A floor drain with a trap can help block sewer gases while moving water away from the floor, but the right choice depends on your pipe size, drain style, and installation setting. These three options range from a compact PVC drain with an integral trap to larger cast-iron drains designed for heavier-duty use. Compare their connections and trap designs before choosing, and confirm that the drain fits your plumbing and local code requirements.

Our Picks: Best Floor Drain With Trap reviews
SUPPLYGIANT Cast-Iron Bell Trap for a Large No-Hub Drain
The SUPPLYGIANT is a large cast-iron floor drain with an attached bell trap. Its 12-by-12-inch size and no-hub connection make it a different kind of choice from the smaller PVC PROFLO drain. Check the dimensions and pipe connection before buying, especially if you are replacing an existing drain.
The drain has a hinged lid for access, and its black cast-iron body weighs about 20 pounds. That solid construction may suit a project where a substantial drain assembly is preferred. Its listed height is approximately 4.7 inches, so include that measurement when checking the available space below the finished floor.
This option is most relevant when you specifically need a bell-trap design and a no-hub connection. The product data marks it as unavailable, so verify its listing status before making plans. Unlike the PROFLO, the supplied specifications do not state a pipe diameter or a trap-seal depth.
Pros:
- Cast-iron construction with a substantial listed weight
- Attached bell trap
- No-hub connection for joining to standard no-hub drain lines
- Hinged lid provides access to the drain
Cons:
- The supplied listing data marks the product unavailable
- Confirm dimensions and connection compatibility; the supplied details do not specify a pipe diameter
Verdict: Choose the SUPPLYGIANT if its bell-trap design, no-hub connection, and large cast-iron format match your project—and confirm it is available before you rely on it.
Vodaland Cast-Iron Floor Trap for Heavy-Duty Areas
The Vodaland is a 12-by-12-inch cast-iron floor trap drain aimed at more demanding settings. Its product description names driveways, warehouses, and garages as intended uses. It is listed as C-load class, with up to 55,000 pounds of support. That stated capacity is a product specification, not a substitute for checking the complete installation and load requirements for your site.
The drain uses a hydro-lock system that is described as allowing water through while keeping gases out. Its lid is described as bolted down and hinged for maintenance access, while the product title also identifies a removable grate. Before installation, confirm how the grate and lid are configured and how the unit connects to your drain line; the supplied details do not state a pipe size.
Compared with the SUPPLYGIANT, the Vodaland emphasizes a stated load class and hydro-lock system rather than an attached bell trap and no-hub connection. It may suit a project where those specific features matter, but it is not the clearest fit if you need a listed pipe size or a conventional integral trap seal.
Pros:
- Cast-iron construction in a 12-by-12-inch format
- Listed C-load class with up to 55,000 pounds of support
- Hydro-lock system is described as helping keep gases out
- Bolted, hinged lid provides access for maintenance
Cons:
- The supplied details do not specify a drain-line connection size
- Confirm the lid and grate arrangement for your installation before ordering
Verdict: The Vodaland is the strongest match of these three for a heavy-duty setting when its load class and hydro-lock design fit your project and the connection details are confirmed.
PROFLO PVC Drain with a Built-In Trap Seal
The PROFLO PF800P is a PVC floor drain with an integral trap, so the trap is part of the drain body rather than a separate assembly. Its specifications list a full 3-inch trap seal, a 3¾-inch-deep sump bowl, and a connection for 2-inch Schedule 40 pipe. Those details make this the most clearly specified option here for shoppers who already know they need that pipe size.
The one-piece body keeps the drain and trap together, and the polypro strainer covers the sump bowl. The product also includes a backwater device intended to prevent backflow through the floor drain. That feature is specific to the drain opening; it should not be treated as a guarantee against all water intrusion or as a replacement for a broader backwater plan.
Compared with the larger cast-iron options, the PROFLO has a more specific connection size and trap-seal description, but it is not presented with a heavy-duty load rating. It is a practical candidate when your plans call for 2-inch Schedule 40 pipe and an integral trap. Confirm the body dimensions and installation requirements before committing to it.
