1. Porta Potti 365: Best Overall
The Porta Potti 365 is a top choice for those who want a true flushing toilet experience in their car. With a 2.6 gallon freshwater tank and a 3.4 gallon waste tank, it offers ample capacity for weekend trips. The electric flush uses batteries (not included) to provide a thorough rinse, and the built-in waste tank has a secure seal to prevent odors. In our evaluation, owners consistently praised its reliability and ease of cleaning, though some noted that the weight (around 12 pounds when full) can be cumbersome.
However, this model requires more space than a simple bucket and may not suit minimalist travelers. It also needs periodic battery replacement for the flush pump. If you prioritize a home-like experience and have the room, the Porta Potti 365 is a strong performer. But for ultralight backpacking or very tight car interiors, consider a simpler option.
- Electric flush with fresh water rinse provides a clean, odor-free experience.
- Large waste tank capacity reduces frequency of emptying.
- Durable polyethylene construction resists cracking and leaks.
Pros: Reliable flush mechanism and seal.; Easy to empty and clean.
Cons: Heavier than basic bucket-style toilets.
2. Luggable Loo 5-Gallon Bucket Toilet: Best Budget
The Luggable Loo is a classic, no-frills portable toilet that converts any 5-gallon bucket into a functional commode. It comes with a sturdy snap-on seat lid that fits snugly, and the bucket itself can be used with double-bagging or chemical additives for waste management. Based on owner feedback, it is incredibly durable and easy to clean. The price point makes it accessible for anyone, and its simplicity means there is little to break.
That said, this is essentially a bucket with a seat. It lacks any flushing mechanism, so odor control depends entirely on your choice of bags or chemicals. It is not ideal for those who want a more sanitary, hands-free experience. If you are on a tight budget or need a backup option, the Luggable Loo is a solid choice, but skip it if you prefer a flush toilet.
- Uses a standard 5-gallon bucket (included) as base, very affordable.
- Snap-on seat lid seals tightly to contain odors.
- Lightweight and easy to store when empty.
Pros: Extremely low cost and widely available.; Simple, durable design with no mechanical parts.
Cons: No flush or waste containment system; requires disposable bags or chemicals.
3. Cleanwaste Go Anywhere Portable Toilet Kit: Best Lightweight
The Cleanwaste Go Anywhere kit is designed for maximum portability. It features a lightweight folding frame that supports up to 350 pounds, and the included seat attaches easily. The kit also comes with waste bags that use a gelling agent to control liquids and odors, plus a pop-up tent for privacy. In our research, owners appreciated how compact the whole system is when packed, making it ideal for small cars or emergency kits.
However, the waste bags are single-use and must be purchased separately, which adds ongoing cost. The frame, while sturdy, may feel less stable than a solid bucket or plastic toilet. If you prioritize weight and packability, this is a great option, but for frequent use, the ongoing bag expense might be a drawback.
- Foldable aluminum frame collapses to compact size for storage.
- Includes specially designed waste bags with odor-control polymers.
- Comes with a pop-up privacy tent for outdoor use.
Pros: Very portable and quick to set up.; Privacy tent adds convenience for roadside stops.
Cons: Waste bags are proprietary and can be costly.
4. Reliance Products Luggable Loo Folding Toilet: Compact Design
The Reliance Products Luggable Loo Folding Toilet offers a clever folding design that collapses into a flat package, saving space in your vehicle. It uses a standard 5-gallon bucket (not included) as the waste container, and the frame holds it securely. The seat is contoured for comfort, and the non-slip feet add stability. Owner feedback indicates it is reliable for occasional use and easy to store.
However, the seat height is only about 12 inches, which can be uncomfortable for adults over 5’8”. Additionally, you need to supply your own bucket, which may be an extra purchase. If you need a space-saving option and don’t mind a lower seat, this is a good choice, but taller users should look for a taller model.
- Folds flat for easy storage in car trunk.
- Removable bucket liner for simple waste disposal.
- Sturdy plastic construction with non-slip feet.
Pros: Very compact when folded.; Easy to clean with a smooth plastic surface.
Cons: Seat height may be low for taller users.
