Plan your salon floor
Area and service mix. Reception and back of house come off first.
Service floors planned around the bottleneck, not the chairs
How this calculator works
- Net service floor = area − back of house − reception.
- The service floor is split by mix: hair only puts everything into the hair zone; hair and beauty splits 60/40; unisex full service splits 50 hair, 25 beauty, 25 nails.
- Area per styling station = 45 + (40 ÷ chairs per wash point). At four chairs per wash that is 55 sq ft, because each station carries a quarter of a backwash.
- Stations = floor(hair zone ÷ area per station), and wash points = ceiling(stations ÷ chairs per wash point).
- Beauty rooms = floor(beauty zone ÷ 90 sq ft) and nail stations = floor(nail zone ÷ 35).
- Plumbing points = (wash points × 2) + beauty rooms + 1, and electrical load is estimated at 1.2 kW per station, 3 kW per wash point and 1.5 kW per beauty room, plus a 6 kW base.
| Element | Area | What it includes |
|---|---|---|
| Styling station | 45 sq ft | Chair, mirror bay, trolley, stylist circle |
| Wash point | 40 sq ft | Backwash unit, stylist standing space, trolley |
| Beauty / facial room | 90 sq ft | Couch with access on three sides, trolley, basin |
| Nail / pedicure station | 35 sq ft | Chair, technician stool, trolley |
| Reception and retail | 80 – 200 sq ft | Desk, waiting, product display |
| Back of house | 12 – 24% | Colour bar, laundry, staff, stores |
| Chairs per wash point | 3 – 5 | Three where colour dominates, five for dry styling |
Worked example — a 1,000 sq ft hair and beauty salon
| Step | Arithmetic | Result |
|---|---|---|
| Back of house at 18% | 1,000 × 0.18 | 180 sq ft |
| Reception and retail | as entered | 90 sq ft |
| Net service floor | 1,000 − 270 | 730 sq ft |
| Hair zone at 60% | 730 × 0.60 | 438 sq ft |
| Beauty zone at 40% | 730 × 0.40 | 292 sq ft |
| Area per station | 45 + (40 ÷ 4) | 55 sq ft |
| Styling stations | floor(438 ÷ 55) | 7 stations |
| Wash points | ceiling(7 ÷ 4) | 2 |
| Beauty rooms | floor(292 ÷ 90) | 3 |
The services are the hard part
A salon looks like a light fit-out and is not. Each wash point needs hot and cold supply, a dedicated waste with a hair trap that can actually be cleaned, and a water heater — and in a Mumbai high-street unit the existing plumbing usually supports one basin, not three backwashes. Confirm the incoming water line, the drainage stack position and the available electrical load before signing the lease, because retrofitting any of the three is expensive and sometimes impossible.
The electrical load catches people out too. Seven stations with dryers and stylers, two water heaters, air conditioning for a space full of heat-generating equipment, and a colour bar comes to 20 to 25 kW for a modest salon. An older building with a 10 kW sanctioned load will not carry it, and an upgrade application takes months.
Finally, ventilation. A colour bar and a nail station both release fumes that need extracting at source rather than diluting across the room. A dedicated exhaust over the colour bar and at each pedicure position is a few thousand rupees of ducting and it is the difference between a salon that smells professional and one that smells like a chemistry lab. Clients notice it within ten seconds of walking in.
Every constant on this page comes from Greenbox site records — measured drawings, signed BOQs and completion certificates from projects delivered between 2023 and 2026 — rounded to the figures an estimator would actually write down. We publish them so the arithmetic can be audited rather than trusted. Treat the output as a planning figure: accurate enough to brief a landlord, a bank or a family, and not accurate enough to sign a contract against.
What this tool does not cover
- Salon furniture and equipment, which for chairs, backwashes and a colour bar typically exceeds the base fit-out cost.
- Water heating capacity and the storage it needs.
- Statutory licensing and any local shops-and-establishments requirements.
- Accessibility, which needs a step-free route and at least one accessible washroom.
- Acoustic treatment. A hard-surfaced salon with seven dryers running is genuinely loud.
- For a general commercial fit-out rate, use the office interior cost calculator as a starting point and add equipment separately.

Frequently asked questions
How much space does a salon chair need?+
Forty-five square feet per styling station, covering the chair, the mirror bay, the trolley and the stylist's working circle. Chairs should be at least 5 ft 6 in apart centre to centre, or two stylists end up working back to back.
How many wash points does a salon need?+
One per four styling chairs for a standard salon, and one per three where colour work dominates. Under-providing backwash is the fastest way to create a Saturday bottleneck, because a colour client occupies a wash point far longer than a cut-and-blow-dry.
How big should a facial room be?+
About 90 square feet — a couch with access on three sides, a trolley, a basin and somewhere for the client to leave clothes. Below 80 sq ft the therapist cannot work around the head of the couch, which is where most of the work happens.
What electrical load does a salon need?+
Twenty to twenty-five kilowatts for a seven-station salon, once dryers, stylers, two water heaters, air conditioning and a colour bar are counted. An older Mumbai building with a 10 kW sanctioned load cannot carry it, and an upgrade takes months — check before signing.
Does a salon need special ventilation?+
Yes, at source. A colour bar and each pedicure position should have dedicated extraction rather than relying on the air conditioning to dilute fumes. It costs a few thousand rupees in ducting and it is the first thing a client notices when it is missing.
