SUPERFLO 750W Macerating Toilet System

The SUPERFLO 750W system uses a high-powered 750W macerator pump to move waste efficiently in basements or garages. It operates quietly, making it suitable for living spaces directly above or adjacent to the installation. The upflush design enables installation without major plumbing renovations, reducing upfront costs. This model includes four water inlets, enabling connections to a toilet, sink, shower, or laundry fixtures. It is positioned as a flexible upgrade for creating a functional bathroom in unconventional spaces.
Key considerations
- Suitable for basements and garages with limited space
- Four inlets support multiple fixtures in one system
- Quiet operation is important for living or work areas nearby
Laveo Dry Flush Toilet

The Laveo Dry Flush Toilet is a waterless, portable system designed for off-grid use. It includes a battery, charger, cartridges, and Pee Powder to extend cartridge life. There is no need for water or complicated plumbing. The cartridge-based waste handling seals odor inside, and disposal is straightforward by replacing spent cartridges. This option is ideal for tiny homes, vans, RVs, camping, or garages where a full plumbing setup isn’t feasible.
Key considerations
- Completely waterless and portable
- Cartridge-based waste with odor control
- Simple maintenance and straightforward disposal process
SUPERFLO Macerating Toilet System 500W

This 500W macerator option delivers solid performance in remote spaces such as basements or garages. It provides four water inlets, enabling a complete bathroom setup with a toilet, sink, shower, and potentially a washing machine. The upflush capability supports draining waste vertically and horizontally across considerable distances, which helps accommodate various room layouts and existing drain positions without major plumbing work.
Key considerations
- 500W motor balances power and efficiency
- Upflush range supports flexible layouts
- Four inlets enable full bathroom configurations
SUPERFLO 750W Macerating Toilet System (Another Model)

This model mirrors high-capacity maceration with a 750W motor and four inlets. It is suited for basements, garages, cabins, or other low-level installations where traditional plumbing is not practical. The upflush design supports moving waste to the main line or septic system with flexibility for wider layouts, and the four inlets enable a compact bathroom or utility area with multiple fixtures.
Key considerations
- High-powered 750W performance
- Versatile wiring for multiple fixtures
- Longer reach for drain lines through upflush
Waterless Urinal With Hose (Black)

This UV-resistant waterless urinal is designed for outdoor or garage use where plumbing runs are impractical. It is wall-mounted for easy installation and requires no flushing water. Odor and water conservation benefits are notable, making it a practical alternative for secondary or utility bathroom spaces in garages or sheds where traditional toilets aren’t feasible.
Waterless Urinal With Hose

A second waterless urinal option emphasizes ease of installation and upkeep. Like the hose model, it is suitable for locations without direct plumbing access and contributes to water savings. The ability to mount on a wall or fence makes it flexible for garage or outdoor setups where a traditional bathroom isn’t an option.
Buying Guide: Key Purchase Considerations
- Waste handling method: Macerating systems provide a traditional toilet experience without connecting to a main sewer line; dry flush and waterless options reduce water use and plumbing requirements.
- Installation environment: Basements and garages benefit from upflush capabilities and multiple inlets for adding fixtures without major renovations.
- Power and capacity: Higher wattage (e.g., 750W) offers stronger maceration for remote spaces; lower wattage (e.g., 500W) may suffice for smaller setups.
- Odor control: Dry flush and waterless models emphasize sealed cartridges or odor containment, important in enclosed spaces.
- Maintenance and accessories: Cartridge life, batteries, chargers, and replacement parts affect long-term cost and convenience.
- Portability vs. permanence: Dry flush solutions are highly portable, while macerating systems are more permanent but still don’t require traditional plumbing.
- Waste output and fixtures: Ensure four-inlet models can accommodate a toilet plus other utilities (sink, shower, washer) if you aim for a full secondary bathroom.
- Warranty and support: Check manufacturer warranties and availability of replacement pumps or cartridges in your region.
