Relax in a KOHLER Rve 67” x 31-1/2” rectangular undermount/drop-in bath crafted with strong geometric lines and a low step-over design that makes it easy to enter and exit. The slotted overflow ensures whole-body immersion with maximum water depth. Sturdy cast iron construction and Safeguard slip-resistant surface offer long-lasting performance. The exterior ground coat surface is minimally enhanced and painted to capture as much of the raw elements of the cast iron material.
