Proflo Undermount Sink

Transforming Your Kitchen or Bathroom with the Perfect Undermount Sink

When I renovated my kitchen last year, I spent countless hours researching the perfect sink. After weeks of comparison shopping and visiting showrooms, I finally settled on a Proflo undermount sink—and I couldn’t be happier with my decision. If you’re considering a similar purchase, I’ve compiled everything I learned along the way into this comprehensive guide to help make your decision easier than mine was!

As someone who’s now installed Proflo undermount sinks in both my kitchen and guest bathroom, I’m excited to share my experiences and insights. Whether you’re a first-time homeowner, a seasoned DIY enthusiast, or simply looking to upgrade your existing fixtures, this guide will walk you through everything you need to know about Proflo undermount sinks.

What Are Proflo Undermount Sinks?

Before diving into specifics, let’s clarify what makes an undermount sink different from other types. Unlike traditional drop-in sinks that have a visible rim resting on the countertop, undermount sinks are installed beneath the counter surface. This creates a seamless transition from countertop to sink and eliminates that problematic rim where dirt and debris tend to collect.

Proflo, as a brand, has been making waves in the plumbing fixture industry for years, offering quality products at competitive prices. Their undermount sinks have become increasingly popular among homeowners like me who want that high-end look without the premium price tag.

Material Matters: What Proflo Undermount Sinks Are Made Of

One of the first considerations when purchasing any sink is the material, and Proflo offers several options to suit different needs and preferences.

Stainless Steel

Proflo’s stainless steel undermount sinks are by far their most popular offering, and for good reason. The 18-gauge and 16-gauge options provide excellent durability while maintaining a sleek, modern aesthetic. My kitchen sink is a 16-gauge stainless steel model, and after a year of heavy use, it still looks practically new.

What I particularly appreciate about their stainless steel options is the brushed finish, which hides water spots and fingerprints much better than a polished finish would. Trust me, with three kids constantly using the sink, this feature alone has saved me countless hours of cleaning!

Fireclay

For those seeking a more traditional look, Proflo’s fireclay undermount sinks offer timeless appeal. These sinks are made by molding clay at extremely high temperatures, resulting in a non-porous surface that’s resistant to stains, scratches, and chemicals.

My sister installed a fireclay Proflo undermount sink in her farmhouse-style kitchen renovation, and the classic white apron-front design has become the centerpiece of her space. She particularly loves how the material maintains its brightness even after years of use.

Composite Granite

Proflo also offers composite granite undermount sinks, which blend crushed granite with resin to create an incredibly durable material. These sinks are available in various colors, allowing for greater customization in your kitchen or bathroom design.

A friend of mine chose a black composite granite Proflo sink for her kitchen remodel, and it pairs beautifully with her light quartz countertops. She raves about how resistant it is to heat, stains, and scratches—even with her family of five using it daily.

Cast Iron

While less common in their lineup, Proflo does offer some cast iron undermount sink options. These sinks feature a layer of porcelain enamel fused to a cast iron core, providing exceptional durability and heat retention.

Cast iron sinks do require more maintenance and care than their stainless steel counterparts, but many homeowners feel the classic look is worth the extra effort. Just be aware that these sinks are significantly heavier and may require additional support during installation.

Sizing Up Your Space: Dimensions and Configurations

Proflo undermount sinks come in a variety of sizes and configurations to accommodate different spaces and needs. Before making a purchase, I strongly recommend measuring your existing cabinet base and considering how you typically use your sink.

Single Basin vs. Double Basin

One of the biggest decisions you’ll need to make is whether to go with a single basin or double basin design. Proflo offers both options in various sizes.

I opted for a large single basin in my kitchen (33″ x 22″), which gives me plenty of space for washing large pots and pans. The uninterrupted space has been incredibly practical for my cooking habits. However, my mother-in-law swears by her double basin Proflo sink, as she likes to keep washing and rinsing areas separate.

For those who can’t decide, Proflo also offers 60/40 and 70/30 split options, providing one larger basin and one smaller one. These hybrid designs offer the best of both worlds and have become increasingly popular in recent years.

