7 Easy Steps To Build A Home Theater Riser:

After you have completed making the home theater, all your friends and relatives will pay a visit there. So, we have to make the home theater riser just like a professional.

Here are some sure steps to make a home theater riser like a professional:

Step 1- Get Prepared:

The first step of making a home theater riser is getting prepared for the job. By getting prepared I mean to get all the tools and materials ready and within your reach. You will need the following tools for the job:

  • Miter Saw
  • Drill Machine
  • Circular Saw
  • Speed Square
  • Surface Measuring Level

You will also need the following materials too. Make sure to buy them in the exact size and amount that I have mentioned here: 

Wood Screws3” Size, Around 30 Pieces
LumberUntreated, 2 Feet x 8 Feet In Size
LumberTreated, 2 Feet x 6 Feet In Size
InsulationOld Foams, As Much Required
OSB SubfloorDimension: ¾” x 48” x 96”
AdhesivesRecommended For OSB Subfloor

Step 2- Build The Base:

The first step of building the home theater riser is to build the base of the riser. Using the treated 2 feet x 6 feet lumbers and 3-inches  screws, make two boxes as the base.

We are using treated lumber because it will be in contact with the concrete floor. Otherwise, untreated lumbers would rot, being affected by the concrete. Each of the two boxes should be 16 inches deep.

Step 3- Set The Base:

Now, place the boxes parallelly on the floor. Their back and sides should be in contact with walls. These boxes will act as the beams of the deck. So keep them as close as possible. If you intend to build a bigger home theater rise, you have to make extra boxes.

Then secure the boxes with the wall studs using the 3 inches wood screws and the drill machine. Install a blocking where you want the step to be. 

Step 4- Build The Joists:

At this point, you will build and set the joists for the home theater riser. Use the untreated 2 feet x 8 feet lumbers as the joists. Set the lumbers 16 inches apart from each other on 2 x 4 rim boards. Use the 3-inches screws for this.

Now put the joists along with the rim boards over the base boxes. Secure them with screws with the base or the wall studs. You need to keep open a 2-feet wide area on the corner that you chose for a step. Cut the rim joist 14 inches short in that area to make the step.

Step 5- Fill Up The Hollow Boxes:

If you leave the inside of the base empty, stepping on the riser will sound a lot. It will be a sure spoiler for the movie. 

The solution is filling up the hollow space of the base of the riser with insulating foams. Fill all the spaces under the joist with plenty of foams.

Step 6- Attach The Subfloor:

Now you have to install the subfloor OSB board on top of the joists. First, cut the OSB board in a shape that covers half of the base. Cut another OSB board leaving space for the step. There should be no space between the two boards.

Using appropriate OSB adhesives, attach the board on the joists, and also use screws to settle them there. You can put another layer of OSB board on top of the first one to reduce vibration in the riser while walking on them.

Step- 7- Install Carpet:

To make the riser more noise-free, install a layer of carpet over it. Carpets reduce friction between shoes and the OSB floor. The result will be a noise-free seamless celebration of movies.
