Kohler frameless medicine cabinet, 20 × 26 in review

A frameless anodized aluminum medicine cabinet with a mirrored interior and 108° hinges.

What the maker puts in writing

  • Mirrored surfaces inside and out, offering a clear view from every angle
  • “Two adjustable tempered-glass shelves, ready to hold everything from skincare essentials to daily toiletries”
  • “A full-overlay mirrored door finished with beveled edges”
  • “Two-way adjustable hinges that open a generous 108° for unobstructed access to every shelf”
  • “Install your way with hardware included for surface-mount or recessed setups, plus a side mirror kit for a polished surface-mount look”
  • Left-hand or right-hand door swing
  • “Anodized aluminum construction that resists rust and chips for enduring beauty in a busy bathroom”

Aluminum, which settles the main question on this shelf

Five of these seven cabinets are a wood product. A wood panel in a bathroom fails in one specific way: moisture reaches a cut edge, the material swells, and it does not go back. Above a sink the vulnerable edge is the underside, which is where the steam goes.

Anodized aluminum cannot do that.

Anodizing grows a hard oxide layer that is part of the metal rather than a coating on it, so it does not chip off the way paint does, and the aluminum underneath does not rust.

YTSMIR, the most expensive cabinet here at $229.99, publishes “high quality metal” without naming the metal or the treatment. This names both.

A hundred and eight degrees

That figure appears on one listing out of seven, and it is a specification written by somebody who has used a medicine cabinet.

A door that stops at 90° stands square across the cabinet front and blocks the shelf nearest the hinge. You can see the end of the shelf and not reach it — a third of the storage on a 20-inch cabinet.

A hundred and eight degrees swings the door clear.

And the hinges are two-way adjustable, which is how a door is brought back square after the cabinet settles on the wall. Six cabinets here describe their hinges. None of the others gives an angle.

The side mirror kit

A cabinet that can be recessed must have plain sides, because recessed they are inside the wall.

Surface-mount the same cabinet and those plain sides are at eye level on the wall beside you.

A side mirror kit covers them, so the thing reads as a mirrored block rather than a box screwed to a wall.

Three cabinets on this shelf offer recessed and surface mounting: this, the YTSMIR and the Tangkula. This is the only one that includes the kit.

A mirror inside as well

Mirrored surfaces inside and out.

Which sounds decorative and is practical: a mirrored back doubles the apparent depth and throws light into the shelves, so you can see what is at the back of a five-inch box without a flashlight.

Two tempered-glass shelves, which will not sag the way a wood shelf does and can be wiped rather than scrubbed. The load is not published — DICTAC, on this shelf, is the only listing that publishes one, at 22 lb (10 kg).

What it costs

Three point six square inches of mirrored front per dollar — against 10.1 from the fifty-dollar VASAGLE and 7.7 from the Tangkula.

Twenty by twenty-six inches is among the smaller fronts on this shelf at the second-highest price.

So this is not a purchase about mirror area. It is a purchase about the cabinet still being the same object in 2040.

And one number that is wrong

The catalog dimensions read 9.72 × 2.80 × 11.7 in (247 x 71 x 297 mm) — about 9.7 by 2.8 by 11.7 inches.

A 20 by 26 inch cabinet is not 9.7 inches wide. That is a data error, and the title figures are the ones to work from.

Strengths, and the catches

Strengths

  • Anodized aluminum: the only construction on this shelf besides YTSMIR’s metal that cannot swell when water reaches an edge
  • Hinges opening a published 108°, which is what clears the end shelf — no other listing here gives an angle
  • A side mirror kit in the box, so a recessed-capable cabinet surface-mounts without plain box sides showing

Compromises

  • Three point six square inches of mirrored front per dollar, against 10.1 from the cheapest cabinet here
  • Twenty by twenty-six inches is among the smaller fronts on this shelf at the second-highest price
  • No shelf load published, and the catalog dimensions are wrong

The questions we get

Why is anodized aluminum worth paying for in a bathroom?

Because it cannot do the thing that kills wood cabinets. Five of the seven cabinets on this shelf are particleboard, MDF or "engineered wood", and a wood panel swells permanently once moisture reaches a cut edge — which above a sink is the underside. Anodizing is an electrochemical treatment that grows a hard oxide layer integral to the aluminum, so it does not chip off the way paint does and the metal beneath does not rust. Kohler states it resists rust and chips. YTSMIR, the most expensive cabinet here, publishes metal construction without naming the metal or the treatment.

A hundred and eight degrees — why does that matter?

Because a door that stops at 90° stands square across the front of the cabinet and blocks the shelf nearest the hinge. You can see into the cabinet and not reach the end of it, which on a 20-inch cabinet is a third of the storage. Opening past square — 108° here — swings the door clear. It is the kind of specification that only appears when somebody has used the product, and it is the only hinge angle published on this shelf. The hinges are also two-way adjustable, which is how a door is made to sit square after the cabinet settles.

What is the side mirror kit for?

For the sides of the box. A cabinet that can be recessed has to have plain, unfinished sides, because recessed they are inside the wall and invisible. Surface-mount the same cabinet and those sides are on show at eye level, on the wall beside the mirror. A side mirror kit covers them so the cabinet reads as a mirrored block rather than a box screwed to the wall. Three cabinets on this shelf offer both mounting methods — this, the YTSMIR and the Tangkula — and this is the only one that includes the kit.
