Salon Renovation Cost Singapore (2026): Hair, Nail, Beauty and Spa Fit-Out Prices

By ifix.sg by Trends Interior Design Pte Ltd (UEN 200408913Z) · Last updated 5 Nov 2026 · Sources cited below

Short answer: Published 2026 Singapore guides put hair salon renovation at about S$60–S$180 per sq ft, nail and beauty salons at about S$70–S$140, and spas at about S$150–S$300+. Medi-spas with regulated treatments can reach S$400–S$700. Plumbing for wash basins, wet-area waterproofing and ventilation drive most of the cost.

How much does salon renovation cost in Singapore in 2026?

Salon renovation covers hair salons, barbers, nail bars, beauty and facial studios, and spas. Compared with an ordinary shop, a salon needs more plumbing, more power and more wet-area work. Wash basins, pedicure chairs, steam rooms and hair dryers all add to the M&E scope.

The ranges below come from publicly published Singapore guides. They are indicative ranges from other firms, not a ifix.sg quotation, and usually exclude GST and loose furniture.

One contractor publishes totals by salon size instead [4]:

The per-sq-ft figures vary widely between sources: hair salons run from S$60 [2] to S$180 [1]. Specification, mall rules and whether plumbing already exists explain much of the gap. Our price for your salon is quote on request.

How do you estimate a budget for your salon?

Multiply your floor area by a published range, then adjust for your scope. For example, using the published hair-salon bands, a 1,000 sq ft salon works out to about S$60,000–S$110,000 at S$60–S$110 per sq ft [2], or S$100,000–S$180,000 at S$100–S$180 per sq ft [1]. This is simple arithmetic on published figures, not a quote. Your number moves with:

• the number of wash basins, pedicure chairs and treatment rooms
• whether water, drainage and power points already exist where you need them
• mall or building rules, such as overnight work
• finish level and the amount of custom carpentry

What is usually included in a salon fit-out?

Published salon scopes typically include [1][2][4]:

• Shampoo basin plumbing, water heaters and drainage
• High-load electrical circuits, lighting and dimmers
• Mirror and styling stations, reception counter and product display
• Treatment rooms or cabins with acoustic partitions
• Waterproofing for wet areas, steam rooms and showers
• Flooring, ceilings, painting and signage

What makes salon renovation different?

Plumbing and hot water

Hair salons need shampoo basins with dedicated water and drainage routing, hot water from a storage or instant heater, and waterproofing [4]. Pedicure spas need plumbing too [2]. If the unit has no nearby water and drainage points, extending them is often the biggest single variable in a salon budget.

Wet areas and waterproofing

Steam rooms, showers and jacuzzis in spas require professional waterproofing and specialised M&E works [1]. Wet treatment rooms may include a ceiling shower or rain head [3]. Waterproofing must be right first time, because leaks into neighbouring units are expensive to fix.

Electrical load

Hair dryers and styling tools need high-load electrical circuits [2]. Ambient dimmers and colour-accurate lighting are common in beauty and nail studios [2]. Check the unit's power supply before you sign the lease.

Ventilation

Spas need good airflow for comfort and aromatherapy [1]. Salons also need ventilation for chemical odours from hair treatments; one reinstatement guide notes salons often install ventilation hoods [5].

Treatment rooms and acoustics

Spa and facial rooms need soundproofing, adjustable lighting and temperature control [1]. Acoustic treatment cabins are listed in beauty spa scopes [2]. For indicative partition prices, including acoustic options, see the partition wall cost guide [8].

Carpentry and front of house

Mirror stations, reception counters, product walls and storage are custom joinery. Reception and retail display are often the highest-margin square footage in a spa [3].

What approvals does a salon renovation need?

• Landlord or mall management. Expect a renovation permit, overnight work rules in malls, a risk assessment and method statement, and insurance [2].
• SCDF fire safety. Fire safety works, such as new layouts that affect escape routes or fire compartments, need SCDF plan approval unless exempt or lodged as minor works [6].
• MOH (medi-spas only). If you offer medical aesthetics such as injectables or lasers, the fit-out falls under MOH Healthcare Services Act scope [3]. See our clinic renovation cost guide.
• HDB shops. If your salon is in an HDB shop, HDB approval rules apply; see the HDB shop renovation cost guide.

How long does a salon renovation take?

Published timelines are 3–5 weeks for hair salons and barber studios and 4–6 weeks for beauty spas and nail studios [2]. Another contractor gives 4–6 weeks for a compact salon, 6–9 weeks for a standard salon and 9–12 weeks for a premium spa with multiple rooms [4]. Add time for landlord approval and any SCDF submission.

How can you reduce salon renovation cost?

• Choose a unit with water and drainage points near where the basins will go.
• Group wet areas together to shorten plumbing runs.
• Check the electrical supply before committing, so you don't need a costly upgrade.
• Hold a 10–15% contingency for unforeseen works, as one contractor recommends [1].
• Compare itemised quotes with plumbing, electrical and carpentry listed separately.
• Phase the premium items. Feature walls and premium finishes can often wait, while plumbing, waterproofing and electrical work must be done right the first time.
• Plan for the exit. Every basin, cabinet and hood you install now may need removing at lease end.

What will it cost to reinstate the salon at lease end?

Salons usually have more plumbing to cap and more finishes to make good than offices. One guide puts salon reinstatement at S$15–S$30 per sq ft for lightly fitted salons and S$30–S$45 for salons with built-in cabinetry, ventilation hoods and multiple basins. Specialist salons can exceed S$50 [5]. Most salon reinstatements take 2–4 weeks, and the guide recommends planning 6–8 weeks before lease expiry [5]. See our reinstatement cost Singapore guide for current commercial ranges [7].
