A major programme of investment from both Cardiff Council and GLL is nearly completed to help transform Pentwyn Leisure Centre, delivering modern, inclusive and high-quality facilities for the local community.
Main Pool
Cardiff Council has been working over the past two years to completely rebuild the swimming pool at the centre. The new 25m x 13m pool features state-of-the-art technology, including two movable floors — the first facility of its kind in the UK. This innovative design enables a wider range of swimming activities and improve accessibility for all abilities, with adjustable depths ranging from 0.0m to 1.8m.
Slide
The new aquatic offer includes a separate slide area for younger children, creating additional opportunities for fun and family-focused activity.
Check out the swimming timetable to discover the new sessions available which includes a brand-new slide and splash activity. The session includes access to the Splash Pad with Water Jets (suitable for all ages), and family fun (Pool Admittance rules apply) with slightly deeper water 0.6m with balls and pool noodles and fun floats.
Gym and Studio
Alongside this, GLL has invested in the health and fitness provision. The gym has undergone a full refurbishment, with the space being reconfigured back into the main activities hall to accommodate a larger range of equipment with dedicated workout zones. This redevelopment provides members with a more spacious and versatile fitness environment, designed to support a wide variety of training styles and fitness goals.
Follow the move into the main hall, the old gym gas been converted back into a dedicated fitness class studio boasting all your favourite fitness classes every week.
Better Swim School
From 7th September 2026 we'll be introducing Better Swim School into the pool. As one of the leading swimming lesson providers in the UK we're pleased to be launched Better Swim School into Pentwyn Leisure Centre's brand-new pool. The lesson structure helps children and adult build their confidence and skills in the water. You can find out more by tapping the button below.
There's still more to come
In addition, since April this year, Cardiff Council has also been investing in the main reception area, reconfiguring the space with customers and members in mind to create a more welcoming, accessible and efficient arrival experience. We'll be sure to keep this page up to date with confirmed dates of reopening the final area of Pentwyn Leisure Centre.
