ADVANTAGES: Lower Chlorine Levels: Saltwater pools utilise a salt chlorinator or salt cell to generate chlorine, but the chlorine level is typically lower than in traditional chlorine pools. This results in softer water that is often gentler on the skin and eyes, providing a more comfortable swimming experience. Reduced Maintenance: With a saltwater pool, there's no need to add chlorine regularly, as the salt cell produces chlorine as needed. This can lead to fewer fluctuations in chlorine levels, simplifying pool maintenance and reducing the need for frequent chemical adjustments. Cost-Effectiveness: Despite higher upfront costs for installation, saltwater pools can be more cost-effective in the long run. You'll save money over time as there's no need to continuously purchase, transport, or store chlorine, resulting in lower ongoing maintenance expenses. Minimal Chemical Usage: Saltwater pools generally require fewer additional chemicals such as algaecides or shock treatments, contributing to a more environmentally friendly and sustainable pool environment. DISADVANTAGES: Higher Initial Cost: The installation of a saltwater system can be more expensive compared to traditional chlorine systems due to the need for a salt chlorinator or salt cell. Increased Electrical Consumption: Salt cells require electricity to convert salt into chlorine, leading to additional electrical costs over time. Salt Corrosion: The presence of salt in the pool water can cause corrosion on certain pool fixtures, equipment, or types of stone decking, potentially requiring costly repairs or replacements. Complexity: Maintaining optimal salt levels and ensuring the proper functioning of the salt cell can be challenging. If the salt cell malfunctions or if salt levels are not adequately maintained, there may be insufficient chlorine production, leading to potential pool problems such as algae growth or water quality issues. Regular monitoring and maintenance are essential to address these challenges and ensure the effective operation of a saltwater pool.

ADVANTAGES: Lower Initial Cost: Traditional chlorine pools generally have a lower upfront cost compared to saltwater systems, making them more budget-friendly for initial setup. Simplicity: Many pool professionals and owners are more familiar with maintaining chlorine pools, as they have been the standard for many years. This familiarity can make troubleshooting and maintenance tasks more straightforward. Fast-Acting: Chlorine has the ability to act quickly to resolve water problems, such as algae growth or bacterial contamination, providing rapid and effective water treatment. DISADVANTAGES: Regular Maintenance: Chlorine levels in traditional pools need to be checked and adjusted more frequently to maintain optimal water quality. This requires regular testing and chemical additions, increasing the ongoing maintenance workload. Cost of Chlorine: Over the lifespan of the pool, continual purchases of chlorine are necessary to maintain appropriate chlorine levels. The cost of chlorine can accumulate over time, contributing to higher long-term maintenance expenses. Potential for Irritation: Higher chlorine levels in traditional pools can cause skin, eye, and hair irritation for some individuals, especially those with sensitive skin or allergies. This can result in discomfort or allergic reactions for swimmers. Odour and Taste: Chlorine pools can sometimes have a distinctive smell and taste, which some people may find unpleasant or off-putting. This odour and taste can be particularly noticeable in indoor pools or pools with inadequate ventilation.

ADVANTAGES: Chemical-Free Swimming Experience: Natural pools use biological filters and aquatic plants to keep the water clean, eliminating the need for chlorine or salt. This provides a more eco-friendly and chemical-free swimming experience, which can be beneficial for individuals with sensitivities or allergies to pool chemicals. Blends Seamlessly with Environment: Natural pools blend harmoniously with their surroundings, resembling natural bodies of water like ponds or lakes. They enhance the aesthetic appeal of outdoor spaces and create a tranquil and inviting atmosphere for swimmers and spectators alike. Low Maintenance: Once established, natural pools typically require lower maintenance compared to traditional chlorine or saltwater pools. The self-regulating ecosystem helps to maintain water quality naturally, reducing the need for frequent chemical adjustments and cleaning. DISADVANTAGES: Initial Cost: The initial installation cost of a natural pool can be higher than that of traditional saltwater or chlorine pools. Building a natural pool requires specialized construction techniques and materials to create the ecosystem, which can increase upfront expenses. Limited Temperature Control: Natural pools rely on natural processes for temperature regulation, which may result in cooler water temperatures compared to heated saltwater or chlorine pools. Swimmers who prefer warmer water may find natural pools less comfortable, especially in colder climates or during cooler seasons. Potential for Algae Growth: Without chemical treatments like chlorine or salt, natural pools may be more prone to algae growth under certain conditions. Maintaining the balance of the ecosystem and water chemistry is essential to prevent algae blooms and maintain water clarity. Complex Design and Maintenance: Designing and maintaining a natural pool requires specialised knowledge and expertise in aquatic ecology and landscaping. Proper planning and ongoing management are necessary to ensure the health and stability of the ecosystem, which may involve periodic adjustments and interventions to address issues such as algae growth or water clarity.

