Week 0Decide what the pool is for
Before a spade touches the lawn, one decision sets every other: what the pool is for. Cooling off, real swimming, or a heated soak twelve months a year? Ours is a family pool — an 8 × 4 m rounded rectangle with room to swim and a shallow end to stand in — and its outline is sprayed on the grass.
Woorden die je deze week hoort
- Plunge poolA small, usually uniformly deep pool (up to ~13 m²) built for immersion rather than swimming — cooling off, soaking, cold plunges.Lees de volledige uitleg →
- Lap poolA long, narrow pool built for exercise swimming — typically 12–25 m long, 2.5–4 m wide, uniformly ~1.35 m deep.Lees de volledige uitleg →
- Swim spaA compact heated basin (4–6 m) with a powerful counter-current for swimming in place, often doubling as a hot tub.Lees de volledige uitleg →
Week 1Set out and dig
The digger arrives and the lawn becomes a hole with a slope in it — deeper at one end than the other. That slope is the first design decision you can see: 1.2 m where children will stand, 1.8 m where adults will swim. If the ground is wet, a valve in the floor stops groundwater from floating the finished pool.
Woorden die je deze week hoort
- ExcavationDigging the hole the pool sits in — the shell's shape plus working room around it, and the slope from the shallow end down to the deep end already in the ground.Lees de volledige uitleg →
- Shallow endThe standing-depth zone of the pool, typically 1.0–1.2 m — where children play, adults wade and steps arrive.Lees de volledige uitleg →
- Deep endThe deepest zone of the pool, typically 1.8–2.0 m in family pools — deep enough for free swimming and treading water.Lees de volledige uitleg →
- Hydrostatic valveA one-way valve in the pool floor that lets groundwater into the empty basin instead of letting it lift the shell out of the ground.Lees de volledige uitleg →
Week 2–3The shell
Steel goes in, concrete is sprayed over it, and the hole becomes a basin. Everything built into the pool is formed now, while the walls are bare: the steps, the tanning ledge, the drain at the deep point and the inlets that will push clean water back. What you decide this week is cast in concrete — literally.
Woorden die je deze week hoort
- Pool shellThe structural basin of the pool — reinforced concrete, sprayed gunite, factory fiberglass or panel construction — that carries water and ground pressure.Lees de volledige uitleg →

- Fiberglass poolA one-piece factory-molded basin craned into a prepared excavation — the fastest route from order to swimming.Lees de volledige uitleg →
- Pool linerA waterproof PVC membrane fitted over the pool structure — the budget-friendly waterproofing and finish in one layer.Lees de volledige uitleg →
- Main drainA suction point at the pool's deepest point that pulls water from the bottom into the filter circuit and makes full draining possible.Lees de volledige uitleg →
- Anti-vortex coverA domed or channeled drain cover that breaks suction vortices, preventing hair or limbs from being trapped at the main drain.Lees de volledige uitleg →

