A single product concept can easily expand into many SKUs. A different color becomes one SKU, an additional water mode becomes another, and different combinations of features quickly turn one product into what appears to be a large range.
The more important question is whether those SKUs actually cover different needs.
Die Waterfall Kitchen Faucet is a useful example because this category can generate numerous variations through water modes, functional combinations and finishes.
Each SKU Should Represent a Meaningful Choice
If a basic waterfall kitchen faucet and a 3 mode kitchen waterfall faucet provide genuinely different water functions for different uses, keeping them as separate SKUs makes sense.
But if two models share the same body, functions, installation method and primary application, with only a minor decorative difference, it is worth asking whether that difference justifies managing them as separate SKUs over the long term.
A practical way to evaluate an SKU is to ask:
What would the product range lose if this model were removed?
If removing it would eliminate an important function, a clearly different way of using the faucet, a key finish or necessary price coverage, the SKU has a clear role.
If removing it leaves almost no gap in the range, it may simply be a redundant variation.
More Feature Combinations Do Not Automatically Create a Better Range
The same applies when considering a 4 in 1 waterfall kitchen faucet. The important question is not whether “4 in 1” offers more than “3 mode,” but whether it represents a genuinely different functional level.
If the additional functions provide clear practical value, the model can serve as a higher-configuration option. But if every small feature is combined in different ways and each combination becomes a separate SKU, the range can expand very quickly.
The result is not only more products. It also means more product images, packaging, inventory, product pages and internal management.
For multi-mode faucets, functional differences should also be verified through actual samples. Mode switching, return action, water landing position, splashing and the performance of related moving parts should create a stable and noticeable difference in use. A higher number of functions alone is not enough reason to create another SKU.
SKU Depth Should Follow Differences in Demand
There is no fixed answer to whether a range should contain five, ten or more SKUs. What matters is the logic behind those variations.
A range can retain a basic functional version, a clearly defined upgrade, important finishes and necessary models for different installation or usage requirements. Variations with only minor differences should be added more carefully.
A mature Waterfall Kitchen Faucet range does not need to include every combination that is technically possible. The value of SKU depth comes from covering enough meaningful choices, not from demonstrating how many variations can be produced.
