How Many Bath Bombs in a Gift Set? Counts, Box Sizes and Dividers

Common Gift Set Counts

Look across marketplace and pharmacy listings and bath bomb sets turn up in 4, 6, 7, 8, 10, 12 and 14 counts. Six and twelve are the most familiar, because they fall into tidy grids. Odd counts such as seven usually mean a mixed layout, often one larger bomb surrounded by smaller ones.

The count you choose fixes the grid, and the grid fixes the box. The table below gives typical planning footprints for set boxes built as custom bath bomb boxes product page, using a cell of about 70 mm for 2.5 in bombs and about 57 mm for 2 in bombs.

Count	Grid	Inner footprint, 2.5 in bombs	Inner footprint, 2 in bombs	Combined weight, 2.5 in at about 6 oz each
3	1 x 3 row	210 x 70 x 70 mm (8.3 x 2.75 x 2.75 in)	171 x 57 x 57 mm (6.7 x 2.25 x 2.25 in)	about 18 oz (1.1 lb)
4	2 x 2	140 x 140 x 70 mm (5.5 x 5.5 x 2.75 in)	114 x 114 x 57 mm (4.5 x 4.5 x 2.25 in)	about 24 oz (1.5 lb)
6	3 x 2	210 x 140 x 70 mm (8.3 x 5.5 x 2.75 in)	171 x 114 x 57 mm (6.7 x 4.5 x 2.25 in)	about 36 oz (2.25 lb)
8	4 x 2	280 x 140 x 70 mm (11 x 5.5 x 2.75 in)	228 x 114 x 57 mm (9 x 4.5 x 2.25 in)	about 48 oz (3 lb)
12	4 x 3, one layer	280 x 210 x 70 mm (11 x 8.3 x 2.75 in)	228 x 171 x 57 mm (9 x 6.7 x 2.25 in)	about 72 oz (4.5 lb)

All footprints are typical planning sizes. Divider walls add their own thickness to each row, and the final inner size is set from your measured bombs at quoting.

Weight Adds Up Faster Than Footprint

A single bomb is light. A set is not. Twelve 2.5 in bombs at about 6 oz each come to roughly 4.5 lb, close to 2 kg, and twelve 3 in bombs at about 8.9 oz each reach around 6.7 lb.

That total, not the look of the box, decides the board grade, the base construction and how the set travels. A six-count set handles well in a rigid or carton gift box; a twelve-count set that ships as a parcel usually wants corrugated around it or a corrugated mailer as the set box itself.

One Layer or Two

A twelve-count set laid flat needs a wide box, roughly the size of a sheet of paper. Stacking it as two layers of six halves the footprint: about 210 x 140 mm with a depth near 142 mm for 2.5 in bombs, allowing a board pad between layers.

Two layers save shelf space but hide the lower row when the lid comes off. A slim upright format is another route. One retail twelve-set of 5 cm bombs uses a box of 22.4 x 5.6 x 16.3 cm, which suggests the bombs stand one deep, four across and three high, facing the customer like a display panel.

Dividers and Inserts

Bombs that touch in transit can chip, and fragrance or colourant can pass between neighbours. Each cell needs a wall or a wrap.

Insert	How it holds the bombs	Where it fits
Slotted paperboard grid	Crossed strips form square cells	Even grids of 4, 6, 8 or 12
Die-cut cavity card	Round holes cradle each bomb from below	Shallow sets shown through a window or open lid
Moulded fibre tray	Formed pockets hold each bomb	Heavier sets and mixed sizes
E-flute cradle	Folded corrugated with cutouts	Sets that ship as parcels
Paper shred bed	Bombs nest loosely in fill	Wrapped bombs only, low counts

Grid dividers are folded and slotted together, not glued, so they ship flat beside the boxes. Cavity cards and cradles are die-cut to your bomb diameter, so measure the finished bombs first; the bath bomb box sizes blog covers how.

Box Styles for Multi-Bomb Sets

• Tray with lift-off lid: the classic set presentation; the whole grid shows at once.
• Drawer box: a tray that slides out of a printed sleeve, useful for four- and six-counts.
• Window lid: shows the colours without opening; pair it with wrapped bombs and a cavity card so nothing shifts behind the window.
• Corrugated mailer: the set box and the shipper in one, common for subscription and online orders.
• Upright display carton: one bomb deep, for a slim retail facing.

Board choices for each style are compared in the bath bomb box materials comparison blog.

Mixed Sizes and Odd Counts

A set built around one large bomb and several smaller ones needs its insert drawn around the largest piece first. The smaller cells then take the remaining space, often in a ring or along one side.

For a seven-count, a common layout places one centre bomb in a hexagon of six. That needs a moulded or die-cut insert, since a slotted grid only makes square cells. Ten and fourteen counts usually run as two rows of five or seven.

Mistakes to Avoid When Planning a Bath Bomb Set

1. No wall between bombs. Unwrapped bombs in contact can chip and swap colour.
2. Forgetting total weight. A box that feels fine with one bomb sags with twelve.
3. A box deeper than the bombs. Extra height lets the set shift; fill it or trim it.
4. An open window over unwrapped bombs. Dust and handling reach the product; use film over the window or wrap each bomb.
5. Grid dividers for odd counts. A seven-piece set will not sit neatly in square cells.

Next Step for Your Set Box

Send The Printing World the count, the bomb diameters, whether each bomb is wrapped, and how the set reaches the customer. If each bomb is wrapped in film or paper, tell us the wrap, since the cells are sized to the wrapped diameter and the wrap itself should suit the fragrance, colorant and product-contact needs of the bomb. Contact sales@theprintingworld.com or +16133831487, and see the gift boxes category page for related set formats.
