Bathtub & Spa Support: Eliminate Tub Flex & Retain Water Heat

Acrylic and fiberglass bathtubs, whirlpools, and walk-in spas frequently suffer from two common problems: flimsy subfloor flexing under human weight, and rapid water heat loss through the thin acrylic shell. Spraying or pouring Tiger Foam™ beneath the tub cavity creates a rigid, custom-molded composite base that eliminates bottom deflection, squeaking, and cracking while insulating the tub shell to keep bathwater piping hot far longer.

Key Application Benefits

  • Eliminates Tub Bottom Flex & Squeaking: Forms a rock-solid, custom-cured backing that distributes body weight across the entire subfloor, preventing spongy flex and joint failure.
  • Superior Bathwater Heat Retention: The closed-cell foam insulates the thin fiberglass shell, halting convective heat loss and keeping bathwater hot without continuous topping-off.
  • Acoustic Sound Dampening: Significantly dampens the hollow echoing sound of running tap water, jet vibration, and hollow plastic acoustics.
  • Zero Rot or Moisture Absorption: Closed-cell foam will not mold, absorb water, or decay if minor subfloor dampness occurs around bathroom drains.
