• A genuine training space. Length matters, and a purpose-designed lap pool allows proper laps rather than a few strokes and a turn. Swim-current systems can also be added to extend a shorter pool's training capability.

• Low-impact exercise for all ages. Swimming and water-based conditioning are well suited to rehabilitation, general fitness and healthy ageing.

• Fits more yards than you'd expect. Because lap pools are narrow, they can often run along a side boundary or the length of a rear yard, preserving space for the rest of the garden. With the right design and planning, it is often more achievable, in both space and budget, than homeowners first assume.

• Can be incorporated into a family pool or spa combo. If you would like a lap pool can also be added to a bathing section or have a spa added to the side to give a full health experience. As per the lap pools we have built below.

What to know: Overall length, depth, water temperature and heating, and where you'd like to exit the pool all shape a good lap pool design. Gas or heat pump heating extend the swimming season whilst adding a pool cover will reduce the running cost of heating outside the season.

Best suited to: fitness-focused households, long and / or narrow yards, and anyone who wants their pool used daily, not just on weekends.
