Indoor Slide Installation: How to Build a Tube Slide (5 Steps) By Cari | Published on August 16, 2025August 22, 2025 Thinking about adding an indoor slide to your home? An indoor slide installation can transform your space into a fun, one-of-a-kind feature for kids and adults alike. In this guide, we walk you through the five key steps of installing a tube slide, highlight safety tips, and share a checklist of supplies to make the process smooth from start to finish. Justin Orphal from Coldwater, OH documented his project from start to finish so you can see exactly what goes into an indoor slide installation. The accompanying video covers everything from preparing the entrance opening to securing the final supports, offering a clear roadmap for your own project. Step 1: Preparing the Slide Opening (00:14) Every successful indoor slide installation begins with proper preparation. The first step is measuring and cutting or leaving enough room for the entrance opening. Precision here is essential to ensure the Sidewinder fits securely and lines up perfectly with the entry point. Reinforcing the framing around the cutout adds stability and long-term durability. For this build, the entrance measured about 3 feet deep by nearly 5 feet wide due to the angle of the slide. Other tube slides may only require a space as small as 3 feet by 3 feet. Because dimensions can vary, always refer to your installation manual before cutting to confirm the exact amount of space needed for your specific slide. Remember: measure twice, cut once. Step 2: Assembling the Entrance Ring (00:44) The next step is to assemble the entrance ring, which frames the slide’s opening. This piece not only creates a clean, finished look but also provides essential support for the slide connection. For the Sidewinder, put the entrance ring together along with the 90 degree turn section to complete the first segment. To assemble, align the sections and fasten them securely to guarantee both safety and a professional appearance. Take your time here, ensuring that each section fits snugly before tightening. Pro Tip: Always use a washer on both sides of each bolt. This small detail adds strength, improves stability, and helps your entrance ring hold up to years of use. Step 3: Securing the Entrance Ring (01:06) After assembly, the entrance ring must be firmly anchored to solid framing. This step is crucial since the ring will endure repeated use as kids enter and exit the slide. Using bolts or heavy-duty screws ensures the ring remains stable and secure over time. For this build, the entire ring was fastened with GRK screws: one centered on each side and one in each of the four corners. This method distributes the load evenly, keeping the entrance ring tightly in place for both safety and long-term durability. Step 4: Connecting the 3’ Slide Sections (01:38) With the entrance secured, the next step is attaching the modular 3-foot slide sections. Each piece is designed to bolt together, gradually forming the full tube slide. Checking alignment throughout this process ensures a smooth, safe ride. When assembling each section, a helpful technique is to stand the section upright and loosely attach all the bolts on each side before tightening them down. This approach makes adjustments easier and helps the sections fit together seamlessly. Pro Tip: Have a second person hold the section steady while you align and bolt it to the previous piece. This extra set of hands keeps everything stable and ensures a tight, aligned connection between sections. Step 5: Adding Support and Optional Riser (02:00) To complete your indoor slide installation, proper support is essential. Slide support posts or framing help maintain the correct angle and ensure long-term stability. Without reinforcement, even a well-assembled slide can shift over time, so this step is critical for both safety and durability. For this build, the homeowner added extra lumber under the floor opening to reinforce the joints at the top of the slide. He also plans to run a horizontal brace on each side of the slide for added support. These reinforcements ensure the structure remains solid through years of use. Because this project involved a 9-foot slide installed in a basement with 10-foot ceilings, the height difference had to be addressed at the exit point. To solve this, a 12-inch riser platform was added. Alternatively, you could extend the slide with an additional 3-foot section, eliminating the need for a riser. Practice Sports offers optional support posts that attach directly to the side of the slide for extra stability. While these posts work well in many installations, they weren’t used here due to plans to enclose the slide. Instead, the installer secured the slide with 2×4 framing and L-brackets, attaching it to a nearby structural frame running parallel to the slide path. This approach provided both strength and compatibility with the enclosed design. Safety First: Adding a Landing Pad (03:28) Safety doesn’t stop with the build. Adding a landing mat at the bottom of the slide helps absorb impact and prevents slips on hard flooring. It’s a simple addition that makes a big difference in overall safety. Final Look at the Installed Slide (03:38) Once complete, step back and admire your hard work. See how your tube slide instantly becomes a focal point of the room, while delivering endless fun. Watch the video for a quick overview of the entire process and a first-hand look at the completed project. Final Thoughts on the Experience (03:59) An indoor slide installation may seem ambitious, but when broken into clear steps, it’s very achievable. With the right supplies, careful preparation, and attention to safety, you can create a unique feature that adds excitement and character to your home.
