DIY Wall Mounted Cat Tower With Shelf

So you want to build your cat an epic cat tower? Check out this do it yourself instruction manual for a wall mounted, 6 foot tall cat tree, complete with a carpeted a shelf on top. Materials cost about $100, which is quite a bit cheaper than buying a pre-built 6 foot cat tower, assuming the required tools are already handy.

Position this tower next to another cat tree or piece of furniture, such as a dresser or bookcase, for maximum catification.


Head to your local hardware store and pick up the following cat tree materials. You'll only need a few small pieces of wood in addition to the other materials. You might have some scrap wood lying around that will do the trick.

Tools for building a cat tree

1. Cut the PVC

Cut the PVC pipe to a 6 foot length. This can easily be modified for a taller or shorter cat tree. You'll need about 35 feet of Sisal Rope per foot of pipe.

2. Measure & cut interior wood stud

You're going to jam and screw two pieces of shaped wood into each end of the PVC. These wood studs are going to stabilize the top and bottom of your cat tower.

Measure the interior diameter of the PVC pipe. It should be about 3 inches.

Cut the 12 inch long 2 x 6 vertically so the piece matches the 3 inch interior of the PVC pipe.

  • Measuring to cut a piece of wood
  • Cutting a piece of wood vertically

2. Shape wood stud

Round both sides of the interior piece of wood to match the curvature of the inside of the pipe. This will be hidden so it doesn't have to look pretty.

  • Rasping a piece of wood to round the edges
  • A piece of wood to rounded on one side

3. Divide wood stud into two pieces

Chop the 12 inch shaped piece of wood in half into two 6 inch long pieces. One piece will go in the top of the PVC and one will go in the bottom.

4. Hammer each stud into the PVC's ends

Wedge the wood pieces into the top and bottom ends of the PVC pipe with a hammer, the fit should be tight. We'll be anchoring the foot and shelf to these.

If necessary, sand or rasp the sides facing out so they are flush with the PVC's ends.

  • Hammering wood into the end of a PVC pipe
  • A PVC pipe shimmed with wood

5. Anchor the studs to the PVC

Pre-drill two 1/16 inch holes into each stud, through the PVC pipe.

Insert two screws, through the PVC and into each of the studs. One on the top and one on the bottom of the pole.

  • Pre-drilling PVC mounting studs for cat tree
  • Screwing PVC to studs
  • PVC pipe with wood studs in the end

6. Cut and shape a wood wall brace

The cat tower is going to sit about two inches away from the wall. You'll want to brace it so it doesn't kick out. Cut the 2 x 2 wood dowel into a 2 inch long block. Then rasp one end so it is slightly concave and fits nicely around the pipe.

Rasping a small piece of wood

Attach a metal "L" bracket to the PVC pipe, anchoring it to the wood stud inside the pipe at the bottom.

Note: Only attach the "L" bracket to the PVC pipe for now, not the wood brace. I had to remove the wood block before wrapping the sisal (see step 12).

7. Shape the bottom foot

Trace the end of the PVC pipe onto the 1 x 4 inch piece of wood. Roughly saw out the circle. Then rasp it down into a fitted circular base. Polish the entire disc with sandpaper.

  • A circle traced on a piece of wood
  • Cutting a circular piece of wood with a hand saw
  • Rasping wood into a circle
  • Circular wood base
  • Sanding a circular wood base

8. Attach the sisal rope to the bottom of of the tree

Drill a hole through the PVC, perpendicular to the inner wood stud, at the very bottom of the pipe.

Thread the sisal rope through the hole and tie a knot on the inside end. This will secure the the rope to the base of the pole.

  • Drilling a hole in a PVC pipe for a cat tree
  • Threading rope through PVC for a cat tree

9. Attach the bottom

Pre-drill two 1/16 inch holes through the bottom base into the wood stud in the bottom of the PVC pipe.

Insert two screws through the wood base to secure it to the inner stud.

  • Pre-drilling holes to screw a bottom to PVC
  • Screwing a bottom disc to a PVC pipe

10. Wrap and glue

Wrap the PVC with the sisal rope. Applying hot glue between the plastic and rope about once every revolution.

  • Hot gluing sisal around PVC pipe for cat tree
  • Wrapping sisal around PVC pipe and hot gluing for cat tree
  • Hot gluing sisal to cat tree
  • Building a cat tower

11. Zip-tie the sisal segments

When a segment if sisal rope ends, zip-tie it to the next segment, about an inch before the ends meet. Add a good amount of hot glue where the rope segments join and continue to wrap.

12. Attach the wood wall brace

Screw the wood wall brace to the "L" bracket sticking out through the wrapped sisal.

13. Cut the rug

Measure and cut the carpet remnant or mat matching the dimensions of the shelf, 10 x 24 inches.

14. Attach the shelf to the tower

Two people is recommended for this step.

Position the shelf on top of the pole against the wall where it will be mounted. Pre-drill two 1/16 inch holes through the shelf and into the wood stud that has been anchored inside the top of the PVC pipe.

Insert two screws, through the shelf into the stud to secure the shelf to the pole. Just like you did for the bottom but through the top shelf instead.

Sorry, didn't get a photo of this step.

15. Install the shelf bracket

Draw a line at the height of the shelf. Locate a stud in the wall where you plan to anchor the tree (use a stud finder or knock on the wall).

Install the shelf bracket under the shelf, screwing into the stud in the wall with the 3 inch wood screws. Then attached the bracket to the shelf with the 1 inch wood screws.

16. Secure the shelf to the wall

Add an extra "L" bracket to the top of the shelf on the pole side. Then screw it into the shelf and the wall to keep the top of the pole from pulling away from the wall.

Screw another "L" bracket to connect the wood brace to the wall. The tree should now be securely anchored at the top and bottom.

  • Wall brace on a cat tower

15. Attach the carpet

Hot glue the carpet to the shelf. You can additionally attach it with industrial staples or small nails to secure carpet to the shelf, since cats will be pulling themselves up on it.

Hi! I made this for my cat, but substituted the plastic PVC with leftover cardboard rolls from my printers and used jute rope instead of sisal as it was cheaper. I have a longer shelf so I also made a cave in one end from flooring felt. She seems to like being hidden and there are holes she can peek through. I'm still working on some attachment issues as I have less tools available, but overall it's a great project! Thanks : )