Standard Dimensions

Here’s a quick overview of some common Proflo undermount sink dimensions:

• Small single basin: 15″ x 13″ (great for bathrooms or small kitchens)
• Medium single basin: 23″ x 18″ to 25″ x 22″
• Large single basin: 30″ x 18″ to 33″ x 22″
• Double basin: 31″ x 20″ to 33″ x 22″ (with various basin split options)

Remember that these measurements typically refer to the overall sink dimensions, not the interior basin size. The actual usable space will be slightly smaller.

Depth Considerations

Another important dimension to consider is depth. Proflo undermount sinks typically range from 7″ to 10″ deep.

I chose a 9″ deep sink for my kitchen, which provides ample space for filling large pots while still maintaining comfortable ergonomics. However, if you’re shorter in stature or have back issues, you might prefer a shallower model to reduce strain from bending over.

For bathroom applications, Proflo typically offers shallower options (5″ to 7″), which are more appropriate for handwashing and typical bathroom tasks.

Installation: Bringing Your Proflo Undermount Sink Home

Installing an undermount sink isn’t a simple DIY project for most homeowners, myself included. When I purchased my Proflo sink, I hired a professional for the installation, and I’d recommend the same for most people.

Installation Process Overview

While I didn’t perform the installation myself, I did observe the process, which typically follows these steps:

1. The countertop is templated with the sink in place to ensure perfect alignment
2. The countertop material is cut precisely to the sink dimensions, with appropriate reinforcement added if necessary
3. The sink is attached to the underside of the countertop using special clips and silicone adhesive
4. The countertop with attached sink is installed on the cabinets
5. Plumbing connections are made, including drain assembly and faucet installation

The entire process took about three hours for my professional installer, though more complex installations might take longer.

Mounting Hardware

One thing I appreciated about my Proflo undermount sink was that it came with all necessary mounting hardware. The package included specialized clips designed to securely fasten the sink to different countertop materials, as well as detailed installation instructions.

However, depending on your countertop material, your installer might prefer to use a different mounting system. This is particularly common with natural stone countertops, where special considerations must be made to ensure proper support.

Countertop Compatibility

A common question I had before purchasing was whether a Proflo undermount sink would work with my countertop material. Through my research, I learned that Proflo undermount sinks are compatible with most solid-surface countertops, including:

• Granite
• Marble
• Quartz
• Solid surface (like Corian)
• Concrete

However, they are not recommended for laminate countertops without special modifications. This is because laminate typically has a particle board core that can deteriorate when exposed to moisture, which is inevitable at the cut edge around a sink.

If you have your heart set on an undermount sink with laminate countertops, you’ll need to work with a specialized fabricator who can create a waterproof seal and proper support system—which significantly increases the cost and complexity of the project.

Maintenance and Care: Keeping Your Proflo Sink Looking New

After investing in a quality sink, you’ll want to keep it looking its best for years to come. I’ve developed a simple maintenance routine for my Proflo undermount sink that has kept it in excellent condition.

Daily Cleaning

For stainless steel Proflo sinks, I simply wipe the surface with a soft cloth and mild dish soap after each use, then dry it with a microfiber cloth to prevent water spots. For tougher residue, a paste of baking soda and water works wonders without scratching the surface.

For fireclay and composite sinks, daily cleaning is similarly straightforward—warm water and mild soap are usually sufficient. However, I recommend avoiding abrasive cleaners and scrubbers that could damage the finish over time.

Preventing Scratches and Stains

While Proflo sinks are designed to be durable, no sink is completely impervious to damage. I use a sink grid in my kitchen sink to prevent pots and pans from directly contacting the bottom surface, which has been effective at preventing scratches.

For stain prevention, prompt cleaning is key—especially for items like coffee, tea, and tomato sauce that can discolor surfaces if left to sit. I’m particularly careful with my sister’s white fireclay sink, where stains would be more noticeable.

Long-term Care

Every few months, I give my stainless steel sink a deeper cleaning using a specialized stainless steel cleaner that helps restore its original luster. For the composite and fireclay sinks in my family, periodic applications of a sink wax or sealant help maintain their resistance to staining and make daily cleaning easier.

One maintenance tip I wish I’d known earlier: avoid leaving wet sponges or cloths in the sink, as they can trap moisture against the surface and potentially cause discoloration over time. I now keep a small holder next to my sink for this purpose.

