Great experience!

“LJ Stone came in and replaced our shower/bath with a new shower. The installer came in and to be honest, we hardly new they were here. It only took them a day and a half, and the next day I enjoyed a nice warm shower. What impressed me most was how clean they were in the process. For taking out an old tub, and doing a bit of drywall work there was virtually no cleaning we needed to do behind him. The only way you knew he had been here was the wonderful shower he left behind. Great experience!”

Rob H.

Would highly recommend LJ Stone!

“Excellent experience from beginning to end! They removed our old bathtub/shower surround and installed a new bathtub/shower with glass door and did a fantastic job. Looks even better than we imagined and has completely updated the look of our bathroom. High quality materials and a very rich look. Everyone was very friendly, professional, informative and kept us updated throughout the installation process. Would highly recommend LJ Stone!”
