Frequently Asked Questions About Swim Spas

A swim spa is a compact, heated, all-in-one tank designed for swimming, exercise, and relaxation. They arrive fully assembled and pre-plumbed for seamless installation and feature durable, all-season cabinets. Combining traditional spa features with adjustable current technology, they can be installed above ground or partially in-ground.

Key differences from a pool:

• Year-Round Use: Unlike traditional pools which are often in-ground and can’t be used in the winter, a swim spa can be installed in your backyard or indoors for year-round enjoyment.
• Built-in Current: Swim spas feature a built-in jetted current for resistance training.
• Low-Impact Therapy: Endless Pools swim spas sold by Mainely Tubs also feature models with an underwater treadmill—excellent for low-impact physical therapy.

No driving to the pool or a gym! Owning a swim spa means you have flexibility to swim, exercise, and relax all from the comfort of your own home.

A swim spa is a versatile option that blends features of both:

• Pools are generally for recreation and swimming, require a decent amount of space, have ongoing maintenance, and are not typically heated year-round.
• Hot Tubs are much smaller, focusing on relaxation with massage jets.
• Swim Spas are more compact and can encompass everything a pool and hot tub do, plus more, depending on the model. They are used for exercise, hydrotherapy, and year-round relaxation.
