I have single ply construction walls and the boxes for the outlets are visible on the wall. The boxes are shallow and have to be replaced in order to be able to install new receptacles. Problem is, I can't find any electrical boxes that would work. Ideally, it would be 1.5" deep, made of plastic, no cutout lines or designs on boyd, and the box is perfectly rectangular and sides flat. So far, all the plastic boxes I've found are pretty flimsy and the sides are slightly slanted/diagonal and not flat.

How do I choose the right size surface mount electrical box?
Choosing the right size surface mount electrical box depends on the devices and wiring you plan to install. Consider these points:
- Device Type: Larger boxes are needed for multiple outlets, switches, or complex wiring setups.
- Wire Capacity: Make sure the box can accommodate the number and gauge of wires safely.
- Space for Connections: Allow extra room for wire nuts and connectors to avoid overcrowding.
- Outdoor Use: For outdoor installations, select weatherproof boxes with appropriate IP ratings.
Review product dimensions and specifications to match your installation needs before purchasing.
Can surface mount electrical boxes be installed on any wall type?
Surface mount electrical boxes are versatile and can be installed on various wall types including drywall, concrete, brick, and wood. Here are some tips:
- Mounting Hardware: Use appropriate anchors or screws suited for the wall material to ensure a secure fit.
- Surface Preparation: Clean and level the installation area to help the box sit flush against the wall.
- Accessibility: Position the box where wiring can be easily routed and devices accessed.
Proper installation techniques help maintain safety and functionality regardless of wall type.
How can I protect outdoor electrical outlets with surface mount boxes?
Protecting outdoor electrical outlets is important for safety and durability. Surface mount weatherproof boxes are a great solution. Consider these tips:
- Choose Weatherproof Boxes: Look for boxes with an IP rating suitable for outdoor exposure to keep moisture out.
- Use Gasketed Covers: Covers with rubber gaskets provide a tight seal against rain and dust.
- Proper Sealing: Seal around cable entry points with silicone or appropriate sealants to prevent water intrusion.
- Regular Inspection: Periodically check the box and cover for damage or wear to maintain protection.
These steps help ensure your outdoor outlets stay safe and functional.

I am assuming you are trying to install a switch leg for the disposal and a continuous hot for the dishwasher and the disposal and, dishwasher are on the same circuit, and you are trying to use a split duplex for both devices. I am also assuming that you are trying to surface mount the box inside the cabinet rather than use a cut-in box.
If you are installing a surface mounted box the conductors or cabling would have to protected no mater what kind of box you are using. If you came out of the side you would have to protect the conductors until you could pass into the interior of the wall or some other protected area.
One other problem exists the dishwasher circuit requires GFCI protection and the disposal doesn't. So if you do not have GFCI protection for this circuit you cannot put a split receptacle in under the cabinet. You would have to install two separate receptacles (at least one GFCI protected) or add a GFCI breaker to that circuit.
Taking this one step further. Since the NEC requires at least the dishwasher to be GFCI protected, it would be safe to assume that the area below the sink is considered by AHJ to be a wet location which would mean an "outdoor gang box" would be required in a surface mounted box.
FYI - The new 2020 NEC has modified 210.18 (A) which will require every 120V outlet to be GFCI protected including disposals, as well as any other wet location inside and outside a dwelling.
Hope this helps
Given a choice, metal is always the way to go, unless it's impossible for some reason. Metal is both grounded and a good heat conductor, so it will do a much, much better job of containing a variety of wiring faults. It also has standard knock-outs, so you can attach anything instead of only Romex cables.
Your description is good, search those words. There are plastic and metal boxes designed for surface raceways. But, as long as it has a knock-out in the back, you can use it alone.

While product recommendations are OT here, Wiremold makes fairly attractive shallow boxes that might meet your needs.
