Ø 12 ft Round
pool plan
A compact family size: big enough for proper swimming strokes and games, small enough that heating, covering and chemistry stay cheap. In most gardens this class hits the sweet spot between water you use daily and garden you keep.
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 12 ft pool hold?
- About 3,737 gal (15.6 tons of water) at 3′ 11″–5′ 3″ depth — computed from the actual pool outline, not a rule of thumb.
- How long does it take to fill?
- Roughly 9 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 113 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.
