Since 1977, Syn-Mar Products has operated with a straightforward mission: manufacture the highest quality grout-free shower systems and seamless vanity tops on the market, and back them with unmatched customer service. 


For plumbing wholesalers and kitchen and bath showrooms across New England, New York, New Jersey, and Eastern Pennsylvania, choosing the right manufacturing partner directly impacts your bottom line. While many manufacturers in our industry push their products through third-party sales distribution companies, we take a different approach. We sell direct to dealer partners. 


Here is a closer look at why partnering directly with our Tolland County manufacturing facility gives your showroom a distinct competitive advantage.

1. Direct Partnerships with Zero Middlemen

In the bath remodeling industry, relying on middleman distribution agencies often leads to frustrating delays, miscommunications, and unnecessary price markups. At Syn-Mar Products, we eliminate the middleman. 


When premium dealer showrooms partner with us, you work directly with the manufacturer. This means when you call with a question about a custom dimension or need an update on an order, you are speaking directly to the team overseeing the production floor. This direct line of communication ensures higher accuracy on custom orders and faster resolution times, allowing you to provide a better, more reliable experience to your contractor and homeowner clients.

2. Reliable Delivery on Our Own Trucks

Logistics can make or break a remodeling schedule. Outsourcing freight to common carriers significantly increases the risk of damaged panels, cracked bases, and delayed shipments.


To protect our products and your timelines, we deliver directly to your receiving area using our own trucks. Because we manage our own fleet, we control the handling from the moment a product leaves our loading dock in Ellington, CT, to the moment it arrives at your facility. This commitment to safe, localized logistics is why we are rapidly expanding our partnerships across Eastern New York, Northern New Jersey, and Eastern Pennsylvania. 

3. Precision Manufacturing & Custom Capabilities

Your customers are looking for premium, high-quality finishes. We deliver by maintaining strict control over our 4-step manufacturing process. 

Grout-Free Shower Systems & Custom Bases

Our primary focus is engineering beautiful grout-free shower systems and custom shower bases. Because every bathroom remodel is unique, our shower bases are designed to fit virtually any floor plan. 



Our quality starts at the batching phase, where we use precise formulas of resins, pigments, and stone fillers to ensure exact color consistency. During the casting phase, the molds are vibrated vigorously for 10-12 minutes, which forces any trapped air bubbles to escape. This results in a dense, highly durable, and structurally sound panel and base.

Seamless Vanity Tops

As a perfect complement to our shower systems, our seamless vanity tops are an essential offering for your clients. Each vanity top is expertly cast as a single solid piece with an integrated sink. This eliminates the seams where dirt and moisture typically hide, offering a flawless, easy-to-clean upgrade.

4. A Straightforward 5-Year Warranty

We are a manufacturer, not a remodeler or installer. Our sole focus is on producing exceptional materials for your contractors to install. Because we oversee every step of the precision batching, casting, and curing process, we stand firmly behind our work. Every Syn-Mar grout-free shower system and seamless vanity top comes backed by a straightforward 5-year warranty. We don't rely on gimmicks; we rely on proven craftsmanship.

For nearly five decades, Syn-Mar Products has been built on a foundation of trust, experience, and exceptional product quality. By cutting out the distribution middlemen and managing our own delivery logistics, we empower premium dealer showrooms to offer their clients top-tier custom bath solutions without the typical industry headaches.
