Stone Essentials. Made to Fit.

Plato Surfaces offers stone thresholds, shower curbs and other finishing pieces in natural marble, granite and engineered quartz. Each piece comes finished, and most products can also be cut to your exact size. In addition, every product page shows the stone, finish, edge and size options, with the price for each size.

Marble thresholds for every doorway

Our marble thresholds cover the joint where two floors meet, for example at a bathroom door or between two rooms. First, choose an eased edge, a single Hollywood edge with one sloped side, or a double Hollywood edge with slopes on both sides. A sloped edge also makes the step between two floor heights smoother. Then pick a polished or matte finish to match your floor tile.

Quartz shower curbs, seats and shelves

Finish the shower with quartz shower curbs, shower seats and niche shelves in the same stone. In the same way, wall caps, window sills and vanity backsplashes complete the room, so every edge matches.

Custom stone products cut to size

Need a size that is not listed? In that case, use our Build Your tools for thresholds, shower curbs, niche shelves and shower seats. Simply choose your stone, finish and edge, then enter your final size. As a result, you see your price before you order.

Order a sample before you buy

Not sure which color to pick for your stone thresholds or shower curb? Every product page has an Order Sample button, so you can see the stone in your own room first. After that, order the finished piece in the size you need.
