Sustainable RV Shower DIY: Water and Energy Conservation

For the eco-conscious traveler, a sustainable rv shower diy approach is essential. Integrating smart technologies and practices helps you conserve precious resources while enjoying your travels. These are some eco-friendly rv shower diy strategies.

Low-Flow Fixtures and Showerheads

The simplest way to save water is at the point of use.

  • Aerated Showerheads: These mix air with water, creating a satisfying spray with less actual water flow. Look for models with flow rates of 1.5 GPM (gallons per minute) or less.
  • Shut-Off Valves: Install a momentary shut-off valve on your showerhead. This allows you to easily pause water flow while lathering, then resume at the same temperature.
  • Composting Toilets: While not directly shower-related, reducing blackwater production (by using a composting toilet) means your greywater tank can hold more shower water, extending your time off-grid.

Greywater Management

Responsible management of greywater (water from sinks and showers) is vital for sustainability.

  • Larger Greywater Tank: If possible, upgrade to a larger greywater tank to accommodate more showers between dumps.
  • Filtration Systems: Consider a simple greywater filtration system to remove hair and soap residue, making the water safer for non-potable reuse (e.g., watering plants in designated areas, or flushing a toilet if your system allows).
  • Biodegradable Soaps: Always use biodegradable and phosphate-free soaps and shampoos. This minimizes your environmental impact if greywater is dispersed in approved areas.

Solar Heating Options

Harnessing the sun’s energy is a fantastic way to heat water without consuming propane or electricity.

  • Rooftop Solar Shower Bags: Simple, inexpensive bags that absorb solar heat. You can connect them directly to an outdoor shower hose.
  • DIY Solar Water Heater Coils: Create a coiled black PEX tubing system on your roof or a portable panel. Connect it to your RV’s water system for pre-heated water.
  • Heat Exchangers: Some advanced systems use the heat from your engine’s coolant to heat water while driving. This is a more complex installation but highly efficient.
