The VCS-1013 white oval porcelain undermount sink is made from true vitreous china which is triple glazed and triple fired to ensure your sink is durable and strong. Undermounting a bathroom sink creates a sleek look and allows for more space on your countertop. The overall dimensions for the VCS-1013 are 12 1/4″ x 15 1/8″ x 7 1/8″ and require an 18″ minimum cabinet size.

Vitreous China VS. Porcelain: What's the difference? 

There is a decent amount of confusion when it comes to the differences between vitreous china and porcelain. 

Are they two different materials or the same material with different names?

To state it simply and clarify, vitreous china and porcelain are made from the same exact materials; vitreous china is simply the glazing technique that is added onto porcelain for that sleek, shiny look you see on common bathroom sinks and toilets. 

How Porcelain is Made

Porcelain is made by cooking ceramic materials such as clay, feldspar, and silica, at very high temperatures to achieve the desired look. 

What we mean by “desired look” is really between a glazed or unglazed look.

Glazed or Unglazed?

The most popular and frequently seen unglazed porcelain is commonly called bisque or biscuit porcelain, named after its light tan, off-white coloration. 

Whether or not you want a glazed or unglazed finish is completely dependant on the manufacturing process, specifically, what is called the firing process. 

For unglazed styles, such as our VCS-1114B Vanity Sink, the firing process begins by heating up the inorganic materials of clay, feldspar, and silica to harden them. For unglazed styles, the process stops here. 

You are then left with a very raw, organic-looking finished product that can be fitting for a rustic or vintage bathroom decor such as a modern-day farmhouse. 

For glazed styles, such as vitreous china, they are subjected to a second firing process to achieve a much higher temperature. 

Once the right temperature is reached, a stain-resistant enamel liquid glass coating is applied on top of the porcelain. 

As a result, you are left with the beautiful finished product we know as vitreous china. 

The smooth vitreous enamel surface of vitreous china offers many benefits that unglazed sinks do not, hence the reason why glazed styles are more popular today. 

A few of the biggest benefits of glazed sinks are that the gloss enamel coating acts as a protective casing making it more resistant to scratches, more sanitary, and more durable. 

For these benefits, vitreous china is commonly the choice product for not only individual’s homes but industrial and commercial infrastructures as well as they generally last longer. 

Caring For Your Porcelain

As a general rule of thumb, you should try to clean your porcelain sinks on a daily basis, if not, weekly to prevent soap scum and other bacterial buildups. 

Try keeping a washcloth or sponge near your sink at all times so you can easily wipe down the inside of the porcelain bowl as you wash your hands or perform other daily chores over the sink. 

You should avoid abrasive cleaners! Porcelain is durable, however, if you’re trying to maintain and extend the lifetime of your porcelain sinks, abrasive cleaners will do the exact opposite as they are too harsh for porcelain products. 

For a deep clean, line your sink bowl with layers of paper towels and pour over bleach, covering all areas of your sink. After roughly 15-30 minutes, remove towels and rinse the bowl with water. This should remove any soap scum and other stains you may have tarnishing your porcelain sink bowls.

How to clean your bathroom sinks and faucets? 

Your bathroom comes in contact with a lot of elements on a daily basis aside from just water. Faucets are easy places for dirt, soap, and calcium buildup to accumulate causing your faucet to look unappealing. Luckily, cleaning up your bathroom or kitchen faucet is easily accomplished. In fact, most of the materials should already be in your home already.

Here’s what you’ll need:

  1. Water
  2. Washcloth
  3. Toothbrush
  4. Cleaning vinegar 
  5. Dish soap
  6. Non-abrasive cleaner

Steps To Clean Faucets

  1. Start by checking faucet material. This is pretty self-explanatory and quite honestly, in most cases doesn’t even need to be done since most faucets are constructed with durable materials to withstand most cleaning chemicals. Yet, it doesn’t hurt to check since there are some cases where chemicals can warp or alter the finish of your faucet. 
  2. Begin by performing a light, initial scrub. With a damp washcloth, apply a small amount of dish soap onto the cloth and lather it around until you see substantial foam and bubbles forming. Then, simply rub the cloth around the surfaces of your bathroom faucet, making sure to get every area, especially between faucet handles. Rinse the soap off with water. 
  3. Don’t forget about the edges. One of the most important areas to clean is the edges where the faucet base meets the sink. This area is a hotspot for grime and dirt so it’s crucial to clean these spots regularly. This is where an old toothbrush will comes in handy. Grab your toothbrush and scrub away.
  4. Apply cleaning vinegar. If you finished steps 1-3 and still see some visible dirt or markings, try applying a water-vinegar solution with equal parts water and vinegar. The acidity of the vinegar should aid in removing some of those hard to get rid of marks. 

Steps To Clean Bathroom Sink Bowl

For the bowl of your bathroom sink, using bleach or other chemicals is not recommended. Try opting for a non-abrasive cleaner such as Bar Keeper’s Friend® for sink bowl cleaning. BKF is safe to use on stainless steel, porcelain, and most solid surfaces.

Perfect small sink basin

This was just what I needed. My supplier did not have a sink this small (just 10 inches deep), so I had to find this online. It's now installed and appears to be high quality and duarable.
