning and include any necessary pipe replacement in the scope, because discovering corroded or collapsed pipes during the renovation creates delays and additional cost. In the post-war homes across Doncaster, Box Hill, Bentleigh, and Reservoir, the laundry plumbing is typically copper water supply and PVC drainage, which is in better condition but may still need upgrading at the fixture connections where the original brass fittings have corroded.

In homes across Melbourne's growth corridors (Tarneit, Point Cook, Craigieburn, Clyde, Officer), the laundries were built with modern PEX water supply and PVC drainage, but the builder-grade fixtures and cabinetry are often the first things homeowners want to upgrade. The plumbing modifications for a laundry renovation in a growth corridor home are typically less extensive than in an older home because the existing pipe infrastructure is in good condition and the main changes involve repositioning the fixture connections to suit the new cabinetry layout. Coordinating the laundry renovation with a bathroom renovation or kitchen renovation in the same project allows the plumber to handle both scopes in a single engagement, reducing the total number of site visits and providing a combined quote.

Greywater and Water Recycling

The laundry is one of the primary greywater sources in a Victorian home, producing approximately 100 to 150 litres of lightly contaminated water per wash cycle that can be diverted to the garden for irrigation rather than flowing to the sewer. Victorian homeowners have the option of installing a greywater diversion system that redirects the washing machine discharge to subsurface garden irrigation, subject to the requirements of the EPA Victoria guidelines and the relevant council regulations. A basic greywater diversion valve installed on the laundry drain costs $300 to $600 and allows the homeowner to switch between sending the greywater to the sewer (for loads with bleach or harsh chemicals) and diverting it to the garden (for loads with garden-friendly detergent). Our greywater system installation and maintenance guide covers the full range of greywater options, from simple diversion valves to comprehensive treatment and reuse systems.

For homes with a rainwater tank, the laundry is one of the permitted connections for rainwater supply in Victoria, meaning the washing machine can be plumbed to use rainwater rather than mains water. This requires a dedicated rainwater supply pipe from the tank to the laundry, a pump to provide adequate pressure, and a mains water backup connection that automatically switches to mains supply when the tank is empty. The plumbing for a rainwater-to-laundry connection costs $500 to $1,500 depending on the distance from the tank to the laundry and whether the pump and pipework are already partially installed. Using rainwater for laundry reduces the household mains water consumption by approximately 40,000 to 60,000 litres per year for a family of four, which at Melbourne's current water prices saves $120 to $230 per year.

Regional Laundry Plumbing Costs Across Victoria

Laundry plumbing costs across Victoria follow the same regional pricing patterns as other plumbing services, with Melbourne's inner and middle suburbs offering the most competitive pricing due to the high density of plumbing businesses and short travel distances. A standard laundry tap replacement in inner Melbourne costs $200 to $400, and a full laundry renovation plumbing scope costs $1,500 to $4,000. The inner suburbs have the oldest laundry plumbing infrastructure and the highest proportion of laundries that need upgrading, which drives steady demand for laundry renovation work. In the terraces and cottages of Fitzroy, Brunswick, and Northcote, the laundry is often a small room at the rear of the ground floor that was added during the mid-twentieth century conversion from an external washhouse, and the plumbing reflects this incremental approach with a mix of pipe materials and connection styles that have accumulated over successive modifications. The weatherboard and brick veneer homes of Kew, Camberwell, and Hawthorn typically have larger dedicated laundry rooms with more conventional plumbing layouts, but the copper and galvanised pipes in these 1940s to 1960s homes are now 60 to 80 years old and approaching or past their reliable service life.

Melbourne's growth corridor suburbs from Tarneit and Werribee through to Craigieburn, Mickleham, and Clyde have newer laundry plumbing infrastructure built with PEX supply and PVC drainage, and the most common laundry plumbing requests are washing machine connections, tap upgrades from builder-grade fixtures, and trough replacements where the original polymer trough has cracked or stained. The slab-on-ground construction in these homes means that any drainage modifications (such as adding a floor waste or relocating the trough waste) require sawcutting the slab, which adds to the renovation cost compared to the subfloor access available in older timber-framed homes.

