Natural swimming pools vs traditional pools each offer something different to your garden. Visually they are quite a stark contrast, with natural pools tending to blend more into their environment and become part of the ecosystem, with areas of planting and a "regeneration zone".
Chlorine pools appear more sleek and man-made, relying on hard landscaping materials to fit with them. They also need more "kit" in the form of filters, pumps and heaters, which don't need to be factored in when designing a natural pool.
Ultimately they both offer the same thing, a beautiful garden feature for swimming and bathing, but aesthetically and functionally they vary greatly. Which actually helps when deciding which swimming pool is right for your garden.
Natural swimming pools vs traditional pools
There will always be costs and maintenance associated with all swimming pool types, but if you are set on a swimming pool for your back garden then there is always a way to make it work for you.
"The water in a natural swimming pool is filtered by the plants and micro-organisms in the water while a traditional pool is filtered and cleaned by chemicals and a mechanical filtration system. Natural pools have a greater variety of designs and can be customised to almost any shape, size and aesthetic," says Thomas Goodman, construction expert at My Job Quote.
"Traditional pools generally have an obvious man-made look," says Thomas, though there are pool landscaping ideas which can make them appear more muted. "Running costs for a natural pool will be lower than a traditional pool as most of the cleaning of the water is done naturally although pumps and filters can be added," says Thomas.

Natural swimming pools: Pros and cons
"You can go for a natural swimming pond, which remains uncovered all year because natural pools are not heated, which saves the cost of the cover and heating, and allows your pool to double up as an ornamental body of water," says landscaping designer Marlene Lento.
"Part of this set-up are regeneration zones planted with plants that purify the water. These zones are shallow and heat as water circulates through them, the pool heats up to a comfortable temperature quickly in summer," adds Marlene.

Thomas Goodman outlines the pros and cons of natural pools below including swimming pool costs, maintenance, aesthetics and durability:
Chemical-free: a natural swimming pool uses no chemicals so is more environmentally friendly.
Natural aesthetic: natural pool landscaping is easy as they can be almost any shape and blend well into a garden. Some may feel that the natural environment means a more enhanced relaxation.
Costs: you don't need to heat a swimming pool if it's natural sothere are no heating costs attached to natural pools which contribute to their low running costs.
Longevity: if installed by a qualified professional they will last many decades with yearly maintenance.

Cons of a natural swimming pool:
Lack of heat: natural pools cannot be heated. However their regeneration areas are designed to warm the water naturally in summer.
Essential plant life: though some people may see the lush plant life around their pool as a benefit, the plants that are needed for filtration require regular maintenance. The area of the pool with the plants cannot be used for swimming.
Water testing: more frequent water testing may be needed to control buildup of algae.
Traditional pools: Pros and cons
Those looking for a clean and contemporary aesthetic will likely prefer the style of traditional pools. If you have limited space this is probably your best option too as you don't have to account for the plants and regeneration zone.
Garden designer Fi Boyle suggests if you already have a traditional pool you can look at converting it to a non-chemical pool. "There are some great companies out there that do this such as Water Artisans. It will need a regeneration zone and so this in turn will make the whole space much more interesting," says Fi.

Pros of traditional swimming pools:
Chemical filtration: Most cleaning and filtration is done automatically by the filtration system and the water will be bacteria-free and crystal-clear thanks to filtration and chlorine.
Heated: Unlike natural swimming pools, water can be heated to your own specifcations.
Size: how much space you need for a swimming pool is different for natural swimming pools vs traditional pools. There is no need for a filtration zone therefore all of the pool area can be used for swimming. There is a range of sizes and designs to choose from.

Cons of traditional swimming pools:
Cost: traditional pools tend to be more expensive to build, run and maintain than natural pools. Heat pumps for swimming pools are seen as the most economical way to heat a pool but still has costs associated.
Environment: as well as chemicals and filtration systems required, energy is needed to heat a traditional pool.
Stands out in a landscape: Traditional pools tend not to blend into the natural surroundings and are mostly rectangular in shape, any other shapes will be more expensive.
Covers: though some may see the ability to cover your pool as a benefit, it's not necessary to have them for natural pools, whereas they are essential for traditional pools when they're not in use
FAQs
Do you need planning for a natural swimming pool?
As natural swimming pools require no building structures or heating system installation they do not usually require planning permission. However, your local authority may have limits on the size of pools allowed for your space and where they are positioned in relation to your house.
"As with any large building project it’s advisable to consult your local authority about any swimming pool planning permission and building regs that you may need to adhere to. Most people don’t need planning permission as a pool is considered a garden project and usually falls within permitted development rights. However, if you live in an Area of Outstanding Natural Beauty, in one of the National Parks or the Broads you will need planning permission," says construction expert at My Job Quote Thomas Goodman.
So it's always worth checking on your local council website to avoid any potential issues.
