DIY Campervan Conversion Kits | Furniture Modules to Kit Out a Van, Fast

Converting a van into a camper takes a lot of accomplished DIY skills.

You’ll need to be a carpenter, metalworker, electrician and plumber. At times you’ll wish you were a magician!

If you have all of these skills in abundance, a conversion might be relatively straight forward.

Not everyone knows how to build a camper van though.

If you don’t have any DIY skills, then buying a pre-loved camper is a great option.

You’ll need deep pockets to outsource the entire project to a custom van conversion company

If you don’t have the money for a custom build nor the skills to do it yourself, campervan conversion kits can help save the day.

Instead of building everything from scratch, a kit already includes the major components. All you have to do is install it.

Van conversion kits vary in quality, components and cost. 

Some are simple packages of components, not specific to any vehicle model. 

Others are complete furniture modules, designed for the most common vans likes Sprinters, Promasters and Fords.

In this post, we’ll show you 8 DIY campervan conversion kits.

We’ve included the popular pre-packed furniture modules as well as kits to install all the amenities like plumbing, electrics and bathrooms.

Easy fit furniture kits

Building beds and furniture into a camper conversion demands a level of carpentry skills.

Our own Sprinter van conversion is built around an aluminium frame so we relied on our (Graham’s) metal working skills.

But if you don’t know a dovetail from a miter or one end of a claw hammer from a spirit level, building a camper interior is a tall ask.

That’s where furniture conversion kits providing modular interiors come into their own.

There’s several types of kit on the market and many companies with products and services available. 

Researching this post, we found it a pain trying to figure out and compare what each includes (and more specifically, doesn’t include). 

We’ve tried to summarise it here.

Complete modular conversion kits

Some companies provide complete conversion kits, often designed for specific vehicle models.

The high end companies are virtually offering a custom build, but with predesigned layouts to choose from.

Others offer pre configured modules you can mix ’n’ match, a bit like Ikea wardrobe systems.

Conversion kits are available for small vans as well as larger RVs

Some companies will post your flat pack interior while others insist you bring the van to them for installation.

Few, if any, offer a bathroom module and water tanks aren’t usually underslung either.

Choices often include optional extras like a fridge, cooker, campervan ovens or roof vent

If you’re considering going down this route with your build, have a list of question to ask the companies before making the final decision. 

We suggest you read our complete guide to converting a camper first.

Even if outsourcing the job, this will help you ask the right questions before handing over any hard earned cash.

Ask questions like:

  • If insulation or heating is included, is it enough to keep you warm in the conditions you will travel? 
  • What materials are used in the build? We recommend steering clear of flimsy materials and fittings. A few hundred kilometres on the road, especially tracks will make screws and bolts loosen with ease
  • Is the electrical system sized to meet your needs? Use our electrical calculators to work out what size setup you need.
  • Can you speak with previous customers for references?
  • Check out guarantees and warranties offered.

Campervan Electrical Kit

Installing a well sized, fit for purpose electrical system in a camper is one of the most complex and important elements of the entire build.

We have loads of electrical articles to guide your through the entire process, from sizing calculators to installation guides.

These are the key components you’ll need. They’re perfectly sized for a couple living in a van full time, off grid and through all seasons.

This kit provides solar electricity and charges the leisure batteries from the camper’s engine as you drive too.

Mains Hook Up Kit

Winterizing the camper electrical system is important too to save the expensive batteries from freezing

Though a well sized solar system means you can live off grid, it’s a luxury to have the opportunity to top up the batteries from mains power.

Adding a hook up kit is low cost and doesn’t take up much inside space, so we recommend including this in your conversion.

Heating & Ventilation Pack

Condensation on window

Good ventilation will help stop condensation in a van, critical to keep rust and mould out of the camper. An electric roof vent is best.

heating system in the camper forms part of the solution to condensation but as importantly, helps keep you comfortable and toasty, even in the coldest of winters.

We recommend a good diesel heater for winter RV living. They come in gasoline versions too if you vehicle doesn’t run on diesel.

If you don’t need heating year round, a good quality portable heater will serve you will on chilly summer evenings.

Plumbing & Bathroom Kit

DIY Campervan Conversion Kits

A fully plumbed camper van water system offers the opportunity for hot & cold water, a kitchen sink and a shower.

How much of this you need in your camper is down to how you’ll use the van once it’s built.

Living in a van full time is much easier and has more freedom with all onboard amenities installed. 

But if you only plan to use it for camping weekends a few times a year or maybe a week here and there, depending mostly on campsites, these are luxuries you could easily live without.

We’ve included below the major components for installing a water system.

** Read our post on campervan showers for more information about the options for getting hot water. They make a difference to the shower components needed.

DIY Camper Kitchen Kit

Campervan kitchen

The heart of many homes and it’s no different in a camper. 

Whether you have a van big enough to cook inside or a camper to cook beside, a well equipped kitchen makes for a happy camper.

Here’s the major components of a DIY camper kitchen we feel make a massive difference to van life.

Accessories & Interiors Fittings

Kitting out a van so you get everything you want and making the build as straightforward as possible, takes forward planning.

It’s easy to overlook some accessories and fittings at the outset. The major components of the furniture, plumbing and electric will likely take most of your attention.

But there’s a few other items to consider in the early stages of the build. 

If you plan on fitting an awning, do it early so you don’t have to rip out the insulation and panelling.

Adding swivel seats may be a great way or making the most of the space, so affect the floor plans.

Here’s the components to consider before you get too far into the build. You don’t need them all by any stretch but it’s easy to build into the plans than to retrospectively fit.

Safety & Security

Campervan conversion kits help build a van fast

After all the effort, time and money spent on the conversion, keeping it secure and the occupants safe is a major consideration.

Try to avoid this being an after thought though. We added extra security bolts to our van before we even started the interior fit out.

And adding a safe and building the furniture around it add another layer of security too.

And most of all, have fun! A van conversion is one of the most rewarding things you can do.
