THE SMALL-WATER ARGUMENT, SHORT VERSION: a plunge is not a shrunken pool — it is the densest hydraulics problem in the yard, turning its whole body over in 45 minutes while a big pool takes the morning. Size the plant to the gallons or the chemistry runs the show.

Plunges & plans, from
Prices from last season’s Quarter and Hill builds; the fixed number comes out of the tape-measure visit, which is free. Small water gets the full-size treatment: salt, automation, hydraulic math and a published fill date, all sized to gallons the big crews would not stop for.

How Petalight runs
The nine-day yard
Compact shells, one crew, and a sequence measured in working days: tape-measure visit, crane study, set, plumb, finish, float. The plant pack is the heart of it — pump, filter, salt cell and controller sized to real gallons, mounted tidy enough for a courtyard the neighbours can see straight into. Small lot, full engineering, and no compromise hiding in the footprint.
A plunge turns its whole body over before a big pool finishes its coffee — at this size, hydraulics is the entire product.
How it goes
Cone to first float
The same sequence on every job — the only variable is your project.
Day 1
The tape-measure visit
Every corner of access measured, the crane study sketched, the neighbours’ fences noted. Compact lots are won at the tape: what comes over the roof, what squeezes through the alley, what fits where the big crews stopped looking.
Days 2–3
Permits & the crane study
Street-use permit, rigging plan, utility marks — and the shell on order to the half-inch. If the set cannot be done safely, day one already told us; nothing gets discovered on crane day.
Days 4–6
Set, plumb & the pack
The shell flies in over the garage or slips through the alley, the plant pack lands beside it, and the plumbing runs are short, straight and labelled — a luxury big pools never get.
Days 7–9
Finish, fill & float
Coping set, salt cell commissioned, automation paired to your phone, the fill balanced and the log live. First float scheduled for the ninth day, at a quarter past warm.
2025 — 2026, the Quarter & the Hill
Small water, photographed
Six plunges from last season, shot from the corners their owners actually sit in. Every one went up on a lot at least two big crews declined — the captions name the access that made it possible, because on this street the access IS the story.
Fair questions
Questions from small yards
The five the Quarter asks on every stoop once the crane leaves somebody’s street. The shop line answers seven to five, Marigold time, and the crane study answers the rest on paper.
How small is too small?
Almost nothing is too small — it becomes a question of what the water is for. A courtyard of four metres square takes a beautiful plunge; a side yard two metres wide takes a spa; and the stitch-district laplet exists because a row house with nine feet of width still deserves real lanes. If two people can stand in it shoulder to shoulder, we can build water in it.
Can a crane really get a pool over my house?
Usually, and the study is the whole answer: load paths over the roof structure, reach charts against your actual street, and the set rehearsed on paper before anyone books a rig. Eleven shells went over garages last season at weights from nine to fourteen tonnes. When the study says no, it says so on day one — and the alley plan takes over.
Do plunges work in winter?
The insulation and the lid do the quiet work, and the pack does the rest: a freeze-protection cycle that runs when the temperature does, an optional heat loop that turns the plunge temperate for the shoulder months, and a log that watches all of it through February. Half our Quarter clients run cold all year on purpose; the other half switch modes and never drain.
Is a plunge also a spa?
It can be — that is the spool, and it is a genuinely different animal from either parent: a compact shell on a hybrid plant that holds 46 for the morning ritual and 104 for the evening one, changing over on a schedule. The Rooftop Spool in the price card is exactly that, and the pair option keeps the two temperatures in two bodies instead.
What about the neighbours?
Compact water is polite by design: the plant pack runs quieter than the air conditioner it usually sits beside, the schedule keeps the pump’s real work in the small hours on cheap power, and the salt system ends the chlorine-breeze era for good. Eleven rooftop sets last season ended with more neighbours asking for the number than complaining about the crane.
Three companies told us the courtyard was impossible without actually measuring it. Petalight brought a tape, a crane study and a plan for the five-foot gate — and nine working days after the first cone, the whole street was around a plunge we were told could not happen. The plant pack sits by the herb bed and you cannot hear it from the kitchen.
The crane came at seven and the pool was wet by lunch — rehearsed on paper until it was boring, exactly as promised. The spool holds 46 for my mornings and 104 for my wife’s evenings, the changeover runs itself, and the log has never once wandered out of spec. Our garage roof now has a better tenant than the car did.
The laplet is the row house’s only luxury and it is a real one: two lanes, honest depth, the water turning over twice before breakfast. Our twins train before school in a yard the big crews photographed and then declined. Nine days, one crew, and a plant pack the neighbours have stopped noticing entirely.

The address, the alley, the gate widths — the details that made the big crews polite. The tape-measure visit is free, the crane study happens on day one, and nine working days later the water is warm and the courtyard is a different place. plunge@petalight.example
