    What is a Marble Threshold?

    A marble threshold is a strip of marble used to separate different flooring surfaces from one area to another such as a transition from a bathroom to bedroom. Marble thresholds are also known as marble saddles or transition thresholds. There are 2 main reasons to install marble threshold at a flooring project. For bathrooms or wet areas, marble thresholds are installed as water barriers. Marble thresholds block any water spill to flow to other flooring surfaces by creating a ½” to ¼” high raise at doors. Marble thresholds also provide a safe transition between floors with different levels such as tile to carpet, marble tile to wood flooring and so forth.

    How Do I Determine the Design of Marble Threshold I need?

    A marble threshold will usually have beveled edges to provide a safe edge for foot traffic. The bevel can either have one or two long top edges to provide a safe and polished finish, depending on the project type. If the threshold is used as an end piece to a floor, the threshold should have one long side beveled. However, if the threshold is used as a transition or separation piece, two long sides need to be beveled. There are 2 types of bevels on prefabricated marble thresholds.

    A standard bevel threshold is a threshold with 1/4” bevel, just to provide an eased edge. See drawings.

    Hollywood bevel threshold (aka handicapped bevel) is a larger bevel (1” – 1 3/8”). The bevel looks like a small ramp. Wheelchair access is made easy with the help of this little ramp which makes them a suitable and common option in commercial and multifamily projects.

    What Type of Marble Thresholds for What Type of Project

    Hospitality industry or multifamily projects such as hotels, restaurants and resorts usually finishes their bathrooms with 4 inch wide thresholds. Therefore, 4″ wide thresholds are also called hotel thresholds.

    All residential projects with hard surfaces such as ceramic, porcelain tiles or stone tiles will require a marble threshold, especially for main and bathroom entries.

    Type of Marbles Used for Marble Thresholds

    Thresholds are blends of two different materials of different areas. The natural stone used for the threshold will commonly be a matching color to either or both of the flooring materials. We have 5 standard stones we carry in stock for immediate delivery. Travertine, Crema Marfil Sahara (similar and replaces Botticino Marble), White Carrara (similar and replaces Bianco Carrara, Carbonia ,Alabama White, Georgia White Marble), Absolute Black Granite and Pure White Thazoz (similar and replaces Thassos Marble) are the preferred stones of designers and project owners to match flooring items due to their natural and neutral looks. We offer pre-fabricated thresholds for these materials which are ready for shipping. If your project requires a custom natural stone, we will meet your requirements.

    Dimensions of a Marble Threshold

    Doors have different standard sizes in width and length. Therefore, the thresholds need to be matching the door opening. In some US States, 2”x36” is the most common size with a simple 1/4″ bevel. However, in other states, the standard width is mostly 4” or 4 1/2″, 5″ or 6”. Hotel projects mostly use 4″ thresholds. The thicknesses of the thresholds are usually 3/8”, 1/2″, 5/8″ or 3/4″ and changes with the width. The standard opening of a door usually is 36”. That is why the length of a threshold would be 36″. In some special cases, for larger doors, longer thresholds are available such as 48” or 60”.

    Thresholds Packaging

    Thresholds are packaged in strong wood crates, durable for stacking and nationwide shipping. A polyurethane sheet separates thresholds individually to prevent them from scratching during handling and transportation. Poly-straps on crates increase the durability of the crates. These standard size stackable pallets result in significant savings on warehouse space and shipping costs.
