How do I create a waterfall countertop? 


A waterfall countertop is a countertop that 'falls' off the edge of a set of cabinets, creating the appearance of a continuous surface that blends from the top surface down the side. This look can be achieved by setting a custom countertop to be taller than it is wide and placing it beside the cabinets.

To place the cabinets and set their dimensions

  1. Click Build> Cabinet> Base Cabinet then click once in plan to place a base cabinet.

  2. Using the Select Object  tool, select the cabinet and then click Open Object .

  3. In the Base Cabinet Specification dialog, set the Height, and Width for the cabinet then click OK.

    For the purposes of this article the following settings are used:

    • Height: 42"

    • Width: 30"

  4. With the cabinet still selected click the Copy/Paste  tool, then click the Sticky Mode tool.

  5. Click 5 times in the plan to place 5 copies of the cabinet, then switch back to the Select Objects  tool.

  6. Use the cabinets'  Move edit handle to move the them into place.

  7. Group select the three cabinets on the Breakfast Bar side of the island and then click Open Object

  8. In the Base Cabinet Specification dialog set the Depth to 12" and click OK

To add the custom countertop

  1. Select Build> Cabinet> Custom Countertop from the menu.

  2. Click and drag a rectangle over the top of your cabinets to place your countertop.

  3. Resize the countertop using either Temporary dimensions or Manual dimensions to set the correct size for this countertop.

    For this example a 1" overhang was added to the front and a 12" overhang was added for the Breakfast Bar.

    Note: The Countertop's thickness and height will be set based upon the cabinets the countertop is sitting on. It is helpful to note that if you were to open this Custom Countertop's Specification dialog, the Top Height of the countertop would show as 42 7/8" even though the Cabinet Specification says the cabinet is 42" tall. This is because the Cabinet Specification dialog measures from the Floor Finish by default and the Custom Countertop measures from the subfloor.

To create the waterfall panels

  1. Select Build> Cabinet> Custom Countertop from the menu.

  2. Click and drag a rectangle to create the waterfall panel.

  3. With the Select Objects  tool, select the countertop and resize it to match the depth of the island and the thickness of the countertop.

  4. Click and drag to move the panel into place beside the island.

  5. With the Select Objects  tool select the panel and then click Open Object .

  6. In the Custom Countertop Specification dialog, specify the Top height and thickness to match the island top and click OK.

    For this example, the following settings are used:

    • Remove the checkmark from Set Height From Cabinet.

    • Set the Top Height to 42 7/8".

    • Remove the checkmark from Set Thickness From Cabinet.

    • Set the Thickness to 42 7/8".

  7. With the waterfall panel still selected click Copy/Paste  and then click Reflect About Object .

  8. Move the cursor so the reflecting line is centered on one of the center cabinets and then click to create the reflected copy.

  9. The waterfall countertop will now display on both sides of this kitchen island.
