One of the most common questions we receive is:
“How much does a new swimming pool cost?”
The honest answer is: it depends.
Unlike pre-moulded shell pools, professionally built concrete swimming pools are custom-engineered structures, and their cost depends on size, access, finishes, equipment, and site conditions.
This guide provides realistic, professional price ranges to help you budget and understand where your money goes.
1. Cost of Building a New Custom Concrete Swimming Pool
A professionally built concrete pool (shotcrete/gunite or hand-packed shell) is a permanent structure designed to last decades. Pricing varies based on:
- Pool size and shape
- Excavation difficulty and soil conditions
- Access to the site (tight access increases labour costs)
- Structural steel reinforcement
- Filtration, plumbing, and electrical systems
- Surface finishes and tiling
- Coping, paving, and landscaping
Typical Professional Price Range (South Africa)
R150,000 – R600,000+ for standard residential pools
R600,000 – R1,500,000+ for premium or large custom pools
What’s Included in a Professional Build
- Engineered concrete shell
- Steel reinforcement and structural integrity
- Filtration system (pump, filter, plumbing)
- Skimmers, main drains, returns
- Basic electrical and lighting
- Pool surface finish (marbelite or fiberglass)
- Coping stones and basic edging
👉 Premium additions such as heating, automation, mosaic bands, infinity edges, water features, and decking are priced separately.
2. Cost of Resurfacing a Pool with Marbelite
Marbelite (also called marcite or plaster finish) is a traditional and durable pool surface. Over time, it becomes rough, stained, or worn and needs resurfacing.
Typical Professional Price Range
R900 – R2,500 per m²
Average residential pool total: R40,000 – R180,000+
What Affects the Price
- Pool size and depth
- Removal of old surface
- Repairs to cracks or hollow areas
- Quality of marbelite mix and pigments
- Acid washing and curing process
When Marbelite Needs Replacing
- Rough, abrasive surface
- Stains that won’t scrub off
- Cracks or delamination
- Frequent algae problems due to porous surface
👉 A properly installed marbelite finish lasts 8 – 15 years with good maintenance.
3. Cost of Fiberglass Resurfacing or Lining
Fiberglass is a premium, low-maintenance finish that creates a smooth, waterproof surface over an existing concrete shell.
Typical Professional Price Range
R1,200 – R3,500 per m²
Average residential pool total: R60,000 – R300,000 +
What’s Included
- Surface preparation and grinding
- Structural fiberglass layers
- Gelcoat or flowcoat topcoat
- Waterproof sealing and curing
Why Fiberglass Costs More
- Labour-intensive installation
- Specialized materials and skilled technicians
- Long lifespan (15 – 25+ years)
- Extremely smooth, algae-resistant surface
👉 Fiberglass is often chosen for premium renovations and long-term maintenance savings.
4. Major Swimming Pool Renovations – What Do They Cost?
Major renovations go beyond resurfacing and may include structural, aesthetic, and equipment upgrades.
Common Major Renovation Work
- Structural crack repairs or shell reinforcement
- Retiling or mosaic bands
- New coping stones or paving
- New filtration systems or pumps
- LED lighting upgrades
- Heating systems (heat pumps or solar)
- Pool shape modifications or depth changes
- Complete aesthetic modernisation
Typical Professional Price Range
R100,000 – R500,000+ for standard renovations
R500,000 – R2,000,000+ for large structural upgrades or redesigns
When Renovation Makes Sense
- Maintenance costs keep increasing
- Surface is beyond repair
- Pool looks outdated or affects property value
- Equipment is inefficient or obsolete
- Leaks or structural movement are present
👉 A professionally renovated pool can add significant value to your property and reduce long-term maintenance costs.
Why Professional Pools Cost More Than Pre-Moulded Shell Pools
Many clients compare custom-built pools to premoulded fiberglass shells. While shell pools are cheaper upfront, they are not the same product.
Custom concrete pools offer:
- Unlimited design and size options
- Stronger structural integrity
- Higher property value
- Premium finishes
- Longer lifespan with proper maintenance
Shell pools are factory-made inserts, while concrete pools are engineered structures built on-site, similar to building a house foundation.
