When buyers weigh up plunge pool materials, precast concrete sits in a distinct position. It delivers the tiled finish and visual weight of a traditional concrete pool, but arrives fully formed rather than poured and cured on-site. For Perth homeowners who want a permanent, integrated pool with a high-end finish without months of on-site construction, precast is worth understanding properly before requesting quotes.
This guide covers how precast pools are made and installed, what the three options in the precast concrete pool range at West Coast Plunge Pools each offer, and how precast compares to fibreglass and stainless steel on the factors that matter most to buyers.
What Precast Concrete Actually Means
Precast is not the same as poured concrete. A poured concrete pool is formed, reinforced, and cured on your property over several weeks. A precast pool is manufactured in a controlled factory environment, cured under stable conditions, and delivered to site as a finished reinforced concrete shell.
Factory curing produces consistent concrete strength without the variables of on-site weather or contractor scheduling. How precast pools are installed covers the full process, but the headline for buyers is that most Perth precast installations are completed within weeks of site start once approvals are in place, which is considerably faster than poured concrete.
The shared characteristics across all precast concrete pools include:
- Reinforced concrete shell manufactured off-site to strict tolerances
- Crane placement required to lower the shell into the excavated pit
- Tiled or treated interior finish depending on the brand
- Thermal mass of the concrete provides good heat retention once water reaches temperature
- Permanent, in-ground installation. Precast pools are not designed to be relocated
The Three Precast Ranges at WCPP
West Coast Plunge Pools carries three distinct precast concrete pool brands, each with a different structural approach, finish profile, and model range.
Allcast
The Allcast precast range is the broadest of the three, covering six models across circular, square, and rectangular shapes.
Model | Shape | Size | Notes |
Harmony | Circular | ~2.5m diameter | Smallest in range; installs 1,200mm above ground, can in some configurations reduce or eliminate pool fence requirement |
Bliss | Circular | 3.5m diameter | Available in three heights: 1.43m, 1.63m, 1.83m |
Haven | Circular | 4.5m diameter | Three heights; optional standing ledge on deeper models |
Eden | Circular | 4m diameter | Three heights; optional standing ledge on deeper models |
Zen | Square | Compact | Fully tiled; suited to courtyards and geometric outdoor designs |
Oasis | Rectangular | Largest in villa range | Fully tiled; optional standing ledge |
Wet Edge
The Wet Edge pool range is engineered in Melbourne and available for in-ground, half in-ground, and above-ground installations.
Key characteristics are:
- Ceramic and glass tiling options across the range
- Fully waterproofed construction
- Design options include infinity edge and wet deck with concealed gutter configurations
- Suited to buyers who want a high-specification finish or a specific edge detail
West Coast Sphinx
The West Coast Sphinx is described as the first of its kind in Australia. It uses a full concrete structure inside and out, with no tiling or additional coatings required. Key characteristics:
- Full concrete interior and exterior, with no tiling, no render, and no additional surface treatment
- Eliminates grout lines and the resurfacing considerations of a tiled finish
- Suits buyers who want a raw concrete aesthetic or prefer to avoid tiled maintenance
The Installation Process
Precast concrete pool installation follows a consistent sequence across all three ranges. Understanding each step helps buyers assess access requirements and timeline before committing to a model.
- Design and approvals: Select your model and finishes. A council building permit and safety barrier approval are required before installation can begin.
- Site preparation: Excavation to the pool shell dimensions and base preparation for a level foundation.
- Delivery and crane placement: The finished concrete shell is transported to site and lowered into the excavated pit by crane. Adequate crane access from the street to the installation area must be confirmed before ordering.
- Plumbing and filtration: All plumbing connections, filtration, and sanitisation systems are installed and tested.
- Finishing touches: Decking, coping, lighting, and any additional equipment are completed.
Pool dimension and site planning guidance covers how to assess site access and yard layout before selecting a model. Most Perth residential precast installations are completed within a month of site start, depending on crane access, soil conditions, and council approval timing.
Finish and Tile Options
The finish of a precast concrete pool is one of its primary points of difference from fibreglass and stainless steel. Fibreglass pools have a gelcoat interior in a limited range of colours, and stainless steel has a single brushed steel finish. Precast concrete pools, particularly the Allcast and Wet Edge ranges, are tiled, which opens up a wide range of colour, texture, and pattern options.
