“I highly recommend Marathon Bath Systems. I hired them for a major bathroom remodel, and they really delivered! Their work was top shelf perfect. They showed up every day on time and ready to work. They respected my home and kept the work site clean. Because of the quality of their work, I hired them to remodel my son’s bathroom. My son sent me a video of the completed job and all he said throughout the video was “awesome;, awesome, awesome.” We are both pleased with the work of Marathon Bath Systems. If you are looking for quality, hire them!!!!!!!”

“We have done replacement of Old jacuzzi type tub with walk in shower. Robert is a perfectionist, he gave the tile models, explained entire process, and was very informed and honest throughout the process. He is punctual in the work and made all necessary precautions for replacement and the entire process took 2 days. Quality of work is Awesome. I would recommend him for others.”

“The tub to shower conversion went great! The installers were prompt (they actually showed up a little earlier than expected) and courteous. They paid attention to details and offered suggestions that were improvements over the original plan as the installation progressed. They also put down runners to make sure my tile and wood floors didn’t get scratched. Then, when the job was done, they made sure everything was cleaned up and they hauled off all of the old waste materials and packaging. I will definitely hire them again on any future remodeling projects!”
