Fiberglass:<?xml:namespace prefix = o />

- Gelcoat material is sprayed onto a mold to provide the shape of the product.

- A fiberglass and resin mix is applied to the gelcoat layer to provide strength.

- The product is then rolled out to remove air bubbles between the gelcoat and FRP (Fiberglass Reinforcement Product) layers; this prevents air voids which can cause cracks.

- Wood reinforcement and foam strips are placed on the flooring and wall areas to add strength and stiffness to the product.

- The product is then given an another FRP layer to add strength.

- The unit is removed from the mold and sent to the trim, drill and grind area where excess material is trimmed and the holes are drilled for the grab bars, drain, overflow and whirlpool jets.

Acrylic:

- An acrylic sheet is warmed in an oven, then placed in a vacuum mold. Air is removed from the mold and the acrylic takes the shape of the mold.

- A fiberglass and resin mix is applied to the acrylic layer to provide strength.

- The product is then rolled out to remove air bubbles between the acrylic and FRB layers; this prevents air voids which can cause cracks.

- Wood reinforcements are placed on the flooring and wall areas to add strength and stiffness to the product.

- The product is then given another fiberglass layer to add strength.

- Lastly, the unit is sent to the trim and drill area where excess material is trimmed and the holes are drilled for the grab bars, drain, overflow and whirlpool jets.
