How to Add a Tanning Ledge to a Pool Design
Last Updated: November 7, 2026
Quick Summary
A tanning ledge is a shallow, flat shelf built along one wall of a pool, usually 6 to 18 inches below the waterline. You can add one during construction or a renovation, or sometimes to an existing pool, depending on the pool type and structure.
- Ledge depth usually ranges from 6 to 18 inches below the water line.
- Shallow 6 to 10 inch ledges suit sitting and toddlers; 16 to 18 inches fits a lounger.
- Fiberglass pools generally cannot take a built-in ledge without compromising the shell.
- Confirm the ledge depth with your pool builder before the shell is built.
- Many jurisdictions require permits for structural, electrical, or drainage changes.

What a Tanning Ledge Is and Why Homeowners Add One
A tanning ledge is a shallow, flat shelf built along one wall of a pool, usually at a depth of about 6 to 18 inches.
Most families add a ledge for comfort. You can sit in the water with your shoulders out, lounge on a sunny afternoon, or let small kids play where they can stand.
Here is what a ledge usually includes:
- A flat surface, typically 12 to 18 inches deep, that sits under the waterline
- A step or seat edge that makes getting on and off easy
- Optional features such as a bubbler, in-water lounger, or umbrella sleeve
The best ledge depends on how you plan to use your pool, so think about that before choosing a size.
Pool Sun Shelf Depth: Choosing the Right Water Depth
Most pool sun shelves sit between 6 and 18 inches below the water line. A shallow shelf works well for small children and for sitting. A deeper shelf fits a lounger better but leaves less room for standing.
Use these guidelines when you choose a depth:
- 6 to 10 inches: Best for sitting with shoulders out and for toddlers
- 12 to 14 inches: Good all-purpose depth for most adults
- 16 to 18 inches: Fits a lounger, but you may need to step down to reach it
Check the depth of the rest of the pool too. A ledge that is too deep can feel awkward if the rest of the pool is shallow.
Can You Add a Sun Shelf to an Existing Pool?
Yes, you can often add a sun shelf to an existing pool, but the answer depends on the pool type and its structure. Some pools can be modified with a removable or added-on ledge. Others cannot be changed without major work.
A few questions will guide your decision:
- Is the pool shell structurally sound, with no major cracks or movement?
- Is there enough space along the wall where the ledge would sit?
- Will the new shelf affect drainage, circulation, or the pool's water volume?
If the answers are mostly positive, an add-on ledge is usually the simpler route. If the pool has problems, fix them first.
Retrofit Decision Tree: Concrete, Fiberglass, and Vinyl Liner Pools
Your pool type determines not just how a ledge is added but whether it is practical at all. Use this decision path to understand what each construction type can and cannot support before you call a contractor.
Concrete (Gunite) Pools
A concrete pool has a steel-reinforced shell coated with plaster or an aggregate finish. Because the shell is built on site, a tanning ledge can usually be added during a renovation by forming and pouring new concrete that ties into the existing wall and floor with dowels or rebar.
- Feasible when: The shell is sound, the wall has adequate reinforcement, and you are already planning a replaster or major renovation.
- Requires major reconstruction when: The existing wall is cracked, the pool has movement or settlement, or the ledge would cantilever beyond what the shell can support without added footings.
- Impractical when: The pool is near the end of its structural life or the cost of structural repair exceeds the value of the addition.
Fiberglass Pools
A fiberglass pool is a molded shell, so you cannot cut into it and pour a new shelf without compromising the shell and its warranty. A built-in ledge is generally not an option for a fiberglass shell.
- Feasible when: You accept a non-structural, add-on solution and the pool floor is flat enough to support it.
- Requires major reconstruction when: Never for a true built-in ledge; the shell would have to be replaced.
- Impractical when: The shell manufacturer's warranty prohibits attachments or the pool has a sloping floor that will not seat a removable unit safely.
Vinyl Liner Pools
A vinyl liner pool has a steel or polymer wall frame and a sand or vermiculite floor covered by a liner.
- Feasible when: The wall frame is sound and you are willing to replace the liner as part of the project.
- Requires major reconstruction when: The wall panels are corroded or the floor needs reworking to support the new frame.
- Impractical when: The pool is older and the frame is failing, since the ledge project would trigger a full pool renovation.
Watch out: a contractor who quotes a built-in ledge for a fiberglass pool without explaining the shell and warranty implications is a red flag, get a second opinion before signing.
The Quick Decision Test
Ask three questions in order: (1) Is the shell structurally sound? (2) Does the pool type allow a built-in structure without voiding a warranty? (3) Are you already planning a finish or liner replacement? If the answer to the first is no, fix the structure first. If the second is no, choose a removable alternative. If the third is no, factor the added finish or liner cost into your budget before committing.
Step-by-Step Project Sequence, Timeline, and Cost Drivers
A ledge project follows a predictable sequence, but the time and cost at each stage depend heavily on your pool type and whether you are already renovating. Here is the realistic order of work and what drives the budget at each step.
Project Sequence
- Structural inspection and feasibility assessment. A qualified contractor evaluates the shell, wall reinforcement, and pool type. This step determines whether you pursue a built-in ledge or a removable alternative.
- Design and layout. Choose the ledge depth (6 to 18 inches), width, shape, and features such as bubblers, umbrella sleeves, or in-water loungers. Design decisions here lock in the structural and plumbing work that follows.
- Permitting and approvals. Many jurisdictions require a permit for structural changes to a pool, for electrical work tied to bubblers or lighting, and for drainage changes. Confirm requirements with your local building department; approval timelines vary widely by jurisdiction.
- Site preparation and drainage. The pool is drained, the work area is protected, and any temporary shoring is installed. For concrete pools, the existing finish is removed where the new structure ties in.
- Structural work. For concrete pools, forms are built, rebar is tied into the existing shell, and concrete is poured. For vinyl pools, a frame is built inside the pool and the floor is prepared. For fiberglass pools, a removable or bolt-on unit is fitted instead.
- Plumbing and water features. Bubblers, return lines, and any lighting conduit are run before the finish goes on. This is the stage where circulation and drainage integration is decided.
- Finish work. Plaster, aggregate, tile, or a new liner is applied over the new structure. For vinyl pools, the liner is measured, cut, and installed.
- Refill, test, and reopen. The pool is refilled, the system is checked for leaks, and water chemistry is balanced before use.
Timeline Expectations
Structural repairs or permit delays can extend any timeline. For a project schedule specific to your pool, contact Howland Pools.
Cost Drivers
Pricing depends on pool type, size, and site access. For current prices or a quote, contact Howland Pools. The main drivers are:
- Design and engineering: Structural drawings and layout work, especially for cantilevered or elevated ledges.
- Structural modification: Demolition, rebar, concrete, and any added footings. This is usually the largest single cost for concrete pools.
- Plumbing and water features: Bubbler lines, return adjustments, and electrical work for lighting.
Ask for a written quote that separates these categories so you can compare bids fairly. A quote that lumps everything into one number makes it hard to see where the real cost is.
Watch out: a bid that omits liner replacement for a vinyl pool or omits finish restoration for a concrete pool is incomplete, those costs do not disappear, they just show up later as change orders.

