A. No, there are several options. The beauty of the Tub liner system is that we can identify your existing tub and make a new liner that will be vacuumed formed to the same shape of what you have in your home. Instead of tearing out 300 pounds of cast iron and making a huge mess, we will use your existing tub as a perfect base that will receive your new liner like the perfect fit of a glove. This saves you time and money with the added benefit of having an insulated tub that keeps your hot water hot. Best of all, the number one comment of satisfied customers is that it is so easy to clean and still looks like new after years of use. Can’t beat that with any other product!