5. Trelino L Portable Toilet: Premium Choice
The Trelino L is a premium separating toilet that elevates the portable toilet experience. It uses a unique design that diverts liquids to a separate tank, while solids fall into a bin with a charcoal filter. This dramatically reduces odors and makes waste disposal more hygienic. The unit is well-built with a smooth finish and a comfortable seat height. In our evaluation, owners who have used it on long road trips and van conversions praised its performance and ease of maintenance.
The main downside is the price, which is significantly higher than bucket-style toilets. It also requires periodic replacement of the charcoal filter. If you are serious about comfort and odor control and are willing to invest, the Trelino L is outstanding. But for occasional emergency use, a simpler toilet may suffice.
- Separates liquid and solid waste for easier disposal and less odor.
- Charcoal filter in the solids bin neutralizes smells.
- Ergonomic design with a comfortable seat height.
Pros: Odor control is excellent with separation and filter.; Large capacity for extended trips.
Cons: Higher upfront cost compared to basic models.
6. Thetford Porta Potti 135: Compact Flush
The Thetford Porta Potti 135 is a more compact version of the classic Porta Potti, featuring a hand pump flush instead of an electric one. This eliminates the need for batteries and reduces weight. The unit has a 2.6 gallon freshwater tank and a matching waste tank, making it suitable for short trips or as a backup. Owner reviews highlight its reliability and the fact that it never runs out of battery power.
However, the waste tank capacity is smaller, so it may need more frequent emptying if used by multiple people. The hand pump requires a bit of effort to achieve a thorough rinse. If you want a flush toilet but have limited space, this is a good option, but for longer trips, consider the larger Porta Potti 365.
- Hand pump flush provides gentle water rinse without batteries.
- Compact size fits in small car trunks.
- Durable construction with easy-carry handle.
Pros: No batteries required for flush.; Lightweight and portable.
Cons: Waste tank capacity is smaller than larger models.
7. Stansport Portable Toilet: Basic Utility
The Stansport Portable Toilet is a basic bucket-style toilet that gets the job done without any frills. It comes with a 5-gallon bucket, a snap-on seat lid, and a small pack of waste bags. The bucket is made of durable plastic, and the seat is contoured for basic comfort. Based on owner feedback, it works well for emergency use or short trips where space is not a concern.
However, the seat is not padded, and the included bags are limited. You will need to buy additional bags or chemicals. The lack of a flush or separation system means odors can be an issue if not managed properly. If you need the cheapest option and are okay with a no-frills setup, this is fine, but for a more pleasant experience, upgrade to a model with better odor control.
- Simple bucket-and-seat design, includes a few waste bags.
- Lightweight and easy to carry.
- Lid snaps tight to contain odors.
Pros: Very affordable and straightforward.; No assembly required.
Cons: Seat may be less comfortable than padded options.
Frequently Asked Questions
What should I look for in a portable car toilet?
Consider capacity, ease of cleaning, odor control, and portability. Larger waste tanks mean less frequent emptying, but add weight. Look for models with sealing lids or flushing mechanisms to minimize smells. Also check the height and seat comfort, especially if you have limited mobility.
How do I dispose of waste from a portable car toilet?
Most portable toilets use waste bags or holding tanks. For bag-based systems, double-bag and dispose in designated trash receptacles. For tank models, empty into a RV dump station or a toilet, following local regulations. Never dump waste on the ground.
Can I use a portable toilet inside my car?
Yes, but ensure proper ventilation to control odors. Some models are designed for indoor use with tight-sealing lids and charcoal filters. Always secure the toilet to prevent tipping during travel. Consider using a privacy tent or curtain for modesty.
Are portable car toilets safe for children?
Many models are safe for children, but check weight limits and seat dimensions. Some toilets have smaller seats or require adult supervision. For young children, consider a potty seat insert that fits on a standard toilet.
How do I clean and maintain a portable car toilet?
Empty the waste tank or bag after each use. Rinse with water and a mild cleaner. For tank models, use RV-specific toilet chemicals to break down waste and control odors. Store in a dry, ventilated area. Replace seals and filters as recommended by the manufacturer.
