It’s not every day you decide to dig a hole in your back garden and install a swimming pool, but it may be easier than you think!

Professional DIY Pool Kits

Understandably, most people’s concept of a swimming pool is a fully tiled concrete pool, when they get a price they would think “horrific cost”. They would be right! An average cost of a concrete pool starts from £50,000.00 for 30′ x 15′ pool size and takes on average 8-10 weeks to build.

One of the great advantages of installing a liner type pool construction is that in approximately 7-10 years, the liner will have to be replaced. This is a very simple and straight forward procedure and at a present-day costs, a replacement liner for a 30 x 15′ pool would cost £2150 inc. VAT. Remember, the liner is the finished cosmetic look of the pool, so every 7-10 years it will look like a brand new installation!

It is also possible to raise the pool above ground level by as much as 18″ using the soil to build a patio around it, finished with either a retaining wall or gradually sloping turf. This may be done to save on the cost of earth removal and the time and effort involved in excavation, especially when hand digging is involved.
