Dental Fitout Cost Calculator
Estimate the cost of a dental practice fitout in Australia, including chairs, plant room, compressor and suction, OPG imaging and the sterilisation suite.
Includes the chair unit, surgery joinery, services reticulation and the room build.
The plant room is the piece most first time practice owners underestimate. Compressor and suction generate heat and noise, so the room needs mechanical exhaust, acoustic treatment and enough clearance for servicing. Locating it against a shared wall with a consult room or a neighbouring tenancy causes complaints you cannot fix cheaply.
Converting retail or office to dental is a change of use requiring a development application, and dental adds a specific trap. Suction and compressor plant, plus the amalgam separator required for waste, mean trade waste approval from the water authority, which is a separate application from council and is regularly forgotten until the plumber asks for it.
Reticulate services to more chairs than you install on day one. Running the extra compressed air, suction, water, waste, power and data to a fourth and fifth surgery while the walls are open costs a few thousand dollars. Doing it later means demolishing finished rooms and closing the practice for a week.
Dental chairs are the most negotiable line in the project. List price is rarely the transaction price, and manufacturers discount hardest at the end of their financial year and around trade congresses. Buying three or four units at once, or bundling imaging with chairs, moves the number more than anything you can do on the building side.
💰 Ways to save
- Buy an existing practice fitout rather than building one. A trading practice already carries the plant room, the reticulated air and suction, the sterilisation suite, the shielded imaging room, the trade waste approval and the approved use, and it usually comes with a patient list attached. Refitting an existing dental tenancy typically runs 45 to 60 percent of a conversion from retail, and it removes the two longest schedule risks, which are the change of use approval and the radiation licence.
- Rough in the services for future surgeries during the first build. Compressed air, suction, water, waste, power and data run to an unbuilt fourth and fifth surgery cost roughly $4,000 to $8,000 per position while the ceilings and walls are open. Retrofitting the same services later means demolishing finished joinery, closing the surgery for a week and losing the revenue, which is routinely a $30,000 swing per chair.
- Separate the equipment purchase from the building contract and negotiate it directly with the manufacturer. Chairs, imaging, autoclaves and the compressor all carry manufacturer finance and are heavily discounted at end of financial year and around trade congresses. A builder supplying the same equipment adds 10 to 20 percent. Keep the builder accountable for services, floor loading and the plant room, and buy the clinical equipment yourself.
- Design the sterilisation suite and plant room before you design the reception. Both have hard functional constraints, on workflow direction for sterilisation and on noise, heat and servicing access for plant, and both must sit in specific relationships to the surgeries. Practices that lay out the front of house first almost always end up with a compromised steri room or a compressor against a patient facing wall, and fixing either after construction is a full re fitout of that zone.

Understanding dental fitout costs in Australia
What a dental fitout costs in 2026
Dental is the most services intensive fitout in primary healthcare, and the 2026 Australian numbers reflect that. A conversion of retail or office space to a three chair practice typically costs $450,000 to $750,000 for the build and services, or roughly $2,800 to $4,200 per square metre. Add the clinical equipment and the total commonly reaches $650,000 to $1,100,000. On a per chair basis, which is how the industry actually thinks about it, a fully delivered surgery including the chair unit, the room build, joinery, reticulated services and a share of the plant costs about $110,000 to $180,000. Taking over an existing dental tenancy is dramatically cheaper, often $180,000 to $350,000 to refresh three surgeries, because the expensive infrastructure is already in the walls.
Chairs and surgeries, the real unit of cost
Floor area matters less in dental than surgery count. Each surgery needs compressed air, dental suction, water, waste, power, data, an X ray point, task lighting, a scrub basin, custom joinery to suit the chair's delivery system, and impervious flooring coved to the wall. The dental chair unit itself ranges enormously, from around $25,000 for an entry level unit to $70,000 or more for a premium chair with integrated imaging, cameras and an ergonomic delivery system. The room build and services around it add another $45,000 to $80,000. That is why the sensible way to budget a dental practice is per chair, then check it against a per square metre sanity test rather than the other way round.
The plant room, compressor and suction
Every practice needs a plant room housing the compressor, the suction motor, the water treatment and often the reverse osmosis and vacuum systems. This room is the source of most post opening complaints. Compressors and suction motors are loud and produce significant heat, so the room needs mechanical exhaust, acoustic lining, and clear service access on all sides of the plant. It should be sized for the chair count you plan to reach, not the count you open with, because upgrading a compressor later means opening up the room and reworking the reticulation. A properly built plant room including the compressor, suction, acoustic treatment and exhaust typically costs $45,000 to $75,000. Never locate it against a wall shared with a surgery, a consult room or a neighbouring tenancy.
