Wondering about building an indoor pool?
As a leading indoor swimming pool contractor, Starpool are experienced with every luxury pool construction method on the market.
From our experience, we highly recommend concrete pool shells for indoor swimming pools. That is because the benefits of sprayed concrete swimming pool shells outweigh all other options.
How Long Does It Take To Build An Indoor Swimming Pool?
Typical timeframes for building a pool shell, waterproofing, curing and installation services usually range between 12-16 weeks. This estimate does not include the commissioning stage.
How To Build A Swimming Pool Step By Step
Here we explain the step-by-step we take in the indoor swimming pool building process, according to the pool’s design specification:
1. Constructing The Swimming 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 the 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 indoor 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.
From start to completion, the construction of your pool shell will take between 2 and 5 weeks, depending on the dimensions and complexity of your swimming 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.
5. Waterproof Coating
The next phase of the indoor 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.
- 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. Pool 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.
Then we will 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. Pool 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 are regulated in your indoor pool space. That 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 the 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 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.
We are 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.
