Two numbers, not one — the machine you buy once, and the fragrance that comes back every month
The cost of scenting a home is a one-off hardware figure plus a small monthly fragrance figure. Almost every quote you see is only the first one.
The short version
Start here
Hardware, once: one Sukoon ₹1,899 for a studio, two at ₹3,798 for a 2BHK, three at ₹5,697 for a 3BHK, four at ₹7,596 for a 4BHK.
The one-off number
Sukoon ₹1,899 each
Fragrance is roughly ₹6 per millilitre in a 300ml bottle at ₹1,799. At four drops a tank, one machine used daily gets through about 6ml a month.
The recurring number
300ml ₹1,799
That works out at about ₹36 a month per machine — ₹108 a month for a fully scented three-machine home. The refill bill is the small half of this.

Year one for a 2BHK: ₹3,798 of hardware plus ₹864 of fragrance, or about ₹389 a month. Year two onward is ₹72 a month, because the machines are already bought.

Founder Diaries · Home Scenting by Home Type
By Sonal Sahani · ISIPCA Versailles 10 min read Updated August 2026
Ask what it costs to scent a home and you get handed a single figure, which is the wrong shape of answer. Scenting a home is two purchases that behave completely differently: hardware you buy once and fragrance you buy again. The hardware is the large number, and it never comes back. The fragrance is the small number, and it comes back forever. Most people brace for the second one and it turns out to be about the price of a coffee a month.
Quick answers — read this first
Hardware, once: one Sukoon ₹1,899 for a studio · two ₹3,798 for a 2BHK · three ₹5,697 for a 3BHK · four ₹7,596 for a 4BHK.

Fragrance, monthly: about ₹36 per machine at four drops a tank, one fill a day, buying 300ml at ₹1,799 — roughly ₹6 a millilitre.

The whole 2BHK: ₹3,798 in year one plus ₹864 of fragrance, then ₹72 a month after that.
The short answer
Short answer: A fully scented two-bedroom flat costs about ₹3,798 once — two Sukoons at ₹1,899 each, each shipping with three 15ml fragrances — and about ₹72 a month in fragrance after that. A studio is ₹1,899 and roughly ₹36 a month. A 3BHK is ₹5,697 and roughly ₹108 a month.
Where the money actually goes: Into machines, not bottles. In a three-machine home the hardware is ₹5,697 and the fragrance is about ₹1,296 a year. Over five years the machines still account for the larger share, which is why the decision that costs you money is how many rooms you scent, not which bottle you buy.
The number to work out first: Millilitres a month. At the recommended three to six drops a tank and one fill a day, one machine uses roughly 6ml a month. Multiply by your machine count, multiply by ₹6 for a 300ml bottle, and you have your recurring bill in one line.
Straight answer
What does it cost to scent a whole home in India?
1. Hardware, once, by room count. A Sukoon is ₹1,899 and covers 270–320 sq ft, which is one ordinary Indian room. One for a studio, two for a 2BHK at ₹3,798, three for a 3BHK at ₹5,697, four for a 4BHK at ₹7,596. A Boond at ₹899 does a small bedroom or a study.

2. Fragrance, monthly, and it is small. A 300ml bottle is ₹1,799, which is about ₹6 a millilitre. At four drops a tank — roughly 0.2ml — and one fill a day, a machine gets through about 6ml a month. That is about ₹36 per machine per month.

3. So year one is the expensive year, by a wide margin. A 2BHK costs ₹3,798 of machines plus ₹864 of fragrance in the first twelve months — about ₹389 a month. From month thirteen it drops to about ₹72 a month, because you already own everything except the bottle.

4. The Sukoon arrives with fragrance in the box. Three 15ml Hotel Collection scents of your choice come with each Sukoon. Bought separately those are ₹299 each, so ₹897 of the ₹1,899 is fragrance. Day one costs you nothing more than the machine.

5. The line that saves the most is the room you skip. Every machine you do not buy removes ₹1,899 from year one and ₹36 a month forever. Corridors, guest rooms used twice a year and utility areas are the rooms to leave alone — and leaving them alone is not a compromise, it is the correct answer.

TL;DR: scenting a home is hardware once plus fragrance monthly. Sukoons are ₹1,899 a room; fragrance runs about ₹36 a month per machine on a ₹1,799 300ml bottle. A 2BHK is ₹3,798 and then ₹72 a month. The expensive decision is how many rooms you scent, not which bottle you buy.

The unit of the budget
SOSA Sukoon · 500ml ₹1,899
Every whole-home number on this page is a multiple of this one. ₹1,899 covers 270–320 sq ft — one ordinary room — runs 16–18 hours a fill on low, and ships with three 15ml Hotel Collection scents, so it is a finished setup rather than a deposit on one.

Why a single figure cannot answer this question

The reason nobody gives you a straight price is that two different kinds of spending are hiding inside the question, and they behave in opposite ways. Hardware is capital: large, one-off, and finished the day it arrives. Fragrance is consumption: small, repeating, and open-ended. Quote only the hardware and you look expensive and slightly dishonest. Quote only the fragrance and you look cheap and slightly dishonest. The useful answer is both, kept apart, with a time period attached — which is why every table on this page has a "once" column and a "per month" column rather than one grand total pretending to be an answer.

