Guide to Boating Toilets: Everything You Need to Know

Boating is an incredible way to explore the open waters, but one essential aspect that often goes overlooked is the boating toilet. Whether you’re planning a short-day trip or an extended voyage, having a reliable and comfortable toilet on board is crucial. In this guide, we’ll cover everything you need to know about boating toilets, from the different types available to the features, specifications, and prices.

Types of Boating Toilets

Boating toilets come in various types, each with its advantages and disadvantages. Here are the main types you should consider:

1. Portable Toilets

Portable toilets, often referred to as “porta-potties,” are self-contained units that are easy to transport and install. These are ideal for small boats with limited space or for boaters who need a temporary solution.

  • How They Work: Portable toilets have a freshwater tank for flushing and a separate waste tank for holding waste until it can be emptied.
  • Pros: Affordable, easy to install, and no plumbing required.
  • Cons: Limited capacity, manual waste disposal.

Price Range: $50 – $200
Popular Models: Thetford 92820 Porta Potti ($140), Dometic 301097202 Portable Toilet ($130)

2. Cassette Toilets

Cassette toilets are similar to portable toilets but are built into the boat and often have a removable waste tank (cassette) that can be emptied.

  • How They Work: These toilets are fixed in place, with a waste cassette that can be easily removed for disposal.
  • Pros: More permanent than portable toilets, easy to empty.
  • Cons: Limited waste capacity, not suitable for long trips.

Price Range: $150 – $500
Popular Models: Thetford C200 Cassette Toilet ($400), Dometic CTS4110 ($300)

3. Marine Composting Toilets

Composting toilets are eco-friendly options that break down waste into compost, reducing the need for water and chemicals.

  • How They Work: These toilets use aerobic decomposition to break down waste into compost. Liquids are separated from solids, with solids being composted and liquids often being evaporated or stored for later disposal.
  • Pros: Environmentally friendly, no need for holding tanks, low water usage.
  • Cons: Requires regular maintenance, more expensive, needs ventilation.

Price Range: $900 – $1,800
Popular Models: Nature’s Head Composting Toilet ($1,030), Air Head Composting Toilet ($1,100)

4. Manual and Electric Marine Toilets

These are the most common types of permanent marine toilets, often found on larger boats and yachts. They are either manually operated or powered by electricity.

  • How They Work: Manual toilets use a hand pump to flush waste into a holding tank, while electric toilets use a motorized pump.
  • Pros: Reliable, can handle a higher volume of waste, connected to a holding tank.
  • Cons: More complex installation, requires plumbing and sometimes electricity.

Price Range: $200 – $1,500
Popular Models: Jabsco 37010 Electric Marine Toilet ($600), Raritan PH SuperFlush Manual Toilet ($450)

5. Vacuum Toilets

Vacuum toilets are high-end marine toilets often found on luxury yachts and commercial vessels. They use a vacuum to flush waste into a holding tank.

  • How They Work: These toilets use a vacuum to rapidly and efficiently move waste from the toilet bowl to the holding tank.
  • Pros: Highly efficient, low water usage, can be installed at any angle.
  • Cons: Expensive, complex installation, requires a vacuum pump.

Price Range: $1,000 – $3,000
Popular Models: Dometic 504875 Vacuum Toilet ($1,800), Raritan Vortex-Vac Toilet ($2,500)

Features to Consider

When choosing a boating toilet, several key features should be considered:

1. Flushing Mechanism

  • Manual vs. Electric: Manual toilets are generally more reliable and require no power, while electric toilets offer convenience at the cost of requiring electricity.
  • Water Usage: Some toilets use minimal water, which is crucial for conserving onboard resources.

2. Waste Storage and Disposal

  • Holding Tank Size: Larger tanks mean less frequent emptying but require more space.
  • Disposal Options: Consider where and how you can legally dispose of waste. Some boats may require additional equipment like a macerator pump for easier disposal.

3. Comfort and Design

  • Seat Height: Ensure the toilet is comfortable to use, particularly for extended periods.
  • Bowl Size: A larger bowl can be more comfortable but may take up more space.

4. Installation Requirements

  • Space: Measure your space carefully. Some toilets require more room for installation and operation.
  • Plumbing: Consider the complexity of plumbing required. Portable toilets need no plumbing, while built-in toilets will require a more permanent setup.

5. Maintenance

  • Ease of Cleaning: Look for materials that are easy to clean and maintain.
  • Parts Availability: Ensure that replacement parts are readily available for the model you choose.

Legal and Environmental Considerations

When using a boating toilet, it’s essential to be aware of legal and environmental regulations:

1. Marine Sanitation Devices (MSDs)

In many regions, boats with toilets must have a Marine Sanitation Device (MSD) to treat or store waste. There are three types:

  • Type I: Treats waste to meet specific standards before discharge.
  • Type II: Similar to Type I but for larger vessels.
  • Type III: Stores waste in a holding tank for later disposal.

2. Disposal Regulations

  • No-Discharge Zones: Some areas prohibit the discharge of any treated or untreated waste. Always check local regulations.
  • Pump-Out Stations: These are available in many marinas for legal and safe waste disposal.

3. Environmental Impact

  • Eco-Friendly Options: Consider composting toilets or low-flush models to reduce water usage and environmental impact.

Conclusion

Choosing the right boating toilet is essential for comfort, convenience, and compliance with regulations. Whether you opt for a simple portable unit or a high-tech vacuum toilet, understanding the different types, features, and maintenance requirements will help you make an informed decision.

With prices ranging from under $100 to several thousand dollars, there’s a boating toilet to fit every budget and need. By considering factors such as space, installation, and waste disposal, you can ensure that your time on the water is both enjoyable and environmentally responsible.

Remember to always follow legal requirements for waste disposal and consider the environmental impact of your choices. Happy boating!
