Can toe fungus spread in shower?

Toe fungus, also known as athlete’s foot or tinea pedis, is a common fungal infection that can affect the feet. It typically causes itching, burning, cracking, and scaling on the feet. One of the most common ways that people wonder if toe fungus can spread is in public showers and locker rooms.

Can You Catch Toe Fungus in Public Showers?

Yes, it is possible to catch toe fungus in public showers and locker rooms. The warm, moist environment of public showers provides ideal conditions for fungal growth and transmission. When someone with athlete’s foot uses a public shower, they can shed fungal spores onto the floor. If you walk barefoot in the same area, the spores can stick to your feet and cause an infection.

Fungal spores are very resilient and can survive for long periods on surfaces like shower floors and locker room benches. Even cleaning with normal detergents may not kill all the spores. So you could pick up an infection from surfaces in public showers even if no one with active athlete’s foot was recently there.

Ways Toe Fungus Spreads in Showers

  • Direct contact with infected feet
  • Contact with contaminated surfaces – floors, benches, etc
  • Airborne spores from infected feet
  • Sharing towels, shoes, or other items
  • Moist environment favors fungal growth

Tips to Prevent Spread of Toe Fungus in Showers

If you are using public showers, there are some precautions you can take to lower your risk of catching or spreading athlete’s foot:

  • Wear shower shoes or flip flops
  • Don’t share towels, shoes, socks, etc with others
  • Wash feet thoroughly with soap after showering
  • Dry feet completely after shower, especially between toes
  • Apply antifungal powder to feet after showering
  • Disinfect shower floors/benches with antifungal cleaners

These tips help minimize contact between your bare feet and contaminated surfaces where fungal spores may be present. They also help remove any spores that may get on your skin so they have less chance to cause an infection.

Can Toe Fungus Spread at Home?

Yes, it’s also possible for toe fungus to spread to other family members at home if precautions are not taken. Here are some ways it can happen:

  • Sharing towels, shoes, socks, etc. with an infected person
  • Walking barefoot in areas an infected person walked barefoot
  • Not disinfecting shower/bath areas between uses
  • Failure to treat infections promptly
  • Family members with weak immune systems

To prevent transmission at home, family members should not share any personal items like towels and socks. Surfaces like shower floors and bathtubs should be cleaned and disinfected regularly. Infected family members should see a doctor for antifungal treatment. Treating the infection quickly can help stop fungi from spreading.

Who is Most at Risk for Spreading Toe Fungus?

Individuals most likely to spread toe fungus include:

  • People with current athlete’s foot infections
  • Those not treating current infections
  • People with toenail fungus
  • Those with weak immune systems
  • Elderly individuals
  • People who frequently use public showers
  • Individuals who share personal items like shoes and socks

People exhibiting symptoms of athlete’s foot like itching, burning, and cracked skin have high concentrations of fungal spores on their feet. If precautions are not taken, they can easily transmit the infection to others through direct contact or by shedding spores into the environment.

Individuals with toenail fungus also have high fungal loads and can spread infection. Other high risk groups include the elderly, those with weakened immune systems, and people who use public facilities like gyms and pools frequently.

How to Know if Toe Fungus is Spreading

Signs that a toe fungus infection may be spreading include:

  • Itchy, red, cracked skin between the toes or on soles of feet
  • Burning, stinging sensation on feet
  • Flaking, scaly skin on feet
  • Discolored, thickened toenails
  • Watery discharge or foul odor from feet
  • Spreading rash on feet and ankles

These symptoms indicate active fungal growth. If they occur in multiple family members or people who share showers/locker rooms, it suggests the infection has been transmitted. The infection often starts between the toes but can spread across the soles and sides of feet if left untreated.

Seeking Treatment

If athlete’s foot symptoms develop, you should seek treatment promptly from your doctor to get on top of the infection before it can spread further. Antifungal creams, sprays, and oral medications can help eliminate toe fungus.

Be sure to follow all treatment directions carefully. Even if symptoms improve, finishing the full course of medication is important to kill the fungus completely and prevent recurrence.

