Onyx Vanity Top Highly Functional & Real Statement Maker

An onyx vanity top can transform any bathroom into a luxurious oasis. With its deep, rich color and natural pattern, onyx makes a dramatic statement while also being highly functional. In this article, we’ll explore the key benefits of onyx vanity tops, what to look for when shopping, proper care and maintenance, as well as get inspired with gorgeous bathroom designs featuring this stone.

Why Choose an Onyx Vanity Top

Onyx has long been prized in home decor and design for its rare, natural beauty. Here are some of the main reasons onyx vanity tops are a top choice for bathrooms:

Timeless Elegance

The swirling, smoky color patterns of onyx have an organic, natural look that is always in style. Onyx ranges from white to black, often with distinctive banding that gives each piece a one-of-a-kind appearance. The rich, saturated colors and variation in veining mean no two onyx slabs are exactly alike. This makes for a vanity top that is sure to become a true focal point.


Despite its luxurious aesthetic, onyx is remarkably durable. While it’s softer than granite, onyx is still resistant to scratches, chips and cracks. Its high density makes it very resilient. Properly cared for, an onyx vanity top will last for many years of daily use.

Water Resistance

Onyx has very low porosity, which means it will not easily stain or absorb water. Liquids will bead up on the surface rather than soak in. This makes onyx an ideal choice for sinks and vanities which come into frequent contact with water. The smooth polished surface inhibits the growth of mold and mildew.

Easy Maintenance

Simple care is enough to keep an onyx vanity top looking like new. Just use a mild non-abrasive cleaner and avoid harsh chemicals. Annual resealing of the surface is recommended. Compared to some other natural stone that requires more intensive maintenance, onyx is relatively easy to care for.

Luxurious Feel

Polished onyx has a smooth, glassy feel, almost like marble. Yet it’s much warmer to the touch than man-made solid surface materials. The surface is pleasingly soft underhand, without being highly porous. This luxurious tactile experience enhances the bathroom environment.

What to Look for in an Onyx Vanity Top

Onyx varies considerably in color, veining patterns and overall quality. Keep the following in mind when selecting a top:

  • Color – Consider the color that will best complement your space. Neutral shades like tan or gray are versatile. Bold dark black onyx makes a dramatic statement.
  • Veining – The distinctive veining is a desirable part of onyx’s appeal. Look for pieces with interesting yet subtle banding and color variations. Avoid tops with excessive or uniform veining as they may appear too busy or unnatural.
  • Finish – A finely polished, glass-like finish ensures beauty and easy maintenance. Make sure the top has a smooth, consistent polish across the entire surface. Avoid pits or dull spots.
  • Thickness – A standard thickness is 3cm for bathroom vanity tops. Go thicker for a more durable and stable surface. Edges should have a finished bullnose for a refined upscale look.
  • Sealer – Onyx is porous and must be professionally sealed to prevent staining and damage. Ensure any top you choose has been properly sealed prior to installation. Ask about ongoing sealer maintenance requirements.
  • Installation – Onyx is fragile so should be installed by an experienced professional. Make sure edges are well supported to prevent cracking.
  • Maintenance – Confirm that the onyx is non-abrasive cleanser safe. Using the wrong chemicals can etched or dull the finish.

Caring for Your Onyx Vanity Top

While durable, onyx still requires some basic care to maintain its polish and prevent damage:

  • Clean frequently with a soft cloth and mild non-abrasive cleanser or stone soap. Avoid harsh bathroom cleaners and chemicals.
  • Rinse off any spills immediately to prevent possible staining. Blot with a towel rather than wiping.
  • Reseal the onyx annually using a stone sealer made for onyx or travertine. This prevents stains and fills microscopic pits in the surface.
  • Avoid putting hot items like curling irons or hair dryers directly on the onyx. Use a heat pad or trivet.
  • Don’t let toiletries like perfume, oils or makeup sit on the surface. Chemicals in these products can stain or etch the onyx.
  • Use a cutting board rather than cutting directly on the onyx. Knives canscratch and damage the surface.
  • Dust occasionally with a soft dry cloth. For dried water spots, use a damp melamine foam eraser then reseal.

With proper care, an onyx vanity top will maintain its stunning appearance for many years while providing daily luxury. Be sure to follow the manufacturer’s specific maintenance recommendations.
