What Is a Sun Shelf (Tanning Ledge) and Should Your Pool Have One?

Almost every homeowner we consult with asks about sun shelves — sometimes called tanning ledges, Baja shelves, or wet decks. They’ve become one of the most popular pool features we build, and for good reason. But they’re not right for every pool or every homeowner, and the design details matter.

Here’s everything you need to know.

What a Sun Shelf Is

A sun shelf is a large, shallow platform built into the pool, typically at one end. Water depth over the shelf is usually between 6 and 18 inches — deep enough to sit in a lounge chair with water around your ankles and calves, shallow enough for young children to play safely under close supervision.

The shelf is built as part of the pool structure — it’s not an add-on or accessory but an integrated design element formed into the gunite shell. It’s typically separated from the main pool by a subtle ledge or step.

Sun shelves are also where pool-safe lounge chairs (designed to sit partially submerged) get used. The “in-pool chair” look that’s popular in resort pools is what most homeowners are envisioning when they ask about a sun shelf.

Common Design Variations

Simple ledge. A flat, broad shelf at one end of the pool with a defined step edge into the main pool. The most common configuration.

In-line shelf with umbrella sleeve. Includes a pre-installed sleeve in the shelf for a cantilever umbrella — allows you to shade the shelf area. A minor detail during construction, a significant quality-of-life improvement in Bakersfield summers.

Bubblers or deck jets over the shelf. Bubblers are small fountains that project from the shelf floor — kids love them, and they add a resort feel. The water sound also helps mask noise from neighbors or nearby streets. Deck jets can be aimed to arc over the shelf from the pool coping, creating a water feature effect.

Integrated spa positioning. Some designs place the spa adjacent to the sun shelf rather than at the opposite end of the pool, creating a configuration where the spa spills into the shelf area. This works particularly well for homeowners who want a relaxation zone rather than an active swimming zone as their primary pool use.

Practical Considerations

Orientation to the sun. A sun shelf is only useful if the sun actually reaches it. We evaluate sun path during every site walk — a shelf that’s shaded by the house during the afternoon hours you’re most likely to use it is a shelf you won’t use.

Size. Sun shelves vary from relatively narrow ledges (5–6 feet deep) to expansive platforms that can accommodate multiple loungers. The size needs to be proportional to the overall pool size and the yard — a massive shelf on a modest pool looks off and eats into swimming area.

Access. The shelf should be reachable by stairs, not just by stepping over a ledge from the deck. We typically design a set of entry steps that transition from the deck through the shelf into the main pool, so the whole entry sequence feels intentional.

Depth consistency. The shelf depth needs to stay consistent across its area. An uneven shelf is uncomfortable to stand on and looks sloppy. Gunite allows for very precise shelf depth control during construction.

Child safety. A sun shelf’s shallow water is safer for young children than the main pool, but shallow does not mean risk-free. Supervision is still required, and the shelf should be designed with the step transition to the main pool clearly defined.

Is It Right for Your Pool?

Sun shelves add cost to a pool build — they’re additional square footage, additional concrete, and typically include additional features like bubblers or umbrella sleeves. In most cases, the cost is well justified by how much the shelf gets used.

The homeowners who get the most value from sun shelves:

• Families with young children who want a safe play area
• Adults who want to “be in the pool” without actively swimming
• Homeowners who entertain and want a social space where guests can sit in the water
• Anyone building in Bakersfield, where soaking in shallow water during peak heat is genuinely refreshing

The shelf is less compelling for homeowners who primarily want a lap pool, who have very small lots where every square foot of surface matters, or who are building a highly formal, geometric design where the shelf would look out of place.

We discuss sun shelf placement, size, and features in every design consultation. It’s one of the decisions that has the most impact on how the pool gets used day-to-day.
