Each kit comes with everything necessary to build a complete functioning pool, except the concrete for the base, electrics and of course the water to fill it with! This new version includes the following upgrades:- a 2-piece thicker top rail complete with hidden fixings kit; under-bracing making the pool suitable for siting on a flat and stable lawn; a smoother finish to the external side timbers. The pool shell walls are manufactured from Scandinavian Redwood, pressure treated with an ecologically safe preservative and carry a ten year manufacturers warranty. The 2-piece top shelf is made from timber including a hidden fixings kit which hides the screws by fixing to the underside of each plank rather than through the top. Please note; if opting for the Solar Heating Kit, this pool will require seven panels for optimum effect. The liners are manufactured by Plastica from 0.75mm vinyl in a plain blue with a mosaic tile band, and carry a standard five year warranty. Support braces must be used when the stretched octagonal pool is built above ground, and preferably when built in-ground, although if the pool is properly excavated and back-filled with the correct grade of pea shingle this may not be necessary. Steel Under Braces are supplied for bedding in to concrete or can be installed in the lawn. This pool is also particularly suited for in-ground pools.