The table below summarises the main cost categories a contractor should itemise, as described in the project sequence.
| Cost driver | What it covers | Note |
|---|---|---|
| Design and engineering | Structural drawings and layout work | Especially for cantilevered or elevated ledges |
| Structural modification | Demolition, rebar, concrete, added footings | Usually the largest single cost for concrete pools |
| Plumbing and water features | Bubbler lines, return adjustments, lighting electrical | Decided before the finish goes on |
| Finish and tile | Plaster, aggregate, liner, slip-resistant tile | Applied over the new structure |
| Liner replacement | Custom-cut liner for vinyl pools | A required line item, not optional |
| Restoration | Refilling, water treatment, landscaping, deck patching | Often overlooked in early bids |
Removable Sun Shelf Options and Design Ideas
A removable sun shelf is a good choice if you want the option of a ledge without permanent construction. These units sit on the pool floor and can be lifted out for the off-season or when you need the full depth.
Common options include:
- Removable frames: Lightweight units that rest on the pool floor
- Loungers: In-water chairs that fit on a shelf
- Umbrella sleeves: Built-in holders for shade
Tanning Ledge Pool Design Ideas and Permit Considerations
Good design makes the ledge useful and safe. Consider these ideas:
- Add a bubbler or water feature along the ledge for sound and comfort
- Place the ledge on the sunny side of the pool for longer use
- Use slip-resistant tile on the top surface
Permits matter too. Many areas require approval for changes to a pool's structure, electrical work, or drainage. Confirm the rules with your local building department before construction starts. Contact Howland Pools to discuss what your project may need.

Frequently Asked Questions
Can you add a tanning ledge to an existing pool?
In many cases, yes, but feasibility depends on the pool type and the structure of the shell. Concrete and gunite pools may be modifiable, while fiberglass shells often cannot be altered without compromising the structure. Vinyl liner pools can sometimes accommodate a ledge with a custom liner, though the liner must be fabricated to fit the new shape. A structural inspection by a qualified pool contractor is the only reliable way to confirm whether a ledge can be added to your specific pool.
How deep should a tanning ledge be in a pool?
Most tanning ledges sit between 6 and 18 inches below the waterline, which keeps the top of the ledge shallow enough to sit or lie on while the body stays submerged. The exact depth depends on how you plan to use the ledge and the overall depth of the pool. Keep the ledge deep enough that it does not become a hazard for swimmers, and confirm the final depth with your contractor so the water level and pool safety requirements align with your design.
Where should a tanning ledge be placed in a pool design?
Tanning ledges are typically placed along a side wall in the shallow end, where the sun reaches the water for most of the day. Placing the ledge near the entry steps makes it easier to access. Consider the direction the pool faces, existing shade from trees or structures, and how the ledge will connect to circulation and any water features. Your pool designer can review sun exposure and drainage before the layout is finalized.
Do you handle permits for a pool with a tanning ledge?
Permit requirements for adding a ledge vary by municipality, and Contact Howland Pools for information on the permit process for your property. Structural changes to an existing pool usually require review because they affect the shell and drainage. Ask Howland Pools directly for current permit requirements and whether they manage the permitting process for your project.
