1. RecPro 3-in-1 Van Bathroom Kit: Best Overall

🛒  Check Price on Amazon →

We found the RecPro 3-in-1 to be the most complete kit for van conversions. It integrates a cassette toilet, a fold-down sink, and a shower pan with a hand-held shower head into one module. Owner feedback highlights the ease of installation and the sturdy ABS plastic that does not warp. The cassette toilet is a practical choice for van life, as it can be emptied at any standard dump station.

However, the lack of a fixed overhead shower head may disappoint those who prefer hands-free showering. This kit is best for DIY builders who want a turnkey bathroom solution and are willing to accept a simple shower setup. It is not ideal for those who require a separate dry bathroom or a larger shower enclosure.

• All-in-one design with toilet, shower, and sink in a single module
• Compact footprint saves space for other living areas
• Cassette toilet is easy to empty and maintain

Pros: Complete solution with no need to source separate components; High-quality ABS construction resists moisture and odors
Cons: Shower head is hand-held only, no fixed overhead option

2. Dometic 9720 Portable Toilet with Shower Kit: Best Portable Option

🛒  Check Price on Amazon →

The Dometic 9720 is a popular choice among van lifers who value flexibility. The toilet itself is a high-quality electric flush model with a comfortable seat. The optional shower kit includes a handheld sprayer and hose that can be attached to the toilet’s fresh water tank. Based on owner feedback, this setup works well for quick showers but lacks a dedicated shower pan.

While the portability is a plus, the lack of a fixed shower enclosure means you will need to set up a privacy tent or use it in a wet bath area. This kit is best for those who want a reliable toilet and occasional shower capability without a permanent installation. It is not suitable for full-time van dwellers who need a dedicated shower daily.

• Electric flush with pulsating rinse
• Shower attachment connects to fresh water tank
• Lightweight and removable for cleaning or use outside

Pros: Very portable; can be used outside the van; Toilet is comfortable and reliable
Cons: Shower kit is separate and not integrated; Requires external water source or separate pump

3. Trelgo 4-in-1 Van Bathroom Module: Premium Choice

🛒  Check Price on Amazon →

The Trelgo 4-in-1 stands out for its build quality and features. It comes pre-assembled with a toilet, shower, sink, and vanity mirror. The overhead rain shower head is a rare find in compact van kits, and owner reviews praise the water pressure. The module uses a composting toilet, which eliminates the need for black water tanks.

However, the unit is heavy and may not be suitable for smaller vans like a minivan. It also requires a composting toilet routine that some may find less convenient than cassette. This kit is best for those building a larger van (Sprinter, Transit, Promaster) and wanting a high-end bathroom. It is not ideal for budget builds or those who prefer traditional flushing toilets.

• Pre-assembled unit reduces installation time
• Integrated sink with mirror and storage
• Shower with overhead rain head and hand-held sprayer

Pros: Premium finish with a sleek, modern look; Overhead rain shower provides a luxurious experience
Cons: Heavy and may require reinforced mounting

4. Dometic 9710 Toilet and Shower Combo: Budget Friendly

🛒  Check Price on Amazon →

The Dometic 9710 is an entry-level combo that combines a cassette toilet with a shower sprayer. The toilet lid can be removed to use the unit as a shower pan, and the included hand-held sprayer provides water. Owner feedback notes that while it works in a pinch, the shower experience is messy and water tends to splash onto the floor.

This kit is best for weekend campers or those on a tight budget who want a minimal bathroom. It is not recommended for full-time use, as the toilet comfort and shower functionality are limited. If you prioritize a comfortable shower, consider a higher-tier option.

• Toilet doubles as a shower base with removable sprayer
• Compact design fits tight spaces
• Easy to install with basic tools

Pros: Very affordable compared to separate components; Space-saving dual function
Cons: Shower function is basic and water spills easily; Seat is less comfortable than dedicated toilets

5. RecPro 2-in-1 Van Toilet and Sink Combo: Space Saver

🛒  Check Price on Amazon →

The RecPro 2-in-1 is a clever space-saving solution. The sink folds down over the toilet, and the gray water from the sink is used to flush the toilet. This reduces water usage and eliminates the need for a separate sink. Based on spec sheets, it is one of the most compact options available.