Ceramic tiles are durable and widely used. Glass tiles provide a higher-end reflective finish, and grout lines require periodic cleaning to prevent algae if water chemistry drifts. The design and finish options at WCPP cover tile colours, coping styles, and other finish choices available across the range.
For buyers who want to avoid tiled maintenance entirely, the West Coast Sphinx offers a full concrete finish as an alternative.
Keeping Your Precast Concrete Plunge Pool in Top Condition
Precast concrete pools require regular water chemistry management, filtration maintenance, and periodic tile and grout inspection. A pH that drifts too low can affect grout and tile adhesion over time, so water balance monitoring is more involved than for a fibreglass or stainless steel pool.
UV sanitisation can reduce the chemical load on any pool finish, including concrete. Smaller plunge pool volumes keep ongoing chemical costs manageable regardless of surface material.
WA Compliance
Precast concrete pools are subject to the same WA pool safety requirements as all other pool types. A building permit is required under the Building Act 2011 for any pool holding more than 300mm of water, and a compliant safety barrier must be in place before filling.
WA pool fencing requirements apply from the point of installation. A Cottesloe homeowner selecting a larger Allcast model such as the Haven or Eden would need to confirm fencing placement relative to the pool position and any outdoor living areas before finalising the site layout.
Precast vs Fibreglass vs Stainless Steel
Factor | Precast Concrete | Fibreglass | Stainless Steel |
Finish | Tiled or full concrete | Gelcoat, limited colours | Brushed steel |
Installation | Crane required, in-ground | Crane for in-ground; above-ground options available | Above-ground, no excavation |
Timeline | Weeks once on-site | Days to weeks | Days |
Heat retention | Good: thermal mass of concrete | Good: some natural insulation | Moderate: cover recommended |
Maintenance | Regular tile and grout care | Lower: non-porous surface | Low: inert material, no surface treatment |
Relocatable | No | Some models yes | Yes |
Suits sloped sites | Confirm per model | Some above-ground models suit slopes | Yes |
WA compliance | Permit and safety barrier required | Permit and safety barrier required | Permit and safety barrier required |
Is Precast Concrete Right for Your Yard?
Precast concrete suits buyers who want a permanent, integrated pool with a tiled finish and a site that has adequate crane access. It is worth considering if:
- A tiled pool finish that matches your outdoor aesthetic is a priority
- The pool will be a permanent feature and relocation is not a consideration
- Your block has clear crane access from the street to the installation area
- You want a pool that integrates flush with decking or paving for a built-in look
- You are comfortable with the maintenance requirements of a tiled surface
It is generally less suited to buyers who need fast installation with minimal site disruption, have restricted crane access, or are working with a tighter budget where self-supporting fibreglass may be more practical.

Frequently Asked Questions
Most Perth precast pool installations are completed within two to four weeks after site preparation, depending on crane access, soil conditions, and finishing details. This is considerably faster than a poured concrete pool, which requires on-site forming, pouring, and curing before tiling can begin. Approval timelines vary by council and are separate from the installation period.
Yes. Precast concrete pool shells are heavy reinforced units that require crane placement into the excavated pit.
Confirming crane access from the street to your intended pool position is one of the first practical checks before selecting a precast model. If crane access is restricted, self-supporting fibreglass or stainless steel options may be more practical for your site.
The Allcast and Wet Edge ranges are tiled pools with ceramic or glass tile options. The West Coast Sphinx is different. It has a full concrete structure inside and out with no tiling or additional coatings required.
Buyers who prefer to avoid tiled maintenance should consider the Sphinx, or discuss the untiled concrete finish with the West Coast Plunge Pools team.
Precast concrete delivers a tiled finish and a permanent integrated result that fibreglass cannot replicate. Fibreglass offers a non-porous surface that requires less chemical maintenance and is available in self-supporting above-ground configurations that precast is not. The right choice depends on the finish you want, your site access, and whether permanence or flexibility is the priority.
The plunge pool beginner’s guide covers all three main pool materials in plain language before you start comparing specific models. For buyers who have already decided on precast, contacting the West Coast Plunge Pools team with your site dimensions and crane access details is the most efficient next step.
