Can I install a bathtub on top of this?

Hello Kathleen and thanks for your question. If you are referring to a "claw foot" bathtub, the answer is yes it can be installed on top of the vinyl floor. The flooring should really never be pinched, however, the pressure points are equally distributed in this case. For installation recommendations, we would recommend reviewing the Installation Guide (found on the carton or on the product page of the Lowe's website) prior to installation. This will also give you installation guidelines to follow, and keep from voiding your manufacturer's product warranty. Thanks again and wish you all the best with your flooring project.
