Vision mineral cartridge


The Vision Cartridge uses a combination of Silver, Copper and Zinc so spa users can utilize a natural and effective way to reduce the use of chemically-based water sanitation systems. The Vision Cartridge uses silver catalyst technology that kills 99.96% of impurities on contact. This mineral device compliments and enhances the ozone system and completes the D1® Water Management Systems.  One Vision Cartridge lasts up to 6 months and can reduce the need for extra chemicals by 60% for cleaner, healthier and softer water.

Available as an optional addition on top of the spa filter on any Dimension One spa.

ultralife shell



The surface of your hot tub should be the most durable and comfortable because it is the most exposed and touched part of the tub. D1’s exclusive UltraLife® material satisfies both needs with superior resistance to the effects of sunlight, chemicals, and weathering and unique, slip-resistant material unmatched by any other hot tub material. The timeless beauty of softly textured UltraLife® is easily maintained, doesn’t require special cleaning solvents, and blends with any décor or color scheme.

Available now in white or gray on ALL Collections.

Tactile Therapy

The ancient art of reflexology and acupressure have brought relief from aches and pains to millions of people around the world.

These bumps stimulate trigger points in these areas, providing you with an acupressure massage.
