Video: How to Use Foam Forms to Shape Your Countertops
Using foam forms
Custom-shaped concrete countertops require you to make special forms, which you usually won't be able to reuse for other projects. Foam allows you to easily cut contours of any shape, yet is economical enough for one-time-use jobs. Watch countertop designer Fu-Tung Cheng show you how to make foam forms using a simple mat knife and double-stick tape.
Unlike a slab of granite or predetermined squares of ceramic tile, concrete allows you to form
virtually any countertop shape imaginable. This is often a big selling point for concrete, because you can offer your clients longer spans, curves and other distinctive shapes and sizes that would be impossible to create with other countertop materials. You can also custom fit a concrete countertop to accommodate tight spaces or nonstandard layouts. See these examples of how countertop makers used shape to enhance their designs.

Center of Attention Designed to be a focal point in an ultra-modern house, this black concrete island resembles a ship or even a giant surfboard. "To understand the shape," says maker Mike Karmody of Stone Soup Concrete, "you have to imagine an oval
elliptical cone and you top it and flatten it then push it forward so
you have a void where you can put cabinets." See more photos of this project.
Cantilevered Snack Bar How do you fit a snack bar for two into a tiny kitchen? With concrete, the solution was easy: Cantilever it off the island and flair out the ends to accommodate seating and eating.
Oval Island Shaped like an oval racetrack, this kitchen island also features a striking 6-inch drop edge, something that could only be achieved with
cast concrete. Learn how it was made.
Double-Decker Kitchen Island
To save space for clients who wanted an 11-foot dining bar plus a kitchen island with a built-in sink, David Eerdmans of Nobel Concrete cast this countertop in two levels to combine both functions, and incorporated curves to reduce the span. Read more about this project.
Comma-ShapedCountertop Punctuate a poolside with a comma-shaped countertop. Outdoor spaces put fewer restrictions on countertop size and shape, allowing you to be more daring.
Going Full Circle
For those who want to show off their cooking skills, a round countertop provides the optimum seating arrangement, while making the cook the center of attention.
