An existing pool liner will last anything from 7 years to in some cases 20 years depending on the quality and how they have been looked after.
There are a range of colours & patterned styles available, and the option of a patterned tile band.
You can choose a liner that will be suitable for a pool water temperature of up to 35°C or a standard liner to 28°C.
The liners I fit are guaranteed for either 10 or 12 years depending on the specification.
The colour of the liner fabric does not translate the water colour realised when it is installed and the pool full.
Here follow the some of the selection of liners available, and friezes (tile bands).
There are other colour effects available, please contact me for further information.
