Caravan Renovation Guide and Products

Renovating, Retro-fitting or Building a Caravan using SJRV caravan parts and accessories

There’s nothing quite like the satisfaction of taking an old, tired caravan and bringing it back to life. Maybe it’s a faded 1970s tourer that’s seen better days, or a half-finished project that’s been sitting in the shed for years. Whatever you’re working with, the journey from stripped shell to fully functional caravan is one of the most rewarding experiences you can take on.

At VanDIY, we understand what it takes to transform a caravan from bare bones into a self-contained home on wheels. Whether you’re renovating, retro-fitting, or building from scratch, our SJRV range of caravan parts and accessories covers every stage — from the outside in.

We’ll start from the exterior, where protection, ventilation, and design all come together to form the foundation of your build.

Start with the Exterior – Building the Foundation

Windows – Flat Acrylic Hinged Windows with Built-in Screens and Blinds

Windows are one of the defining features of a caravan. They set the tone for the entire build — how it looks, how much light it lets in, and how comfortable it feels inside. The right windows make the difference between a dated, draughty caravan and a clean, modern space that feels like home.

At VanDIY, we stock a complete range of SJRV flat acrylic hinged caravan windows, ideal for restorations and new builds alike. These aren’t sliding windows — they’re hinged, which makes them lighter, cleaner, and better sealed against the elements.

Shop Windows: https://vandiy.com.au/collections/caravan-windows-with-screens

Why These Windows Stand Out

  • Flat Acrylic Construction: Lightweight yet durable, with UV-stable panels that resist fading and crazing — ideal for long-term Australian conditions.
  • Bottom-Hinged Design: Provides controlled airflow and keeps out rain while open. Perfect for both summer ventilation and winter protection.
  • Integrated Flyscreen and Blind System: The dual cassette gives instant control — pull down the blind for privacy or the flyscreen for airflow.
  • Streamlined Finish: The flush-mount design eliminates bulky profiles and gives a modern aesthetic that suits both classic vans and contemporary builds.
  • Internal Clamping Frame: Ensures a watertight seal for 25–40 mm wall thicknesses, reducing the need for screws through the outer frame.

Measurement and Fitment

  • All SJRV window sizes are listed as Height × Width, which refer to the cut-out (aperture) size in the caravan wall.
  • The overall frame is approximately 30 mm larger than the cut-out dimensions.
  • When cutting or enlarging an opening, allow an extra 2 mm of clearance both vertically and horizontally for easy fitting and thermal movement.
  • Apply a continuous bead of flexible caravan-rated sealant (see Sika’s Caravan & Motorhome Guide) around the flange before installing.
  • Tighten fixing screws evenly to avoid twisting the frame and ensure even compression on the seal.

These SJRV hinged windows are practical, attractive, and simple to install — the perfect start to modernising your van’s appearance and comfort.

Access Doors and Hatches – Smart Utility and Easy Access

Every caravan renovation needs functional access points — not just for storage, but for the hidden systems that make your van work. Think battery compartments, toilet cassettes, water tanks, and under-bed storage.

VanDIY supplies a wide range of SJRV access doors and hatches designed to fit almost any purpose while maintaining a dustproof, watertight seal.

Shop Hatches: https://vandiy.com.au/collections/caravan-access-hatches-van-diy-australia-wide-delivery

Common Hatch Locations

  • Storage Hatches: Add access to under-bed or under-seat storage areas so you can reach tools, hoses, or camping gear without unpacking the interior.
  • Utility Hatches: Perfect for electrical enclosures, battery bays, or inverter compartments that need both airflow and access.
  • Toilet Cassette Doors: Installed on the outer wall beside the bathroom to allow easy removal and cleaning of portable waste cassettes.
  • Gas Locker or Service Doors: Provide access to gas bottle compartments while maintaining ventilation and compliance.

Installation Guidance

  • Plan Early: Cutouts should be positioned before final wiring, plumbing, or insulation.
  • Surface Prep: Choose a flat mounting surface to ensure the hatch compresses evenly against its gasket.
  • Sealing: Apply Sika’s caravan-grade flexible sealant to the mounting surface before fastening. Avoid silicone-based products that can peel over time.
  • Fastening: Tighten fixings progressively and check seal compression.
  • Security: SJRV hatches feature secure locks — ideal for storing tools, cables, and equipment.

