Find bathroom parts at BlueStars Parts for common ventilation, shower, tub, and drain repairs. Shop bathroom exhaust fan motors, grille covers, shower valve cartridges, drain stoppers, strainers, mounting hardware, and other replacement components by model or part number.
If your bathroom fan will not start, airflow is weak, your shower is leaking, or a tub drain no longer seals properly, replacing the worn component may restore normal operation without replacing the entire fixture.
Which Bathroom Part Matches Your Problem?
- Bathroom exhaust fan will not start: inspect the fan motor assembly, wiring connection, and power supply.
- Bathroom fan runs but airflow is weak: check the motor, blower wheel, grille, housing, and duct for dust buildup or mechanical wear.
- Bathroom fan is noisy or rattling: worn motor bearings, a damaged blower wheel, or a loose grille may be the cause.
- Bathroom fan grille is cracked or missing: replace the grille or cover with the correct size and spring configuration.
- Shower drips when turned off: a worn shower valve cartridge may no longer seal correctly.
- Shower temperature is difficult to control: inspect the pressure-balance cartridge and valve components.
- Bathtub will not hold water: check the drain stopper, trim assembly, and drain fit.
- Shower or tub drain is missing a cover: replace the drain strainer or cover using the correct diameter and mounting style.
Before ordering, compare the original part number, model number, dimensions, and mounting or connection type.

How to Find the Right Bathroom Replacement Part
The most reliable way to find the correct bathroom replacement part depends on the fixture you are repairing.
- Step 1: Identify the fixture. Determine whether you are repairing an exhaust fan, shower valve, bathtub drain, drain cover, or another bathroom component.
- Step 2: Find the model number. For bathroom exhaust fans, check the label inside the fan housing after removing the grille. For faucets or shower valves, identify the faucet or valve series where possible.
- Step 3: Find the original part number. Fan motors, cartridges, grille covers, and other replacement components often have a printed, molded, or stamped part number.
- Step 4: Measure key dimensions. Compare grille size, housing size, drain diameter, cartridge dimensions, mounting spacing, or thread diameter as applicable.
- Step 5: Check cross-reference numbers. Some replacement components list multiple manufacturer or superseded part numbers.
- Step 6: Confirm compatibility. Review the compatible models, specifications, connectors, mounting style, and included components before ordering.
Quick Tip: Do not choose bathroom repair parts by appearance alone. Fan motors, shower cartridges, drain stoppers, and grille covers can look similar while using different dimensions, mounting points, or internal designs.
Bathroom Exhaust Fan Parts: What Should You Check?
Bathroom ventilation is one of the main repair categories represented in this collection. If your fan is not working properly, inspect:
- Motor assembly: replace it when the motor fails to start, overheats, runs intermittently, or makes grinding noises.
- Blower wheel: check for cracks, dust buildup, or restricted rotation.
- Fan grille or cover: replace damaged, loose, or missing covers using the correct dimensions and spring arrangement.
- Housing and duct: clean dust and debris before assuming the motor itself has failed.
- Power connection: turn off power at the circuit breaker before servicing electrical bathroom fan components.
How to Choose Shower and Bathtub Parts
Shower Valve Cartridges
A shower cartridge may need replacement when:
- Water continues dripping after the handle is turned off
- The handle becomes stiff or difficult to operate
- Hot and cold water are difficult to balance
- The valve no longer shuts water off completely
Bathtub Drain and Stopper Parts
Before buying a bathtub drain stopper or trim kit, compare:
- Drain opening diameter
- Thread type
- Existing stopper style
- Overflow plate configuration
- Finish, when relevant
- Included hardware
Universal does not mean every bathtub. The listed measurements still need to match your existing drain.
Can Bathroom Replacement Parts Fit Multiple Brands?
Yes. Some bathroom replacement parts fit multiple models or product families, but compatibility depends on the specific component.
Bathroom exhaust fan motors and grille covers may fit several Broan or NuTone models when the housing dimensions and part numbers match. Shower cartridges are usually tied more closely to a specific valve family or series. Universal drain parts rely primarily on dimensions, thread type, and drain design.
Before ordering, compare:
- Brand and model
- Original part number
- Replacement or cross-reference numbers
- Dimensions
- Mounting configuration
- Thread type where applicable
- Electrical specifications for fan motors
- Compatible model list

Bathroom Parts FAQs
How do I know which bathroom exhaust fan motor I need?
Find the model number inside the fan housing and compare it with the replacement motor's compatibility list. Also verify the original motor part number, housing size, airflow rating, mounting configuration, and electrical specifications.
Why is my bathroom exhaust fan running but not removing moisture?
Dust buildup, a clogged duct, a weak motor, a damaged blower wheel, or restricted airflow can reduce ventilation. Clean the housing and duct first, then inspect the motor and blower assembly if airflow remains weak.
How do I know which shower cartridge fits my faucet?
Identify the faucet or valve brand and series, then match the original cartridge number and compatible valve models. Similar-looking cartridges are not necessarily interchangeable.
Can I replace a bathtub drain stopper myself?
Many external drain stoppers and strainers are suitable for DIY replacement when the drain size, thread type, and stopper design are correctly matched. If the repair requires accessing or replacing plumbing below the tub, professional service may be more appropriate.
When should I replace a bathroom fan grille?
Replace the grille if it is cracked, badly discolored, missing springs, no longer stays attached, or blocks airflow because of damage that cannot be cleaned or repaired.
