The Bench Inside Your Pool: What a Swim-Out Is, Why It’s the Most Overlooked Custom Feature, and How to Design One Right

Your pool contractor probably mentioned a tanning ledge — but the feature most homeowners wish they’d added is the one that goes deeper.

A swim-out bench is a submerged ledge, typically 18 to 24 inches wide, built directly into the wall of your pool. It sits at a depth of 18 to 36 inches, putting water at your waist or chest when you’re seated. It’s not a step. It’s not a tanning ledge. It’s actual seating inside the water — and once you’ve used one, returning to a pool without it feels like sitting in a chair with no armrests.

They almost never come up in the initial design consultation. Contractors focus on the features homeowners have already seen: waterfall, fire features, tanning ledge, bar stools at a wet-edge counter. Swim-outs are quieter. They don’t photograph dramatically.

But the homeowners who have them talk about them constantly. Because the swim-out solves a problem you don’t know you have until you’ve owned a pool for a summer: there’s nowhere to actually be in your pool without treading water or standing in the shallow end. A swim-out gives you a place to sit and have a conversation, hold a drink, watch your kids, rest between laps, or simply exist in the water comfortably. For anyone who wants to spend time in their pool rather than just swim across it, it’s arguably the highest-value interior feature per square foot you can add.

The confusion is understandable. Both are ledges. Both are built into the pool structure. But they serve completely different purposes.

A tanning ledge — the baja shelf — is typically 6 to 12 inches deep. You’re sitting in a few inches of water, partially in the sun, mostly above the waterline. It’s designed for lounging at the surface.

A swim-out is fully submerged. Standard depth is 18 to 36 inches, depending on placement and how you plan to use it. You’re in the water, seated, with the pool at chest or waist level. It can be positioned in the shallow end, the deep end at an elevated floor, or anywhere along the perimeter where the wall allows for it.

Both can coexist in the same pool. Many of our Lake Norman designs include a tanning ledge at one end and one or two swim-outs along the sides or corners.

Width. Swim-outs need at least 18 inches to be comfortable. Twenty-two to 24 inches is better — wide enough to sit without your back sliding off. Anything narrower becomes a ledge rather than a seat.

Depth. At 18 to 20 inches, the water sits at mid-chest for most adults — comfortable for socializing. At 24 to 30 inches, it’s a deeper soak, more immersive. Talk through what you’re trying to accomplish, because depth is locked in when the shell is shot.

Placement. Corner swim-outs are especially popular — they tuck into the pool’s corner without consuming wall space or interrupting the main swimming area. Some designs run a continuous bench along one entire wall, particularly in pools built for entertaining. A single bench offset to one side is the most common configuration.

Surface. Smooth plaster or quartz aggregate works well on a swim-out. Pebble finishes are textured, which some people find uncomfortable against skin after extended sitting. If you finish the bench in tile — a popular choice for a visual break from the pool floor — confirm it’s rated for submerged use and has a slip-resistant texture.

A single swim-out built into a gunite pool typically adds $1,500 to $3,500 to the base price, depending on size and finish. Corner installations with continuous bench seating can run $4,000 to $7,000. Most of that cost comes from extra concrete and forming during the shell phase.

This is the critical point: swim-outs are not an add-on. They’re structural, designed in and shot with the shell. If you decide you want one after the pool is finished, you can’t have one — not without tearing into finished concrete. No retrofit version exists.

Swim-outs work in almost every pool design, but they’re especially valuable for homeowners who entertain regularly and want a place for guests to gather in the water; families with young kids where a parent wants to be in the pool rather than watching from the deck; anyone with joint issues who needs a place to rest without climbing out; and pools where the layout doesn’t create a natural shallow-end gathering spot.

If your pool will have a spa, a swim-out also gives you a place to cool down between soaks without fully leaving the water — a small detail that changes how much you actually use the pool.

A swim-out is inexpensive when it’s on the blueprint and impossible when it isn’t. That’s the entire argument for adding one — not because it’s dramatic, but because it quietly turns a pool you swim in into a pool you actually live in.