How to Stop the Spread of Toe Fungus in the Home

To control a toe fungus outbreak in a family setting, the following tips can help stop transmission between household members:

  • Have infected family members see a doctor for oral antifungal medication
  • Disinfect bathrooms and showers regularly with antibacterial cleaners
  • Do not share towels, clothing, or other personal items
  • Wash sheets, pajamas, socks in hot water to kill fungi
  • Have infected family members wear flip flops around the house
  • Treat all family members prophylactically with antifungals

Follow these steps until all family members have been symptom-free for 2 weeks. Be sure to disinfect all shared areas thoroughly to eliminate infectious fungal spores.

Preventing Recurrence

To avoid repeat outbreaks of athlete’s foot in a family or shared living setting:

  • Inspect family members’ feet regularly
  • Treat any signs of infection promptly
  • Disinfect showers/bathrooms weekly
  • Do not share towels, shoes, clothes
  • Wash bedding/linens in hot water weekly
  • Keep feet clean and dry

Staying vigilant about foot hygiene and disinfecting will help prevent fungal spores from taking hold again. Treating any recurrence aggressively before it spreads is also key.

When to See a Doctor

You should see a doctor if:

  • Athlete’s foot does not improve with OTC antifungals
  • Infection spreads to toenails or other areas of skin
  • Feet have an unpleasant odor
  • Symptoms last longer than 2 weeks
  • Fever or pus/discharge present

A doctor can prescribe stronger oral or topical antifungal medications. They can also rule out other conditions like eczema or psoriasis. Severe infections may require antifungal pills to fully eliminate the fungus from the body.

Home Remedies for Toe Fungus Infections

Some home remedies may help treat mild athlete’s foot cases or be used alongside medical treatment. However, these options have less scientific evidence than prescription antifungals.


The acetic acid in vinegar has antimicrobial properties. Diluted vinegar soaks may help treat fungus between the toes. Mix equal parts white vinegar and water and soak feet for 15 minutes daily.

Tea Tree Oil

Tea tree oil has natural antifungal activity. Applying it directly to affected skin or using it in foot soaks may aid in recovery. It should always be diluted in a carrier oil first.

Coconut Oil

Coconut oil has lauric acid which provides antifungal effects. Rubbing coconut oil on feet twice daily may help reduce symptoms. It also moisturizes cracked, sore skin.

Bleach Bath

Diluted bleach baths can have antiseptic effects. Mix 1⁄2 cup bleach into a 40 gallon bath and soak feet for 10 minutes. Rinse thoroughly after. Do not use on broken skin.

Essential Oils

Oils like lavender, clove, and tea tree can be combined and added to foot soaks. Leave feet to soak for 20 minutes. Be sure to mix oils with a carrier oil before applying directly to skin.

When Are Toe Fungus Infections Contagious?

Here is an overview of when toe fungus is most contagious:

  • During active infections with symptoms like scaling, cracking, or blisters
  • If toenails are thick, discolored or crumbly
  • During spread to other parts of the foot
  • When untreated with antifungal medications
  • In warm, moist environments like pools, showers

The fungal spores have the highest concentrations on the feet during active infections. Even after symptoms resolve, spores remain under the nails. That is why proper treatment is important to fully eliminate the infection.

How Long Does Toe Fungus Last?

Duration of toenail fungus infections:

  • Toenail fungus – 12 months or longer without treatment
  • Athlete’s foot – Several weeks to months
  • Infections may come and go without treatment
  • Toenail fungus may last indefinitely
  • With prescription antifungals – Toenail fungus can resolve in 3-12 months

Toenail fungus is harder to treat because the fungi inhabit the nails. Medications have difficulty penetrating the nails to reach the infection. Athlete’s foot infections just affecting the skin respond faster to topical creams and sprays.


Toe fungus is highly contagious in warm, moist environments like public showers. It can also spread between family members at home if shared spaces are not properly disinfected. Practicing good foot hygiene like wearing shower shoes, drying thoroughly between the toes, and disinfecting bathrooms regularly can help prevent transmission.

Treating infections quickly and completely is important to eliminating the fungal spores from the environment. See a doctor if OTC remedies fail to resolve symptoms. With proper treatment and precautions, the spread of athlete’s foot can be controlled.
