The answer before the details
Tank models let you pour in clean water; faucet-fed models use a compatible tap connection. Both still need a drain route, power and suitable space. Choose the daily filling and sink-access routine first, then compare exact models.

Start with how you want to use your sink
A tank model lets you supply water by filling its reservoir. A faucet-fed model takes its supply through a compatible connection. Neither description tells you everything about installation: both need a permitted way to drain, access to power and the space required by their instructions.
| Your priority | Start here |
|---|---|
| Keep the supply tap available | Explore a model with a built-in tank. Check how you will reach the fill opening. |
| Avoid carrying refill water | Explore faucet supply. Verify the tap before treating the connection as simple. |
| Fit below a low cabinet | Compare exact body heights and operating clearances; tank versus faucet is not a size guarantee. |
Try the routine without buying anything
Stand at the spot you would use. Pretend to load breakfast dishes, refill a tank, open the door and unload into the cupboard. Then imagine someone else needing the sink while you cook. These small movements reveal whether your shortlist fits your household better than a long feature list does.
For a tank, consider where a filling jug would travel and whether you can reach the opening comfortably. Do not assume you can slide a heavy machine forward every day. For a faucet model, look at the exact tap rather than buying a collection of adapters and hoping one works.
Six models, two water-supply routines
Tank or faucet describes how water enters the machine, not which temperature it needs. Before choosing a hookup, check our model-by-model hot or cold water guide for HAVA, COMFEE, Danby and BLACK+DECKER supply instructions.
HAVA R01, HAVA R09 and COMFEE CDC17P2AWW offer tank filling. Danby DDW631SDB, COMFEE CDC22P2AWW and BLACK+DECKER BCD6W belong on a faucet-supply shortlist. The COMFEE names are particularly easy to confuse: CDC17 and CDC22 describe different appliances, not merely different colors.
Read the COMFEE tank-model review or COMFEE six-place-setting review for the differences that need checking before you buy.
The R09 review explains its softener and salt upkeep. The BCD6W review covers its documented 10-inch plate limit and conflicting dimensions. Neither addition removes the need to check the exact appliance instructions.
Make one choice, then narrow the models
Write your non-negotiable first: “keep the tap free,” “avoid manual filling,” or “fit this particular opening.” Then use the model buying guide to choose which review to read. If faucet fit is still uncertain, resolve that before spending money.
A tank is not a promise of a completely hose-free kitchen. Likewise, a compatible faucet does not settle counter clearance, hose routing or loading space. The installation manual remains the final check for your exact appliance.
