What Should You Wear in a Hot Tub? Swimwear, Etiquette & Hygiene Explained

Relaxing in a hot tub is one of the best ways to unwind, ease muscle tension, and enjoy hydrotherapy at home. But many people overlook an important detail: what you wear in a hot tub matters. The wrong clothing can affect water quality, reduce comfort, and even damage your hot tub over time.

In this guide, we’ll cover what to wear in a hot tub, what to avoid, essential hot tub etiquette, and how your clothing choices impact hygiene and maintenance. Whether you’re enjoying a solo soak or hosting guests, these tips will help you get the most out of your hot tub experience.

The Best Swimwear to Wear in a Hot Tub

Choose Chlorine-Safe, Quick-Dry Fabrics

The best hot tub swimwear is made from polyester, nylon, or spandex blends. These fabrics are designed to handle heat and water treatment chemicals without breaking down.

Why fabric choice matters:

  • Resistant to chlorine and bromine

  • Less likely to release fibres into the water

  • Reduces risk of skin irritation

  • Helps maintain water clarity

Avoid everyday clothing or underwear, which can contain detergents, oils, and fibres that interfere with water chemistry.

Fit Matters for Comfort & Safety

Your swimwear should fit comfortably without being restrictive. Overly loose items can become uncomfortable when waterlogged, while very tight swimwear may reduce circulation during longer soaks.

Look for:

  • Secure but flexible fits

  • Adjustable straps

  • Minimal metal components

What NOT to Wear in a Hot Tub

Avoid Cotton Clothing

Cotton absorbs water, holds bacteria, and releases fibres that clog filters. It can also cause chafing and discomfort when wet.

Skip Makeup, Lotions & Oils

Lotions, fake tan, makeup, and hair products:

  • Disrupt water chemistry

  • Cause foaming and cloudy water

  • Increase filter maintenance

Always shower before entering the hot tub to remove residues.

Hot Tub Etiquette: Personal vs Social Use

Hot tub etiquette plays a major role in hygiene and enjoyment, especially when sharing with others.

Solo Hot Tub Use

When using your hot tub alone, comfort is key — but hygiene still matters. Clean swimwear and showering beforehand will help maintain water quality and reduce chemical usage.

Social Gatherings & Shared Hot Tubs

For social use, etiquette becomes essential:

  • Wear clean swimwear only

  • Shower before entering

  • Avoid eating or drinking in the tub

  • Keep soak times reasonable

Accessories: Are Swim Caps or Footwear Necessary?

Swim Caps

Swim caps aren’t essential for home hot tubs, but they can help:

  • Reduce hair in filters

  • Keep long hair out of the water

  • Improve water cleanliness

They’re particularly useful for shared or frequently used hot tubs.

Flip-Flops & Footwear

Wearing flip-flops around the hot tub helps prevent slips and keeps dirt off your feet. Always remove footwear before entering the water.

Keeping Your Hot Tub Clean & Hygienic

What you wear directly affects hot tub maintenance and water quality. Clean swimwear, proper etiquette, and regular chemical balance checks will keep your spa inviting and safe.
