Acrylic is one of the most popular materials used for hot tub shells. Shells are made by thermo forming a sheet of acrylic that is reinforced with a layer of fiberglass or polyurethane.

Pros:

• Aesthetic appeal: Acrylic shells come in a variety of colors, including smooth gloss and marble textures, making them very visually appealing.

• Durability: Acrylic is highly durable and resistant to cracking, scratching, and fading. It is designed to last for years without requiring much maintenance.

• Maintenance: The surface is non-porous, so it repels dirt, mold, and is easy to clean.

• Insulation: Acrylic shells are often combined with high-quality insulation, so they maintain water temperature well.

• Comfort: The surface is pleasant to the touch, warm, and smooth.

Cons:

• Price: Typically more expensive due to its manufacturing process and high-quality surface finish.

• Scratch Sensitivity: Although the material is durable, the surface can be scratched when using abrasive cleaners (however, scratches can often be polished out).
