8 x 4 m oval pool

pool plan

Family pool

A full family pool: a shallow end where kids stand and games happen, a proper deep end for diving-free swimming, and enough length that two people can swim without negotiating. This is the most-built size class in private gardens for a reason.

The oval trades corners for one continuous curve. It sits beautifully in planted, informal gardens and among period houses, and the long axis still gives a proper swimming line. Circulation is excellent because there are no corners at all for water to stall in.

What it costs to build

A rough installed-cost range per construction type, at this size — the pool itself, with basic coping. Not a quote.

ConstructionInstalled costNote
Liner or membrane€26,000–€44,000Over a block or concrete shell; the least expensive route to any shape.
Tiled concrete€39,000–€64,000A poured shell finished in tile; built to any shape, the most durable finish.
One-piece fiberglass€23,000–€39,000Fastest to install; limited to sizes and shapes a mould exists for.

Rough 2026 estimates for the pool installed with basic coping — excavation, shell and basic equipment. Excludes deck, fencing, landscaping, heating and permits, all of which vary by site and by builder; get real bids before budgeting from these figures.

Questions about this plan

How much water does the 8 × 4 m pool hold?
About 9,050 gal (37.8 tons of water) at 3′ 11″–5′ 11″ depth — computed from the actual pool outline, not a rule of thumb.
How long does it take to fill?
Roughly 23 hours from a standard garden tap (~6.6 GPM). A water delivery service fills it in a few hours.
Is this size right for my garden?
The water surface is 270 sq ft; plan roughly 1.5–2× that footprint including the surrounding deck. Open the plan in the designer and set your own deck margins to see the full footprint.
Can I change the depth or edge type?
Yes — open the plan in the designer and adjust depths, edge system (skimmer, deck-level overflow or raised), finishes and accessories freely.
How much does the 8 × 4 m oval pool cost to build?
Roughly €23,000 to €64,000 installed at this size, depending on construction type — before deck, fence, landscaping, heating or permits. See the cost table above for the range per type.
