Water Features

If space is limited or exercise is a priority, resistance jets provide a continuous current for an endless swim. Stress relieving massage jets, calming ambient waterfalls or soothing bubble loungers are just a few of the additional water features available to compliment your below ground pool and spa.

Plunge Pools

Plunge pools are typically filled with cold water and used for rapid cooling after exposure to extreme dry or humid heat in a sauna or steam room.

Lighting

Choosing the lighting for your subterranean oasis is just as important as the design itself as lighting impacts the mood and feel of your pool and spa. Your preference could be a calming, warm glow or energising, vibrant colours that change hues taking you on a sensory journey through the spectrum.

Moving Floor Swimming Pools

Where space is a premium, or you may require alternative usage of the space from time to time, a moving floor pool is the perfect choice for your underground pool. Not only does this option enable you to decide between a swimming pool or hard floor usable floor space, it also allows for various depth’s to suite different ages, abilities and needs, creating a safe and adaptable environment.

Frequently asked questions

Do I need planning permission for a basement swimming pool?

Planning permission may be required if your property is a listed building, in an Area of Outstanding Natural Beauty (AONB), or if you’ve given up permitted development rights. Indoor pools may also require permission based on building regulations and project scope. Consult your local planning authority for specific advice.

What are the benefits with basement pools?

There are many benefits of transforming your basement into an underground swimming pool, some of which include all year round use, a luxurious escape from the outside world, utilising your properties footprint and enhancing your overall lifestyle.

Can I have a chlorine-free pool?

A truly chlorine-free pool is unlikely unless you opt for a natural pool with reed beds. Conventional pools require chlorine for hygiene, though alternative disinfection methods like ozone systems can reduce chlorine levels significantly. Saltwater pools also produce chlorine via electrolysis. In summary, chlorine is necessary to ensure water safety.

What are your pools made of?

Our pools are constructed with a reinforced concrete shell for durability, waterproofed with modern tanking systems, and finished with high-quality tiles, either mosaic or porcelain. This approach ensures long-lasting strength, water-tightness, and a premium aesthetic.

How long until I can be swimming?

For an outdoor pool, expect around 16 weeks of construction, although this can vary depending on the broader project. Indoor pools typically take longer due to dependencies on the overall build.

How do you manage humidity and air quality in indoor pools?

Managing humidity and air quality in indoor pools involves proper ventilation, dehumidification, and air handling systems. These ensure comfort and energy efficiency by maintaining air temperature slightly above water temperature and managing heat transfer.
