SanSiro Asti73C 73 x 34 inch Foam Insulated Cavity Walls Acrylic Freestanding Bathtub

The Asti73C is a sleek, Zen-inspired rectangular soaking bathtub designed for larger bathrooms where space and luxury meet. Featuring a center drain layout, this model creates a balanced, symmetrical look and offers versatile seating for taller individuals or even two bathers who prefer a spacious, deeply relaxing soak.

Its clean lines and minimalist proportions bring a modern, tranquil aesthetic that fits beautifully in both contemporary and transitional settings. At 73 inches long, it delivers significantly more legroom than the compact 59" and mid-sized 67" models, making it ideal for those who want a more expansive bathing experience.

A 4-inch-wide deck surrounds the tub, proportioned to accommodate most deck-mounted faucets. If you plan to install a deck-mounted fixture, we’ll gladly confirm compatibility. The deck also doubles as a practical ledge or seating surface, making entry and exit easier for bathers.

Despite its generous size, the Asti73C maintains a comfortable internal width. In the scale photo, a 5'8" mannequin sits with fully extended legs, demonstrating its ample soaking depth, ergonomic proportions, and the possibility of shared bathing.

For improved performance, dense foam insulation is applied to the cavity walls. This enhances heat retention and provides a solid, grounded feel, without the need to insulate the entire cavity. For installations involving a deck-mounted faucet, the deck section is left uninsulated for straightforward plumbing access.