Sterilisation and infection control
Dental sterilisation is regulated to AS/NZS 4187 and is scrutinised heavily by state health regulators and by the Dental Board's infection control expectations. The suite needs a strictly one directional layout, moving from a dirty receiving zone through ultrasonic cleaning and rinsing, to a drying and packaging zone, into the autoclave, and finally into clean sterile storage, with no backtracking and no through traffic. It needs a dedicated hand basin separate from the instrument sinks, mechanical exhaust, impervious benching with sealed joints, and a class B autoclave with cycle logging. A compliant suite typically costs $55,000 to $95,000. Because the workflow is directional, the room's position and shape dictate the whole floor plan and must be locked in the first layout.
Imaging, radiation licensing and trade waste
Most practices install intraoral X ray at each surgery plus a central OPG, and increasingly a CBCT. Every one of those is a radiation apparatus that must be registered with the state radiation health authority, and the room housing an OPG or CBCT needs a shielding assessment by a qualified expert, a compliant door, a leaded viewing panel and a controlled entry. Budget $70,000 to $110,000 for an OPG room including the machine, shielding and approvals, and materially more for CBCT. The other approval that catches new owners is trade waste. Dental practices must install an amalgam separator and hold a trade waste agreement with the local water authority, which is a separate application from council consent and takes several weeks. Your plumber cannot connect the practice without it.
Approvals, timelines and the cost of waiting
Converting a retail or office tenancy to dental is a change of use requiring a development application in every Australian state, typically eight to twenty weeks, and parking ratios are again the usual sticking point. Running in parallel you have the trade waste application and, once the rooms are built, the radiation licensing. On site construction for a three to four chair practice runs twelve to twenty weeks, with the plant room, reticulation and steri suite driving the programme rather than the finishes. Realistically a conversion is a nine to fifteen month project from first sketch to first patient. The financial risk in that timeline is rent. Negotiate a rent free or half rent fitout period covering approval and construction, because six months of full rent on a shell that cannot treat patients can easily be $60,000 to $120,000 of pure loss.
What sits outside the builder's contract
The construction contract does not include the things that make the practice work. Clinical equipment beyond the chairs, meaning autoclaves, ultrasonic cleaners, curing lights, handpieces, an intraoral scanner and instruments, commonly adds $80,000 to $200,000. Practice management software, servers, workstations and the digital imaging integration add $30,000 to $70,000. Professional fees for a dental fitout designer, town planner, building surveyor, radiation consultant and project manager typically run 10 to 15 percent of construction. Signage, furniture, sterile stock and working capital for the first six months add more. Hold a 12 to 15 percent contingency on any conversion, because the ceiling space in an old retail tenancy never matches the drawing and the reticulation has to go somewhere.
Frequently asked questions
How much does a dental fitout cost in Australia in 2026?
Converting retail or office space to a three chair practice typically costs $450,000 to $750,000 for the build and services, roughly $2,800 to $4,200 per square metre, and $650,000 to $1,100,000 once clinical equipment is added. Refitting an existing dental tenancy is far cheaper at around $180,000 to $350,000 for three surgeries, because the plant, reticulation, steri suite and approvals already exist.
What does one dental surgery cost to build?
About $110,000 to $180,000 fully delivered, including the chair unit, room build, joinery, reticulated services and a share of the plant. The chair unit alone ranges from around $25,000 for an entry level model to $70,000 plus for a premium unit with integrated imaging and cameras, with the room and services adding another $45,000 to $80,000. Budget per chair first, then sanity check against a per square metre rate.
How much does the plant room, compressor and suction cost?
Typically $45,000 to $75,000 including the compressor, suction motor, acoustic lining, mechanical exhaust and service clearances. Size it for the chair count you plan to reach rather than the count you open with, because upgrading later means reworking the reticulation. Never put the plant room against a wall shared with a surgery or a neighbouring tenancy, since compressor noise and heat generate complaints that cannot be fixed cheaply.
Do I need approvals beyond council consent for a dental practice?
Yes, three separate ones. Council gives you the change of use development consent, typically eight to twenty weeks. The state radiation health authority must register every X ray apparatus and will require a shielding assessment for an OPG or CBCT room, which takes six to twelve weeks. The local water authority must issue a trade waste agreement covering the amalgam separator, and your plumber cannot legally connect the practice without it.
Should I rough in services for surgeries I am not building yet?
Almost always yes. Running compressed air, suction, water, waste, power and data to an unbuilt surgery costs roughly $4,000 to $8,000 per position while the walls and ceilings are open. Doing the same work later means demolishing finished joinery, closing that part of the practice for about a week and losing the revenue, which typically turns into a $30,000 swing per chair.
How long does a dental fitout take from lease to opening?
Nine to fifteen months for a conversion. Allow six to ten weeks for design, eight to twenty weeks for the development application, several weeks for trade waste, twelve to twenty weeks on site, then radiation licensing once the rooms exist. Negotiate a rent free or half rent fitout period covering the approval and construction window, because full rent on a non trading shell for six months can be $60,000 to $120,000 of dead cost.
