Strong enough to be called clean. Never strong enough to be described

Nobody can give you a number for this, and any supplier who does is describing their assumptions rather than your building. The setting that produces the right result depends on the volume of your reception, how much air is moving through it, how often the door opens, what the climate is doing that month, and what else is contributing smell nearby. Two day spas of identical floor area can need noticeably different settings. What can be given is a test, and it is quick, free and reliable. Send somebody who has not been inside the building to walk in from the street at your busiest hour, and ask them one question: what did you notice in the first three or four seconds? There are three useful answers. If they say the place smells clean, or pleasant, or that nothing in particular stood out in a positive way, the setting is right and you should change nothing. If they can describe the fragrance - name what it reminds them of, identify a material, or comment on it as a feature of the space - it is too high, however much you like the register, because in a premium room being noticeable is the failure state rather than the success state. And if they notice something that is not your fragrance at all - damp, laundry, a drain, chlorine from a wet area, cooking from a pantry - then you do not have a fragrance problem. You have a source problem, and adding more fragrance will make it worse, because fragrance combines with an existing smell rather than masking it and the combination is reliably worse than either alone. Three conditions make the test valid. It has to be somebody from outside, because everybody who works in the building adapts to a steady background within about an hour of arriving and stops perceiving it entirely - which is why your team will sincerely and honestly report that the fragrance has stopped working when it is running exactly as specified, and why acting on those reports pushes a spa upward over months until arriving guests meet something considerably stronger than anybody intended. It has to be at the busiest hour rather than at opening, because a spa is warmer, damper and fuller in the afternoon than it is at nine in the morning, and every register reads heavier in those conditions - the busy state is the state the setting has to be right for. And it has to be repeated, weekly rather than once, because the correct setting moves with the season: humid air carries fragrance more slowly and clears it less readily, so a level judged well in a dry month reads considerably heavier in a wet one with nothing changed but the weather. Two things are specific to a day spa entrance and affect the setting directly. The first is that your door is an exchange point. A day spa typically opens onto a street, a building lobby or a mall corridor, and every opening swaps your conditioned air for whatever is outside. In a busy period that happens constantly, so the room is being flushed continuously - and the intuitive response is to raise the setting, which is wrong. High replacement argues for continuous supply rather than higher intensity: something running continuously keeps replacing what the door removes, while something delivered in strong intermittent bursts is partly gone before it has done anything and produces a swing between too much and nothing. It also means the corridor or street outside is arriving in your reception all day, which no internal register excludes - what can be managed is the threshold, the internal circulation, and your own sources. The second is that the entrance should sit at the working level of the building and never above it. The temptation is to make the door the strongest point, on the reasoning that the door is where the impression is made. It is where the impression is made, and that is exactly why it should not be strong: the entrance holds the only unadapted nose that will ever be in your building, and a generously set register met at the sharpest moment of perception reads as applied rather than as inherent. Accuracy, not strength. From there, the level descends inwards - corridors need little of their own, being conduits, and treatment rooms take the lowest level anywhere, because a guest lies in one for an hour or more and a therapist is in it all day. On register at an entrance, Warm Welcome, with citrus, floral and sandalwood, is the most overtly welcoming we make and is well placed at a door. Quiet Luxury, with white tea, bergamot and cedar, is the safest and works at the entrance and throughout, which is an advantage since the register should not change as a guest moves inwards. Tea Garden, with jasmine, green tea and white tea, is a soft green-floral doing a similar job. Forest Suite, with cedarwood, vetiver and green leaves, is right for a spa built from stone and warm wood. Old-World Glamour, with amber, violet and woods, suits a dark warm-toned reception at a low level. White Tea Serenity, with white tea, aloe and cedar, is the softest we make and belongs deeper in the building rather than at a door. Lobby Bar, with citrus, pepper and amber, is characterful and belongs in circulation. On running and hardware, run continuously at the chosen level rather than in bursts, and run before you open - a spa whose system starts at opening spends its first hour mixing, and the first guests meet an undistributed room, which matters here more than anywhere since the entrance is where the assessment happens. Reception is its own zone, because a machine distributes through connected moving air and cannot cross a closed door. The Sukoon at Rs 1,799 suits a compact reception; the Megh at Rs 3,499 with its 6L tank a substantial one; and the Vaayu at Rs 11,999 a large open reception or lounge, waterless with no tank at all, coverage up to 1,000 square metres or roughly 10,700 square feet, with Bluetooth app and timer control - which in a twelve-hour day spa is what actually holds a setting steady rather than letting it drift upward. The Boond at Rs 799 suits a treatment room, and reeds at Rs 749 to Rs 849 suit rooms behind doors, three to four months from a bottle, refills at Rs 2,399 for 300ml and Rs 3,499 for 500ml. Machines take the water-based Hotel Collection at three to six drops per tank with a rinse between scents, never reed oil, which can damage them. Placement at reception: put the unit in moving air but not on or beside the desk, where the socket usually is - that puts the strongest air in the building next to a receptionist who sits there all day and adapted in their first hour, and next to every guest checking in. And fix the sources before setting anything: wet towels, laundry, drains and wet-zone air are ventilation, extraction and laundry problems, and the pantry is never scented at any time since cooking smell is aerosolised oil and extraction is the answer. Steam rooms, saunas and shower interiors are not scented. We make no therapeutic, medical or wellness claims of any kind, and SOSA ambient fragrance is for the air of a room only - never for skin, massage oil or any treatment product. Staff should have a physical off switch and never have to justify using it. The seven registers are Rs 299 for 15ml, Rs 999 for 100ml and Rs 1,799 for 300ml, and they are SOSA's own interpretations - we are independent and not affiliated with, endorsed by or associated with any hotel brand. Everything is alcohol-free and made to IFRA-compliant standards, and a portion of every order supports girl-child education through Nanhi Kali. Volume pricing is quoted against the specification on WhatsApp.
