Sand is the cheapest play material in the garden and the one parents worry about most. The worries are manageable with three habits and one honest rule about cats. Here is the complete practical guide.
Which sand is actually play sand
Buy sand sold explicitly as play sand: washed, screened and rounded. Builder's sand is the tempting mistake — cheaper, but sharper-grained, dustier, and often stains skin and clothes. The difference costs a few euros a bag and is worth every one of them. For a sandpit under a swing set fort, 15–20 cm of depth is plenty — enough to dig, not enough to excavate to the subsoil.
The three habits that keep it clean
- Cover it when unused. An uncovered sandpit is, to every cat in the neighbourhood, a serviced amenity. A simple fitted cover or tarpaulin ends the problem entirely — this is the single non-negotiable habit.
- Rake it weekly in season. A quick rake surfaces leaves, toys and anything that should not be there, and keeps the sand aerated so rain drains rather than souring it.
- Let it dry. After heavy rain, fold the cover back and let sun and air do the hygiene work. Permanently damp sand in shade is where problems start; a sandpit under an open fort deck — as on our compact sets — gets shade in play hours and airflow the rest of the day, which is the right balance.
When to change it
With the cover habit, once a year at spring recommissioning is the honest schedule — more often only if it has taken contamination you know about. Change it immediately, not on schedule, if it smells sour, stays wet through dry weather, or the cover habit failed for a month of holidays. Sand is cheap; doubt is not worth keeping.
Sand and the swing set
The space beneath a fort is the best sandpit site in the garden: shaded, contained on posts, and inside the area you already supervise. The Sunnydale leaves exactly this room under its fort deliberately. Edge it with timber, fill with play sand, and the set gains a ground floor for the youngest child while older ones climb above — the full logic is in our accessories and extensions guide.
