Dreaming of a romantic, circular wedding arch but worried about the cost? You’re not alone. Many couples search for affordable, DIY alternatives that still look elegant and professional. And yes—you absolutely can make a round wedding arch out of plumbing pipe. Not only is it cost-effective and lightweight, but with the right design, it can rival high-end rentals. In this guide, we’ll walk you through everything you need to know to build your own stunning arch, safely and stylishly.
Why Use Plumbing Pipe for a Wedding Arch?
Before diving into construction, it’s worth understanding why plumbing pipe—especially PVC—is a popular choice among DIYers:
Affordability: A full round arch can cost $20–$50 in materials vs. $300+ for rentals (The Knot, 2024).
Lightweight & Portable: Easy to assemble, disassemble, and transport.
Weather-Resistant: PVC won’t rust or corrode, making it ideal for outdoor weddings.
Customizable Shape: With heat or specialized fittings, you can create true curves.
💡 Pro Tip: While “plumbing pipe” often refers to PVC in DIY circles, technically it can include ABS or even EMT conduit. For wedding decor, Schedule 40 PVC (1–1.5” diameter) is the go-to for balance of strength and flexibility.
(Note: PVC is a type of plastic piping widely used in construction. Learn more about its properties on Wikipedia.)
What Tools and Materials Do You Need?
Building a round arch isn’t just about pipe—you’ll need the right components for stability and aesthetics.
Materials List:
PVC pipes:
(4) 10-ft sections of 1.25” Schedule 40 PVC (for the curved top)
Sandbags or concrete-filled buckets (for anchoring)
Decor: Fabric, greenery, flowers, zip ties, floral tape
Tools:
Pipe cutter or hacksaw
Heat gun (for gentle bending, optional)
Measuring tape
Marker
⚠️ Safety Note: Never use CPVC or metal plumbing pipes intended for hot water or gas—these may contain harmful residues. Stick to new, clean PVC from a hardware store.
Step-by-Step: How to Build a Round Wedding Arch from PVC
Follow these precise steps to create a stable, photogenic arch.
Step 1: Design Your Arch Dimensions
A standard wedding arch is 7–8 ft tall and 5–6 ft wide. For a true round look, the height should roughly equal the width.
Recommended curve radius: 30–36 inches
Total pipe needed: ~40 linear feet for a 7-ft-tall round arch
Step 2: Create the Circular Top
Option A – Use Pre-Cut Segments: Cut your 10-ft pipes into 12–16” sections. Connect them with flexible PVC elbows or spring benders to form a semi-circle. This “polygon” method mimics a curve.
Option B – Heat-Bend PVC (Advanced):
Use a heat gun at 250–300°F
Rotate pipe evenly until pliable (≈2–3 minutes)
Bend over a large bucket or template
Cool with wet cloth to set shape
📌 Real Example: Bride Sarah from Texas built her arch using 14” segments and 8 elbows—her arch held 30 lbs of greenery and survived 15 mph winds.
Step 3: Assemble the Frame
Connect two curved halves to form a full circle (or semi-circle if open-back).
Attach vertical legs using 90° elbows.
Add tees at the base to extend “feet” outward—this prevents tipping.
Do NOT glue unless you plan to keep it forever. Friction-fit allows reuse.
Using old or recycled pipe: May have cracks or chemical residue.
Ignoring venue rules: Some parks ban PVC structures—always check permits.
FAQ Section
Q1: Is PVC pipe strong enough for a wedding arch?
Yes, when properly assembled and anchored. Schedule 40 PVC (1.25” diameter) can support moderate decor weight (20–30 lbs). Avoid hanging heavy chandeliers or dense wood elements.
Q2: Can I make a full circle (360°) arch with PVC?
Technically yes, but it’s structurally unstable without a support beam. Most couples build a semi-circular (180°) arch for the ceremony backdrop—it’s safer and just as photogenic.
Q3: How much does it cost to build a PVC wedding arch?
Typically $25–$60, depending on pipe length and fittings. Compare that to $300–$800 for rentals (per The Knot’s 2024 pricing survey).
Q4: Do I need to glue the PVC joints?
No—and it’s better not to. A friction-fit (no glue) arch is reusable, transportable, and easier to adjust. Only glue if it’s a permanent installation.
Q5: Can I use copper or metal plumbing pipes instead?
You can, but it’s not recommended. Metal pipes are heavier, harder to cut/bend, and can get hot in sunlight. PVC is safer and more DIY-friendly.
Q6: How long does assembly take?
With two people: 45–75 minutes. Pre-cut and label all pieces the day before to save time on the wedding morning.
Conclusion
So—can you make a round wedding arch out of plumbing pipe? Absolutely! With under $50, basic tools, and a few hours of work, you can create a custom, elegant arch that wows guests and looks flawless in photos. Plus, you’ll have it for future events or to resell.
