For instance, the Porta Potti Curve Portable Toilet is their most economical option, costing less than 100 dollars. On the other hand, their high-end product is the Tecma Silence Plus 2G Macerating Toilet, which can cost up to 1,500 dollars.

In terms of warranty offerings, both Thetford and Dometic provide limited warranties on their products. Thetford’s warranty ranges from one to three years, depending on the product, while Dometic’s warranty typically lasts two years.

Design and Features Comparison

Size and weight are important considerations when choosing an RV toilet. Thetford offers a range of sizes from compact to standard, while Dometic’s toilets are generally larger. But Dometic’s toilets are made with lightweight materials such as plastic and ceramic, making them easy to install and move around.

Material quality is another factor to consider. Both brands use high-quality materials such as porcelain and ceramic for their bowls. However, Thetford’s Aqua-Magic V toilet has a bowl made of plastic which may not be as durable as other materials.

Size and Weight Comparison

When selecting the right RV toilet, size and weight are important factors. Both Thetford and Dometic offer a range of sizes and weights for their RV toilets, so choosing one that suits your needs is essential.

Thetford offers a variety of sizes for their toilets, ranging from compact models like the Porta Potti Curve with a weight of 12.79 pounds to larger models like the Aqua-Magic V with a weight of 37.6 pounds.

As a counterpoint, Dometic offers a wider range of sizes for their RV toilets, from the smaller 2.6-gallon portable toilet weighing just 8.5 pounds up to larger models like the MasterFlush 7640. The MasterFlush 7640 is designed for larger RVs and boats and features a large bowl size and a powerful flushing system.

When considering size and weight, it’s important to remember that larger models may be more comfortable but may also take up more space in your RV bathroom. Also, lighter models may be easier to move around but may not have as many features as heavier models.

Material Quality and Durability

Material Quality and Durability

Material durability and quality are crucial when choosing the right RV toilet. Both offer a range of materials for their RV toilets, including plastic and ceramic.

Thetford’s Aqua-Magic V RV Toilet is made of high-grade, lightweight plastic yet durable. It features a textured lid that resists scratches and scuffs and a full-size residential seat for added comfort. The bowl is also made of plastic, which makes it easy to clean and maintain.

Meanwhile, Dometic’s 310 Series RV Toilet boasts a ceramic bowl that is not only durable but also provides a more home-like feel. The ceramic material is resistant to scratches and stains, making it easier to keep clean. The toilet seat is made of plastic for added comfort.

Regarding overall durability, both Thetford and Dometic have received positive customer reviews. But, some users have reported issues with the flushing mechanism on certain models from both brands.

Bowl Shape, Flushing System, and Water Usage

Regarding RV toilets, the bowl shape, flushing, and water usage are important factors. Thetford and Dometic offer various toilet models with different features in these areas.

Bowl Shape: Thetford offers toilets with a round bowl shape, while Dometic offers both round and elongated bowl shapes. The elongated bowl shape may be more comfortable for some people but it also takes up more space in the RV bathroom.

Flushing System: Thetford and Dometic offer gravity and macerating flush systems. Gravity flush rv toilet systems use gravity to move the waste from the bowl to the holding tank, while macerating flush systems use a motor to grind up waste before moving it to the holding tank.

Water Usage: Thetford toilets typically use less water per flush than Dometic toilets. Thetford’s Aqua-Magic V model uses just 0.5 gallons of water per flush, while Dometic’s 320 series uses 0.7 gallons. But some Dometic models have adjustable water levels, which can help reduce overall water usage.

Odor Control Features

When it comes to RV toilets, odor control is a crucial feature that can make or break the overall experience. Both Thetford and Dometic come with various odor control features to ensure a pleasant and hygienic environment inside your RV.

Thetford offers its Aqua-Magic V and Aqua-Magic Style II models with an antimicrobial seat that inhibits the growth of odor-causing bacteria. Also, their toilets have a seal to keep odors from escaping the holding tank.

On the other hand, Dometic’s 970 Series Portable Toilet has a powerful odor control system that uses chemicals and ventilation to eliminate unpleasant smells. Their toilet also features a leak-proof design that prevents unwanted odors from escaping.

Installation Process Comparison

Regarding the installation process, both Thetford and Dometic RV toilets are designed to be compatible with most RV models. However, some differences should be considered before making a purchase.

Thetford toilets have a universal floor flange and mounting bolts, making them easy to install in most RVs. Some models also come with a flexible water hose for easy connection to the water supply.

Dometic toilets may also have a common floor flange and screws for easy installation. They also offer an optional riser kit for their toilets. But depending on the specific model and RV setup, Dometic toilets may require extra parts, such as a vacuum breaker or waterline adapter.

Compatibility with Different RV Models

When choosing an RV toilet, compatibility with your specific RV model is a crucial factor to consider. Thetford and Dometic provide a range of toilets compatible with most RV models, but some differences exist.

Thetford offers a broader range of toilet options than Dometic, meaning they have more models catering to different RV types. Their website also has a compatibility chart that lets you easily determine which model will fit your specific RV.

Conversely, Dometic has toilets specifically designed for certain RVs, such as Class A or Class C motorhomes. This means that if you own one of these specific types of vehicles, a Dometic toilet model may be better suited for your needs.

Required Tools and Additional Parts for Installation

Thetford and Dometic RV toilets come with installation instructions, but there may be some differences in the required tools and parts.

Thetford RV toilets typically require a few essential tools for installation, such as a wrench and screwdriver. Some models may also require a sealant or adhesive for securing the toilet to the floor.

Also, Thetford offers a range of replacement parts and stuff for their toilets, including seals, valves, and flush pedals. These can be purchased separately if needed.

Dometic RV toilets also require essential tools for installation. But some models may require additional parts, such as mounting brackets or flange seals. Dometic also offers replacement parts and accessories for their toilets, including valves, seals, and spray heads.