Sound Considerations: The Quiet Revolution

One aspect of sink selection that’s often overlooked is sound. Washing dishes or running water in a thin, non-insulated sink can create significant noise that reverberates throughout the kitchen. Fortunately, many Proflo undermount sinks address this concern.

Soundproofing Features

Most of Proflo’s stainless steel undermount sinks come with sound-dampening pads or coatings applied to the underside. My 16-gauge kitchen sink features thick rubber padding that noticeably reduces noise compared to my old drop-in sink.

Higher-end models in their lineup feature more comprehensive sound dampening, with coverage extending further up the sides of the basin. If your kitchen has an open concept layout like mine, where sink noise can travel throughout living spaces, I’d recommend investing in a model with enhanced sound insulation.

Fireclay and composite sinks naturally dampen sound better than stainless steel due to their denser construction, so additional soundproofing features are less common (and less necessary) with these materials.

Drain Assembly and Accessories

When purchasing a Proflo undermount sink, it’s important to note that most models do not include a drain assembly in the standard package. This allows you to select the specific style and finish that matches your faucet and other fixtures.

Drain Compatibility

Proflo sinks are designed to work with standard 3.5″ drain assemblies, which are readily available at any home improvement store. I chose a brushed nickel drain to match my faucet, but you could opt for chrome, oil-rubbed bronze, or other finishes to complement your kitchen or bathroom design.

For kitchen applications, Proflo undermount sinks are fully compatible with garbage disposals. My installer had no issues connecting my existing disposal to the new sink, though the process did require purchasing an appropriate flange adapter.

Accessory Options

Beyond the basic sink, Proflo offers several accessories that can enhance functionality:

• Sink grids (which I mentioned earlier for scratch protection)
• Cutting boards designed to rest on the sink rim
• Colanders that fit within the basin
• Soap dispensers that can be mounted through an existing faucet hole

While these accessories aren’t included with the sink purchase, they’re worth considering as add-ons to maximize the utility of your new fixture.

Price Range and Value Proposition

One of the primary reasons I chose Proflo for my undermount sink was the excellent value it offered. While pricing varies depending on size, material, and features, here’s a general range of what you might expect to pay:

• Basic stainless steel models: $200-$400
• Premium stainless steel with enhanced features: $400-$700
• Fireclay sinks: $500-$900
• Composite granite sinks: $300-$600
• Cast iron models: $400-$800

These prices are typically 20-40% lower than comparable models from premium brands, while still offering similar quality and features. In my experience, the difference in quality between my Proflo sink and my neighbor’s much more expensive brand is negligible in daily use.

Remember that these prices generally don’t include installation, which can add $200-$500 depending on your location and the complexity of the job. If you’re replacing countertops at the same time (as most undermount sink installations require), that will be an additional significant expense.

Where to Purchase a Proflo Undermount Sink

Proflo products are primarily sold through plumbing supply stores and select home improvement retailers. I purchased mine through a local plumbing supply house, which I’d recommend if possible. The staff there provided valuable advice that helped me select the right model for my needs.

If you prefer online shopping, several authorized retailers sell Proflo products through their websites. Just be sure you’re buying from an authorized dealer to ensure you receive the full manufacturer warranty.

Speaking of retailers, many offer display models you can see in person before purchasing. I found this extremely helpful in comparing gauge thickness, sound dampening, and overall quality between different models. There’s simply no substitute for being able to see and touch a product before making such a significant purchase.

Comparing Proflo to Other Brands

When I was shopping for my undermount sink, I compared Proflo to several other popular brands. Here’s how they stacked up in my assessment:

Proflo vs. Premium Brands

Compared to high-end brands like Kohler and Blanco, Proflo offers similar construction quality and features at a lower price point. The primary differences I noticed were in the variety of specialized designs and premium finishes available—the premium brands simply offer more options, particularly for unusual sizes or configurations.

However, for standard sizes and common materials, the functional differences were minimal. My Proflo sink has the same gauge stainless steel, similar sound dampening, and comparable warranty to models costing hundreds more.

Proflo vs. Budget Brands

On the other end of the spectrum, Proflo outperforms most budget brands in terms of material thickness, sound insulation, and overall durability. The lowest-priced sinks I looked at had noticeably thinner steel, little to no sound dampening, and limited or no warranty coverage.

