The drain parts offered by VEVOR include freestanding bathtub drain rough in kits with two brass tailpipes and a material-matched adapter, available in both PVC and ABS configurations. Whether you are installing an island bathtub, a floor-mounted bathtub, or a new freestanding bathtub, VEVOR's bathtub drain kits include all the essential parts for a thorough drain rough-in, so you don't have to source parts from other vendors.
Do you require a complete drain rough-in kit to connect to your current subfloor drain for installing a freestanding bathtub? It requires an appropriate material adapter, appropriately sized tailpipes, and a kit designed to work with your current drain infrastructure to connect the drain to a standalone or island tub properly. With everything contained in a single, properly matched kit, VEVOR's drain parts eliminate uncertainty during the rough-in process.
Two freestanding tub drain kits, one with a PVC adapter and the other with an ABS adapter, are currently available in VEVOR's drain parts category. They are both designed as full bathtub drain rough-in options. The most crucial step before making a purchase is to understand what each kit contains and how its parts work together.
Compared to a typical alcove tub drain installation, a freestanding bathtub drain rough-in is more complicated. The drain outlet on the tub base must connect to the floor drain in the sub-floor below via a vertical or angled pipe run that is completely hidden beneath the tub because a freestanding tub sits freely on the bathroom floor rather than against a wall. The rough-in kit needs to bridge the gap neatly, accounting for small positional variations between the floor drain's center and the tub's drain outlet.
For this situation, VEVOR has created standalone tub drain kits. To accommodate varying floor depths and tub clearances, each system includes two brass tailpipes that connect the tub base to the sub-floor adapter. Because bathroom flooring varies in thickness, a fixed-length single-pipe assembly would require on-site cutting and modification, making the flexible dual-pipe layout a practical option. The package provides the installer with a proper starting point for the most common floor-depth scenarios, eliminating the need for custom pipe cutting during installation by including two tail pipes of specified lengths.
The PVC freestanding tub drain kit ($68.99) connects the brass tailpipe assembly to the building's existing drain, waste, and vent system via a PVC adapter. Since PVC is the most commonly used drainpipe material in homes built or remodeled after the mid-1980s, most modern residences should use it. Solvent-weld cement is used to join the PVC adapter to standard PVC drain lines, forming a permanent, watertight bond that resists vibration and thermal expansion over time.
Without specialized skills, the PVC adapter in VEVOR's bathtub drain kit is sized to fit the tailpiece of the brass pipe assembly. It uses a compression-style or threaded connection, keeping the interface between the brass and plastic components leak-resistant. The entire vertical connection between the freestanding tub drain outlet and the horizontal PVC drain line beneath the subfloor is covered by the complete system, which includes two brass tailpipes and the PVC adapter. This feature is all that is needed for the rough-in stage of installing a freestanding bathtub in a bathroom with PVC plumbing, making it a truly complete solution rather than a partial assembly that requires additional parts.
The configuration of the ABS freestanding tub drain kit ($68.99) is the same as that of the PVC version, except it requires an ABS adapter rather than a PVC one. Homes constructed before the widespread use of PVC, especially in most of North America during the pre-1980s residential construction era, often use ABS drain pipe. It is important to have a kit with the appropriate material adapter for your current drain system, as most plumbing regulations do not allow mixing ABS and PVC without a specific transition cement.
A standard ABS solvent weld cement connection, the same technique used throughout the current drain system, is made possible by using the ABS adapter from VEVOR's ABS bathtub drain rough in kit with an ABS drain line. This feature eliminates the need for a material transition joint, which could be non-compliant or structurally weaker. Purchasing the PVC version and modifying it adds needless complexity and perhaps compliance risk for homes with ABS drain infrastructure. Customers can easily choose the type that best suits their drain system without compromising, because VEVOR offers both material options at the same price point.
The tail pipes in both VEVOR drain kits are made of brass rather than plastic, a deliberate choice that enhances long-term performance. In the segment of the pipe that is continuously wet and exposed to body oils, cleaning agents, and soap residue, brass is far more resistant to corrosion from drain water than ABS or PVC. Additionally, it has a stronger thread than plastic, which is crucial at the junction where the tub drain shoe and tail pipe attach. This joint needs to stay leak-free even when a filled bathtub presses down on the drain outlet.
