Why choose an indoor swimming pool over an outdoor pool?

Whether you want to upgrade your exercise regime, need a place to relax in utmost luxury or you want to add a further dimension to your property, an indoor pool can make a wonderful addition that provides great value to any home. The convenience and luxury of having a pool at your disposal at any time, day or night, whatever the season, is one well worth investing in.

Choosing an indoor pool build over an outdoor swimming pool means you can use it whatever the weather, so you no longer need to neglect your time in the pool during the colder seasons. Indoor swimming pools are cheaper to operate and easier to maintain compared to an outdoor pool, as there’s less heat loss thanks to the contained atmosphere. Our professional pool builders are on hand to help you make the right choice for your property.

Installation into an existing building

If you are looking to install an indoor pool inside an existing building, be aware that this is usually a more expensive option than constructing a new building for your pool. The main reason for this is that your current building will likely need to be underpinned if your pool is going to be positioned within 2m of external or supporting walls. We also install our pool as a whole shell, meaning that we would require access the size of the pool’s cross profile (normally about 4m x 1.8m), although this may not be a problem if you are installing sliding doors at the same time. You will need to work with an external contractor in this instance to provide us with a ready excavated hole and access to get the shell in.

Installation into a new building (built by contractor)

If you are going to construct a new building for the pool, your pool is typically installed first and its housing is built around it. The process normally goes as follows;

  1. Contractor excavates for foundations of building
  2. Contractor pours foundations
  3. Contractor or Compass excavate the pool (to specification)
  4. Compass install pool shell and pipework, fill with water
  5. Compass board over the pool
  6. Contractor constructs building, without decorative finishes but including power
  7. Compass return to fit plant room and coping stones
  8. Compass works with trusted trusted ventilation contractors to install duct work for air control systems and pool heating
  9. Contractor returns to install plasterboard, finishes and flooring

Features of your indoor pool design

When creating your perfect indoor pool, there’s the option to customise the design so it perfectly meets your needs.

In-water seating and spa features can help you create a luxurious indoor swimming pool installation that’s truly unique to your property.

Indoor pool construction

Whatever style of indoor pool design you’re considering for your property, having the right team of experienced indoor pool builders on your side is essential. Indoor pools are constructed and installed in a similar way to an outdoor pool, but where an outdoor pool deck is sloped away from the pool to keep debris out of the water, an indoor pool deck slopes away from the walls. A broader range of materials can be used for indoor pool installations, as there’s no risk of the water freezing and thawing which needs to be considered with an outdoor pool. An indoor pool room looks aesthetically the same as the rest of your property, but the engineering differs to maintain the appropriate heating and humidity levels.

The air quality in your indoor pool room needs to be well-maintained, either via exchanging humid air for fresh air or using a dehumidification system. This needs to be well designed to make sure that the air isn’t forced across the surface of the pool which can speed up evaporation and condensation. Our experienced team of indoor pool builders will work with you to create a dehumidification system that is appropriate for the size of your swimming pool and reduces evaporation correctly. We also recommend that a pool cover is incorporated into your indoor pool design, which can reduce humidity and evaporation considerably.

We know that maintaining your property is incredibly important to you and we take great care to ensure that the design of your indoor swimming pool exceeds your expectations and is nothing less than perfect. At Compass Pools, we strongly believe that clear communication should be central to the entire process of an indoor pool build and it’s the cornerstone of the excellent customer service we’re renowned for. We’ll ensure that throughout the entire design and construction process, we’ll stay in close contact with you and other parties involved in the build.

Structure and design

Part of the indoor pool build involves making sure that vapour barriers are installed behind the walls to prevent moisture from reaching the structural framing of the property. An indoor pool requires proper deck drainage to prevent puddling which can exacerbate humidity levels and can impact the look of your swimming pool – a low-profile drain keeps the perimeter of the pool looking neater and tidier, while also serving a practical purpose. You may also choose a floor heating system which can help to reduce water around the pool and makes stepping out of the pool more comfortable during the winter months.

    There are two options when installing a sliding dome cover; either a full-height dome or a low-profile dome. Either option will help you reduce you running costs, and let you to enjoy your pool all year round; keeping the water temperature contained in winter, and allowing you to simply slide back the cover to swim outdoors in warmer months.

Frequently Asked Questions

What chemicals does my pool need?

Pools can be kept clean with a variety of different chemicals. Our specialists will be able to provide you with advice on the chemicals that we recommend depending on the circumstances of your swimming pool.

How long does construction take?

