Most pool owners don't realize until after the concrete is poured that their pool's shallow end is fixed forever. It's built into one corner at the time of construction, and that's where it stays — for decades.
If you've ever wished you had more shallow space — a place for your kids to stand, a wading zone for a party, or just somewhere to sit in the water without floating — you've probably hit the same wall: traditionally, you can't add a shallow end to a pool without tearing it apart.
That's starting to change.
Why Pool Shallow Ends Are Fixed (And Why It's a Problem)
When a pool is built, the shallow end is a structural feature. The floor slopes from a deep end (usually 8–10 feet) up to a shallow end (typically 3–3.5 feet) at one end of the pool. That geometry is set in concrete — literally.
For most families, this means the shallow end is wherever the builder put it, oriented however the builder oriented it, at whatever depth they chose. If it's in a shady corner, faces the wrong direction, or is too deep for your toddler to stand comfortably, there's nothing you can do about it.
At least, there wasn't.
The Traditional Options (And Why They Fall Short)
If you want more shallow water in your pool, your options have been limited:
Pool renovation — A contractor can re-pour the pool floor to extend or relocate the shallow end, or add a tanning ledge. Cost: $8,000–$35,000. Time: weeks of downtime. Permits required. Completely irreversible.
Pool steps and benches — Built-in ledges and sun shelves can provide some shallow standing space, but they're fixed, limited in area, and expensive to add after the fact.
Inflatable platforms — Typically $100–$500. Cheap floats and inflatables that create a soft, unstable surface. They shift, deflate, and aren't designed to be stood on safely.
Cost figures above are typical U.S. contractor estimates; costs vary by region and scope.
None of these actually solve the problem. They're either too expensive, too permanent, or not a real solution at all.
The New Way: A Depth-Adjustable Shallow Water Platform
Shallo™ is a rigid, modular platform that mounts to your pool edge and creates a stable, shallow-water zone wherever you want it — no construction, no permits, no permanent modifications to your pool.
Here's how it works: weighted ballast tanks — you fill them with water or sand — sit on top of the pool edge and act as a counterweight, holding the platform suspended in the water at whatever depth you choose. It does not rest on the pool floor, and it doesn't float freely. The ballast is what holds it. The platform extends 4 feet into the pool, and depth is set by a patent-pending ladder-rack and locking-pin system, adjustable from water level down to about three feet. The deck surface is non-slip and comfortable underfoot even when wet.
Shallo is built from marine-grade, corrosion-resistant materials chosen for both salt and fresh water. We're still finalizing the exact material spec, and we'll publish it before pre-orders open.
Initial assembly takes an afternoon with basic hand tools — a screwdriver and an allen wrench. That's a one-time job. After that, changing the depth takes seconds and no tools at all: pull the pin, set the height, drop the pin back in.
Because it anchors over the edge rather than modifying the pool structure, it works with every pool type — concrete, fiberglass, and vinyl liner — and protective bumpers on the frame prevent any contact damage to the pool surface.
What You Can Do With It
Stand in the deep end. The most common use case. Dad is standing in the deep end holding a drink while the kids play around him. That moment doesn't happen without a platform.
Create a toddler wading zone. Set the depth to ankle- or knee-deep and you have a controlled, stable wading area where small children can play safely — right next to the adults in the water.
Add a social gathering spot. Each unit includes a built-in backrest and armrest. Adults can sit in the water, lean back, and actually relax instead of treading water or clinging to the wall.
Expand the setup. The base unit is a 4x4 ft platform. Multiple units connect side by side — each with its own ballast tank — so you can build a 4x8, an 8x8, or a run along your pool edge. The platform always extends 4 feet into the water, so you get a shallow ledge as long as the number of units you add.
Who This Is For
Families with young children — The most common reason people want more shallow water is simple: they want their kids to stand safely. Shallo lets you dial in the exact depth — ankle-deep for a toddler, knee-deep for an older kid — and create a supervised wading zone anywhere in the pool, in the deep end or anywhere else.
Entertainers — If you host pool parties, a platform in the deep end creates a gathering spot where adults can stand, sit, and socialize without treading water. The built-in bumper bar accessory adds a flat surface for drinks and food.
Anyone with a deep pool — Many older pools were built with very little shallow space. A 3.5-foot shallow end isn't actually comfortable for most adults to stand in. Shallo lets you create a true wading depth that the original pool never had.
Frequently Asked Questions
Can you actually add a shallow end to an existing pool?
Yes — with a depth-adjustable platform like Shallo, you can create a shallow-water zone at any point along your pool edge without modifying the pool structure. No renovation required.
How shallow can you make it?
Shallo adjusts from water level down to about three feet, using a patent-pending ladder-rack and locking-pin system. Set the depth, drop the pin, and it locks in place.
Does it damage the pool?
No. Shallo mounts to the pool edge and is held in place by weighted ballast tanks filled with water or sand. It never rests on the pool floor. Protective bumpers on the frame prevent contact damage to the pool surface. It works with concrete, fiberglass, and vinyl liner pools.
Is it safe for kids?
Yes. The platform is rigid — not an inflatable — with a non-slip deck surface that stays stable and grippy when wet. The optional bumper bar accessory also creates a barrier at the front edge to keep small children from sliding off into deeper water.
Do I need tools to install it?
Initial assembly takes an afternoon with a screwdriver and an allen wrench — a one-time setup. After that, adjusting the depth takes seconds and no tools at all.
How much weight does it hold?
We're not going to guess at that number. Shallo is in load testing now, and we'll publish verified ratings before pre-orders open. We'd rather give you a figure we can stand behind than a marketing number.
What is it made of?
Marine-grade, corrosion-resistant materials chosen for both salt and fresh water. The final material spec isn't locked yet, and we'll publish it before pre-orders open.