The second reason is that the hardware number is set by something most people have not decided yet: how many rooms they are actually going to scent. That is not the same as how many rooms they have. A 1,300 sq ft 3BHK contains a living-dining zone, three bedrooms, a kitchen, two bathrooms and a passage — nine spaces if you count doors, and about three worth spending ₹1,899 on. Fragrance does not pass through a closed door, so each closed room is its own separate purchase, and each closed room you decide to leave alone is ₹1,899 saved immediately and ₹36 a month saved for as long as you live there. The budget is therefore decided by a floor plan and a bit of honesty about where you spend your evenings, long before it is decided by a price list.

The three decisions that set your bill

1
DECISION ONE · HOW MANY MACHINES
This is ninety per cent of the number
SOSA Sukoon diffuserSOSA Sukoon₹1,899Count air spaces, not square feet. An open living-dining-kitchen is one space and takes one Sukoon at ₹1,899. Every bedroom whose door is shut is another. So a studio is ₹1,899, a 1BHK is ₹1,899 or ₹3,798 depending on that door, a 2BHK is usually ₹3,798, a 3BHK ₹5,697 and a 4BHK ₹7,596. A Boond at ₹899 is the correct machine for a room under about 150 sq ft — a small second bedroom, a study, a child's room — and swapping one Sukoon for a Boond takes ₹1,000 off the total without costing you anything in that room.
The rule: for more area, buy more Sukoons. Never a Megh — at ₹3,499 it covers 215 sq ft, which is less than a Sukoon.

DECISION TWO · WHICH BOTTLE SIZE
Where the recurring cost is actually decided
The same fragrance costs three different amounts per millilitre depending on the bottle you pick it up in. A 15ml is ₹299, which is about ₹20 a millilitre. A 100ml is ₹999, about ₹10. A 300ml is ₹1,799, about ₹6. Nothing else in this budget varies by a factor of three, so this is the one line where attention pays. The catch is that the cheap-per-millilitre bottle is the expensive-to-be-wrong-about bottle: buying a 300ml of a scent you turn out to dislike costs ₹1,799 and sits in a cupboard. The sensible sequence is to test at 15ml, commit at 300ml, and never buy 15ml bottles as your ongoing supply — that is the most common quiet overspend in home fragrance.
The maths: 15ml ≈ ₹20/ml · 100ml ≈ ₹10/ml · 300ml ≈ ₹6/ml. Same liquid, three prices.

DECISION THREE · WHAT YOU LEAVE UNSCENTED
The cheapest line in any budget
Corridors, stairwells and passages take fragrance from the rooms on either side of them and give nothing back — a machine there is ₹1,899 spent on a space nobody stands still in. Bathrooms are usually better served by something with no tank to fill. Guest rooms used twice a year should be scented twice a year, by moving a machine, not by buying one. Kitchens are a losing fight while anything is on the hob. Strike those four categories off a typical 3BHK and the machine count falls from a nervous six to a comfortable three, which is ₹5,697 rather than ₹11,394 — and the three-machine version smells better, because the fragrance is concentrated where people actually are.

What each home type actually costs

Hardware first, since it is the number that decides the rest. Machine counts assume the bedroom doors are shut for at least part of the day, which is what makes each bedroom a separate purchase. Areas are rough and vary hugely by city.

Hardware by home type
The one-off number, by how many rooms you are prepared to scent
Home Roughly Rooms worth scenting Hardware, once
Studio / 1RK 300–450 sq ft One — the whole flat is one air space ₹1,899 (1 Sukoon)
1BHK 450–650 sq ft One or two, depending on whether the bedroom door shuts ₹1,899 – ₹3,798
2BHK ★ 700–1,100 sq ft Living-dining, master bedroom — the second bedroom is optional ₹3,798 (2 Sukoons)
3BHK 1,200–1,600 sq ft Living-dining and two bedrooms in daily use ₹5,697 (3 Sukoons)
4BHK 1,800–2,500 sq ft Living-dining and three bedrooms ₹7,596 (4 Sukoons)
Duplex / villa 1,500–3,000+ sq ft Bedrooms as above, plus one large connected common volume Sukoons + Vaayu ₹11,999
Two ways to take money out of this table: swap a Sukoon for a Boond at ₹899 in any room under about 150 sq ft, and buy the machines one at a time rather than all at once — a staged purchase costs exactly the same and stops you buying for a room you turn out not to use.

What the money buys — machines once, fragrance monthly
The SOSA principle
The bill people brace for is the refills. The bill that actually lands is the machines — and it lands once.
At ₹6 a millilitre and 6ml a month, a machine costs about ₹36 a month to run. The room you decided to scent costs ₹1,899.

Working out your own monthly figure in three lines

Start with millilitres, not rupees. A drop from a dropper bottle is roughly a twentieth of a millilitre — twenty drops to the millilitre is the usual figure — so the recommended three to six drops a tank is somewhere between 0.15ml and 0.3ml. Call it 0.2ml a fill at four drops, which is where most people settle once the novelty wears off. One fill a day is 6ml a month. Two fills a day at six drops is 18ml a month. Those two figures bracket almost every household in India, and everything else follows from them.