The use of brass tail pipes with a plastic adapter at the subfloor connection, where the join to the existing drain pipe must be made with compatible materials, and brass, where mechanical strength and corrosion resistance are most important, demonstrates a practical engineering approach to bathtub drain parts. This combination eliminates the need for a totally brass installation, which would be needlessly costly for the subfloor connection. It provides the kit with durability at the tub end and code-compliant compatibility at the drain-line end.
It is important to consider code compliance, installation technique, and compatibility with the building's current plumbing system when choosing the material for bathtub drain parts, in addition to durability considerations.
The drain material that is already in place beneath your bathroom floor is the primary practical distinction between the PVC and ABS drain kit adapters. It is most likely PVC if you pull a piece of your current drain pipe and it is white or cream. It is most likely ABS if it is dark gray or black. Because the adapter must be solvent-welded to the existing pipe with the appropriate cement, the decision between the two materials is based solely on what is already in the building. Both materials function similarly in residential drain applications.
The majority of building inspectors and residential plumbers require that drain connections be constructed using the same material as the existing system or, if materials need to be joined, with a clearly marked transition cement. Purchasing the appropriate kit from VEVOR, such as the ABS freestanding tub drain kit or the PVC bathtub drain kit, eliminates any material mismatch at the adapter connection and ensures a simple installation for any plumber or self-assured do-it-yourselfer performing the rough-in work.
VEVOR's drain parts kits are specifically compatible with three types of bathtub installations: freestanding, floor-mounted, and island bathtubs. The installation challenge is the same for all three: unlike alcove tub installations, the drain outlet links to the subfloor drain via a vertical pipe run rather than a wall. Across these three installation styles, VEVOR's kits' flexible dual-tail-pipe arrangement allows for height flexibility between various tub base heights and floor structures.
When a homeowner replaces an old freestanding tub with a new one, VEVOR's bathtub drain rough in kit allows the connection to be properly updated when the new tub's drain outlet position differs from the previous one. Without the need for subfloor alterations, the two-pipe configuration provides sufficient adjustment range to accommodate small positional variations. The package creates the necessary rough-in connection from scratch for new construction when a freestanding tub is installed for the first time, ensuring the drain is correctly aligned and sealed before the tub is positioned and the completed piping is attached.
For a reasonable price of $68.99, R's drain parts offers plumbers and homeowners a complete bathtub drain rough in kit in the appropriate material for any installation: an ABS freestanding tub drain kit or a PVC bathtub drain kit, each with two brass tailpipes and a matching adapter. Both kits provide all the components required for a safe drain connection and are compatible with freestanding, floor-mounted, and island bathtubs.

The material of the drain adapter included with each kit varies. Standard PVC solvent cement is used to attach the PVC kit to existing PVC drain lines. Using ABS cement, the ABS kit attaches to the current ABS drain lines. Select the model that corresponds to the material of the drain pipes in your house.
Island, floor-mounted, and freestanding bathtubs are all compatible with VEVOR's freestanding tub drain systems. The subfloor drain connection technique is the same for all three, and the dual-brass-tailpipe layout is adjustable to meet differences in tub base height and floor depth.
At the connection between the tail pipe and the tub drain outlet, which is constantly wet and under load from a filled tub, brass offers exceptional thread strength and corrosion resistance. The mix of brass and plastic provides material compatibility at the subfloor connection and strength where it matters most.
VEVOR's bathtub drain rough-in kits include the two brass tailpipes and the drain adapter necessary for the sub-floor connection. The tub's drain shoe and overflow assembly, solvent-weld cement that matches the material of your adapter, and any fittings needed to connect to your horizontal drain line below the floor are also necessary.
You should not do that. Local plumbing codes may not permit solvent-welding PVC to ABS, as it requires a specific transition cement. A standard, code-compliant connection using the same type of cement is guaranteed when the ABS kit is used with an ABS adapter on an ABS drain system.
