Complex structural engineering
Balance tanks and additional pumps

Endless pools are compact swimming pools with an adjustable current system that allows you to swim continuously in place. They are generally more affordable because:

Swimming pool installation hourly rates
Due to the nature of installing a swimming pool, a number of different tradespeople will usually be needed. Therefore, there is no single hourly rate for swimming pool installation. However, here are the average rates of the
various specialists you might need to hire for the job:
Electrician cost– £50per hour
Plumber cost– £50per hour
Handyperson cost– £30per hour
Types of swimming pool
When deciding on an indoor or outdoor pool, you can choose from two types:
Pre-built resin or fibre pools
Poured or sprayed concrete pools
Pre-built resin or fibre pools
Pre-built pools are already constructed from materials such as fibreglass. The swimming pool is placed, fully built, into a pre-dug hole. The benefits are that the pool is already constructed and water-tight. However, they only come in a limited range of standard shapes and sizes.
Pre-built resin and fibre pools are m
ore flexible than concrete pools, which makes them more resistant to cracking. Average swimming pool installation costs are lower too.
Poured or sprayed concrete pools
Poured concrete pools are built by shuttering and pouring ready-mixed concrete to form a shell. Sprayed concrete pools use pressure sprayers to shoot concrete at high pressure at high speed onto the reinforcing steels.
The concrete is then sealed and finished with a layer of tiles. Poured or sprayed concrete pools can be built in all shapes and sizes, but they are more expensive to construct than pre-built resin and fibre pools.
Steps to build a swimming pool
Building a swimming pool is a complex process that typically follows the steps below:
Excavation - digging out space for the swimming pool
Installing a pre-built pool or concrete shell
Tanking - the process of creating a watertight shell
Installation of the swimming pool liner or tiles
Fitting of the filtration system to keep the water clean
Installation of the heating system, fittings and pipework

Can I build a swimming pool myself?
Building a swimming pool is not a DIY job and could be dangerous if not done properly. Only work with an established and experienced professional.
Before going ahead you should speak to an experienced swimming pool builder who can assess your property and your proposed pool location. They can answer any questions you may have about the design and installation of your pool.
