F.A.Q

Frequently Asked Questions (FAQ) – TopZero Sinks

Material & Quality

What type of stainless steel does TopZero use?
TopZero Stainless Steel Sinks are made from premium 304 series stainless steel, ensuring durability, hygiene, and rust resistance.
 

What is the finished surface of TopZero sinks?
All TopZero kitchen sinks sold in North America feature a Soft Satin Brushed Finish, delivering a sleek, refined look.
 

What does Chrome–Nickel content mean?
Chrome enhances durability and luster, while Nickel provides strength and resistance. TopZero sinks are 18/10 stainless steel, meaning 18% Chromium and 10% Nickel for superior quality.
 

What does the gauge of stainless steel mean?
Gauge refers to the thickness of the stainless steel sheet. Lower numbers indicate thicker material—high-quality residential sinks are typically 18-gauge (1.2mm).

Are there different types of stainless steel for sinks?
Yes! Some stainless steel sinks may rust or corrode over time due to poor material composition. Corrosion resistance depends on the right mix of Chromium and Nickel content.
 

Care & Maintenance

How do I maintain the shiny look of my stainless steel sink?
Daily maintenance is essential! After each use:

1. Wipe with a soft, soapy cloth.

2. Rinse thoroughly.

3. Dry the sink to prevent water deposits.
   Recommended cleaners: Spic and Span Liquid, Lysol antibacterial cleaner, or any product containing chloride.

Can I use a rubber mat inside my sink?
No—rubber mats trap water, causing iron deposits and discoloration over time.
 

Why should I dry my stainless steel sink after rinsing?
Water contains minerals and salts that can leave spots as it evaporates. Drying prevents buildup, and white vinegar can help remove stains if needed.
 

What chemicals should I avoid on my stainless steel sink?

• Chlorine bleach & chloride-based cleaners

• Muriatic acid & silver dip cleaners

• Plumbing PVC adhesives & solvents

• Citric fruit juices, vinegar, and salt (if left for long periods)

Does stainless steel rust?
High-quality stainless steel does not rust, but surface discoloration may occur due to:

• Steel wool pads used for cleaning.

• Cast iron pots or tin-coated steel cans left in the sink while wet.

• Iron deposits from tap water.
  To remove stains, use a mild stainless steel cleaner, scrubbing with the grain of the finish.
  

  I have a scratch on my sink. How can I remove it?
  Stainless steel is durable but can still be scratched. You can blend scratches using:
  ✔ creams
  ✔ Fine Scotch-Brite pads (never use steel wool or wire brushes).
  ✔ Daily care prevents most stains—persistent rust from cookware can be removed with non-abrasive stainless steel cleaners.

  Installation & Compatibility

  Which countertop surfaces are compatible with TopZero sinks?
  TopZero sinks can be installed in:
  ✔ Granite, marble, engineered quartz countertops
  ✔ Wood butcher block
  ✔ Porcelain slabs and honeycomb/veneered natural stones

  Is a CNC or Waterjet machine required for installation?
  A precise sink cut is essential. DXF files for automated systems are available on our website to guide fabrication.

  Can TopZero sinks be installed on any countertop thickness?
  Yes! Welded sink brackets are preset for 3cm (1¼”) countertops, but spacer conversions allow for 2cm or 1.2cm installations if needed.

  Can an undermount sink be replaced with a TopZero seamless sink?
  Yes, retrofit installations are possible with proper planning and adjustments. Independent TopZero installers specialize in on-site replacements, such as those at changeyoursink.com.

  Performance & Features

  Does the seamless installation prevent water penetration?
  Yes! Non-sag acrylic adhesive fills hairline gaps between the sink and countertop, creating a watertight and non-porous bond.

  Why is my stainless steel sink undercoated?
  The undercoating helps absorb sound, prevent condensation, and maintain water temperature in the sink.

  How does TopZero compare to undermount sinks?
  
  Undermount sinks have exposed edges and require more polishing.
  TopZero seamless sinks eliminate edge chipping, provide a sleek aesthetic, and ensure maximum hygiene.
  
  What is European finish?
  A rich, deep satin-smooth finish achieved through circular pattern polishing rather than straight-line polishing.
  
  Installation Support
  
  Where can I find installation guides and videos?
  
  Watch step-by-step installation videos on www.TopZero.com and YouTube, and review our Installation Manual under the Support section.
  
  Are there certified TopZero fabricators? 
  
  Yes! We are certifying fabricators who follow recommended installation practices. Check our website for fabricators in your area or have your preferred fabricator certified upon completion.
  
  Does installation require mechanical screws or acrylic adhesive only?
  
  While acrylic adhesive creates a strong bond, mechanical screws add extra support and are required for proper installation.
  
  Does the TopZero sink installation cost more than undermount sink installation?
  
  Due to the sleek appearance and hygiene benefits, fabricators may charge more for TopZero sinks compared to traditional undermount installations.
  
  Are there different seamless edge options around the sink?
  Yes! Sink rims can be adjusted for a thinner or thicker countertop edge, allowing for a slight beveled or rounded finish.
