7 Ways to Upgrade Your Bathroom with 3D Printing on a Budget

A well-designed bathroom balances aesthetics with practicality, creating a space that feels both relaxing and functional. If you own a 3D printer, you already have a powerful tool to customize your bathroom without spending a fortune. From organizational solutions to decorative accents, here are seven affordable ways to transform your bathroom using 3D printing technology.

1. Choose the Right Filament for Moisture Resistance

Before diving into specific projects, understand that bathrooms present unique challenges for 3D-printed items. The combination of humidity and moisture can degrade certain materials over time. PLA, the most common filament choice, is affordable and beginner-friendly but struggles in wet environments and breaks down under UV exposure. For bathroom projects, PETG is a far better option. It costs roughly the same as PLA yet handles moisture much more effectively and resists something called “PLA creep,” which causes objects to sag under weight. If you want maximum durability, ABS and ASA are engineering-grade alternatives, though they’re pricier and require better ventilation during printing.

2. Add Practical Hooks and Towel Hangers

Hooks might seem like a straightforward project, but they’re incredibly useful when placed strategically in your bathroom. An over-glass shower hook lets you hang towels and robes directly on your shower screen or door without needing wall space. You can also print radiator hooks to maximize your existing fixtures, provided your radiator doesn’t generate excessive heat. For added convenience, explore parametric designs that adjust to fit various radiator styles. Pressure-locked towel hangers offer another solution and can be secured with screws, double-sided tape, or heavy-duty adhesive strips. Always print hooks with PETG to minimize the risk of them sagging under the weight of wet towels.

3. Organize Toothbrushes and Personal Care Items

Messy toothbrushes clutter bathroom countertops and consume valuable real estate in small bathrooms. Wall-mounted toothbrush holders are some of the simplest 3D prints and free up counter space instantly. You’ll find designs for individual holders with covers, automatic-closing designs, multi-person holders for families, and specialized racks for electric toothbrushes. Beyond toothbrushes, print organizers for razors, hairbrushes, combs, tweezers, and even toothpaste. Want something fun? Several makers offer LEGO-themed toothbrush holders that appeal to kids and collectors alike. These organizational prints cost pennies in materials and hours in print time.

4. Maximize Storage with Modular Organizers

3D printing has become synonymous with organization, especially through projects like Gridfinity, which applies equally well to bathrooms. Self-draining organizers, parametric drawer units, wall-mounted caddies, and modular makeup trays come in dozens of designs. You can print matching sets in a single color scheme to create a cohesive look, or add visual interest with layer-based color changes as your filament switches mid-print. These organizers hold soap, face cloths, cosmetics, and toiletries while maximizing every inch of available space.

5. Install Shower Organizers That Handle Moisture

Shower organizers live in the wettest part of your bathroom, making material selection critical. This is where PETG truly shines, as shower caddies need frequent replacement anyway due to mildew and grime buildup. Corner shelves attach to standard shower poles using simple clamps, while others hang from glass partitions. For the minimalist aesthetic, self-draining soap dishes require almost no installation and prevent water pooling. Some designs use heavy-duty double-sided tape that bonds effectively in moist conditions and holds firm once cured. Stackable modular corner shelves work perfectly in shower-over-tub configurations, letting you add more storage as needed.

6. Embrace Japandi Design Aesthetics

“Japandi” combines Japanese and Scandinavian design principles, and this style has exploded in the 3D printing community for good reason. The ribbed surfaces characteristic of Japandi items expertly hide the layer lines that reveal an object’s 3D-printed origin, making your creations look like premium home goods instead. You can find Japandi-style complete bathroom sets, toothbrush holders, Q-tip dispensers, toothpaste squeezers, and toilet paper holders. This design approach lets you commit to one elegant visual theme throughout your bathroom while still enjoying the cost savings of 3D printing.

7. Mount Grooming Device Holders

The 3D printing community constantly develops custom mounts for popular electronics. If you use a Dyson hairdryer, Philips OneBlade, or Oral-B electric toothbrush, someone has likely already designed a holder for it. Wall mounts for hairdryers, clamping stands for shavers, and brackets for hair straighteners are readily available designs. Since your printer can produce replacement holders when old ones wear out, you’ll never pay premium prices for branded organizers again. Keeping your grooming devices charged and organized becomes effortless with custom printed solutions tailored to your specific equipment.

Getting Started

Begin with simple projects like toothbrush holders or hooks to build confidence, then progress to more complex organizers as you develop your printing skills. The beauty of 3D printing for bathroom upgrades is that material costs remain minimal while customization options are virtually unlimited. Choose PETG for any items exposed to moisture, commit to a design aesthetic you love, and enjoy a bathroom that reflects your personal style without demanding thousands of dollars in renovation costs.