This can vary on a huge range of factors, including the work that you need to do on your property itself to prepare for the installation. The actual construction of the physical pool takes very little time as our one-piece pools are simply craned into a previously excavated hole, rather than having to go through the lengthy process of adding concrete and tiles.

What protection can I put in place for children?

It is important to put protections in place for children against falling into pools, both indoor and outdoor. Pool covers can be used indoors, although it is important to remember that no cover guarantees safety. It is also sensible to make the entrance to your indoor pool lockable so that young children cannot wander in unsupervised.

How much does an indoor pool cost?

The first thing to note about having an indoor pool built is that it will typically be more expensive than an outdoor pool. This is naturally the case because you are effectively having to build a pool at the same time as building an extension to your house (or having serious remodelling work done on the property).

The final price can vary enormously, although we have created a useful guide to illustrate the kind of costs that would be involved. However, it varies on factors such as the size of the pool and how it is built.

What are the average running costs of an indoor pool?

The Swimming Pool and Allied Trades Association (SPATA) estimates that energy and chemical costs per day combined to around £7.50. Once again, however, this will depend enormously on the size of the pool, how much you use it, the temperature that you want it to be, and the season of the year.

There are ways that you can mitigate the running costs of your pool. For example, during the installation phase of the pool, you might wish to have a solar heating system installed to reduce the amount of energy you use to heat your pool.

Do you need planning permission?

In the majority of cases the answer to this question is ‘no’, as long as the building that you are going to house the pool within is freestanding. Since October 2008 outbuildings have been considered to be Permitted Development, and do not require planning permission (within specific terms and conditions).

However, in all cases whether you are having an extension built for your property or creating an outbuilding to house your pool, we would recommend speaking to your local council to establish whether you need to apply for specific permission.

What sort of access is required for installation?

Once again, this relates to the specifics of the pool and where it going to be housed.

Can you heat an indoor pool?

Yes! Just as with an outdoor pool you can have an indoor pool heated to a temperature of your choosing. This is easy to setup during your installation and you can choose from a range of different options from a standard oil or gas heat pump to direct solar heating. Talk through the process with a member of our team and we can help you with details on which kind might be perfect for your home.

What are the advantages of an indoor pool over an outdoor pool?

There are many advantages of indoor pools. Firstly, unlike outdoor pools, indoor pools can be used all year round, and in any weather. They are typically also easier to heat and easier to keep clean than outdoor pools.

Can home pools get algae?

In traditional home swimming pools it is possible for algae to grow and this includes both outdoor and indoor constructions. However, Compass Pools have a number of features that help to prevent the growth of algae. Compass Pools are created in one piece using ceramic composite which is impermeable to bacteria. If you are concerned about getting algae in your pool, please speak to us about having a one-piece ceramic pool installed.

What size pool do I need?

The size of your indoor pool is completely down to you. It can depend on a large range of factors including the amount of space you have to work with as well as your budget. Remember that you do not necessarily need to have a built pool constructed. For many homeowners, a simple plunge pool is all that they are really looking for, and this gets as much use as a larger pool would.

What size pools are available?

At Compass Pools, our ceramic composite pools are prefabricated to order and are available in a range of styles and sizes. You needn’t worry about having a limited choice – we have 9 different models available in 27 sizes, including plunge pools and lap pools. We also offer a large selection of options to customise your swimming pool, including a range of features such as down lighting, waterfalls, deck jets and more.

Can I customise my pool?

Yes, we offer a large variety of pool customisation options including a selection of colours as well as features such as an down lighting, waterfalls and much more.

How can I make the most of my space?

The size and shape of your swimming pool can be selected to fit the dimensions of the space you are working with. If you are interested in swimming laps but are limited on space, there are options available utilising water jets. These allow you to swim against a constant current, so you can enjoy lengthy swimming sessions even in a relatively small pool.

Who do you need to work with to have an indoor pool installed?

To complete a successful indoor pool project, it is important to work with a swimming pool designer, an interior designer and an architect. Having professional expertise in all of these areas helps to ensure that your installation runs smoothly.

Is it easy to keep a pool clean?

Yes, Compass Pools are especially easy to clean as they are a smooth, continuous surface, unlike a tiled pool. Additionally, the ceramic composite is impermeable and therefore toxins and dirt cannot enter the water through osmosis.

How much maintenance needs to be carried out?

Indoor pools typically require less maintenance than outdoor pools. This is in part due to the fact that there is less detritus that can get into the pool indoors. Most pools require only a few minutes of chemical maintenance each week, checking over the water to ensure that the levels of chemical is correct.
