Four listings for the GGF 50305 kitchen mixer sit in ThatRenoStore's Kitchen Sink Tap collection. All four publish the same spec block: 210mm spout length, 265mm spout height, 380mm faucet height, WELS 2 Ticks. The chrome is $130.50. The metal gun is $202.50.
That is $72.00, or 55.2%, for a colour.
Three things move a kitchen tap's price in this catalogue: the finish, whether it mixes hot and cold, and whether the spout pulls out. Below is what the live listings say about each. Prices were read off the live product pages on 20 August 2026 and can change.
1. Finish
The GGF 50305 is the clearest case. All four listings publish an identical spec block and differ only in the finish name.
| Listing | Published finish | Price | Over chrome |
|---|---|---|---|
| GGF 50305 CHROME | Brass Chrome | $130.50 | – |
| GGF 50305 BLACK | Brass Black | $191.25 | +$60.75 (+46.6%) |
| GGF 50305 MGOLD | Brass Matt Gold | $202.50 | +$72.00 (+55.2%) |
| GGF 50305 MGUN | Brass Metal Gun | $202.50 | +$72.00 (+55.2%) |
Every one of them publishes Spout Length 210mm, Spout Height 265mm, Faucet Height 380mm, Wels : 2 Ticks.
The GGF 50505 does the same thing. Both of its live listings publish 220mm spout length, 270mm spout height, 350mm faucet height and WELS 2 Ticks. Chrome is $130.50 and black is $191.25, a 46.6% premium on an identical published specification.
The GLP 5915 runs a four-rung ladder with a much narrower spread. It is a pull-out model, and all four listings publish 230mm spout length, 215mm spout height, 430mm faucet height and WELS 3 Ticks.
| Listing | Published finish | Price | Over the base |
|---|---|---|---|
| GLP 5915 SS | Stainless Steel Matt | $157.50 | – |
| GLP 5915 BLACK | Stainless Steel Black | $168.75 | +$11.25 (+7.1%) |
| GLP 5915 MGOLD | Stainless Steel Metal Gold | $180.00 | +$22.50 (+14.3%) |
| GLP 5915 MGUN | Stainless Steel Metal Gun | $180.00 | +$22.50 (+14.3%) |
Top finish to base finish is 14.3% here, against 55.2% on the GGF 50305. Same vendor, same collection, same week.
Then there is the GGF 50805, also G.Ferretti and also in this collection. It is a pull-out mixer publishing 220mm spout length, 200mm spout height, 550mm faucet height and WELS 2 Ticks, and it is $360.00 in Brass Black and $360.00 in Brass Metal Gun. Two finishes, one price.
Chrome is not automatically the cheap rung either. Aalto's AT5156 pull-out mixer is $416.25 in brushed steel, $495.00 in chrome and $555.00 in matte black. Chrome sits in the middle of that ladder.
So inside one collection, on one vendor's shelf, the finish premium runs from nothing to 55.2%. It is a per-model question, and the published spec block is where you check it.
2. Cold tap or mixer
The lowest-priced live tap in this collection is the QNTL-1613-C at $45.00. Its description reads "Cold Water Faucet". One inlet, cold water only. It is a real $45.00 tap and it will never give you hot water.
The same vendor's cheapest live mixer, the QNTL-1203 at $126.00, publishes "Hot & Cold Water Faucet".
The title does not always tell you which one you are looking at. The GLP 3115 is titled "Kitchen Sink Tap - Chrome" and priced at $70.88, and its own description reads "Kitchen Sink Cold Tap". Read the description line, never the title.
3. Pull-out or fixed spout
The QNTL-9153-1 and the QNTL-1833 are the clearest pair to compare. Both are NTL, both chrome, both stainless steel, both described as a "Hot and Cold Water Faucet". The two listings differ by exactly one published line: the QNTL-1833 adds "Pull Out Sprayer Design".