Durable, UV-stable, and simple to install, these hatches are built for real-world conditions and professional results.

Fitting New Doors – Exterior Entry & Utility Access

Shop Doors: https://vandiy.com.au/collections/caravan-pop-top-and-motorhome-doors

A caravan door is more than just an entry point — it’s about security, insulation, and presentation. Installing a new door instantly modernises an older van and ensures dust and water stay out.

Key Considerations for Door Installation

  • Measure the Cutout, Not the Frame: Caravan doors are specified by their aperture (height × width). Check wall thickness before ordering to ensure compatibility.
  • Support and Framing: Reinforce around the door cutout to prevent flexing and to support hinges properly.
  • Sealant: Apply a continuous bead of Sika’s flexible sealant to avoid future leaks.
  • Alignment and Fit: The door should close smoothly, compressing evenly along the seals — no gaps, no over-tightening.
  • Threshold Drainage: Angle the sill outward or use a drip edge to shed water away from the wall.

A properly fitted door provides better insulation, dust resistance, and sound reduction — critical for both comfort and durability.

Caravan Entry Steps – Manual or Electric for Easy Access

Shop Steps: https://vandiy.com.au/collections/caravan-rv-steps-manual-automatic-van-diy-australia-wide-shipping

Getting in and out of your van safely is one of those details that’s often overlooked until it becomes a hassle. VanDIY’s SJRV caravan steps make access easy and reliable — available in both manual and electric operation.

Step Options

  • Manual Steps: Simple and durable — fold in or out by hand, with no electrical connection required.
  • Electric Steps: Controlled by switch or linked to the caravan door or ignition circuit, automatically retracting when closed.
  • Single and Double Models: Choose a single step for low-floor caravans or a double step for high chassis motorhomes.

Installation Notes

  • Mount steps securely to the caravan chassis or frame with rated bolts.
  • Check for adequate clearance both when extended and retracted.
  • Lubricate pivot joints regularly to maintain smooth operation.
  • Seal all mounting points and wiring entries using Sika’s Caravan & Motorhome Sealant to prevent corrosion.

Whether you’re stepping into a retro van or a new build, upgrading your steps adds safety, comfort, and ease to every trip.

Outdoor Serving & Prep Area – Fold-Out Wall Table with LED Light

Shop Fold-Out Tables: https://vandiy.com.au/collections/caravan-fold-out-table-with-led-light

A fold-out table mounted to the caravan exterior adds instant practicality. It becomes a prep bench for cooking, a place to serve drinks, or even a compact workstation. VanDIY’s SJRV fold-out wall tables are designed for durability, simplicity, and everyday use — with built-in LED lighting to keep the space functional at night.

Why It’s Worth Adding

  • Instant Workspace: Create an outdoor prep area without taking up interior space.
  • Integrated Lighting: The LED strip illuminates your workspace for evening cooking or entertaining.
  • Space Efficient: Folds completely flat against the wall when not in use.
  • Durability: Built to withstand outdoor exposure, vibration, and UV.

Installation & Setup

  • Mount the table onto a strong, flat wall surface.
  • Apply a bead of Sika caravan sealant behind all mounting points to prevent water ingress.
  • Connect the LED light to your 12 V circuit, ideally switched near the table location.
  • Install under an awning or sheltered section for best usability.

Once fitted, you’ll wonder how you ever travelled without one — it’s one of the simplest and most useful exterior upgrades you can make.

Roof Vents & Airflow Systems

Airflow is one of the most critical factors in keeping your caravan comfortable, dry, and free of condensation. Without proper ventilation, humidity from cooking and showering can build up quickly, leading to mould, swelling in timber cabinetry, and a musty smell that’s hard to remove.

That’s why every quality build should include one or more SJRV roof extraction fans — purpose-built to remove stale, moist air and draw in fresh air when needed.

Shop Roof Fans: https://vandiy.com.au/collections/caravan-roof-extraction-fans

The SJRV AirPlus Range

Why Roof Vents Matter

  • Condensation Control: Prevent moisture build-up in bathrooms and kitchens.
  • Temperature Regulation: Expel heat that collects under the roof during the day.
  • Comfort: Constant, quiet airflow keeps the interior feeling fresh even on still nights.
  • Energy Efficiency: Helps your air conditioner run more efficiently by reducing trapped heat.

