Bath Caddy Buying Guide: What to Look For and Which Size Fits Your Tub

Most Australian freestanding and back-to-wall baths measure between 1400mm and 1700mm in overall length, with widths generally sitting between 700mm and 800mm. A caddy sits across the width of the tub rather than the length, so the width measurement, not the overall length, is what determines whether it fits. An adjustable caddy needs an expansion range that comfortably covers your tub's outer width plus a small overlap on each side so it sits securely rather than balancing on the edge.

• Compact freestanding baths, such as the Clark Round Freestanding Bath 1400mm, sit toward the narrower end of the standard width range.
• Larger two-person freestanding baths, such as the Caroma Cupid Freestanding Bath 1700mm, run wider, so check the top end of an adjustable caddy's range before buying.
• Measure outer rim to outer rim, not the inner basin width, since that's the surface the caddy actually rests on.
• • A caddy that's too short for the width won't sit flat and risks tipping when weight lands on one end.

Bath caddy materials fall into a handful of categories, and how well they hold up in constant moisture matters more than how they look on day one. Bamboo is the most common budget option but is porous by nature, so it can swell, stain or grow mould over time without regular sealing. Solid surface and stainless steel resist water damage far better and hold their finish for longer, which is part of why they cost more upfront.

• Bamboo and other untreated timber caddies are light and affordable but need periodic oiling or sealing to resist water absorption.
• Teak holds up better than bamboo thanks to its natural oil content, though it still benefits from occasional maintenance.
• Stainless steel resists corrosion and mould completely but can feel cold underhand and shows water spots more visibly.
• Solid surface, like the Turner Hastings Solid Surface Bath Caddy, resists scratches, stains and moisture without warping, and never needs oiling or sealing.

Designer tip: a matte finish hides water spots and soap residue far better than a glossy one, which matters on a surface that's wiped down daily.

An adjustable, telescoping caddy is the safer pick if you don't know your bath's exact width or plan to move it to a different tub later. A fixed-width caddy works just as well, and often sits more securely, when it's built to match a specific bath range rather than treated as a compromise. TBS's own Turner Hastings Solid Surface Bath Caddy is a good example: it's cut to a fixed 940mm length and 200mm width to suit the Turner Hastings TitanCast and MagnaCast bath ranges specifically, so the fit is exact rather than approximate.

• Expandable telescoping-arm caddies suit older baths or ones where the exact rim width isn't documented anywhere.
• A fixed-width caddy matched to a specific bath range sits flush without the gaps or overhang an adjustable arm can leave behind.
• Fixed designs are generally sturdier, since there's no adjustable joint to loosen or wobble with repeated use.
• If your tub is a non-standard shape, such as a corner or slipper bath, an adjustable caddy has a better chance of fitting properly.

The features worth paying extra for are the ones you'll actually use every time you bathe, not the ones that photograph well. A stable shelf area wide enough for a book, tablet or phone earns its keep day to day, while niche add-ons like a built-in soap dispenser add convenience but also add more surfaces to keep clean.

• Non-slip feet or rubber grips stop the caddy sliding on wet enamel or acrylic, which matters more on a gloss finish than a matte one.
• A stable, flat spot for a book, tablet or phone gets used more often than a dedicated wine glass slot for most households.
• A removable or sliding tray section makes cleaning around the caddy easier without lifting the whole unit off the bath.
• Built-in soap or sponge holders are handy but add extra corners that trap moisture, so weigh the convenience against the upkeep.

Yes, in most cases, because the two bath types differ in how much of the rim is actually accessible. A freestanding bath, like the ADP Placido or the Caroma Urbane Back To Wall Freestanding Bath, has both long rims fully exposed, so a caddy can be positioned anywhere along its length. A built-in or alcove bath sits in a recess with tiled walls on three sides, which limits caddy placement to the front rim only.

• Freestanding and back-to-wall baths, such as the Caroma Urbane Back To Wall Freestanding Bath 1675mm, expose the full rim, so a caddy can sit wherever suits reach.
• A built-in or alcove bath limits a caddy to the front edge only, since the other three sides are boxed in by tiled walls.
• Wall-mounted storage, such as the Clark Square Wall Caddy, is a practical alternative for a built-in bath where a rim-mounted caddy would sit awkwardly close to the tiles.
• A shower screen hook, like the Clark Square Shower Screen Hook, gives a freestanding bath with an attached screen an extra spot for a towel or robe, without taking up caddy space on the rim.
