Guncast can create a high-quality indoor pool house in an existing space, or develop a new standalone plot for an indoor home swimming pool. With the addition of contemporary sliding doors and retractable ceiling, we can design and install an indoor outdoor pool for year-round enjoyment, including warmer months.
Moving floor indoor pool designs
An outside or inside pool with moving floor by Guncast is a modern solution with desirable features, where space is at a premium. Suitable for outdoor and indoor all weather swimming, the state-of-the-art technology seamlessly moves a solid floor for use as a function venue or play area, while bespoke mood lighting can give an indoor pool house extra dynamism.
Basement indoor pools and garden excavations
Particularly in London, Guncast has designed and built many pools in basements or as part of a garden excavation. Bathers can use indoor pools for a range of swimming activities for all ages. Unlike outdoor pools, indoor pools are less vulnerable to damage from natural elements that can impact maintenance costs.

Indoor Swimming Pools: Your questions answered
Is planning permission needed for an indoor swimming pool?
In most cases, planning permission is not required in the UK if it is within an existing building. However, if you are constructing a new building or extension to house the pool, planning permission may be necessary.
How often does an indoor pool need maintenance?
Regular maintenance is essential, typically involving professional cleaning and chemical balancing every few weeks to keep your pool in the best condition.
What Is the Difference Between Deck Level, Freeboard, and Infinity Pools?
Freeboard pools have water below the edge, ideal for simple designs. Deck level pools have water flush with the deck, providing a sleek look but are more complex. Infinity pools create an illusion of water extending to the horizon, ideal for scenic views but are the most costly and complex to build.
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.
Do You Need Planning Permission for Pools?
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.
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.
What Is the Life Expectancy of Your Pools?
Our pools are designed for long-term durability, with a concrete shell that can last several decades. We offer a 10-year warranty on the shell, 3 years on finishes, and 1 year on filtration systems. Proper maintenance ensures your pool remains a lasting investment.

Swimming pool water quality and plant
Water quality and management is fundamental to pool design making the plant room and technology an important factor in the overall pool design and build. Our three premium filtration packages (Guncast Smart, Guncast Premium, and Guncast Sustainable) have been designed and developed to suit high-end residential indoor and outdoor swimming pools.
The Guncast Pools and Wellness filtration packages help reduce the amount of chemicals needed for the water treatment of your pool, which is not only good for you, but also better for the environment.
