Pool Remodeling: Cost, Structural Changes, and Design Ideas
Last updated 2026-07-30
Pool remodeling means changing the structure of an existing pool — reshaping the shell, adding depth, expanding the footprint, or integrating new features that require structural modifications. It is different from renovation, which is cosmetic. Remodeling is major surgery; renovation is a facelift. Here is what you can change, what it costs, and how to know which one your pool needs.
Remodeling vs Renovation: What's the Difference
The distinction matters because the cost, timeline, and permit requirements are different.
Remodeling changes the pool's structure. You are cutting into, adding to, or modifying the concrete shell. Examples: converting a deep end into a shallow lounge area, adding a baja shelf, widening the pool, changing the depth profile, or integrating an attached spa where one did not exist before. Remodeling requires structural engineering, a building permit, and 4 to 12 weeks of construction.
Renovation updates the pool's surface and equipment without changing the structure. Examples: resurfacing the interior finish, replacing tile and coping, upgrading the pump and filter, or adding a salt system. Renovation is faster (1 to 3 weeks) and less expensive. If the shell stays intact, it is renovation. If the shell is modified, it is remodeling.
What Can Be Remodeled
Adding a Baja Shelf or Tanning Ledge
A baja shelf is a wide, shallow platform — 6 to 9 inches of water — built into one end of the pool. Adding one to an existing pool requires cutting into the shallow-end shell, forming the shelf, tying new rebar into the existing framework, and spraying new gunite. Cost: $5,000 to $12,000. Timeline: 2 to 3 weeks.
Beach Entry Conversion
Converting traditional steps into a gradual beach entry slope requires reshaping the shallow end of the pool. The existing steps are demolished, the shell is extended outward, and a new sloped floor is formed and sprayed. Cost: $8,000 to $20,000 depending on pool size and slope length. Timeline: 3 to 5 weeks.
Depth Changes
Making a pool shallower (filling in a deep end) or deeper (excavating further) requires modifying the floor of the shell. Making it shallower is simpler — the deep end is partially filled with gravel and a new floor is poured over it. Making it deeper is more complex — the existing floor must be demolished, deeper excavation is needed, and a new floor is formed. Cost: $5,000 to $15,000. Timeline: 2 to 4 weeks.
Spa Integration
Adding an attached spa to an existing pool requires cutting into the shell to create a connecting wall, forming the spa bowl, and running separate plumbing for the spa jets, heater, and blower. Cost: $15,000 to $30,000. Timeline: 4 to 8 weeks. This is the most complex structural remodel — it involves new plumbing, new equipment, and structural integration with the existing shell.
How Much Does Pool Remodeling Cost
| Project | Cost Range | Timeline |
|---|---|---|
| Add baja shelf | $5,000–$12,000 | 2–3 weeks |
| Beach entry conversion | $8,000–$20,000 | 3–5 weeks |
| Depth change (shallower) | $5,000–$10,000 | 2–3 weeks |
| Depth change (deeper) | $10,000–$15,000 | 3–4 weeks |
| Pool expansion (wider/longer) | $15,000–$40,000 | 4–8 weeks |
| Spa integration | $15,000–$30,000 | 4–8 weeks |
| Full reshape (multiple changes) | $30,000–$50,000+ | 8–12 weeks |
These are structural costs only — they do not include resurfacing, which is typically done as part of the remodel after the structural work is complete. If you are remodeling the shell, plan to resurface the entire pool at the same time. The new gunite sections must be finished to match the existing surface, and it is more cost-effective to resurface everything in one pass than to patch the new sections and resurface later.
Timeline and What to Expect
Remodeling follows the same sequence as new construction but on a smaller scale. Demolition comes first — the section being changed is cut out or jackhammered. New rebar is tied into the existing framework. New gunite is sprayed and cured for 7 days. The entire pool is then resurfaced so the new and old sections match. Equipment and plumbing modifications happen concurrently. Total: 4 to 12 weeks depending on scope.
The pool will be out of service for the entire duration. Plan your remodel for the off-season when you would not be swimming anyway.
Frequently Asked Questions
What is the difference between pool remodeling and renovation?
Remodeling changes the pool structure — reshaping the shell, adding features, changing depth. Renovation updates the surface and equipment — resurfacing, new tile, new pump. If you are cutting into concrete, it is a remodel. If the shell stays intact, it is a renovation. Remodeling costs more and takes longer because structural modifications require engineering and curing time.How long does pool remodeling take?
Four to 12 weeks depending on scope. Adding a baja shelf takes 2 to 3 weeks. A full reshape with multiple structural changes takes 8 to 12 weeks — comparable to building a new pool. The pool is out of service for the entire duration.Can you remodel a fiberglass pool?
No — fiberglass pools are single-piece shells that cannot be structurally modified. If you want a different shape or features in a fiberglass pool, the only option is removal and replacement. Concrete pools are the only type that can be remodeled because the shell can be cut into and reshaped.Pool Remodeling in Your Area
