Whats under your feet?

The Solid Start Beneath Every Forever Tiny Home

Discover how Forever Tiny Homes builds rock-solid subfloors with moisture-resistant materials and high-performance insulation—crafted for durability, comfort, and mobility.

What Makes a Great Subfloor?

At Forever Tiny Homes, we believe the best homes start from the bottom up. That’s why we treat subfloor construction as a critical phase of every build—not an afterthought.

Whether your tiny home will be parked permanently or moved cross-country, your subfloor is the foundation that supports everything above it: insulation, flooring, furniture, and you. So, we build ours to stand the test of time and travel.

Craftsmanship You Can Count On

Each Forever Tiny Home starts with a custom steel trailer. From there, we build a strong framed floor system using engineered wood sheathing and high-performance materials. The photo above shows a completed subfloor sealed and ready to receive framing—clean, tight, and built to spec.

Moisture Resistance from the Inside Out

Moisture can be a silent enemy in any home, especially mobile ones. We take this seriously. Our subfloor cavity is spray-foamed with closed-cell insulation, which acts as both a thermal and moisture barrier. Then we wrap and seal the entire undercarriage with a heavy-duty vapor barrier, protecting it from road debris, rain, and humidity.

Thermal Efficiency That Works All Year Long

Our insulation approach helps reduce energy costs and makes your home more comfortable in any climate. Closed-cell foam fills every cavity snugly, helping keep warm air in during winter and hot air out in summer.
