Kitchen Benchtop Replacement: The Ultimate Step-by-Step Guide

If your current benchtop is damaged, stained, or no longer matches the rest of your home, a replacement may be the most practical next step. The process is more detailed than it may appear from the outside, which is why understanding each stage helps set the right expectations. From templating and fabrication to removal, installation, and reconnection, every step matters.
At Master Tops, we design, manufacture, and install stone kitchen benchtops for Perth homeowners looking for a smarter upgrade without the disruption of a full renovation. So, being experts, we are going to explain how professional kitchen benchtop replacement works and how long it usually takes. So let’s begin.
The Kitchen Benchtop Replacement Process: Step by Step
Step 1: Professional Design and Digital Templating
Every good benchtop replacement starts with proper measurement. This is the step that decides whether the end product will be tight, match up correctly, and be smooth once installed.
After you choose your chosen material and style, a technician visits the premises to take a full digital template of the current cabinetry and room arrangement. Laser templates and computer measurement devices are now standard practice on current projects and are significantly more accurate than human measurement methods.
This stage captures important details such as:
Sink and cooktop positions
Splashback heights
Corner angles
Overhangs and edge details
Appliance clearances
Waterfall end requirements
Seam and join locations
If you are planning an undermount sink, this is also the stage where the sink is often collected or confirmed so the fabricator can integrate it properly during manufacturing.
Step 2: In-House Manufacturing and Craftsmanship
Once the measurements are agreed upon, the workbench goes into fabrication. This is where the slab is cut, shaped, completed and staged for installation.
Most quality benchtops are produced in a specialist workshop using precision machinery. This allows the crew to achieve a high grade of cut-outs, edge profiles, mitred joins and polishing before it arrives at your home.
During fabrication, our team completes:
Sink cut-outs
Cooktop cut-outs
Tap holes
Edge profiling
Waterfall edges
Mitred corners and joins
Polishing and finishing
Factory fitting of sinks where required
It can take a long time, depending on the material. Porcelain, sintered stone, granite and marble can take longer to make as they require more specialised handling and finishing, but laminate benchtops are normally made faster.
Stone items will take approx. 10 to 15 business days to fabricate, but more sophisticated jobs may take longer, depending on the availability of the slabs, the complexity of the design and the workload at the workshop.
Step 3: Preparing Plumbing, Electrical, and Appliance Connections
Before the old benchtop comes out, the kitchen must be made safe for removal and installation.
This often involves disconnecting:
Sinks and tapware
Dishwashers
Gas cooktops
Electric cooktops
Nearby appliances
Electrical fittings and services
Plumbing work in WA generally requires a licensed plumber or permit holder, except for limited exemptions. Some benchtop suppliers coordinate these trades, while in other cases, the homeowner may need to book them separately.
This part of the process may seem simple, but it is essential. Correct disconnection protects the rest of the kitchen and helps prevent delays when the new benchtop is ready to go in.
Step 4: Safe Removal and Substrate Levelling
Once services are disconnected, the old benchtop can be removed.
The skilled removal team will carefully take the current top away from the cabinetry, avoiding damage to the cabinet carcasses underneath, and delicately separate silicone joints. If the cabinets are still physically intact, in many cases, they can be reused.
The substrate is inspected after removal. That means the team checks the tops of the cabinets to make sure the new benchtop will be flat and secure.
If the cabinets have shifted, sagged or settled over time, they may need to be re-levelled or reinforced before installation. This is especially critical with heavier materials like stone, which can add a fair amount of weight to the base cabinetry.
Step 5: Precision Installation and Seamless Joining
Installation day is where the project really comes together.
The new sections are hauled into the kitchen and set gingerly on the cupboards. These materials are often hefty and brittle at the edges; thus, installation needs to be undertaken with care and experience.
During installation, the team will typically:
Check levels and alignment
Secure the benchtop in place
Fit and seal joins
Install the waterfall ends where required
Apply adhesives and silicone
Make fine adjustments on site
Larger kitchens might need more than one slab part. The aim is always to minimise visible joints, although some are inevitable because of slab sizes and room layout. A good installer will make these joints where they are least visible and finish them as neatly as possible.
This is also the stage where any final shaping or polishing may be done on site to ensure the completed result looks polished and consistent.
Step 6: Final Trade Reconnections and Post-Care
Once the benchtop is secured, the trades return to reconnect the kitchen services.
This may include:
Re-installing sinks
Reconnecting tapware
Fitting dishwashers back in place
Reconnecting cooktops
Checking gas lines
Testing electrical connections
Cleaning and sealing final joints
At this step, silicone is normally used along the joining lines and around the washbasin areas. The kitchen can ordinarily be utilised only after some time of curing.
Homeowners also receive care advice based on the selected surface. Even the most durable materials may be aided with the correct cleaning products and basic maintenance routines. Starting with the right procedure helps keep the benchtop looking and working great over time.
How Long Does Kitchen Benchtop Replacement Take?
The installation itself is usually fast, but the full project takes longer because templating, fabrication, and trade coordination all need to happen in sequence.
As a general guide, the full process from first site visit to final handover may take around 2 to 6 weeks.
Typical timing can look like this:
Stage | Time |
Consultation and quote | 1–3 days |
Digital templating | 1 day |
Fabrication | 1–4 weeks, depending on the material |
Removal and installation | 1 day |
Trade reconnections | Same day or next day |
If you are planning a restoration around a specific event or deadline, it is worth starting early so you have time for measuring, fabrication and trade booking without rushing.
How Much Does Kitchen Benchtop Replacement Cost in Perth?
The cost of replacing a kitchen benchtop depends on several factors, including the material you choose, the size of the kitchen, the number of cut-outs, the edge profile, and whether extra trades are required.
In Perth, homeowners may pay a little more than the national average in some cases due to freight, material sourcing, and the realities of the WA market. For that reason, it is smart to budget with a buffer rather than looking only at the lowest quote.
As a broad guide, installed pricing may look like this:
Material | Approximate Installation Cost |
Laminate | $1,500–$5,000 |
Timber | $3,500–$7,000 |
Porcelain | $7,000–$15,000 |
Sintered Stone | $4,500–$7,500 |
$7,000–$20,000 |
These figures generally include supply, fabrication, and installation. However, there are often extra costs to factor in, such as:
Removal of the old benchtop
Plumbing reconnections
Electrical reconnections
Gas fitting
Sink and tap upgrades
Waterfall ends
Extra cut-outs
Complex cabinetry adjustments
Removal and trade work can add a noticeable amount to the total project, so it is always better to ask for a full scope before committing to a final quote.

FAQs
How long does a kitchen benchtop replacement take?
Most projects take around 2 to 6 weeks from templating to final installation, depending on the material and complexity.
Can I keep my existing cabinets?
Yes, in many cases, existing cabinets can be reused if they are structurally sound and properly levelled before installation.
What is the best material for a kitchen benchtop?
It depends on your budget, cooking habits, and style preferences. Porcelain, sintered stone, granite, laminate, and timber all suit different needs.
Do I need a plumber and an electrician?
Yes, if sinks, cooktops, or electrical fittings need to be disconnected or reconnected, licensed trades should handle the work.
Is it possible to replace only the benchtop and not the whole kitchen?
Absolutely. Many homeowners choose to replace only the benchtop when the cabinets are still in good condition, and they want a faster, more affordable upgrade.
