Tanning ledges: the shallow shelf everyone uses
Ask pool owners about their favorite square metres and the tanning ledge wins: 15 cm of water where all the lounging happens.

What it is and why it works
A tanning ledge (sun shelf, Baja shelf) is a large flat platform 10–40 cm below the water surface — usually at 15 cm. It's shallow enough for loungers, toddlers and drinks, and wet enough to keep you cool while you sunbathe. It bridges the gap between deck life and pool life, which is why everyone gravitates to it.
Sizing it right
For actual lounging, plan at least 2 m of reach into the pool — a lounger is 2 m long — and 2.5–3 m of width for two loungers side by side. A full-width ledge across one end looks the most architectural; in our designer a ledge set to the pool's width automatically meets both side walls.
Keep it to a reasonable share of the pool: on a 8 × 4 m pool a 3 × 1.5 m ledge leaves the swim area intact; on a 6 × 3 m pool the same ledge takes a third of the water.
Depth: 15 cm is the sweet spot
At 10 cm the ledge dries loungers' feet but waves splash over; at 15 cm loungers sit stable and water cools you properly; at 25–40 cm it becomes a kids' pool and a bench-depth zone. If you'll use in-water loungers, check their base height — most want 12–20 cm of water.
Frequently asked questions
- Does a tanning ledge count as swimming area?
- No — treat it as furniture space. Size the swimming part of the pool as if the ledge weren't there.
- Can I add umbrellas?
- Yes — plan a sleeve anchor in the ledge floor during the build. Afternoon shade turns the ledge into an all-day zone.
- Ledge or wide steps?
- Steps get you in; a ledge keeps you there. If you have length to spare, do both: steps beside a ledge is the most-used layout we see.
