Particular pools and situations
Looking after a plunge pool
A plunge pool holds far less water than a family pool. Every dose, every swimmer and every hot day has a bigger effect.
Plunge pools are common on townhouse terraces, courtyards and rooftop decks. Their small volume makes them quick to heat and cool, but it also means chemistry changes quickly. A dose sized for a larger pool can push pH or chlorine far out of range, and one busy afternoon can use up most of the chlorine.
These guides adapt pool care to a particular season, household or type of pool.
Good care is about precision: knowing the exact volume, measuring doses carefully, testing more often, and making sure the filtration and any heater or chiller are suited to the small volume. Sun exposure on terraces can make the water very warm in summer.
The short version
Small volume, big swings
Chemistry reacts quickly to doses and use.
Measure doses precisely
Calculate from the actual volume.
Test often
Changes happen faster than in larger pools.
Plunge pool care
Volume calculation
Accurate measurements so doses are correct.
Temperature control
Heaters or chillers matched to the small volume, with shading where possible.
Filtration
Run times set to turn the small volume over properly.
Bather load in a small pool
Two or three people in a plunge pool add as much load relative to the volume as a crowd in a large pool, so chlorine drops quickly after use.
Watch for
Rapid chlorine loss
Especially on hot days.
pH swings
After small doses.
Very warm water
In summer on terraces.
Common questions
Can I use the same products as a large pool?
Yes, but in much smaller, carefully measured amounts.
Does a plunge pool need a cover?
A cover helps control temperature and debris.
Is a salt system suitable?
It can be, with output set for the small volume.
How often should a plunge pool be tested?
More often than a large pool — after heavy use and on hot days, as well as at each maintenance visit.
