Niche, Bench and Shelf Heights That Actually Work

A bathroom has three fixed storage and surface elements built into the wall or joinery before anyone moves in: the shower niche, the vanity bench and any open shelving. Get the heights wrong and there is no easy fix afterward, since the niche is tiled into the frame, the vanity is plumbed and fixed, and the shelf is set into a cavity. Every one of these has to be on the drawings before the frame goes up, not worked out on site.

Shower niche: height, depth and where it sits in the wall

The comfortable range for a shower niche is 900 to 1,200 mm from the finished floor to the bottom of the opening, with most bathrooms landing around 1,000 to 1,100 mm so the niche sits at chest to eye level with nothing to reach or bend for. A niche over a bath, rather than in a standing shower, usually sits lower, closer to the lip of the bath.

Standard niche sizes run 355 to 625 mm wide and 260 to 365 mm tall, with 600 x 300 mm a common size that lines up cleanly with most wall tile modules. Depth is set by the wall, not preference: a standard 90 mm timber stud wall gives a niche around 80 to 100 mm deep once tiled, and it has to land between two studs rather than cut through one. Standard residential stud spacing is 450 or 600 mm centres, so niche width and position need to be checked against the framing layout before the frame is built.

AS 3740:2021 treats a niche as part of the waterproofed wall, not a separate detail. The lining (back, sides, top and base) needs the same water-resistant substrate as the rest of the shower, and the base needs its own fall, a minimum of 1:100, back toward the shower rather than pooling. A niche left off the waterproofing documentation is a corner the waterproofer has to work out on the day, which is exactly the kind of on-site decision that causes rework.

Vanity bench: the height that suits most people

The industry-standard vanity bench height in Australia is 860 mm from finished floor to the top of the benchtop, and most floor-mounted vanities are built to 850 to 900 mm. It has become the default for new builds because it suits the average adult without bending, the same way a kitchen bench height is standardised.

Wall-hung vanities are more flexible, commonly hung anywhere from 800 to 900 mm to suit the household. Where a bathroom needs to meet AS 1428.1 accessible design, benchtop height comes down to roughly 720 to 840 mm, with basin rim height typically specified at 800 to 830 mm.

One detail that catches people out: if the basin sits on top of the bench rather than set into it, the basin's own height comes off the vanity height, not on top of it. A 100 mm tall above-counter basin on an 860 mm vanity gives a rim over 950 mm, too high for most users. The documentation needs to show cabinet height and basin type together, not one number alone.

Shelf and seat heights inside the shower

Open shelving and a shower seat or bench follow the same logic as the niche: useful only if the height matches what goes on it. A shower seat or fold-down bench sits at 450 to 490 mm for comfortable seated use, tightening to 470 to 480 mm where the bathroom needs to meet AS 1428 accessible requirements. A low storage ledge, built for holding items rather than sitting, generally sits lower again, around 400 mm.

For open linen or towel shelving outside the shower, keep anything used daily below about 1,200 mm, and reserve anything above 1,700 mm for stock grabbed occasionally. A shelf depth of around 300 mm suits general storage, closer to 450 mm if it holds folded towels or linen rather than bottles and jars.

Why this belongs on the drawings, not the site

None of these numbers are hard to find individually, but a bathroom carries all three in one small room, each interacting with the framing, waterproofing and tile setout. A niche height decided after the frame is up means moving studs or moving the niche. A vanity height decided after the plumbing is roughed in means a basin that sits wrong. Locking the heights into the drawing before framing keeps every trade working from the same numbers instead of guessing on the day.

Every F&F documentation package sets out niche, bench and shelf heights on the internal elevations alongside the floor plan, reflected ceiling plan and FF&E schedule, so the framer, waterproofer and tiler all work from the same drawing rather than a verbal instruction on site.
