Splash by Masi is a bath showroom and remodeling company on E Otterson Street in Nashua. The company says it started in 1996 as a division of MASI Plumbing and Heating and puts its own tenure at 30 years; the Better Business Bureau lists Robert Boisvert III as president of both businesses. Its pitch is that the people selling the fixtures are also the plumbers who install them. What homeowners hire them for is bathrooms - full gut-and-rebuilds, tub-to-shower conversions, tile, vanities and fixtures - with kitchen work turning up occasionally. In a July 2025 Google review a customer described upgrades to a full bath and a half bath covering floor tile, countertops, faucets and lighting, all delivered on schedule. A Nashua resident writing on Reddit in July 2025 said the company refreshed a basement bathroom and gutted the main one inside two months and showed up on time every day. Two things recur in what customers write: the schedule holds, and the house stays clean. A January 2023 reviewer who swapped a tub for a tiled walk-in shower wrote that the installers came and went like clockwork and left not a speck of dust; a September 2022 reviewer on a complete bathroom gut praised the frequent progress updates and a house and yard left impeccable each day. The design side draws similar praise, though most of it is older - a run of 2017 and 2018 reviews credits a showroom designer by name for product knowledge and layout suggestions on multi-bathroom projects. That age is the main thing to weigh. Ten of the fourteen written reviews on file date from 2015 to 2018, so the most detailed accounts of the crews describe the company as it was several years ago; the newest written accounts are from 2023 and 2025. Google's own average sits at 4.1 across 20 ratings, below the 5-star written reviews that are visible, while Houzz publishes 5.0 from 10. The BBB profile is not accredited and carries no rating at all - the bureau says it lacks sufficient information to issue one - and it still lists the older Main Street address rather than the current E Otterson Street shop. A good fit if you want a bathroom designed, supplied and installed by one outfit rather than coordinating a designer, a supplier and a plumber yourself. Before booking, ask who will actually be on site, get the schedule in writing, and confirm the New Hampshire plumbing licence of whoever does the rough plumbing.
“We used Splash in Nashua. Did a refresh of a basement bathroom and a total gut of the main bathroom. Both were done within 2 months from start to finish. They showed up on time everyday. We are really happy with the final results.”
We contracted Splash by Masi to do some upgrade work on a full bath and a half bath. Floor tiles, countertops/faucets,lights, and more. They had done some work on our old home many years ago and did a magnificent job. Well, they obviously haven't missed a beat, as the bathrooms in our new home now look fantastic after some Masi magic. They were right on schedule with everything, and all went as planned. I have to give special recognition to Michael, who was assigned to all of the projects. His workmanship is exemplary. I highly recommend Splash (and Michael) to anyone who wants their bathrooms to impress. Very happy.
They did an amazing job from picking the finishes in the showroom, to the experience of walking me through the process, tile work and customer service. I am so happy with how it all turned out. I had the tub removed, replaced with floor to ceiling tile, glass doors, all new fixtures a new vanity and toilet. Everything looks great! I would highly recommend Splash and Masi!
I was very satisfied from my first meeting to discuss replacing my tub with a tiled walk in shower. Cost was reasonable and the finished shower is fantastic. The installers came and went like clock work and when I came home from work after they finished the install, there wasn't a speck of dirt or dust anywhere. And I love how it came out! Thank you very much, Dean Robbins Bedford, NH
What a great team! Lynn, with her years of expertise, made the design quick and painless. Ed came in very organized and kept the team on track with frequent visits and updates. Zach's craftsmanship is amazing. We did a complete bathroom gut and rebuild. Zach kept us updated on the progress, always leaving the house and yard impeccable. We are very please with the results and would recommend this team without hesitation!
We initially met with Ed, who measured and explained the process and timeline which was very accurate. In the showroom, Tanya helped us tremendously with some difficult decisions and always with a patient and pleasant demeanor. Her knowledge & experience in bathroom design resulted in suggestions that proved very pleasing. We were impressed with the professionalism displayed by the three person crew remodeling our bathroom. The remainder of our home was kept clean as the crew worked respectfully and harmoniously to the extent of frequently singing together with the radio. We would not hesitate to hire this company again, in fact we have. Another division of this company is scheduled to start another project on our home in a few days.