Geelong's laundry plumbing market is well-served and the pricing is comparable to Melbourne's middle suburbs. Ballarat and Bendigo have capable plumbers who handle the full range of laundry plumbing work, and the regional supply network provides good access to the standard trough and tap brands. The Mornington Peninsula has a particular demand for laundry upgrades in holiday homes where the original laundry was a basic external lean-to with a concrete trough and a single tap, and the homeowner wants to create a modern internal laundry as part of a broader home upgrade. Rural Victorian properties may have specific laundry plumbing requirements related to bore water or tank water supply, which affects the plumbing configuration and may require additional filtration to protect the washing machine from sediment and mineral content in the water. For properties on rainwater tank supply, the tank water quality is generally suitable for laundry use without treatment, but sediment from the tank should be filtered before it reaches the washing machine to prevent damage to the inlet valve and pump.

Consumer Protection and Standards

Laundry plumbing work in Victoria that involves connecting or disconnecting fixtures from the water supply or drainage must be performed by a licensed plumber who holds a current licence or registration from the Building and Plumbing Commission. The plumber must issue a compliance certificate within five business days of completing regulated work. Greywater diversion installations must comply with the EPA Victoria guidelines and the local council requirements, and the plumber should confirm the regulatory requirements before commencing the installation. The Consumer Affairs Victoria provides consumer guarantees for plumbing services, and the Victorian Civil and Administrative Tribunal provides dispute resolution for plumbing work that is defective or not completed as agreed. The EPA Victoria website provides the regulatory framework for greywater use in Victoria.

Rental Property Laundry Plumbing

Laundry plumbing repairs in Victorian rental properties are the landlord's responsibility under the Residential Tenancies Act 1997. A burst washing machine hose or a blocked laundry drain that causes flooding is an urgent repair requiring response within 24 hours. A dripping laundry tap or a slow-draining trough is a non-urgent repair that the landlord must address within 14 days. Property managers should include the laundry taps, hose connections, and floor waste in the routine maintenance inspection checklist, and should arrange preventive replacement of the washing machine hoses every five years to avoid the catastrophic water damage that a burst hose causes in a tenanted property. For hot water system issues that affect the laundry hot water supply, the same urgent repair timeframes apply.

Coordination with Other Plumbing Work

The laundry plumbing shares water supply and drainage connections with other rooms in the house, and coordinating laundry work with other plumbing projects saves time and money. In many Victorian homes the laundry is adjacent to the bathroom and shares a common hot water run from the hot water system, so a hot water system repair or replacement affects the laundry supply as well. The laundry drain typically connects to the same sewer pipe as the bathroom drain, which means a toilet blockage investigation may reveal shared drainage issues that affect the laundry as well. If the laundry renovation is part of a broader home renovation, the plumber can coordinate the laundry rough-in and fit-off with the bathroom and kitchen plumbing scopes, providing a single engagement that covers all three rooms.

What to Look Out For in Laundry Plumbing Quotes

A laundry plumbing quote should itemise each fixture connection separately (trough, taps, washing machine, floor waste), specify whether the plumber is supplying the fixtures or the homeowner is providing them, and detail any pipe upgrade or modification work including the pipe material, the approximate route, and the reason for the modification. For a laundry renovation, the quote should specify whether the scope includes the rough-in and fit-off as separate visits, whether the compliance certificate is included, and whether the existing pipe condition has been assessed (particularly in older homes where the galvanised pipes may need replacement).

Ask the plumber whether they have inspected the condition of the existing laundry pipes and whether any pipe replacement is included in or excluded from the quote, because discovering corroded pipes during the renovation adds cost that should ideally be anticipated in the original quote. Ask whether the quote includes a floor waste installation if the laundry does not currently have one, because the floor waste is a critical flood protection measure. Post your laundry plumbing project on The Quote Yard to connect with licensed plumbers across Victoria.
