Replastering a pool is a major renovation; buyers typically see price ranges driven by finish choice, surface area, and labor. The cost estimate below uses a 20×40 foot pool as a baseline and highlights key factors that affect total spending. Prices shown assume standard gunite or concrete pools with typical coping and decking nearby.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Total project | $7,000 | $12,000 | $20,000 | Assumes standard finish and basic prep |
| Per sq ft | $4 | $8 | $15 | Surface area roughly 700–900 sq ft of plaster |
| Finish options | $2,000 | $4,000 | $9,000 | Basic plaster vs premium finishes |
| Labor | $3,000 | $6,000 | $12,000 | Crew time and inspection work |
| Materials | $1,500 | $3,000 | $6,000 | Plaster mix, bonding agents, sealers |
| Equipment & prep | $500 | $1,500 | $4,000 | Scaffolding, plastering tools, water test |
| Permits & fees | $0 | $200 | $1,000 | Depends on local rules |
| Delivery & disposal | $200 | $800 | $2,000 | Debris handling and materials transport |
Overview Of Costs
Cost range for replastering a 20×40 pool typically falls between 7,000 and 20,000 dollars. The main drivers are surface area to cover, finish quality, and labor efficiency. A mid range project often lands near 12,000 dollars, with higher totals if premium finishes or extensive surface repairs are required. Assumptions include standard gunite construction, accessible site, and no major structural issues.
Cost Breakdown
The following table shows how a typical replastering project may break down, with totals and per unit references. Assumptions cover region, pool shape, and crew rates.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | 1,500 | 3,000 | 6,000 | Plaster mix, sealers, bonding agents |
| Labor | 3,000 | 6,000 | 12,000 | Hours x crew rate |
| Equipment & Prep | 500 | 1,500 | 4,000 | Scaffolding, prep work |
| Permits | 0 | 200 | 1,000 | Local requirements |
| Delivery/Disposal | 200 | 800 | 2,000 | Waste handling |
| Finish Type | 2,000 | 4,000 | 9,000 | Basic plaster vs quartz/pebble |
Pricing Variables
Costs hinge on several factors. Finish quality drives major cost variation, from traditional plaster to premium quartz or glass bead surfaces. Surface area and access influence labor efficiency; larger or awkward shapes add hours. Assumptions: region, specs, labor hours.
Ways To Save
Smart planning can trim expenses without compromising durability. Shop quotes from multiple installers to compare scope and warranties. Scheduling during slower seasons can lower labor rates. Consider mid range finishes if budget is tight, while ensuring proper preparation to extend pool life.
Regional Price Differences
Prices vary by market. In the Northeast, higher labor costs can push totals toward the upper end of the range, while the Southwest may offer lower rates for similar finishes due to climate and demand. Urban markets often run higher than suburban or rural areas, reflecting crew availability and permitting processes. Expect regional deltas of roughly ±15–25 percent depending on finish and site access.
Labor & Installation Time
Typical replaster work for a 20×40 pool spans several days. A basic scope may require 2–3 days, while premium finishes can take 4–6 days with curing time. Labor hours and crew size are the dominant cost drivers, and scheduling around warm, dry weather can help avoid delays.
Additional & Hidden Costs
Hidden fees can appear if repairs are needed beyond plaster. Extra work may include surface patching, coping replacement, or deck restoration. Permits, inspections, and utility coordination can add to the total. Budget a contingency of 5–10 percent for unforeseen issues.
