People are only just realising what the cap on your kitchen sink can be used for


Unseen Kitchen Sink Feature Leaves Homeowners Surprised

Many homeowners are expressing astonishment after discovering the purpose of a frequently overlooked component of standard kitchen sinks: the small cap.

Typically located between the draining board and the basin, this round cap, approximately 6cm in diameter, offers a practical function that often goes unnoticed. TikTok user and DIY enthusiast Shauna O’Connor shared her own discovery in a video, aiming to inform others about this useful feature.

TikTok Video Exposes Little-Known Sink Hack

“Apparently, many of you were unaware of this sink tip,” O’Connor stated in her video. “I am replacing my dish soap dispenser, which is three years old, quite worn, and leaking. While doing so, I realised that many are unaware that this cap on your sink is removable.”

O’Connor’s video footage from inside her under-sink cabinet showed a soap dispenser already installed. After detaching the cap from the sink top, she explained, “You can fill the opening [left by the removed cap] with a dispenser.”

Effortless Soap Dispenser Integration

Showcasing an example available on Amazon for £8.99, O’Connor detailed the simple process: “Once you acquire one, just pop the cap off. Installation is straightforward and quite affordable. Mine has lasted three years.”

After screwing in her new dispenser, Shauna demonstrated its use by dispensing soap onto a cloth, declaring, “I really appreciate this neat trick. It’s so convenient.”

In an accompanying caption, she added, “And it eliminates clutter from the countertop! Don’t keep this a secret, share it with a friend.”

Viral Tip Resonates with Millions

Since O’Connor shared her video, it has garnered significant attention, with 3.7 million TikTok users viewing the advice. One user commented, “I just checked, and I have that cap on my sink. I’m going to get one of these, thanks for this. I have learned so much watching TikTok.”

Another user admitted, “Wow, I had no idea, thank you.” A third confessed, “So that’s what that is on my sink. I have been wondering for years.”

Additional Advice and Alternative Perspectives Emerge

Other TikTok users contributed further insights. One person advised, “Before purchasing, check the space beneath your sink. Sometimes the cabinet frame can obstruct installation.”

Another user offered a helpful suggestion: “Instead of the small refillable bottle, you can use a tube that connects directly from the sink pump to a large dish soap bottle in the cabinet below. This is much easier than refilling the small bottle.”

Contrasting Views on Cap’s Original Purpose

However, some users offered differing perspectives on the cap’s intended design. “The hole is for the faucet/tap if the sink is installed in reverse,” one TikTok user clarified.

Another individual concurred, stating, “It’s actually for a tap/faucet if the sink is reversed. The dispenser is a retrofit. If it were intended for a dispenser, it wouldn’t be positioned there.”
