Your 10 Step Guide To How A Luxury Indoor Pool Is Built

Wondering about how to build a luxury indoor pool?

As a leading indoor swimming pool contractor, Starpool are experienced with every construction method on the market. From our findings, we recommend concrete pool shells for indoor swimming pools. The benefits of sprayed concrete swimming pool shells outweigh all other options.

Typical timeframes for building your pool shell, waterproofing, curing and services installation typically range between 12-16 weeks (not including the commissioning stage).

Here’s how we’ll go about building your pool in accordance with your design specification.

1) Constructing Your Pool Shell

Starpool will initially confirm the finish floor level for your home indoor swimming pool.  We will use this as our datum in conjunction with construction drawings to set out swimming pool dimensions.

Once the exact size and positioning requirements of your pool have been confirmed, your contractor will excavate the feature space in preparation for your pool build.

2) Shutter System and Steel Cage

We will build a temporary shutter system from plywood, which will form four insulating walls for the pool walls and floor.

We’ll then create a steel-reinforced cage based on structural design calculations for your home pool. This will be protected by the shutter system.

3) Fittings and Lights

Fittings are inserted into the steel cage before concrete spraying can go ahead.  The steel cage will contain all your specified fittings and light niches for your indoor pool. These might include:

  • pipe fittings
  • vacuum fittings
  • return water inlets
  • filtration systems
  • colour evolution LED lighting

All fittings are covered for protective purposes.

4) Concrete Spraying

The next stage involves a complete re-check of all dimensions against the pool construction drawings. Once these have been signed off, we’ll begin shotcrete concrete spraying of the swimming pool shell. The concrete will form against the steel, reinforcing your pool structure.

5) Curing

From start to completion, the construction of your pool shell will take between 2 and 5 weeks, depending on dimensions and complexity of pool design.

Once the shell is completed, we’ll leave it to cure for a minimum of 4 weeks.  While the shell is curing, we’ll install UPVC pipework from the pool to the plant room.

6) Waterproof Coating

The next phase of your swimming pool construction is to waterproof the pool shell. We use a factory pre-mixed render to guarantee a consistency that cannot be achieved through on-site mixing.

At Starpool, we recognise the importance of the waterproof layer.  We use Sika One 3-part, pre-bagged render systems.  These control water ingress and create a hard-wearing screen that withstands high water pressure and follows the contours of your pool structure.

Sika Render

  • Provides a waterproof finish that is recognised as the best cement-based waterproofing system for swimming pools
  • Has a 100-year track record of high-quality results
  • Can be used to achieve grades 1-3 according to BS 8101-2009
  • Is suitable for high water table according to BS 8102-2009
  • Is drinking water inspectorate approved (ref no. 56.4.94)
  • Is BBA approved
  • Offer a guarantee when installed by a registered contractor, such as Starpool
7) Second Waterproof Coating

Once the waterproofing render has cured, we add a second waterproof layer in the form of world-leading Ardex S7 plus or Mapelastic, which is designed specifically for the waterproofing of indoor swimming pools.  Once applied, a static water test will be applied to ensure the pool shell is completely watertight.

8) Luxury Tiling

Upon completion of the static water test, we will leave your pool shell to dry again, before finishing it with final features and tiling.  We’ll tile your luxury pool based on your choice from our extensive range of show-stopping tile designs.  We’ll even design family emblem tiling for an absolute sense of grandeur in your home pool.

9) Installation Services

While your pool shell is being constructed, we’ll begin the primary phase of your heating and ventilation system.  It’s important that air temperature and humidity is regulated in your indoor pool space, which is why we carry out AVC work to ensure that the air in your pool space is healthy and plentiful.

Ventilation and heating systems involve installation of ductwork, either in the ceiling void, under the floor, or sometimes both.  This will be dependent upon your pool design and available space.

10) Pool Filtration and Water Management Systems

State of the art filtration systems, pumps and dosing systems are installed to ensure you swim in crystal clear water.

We will complete your luxury pool project by filling the swimming pool with our drinking water quality pool water.  Starpool use Dryden Aqua integrated water systems to remove toxic chlorine by-products and ensure that your pool water is consistently clean.

Starpool is the UK’s largest approved installers of the award-winning Daisy Water Filtration system, which incorporates the world’s best pool water filtration media, AFM.

Once the plant and equipment are fully installed and the pool shell is complete, we can start to look at the commissioning stage.
