Kohler Greek 5.5 ft Freestanding Bathtub

Kohler Greek -- cast iron freestanding for serious soaking

The Kohler Greek (K-1184) is a freestanding oval soaking tub in cast iron -- a material choice that signals a fundamentally different bathing experience than acrylic. Cast iron retains heat approximately four times better than acrylic: a tub filled to 104 degF will stay above 100 degF for 45-60 minutes in a typical bathroom, versus 20-30 minutes in an acrylic shell. For bathers who use the tub for extended soaking, that thermal retention is the primary reason cast iron commands a price premium.

The Greek's oval form is drawn from Kohler's historic cast iron design archives -- the same basic geometry Kohler produced in the early 20th century, updated with a smoother interior profile and a lower step-in height. At 66 inches long and 36 inches wide at the shoulder with a 14-inch soaking depth, the Greek is sized for one adult bather and fits in bathrooms with at least 8 feet of floor clearance on the long axis (tub length plus 12" minimum clearance on each end).

Cast iron construction implications

Cast iron weighs approximately 350-400 pounds empty and 700+ pounds full. Before specifying the Greek for a remodel, verify floor structure load capacity with a structural engineer -- particularly for upper-floor bathrooms in wood-framed homes. Most post-1990 residential construction with 2x10 or larger floor joists can handle the load, but older construction with 2x8 joists on 16" centers may require sistering. The floor must be level to within 1/4" over the tub footprint; leveling legs are included and allow +/-3/4" adjustment.

Filler and drain configuration

The Greek requires a floor-mount tub filler -- Kohler's own floor-mount fillers (Purist, Oblo, Antique series) are engineered for this tub and integrate seamlessly. Drain configuration: center overflow, 1.5" waste connection. The center drain position means the rough plumbing must be located at the center of the tub footprint -- plan rough-in before flooring is installed, as accessing center-drain plumbing post-installation requires removing the tub. Drain trim (included): brushed nickel or polished chrome depending on variant.

Who should buy the Kohler Greek

Homeowners with budget for a premium bathroom renovation, adequate floor structure for cast iron weight, and genuine intention to use the tub for soaking rather than just showering. The Greek's installed cost of $2,500-$4,500 (tub + filler + installation) is justified by its 50+ year lifespan (cast iron properly cared for outlasts acrylic by 3-4x), its thermal retention advantage, and Kohler's reputation for enamel durability. Buyers who want freestanding aesthetics without the cost or weight can achieve a similar look with Woodbridge or Empava acrylic freestanding tubs at $800-$1,500 installed.
