With degrees in both business administration and software engineering, Julian Secomb is an unlikely cabinetmaker. Yet he's spent over a decade earning his living by building furniture.

One of Secomb's gigs was building cabinetry into private jets for Bombardier. That acquainted him with the challenges of building in tight spaces. As #vanlife took off, Secomb then transitioned into kitting out vans, founding his company, Tetravan.

Vans outfitted for living often use similar interior solutions, but there was one that Secomb found persistently lacking across multiple designs: "They almost never had an optimal shower setup," he writes. "Most vans have a hose that is accessed via the rear door. This means standing outside in the mud, sand or snow to take a shower with limited privacy. The other option is a bulky shower enclosure that takes up valuable space in the van and feels claustrophobic. Neither of these are great solutions."

Secomb looked at the problem: A fixed shower requires a shower pan, which takes up valuable floorspace. What if he could make the pan, and for that matter the entire enclosure, disappear when not needed?

His solution is the Tetravan Folding Shower:

"The Tetravan Shower offers a full showering experience in your van, trailer or RV while using virtually no extra living space. To use it, fold down the shower pan and attach the included magnetic shower curtain. Setting up your shower takes under a minute. After you're done showering, the shower folds up and out of the way."

The steel pan is powder-coated for grip, and features a patented drain design that funnels water into a 2" trough, in case you're parked on uneven terrain.

The shower is designed to be installed beneath the sleeping platform, as shown here in Tetravan's turnkey trailer design. The plumbing and hot water heater are stowed in the storage space beneath the platform.

Secomb reckons his design takes up "75% less space than a solid shower enclosure" while providing a full-sized shower experience.

The Tetravan Folding Shower is made in the U.S.A. and sells for $1,850.
