When choosing an outdoor spa, is it best to combine it into the main pool design? Or are standalone units a better choice? From integrated designs to standalone models, we look at the different ways to incorporate pools and spas into your outdoor area design.

What could be more relaxing than soaking in the warm bubbles of a spa after a few laps in your own backyard swimming pool? Pools and spas make a great combination, but there is plenty to consider before choosing a spa design set-up. There is a range of outdoor spa options, including swim spa units, integrated spas (as part of the swimming pool) and hydrotherapeutic standalone models. Pool and spa specialist Andrew Pullen talks us through some of the differences in spa designs and types.

"Swim spas, where you have spa seats at one end and a swim zone with swim jets at the other end, are becoming extremely popular," Andrew says. Swim spas are sold as a complete unit and offer the facilities to combine exercise with relaxation. Swimming against adjustable jets, users can get an intense workout and a warm soak all at once, and without taking up too much room in the backyard.

Many people are still keen to combine a small, integrated spa with their in-ground pool, affording them views across the main pool as they relax. However, one disadvantage of having pools and spas integrated is the difficulty of setting up heating and jets separate from the main pool.

"Aesthetics are really the only advantage of combining the two in this way," says Andrew. "In fact, having a spa that’s part of a pool is usually very costly to install and maintain, and you are limited in the amount of hydrotherapy jets that you can incorporate."

Real choice and flexibility comes with a standalone spa. Although the visual result may not be as tidy as with integrated set-ups, a standalone model should ensure you get all the features you are looking for. Far from being just a small pool to warm up in, a good standalone spa can offer so much in the way of relaxation, stress relief and general wellbeing.

Outdoor spas can typically seat between two and 12 people, depending on their size. Newer models come with a range of features, such as UV water-sanitising systems and energy-efficient heaters. And gone are the days when pumping up the jets would give the neighbours a headache. Insulated interiors are designed to muffle the noise of jets.

Of course, cost may also determine which spa design set-up you choose. There are a lot of variants involved, so shop around.
