An indoor shower is one of the most debated features in van conversion planning — genuinely useful for some travel styles, genuinely wasted space for others. Here's how to actually decide.

What an Indoor Shower Actually Costs You

  • Floor space: even a compact wet-bath shower stall needs roughly 30-36" x 30-36" of floor space — on a smaller van (144"/136" wheelbase), that's a meaningful chunk of an already tight layout.
  • Water capacity: showering draws down fresh water and fills grey water tanks faster than sink use alone — sizing both tanks needs to account for actual shower frequency, not just baseline daily usage.
  • Weight: the shower stall/pan itself, plus the water system capacity needed to support it, adds real weight to a build (see our weight distribution guide).
  • Ventilation requirement: an indoor shower without a dedicated vent fan leads to serious condensation and mold risk given how much moisture a shower releases into an enclosed space — this isn't optional if you install one.

Wet Bath vs Dedicated Shower Stall

A wet bath combines the shower and toilet in one small waterproof room — the whole room gets wet and drains, similar to a small RV bathroom. This is more space-efficient than separate shower and toilet areas but means the whole room needs to dry out between uses.

A dedicated shower stall (sometimes with a fold-out or pull-across curtain) keeps the shower separate from other functions, sometimes doubling as a wet-gear rinse area or extra standing space when not in use as a shower.

When Indoor Showers Make Sense

  • Full-time living where daily hygiene routine matters more than in occasional-trip use, especially in weather or locations where outdoor/public showers aren't practical.
  • Cold climate travel where an outdoor shower simply isn't usable much of the year.
  • Privacy-sensitive situations — stealth camping in urban areas where an outdoor shower isn't an option.

When It's Often Skip-Worthy

  • Weekend/trip-based use where gym showers, campground facilities, or a simple outdoor solar shower cover the need without permanently sacrificing floor space.
  • Smaller wheelbase vans where the layout tradeoff (losing kitchen counter, storage, or bed comfort) outweighs shower convenience.
  • Budget-constrained builds — a full shower system (water heater, pump capacity, waterproofing, ventilation) adds real cost that could go toward electrical or insulation instead.

Alternatives Worth Considering

  • Outdoor shower attachment: a simple hose/showerhead off the water pump system mounted at the rear door — no interior space cost, works well in warm climates.
  • Portable solar shower bags: zero permanent space cost, works anywhere there's sun to warm the bag, though slower and weather-dependent.
  • Gym memberships/campground showers: many full-time van lifers rely primarily on this, using an indoor or outdoor rinse setup only as a backup.

Frequently Asked Questions

How much space does an indoor shower need in a van? A compact wet bath or shower stall typically needs at least 30-36 inches square of floor space, which is a significant percentage of total floor space on shorter wheelbase vans.

Do I need a separate water heater for an indoor shower? Not strictly, but most people find cold showers impractical for regular use — options range from small 12V/propane on-demand heaters to pre-heating water via engine coolant loops in some builds.

Is an indoor shower worth it for van life? Depends heavily on your travel style — full-time and cold-climate builds often find it worth the space cost, while trip-based builds relying on campground/gym showers often prefer using that space for kitchen or storage instead.
