What a Camper Van Shower Kit Actually Includes and How to Choose the Right One
Most people searching for a camper van shower kit already know they want a shower. The harder question is what a kit actually delivers versus what you still need to source, plumb, and install separately.
A shower kit is not a turnkey plumbing system. It is a packaged set of components designed to work together with a minimum of custom fabrication. Knowing what comes in the box prevents the most common buying mistake. That mistake is ordering a kit that covers the hardware but leaves the water system entirely to you.
What Is a Camper Van Shower Kit?
A camper van shower kit is a modular package of shower components assembled for van installation. It differs from a custom-plumbed van shower in that the components are pre-matched for DIY installation without bespoke fabrication.
What a kit is not: a complete water system. Most shower kits assume you already have a fresh water tank and a 12V pump. Grey water drainage is a separate system that most kits do not include. The full bathroom build decision, including grey tank sizing and layout planning, is a different step that comes before selecting a kit.
A kit simplifies the installation of the shower itself. It does not simplify the broader plumbing system the shower connects to.
Types of Camper Van Shower Kits
Four types cover the full range of what is available.
Outdoor rinse kits are the simplest option. A pressurized tank, a hose, and a showerhead designed for rinsing off after a beach or trail. Cold water only and portable. Best for weekend travelers who want a basic rinse solution without any van modification.
Basic indoor cold kits connect to the van's water supply and add an enclosure or curtain system for interior use. Still cold water only. These suit builds where a hot water system will be added separately later.
Hot water shower kits include either a propane on-demand water heater or an electric tank heater alongside the standard enclosure and drain components. These are the most complete packaged option for full-time use.
Full wet bath kits bundle an enclosure, drain pan, curtain or door, showerhead, and sometimes a small toilet compartment. These are the closest a kit comes to a complete shower room. Installation is more involved and typically requires a dedicated van section.
Van life shower options span a wide range of setups, from basic cold-water portable rinse kits through to full propane hot water systems. The right type depends on how often you shower, whether you need hot water, and the enclosure space available.
What Every Kit Should Include
A quality camper van shower kit should include these components as standard. The absence of any one of them signals a kit that will require significant additional sourcing.
Water supply connection. A fitting or valve that connects to your van's fresh water tank and pump. Budget kits may include only a hose adapter without pressure regulation.
Showerhead with flow control. A low-flow van-specific showerhead, not a standard household head. Van showers operate on small tanks. A high-flow head drains them in minutes.
Grey water drain fitting. A drain outlet with a trap to prevent odor from the grey tank. The component most often missing from entry-level kits.
Enclosure or curtain system. The containment that keeps water from spreading through the van. Fabric curtains mold over time. Waterproof vinyl or composite materials last significantly longer.
Pump (if the kit includes a standalone tank). A 12V submersible or inline pump sized to the tank capacity.
Understanding what is typically bundled in conversion van kits versus what must be sourced separately applies directly to shower kits. The gap between what a kit lists and what it delivers on arrival is where most buyers run into problems.
Key Specs to Compare Before Buying
Tank capacity determines shower duration. A 2-gallon tank supports a short rinse. A 5-gallon tank gives a full shower for one person. Ten gallons provides two showers. If the kit includes a standalone tank, verify capacity before ordering.
Flow rate (GPM) affects pressure and duration. Van showerheads typically run 0.5 to 1.5 GPM. Higher flow rates feel better but drain the tank faster. A 0.75 GPM head is a reasonable balance for off-grid use.
Hot water method has the biggest downstream impact.Tankless on-demand heaters for van use deliver continuous hot water as long as supply runs. Propane on-demand heaters are the most practical for off-grid. Electric tank heaters require shore power or a large battery bank to be reliable.
Power draw on 12V pumps and electric heaters matters in builds with limited battery capacity. Electrical system design and insulation quality affect how much power the shower system draws in cold conditions. This is a detail rarely addressed in kit specifications.
Drain compatibility with your grey water setup is worth confirming before purchase. Not all kit drains connect easily to standard grey tank fittings.
Camper Van Shower Kit vs Custom Integrated Build
A camper van shower kit is the right call for DIY builders, budget builds, and van lifers who shower occasionally. Most kits install in a day with basic tools and standard fittings.
A custom integrated shower suits full-time van lifers who shower daily. It also suits builds with hot water on demand and anyone wanting the shower integrated with the full plumbing layout. The gap between a budget kit and a professionally integrated water system is significant in long-term reliability and daily comfort.
Mold is the most common long-term problem with shower kits in vans. Inadequate sealing, poor drain placement, and low-quality enclosure materials all contribute. A professional build addresses each of these at the design stage.
Maintaining a van conversion requires inspection that most van owners skip until a problem appears. Shower drain seals, grey tank connections, and enclosure materials all degrade over time. Mango Vans builds custom van conversions out of South Florida with integrated shower and water systems designed for long-term use.

Frequently Asked Questions
What is a camper van shower kit?
A packaged set of shower components (pump, drain, showerhead, enclosure) designed to install as a unit in a cargo van. It is not a complete water system. You still need a fresh water tank and grey water drainage.
What is the difference between a cold and hot water shower kit?
Cold water kits connect to your fresh water supply with no heating element. Hot water kits add a propane on-demand heater or electric tank heater. Hot water kits cost more but deliver a meaningfully better experience for regular use.
How much water does a camper van shower use?
A standard shower with a 0.75 GPM showerhead uses 3 to 5 gallons in a 4 to 6 minute shower. Most van builds target a 5 to 10 gallon fresh water tank for single-day shower use.
Do shower kits include grey water drainage?
Most basic kits do not. Drain fittings are often included, but the grey tank, hose, and valves are separate purchases. Verify grey water components before ordering.
Can I install a camper van shower kit myself?
Yes, for most basic and intermediate kits. You need basic plumbing knowledge, standard fittings, and a sealed drain connection. Hot water propane kits require more care around gas connections and ventilation.
What floor material works best under a van shower?
Vinyl or fiberglass pan inserts are the most water-resistant. Standard subfloor plywood requires thorough waterproofing before any wet area installation. Most full wet bath kits include a shower pan. Standalone kits usually do not.
How do I prevent mold in a van shower?
Adequate ventilation through a roof fan, waterproof enclosure materials, a properly sealed drain, and cleaning after each use. Fabric curtains should be dried when not in use. Composite or vinyl enclosures are easier to keep mold-free.
Is a shower kit enough for full-time van life?
For occasional showers, yes. For daily use, a custom-integrated system with properly sized tanks and a hot water heater performs significantly better over months of use.
What should I look for in a quality shower kit?
A low-flow showerhead, a grey water drain fitting, waterproof enclosure materials, and a pump sized to the tank. A kit without a grey water drain is incomplete regardless of other features.
How does a shower kit affect my van layout?
The enclosure takes up floor space, typically 2 to 4 square feet depending on type. This space is committed once installed. Plan the shower location before committing to any other furniture placement.
