Moving Floor swimming pool

A moving floor swimming pool by Guncast is the cutting-edge solution where space is at a premium, inside or out. Sit back and relax as the swimming pool area is seamlessly replaced with a solid movable floor that can then be used as a dance function venue, play area, dining hall or gym.

Our Portfolio

For more than 50 years, our experienced team of designers, engineers, and project managers have brought ambitious projects to life, delivering inspirational swimming pool and wellness suite designs, built to exceptional quality standards. If you can dream it, we’ll design and build it (Subject to the laws of physics).

Take a look at some of our recent projects.

Pool build and construction methods

Guncast is renowned for exceptional build quality and attention to detail. We consistently deliver projects to the highest standards, using the finest materials that bring impactful designs to life. Working with clients from start to finish, our main goal is to maximise pool use and enjoyment with stunning designs that inspire year-round entertainment.

Using highly durable and versatile concrete to create the pool shell allows us to accommodate any size or shape and ensure structural integrity over a longer period, whether for individual pool builds or complex projects with hydrotherapy, plunge pools, massage jets and more. For a luxury finish, clients can choose from a range of luxury materials, such as natural stone, lavish porcelain, marble, or Italian mosaic tiling.

We have the solution for every indoor swimming pool dream and we work closely with architects, main contractors or property owners directly. Our aim is to make the swimming pool build process as efficient as possible with the least disruption to the property owners and neighbours. We also have methods to overcome all different types of access challenges or space issues, with lots of experience in London Mews properties. Our aim is always to deliver on time and on budget.

Our consultants and project managers would be delighted to hear from you and answer any questions.

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.