Installation Tips

  • Fit the vent directly above moisture-producing areas — shower, toilet, or cooking zone.
  • Use Sika’s caravan-grade flexible sealant to bond and waterproof the flange.
  • Wire the fan through a fused 12 V circuit with a simple roof switch or remote receiver.
  • Pair vents with openable windows for optimal cross-flow ventilation.

Good ventilation isn’t optional — it’s a vital part of every successful renovation and one of the simplest ways to protect your investment from long-term damage.

Exterior Climate Comfort – Fitting a Caravan Air Conditioner

Shop Air Conditioners: https://vandiy.com.au/collections/air-conditioners

While roof fans manage airflow, sometimes you need true climate control. For that, nothing beats a dedicated caravan air conditioner. The Global Heritage series, available from VanDIY in both 2500 W and 3500 W models, provides reliable reverse-cycle heating and cooling in a compact rooftop design.

Why Add One

  • Comfort in All Conditions: Cool in summer, warm in winter — both models include reverse-cycle functionality.
  • Low-Profile Design: Streamlined for minimal roof drag and noise.
  • Quiet Operation: Sleep comfortably with reduced vibration and sound levels.
  • Reliable Power: Designed for 240 V mains power, ideal for caravan parks or generator use.

Models Available

  • Global Heritage 2500 W: Perfect for smaller caravans or single-room layouts.
  • Global Heritage 3500 W: Higher output for larger vans or hotter climates.

Usage Tips

  • Air conditioners draw significant power — they’re best used when connected to mains or a large generator.
  • Clean filters regularly for optimal airflow.
  • Seal the roof aperture using Sika’s caravan and motorhome sealant for leak-free operation.

Move Inside – The Heart of Your Caravan

Hot Water Systems – Reliable Comfort Inside

Shop Hot Water System: https://vandiy.com.au/products/global-heritage-28l-gas-electric-hot-water-system-van-diy

When renovating or building a caravan, few upgrades improve daily comfort more than having hot water on demand. The Global Heritage 28 L Gas & Electric Hot Water System offers the best of both worlds — reliable off-grid gas heating and efficient electric heating when you’re plugged in at a park.

Key Advantages

  • Dual Fuel Operation: Choose between LPG gas or 240 V electric.
  • Compact Design: Fits neatly in service bays; requires only 325 × 325 mm cut-out.
  • Lightweight: Approx. 12.2 kg, gentle on your GVM.
  • Large 28 L capacity: Comfortable supply for daily use.
  • Durable Construction: Corrosion-resistant casing designed for mobile use.

Installation Considerations

  • Position close to the bathroom or kitchen to reduce heat loss through plumbing.
  • Provide exterior venting for gas mode operation.
  • Seal all panel fixings with Sika’s sealant to prevent water ingress.
  • Connect drain hoses to a safe discharge point beneath the van.

Usage Example

  • On-Grid: Run on 240 V mains to save gas and take longer showers.
  • Off-Grid: Switch to LPG mode for full independence.

Interior Comfort – A Simple Fan That Makes All the Difference

Shop VoltSafe Fan: https://vandiy.com.au/products/rv-volt-safe-fan-12v-caravan-motorhomes-and-tiny-homes-12-24v-input

When the temperature rises but you’re camping off-grid, an efficient 12 V fan can make all the difference. The SJRV VoltSafe Fan is built precisely for that — strong airflow, minimal noise, and extremely low power draw.

Key Features

  • Dual Voltage: Operates on both 12 V and 24 V systems.
  • Low Power Consumption: Draws about 0.12 A on low speed.
  • Quiet Airflow: Circulates up to ~238 m³/h with minimal vibration.
  • Timer Function: 3, 6, or 9-hour automatic shutoff.
  • Compact Build: Mounts easily beside the bed, kitchen, or lounge.

Installation Tips

  • Connect directly to your van’s 12 V distribution system or dedicated fan circuit.
  • Mount near the sleeping area for maximum comfort.
  • Combine with a roof vent to maintain continuous air exchange overnight.

Laundry On The Move – Wash Your Clothes While Off-Grid

Shop Washing Machine: https://vandiy.com.au/products/caravan-rv-washing-machine-2-5kg-240-volt

One of the most underrated comforts of modern caravan life is being able to wash clothes anywhere. The SJRV 2.5 kg 240 V Caravan Washing Machine gives you that independence without taking up space or requiring complex plumbing.

