72" x 36" Soaking, Whirlpool & Air Bathtubs

Why Choose a 72" x 36" Bathtub?

The 72" x 36" bathtub is widely considered the "Goldilocks" size for master bathroom renovations. It offers full 6-foot length for stretching out, yet its 36-inch width is versatile enough to fit into most standard alcoves or decks without requiring major structural changes. This size provides significantly more internal volume than a standard 30" or 32" wide tub, making it an ideal choice for a spacious, comfortable soak that doesn't overwhelm the room.
