Thank you for sharing your feedback and for taking the time to order a sample.
To clarify from the beginning: the item description and specification on our website accurately reflect the production material, and the thickness is clearly stated on the specification page. Samples are provided to show color range, surface finish, and edge detail only. Samples are not intended to represent exact size or thickness tolerances, which are always listed separately under product specifications.
As noted on our product page, all dimensions listed are nominal, which is standard across the natural stone industry. Travertine is a natural material, and variations in thickness, color, surface texture, and edge detail are normal and expected, especially with unfilled, brushed, and chiseled-edge finishes.
For additional clarity, 18x18 travertine tiles are produced at a nominal thickness of approximately 1/2 inch across the industry. A true 3/8' thickness in an 18x18 travertine tile is not an industry-standard production and is generally not available due to structural and handling limitations of natural stone at that size.
This is precisely why we strongly recommend ordering a sample before placing a full order—to physically review the material’s characteristics prior to shipment. In this case, the sample fulfilled its purpose by confirming whether the material met your project requirements before committing to a cross-country order.
The fact that the color, brushed finish, and chiseled edge met your expectations confirms that the sample accurately represents the production material supplied by the quarry and factory.
We understand that exact tolerances can be critical for certain projects; however, natural stone is not a manufactured product, and exact thickness uniformity cannot be guaranteed.
We appreciate your feedback and wish you the best with your project moving forward.
