“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!”

“Professional, established conformation of time to install walk-in shower after demolition, removal of tiled walls, tub and plumbing. Organized and administered flawlessly. Helped me personally resolve a plumbing issue that was not part of the job but needed to be done while in demolition, Thank You. Kept me informed daily as to what and how install progression took place, and I must add in a timely manner, most professional installer I’ve ever hired to date. Complete, polite, comprehensive, clean and most excellent follow up . Will hire again and again. You are the best of the best ! Thanks.”

I hired Marathon to convert my elderly father's tub into a walk-in shower as he could no longer get in the tub/shower. They did the job for the amount quoted (no surprise charges), the job took only 2 1/2 days just as advertised. Their 2 workers showed up on time and worked the whole time. They also removed all the shower/construction debris from in front of the house. Bottom line, you will not be disappointed if you hire Robert and his Marathon team to redo your shower setup.

Robert and team were very patient accommodated all of the thousands of options and configuration questions we posed. When we settled on all of our choices, the installation went exactly as they predicted on the timeline. They respected our home and despite this being a possible messy process they kept things as tidy and clean as possible during the transformation of our 1950’s bathroom to a modern day luxury room!

Marathon Bath Systems did an outstanding job remodeling our bathtub to a walk-in shower. Their pricing was better than other companies and the materials they used were top notch. Robert was amazing to work with from the beginning and very knowledgeable. Slava did such quality work. Great experience and would highly recommend Marathon Bath Systems.

The crew arrived each day on time, and were very professional. In three days the work was completed. All debris and trash were hauled away. We would highly recommend Marathon Bath Systems. They work to please the customer.

We got three quotes before going with Robert and his team. During the quoting, Robert was the only person who looked at our plumbing and also recognized that we have an unusually placed fan that needed to be worked around. Robert and his team were professional, talented, and courteous. We appreciated their attention to detail when they discovered our shower ceiling wasn’t level. It is now, thanks to them. We love our new shower, highly recommend!

We decided to transform our bathtub shower to a walk-in shower. We contacted marathon bath systems. It was a very professional, diligent workforce that showed up for our transformation. The results were amazing and we are very pleased with the outcome. The best feature was the final day cleanup. There was no sign of construction debris and they left our home spotless. I recommend this company very highly.

Our first floor bathroom went from the ugliest room in the house to the show piece thanks to Robert and the crew from Marathon! We were apprehensive about dealing with contractors, but Marathon put us at ease and quickly responded to all our questions. Their prices were very reasonable and there were no additional cost for unforeseen issues. Props to Slava for his amazing craftsmanship and diligence!
