Natural & Engineered Stone
Thresholds
Types of Thresholds
Thresholds aren’t just transition pieces—they are functional design elements that protect and enhance flooring junctions. At Petros® Stone, we offer various types to suit different applications:
Standard Threshold – Flat profiles for everyday doorway transitions
Beveled Threshold – One or both edges sloped for smoother transition
Hollywood Bevels – Extended, slanted edges ideal for wheelchair accessibility
Shower Threshold – Designed to block water ingress in wet zones
Custom Threshold – Cut-to-size and grooved options for specific project needs
Granite Thresholds
Granite thresholds are the ultimate blend of strength and elegance. Known for their durability, stain resistance, and ability to withstand heavy foot traffic, granite thresholds are ideal for both residential and commercial projects. Whether used in entryways, wet areas, or outdoor transitions, their natural speckled beauty and resilience ensure a lifetime of performance with minimal maintenance.
Quartz Stone Slab Thresholds
Quartz thresholds deliver contemporary aesthetics with practical performance. Manufactured from engineered quartz slabs, these thresholds are non-porous, consistent in color, and exceptionally resistant to moisture and stains. Perfect for bathrooms, kitchens, and sleek interiors, quartz thresholds bring minimalist design and high utility to everyday spaces.
Marble & Engineered Marble Thresholds
Marble thresholds add a touch of timeless luxury to any interior. Natural marble brings soft veining and unique character, while engineered marble offers uniformity, affordability, and ease of maintenance. Together, they provide a wide palette of aesthetic options—from traditional elegance to modern simplicity—suitable for door transitions, shower entries, and upscale design projects.
Design a seamless and elegant transition between different floor finishes with our premium thresholds. Featuring robust natural stone and engineered options, each threshold is precision-cut and polished for both beauty and long-term performance. Whether it’s black granite, Botticino marble, or white cultured marble, you’ll find options to match every design aesthetic.
