Hot Tub Shells


Hot Tub Shells by Dimension One Spas

Dimension One Spas offers 8 nature-inspired acrylic colors made from premium materials. All shells are backed with ABS plastic which securely reinforces the shell strength and durability. All acrylic shells are covered by a seven year structural and surface warranty.

Unlike typical spa manufacturers, D1 uses an Elastocast® process to structurally reinforce the shell and prepare a smooth surface for jet mounting. This high density polyurethane-based product moves better with the shell during thermal expansion and contraction which prevents cracking and delaminating as well as enhancing thermal insulation and durability. D1 ensures that each shell is uniformly treated by using an automated robotic application to produce a consistent, high quality structural insulation that is better for the environment than typical fiberglass/resin systems.

  • DS_Shells Desert Stone Natural rock shades blend with calming swirls for a tranquil oasis that complements most backyard color schemes.
  • SM_Shells Smoked Marble Dark charcoal shades, deep browns and wisps of white make up this rich, luxurious color.
  • BT_ShellsBlue Topaz Reminiscent of fun days in the sun, this color is bold and tropical with waves of dark and light blue mixed with iridescent greens.
  • GM_Shells Gray Marble A smooth texture with smoky tones and natural swirls makes every shell unique.
  • S_Shells Sand This classic hot tub shell features textured grains in brown tones reminiscent endless strands of beach and salty waves.
  • MS_Shells  Moonstone Soft, modern and classy, Moonstone’s pearly white composition creates timeless beauty.
  • Ss_Shells Sunstone Like a gemstone, the warm glow of this radiant opalescent color will shine day or night as light dances off every curve.
  • O_Shells Obsidian Dark and mysterious, this deep black features multi-dimensional flakes that sparkle. Combine this color with any shade skirt for a bold and dramatic look.


D1’s exclusive UltraLife shell has superior resistance to the effects of sunlight, chemicals, and weathering, making it the obvious choice for those who want the most durable shell on the market. The timeless beauty of softly textured, non-slip UltraLife is easily maintained, doesn’t require special cleaning solvents, and blends with any décor or color scheme. At night, your spa can take on any mood or color that you choose as UltraLife white reflects light beautifully.

Because traditional spa shell materials had proven that they weren’t as tough as some alternative polymers, Dimension One Spas worked with Bayer®, the largest and most respected chemical manufacturer in the world. Together we produced an exclusive polymer formula with unparalleled strength. This high-performance spa shell material is specifically designed to endure the harsh realities of the spa environment and is the most durable and practical spa shell material available.

UltraLife is the only shell that carries a Lifetime Warranty* on its structure and surface. With UltraLife you have peace of mind knowing that if the spa should ever crack, blister or delaminate, it will either be repaired or replaced. Complete details are available at your nearest authorized Dimension One Spas dealer.
