• Enhance Comfort – Heat-resistant materials keep the deck cool on hot days.
• Increase Appeal – A stylish deck blends with your pool and outdoor space.
• Add Value – Quality decking improves your home’s overall worth.
• Minimise Maintenance – Some materials need less upkeep, saving time and effort.

Popular Pool Decking Options

Choosing the right decking for your precast concrete plunge pool improves both style and function. Each decking material offers different benefits in durability, maintenance, and cost. Below are the most popular options available for Melbourne homeowners.

Quick Decking Comparisons

1. Concrete Decking 

Concrete is a popular choice for decking options for your precast plunge due to its affordability and design flexibility. It can be shaped and textured to create a modern or traditional look.

Pros:

• Highly durable (20–30 years with sealing)
• Very flexible in design (stamping, coloring, exposed aggregate)
• Slip-resistant finishes available. Sealing enhances slip resistance, aligning with the classifications outlined in Australian Standard AS 4586:2013, which provides guidelines for evaluating the slip resistance of new pedestrian surfaces.
• Low-cost compared to stone

Cons:

• Can get very hot under summer sun. “In Melbourne’s hotter months, we often recommend applying a light-colored heat-reflective sealant to concrete decking. It noticeably reduces surface temperature, making it safer and more comfortable around plunge pools.“
• Prone to cracking if ground shifts
• May require resealing every 3–5 years

Best for: Homeowners needing an affordable, durable, and customisable option.

2. Timber Decking

Timber decking adds a natural look that blends well with outdoor spaces, perfect for landscaping around your backyard oasis. Popular choices in Australia, like merbau and spotted gum, offer durability and strong resistance to weather conditions.

Pros:

• Warm, natural look blends well into landscapes
• Can be easily refinished for new looks
• Comfortable underfoot (stays cooler than concrete)

Cons:

• Requires sealing and oiling annually. “Based on our experience working with pool installations in Melbourne’s humid areas, like the Bayside suburbs, we often see that timber decking around pools benefits from resealing every 12 months rather than every 18 months to prevent moisture damage and splitting.“
• Susceptible to termites without treatment

Best for: Homeowners wanting a classic, natural style for their pool area.

3. Composite Decking 

Composite decking combines wood fibers and recycled plastic to give the look of timber with easier maintenance.

Pros:

• No sanding, sealing, or staining required
• Resistant to fading, splintering, rotting
• Wide range of colours and textures
• Often made from recycled materials (eco-friendly). Many composite decking products are made from 95% recycled materials, helping reduce landfill waste, according to Trex Australia.

Cons:

• Higher upfront cost
• Can retain heat in direct sunlight

Best for: Homeowners looking for a durable and low-maintenance solution.

4. Stone Decking 

Stone decking offers a high-end appearance and exceptional strength. Popular choices include travertine, granite, and limestone.

Pros:

• Highly durable and weather-resistant
• Naturally slip-resistant and remains cool underfoot. “In many of the plunge pool projects we’ve been involved with, travertine has proven to be a popular choice for pool surrounds due to its natural coolness underfoot — a valuable advantage during Victoria’s peak summer temperatures.”
• Unique, elegant design options

Cons:

• High material and installation cost
• Requires professional sealing
• Stone can crack with strong ground movement

Best for: Homeowners who want a luxurious and long-lasting pool deck for their precast plunge pools.

5. Paver Decking 

Pavers offer a cost-effective and customizable solution for pool areas. They come in various materials, such as concrete, brick, and natural stone.

Pros:

• Easy to replace individual pavers if damaged around your precast.
• Slip-resistant finishes available
• Wide range of styles, textures, and colors

Cons:

• May shift over time and need re-leveling
• Weeds can grow between pavers if not sealed properly

Best for: Homeowners seeking an affordable and adaptable pool deck.

Common foundation types:

• Concrete slab: Best for concrete, stone, and paver decking.