Benefits

  • Compact and Lightweight: Ideal for ensuites or cupboards.
  • Simple to Operate: Straightforward wash and spin cycles.
  • Low Water Use: Efficient for small, frequent loads.
  • Quiet Operation: Balanced spin suitable for caravan floors.

Installation Notes

  • Secure the unit with brackets or straps to prevent movement.
  • Drain grey water into an external tank or approved outlet.
  • Best on 240 V mains; suitable via inverter when off-grid if sized appropriately.

Keeping Food & Drinks Cold – Choose the Right Fridge for Your Build

Your fridge is the heart of the caravan kitchen. VanDIY’s SJRV fridge/freezer range includes models for every type of traveller.

Shop Fridges:

Why Choose a Compressor Fridge

  • Maintains consistent cooling even in high ambient temperatures.
  • Runs directly on 12 V or 24 V DC — ideal for solar systems.
  • No gas required — simple, safe, reliable.
  • Quieter and more power-efficient than older 3-way systems.

Choosing the Right Size

  • 50 L: Compact setups, weekenders.
  • 85 L: Couples or small families on short trips.
  • 150 L: Extended travel or family touring.
  • 170 L: Full-time living and maximum storage.

Installation Advice

  • Allow ventilation space behind and above the fridge.
  • Pre-cool before loading to reduce power consumption.
  • Secure firmly with brackets to handle road vibration.
  • Use correct gauge cabling to minimise voltage drop.

Keeping Your Fridge Running at Optimum Temperature – Fridge Ventilation Matters

Shop Fridge Vents: https://vandiy.com.au/collections/caravan-and-rv-fridge-vents

Even the best fridge will struggle without proper ventilation. As compressors work, they generate heat — and if that heat can’t escape, your fridge runs longer, drains more power, and shortens its lifespan.

Vent Options

  • SJRV FV1000: Passive vent for smaller setups.
  • SJRV FV2000: Larger passive vent for improved air movement.
  • SJRV FV3000: Dual 12 V fans to actively extract hot air.

Installation

  • Install one vent low (air intake) and one vent high (hot air outlet) to create a chimney effect.
  • Seal cut-outs and frames with Sika’s sealant to prevent moisture ingress.
  • Wire the FV3000’s fans to a switch or thermostat for automatic operation.

Better ventilation equals better fridge performance — colder temps, less power use, longer compressor life.

Powering Your Caravan – Reliable Lithium Battery Systems

Shop Lithium Batteries: https://vandiy.com.au/collections/caravan-lithium-batteries

Modern caravans depend on stable, long-lasting power. SJRV lithium batteries, supplied by VanDIY, are built with heavy-duty metal cases and high-performance cells that deliver consistent energy for years.

Battery Options

  • 100 Ah: Compact setups — lights, fridge, and fans for weekends.
  • 200 Ah: Balanced capacity for extended touring with moderate inverter use.
  • 300 Ah: Heavy-duty power for long-term off-grid or high-current devices.

Advantages

  • True rated capacity with stable voltage under load.
  • Rigid metal housing protects against heat and vibration.
  • Long cycle life with integrated BMS protection.
  • High discharge capability for devices like coffee machines or induction cooktops (with suitable inverter).

Installation Guidance

  • Mount in a cool, ventilated area and secure against vibration.
  • Use correctly rated cabling and fuse protection.
  • Pair with lithium-compatible DC–DC and solar chargers.
  • Seal cable pass-throughs with Sika’s caravan sealant.

With up to double the usable power of AGM batteries and faster charging times, SJRV lithium batteries are the foundation of a modern, self-sufficient electrical system.

Caravan Toilets – Comfort and Convenience Wherever You Travel

Shop Toilets: https://vandiy.com.au/collections/caravan-portable-toilets

Caravan living is all about independence, and having a reliable toilet setup makes a huge difference on long trips. SJRV portable caravan toilets, available through VanDIY, combine ease of use with simple maintenance and solid construction.

Key Features

  • Lightweight, durable construction designed for mobile conditions.
  • Manual or pump-flush operation using minimal water.
  • Sealed waste cassette for odour-free performance.
  • Separate fresh and waste tanks (typically 10–15 L and 20 L).
  • Secure locking lid to prevent spills during travel.

Installation and Use

  • Position securely within the bathroom area or a dedicated bay.
  • Use approved caravan toilet chemicals to break down waste.
  • Empty and rinse tanks regularly; avoid harsh cleaners.
