31" Freestanding Soaking Bathtub with 103 Gallons Total Capacity, Drain Hole Center, Non-Porous, UV, and Stain Resistant: with No Overflow Hole. Generously sized at approximately 103 gallons—exemplified by the IOS™ model, which offers exactly that volume—this tub comfortably accommodates a full-body soak for one person. Designed for efficient plumbing installation, the bathtub features a centrally located drain—perfectly balanced and ideal for standard floor and drain alignment. Constructed from Volcanic Limestone™ (also known as EnglishCast™), the tub’s surface is solid and non-porous. This ensures water—and any spills—remain on the surface, making cleaning effortless and preventing internal staining or moisture absorp. The natural material provides enhanced protection against UV exposure and staining—boasting up to three times the UV resistance of competing solid-surface materials. This keeps the tub looking bright white and pristine for years to come. Type: Bathtub. Shape: Oval. Overflow Hole: No. Finish: White. Installation Type: Freestanding. Material: Volcanic Limestone.