Then convert. The Hotel Collection costs about ₹6 a millilitre in a 300ml bottle at ₹1,799, about ₹10 in a 100ml at ₹999, and about ₹20 in a 15ml at ₹299. So one machine run modestly is about ₹36 a month on a 300ml, ₹60 on a 100ml, ₹120 on 15ml bottles. Run hard — two fills a day, six drops — it is about ₹108 a month on a 300ml. Multiply by your machine count and you have the whole recurring bill: three machines run modestly is about ₹108 a month, three machines run hard is about ₹324.

Then check it against how long a bottle lasts, because that is the sanity test people actually feel. At 6ml a month, a 300ml bottle is the better part of four years for one machine, or about seventeen months across three. A 100ml at ₹999 is roughly sixteen months on one machine. A 15ml is around two and a half — which is exactly right for testing a scent and exactly wrong as a standing order. In practice you will change fragrance before you finish a 300ml, and that is fine; it means the constraint on this hobby is your taste, not your budget.

Nobody is bankrupted by refills. People are surprised by the fourth machine — and the fourth machine is always optional.

Honest notes before you buy: the arithmetic assumes four drops a tank, one fill a day, and 300ml bottles at ₹1,799 — around ₹6 a millilitre. Buy 100ml at ₹999 instead and the monthly figures rise by roughly two-thirds; buy 15ml at ₹299 as your ongoing supply and they roughly triple. Each Sukoon ships with three 15ml scents, so year one's fragrance line does not actually start until those run out. These are ultrasonic, water-based fragrances — they add a little humidity, welcome in a dry or air-conditioned flat and less so in a coastal monsoon. They are not for reed diffusers or for the waterless Vaayu (₹11,999) and Aangan (₹25,999), which run neat oil and cannot take water-based fragrance. The machines are imported from China; the Hotel Collection fragrances are composed and made in India. Use filtered water in hard-water cities, rinse between scents, keep fragrance away from children and pets. SOSA is independent and not affiliated with any hotel brand.

A note from Sonal

People arrive at this question braced for a subscription. They have been trained by printer cartridges and coffee pods to assume the machine is bait and the refills are the trap. That is not the shape of this category. The machines are the expensive part, they are bought once, and the fragrance costs less per month than a single cup of filter coffee in a Pune café.

What I would rather people worried about is machine count. Every extra machine is ₹1,899 that does not come back and a small permanent addition to the monthly line, and the fourth or fifth one is almost always bought for a room nobody sits in. I have talked more customers out of a machine than into one, and the flats that end up smelling best are consistently the ones with fewer, better-placed units.

So work it out in this order: which rooms, then how many machines, then one good bottle to share between them. Three drops, one fill a day, and a 300ml that will outlast your interest in the scent. A portion of every order funds a girl's classroom through Nanhi Kali, which is the one line in the budget I would not cut.

Frequently asked questions

What does it cost to scent a whole home?
Two numbers. Hardware once: a Sukoon is ₹1,899 per room, so ₹1,899 for a studio, ₹3,798 for a 2BHK, ₹5,697 for a 3BHK and ₹7,596 for a 4BHK. Fragrance monthly: about ₹36 per machine at four drops a tank and one fill a day, buying 300ml bottles at ₹1,799. A 2BHK is therefore ₹3,798 up front and about ₹72 a month thereafter.
How much do diffuser refills cost per month in India?
Around ₹36 a month per machine if you buy a 300ml Hotel Collection bottle at ₹1,799, which works out at roughly ₹6 a millilitre. At four drops a tank — about 0.2ml — and one fill a day, a machine uses roughly 6ml a month. Run two fills a day at six drops and it is closer to ₹108. Buying 15ml bottles at ₹299 as your ongoing supply roughly triples the figure.
Is the fragrance or the machine the bigger expense?
The machine, comfortably, and for several years. Three Sukoons are ₹5,697 against roughly ₹1,296 a year of fragrance at ordinary use. Even at five years the hardware is still the larger share for most households. This is why the decision that actually moves your budget is how many rooms you scent, not which bottle size you pick up.
Do I need to buy fragrance separately when I buy a Sukoon?
Not on day one. Each Sukoon ships with three 15ml Hotel Collection scents of your choice, so ₹1,899 is a complete working setup. Bought individually those three bottles would be ₹897. You will want a larger bottle eventually, and when you do, the 300ml at ₹1,799 is the sensible one — it is about a third the price per millilitre of a 15ml.
What is the cheapest way to scent a whole flat?
Fewer machines, placed properly, sharing one large bottle. A Boond at ₹899 handles any room under about 150 sq ft, so a 1BHK can be done for ₹2,798 rather than ₹3,798. Leave corridors, kitchens and rarely-used rooms unscented — each one skipped saves ₹1,899 and about ₹36 a month. Then buy a single 300ml bottle rather than one small bottle per machine.