Given that a sink is something you’ll use multiple times daily for many years, the modest price difference between Proflo and the absolute cheapest options seemed like a worthwhile investment in quality and longevity.

The Warranty Factor

Speaking of longevity, warranty coverage is an important consideration for any fixture purchase. Proflo stands behind their undermount sinks with a limited lifetime warranty for residential use, which covers defects in materials and workmanship.

This warranty was a significant factor in my decision to purchase a Proflo sink. While I haven’t needed to make a claim (a good sign in itself!), knowing that the company stands behind their products gave me confidence in my investment.

It’s worth noting that the warranty doesn’t cover normal wear and tear, improper installation, or damage from misuse. To maintain your warranty coverage, be sure to follow the care instructions provided with your sink and keep your proof of purchase in a safe place.

Versatility: Kitchen and Bathroom Applications

One of Proflo’s strengths is their diverse range of undermount sinks suitable for both kitchen and bathroom applications. I’ve now installed their products in both spaces in my home.

Kitchen Applications

In the kitchen, Proflo’s larger single and double basin models provide ample space for food preparation, dishwashing, and cleanup. The deeper basins (8″-10″) are particularly useful for filling large pots or soaking baking dishes.

The durability of their kitchen sinks is impressive—after a year of daily use including dropping heavy pots, exposure to hot cookware, and contact with acidic foods, my sink shows virtually no signs of wear.

Bathroom Applications

For bathroom vanities, Proflo offers smaller undermount sinks designed specifically for this application. These typically feature shallower basins (5″-7″) and more compact dimensions to fit standard vanity cabinets.

I installed a small oval Proflo undermount sink in my guest bathroom, and it perfectly complements the marble countertop. The undermount style creates a clean, seamless look that makes the small space feel more open and is much easier to keep clean than the old drop-in sink it replaced.

Real-World Experiences: User Reviews

Before making my purchase, I scoured online reviews and spoke with friends who owned Proflo products. The consensus was overwhelmingly positive, with most users citing excellent value, good quality, and attractive design as key advantages.

Common praise in reviews focused on:

• Durability and resistance to scratching
• Effective sound dampening (particularly in stainless steel models)
• Ease of cleaning and maintenance
• Attractive appearance that integrates well with various kitchen styles

The few negative reviews I found typically centered around installation issues (which often seemed to result from improper installation rather than product defects) or disappointment that drain assemblies weren’t included.

After owning and using my Proflo undermount sink for over a year, I can confidently say my experience aligns with the positive reviews. The sink has performed exceptionally well for daily family use, and I’ve recommended the brand to several friends who were planning kitchen or bathroom renovations.

Making Your Final Decision

After exploring all these aspects of Proflo undermount sinks, you hopefully have a clearer picture of whether this brand is right for your needs. As with any significant home improvement purchase, I recommend taking your time with the decision and considering how the sink will function in your specific lifestyle.

Ask yourself:

• How do I primarily use my sink? (Food prep, dishwashing, pot filling, etc.)
• What aesthetic am I trying to achieve in my kitchen or bathroom?
• What’s my budget for the entire project, including installation?
• How important are features like sound dampening and scratch resistance?
• Do I prefer the convenience of a double basin or the spaciousness of a single basin?

By thoughtfully considering these questions, you’ll be well-equipped to select the perfect Proflo undermount sink for your home.

My Personal Verdict

After living with my Proflo undermount sink through countless family meals, holiday cooking marathons, and everyday use, I can confidently say it was an excellent choice for my home. The combination of quality construction, attractive design, and reasonable price point has made it one of my favorite elements of my kitchen renovation.

If you’re considering a Proflo undermount sink for your own project, I hope my experience and this comprehensive guide have been helpful. While no product is perfect for everyone, Proflo’s range of options means there’s likely a model that will suit your specific needs and preferences.

Remember that the sink is truly the workhorse of your kitchen or bathroom, used multiple times daily by everyone in your household. Investing in quality here pays dividends in daily satisfaction and long-term durability—something my Proflo sink continues to deliver.

Whether you’re building a new home, renovating an existing space, or simply replacing an aging fixture, a Proflo undermount sink deserves serious consideration. With their combination of quality materials, thoughtful design, and competitive pricing, they offer a compelling option for today’s homeowners.

Happy renovating!
