15 × 30 ft Rectangular
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.
The rectangle is the default for a reason: it gives you the most swimmable water for a given footprint, plays well with modern architecture and lap swimming, and makes covers, solar blankets and automatic cleaners simple. Straight walls also keep formwork and tiling straightforward, which builders appreciate.

Questions about this plan
- How much water does a 15 × 30 ft pool hold?
- About 16,553 gal (69.1 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 42 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 450 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.
