Shallo™ Dock vs. Tanning Ledge: What's the Difference?
If you've been searching for a way to get more shallow water in your pool, you've probably landed on one of two solutions: a tanning ledge (also called a Baja shelf or sun shelf) or a depth-adjustable platform like the Shallo™ Dock.
They solve the same problem. They do it very differently.
What Is a Tanning Ledge?
A tanning ledge is a shallow, flat platform built directly into a pool during construction — or added as part of a renovation. It typically sits at 6 to 12 inches below the water's surface and spans 4 to 8 feet wide.
It's where you put a chaise longue, let toddlers wade, or just sit in the water without floating. It's a popular feature, and for good reason — when it's built right, it's beautiful and functional.
The catch: it's permanent, expensive, and fixed.
- Adding one to an existing pool requires draining the pool, structural modification, and resurfacing. Pool renovation to add a tanning ledge typically runs $8,000–$35,000.
- It sits in one location forever — wherever it was built.
- The depth is fixed at construction. You can't adjust it for different ages or uses.
- If you move, it stays.
Cost figures throughout this article are typical U.S. contractor estimates; costs vary by region and scope.
What Is the Shallo™ Dock?
The Shallo™ Dock is a rigid, modular platform that mounts to the edge of your existing pool — or to a lake dock — and is held in place by weighted ballast tanks you fill with water or sand. It does not rest on the pool floor, and it does not float freely. It creates a stable, shallow-water zone at whatever depth you want, anywhere from water level down to roughly 3 feet. No construction. No renovation. No draining.
You position it where you want it along the edge. You set the height to whatever depth works for your family today. When the season ends, you take it out. When your kids are a few years older, you move it to a new depth.
Initial assembly takes an afternoon with basic hand tools — a screwdriver and an allen wrench — and it's a one-time job. After that, depth adjusts in seconds with no tools, using a patent-pending ladder-rack and locking-pin system. The base unit is 4 × 4 feet, and units connect into larger configurations.
It's built from marine-grade, corrosion-resistant materials chosen for both salt and fresh water. The final material spec will be published before pre-orders open.
It's the first product in the Shallow-End Systems™ category — a purpose-built alternative to built-in pool features that require commitment you can't undo.

| Cost | $8,000–$35,000 | Not yet announced — pricing published when pre-orders open. |
| Depth | Fixed at construction | Adjustable from water level to approximately 3 feet |
| Location | Fixed where built | Mounts to any pool edge or dock edge |
| Reversible | No — permanent | Yes — removable any time |
| Works in lakes | No | Yes |
| Works in existing pools | Only with renovation | Yes, any pool, no modification |
| Maintenance | Part of pool structure | Rinse and store |
What About Inflatable Platforms?
Inflatable platforms are the cheapest option at roughly $100–$500, and they're easy to store. But they flex underfoot and drift with wind and waves, so they don't give you a surface you can reliably stand on — which is the whole point of a shallow end.
When a Tanning Ledge Makes More Sense
If you're building a brand-new pool and you have a specific vision for how it will look — and budget for the feature — a tanning ledge is a beautiful option. It's seamless, architectural, and built-in.
If you're renovating anyway and you've always wanted one, add it.
But if you already own a pool and you're not planning a renovation, a tanning ledge isn't a realistic option. The construction cost and disruption don't make sense just to add shallow water.
When the Shallo™ Dock Makes More Sense
The Shallo™ Dock is the right choice if:
- You have an existing pool and want shallow water without renovation
- You have a lake or pond with a dock and want a wading zone
- You want flexibility — depth, location, seasonality
- You have kids at multiple ages or stages who need different depths
- You want to be able to move it, reconfigure it, or take it with you if you move
It's also the only option that works across both pools and natural water — which means one system handles every waterfront situation you encounter.

The Bottom Line
A tanning ledge is a permanent architectural decision. The Shallo™ Dock is a flexible, reversible system you control.
They solve the same problem. One locks you in. The other doesn't.
