Cool Tree House Floor Ideas

By Kyle Schurman Created: May, 2021

When completing a build for a tree house for the kids, after focusing on making it structurally safe, consider adding a softer, colorful flooring to make the space more enjoyable for kids to use. A bare tree house floor typically consists of a weather treated plywood, which may have a rough exterior and an undesirable greenish tint.

Other materials will work better for the tree house floor, going over the plywood and eliminating the chance of splinters. Some of the most popular soft and durable floors will include:

  • Economy Foam Mats
  • Play Mats Foam Puzzle Tiles
  • Reversible Wood Grain Foam Tiles
  • Premium Foam Kids and Gym Mats
  • Rubber Flooring Rolls

What Are Some of the Most Colorful Tiles for a Tree House Floor?

EVA foam tiles are an excellent choice to install over plywood in the tree house. These tiles have a high level of durability, while also yielding cushioning and waterproof capabilities. They’ll survive temperature extremes.

Each tile will have an interlocking edge that resembles a jigsaw puzzle. Installation goes quickly and doesn’t require any special know-how or experience.

The Economy Foam Mats product is a good place to start, as it appears in black, blue, and gray colors. Create a random color pattern or a checkerboard, if desired.

Each tile measures 2x2 feet, so it only takes a limited number of tiles to cover a big space in a short amount of time. This mat’s puzzle edges fit tightly into the edges of an adjacent mat without the need for glue. At only 1/2 inches in thickness, the lightweight tiles (1 pound each) are easy to carry up into the tree house.



If your kids like the idea of creating wild color patterns in the floor for the tree house, the Play Mats Foam Puzzle Tiles product is going to fit these needs. These tiles ship in packs of four 2-by-2-foot tiles, each of which is a different color (red, blue, green, and yellow).

Installers can create almost any desired pattern in the floor with these colors, or they can stick with a random color layout. These mats measure 1/2 inch in thickness and weigh 1.25 pounds per mat.



For a more natural and classy look in the tree house, the Reversible Wood Grain Foam Tilescontain a faux wood grain pattern that resembles actual hardwood. The opposite side of the reversible foam tile contains a tan color with a thatch texture that resists showing scuffs.

Each 1/2-inch thick tile has a 2x2-foot measurement, so the layout goes quickly. A single tile weighs only 1.2 pounds, which simplifies installation.

These tiles appear in six different wood stain colors including:
  • Standard wood grain
  • Light wood grain
  • Dark wood grain
  • Brown wood grain
  • Deep brown wood grain
  • Gray wood grain



When kids want the widest range of bright colors for the foam flooring inside the tree house, count on the Premium Foam Kids and Gym Mats, which have more than a dozen different colors available, including yellow, pink, purple, red, and orange.

Each of these puzzle style tiles measures 5/8 inches in thickness, which gives them a bit more cushioning than what’s available in the other EVA foam tiles on the list. A single tile weighs only 1 pound and covers 4 square feet.

Can You Install Rubber Flooring in a Tree House?

The Rubber Flooring Rolls product is another option to go over the plywood flooring base in a tree house. Rubber can stand up to any weather, and it is extremely durable.

Kids who don’t want a basic black roll of rubber in the tree house will appreciate the wide range of color flecks embedded in these rolls, creating an interesting look in the flooring. Rolls are available with a single color fleck or flecks of more than one color.

Order a custom cut length of this rubber roll to cover the available space. Multiple thicknesses are available, ranging from 1/4 to 1/2 inches. In most cases, ¼ inch is plenty thick for this application. It’s also important to keep in mind that rubber flooring, while extremely durable, will weigh quite a bit more than foam flooring.

How Do You Install a Tree House Floor Inexpensively?

The materials listed above will create a cool tree house floor, while also allowing completion of the job inexpensively. Rubber and foam both provide coverage at a low cost per square foot.

An adult and a kid can work together to assemble the tiles or to install the rubber roll, creating a DIY installation option that saves money versus trying to hire a professional. This helps the tree house construction adventure stay within a tight budget plan.

When trying to fit the foam tiles or thin rubber roll up against the side of the tree house, just measure the available space and cut the flooring with a utility knife. These materials are durable, yet the installer can cut through them in a short amount of time with a sharp blade to create a tight fit.

As an added money saving feature, these materials are removable. By creating a temporary floor in the tree house, the installer can replace a single tile to repair a damaged section of the floor.
