Our house was built in 1924 and the bathroom has subway tile and an old cast iron tub. We considered gutting the bathroom and starting over, but after seeing tub and tile refinishing on HGTV, we decided to try it. The Protub guys did an amazing job. All the chips, cracks, and missing grout were repaired. And the glossy finish is perfect – just like new! And at a fraction of the cost of total renovation.
