1 × expandable under-sink shelf frame
Shelf boards in the quantity selected: 3, 4, 6 or 8

Dimensions

An expandable under-sink storage shelf with a stainless-steel frame and plastic shelf boards. The supplier lists an adjustable frame width of 50–90cm and a depth of 25cm. Choose the tier and board configuration before checking your cabinet.

Compare the four configurations

Variant	Listed base width	Total height
Single tier – 3 boards	52.5cm	38.5cm
Single tier – 4 boards	68.5cm	38.5cm
Double tier – 6 boards	52.5cm	50cm
Double tier – 8 boards	68.5cm	50cm

The double-tier options list 23.5cm between tiers. The frame’s stated extension range and the selected configuration’s base width are different measurements; check both when planning a narrow cabinet.

Arrange the boards around the waste pipe

The modular board sections can be repositioned to leave a gap, but the frame legs, pipe and cabinet opening still need to clear each other. This shelf stays in place; it is not a pull-out drawer.

Included: one shelf frame and the selected three, four, six or eight boards. Easy assembly is supplier-listed. A per-shelf load rating is not specified; do not infer one from the material.

For a fixed frame with a moving lower tier, compare the two-tier pull-out drawer organiser. Use the under-sink measuring guide before choosing.

What is the difference between the four variants?

Two axes: number of tiers (single or double) and number of shelf boards (which controls the base width). The 3- and 6-board options have a 52.5 cm base; the 4- and 8-board options have a 68.5 cm base. Single-tier is 38.5 cm tall; double-tier is 50 cm with 23.5 cm of clearance between the two tiers.

How does the expansion work?

The supplier lists an adjustable frame width of 50–90cm. The shelf boards sit on the frame and can be repositioned to leave a gap around plumbing. Check the selected configuration’s base width as well as the extension range, and follow the assembly instructions.

What does "Boards" mean?

The shelf surface is made of individual board sections that sit on the frame, rather than one continuous shelf. More boards = more shelf surface, and importantly, you can pull a board out of the middle to leave a gap for the under-sink waste pipe — the most common reason fixed shelves do not fit under a sink.

How do I pick the right size?

Measure your under-sink cabinet width first. Pick 3 or 6 boards (52.5 cm base) if your cabinet is narrower; 4 or 8 boards (68.5 cm base) if it is wider. Pick single tier if cabinet height is tight or the pipes intrude from above; pick double tier if you have enough vertical space to stack two layers (50 cm total height).

What is it made of?

The supplier lists a stainless-steel frame with plastic shelf boards and a black frame finish.

How is this different from your 2-Tier Pull-Out Under-Sink Rack?

The pull-out rack is a fixed-width rack on sliding tracks that pulls forward to access the back of the cabinet. This shelf does not slide — it is fixed in place — but its width adjusts to fit the cabinet, and the boards can be rearranged to clear the waste pipe. Different solutions to the same problem: one brings items out, the other adapts around the obstacles.

Does it come assembled?

The supplier lists easy assembly. Follow the supplied instructions for fitting the frame and boards; the product information does not establish which tools are required.

How much weight can each shelf hold?

A per-shelf load rating is not published in the supplied product information. Do not assume a kilogram limit from the frame material or size. Follow the supplied loading instructions and confirm the rating before buying for heavy items.
