Marble Magic: How to Use Onyx Accents for a Luxurious Bathroom Makeover

Transforming your bathroom into a sanctuary of luxury and tranquillity is an aspiration for many homeowners in London, Ontario, and the surrounding areas. At Classic Granite and Marble Inc, we’ve seen a growing interest in high-end materials that pair timeless elegance with modern design flair. While marble remains a perennial favourite, onyx is quickly emerging as a stunning accent material that brings an extra layer of sophistication and visual intrigue. Discover how to harness the magic of marble and onyx to craft a luxurious bathroom retreat with this comprehensive guide tailored for our Southwestern Ontario clientele.


Why Onyx? The Allure of This Unique Stone


Onyx, a rare and visually captivating natural stone, is celebrated for its ethereal translucence and vibrant veining. Boasting a palette that ranges from creamy whites and honeyed ambers to emerald greens and dramatic blacks, onyx slabs are genuine works of art. When strategically incorporated alongside classic marble, onyx elevates bathroom spaces from beautiful to breathtaking. Its light-diffusing properties allow for breathtaking backlit features, while its patterns create mesmerizing focal points.


For homeowners in London, St. Thomas, and beyond, onyx isn’t just a surface—it's a statement. When used in bathrooms, this extraordinary stone imparts a spa-like ambiance and a sense of personalized luxury rarely found in standard remodels.


Creative Ways to Use Onyx Accents in Your Bathroom


Onyx Vanity Countertops:


Upgrade your daily routine with an onyx countertop. Its glossy surface and vibrant veining bring a unique flair compared to traditional granite or quartz. Pair a dramatic onyx vanity with elegant marble walls or floors to create layered visual interest without overwhelming the space. Our artisans at Classic Granite and Marble Inc expertly template and install countertops for a flawless fit.


Backlit Onyx Backsplashes:


For a modern, atmospheric touch, try a backlit onyx backsplash behind the vanity or bathtub. The stone’s translucence allows integrated lighting to create a soft, inviting glow, transforming routine bathroom tasks into a luxurious experience. This technique is especially effective in windowless bathrooms common throughout historic homes in London and Stratford.


Onyx Shower Niches and Sills:


Niches and window sills crafted from onyx add functional elegance. These small accents can break up expanses of marble tile, acting as jewel-like highlights that catch the eye. Our team in London and nearby towns can help you design and install these perfectly coordinated features.


Custom Onyx Tub Surrounds and Feature Walls:


If you crave a bold, sophisticated look, consider cladding your bathtub surround or a feature wall in onyx. Dramatic veining and rich coloration can serve as a stunning backdrop, transforming your bathroom into a showpiece. For balance, complement this look with classic marble vanity tops or floors for timeless appeal.


Blending Marble and Onyx for Cohesive Luxury


The key to a truly luxurious bathroom is cohesion. At Classic Granite and Marble Inc, we recommend blending the clean, classic lines of marble with the jewel tones of onyx for a harmonious effect. Use marble for primary surfaces—such as floors and main walls—while reserving onyx for accent pieces. This approach ensures that the space feels sophisticated rather than overwhelming, providing both beauty and functionality.


Our design experts work closely with you to select stones that complement each other in both colour and pattern, ensuring your new bathroom reflects your unique taste and the latest design trends. We source and fabricate everything locally in London, Ontario, ensuring quick turnaround and the highest quality craftsmanship.


Benefits Beyond Beauty: Durability and Long-Term Value


Both marble and onyx offer lasting value when professionally installed and properly maintained. Marble is renowned for its strength and timelessness, while onyx, though slightly softer, stands up to bathroom use when sealed and cared for. Incorporating these fine stones can enhance your home’s appeal, boosting resale value in the competitive Southwestern Ontario real estate market.
