Oatey 46000P PVC Universal Freestanding Tub Drain Kit

The Verdict

If you’re staring at a freestanding tub drain hole and a plumbing wall that’s already closed up, the Oatey 46000P is the kit that saves your weekend. This isn’t a glamorous purchase — it’s the difference between a working tub and a call to a plumber who charges $150 just to show up. With 229 ratings and a 4.6-star average, it’s clearly doing something right for DIYers and pros alike.

What you actually get

As shown in the product image, the kit includes the drain body, overflow elbow, tee fitting, and all necessary gaskets and washers. The key selling point is the universal design — the adjustable extension range accommodates most freestanding tub configurations without custom cutting. For a kit that retails in the budget-friendly range, you’re getting everything needed to complete the rough-in, minus the trap arm and tubular pipe that runs to your wall stub-out.

Performance and build quality

The all-PVC construction is the smartest thing Oatey does here. Unlike chrome-plated brass kits that corrode or react with harsh chemical drain cleaners over time, PVC shrugs off everything you throw at it. The slip-joint connections are straightforward, and the gaskets seat well when you hand-tighten them properly.

One thing to note from my research: buyers consistently mention the importance of dry-fitting everything before gluing. As one verified purchaser put it, “I test-fitted the whole assembly twice before cementing anything — saved myself from a crooked drain.” That’s solid advice. The PVC threads are functional but unforgiving if you cross-thread them, and once you commit with primer and cement, there’s no going back.

What buyers consistently praise

The universal fit is the star here. Multiple reviewers noted it worked for tubs they assumed would need a custom solution. One said, “I have a cheap Amazon freestanding tub and this drained perfectly — zero leaks on the first test.” Another appreciated that it included the overflow plate, which many competing kits omit.

The value proposition is also strong — this kit runs significantly less than buying components separately, and the quality is consistent with what you’d expect from a brand that’s been in the plumbing game since 1916.

Where it falls short

Honest assessment: the instructions are minimal. If you’re not familiar with basic drain rough-in, you’ll want to watch a YouTube tutorial before starting. The slip-joint nuts are also easy to over-tighten, which can crack the PVC or deform the gasket — hand-tight plus a quarter turn is the sweet spot.

Also, while it’s called “universal,” it’s not a magic bullet. If your freestanding tub has an unusually deep base or a non-standard overflow position, you may still need an extension piece. Measure your tub’s dimensions before ordering.

Who should buy this

• DIY homeowners installing a freestanding tub in a new bathroom or remodel
• Contractors who want a reliable, code-compliant drain kit they can stock on the truck
• Anyone replacing a corroded or leaking drain on an existing freestanding tub

Skip it if you need a full tubular drain kit that connects to the trap — you’ll need to buy the trap arm and p-trap separately.

FAQ

Q: Does this kit work with any freestanding tub? A: It fits most standard freestanding tubs, but measure your overflow height and base depth first. The adjustable extension handles typical variations, but unusually deep tubs may need extra pieces.

Q: Do I need to glue the connections or are they compression fittings? A: The slip-joint connections are hand-tightened, but the main drain assembly uses PVC primer and cement for permanent joints. Dry-fit everything first.

Q: Is this code-compliant for residential use? A: Yes, it meets standard plumbing codes for residential bathroom drains. PVC is approved for drain, waste, and vent applications in most jurisdictions.

The verdict

The Oatey 46000P earns the 4.6 stars it carries. It’s a well-made, thoughtfully designed kit that solves the most common freestanding tub drain problem at a fair price. The minor quirks — minimal instructions, easy-to-cross-thread fittings — are manageable for anyone with basic DIY competence.

Buy it if: You’re installing a freestanding tub and want a complete, reliable drain assembly without paying plumber markup.

Skip it if: You’re not comfortable with basic PVC plumbing work, or your tub has non-standard dimensions that need custom fitting.

Rating: 4.6/5 — a solid, dependable workhorse that gets the job done right the first time.
