# What filament is best for bathroom/shower parts?

The shower thread's reports are PLA parts the posters say are still in use, including a soap dish from about 2016 and a PLA tub screen for about a year and a half. That is not a waterproof rating. PETG and ASA list higher heat resistance in the catalog.

The shower thread's reports are PLA parts the posters say are still in use, including a soap dish from about 2016 and a PLA tub screen for about a year and a half. That is not a waterproof rating. PETG and ASA list higher heat resistance in the catalog.

The only shower question in this bank is a PLA soap dish. The replies that report a result say the PLA parts are still in service. PETG and ASA are here as catalog alternatives with higher listed temperatures.

## What the shower replies report

[r/BambuLab 1bb49vl](https://www.reddit.com/r/BambuLab/comments/1bb49vl/) asks how PLA will hold up as a soap dish. A score-60 reply has a PLA hair screen in a tub for about a year and a half. A score-31 reply still uses a soap dish printed around 2016. A score-20 reply has Polyterra white trays and says to clean them, because mold or soap residue is the likelier failure. A score-10 reply says Polyterra PLA has survived more than a year of very hot showers without melting. Polyterra is not a catalog id. [PLA Basic](/brand/bambu-lab/pla-basic) lists 190–230 °C (374–446 °F) and a bed of 35–45 °C (95–113 °F). That row is a PLA sheet, not the soap-dish spool.

Watertight printing is [waterproof filament](/answers/waterproof). Sun and heat outdoors are [outdoor filament](/answers/outdoor). PETG process is [good PETG prints](/answers/petg_print).

## PETG and ASA temperatures

[PolyLite PETG](/brand/polymaker/polylite-petg) lists 220–250 °C (428–482 °F) and a bed of 70–90 °C (158–194 °F), with drying at 65 °C (149 °F) for 6 h. [SUNLU PETG](/brand/sunlu/petg) lists 240–260 °C (464–500 °F) and a bed of 60–70 °C (140–158 °F), with drying at 60–65 °C (140–149 °F) for 6–8 h. [Bambu ASA](/brand/bambu-lab/asa) lists 235–260 °C (455–500 °F) and a bed of 90–110 °C (194–230 °F), with drying at 80 °C (176 °F) for 8 h. None of those sheets states a shower life. [PETG](/material/petg), [ASA](/material/asa), and [PLA](/material/pla) are the material pages.

## The other four threads

[r/FixMyPrint ugv0ur](https://www.reddit.com/r/FixMyPrint/comments/ugv0ur/) is how to store opened spools. Replies name zip bags, cereal containers, and tubs of desiccant.

[r/FixMyPrint una950](https://www.reddit.com/r/FixMyPrint/comments/una950/) asks if a repeating gap is humid filament. The score-33 reply says the extruder gear is wobbling. The top comment is a joke about the model's shape.

[r/BambuLab 1vcujin](https://www.reddit.com/r/BambuLab/comments/1vcujin/) is a SUNLU AMS heater. The poster's hygrometer went from 10% to 31% relative humidity, and Bambu Studio showed D. Replies say the drying vent was closed, so the moisture stayed in the box. Those percentages are that meter.

[r/FixMyPrint xbs0hy](https://www.reddit.com/r/FixMyPrint/comments/xbs0hy/) asks if a print that fails after 6 hours in a dryer is humidity. The score-42 reply says heat creep. The poster later took the printer out of a tent and says it recovered. [Polymaker](/brand/polymaker) and [SUNLU](/brand/sunlu) are the brand indexes.

## What the community says

r/BambuLab 1bb49vl asks how PLA will hold up as a soap dish in a child's shower. A score-60 reply has a PLA hair screen in a tub drain for about a year and a half and says it is fine. A score-31 reply has used a soap dish printed around 2016 and says it is still in the bathroom. A score-20 reply has Polyterra white trays, says they have not melted, and says to clean them because mold or soap residue is the likelier problem. A score-10 reply printed the same dish in Polyterra PLA and says more than a year of very hot showers has not melted it. r/FixMyPrint ugv0ur asks for cheap storage for opened spools. Replies name zip bags, a filament dryer, cereal containers, and airtight tubs with desiccant. r/FixMyPrint una950 asks if a repeating under-extrusion pattern is humid filament. The top comment is a joke about the shape. The score-33 reply says the extruder gear is off center or wobbling. r/BambuLab 1vcujin installed a SUNLU AMS heater and watched a hygrometer rise from 10% to 31% relative humidity, graded D in Bambu Studio. Replies say to open the vent so wet air can leave. r/FixMyPrint xbs0hy asks if a print that goes bad after 6 hours in a dryer is humidity. The score-42 reply says it is heat creep. The poster later moved the printer out of a tent and says the print recovered.
