A basin tap looks like one of the simpler things to order online, and it usually is, until it arrives and doesn't fit the basin, or the spout is too short, or the finish doesn't match anything else in the room. Here are the mistakes that come up most often, and how to check for each before ordering.
1. Not checking hole count
Basins are drilled for either a single tap hole or three holes (for a widespread three-piece set), and a tap bought for the wrong configuration simply won't mount. Before ordering, count the holes already in your basin, or check the hole spec on the new basin if you're replacing both together. It is one of the easiest mistakes to make, and one that can't be worked around at installation.
How do I know if my basin needs a single-hole or three-hole tap?
Count the pre-drilled holes in your existing basin, or check the hole spec listed on a new basin if you're replacing both at once. Get the count wrong and the tap simply won't mount.
2. Ignoring WELS rating
Every tap in the catalogue is listed with a WELS tick rating. The G.Ferretti GLP 5317A at $141.75 is rated 3 ticks. The GLP 3917 is rated 2. A higher tick rating means better water efficiency, which matters over years of daily use. The rating sits on every listing, so check it before you order.
How many WELS ticks should I look for on a basin tap?
Use the ticks to break a tie between two taps you already like the look of. G.Ferretti's GLP 5317A is rated 3 ticks and the GLP 3917 is rated 2, and every listing here prints the number, because PUB requires the label on the water fixtures we sell. On a tap that runs several times a day, one tick of difference is water you keep paying for long after the price difference stops mattering.
3. Wrong spout height or length for the basin
A tap with too short a spout can splash against the basin wall instead of the bowl; too long, and it can overshoot into the counter. Listings specify spout length and height individually. The GLP 5317A lists a 114mm spout length and a 100mm spout height, for example. Match these against your basin's own dimensions, particularly for a vessel or above-counter basin where the geometry is less forgiving than a standard undermount.
4. Mismatching finish across fittings
Gunmetal, chrome, matte black and gold are all live finish options across the catalogue's brands (Aalto, NOBEL, G.Ferretti). A tap ordered in a different finish from the shower fittings or accessories in the same bathroom is one of the more visible mismatches in a finished renovation. It's an easy one to avoid: check the finish names match exactly, not just "looks similar" in a product photo, before ordering everything separately.
Can I mix tap finishes in the same bathroom?
You can, but it's a visible design choice rather than an accident. Check finish names match exactly if you want a uniform look across taps, shower fittings and accessories bought separately.
5. Taking a vague spec at face value
Marketing language like "durable construction" appears on plenty of listings and isn't a substitute for checking what a tap is actually made of. Where a listing states material specifics, like NOBEL's NN-331-SS specified as SUS304 stainless steel, that's a concrete, checkable spec. If a listing doesn't state a material, ask us.
