Ø 18 ft Round
pool plan
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.
A round pool is the most social shape there is: everyone faces everyone, there's no deep-end hierarchy, and it drops into a small garden or courtyard without dominating it. It's the natural choice for cooling off, kids' play and spa-like plunge pools rather than lap swimming.

Questions about this plan
- How much water does a Ø 18 ft pool hold?
- About 9,385 gal (39.2 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 24 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 254 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.
