What Is Kohler Cast Iron Bathtub Worth?

The typical price range for Kohler Cast Iron Bathtub is $100 - $200 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The condition of the porcelain enamel, specifically the presence of chips, deep scratches, or 'crazing' in the finish.
• The presence and legibility of original manufacturing marks and numbers on the roughcast exterior.
• Overall structural integrity, including the absence of significant rust or pitting on the exposed cast iron surfaces.

How to Identify Kohler Cast Iron Bathtub?

• Look for the roughcast texture on the underside of the tub, which is characteristic of early 20th-century Kohler manufacturing.
• Check for visible manufacturing marks and specific identification numbers embossed directly into the cast iron on the bottom.
• Verify the heavy porcelain enamel coating, which should feel significantly thicker and smoother than modern acrylic alternatives.