That line is $120.00. The QNTL-9153-1 is $152.00 and the QNTL-1833 is $272.00, a 78.9% increase.
Further up the range, the finish premium stacks on top of the pull-out premium. The QNTL-1883 (BN) in brush nickel is $382.00 and the QNTL-B1883 in black is $414.00.
What the three drivers cost, side by side
| Driver | Evidence in this collection | What it costs |
|---|---|---|
| Finish | GGF 50305, four listings, identical spec block | 0% to 55.2% |
| Cold tap to mixer | QNTL-1613-C $45.00 to QNTL-1203 $126.00 | +$81.00 |
| Fixed spout to pull-out | QNTL-9153-1 $152.00 to QNTL-1833 $272.00 | +$120.00 (+78.9%) |
Reading a listing before you pay for it
- Compare the published spec block, not the title. Two listings carrying the same model code and the same dimensions are the same tap in a different colour.
- Check the finish premium on your specific model. It ranges from 0% to 55.2% inside this one collection.
- Confirm hot and cold. "Cold Water Faucet" and "Hot and Cold Water Faucet" are the exact phrases these listings use.
- Settle the pull-out question before you compare prices. It moves the number more than any finish here does.
- Check the WELS tick rating while you are in there. It is published on the G.Ferretti listings and it affects your water bill for as long as you own the tap.
If you are choosing the sink at the same time, our kitchen sink buying guide covers cut-out size and steel thickness, which are the two figures that decide whether a sink drops into your counter at all. The same read-the-spec-block habit applies to other categories: our 707 vs Ariston storage water heater comparison does it for tank size, warranty and price.
Common questions
Does a black or gold kitchen tap cost more than a chrome one?
Usually, but not always, and the size of the gap varies a lot by model. On the GGF 50305 the metal gun and matt gold listings are $202.50 against $130.50 for chrome, a 55.2% premium on an identical published spec block. On the GGF 50805 the black and metal gun listings are both $360.00, so there is no premium at all. Check the specific model rather than the brand.
Is a cold-water-only kitchen tap cheaper than a mixer?
Yes. The QNTL-1613-C, described as a "Cold Water Faucet", is $45.00 and is the lowest-priced live tap in ThatRenoStore's Kitchen Sink Tap collection. The same vendor's cheapest live mixer, the QNTL-1203, is $126.00 and publishes "Hot & Cold Water Faucet". A cold tap has one inlet and cannot deliver hot water.
How much does a pull-out spout add to a kitchen tap's price?
On the closest comparison in this collection, $120.00. The QNTL-9153-1 at $152.00 and the QNTL-1833 at $272.00 are both NTL, both chrome, both stainless steel and both described as a "Hot and Cold Water Faucet". The QNTL-1833's listing adds one line the other does not have: "Pull Out Sprayer Design". That is a 78.9% increase.
How can I tell whether two kitchen tap listings are the same tap in different colours?
Compare the published spec block rather than the title. The four GGF 50305 listings each publish Spout Length 210mm, Spout Height 265mm, Faucet Height 380mm and Wels : 2 Ticks, and differ only in the finish name and the price. Where two listings share a model code and every published dimension, the finish is the difference.
What does "WELS 2 Ticks" mean on a kitchen tap listing?
WELS is Singapore's Water Efficiency Labelling Scheme. More ticks means a more water-efficient rating. The G.Ferretti kitchen taps in this collection publish either 2 Ticks or 3 Ticks in their descriptions: the GGF 50305 and GGF 50505 publish 2 Ticks, and the GLP 5915 and GLP 3115 publish 3 Ticks.
Can I trust a kitchen tap listing's title to tell me what it is?
Not on its own. The GLP 3115 is titled "Kitchen Sink Tap - Chrome" and priced at $70.88, while its own description reads "Kitchen Sink Cold Tap". The description line carries the operating type, the dimensions and the WELS rating, so it is the field to read before comparing prices.
