In this episode of our Toyota HiAce campervan conversion, we complete one of the most satisfying milestones of the entire build—installing the subfloor, timber ceiling and finished vinyl flooring.

With the insulation, wiring and wall panels complete, it's time to transform the van from a construction project into a space that genuinely feels like a home. Along the way, we explain the reasoning behind each step, the materials we chose, and the little details that make a huge difference to the finished result.

As always, we also share the mistakes, debates and lessons we learned so you can avoid making the same ones in your own build.

In this episode, you'll learn:

• How we prepared and installed the subfloor

• Why we install the walls before the ceiling

• Choosing and finishing tongue-and-groove pine ceiling boards

• Tips for achieving a clean ceiling installation

• Installing floating vinyl flooring in a campervan

• How we waterproofed and sealed the finished floor

• The small details that help create a professional-quality finish

Whether you're converting a Toyota HiAce or another campervan, this episode will give you practical ideas for creating a durable, great-looking interior that will stand up to years of travel.