However, this kit does not include a shower, so you will need to plan for a separate shower solution. The sink is also quite small, making it difficult to wash larger items. This kit is best for van builds where space is at a premium and a separate shower is acceptable. It is not ideal for those who want an all-in-one bathroom.

• Sink folds over toilet when not in use
• Uses gray water from sink to flush toilet
• Requires minimal floor space

Pros: Innovative water-saving flush system; Very compact; fits in narrow areas
Cons: No shower included; must be added separately; Sink is small and may splash

6. Nature's Head Composting Toilet with Shower Kit: Eco Friendly

🛒  Check Price on Amazon →

Nature’s Head is a well-known composting toilet brand. This kit pairs their toilet with a shower pump and sprayer. The toilet is highly durable and separates waste efficiently. Owner feedback often mentions the lack of odors when used correctly. The shower kit is functional but minimal, requiring you to provide your own shower enclosure.

This kit is best for eco-conscious van dwellers who are comfortable with composting toilet maintenance. It is not ideal for those who prefer a flush toilet or want a complete shower enclosure. The shower component is an add-on, so it may not satisfy those seeking a fully integrated bathroom.

• No water or chemicals needed for toilet
• Separates liquids and solids for easy composting
• Shower kit includes 12V pump and hand-held sprayer

Pros: Environmentally friendly; no black water tank; Durable stainless steel and plastic construction
Cons: Composting requires regular maintenance; Shower kit is basic and lacks enclosure

7. Camco 40003 Portable Toilet and Shower Enclosure: Best Budget Combo

🛒  Check Price on Amazon →

The Camco 40003 is an entry-level set that includes a portable toilet and a pop-up privacy tent with a shower attachment. It is designed for camping and occasional use. Based on owner feedback, the tent is easy to set up but not very durable in windy conditions. The toilet is functional but less comfortable than larger models.

This kit is best for occasional campers or those on a very tight budget. It is not suitable for full-time van life, as the toilet capacity is small and the tent is not built for daily use. For a more permanent van conversion, we recommend investing in a dedicated kit.

• Includes portable toilet and privacy tent
• Tent has built-in shower attachment and drain
• Toilet is lightweight and easy to carry

Pros: Very affordable complete solution; Tent provides privacy and a shower area
Cons: Toilet is small and low to the ground; Tent is not wind-resistant and may leak

Frequently Asked Questions

What should I look for in a van conversion kit with a bathroom?

Key factors include the type of toilet (cassette, composting, or portable), shower configuration (hand-held vs overhead), water tank capacity, and overall footprint. Consider how much space you have in your van and whether you prefer a wet bath (combined toilet/shower) or separate dry bath. Also check the ease of emptying waste tanks and the quality of materials.

Can I install a van bathroom kit myself?

Many kits are designed for DIY installation with basic tools. Pre-assembled modules like the Trelgo 4-in-1 require minimal wiring and plumbing. However, some kits may need additional sealing and ventilation. Always follow the manufacturer’s instructions and consult a professional if you are unsure about electrical or water systems.

How much space do I need for a van bathroom kit?

Compact kits can fit in as little as 2 feet by 2 feet of floor space. Most kits are designed for standard van widths (about 5.5 feet). Measure your van’s interior carefully and account for needed clearance for opening doors and using the shower. Some kits require additional space for a shower curtain or enclosure.

Are composting toilets better than cassette toilets for vans?

Composting toilets do not require water or chemicals, and they produce compost that can be disposed of in trash. They are eco-friendly but require regular maintenance (mixing, emptying solids). Cassette toilets are easier to empty at dump stations and are more familiar to most users. The choice depends on your lifestyle and willingness to maintain the system.

Do I need a separate water heater for the shower in a van conversion kit?

Most kits do not include a water heater. You will need to install a separate propane or electric water heater, or use an on-demand system. Some kits include a shower head that connects to a pump and can use heated water from your van’s fresh water tank. Plan your water heating solution based on your climate and usage.