- Tanning ledgeA large flat shelf 10–40 cm below the surface — usually 15 cm — sized for in-water loungers, toddlers and lounging.Lees de volledige uitleg →
- Roman stepsSemicircular steps flowing out of the pool wall in concentric arcs — the classical entry borrowed from Roman baths.Lees de volledige uitleg →
- Beach entryA gently sloping, zero-depth entry that starts at deck level and descends like a natural shore — no steps at all.Lees de volledige uitleg →
Week 4The edge
How the pool meets the deck is the most architectural choice of the build. Ours is a skimmer pool: a ring of travertine coping caps the wall, the water will sit a hand's width below it, and two wall skimmers will sip the surface clean. A deck-level pool would instead spill over its rim into a hidden channel.
Woorden die je deze week hoort
- CopingThe ring of finished stone or masonry that caps the pool wall at the waterline — the edge your hand grabs and your eye reads as the pool's outline.Lees de volledige uitleg →
- FreeboardThe vertical distance between the water surface and the top of the pool edge — typically ~15 cm in skimmer pools, near zero in deck-level overflow pools.Lees de volledige uitleg →
- SkimmerA wall-mounted unit that draws the top few centimetres of pool water into the filtration circuit, harvesting floating debris, dust and oils before they sink.Lees de volledige uitleg →
- Deck-level overflowAn edge system where the water stands flush with the surrounding deck and continuously spills into a hidden perimeter channel, from which it is filtered and returned.Lees de volledige uitleg →
- Infinity edgeA vanishing-edge wall lowered to a precise weir so water sheets over it into a catch basin below, visually merging the pool surface with the landscape behind.Lees de volledige uitleg →
- Overflow gutterThe perimeter channel of a deck-level pool that catches the continuously overflowing water — finished as a grate or a narrow slot.Lees de volledige uitleg →
- Balance tankA buffer reservoir that overflow and infinity pools need: it receives the water spilling over the edge and feeds the pump, absorbing the level swings caused by swimmers.Lees de volledige uitleg →
Week 5The surfaces
Now the basin gets its skin, and the colour of the water gets decided — not by the water, which is nearly clear, but by the finish under it. Ours is white plaster, which reads as bright turquoise once it is wet, with a band of porcelain tile at the waterline where scale and sunscreen collect.
Woorden die je deze week hoort
- Pool plasterA seamless cementitious interior finish (marcite, quartz or polished aggregate) troweled over the shell.Lees de volledige uitleg →
- Porcelain pool tileFully vitrified ceramic tile with near-zero water absorption — frost-proof, colorfast and chemically inert, the most durable pool interior.Lees de volledige uitleg →
- Mosaic tileSmall-format tile (2–5 cm) mounted on mesh sheets — the format that wraps curves, radii and Roman steps without cutting.Lees de volledige uitleg →
- Pool groutThe joint filler between pool tiles — in pools always a water-resistant epoxy or high-grade cementitious grout that survives permanent immersion and chemicals.Lees de volledige uitleg →
- Waterline tileThe band of tile at the water's surface where scale, sunscreen and grime concentrate — tiled even in otherwise plastered pools because tile scrubs clean.Lees de volledige uitleg →
Week 6The deck
The pool is only half the picture; the deck is the room it lives in. Pavers go down around the coping, the lounging side gets its two metres, everything drains away from the water, and at one end a pit is formed where the cover's roller will hide.
Woorden die je deze week hoort
- Pool deckThe paved area surrounding the pool — the room the pool lives in. Slip resistance, barefoot-friendly surface temperature and drainage away from the pool are its three duties.Lees de volledige uitleg →
- PaverA modular deck element — porcelain, concrete or natural stone — laid on a bed or pedestals around the pool.Lees de volledige uitleg →
- TravertineA porous natural limestone in warm cream-to-walnut tones — the classic Mediterranean coping and deck stone.Lees de volledige uitleg →
- Cover pitA recess at one end of the pool — under a bench, behind a wall or below the deck — housing the roller of an automatic slatted cover.Lees de volledige uitleg →
Week 7Water in
Thirty-two hours of garden tap, and the plant room wakes up: pump, filter, heater. From now on the water lives in a loop — out through the skimmers and drain, through the filter, back through the inlets — and keeping it clear is a five-minute weekly ritual, not a chore.
Woorden die je deze week hoort
- Turnover rateThe time the circulation system needs to pass the pool's entire volume through the filter once — typically 4–6 hours for private pools.Lees de volledige uitleg →
- Sand filterThe classic pool filter: water passes through a bed of sand (or glass media) that traps particles, cleaned by backwashing.Lees de volledige uitleg →
- Cartridge filterA filter using pleated cartridges instead of sand: finer filtration, no backwash water waste, but cartridges need periodic rinsing and replacement.Lees de volledige uitleg →
- ChlorineThe standard pool sanitizer: it oxidizes organic matter and keeps bacteria and algae from growing.Lees de volledige uitleg →
- pHThe acidity measure of pool water; the target band is 7.2–7.4, where sanitizers work best and eyes and skin stay comfortable.Lees de volledige uitleg →

Week 8Fit-out
The fittings people actually touch. Warm lights in the wall so the pool is still there at nine in the evening, a ladder at the deep end so swimmers get out without crossing the shallow zone, and — if length is short — a current to swim against.
Woorden die je deze week hoort
- Pool lightsSealed LED fixtures set into the pool wall about 50 cm below the waterline, wired through conduits cast into the shell.Lees de volledige uitleg →
- Pool ladderA stainless-steel entry that takes no swim space: two rails over the coping and rungs down into the water, usually at the deep end.Lees de volledige uitleg →
- Counter-current unitA powerful jet that produces an adjustable current to swim against — endless swimming in place, even in a 5-metre pool.Lees de volledige uitleg →
Week 9Cover and care
The last delivery is the one that pays for itself: a cover that goes on every night and halves the heating bill. Then the robot takes over the floor, and the pool asks for twenty minutes a week — until autumn, when it gets tucked in for winter.
Woorden die je deze week hoort
- Solar coverA floating bubble-foil blanket that warms the water a few degrees and, more importantly, stops evaporation — the pool's biggest heat loss.Lees de volledige uitleg →
