A bathroom must be elegant and relaxing—but it also has to function. That's where 3D printing comes in. With the right filament choices and design selections, you can create bathroom accessories that look polished, last in humid conditions, and cost a fraction of their retail equivalents.
Key Considerations
| Factor | PLA | PETG | ABS/ASA |
|---|---|---|---|
| Moisture resistance | Poor | Good | Good |
| UV resistance | Poor | Moderate | Good |
| Print difficulty | Easy | Moderate | Advanced |
| Price | Low | Moderate | Higher |
| Toxic gases | Minimal | Minimal | Yes, requires ventilation |
Material Matters
PLA is the most common 3D printing filament—cheap, non-toxic, and easy to use. For bathrooms, though, it's a poor choice. PLA degrades in moisture and UV light, meaning humid conditions will cause your prints to deteriorate over time.
PETG solves this problem. Comparable in price to PLA and only slightly more challenging to print, it holds up well in damp environments. If you want longer-lasting results, PETG should be your default for anything touching bathroom moisture.
ABS and ASA offer superior durability and UV resistance, but they cost more and emit toxic gases during printing. Only consider them if your printer has proper ventilation.
What to Print
Hooks and Hangers
Hooks might seem boring, but they're incredibly useful. A critical issue with PLA under sustained load is "creep"—the material slowly deforms over time. PETG resists this effect much better. Print shower hooks that hang over glass doors, pressure-locked towel hangers for wall mounting, or parametric radiator hooks that fit any design.
Toothbrush Organization
Bathroom storage is limited, and toothbrushes create visual clutter. Solutions abound: wall-mountable individual holders with covers, auto-opening SnapBrush designs, three-in-one family holders, and specialized models for Oral B electric brushes or toothpaste. Some designs even hold razors, hairbrushes, or tweezers.
Drawer and Counter Organizers
3D printing's association with organization owes much to projects like Gridfinity. For bathrooms, look for self-draining counter organizers, parametric drawer dividers, wall-mounted caddies, and modular toiletry organizers. Match colors by using the same filament throughout, or create visual interest with layer-based color changes.
Shower Storage
Shower organizers get wet constantly—another reason to avoid PLA here. Options include glass-mount hanging designs, pole-attached shelves for adjustable shower heads, corner shelves using strong double-sided tape, and minimalist self-draining soap dishes.
The Japandi Shortcut
"Japandi"—a fusion of Japanese and Scandinavian aesthetics—has become ubiquitous in 3D printing for good reason. The ribbed texture common to these designs naturally hides layer lines, disguising the fact that items came from a printer rather than a premium homewares brand. Whole bathroom accessory sets exist in this style: toothbrush holders, Q-tip dispensers, toothpaste squeezers, and toilet roll holders. If you want an elegant unified look, Japandi delivers it effortlessly.
Who Should Print?
- Renters** benefit most—many organizers attach with adhesive strips or double-sided tape rather than screws
- Budget-conscious organizers** can print modular systems for a fraction of retail organizer costs
- Design-conscious makers** can match colors and styles across all bathroom accessories
- Pet owners** might appreciate the LEGO-themed toothbrush holder for kids
Key takeaways
- Always use PETG or higher-grade filaments for bathroom prints—PLA degrades in moisture
- Hooks printed in PLA suffer from creep under sustained weight; PETG avoids this
- Japandi designs elegantly disguise 3D-printed layer lines
- Modular systems like Gridfinity-inspired organizers offer customizable storage
- Most bathroom prints can mount without screws, making them rental-friendly
Frequently asked questions
Can I use PLA filament for bathroom prints?
PLA degrades in humid conditions and under UV light. For anything in a bathroom, use PETG or higher-grade filaments for durability.
What holds 3D printed organizers to walls without screws?
Strong double-sided tape (often called "3M strips" or "black magic tape") bonds firmly in moist environments after adequate curing time. Many designs specifically accommodate rental-friendly mounting.
How do I make my 3D prints look more polished?
Japandi-style designs naturally hide layer lines through their ribbed texture. Alternatively, use a single-color filament throughout your bathroom accessories for a cohesive look.
What bathroom items are most worth 3D printing?
Toothbrush holders, shower organizers, drawer dividers, and hooks offer the best combination of frequent need, customization options, and printability.
Can I print soap dishes that drain properly?
Yes. Look for self-draining designs with built-in slope or drainage holes to prevent water pooling.
