Wastes and traps, in the versions that actually fit
Pop-up and push-open basin wastes, and traps to go under them.
Slotted against unslotted. A basin with an overflow needs the first; one without needs the second, and fitting the wrong one leaks into the cupboard rather than failing visibly. A listing that states which is a listing you can order from.
The water seal depth, and whether it dismantles without tools. A shallow seal in a bathroom used twice a week is what dries out and smells.
Pop-up waste · 1 1/4 in stated · slotted, for a basin WITH an overflow · push-open · an unslotted variant offered in the same range
A push-open waste that states its thread AND its overflow type, and points you at the other version if yours is the other kind.
Best for: A conventional basin with an overflow, bought alongside the same range's flat trap.
≈ £10 / 15 €
Trap · flat, space-saving · G 1 1/4 in inlet × 32–40 mm outlet · fits under basins with LESS than 15 cm of clearance — stated · hand-tightened, no tools
The only trap in this catalogue that publishes the clearance it needs — it fits where there is less than 15 cm under the basin.
Best for: A vanity unit with a drawer, or any basin where the cupboard below has already been designed around something else.
