3D Printed Bathroom Organisers: Toothbrush Holders to Shower Shelves

Bathrooms are small, wet and full of things that need a home: toothbrushes, razors, bottles, hairdryers, the kid's bath toys. Store-bought organisers rarely match the tile, the corner or the gap next to the sink. 3D printing lets you make one that does. Here is what we print for bathrooms, what it should be printed from, and how it holds up to water and steam.

Popular ideas

• Toothbrush holders with a slot per brush, a drip tray and a spot for the electric brush charger.
• Razor hooks and blade holders for the shower wall, with a drainage slope.
• Shower caddies and corner shelves cut to the angle of your corner, with drain holes so nothing sits in water.
• Soap dishes with raised ribs that keep the bar dry.
• Hairdryer and straightener holsters that mount inside a cabinet door.
• Drawer trays for makeup, cotton pads and hair ties, sized to the drawer.
• Toilet paper holders and spare-roll stands in a shape that matches the rest.
• Bath toy drying baskets and toothpaste tube squeezers.
• Cable clips and holders for an electric toothbrush or shaver cord.

Many of these are the bathroom versions of what we describe in 3D printed desk organisers: objects designed around your things instead of an average.

Water, steam and plastics

This is the important part. The standard printing plastic, PLA, is fine on a dry shelf but not ideal in a shower: its glass transition is only around 55-60 °C, so hot water can warp it, and long exposure to warm humidity slowly degrades it and makes it more brittle. For anything that gets wet, we recommend PETG or ASA.

Location	Material	Notes
Dry shelf, cabinet interior	PLA or PETG	Any colour, any finish
Sink area, toothbrush holder	PETG	Water resistant, easy to wipe
Inside the shower	PETG or ASA	Higher heat resistance (glass transition around 80 °C for PETG, about 100 °C for ASA)
Items that must flex (squeegee, suction parts)	TPU	Flexible and waterproof

A printed part is made of many fused layers, and a lot of thin walls can wick water through tiny gaps. For trays and caddies we print thicker walls and more perimeters, and we can seal the surface. The same principle applies to vases, as covered in can 3D printed vases hold water?.

Mounting without drilling tiles

Nobody wants to drill a tile. Most of our bathroom items are designed for one of these:

• Adhesive pads rated for wet areas (water-resistant Command strips or VHB tape) on a flat printed back.
• Suction cup mounts, where the printed part has a socket for a standard suction cup.
• Over-door or over-glass hooks for shower screens and cabinet doors.
• Tension rod clips for a shower rod.
• Screw mounting where drilling is fine, with countersunk holes.

Tell Fantasy Lab 3D which one you prefer and we will build it into the design.

Colours and looks

Bathroom prints do not have to be white plastic. Matte white, black and grey blend with most tiles; marble filament looks like stone and hides water spots; pastel tones suit a kids' bathroom. A smooth, sanded finish is easier to keep clean than raw layer lines, so for anything that touches soap scum we recommend a finished surface. Names or icons on each toothbrush slot are a small touch families like.

Hygiene and cleaning

Printed organisers are cleaned like any plastic: warm water, mild detergent, an old toothbrush for the corners. Avoid boiling water, dishwashers and bleach on PLA. PETG tolerates hotter water. Drainage design matters as much as material: a good tray has a slope or holes so water leaves. More care tips in caring for 3D printed items.

How ordering works

Send a photo of the corner, wall or drawer with rough measurements, or a link to a design you like. Simple hooks and dishes usually print in a few hours; a corner shelf or a multi-slot holder can take a day or more. The price depends on size, material and finish, so request a quote.
