# 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.