 Trustindex verifies that the original source of the review is Google. This process has been so easy from start to finish. To begin with, we wanted to see the pool we had chosen in situ. This was arranged very quickly, and it was exactly what we were looking for. Ordering was also straightforward, and everything from that point through to delivery went exactly as expected. Once the pool was installed, we spent a few hours going through all the maintenance requirements (despite being in the middle of a building site). It was very thorough, and I’d highly recommend anyone doing this to take videos we’ve found them to be a real lifesaver. When we struggled on our own, Penny was fantastic even messaging me back on a Sunday when I was completely floundering. Now it’s all done, we feel confident about what we need to do and we absolutely love our pool. We just need the rest of the house finished before we can start swimming, but it’s there ready and waiting, along with the bottle of champagne they kindly left us as a gift. Thank you both so much we love it. Claire and Andy x

 Trustindex verifies that the original source of the review is Google. I cannot recommend Waterstream highly enough. Mike was a pleasure to work with, from initial scoping despite all our questions being pool novices, through to a very clear handover, always responsive and helpful. Billy and the installation team were total pros, always working hard, in good spirits, kept to the expected timeline, keeping us updated on all the progress, and maintaining the site in good order. Simon’s sign off was meticulous, the attention to detail by all involved having been of the highest standard. The resulting pool (Aqua Nova 84, with a turbine which is fantastic), is first-class and will be enjoyed by family and friends for many years to come. Thanks to the entire team!

 Trustindex verifies that the original source of the review is Google. We had a pool installed by Compass Pools earlier this year. It was a fantastic experience from start to finish. From Nick talking me through the options and answering my multiple dumb questions, Billy, Mark and Kyle that did our installation over the wettest winter in memory and then Ryan who talked me through resetting the cover open and close mechanism when it got stuck after a power cut. A really professional team and more importantly a brilliant product. Thanks guys!

 Trustindex verifies that the original source of the review is Google. Yesterday our Compass pool was officially handed over to us & we couldn't be happier. Tracy has been phenomenal throughout the whole process, answering all of our many questions & reassuring us - it's a huge decision to make! The biggest concern we had was getting the pool off our lane, down the drive and over the house.  Elliot had this well under control. The delivery drivers & the crane operator were unbelievable and even the neighbours enjoyed watching the process. Thank you to all at Compass, especially Tracy.

Salt Water Pool Design

Salt water swimming pools are increasingly growing in popularity since they use less chlorine and require less sanitation work than traditional pool-based designs. As a lower maintenance pool, they’re a great way to save money on maintenance while still enjoying the benefits of an outdoor pool on your own property.

Each one of our Compass Pools can be installed as a saltwater pool – all our designs can be fitted with an IntelliChlor chlorine generator. This system uses regular table salt to produce chlorine in the swimming pool, which regulates the amount of chlorine contained within the pool. It also continually recycles the water to ensure it stays safe and hygienic for you to swim in.

Compass swimming pools are the ideal choice for saltwater as they are made using a specialist ceramic composite material. As a result, they won’t corrode from salt in the same way that concrete pools do, ensuring your pool lasts for many years to come.

We offer a wide variety of unique pool designs, with over 30 different shapes and sizes and a host of customisation options, so you can create your dream pool that will exceed your expectations. What’s more, we bring decades’ worth of experience and expertise to every one of our pool builds.

Why Choose a Salt Water Swimming Pool?

