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.

A pool with a view

Infinity pools offer what some consider to be the ultimate in luxury; a pool with the appearance of no boundary that seems to disappear into the surrounding landscape. Infinity pools are perfect if you’re looking for a show-stopping pool design that’s lower maintenance than other outdoor pools and works well in outdoor spaces with a natural slope.

How do infinity pools work?

An infinity pool gets its name for the seamless blend between the edge of the pool and its surroundings – usually another body of water, such as a sea or lake. With a regular pool, the water is contained by higher pool walls, but an infinity pool works like a waterfall, with lower pool walls to match the water level. This creates the illusion that the water is, as the name suggests, infinite.

The lowered wall is gradually sloped to allow the water to flow out into a catch basin which is built along the bottom of the exterior lowered wall. This collects the water and pumps it back into the main pool or recirculates the overflow, so the water level remains consistent.

For this reason, a true infinity pool – also known as a negative edge pool – must be built on sloped ground, to make it look like the pool is completely edgeless. In order to achieve this illusion though, the water level needs to flow over the edge of the pool into a weir or secondary pool.

What are the benefits of Infinity Pools?

The aesthetic of an infinity pool is one of the primary reasons why they’re chosen – they have an eye-catching design that creates continuity with the surrounding landscape. If you want a space to relax where you’ll feel secluded and nestled in nature, an infinity pool is a great option that sits seamlessly among the greenery.

Since infinity pools spill over into the lower edge of the structure, they create a waterfall effect which provides the natural sound of rushing water. This makes an effective natural noise barrier from the surrounding sounds of your property, from traffic and people walking past to neighbours.

Infinity pools can also be considered a more environmentally-friendly option – although they require more powerful pumps than a standard pool, they tend to only operate when the pool is in use. And since the lower pool collects the water, it can be recycled back into the main pool.

 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. 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.

A stunning design that’s easy to maintain

Infinity swimming pools can be truly stunning. At Compass Pools, we understand how to make use of the surroundings to maximise the look of the pool.

The location of your infinity pool is extremely important. Surrounding levels must be carefully measured to determine how to achieve the pool’s infinite-edge look then, once the relevant sight lines have been determined, you need to think about which materials to use. To achieve the maximum effect, the materials you choose should closely match the body of water, sky or landscape that the pool will need to blend into.

Maintenance is also easy with an infinity pool. If clearing dead leaves and insects from your swimming pool doesn’t really appeal to you, one of Compass Pools’ innovative overflow and infinity deck swimming pool designs ensures this won’t be a problem to be concerned about.

In addition to the materials, think about the view you’ll gain from your pool. Part of the joy of having a pool on your property is being able to relax and enjoy your surroundings, and that’s amplified when you choose an infinity pool where the aesthetic of the design plays such a central role.

Most infinity pools are constructed in elevated locations so you can overlook the view, but for residential infinity pools, this isn’t always possible. In such instances, you should choose a location that is surrounded by a beautiful view or inviting surroundings.

When considering locations for your pool, you should be checking for sufficient slope as it’s easier to construct this style of pool if the ground has a gentle slope. If your garden is uneven and slopes, an infinity pool can be a great alternative to a traditional garden swimming pool. However, if your garden is flat, it is possible to create an artificial slope to construct a fully or partially raised infinity pool.

Another benefit of choosing an infinity pool is that they are low maintenance. If clearing dead leaves and insects from your swimming pool doesn’t really appeal to you, one of Compass Pools’ innovative overflow and infinity deck swimming pool designs ensures this won’t be a problem to be concerned about.

How we install your luxury infinity edge swimming pool

Compass swimming pools are unibody lightweight structures, made of carbon ceramic and installed in one-piece by crane. Our lightweight swimming pool construction material overcomes many of the structural issues involved with building a concrete infinity pool, which you can find out more about here.

Our one-piece shell design makes the installation extremely accurate and quick to install. Once the pool has been lowered into a previously excavated hole, we maintain its water level using VSD (variable speed pumps) and a computer-controlled water level system. This not only ensures you achieve the correct water level, but it will also save you money on running costs.

Maintenance tips for infinity pools

Whichever style of swimming pool you choose, maintenance will be required to keep it hygienic and usable for a long time. Luckily, infinity pools are an easy design to maintain – here are a few tips to keep your pool clean and working properly.

Clean the catch basin to prevent build-up of leaves and debris
Keep the drain clear to allow the water to flow freely
Some water will naturally evaporate so top up the water every so often to keep it flowing at the right level
Check the chlorine and pH level regularly to ensure they stay in the normal range
Always check the performance of the pump and if you spot any unfamiliar noises, have it serviced

Are infinity pools safe?

Yes, infinity pools are safe since you’ll be swimming up against a wall when you reach the edge of the pool. While the pool appears to disappear into nothing, there is a secure edge that keeps you and other users of the pool completely safe.

Are infinity pools challenging to install?

Installing an infinity swimming pool is more technically complex than fitting a standard pool for two key reasons:

Engineering logistics: installing a pool on a hillside or slope not only poses more logistical issues, but it also complicates the engineering work required. For example, overflow edges will need to have a wall structure built, rather than rely on the surrounding ground to support them.

Careful calculations: the pool’s edges will need to be carefully calculated and constructed to the same tolerances of a deck level pool (approximately 1-2mm along their length). To do this though, the design team will need to determine how to construct a complex system of balance tanks and pumps, ensuring the overflow remains constant regardless of how many people are in the water.

How much does an infinity pool cost to install?

Naturally, beautiful things are never cheap and unfortunately the same principle applies to infinity pools. Due to the complex design involved, installation needs to be completed by a qualified builder – you definitely do not want a self-builder or first-time contractor to complete the work.

Infinity pools cost approximately £30,000 more than similar-sized conventional free board or skimmer pools. However, this calculation very much depends on the site conditions and available access.

How much does an infinity edge pool cost to run?

Infinity pools naturally cost more to run than conventional freeboard pools. This is mainly due to the cooling effect on water that flows over the pool edge – an effect which is greatest when the outside ambient temperature is low.

This cooling effect can be eliminated through Compass Pools’ variable water level system (VWLS), which reduces water usage when the pool is not in use. Without this system, additional running costs will be need to both heat the water and run the overflow system. It is difficult to determine what the exact cost will be, as it really depends on a number of factors. Some of these factors include:

Air temperature.
Wind speed.
Site exposure.
Soil type and water content.
Pool temperature.
Hours of pool use.

Full Infinity Deck Level Pools

For the ultimate in opulence, Compass Pools can provide you with a deck level swimming pool where the water flows in all four directions simultaneously. Or, if your swimming pool is installed on the side of a slope, you can enjoy a magnificent infinity effect swimming pool whereby the water flows over one edge, exactly as you might see in a luxury hotel resort.

All Compass Pools infinity and overflow swimming pool systems are manufactured from high grade 301 stainless steel. This ensures corrosion is not a problem during the normal lifetime of the pool and you can enjoy years of hassle free service. For salt water swimming pool applications, there is also a 316L stainless steel option available for extra protection against the corrosive effects of salt water.