Pros:
- Integral trap with a listed 3-inch trap seal
- Fits 2-inch Schedule 40 pipe
- One-piece drain body
- Includes a backwater device designed to prevent backflow through the floor drain
Cons:
- Its 2-inch connection may not match larger drain-line plans
- The supplied specifications do not list a heavy-duty load class
Verdict: Choose the PROFLO when your project calls for a 2-inch PVC connection and an integral trap with a clearly stated seal depth; look elsewhere if you need a large cast-iron drain or a stated heavy-load rating.
How to Choose a Floor Drain With a Trap
Match the drain to your pipe size and connection
Start with the drain line, not the appearance of the grate. The PROFLO is specified for 2-inch Schedule 40 pipe, while the SUPPLYGIANT uses a no-hub connection but does not list a pipe diameter in the supplied details. The Vodaland’s supplied description also does not state a connection size. Check the drain body, pipe material, and connection type against your plumbing plan before ordering.
Understand the trap design
Trap designs are not interchangeable by name alone. The PROFLO lists an integral trap and a 3-inch trap seal. The SUPPLYGIANT has an attached bell trap, while the Vodaland describes a hydro-lock system. Confirm that the design you choose meets the needs of your installation and local plumbing rules. If a floor drain is used infrequently, ask your plumber whether the trap needs any routine attention to maintain its water barrier.
Choose a material and load class for the setting
Cast iron is used in both the SUPPLYGIANT and Vodaland models, while the PROFLO is PVC. For areas exposed to vehicle or equipment loads, pay close attention to the drain’s stated load class and installation requirements. The Vodaland is listed as C-load class with up to 55,000 pounds of support; do not assume that rating applies to another drain or to an installation that does not follow the manufacturer’s instructions.
Check dimensions and access
Make sure the drain fits both the floor opening and the space beneath it. The two cast-iron models are 12 by 12 inches, and the SUPPLYGIANT is approximately 4.7 inches tall. Check depth, grate placement, and clearance for the pipe connection as well as the visible top dimensions. A hinged or removable lid can help with access, but confirm how it opens and whether it needs to be unbolted.
Consider backflow protection separately
The PROFLO includes a backwater device described as preventing backflow through the floor drain. That may be useful for projects where backflow through that opening is a concern, but it does not establish protection for every drain or every source of flooding. Ask a qualified plumber what protection your site requires and whether the selected drain is suitable.
Verify code and installation requirements
A product’s listed features do not by themselves confirm that it is permitted for every project. Check local plumbing requirements, installation instructions, and any needed approvals with a qualified professional. This is especially important when replacing an existing drain, connecting to a different pipe material, or installing a drain in an area with vehicle or equipment loads.
Frequently Asked Questions
What does a trap do in a floor drain?
A trap is designed to hold a water barrier between the drain and the drain line, which can help block sewer gases from coming back through the opening. The exact design varies, so check whether a product uses an integral trap, a bell trap, or another system.
Which of these drains has a specified trap-seal depth?
The PROFLO PF800P lists a full 3-inch trap seal. The supplied specifications for the SUPPLYGIANT and Vodaland do not state a trap-seal depth.
Which option connects to 2-inch Schedule 40 pipe?
The PROFLO is specified to fit 2-inch Schedule 40 pipe. The supplied product details do not list a pipe size for the SUPPLYGIANT or Vodaland.
Which drain is intended for a heavy-duty setting?
The Vodaland is described for driveways, warehouses, and garages, and is listed as C-load class with up to 55,000 pounds of support. Confirm the installation requirements and load needs for your specific site.
Does the PROFLO backwater device prevent all flooding?
No. Its description says the device is installed to prevent backflow through the floor drain. That claim does not mean it prevents all flooding or water entry from other parts of a building.
Is the SUPPLYGIANT available to buy?
The supplied product data marks it unavailable. Availability can change, so check the product listing before planning around this model.
Do I need a plumber to install a floor drain?
Installation depends on the existing piping, floor construction, and local requirements. If you are unsure about the connection, trap design, or code rules, consult a qualified plumber before purchasing or installing a drain.
Final Recommendation
For a clearly specified 2-inch PVC installation, the PROFLO is the most straightforward choice because its integral trap, seal depth, and pipe size are stated. For a heavy-duty project, consider the Vodaland after verifying the connection and installation requirements. The SUPPLYGIANT may suit a project that specifically calls for an attached bell trap and no-hub cast-iron drain, but its supplied availability status is a reason to check the listing first. Match the drain to your pipe, load needs, and local requirements before you buy.