Saltwater pools offer a number of advantages over traditional freshwater pools. While saltwater pools still contain some chlorine, the concentration is significantly lower, resulting in a gentler and less drying experience for your skin and eyes. In fact, many people believe that saltwater can be beneficial for the skin, providing a natural exfoliation while remaining gentle. The water in a saltwater pool has a silky, luxurious feel and won’t cause eye irritation or hair discoloration.

Benefits of Salt Water Pools:

Lower chlorine levels for a more comfortable swimming experience
Silky, gentle water that’s easier on the skin and eyes
Natural exfoliation properties for healthier skin
No harsh chemical Odours or discoloration of hair

Freshwater pools require constant monitoring and adjustment of chlorine levels, while salt water pools are self-regulating thanks to their built-in chlorine generator. This means less time spent on maintenance, allowing you to simply enjoy your pool. A saltwater pool system also offers lower annual operating costs, as you don’t need to continuously purchase and add chlorine and other chemicals.

At Compass Pools, our saltwater pools are constructed using high-quality materials that are ideally suited for saltwater environments. Our one-piece ceramic pools are resistant to corrosion from saltwater, ensuring a long-lasting investment. Additionally, we upgrade our stainless-steel fittings to marine-grade 316 stainless steel at no extra cost, providing even more durability and longevity for your saltwater swimming pool.

Frequently Asked Questions

How do saltwater pools work?

While freshwater pools rely on chlorine to disinfect the water and keep it free from algae, bacteria and other organisms that can be damaging to our health, saltwater pools use an electrolytic chlorine generator or ECG. This generator separates salt in the pool water into two primary elements, one of which is chlorine. This is then circulated around the pool to sanitise it.

The main advantage of this process is that it doesn’t produce chloramines which is an irritating by-product of store-bought chlorine. These chloramines are what give the water in swimming pools that distinctive chlorine smell and can sting your eyes.

What kind of salt is used in a salt chlorine generator?

There are several options for the salt used in a saltwater pool:

• Solar salt
• Mechanically evaporated salt
• Mined salt

You should only use salt that’s intended for swimming pools, food-grade and non-iodised. The higher the purity level of the salt, the less maintenance will be required for your pool. It’s recommended to choose a salt that’s 99% purity or higher for the best results. It’s not recommended that you use rock salt or calcium chloride – rock salt won’t dissolve enough and isn’t of a pure enough quality, while calcium chloride impacts the hardness of the water and can lead to deposits forming on the pool walls.

How much salt does a saltwater pool need?

Salt levels in pools are typically 2,700-3,400ppm but it depends on your cell’s rating, as generators have different ranges. The optimal concentration is around 3,200ppm. PPM stands for Parts Per Million and it’s the amount of salt in milligrams that’s present in one litre of water. So, depending on the size of your pool and how much water it holds, the concentration of salt will vary.

However, there are online calculators you can use to determine how much salt is required for your pool. You can also check the reading on your salt chlorine generator to make sure it’s at the right level, or use a salt testing kit for an accurate measurement.

How long will a salt chlorine generator last?

Salt chlorine generator cells will usually last between 3 and 7 years. However, maintenance and salt levels will impact this. Maintaining your salt generator regularly will help it to last longer and improve the quality of the water in your swimming pool.

Can I still use an automatic cover with a saltwater pool?

There are a lot of metal components with an automatic cover, which saltwater can rust and damage, so we recommend using an inline erosion feeder if you have an automatic cover.

Jane Styslinger – Hampshire
"We couldn't be happier with the service we received from all the team. Right from Sheila in sales on day 1 through to John and Glenn on site. Now we have a pool the boys are in it in all weather and it gets them off the Xbox! They have used the pool every day since May-be it after school or early in the morning and we both use it to exercise whenever we have a spare half an hour.That alone makes it more than worth it."

"Compass were a dream to deal with. They visited and prepared a very detailed quote with full details/breakdown. A start date was agreed on, they turned up on the agreed day and finished the install ahead of schedule. The install team were a pleasure to work with and had a good eye for detail / getting things right / keeping the site tidy. I would not hesitate to recommend Compass."
