The best choice for a PVC tub drain elbow depends on the pipe diameter, connection style, and whether you need a simple bend or a larger drain repair. The 40 mm elbow is the most directly described right-angle bathtub fitting; the black ABS shoe-pipe kit is better for replacing a tub drain section. The other options cover tub waste assemblies, adapters, or larger drain lines, so check measurements and application before ordering.
| Product | Best suited for | Key detail |
|---|---|---|
| 40 mm PVC 90-degree elbow | Right-angle bath or sink waste routing | White PVC, 40 mm |
| ABS shoe-pipe repair kit | Replacing a tub drain shoe pipe | 1-1/2-inch diameter |
| Westbrass drain adapter | Connecting a tub without an overflow | 1-1/2-inch threaded and slip inlet |
| Flexible PVC elbow set | Large drain or sewer repair | 3-inch elbows with clamps |
| Westbrass bath waste assembly | Replacing a complete waste and overflow assembly | 1-1/2-inch tubular tubes |
40mm PVC 90-Degree Drain Elbow
Best for: Buyers who need a right-angle fitting for a bathtub, sink, or shower-tray waste connection and have confirmed that 40 mm is the correct size. The product is described as a white PVC 90-degree elbow for these types of drain applications.
The listed features state that the PVC construction resists moisture and common drain compounds. Its right-angle shape is intended to route waste pipe around an obstruction or through a change in direction. This is the most directly relevant option here for a PVC tub drain elbow.
Limitation: The listing specifies 40 mm, not 1-1/2 inch. Confirm the pipe and fitting measurements before choosing it; the description does not provide additional connection details.
1-1/2-Inch ABS Tub Shoe Pipe Repair Kit
Best for: A tub repair that calls for a replacement drain shoe pipe rather than a standalone elbow. This kit is made from black ABS and is specified as 1-1/2 inches in diameter, making it useful to consider when repairing an in-wall tub drain installation.
The product description also lists bathtub, bathroom sink, and motorhome applications. It identifies a coarse-thread strainer insert measuring 1-7/8 inches. Choose this kit if those dimensions and the repair scope match your existing drain assembly.
Limitation: This is a shoe-pipe repair kit, not a 90-degree elbow. Verify the strainer and pipe dimensions as well as the required material before purchase.
Westbrass Straight Tub Drain Adapter
Best for: Connecting a bathtub without an overflow to a drain pipe. This Westbrass adapter has a 1-1/2-inch NPMS thread and a 1-1/2-inch Schedule 40 slip inlet. It is a connection adapter rather than a bend, so it may suit a tub-drain project where the missing part is the transition to the pipe.
The listing describes the product as white Schedule 40 PVC and states that it allows a tub without an overflow to connect to a drain pipe. The two-pack can be useful when more than one matching connection is needed.
Limitation: It is a straight adapter, not an elbow. Check the tub configuration and connection type before selecting it.
Flexible 3-Inch PVC Drain Elbows
Best for: Drain and sewer repairs involving 3-inch pipe, especially when a flexible 90-degree turn or offset connection is needed. The set includes two short elbows and four stainless steel clamps. The product description says the flexible fittings can help with tight spaces and slightly misaligned pipe runs.
The listed installation method uses clamps rather than glue or primer. This makes the set distinct from a rigid tub waste elbow and may be useful for larger drain-line repairs.
Limitation: These fittings are 3 inches and are described for sewer, drainage, and DWV lines. Do not assume they fit a standard bathtub drain; confirm the pipe diameter and intended application.
Westbrass Tip-Toe Bath Waste Assembly
Best for: Buyers replacing a broader tub waste and overflow assembly instead of sourcing a single elbow. The kit includes 1-1/2-by-14-inch white poly slip-joint tubes, a foot-operated tip-toe stopper, and a two-hole overflow faceplate with color-matched screws.
The slip-joint tubes are described as providing a quick connection and leak-resistant installation. The press-operated stopper opens and closes by foot, while the faceplate supplies a finished overflow cover.
Limitation: This is a complete bath waste assembly, not a PVC elbow. Choose it only if the drain and overflow components are part of the repair.
Buying Guide
What size tub drain elbow do I need?
Match the fitting to the measured pipe and the existing connection. The products listed here include 40 mm, 1-1/2-inch, and 3-inch options; these are not interchangeable by assumption. Check whether the connection is threaded, slip-fit, or clamp-on, and compare the product specifications with the part being replaced.
Should I choose an elbow, adapter, or repair kit?
Choose an elbow when the pipe needs a direction change. Choose an adapter when you need to connect different drain components, such as the Westbrass fitting for a tub without an overflow. Choose a shoe-pipe kit or waste assembly when the damaged part is part of a larger tub drain system.
Does the fitting need to be PVC?
Confirm both the material and the connection method required by the existing plumbing. The options include PVC, ABS, and flexible PVC. Do not select by color alone; compare the listed material, dimensions, and fitting style.
What should I check before installation?
Measure the pipe diameter, identify the fitting type, and check whether the repair involves the tub shoe, overflow, or downstream drain line. A product described for sewer or 3-inch DWV lines may not be appropriate for a tub connection. Follow applicable plumbing requirements for the installation.
Frequently Asked Questions
Is a 40 mm elbow the same as a 1-1/2-inch elbow?
The listings give different measurements. Verify actual pipe and fitting dimensions rather than assuming the parts will connect.
Which option is the closest match for a PVC tub drain elbow?
The 40 mm PVC 90-degree elbow is the only product specifically described as a right-angle PVC fitting for bathtub waste connections. Confirm that 40 mm matches your plumbing.
Can the 3-inch flexible elbows replace a tub drain elbow?
They are described for 3-inch sewer, drainage, and DWV lines. They should not be treated as tub fittings unless the pipe size and application match.
When is a tub waste assembly a better choice than an elbow?
A waste assembly is a better fit when the repair includes the tub drain and overflow components, not just a change in pipe direction.
