Open the cupboard under almost any vanity or kitchen sink and the trap is sitting right in the middle, with a big notch cut out of the shelf to clear it. Space saver traps fix that by moving the trap and waste up against the back of the cabinet, so the shelf only needs a small cut-out and the cupboard is actually usable. They're one of the simplest upgrades in a bathroom or kitchen renovation.
Vanity: Box Trap & Vanity Space Saver (40mm)
The Art Box Trap & Vanity Space Saver, 35122 ($31.85) is a compact 40mm box trap designed to sit flat against the back of the vanity. The benefits:
- More shelf space — minimal footprint, so drawers and shelves aren't fighting the trap.
- Cleaner look — flat to the back of the cabinet with fewer dust traps.
- Easier to clean around.
It's a good match for vanities with drawers, where a conventional trap often forces a cut-down top drawer or a U-shaped drawer box.
Kitchen: Kitchen Sink Space Saver (50mm)
The Art Kitchen Sink Space Saver does the same job under the sink, at 50mm, with compression fittings for a quick install:
| Version | SKU | Price |
|---|---|---|
| Single bowl | 35221 | $19.75 |
| Double bowl | 35222 | $50.55 |
It frees up the most-used cupboard in the kitchen by minimising the shelf cut-out, leaving room for bins, cleaning products or a pull-out drawer.
Choosing the right one
- Basin or vanity: 40mm box trap (35122).
- Single bowl kitchen sink: 35221.
- Double bowl kitchen sink: 35222 — or for a conventional setup, see the double bowl connectors in the range.
- Dishwasher on the sink waste? Plan the dishwasher drain connection at the same time so the space saver isn't undone by a hose looping across the cupboard.
Before you install
- Check the waste height. The wall waste (or floor waste) has to suit where the trap outlet ends up at the back of the cabinet. On a renovation, set the wall connection height before the wall is closed.
- Measure the cabinet depth and back panel position so the trap sits flat against it.
- Check compliance. Refer to the manufacturer's spec sheets for WaterMark licence and applicable standards; installation and drainage must be done by a licensed plumber in line with the relevant Australian Standards.
Other trap problems
If the issue is alignment rather than space, our Twister combination trap post covers rotating nipples for awkward connections. For bath wastes that don't line up, see flexible bath waste connectors. Choosing a vanity at the same time? Vanity tap-hole positions explained helps with the top.
