Build a Boot Room Bench With IKEA TRONES Units in 7 Steps for 30% More Hallway Storage

Why three TRONES units carry the idea

A single TRONES shoe cabinet measures 51cm wide, 39cm tall, and 18cm deep. It holds four to six pairs, depending on how flat the shoes fold against the tilting front. Two units span about 1.02m; three reach 1.53m before gaps are added.

The bench board needs a small projection at both ends. That makes a run of about 1.2m to 1.5m the practical zone for three units under one continuous plank, with 30mm to 50mm of timber showing past each outside cabinet edge.

The storage arithmetic is the reason the project makes sense. A freestanding hallway bench with an open shelf underneath typically stores six to eight pairs at floor level and takes up 40cm of depth. Three TRONES cabinets store twelve to eighteen pairs in 18cm of wall depth, with the seat placed above that storage volume. The same wall length now works as closed shoe storage and as somewhere to sit. Measured against a conventional bench-plus-rack arrangement, the recovered floor area is where the 30 percent storage gain comes from.

TRONES fronts tilt forward on hinges, so shoes can be loaded and removed without a cabinet door swinging into the corridor. In a passage under 90cm wide, that clearance can matter as much as the pair count.

Steps 1 to 3: find the high point, set the rail, fix the wall line

Find the highest point along the floor where the cabinets will sit. Hallway floors are rarely level, and a bench shows every millimetre of slope across a 1.5m run. Put a 1.2m spirit level along the skirting line, mark the high point, and use that mark as the datum for every cabinet height reference.

TRONES hangs from a back rail supplied in the flat pack. The rail screws to the wall, then the cabinet clicks onto it. Because of that system, accuracy comes from one clean horizontal line across the wall.

A comfortable bench height runs from 42cm to 48cm to the top of the seat. Work backwards from the height you want: subtract the plank thickness, then subtract the 39cm cabinet height, then mark where the rail screws land. For a 45cm seat with a 38mm plank, the rail usually sits about 4cm to 5cm below the cabinet top edge, depending on the rail design in the pack.

Mark a continuous pencil line across the three rail positions with the spirit level. Drill on that line.

In plasterboard, the rail needs timber studs or heavy-duty cavity fixings. A loaded bench with a seated adult can put 80kg to 120kg of downward and pull-out force through those screws. A stud detector and 50mm screws into timber studs give a stronger daily seat fixing than plasterboard plugs.

Hang all three cabinets and check their top edges with the level. If one unit reads low, shim behind its rail before the plank goes anywhere near the cabinets.

Step 4: choose and cut the plank

A 38mm pine stair tread or a glued pine panel both work for the seat; the stair tread comes pre-rounded on one edge, which suits the front of a bench. Solid oak at 27mm looks better and costs three to four times more for a 1.5m length. Whichever timber you choose, cut the board to the total cabinet run plus both end projections, because 30mm to 50mm of overhang at each outside edge makes the top read as a deliberate seat.

Sand the cut ends to the same grit as the faces, working up to 180 grit. Pine end grain drinks finish and shows every saw mark, so the cuts deserve the same attention as the top surface. The TRONES tops provide contact area without serving as a full structural fixing surface on their own; the plank is the part a person actually sits on, and its rigidity carries the load between the three support points.

Step 5: finish the timber for hallway use

Hallways bring wet coats, dripping umbrellas, and grit from boots, so the bench finish works harder here than the same plank would in a bedroom. Bare pine left raw will grey and stain within a season near a front door. Two coats of a hardwax oil such as Osmo Polyx-Oil give a surface that resists water spotting and can be repaired in patches without sanding back the whole board.

Apply the first coat thinly along the grain with a cloth. Leave it for the full drying time given by the manufacturer, then key the raised grain lightly with 320 grit before applying the second coat.

A polyurethane varnish gives a harder, glossier film. It chips at edges, and a chipped area needs the full panel sanded to blend a repair. Oil sinks in and wears gradually, which suits a seat that takes daily contact and scuffs along the front edge.

The TRONES fronts are wipe-clean melamine and need no finish. The only timber in the build is the seat, so all the finishing effort belongs on that one board. Leave the underside unfinished or give it a single sealing coat; it gets no regular wear, and the bracket screws bite better into unsealed wood.

Step 6: fasten the plank so the ends stay down

The plank cannot simply rest on the cabinets if anyone is going to sit on an end overhang. An unsecured board can lift at the far side when weight or leverage is applied near the edge.

TRONES tops are thin moulded plastic, and screws driven upward through them can strip out under load. The reliable method is two L-brackets per cabinet. Screw each bracket into the underside of the plank and into the cabinet side walls where the plastic is thickest, near the front and back corners.

Use 16mm screws into the plank so they do not break through the seat surface. Check the screw length against the 38mm plank before driving. Across three cabinets, six brackets lock the board against lifting at either overhang.

Construction adhesive is another option. Run beads along each contact line between plank and cabinet top, then clamp the board overnight. Adhesive alone resists downward load well, although it gives less resistance to lifting at an overhang, so brackets remain the stronger answer for a seat people drop onto.

Step 7: check the load path

Run the numbers before anyone uses the bench. A 38mm pine plank spanning 51cm between cabinet supports, with a 100kg adult sitting centred, deflects only a couple of millimetres. That sits well inside what pine handles without taking a permanent bend.

The primary weak points are the back rail fixings and the bracket connection to the plastic cabinet. For the rail, a single timber stud and one 50mm screw rated for shear will hold far more than the few hundred newtons a seated person applies. Pull-out is the failure mode to plan around.

When someone sits on the front overhang, the cabinet tops want to tip forward and the rail screws take the pull. Two screws per rail into studs, together with the cabinet’s own click-fit engagement, spread that pull so one fixing does not carry the lever moment alone.

The bracket screws into the cabinet side walls are the genuine limit. Plastic threads strip at a fraction of the load timber screws hold, which is why the bracket belongs where the moulding is thickest and the shortest screw that still bites is the right screw. If you want the front overhang to take full seated weight at its tip, reduce that overhang to 30mm and let the cabinet front edge sit almost under the load point.

When this bench is the wrong fit

Skip this build if the hallway floor slopes more than about 15mm across the cabinet run. The click-fit rail system cannot easily absorb that amount of unevenness without visible gaps under the plank, while a fixed-leg bench levels out unevenness far more forgivingly.

The larger unresolved issue is depth. TRONES stores shoes on edge and tilted, which suits trainers and flats. Tall boots and wide work footwear are much harder to fold into the shallow cabinet.

That leaves a plain measurement problem in the shoe pile, especially if awkward footwear dominates the household.
