Enhon 2 Set Tub Spout Diverter Repair Kit, Includes 2 x Diverter Valve Stems, 2 x Cup Seals and 2 x Gates, Bathroom Shower Bathtub Leaky Faucet Repair Replacement Parts

What this kit is and why I tried it

A tired tub spout diverter is one of those small failures that makes every shower feel worse. In my case, pulling the knob on my spout barely nudged water toward the showerhead—most of it still dumped into the tub. Rather than swap the entire spout, I tried the Enhon tub spout diverter kit. It’s a simple pack with two metal stems, two plastic gates, and two rubber cup seals designed for straight‑edged diverter spouts. The promise is straightforward: replace the wear parts, restore the seal, and get your shower back.

I installed one set in an older, standard pull‑up diverter spout and kept the second as a spare. Here’s how it went and what stood out.

Installation: doable for DIYers with a couple of tips

On my spout, the diverter uses a lift rod that snaps onto the stem via two small tabs. The kit’s sequence—spread tabs, remove old gate/parts, drop in cup seal, insert new gate, reattach lift rod—tracks with reality. A few practical notes from my bench:

• Tools I used: small flathead screwdriver (to ease off the lift‑rod tabs), needle‑nose pliers, a pick, and plumber’s silicone grease.
• Prep matters: mineral buildup inside the spout can keep a new gate from seating. I soaked the spout nose in warm vinegar for 10 minutes and brushed the cavity clean before the new parts went in.
• Cup seal orientation: match the orientation of the old seal. The “cup” should face the flow it’s meant to block; if you flip it, you’ll get poor sealing and lingering tub flow.
• Grease sparingly: a thin film of silicone grease on the cup seal and the sliding surfaces of the gate makes the action smoother and helps the seal seat.
• Don’t pry the tabs too far: the lift rod’s tabs can fatigue if you spread them wide. A little tension is enough to slip the rod off and on.

Actual install time was under 15 minutes including cleanup. If you’ve never opened a tub spout, I’d budget 30 minutes and watch a quick how‑to first. The kit doesn’t include printed instructions in my box, but the parts are intuitive once you see the old ones.

Fit and compatibility: “universal” with real‑world caveats

The kit is marketed to fit most standard straight‑edge tub spouts. In practice, compatibility hinges on your spout having:

• A rectangular, straight‑sided gate cavity (not a rounded or proprietary profile).
• A lift‑rod interface that can snap onto the stem’s tabs.
• Enough depth for the provided gate and cup seal stack-up.

On my generic spout, everything lined up correctly. The stem length was right, the gate slid smoothly, and the cup seal seated without trimming. That said, not all diverter spouts are created equal. Some branded models use unique gate shapes or stem linkages, and some tapered spouts don’t use this style at all. If you’re unsure, pull your spout and measure the old gate’s width/height and the stem’s engagement points. If your old gate isn’t rectangular with straight edges, this kit likely won’t fit.

One minor oddity: the listing references an oil‑rubbed bronze finish. These parts sit inside the spout and aren’t visible, so finish isn’t a factor. The metal stems in my kit had a darkened appearance, but it’s purely cosmetic.

Build quality and materials

For a small repair kit, materials matter. Here’s what I noticed:

• Stems: the metal stems feel rigid and resist flexing under the lift‑rod force. They’re the part that takes the repeated mechanical load, and these seem up to it.
• Gates: the plastic gate is sturdy and molded cleanly. Edges are straight, which is crucial for a tight seal against the spout walls.
• Cup seals: the rubber feels dense and resilient, not chalky or brittle. I couldn’t deform the lip easily with a fingernail, a good sign for longevity.

Nothing in the kit feels cheap, and tolerances were tight enough that I didn’t have to fuss with shimming or sanding.

Performance: noticeable improvement, realistic expectations

Before the swap, my shower was starved—maybe half the flow was making it to the showerhead. After installing the kit, I’d estimate 90–95% of the water was diverted upstairs. Shower pressure improved immediately, and the lift knob action became crisp instead of gummy.

Two realities to keep in mind:

• A tiny dribble from the spout during shower use can be normal, even with new internals, depending on your spout’s internal casting and water pressure. You’re aiming for a strong majority of flow to the shower, not an absolute zero.
• If you still get significant tub flow after a correct install, the spout body might be pitted or warped, preventing the cup seal from fully mating. At that point, replacing the entire spout is usually the right move.

In my case, the seal is tight and consistent after several weeks of use. The gate slides without sticking, and the lift rod stays aligned with the stem.

What I liked

• Straightforward install with basic tools; the parts interface the way you expect.
• Noticeable recovery of shower flow and better knob feel.
• Two complete sets in the box. Keeping a spare is handy, or fix two bathrooms for the cost of one.
• Solid material choices: metal stem, robust plastic gate, quality rubber seals.

What could be better

• Compatibility isn’t truly universal. It’s suited for straight‑edged, gate‑style diverters; proprietary spouts may not fit.
• Instructions are minimal. A clear diagram showing cup seal orientation and stem/tab engagement would help first‑timers.
• The “finish” callout is confusing for parts that live inside the spout.

Tips to get the best result

• Clean the spout cavity thoroughly. Debris or scale will compromise the seal.
• Test‑fit without the lift rod first. Make sure the gate moves freely and the seal seats before you button up.
• Grease, don’t glue. Use plumber’s silicone grease on moving surfaces and seals; avoid petroleum products that can degrade rubber.
• Expect a small trickle. Judge success by improved shower flow, not absolute silence from the spout.

Value

Given the price and the fact that you get two complete sets, the value is excellent. A full spout replacement costs more and can introduce fit challenges at the wall or stub‑out. If your spout body is sound, this kit is a cost‑effective fix that extends its life meaningfully.

Who it’s for

• DIYers comfortable with a screwdriver and pliers who have a standard, straight‑edge gate‑style diverter spout.
• Renters or homeowners wanting to avoid swapping the entire spout.
• Anyone chasing better shower pressure caused by a worn diverter.

Who should look elsewhere:

• Owners of proprietary or non‑gate diverter spouts (some brand‑specific spouts, tapered bodies, or unusual linkage styles).
• Those with heavily corroded or pitted spout interiors; a new spout will seal better than new internals in a damaged cavity.

Bottom line

The Enhon tub spout diverter kit did exactly what I needed: it restored function to a sluggish diverter and brought back strong shower flow, without replacing the whole spout. Installation is approachable, the parts feel well made, and the two‑pack sweetens the deal.

Recommendation: I recommend this kit to anyone with a straight‑edge gate‑style diverter spout who wants a quick, inexpensive repair. Check your spout’s internal geometry before buying, clean the cavity thoroughly, and pay attention to cup seal orientation. Do that, and this little kit punches well above its weight.
