Introduction
We have all had that moment during a deep Child’s Pose where the scent of a hundred past practices suddenly becomes impossible to ignore. Whether it is a lingering "old mat" smell or visible dirt from an outdoor session, every practitioner eventually reaches a point where a simple surface wipe is not enough. At Hugger Mugger, we have spent nearly 40 years helping yogis care for their tools, and we know that a clean mat is about more than just aesthetics. It is an expression of Saucha, the yogic principle of purity and cleanliness. When your mat is clean, your mind is free to focus on the breath rather than the grime under your fingernails. This guide will walk you through the specifics of deep-cleaning your mat using the bathtub method. We will cover which materials are safe to submerge, the step-by-step process, and how to dry your mat effectively to prevent damage.
Quick Answer: To clean a yoga mat in the bathtub, fill the tub with cool or lukewarm water and a few drops of mild dish soap. Submerge the mat for 5 to 10 minutes, gently scrub with a soft cloth, rinse thoroughly with fresh water, and hang it to air dry away from direct sunlight. This method is best for closed-cell mats like PVC or certain TPE options.
Identifying Your Mat Material
Before you turn on the faucet, you must know what your mat is made of. Not all yoga mats are designed to be submerged in water. Using the bathtub method on the wrong material can lead to a heavy, waterlogged mat that takes days to dry or, worse, begins to degrade. If you are comparing surfaces, our Yoga Mat Guide can help you narrow down the best fit.
Closed-Cell vs. Open-Cell Materials
The most important distinction in mat construction is the "cell" structure. This refers to how the material is bonded and whether it can absorb liquid.
- Closed-Cell Mats: These materials are non-porous. They do not absorb sweat, bacteria, or water into the core of the mat. Most PVC mats, like our classic Tapas® Original yoga mat, fall into this category. Because they do not soak up water, they are excellent candidates for a bathtub soak.
- Open-Cell Mats: These mats are designed to be porous to provide better grip when you sweat. They act like a sponge, pulling moisture away from the surface. While this is great for hot yoga, it makes bathtub cleaning difficult because the mat will absorb a massive amount of water and soap that is very hard to rinse out.
Bathtub Compatibility by Material
| Mat Material | Submersible? | Best Cleaning Method |
|---|---|---|
| PVC (Standard) | Yes | Bathtub soak or surface wipe |
| TPE (Thermoplastic Elastomer) | Yes (Usually) | Gentle bathtub soak or spray |
| Natural Rubber | No | Surface wipe with specialized cleaner |
| Polyurethane (PU) | No | Gentle surface wipe only |
| Cork | No | Surface wipe with water/vinegar |
| Jute | No | Spot clean or surface wipe |
Our Tapas® Original and Tapas® Ultra 74 in. Long Yoga Mat mats are made of high-quality PVC that has been a teacher favorite since 1986. These mats are incredibly durable and can handle a deep soak in the tub when they become particularly grubby. However, if you are using a Para Rubber Yoga Mat, you should avoid the tub. Natural rubber is porous and will absorb water, which can lead to a heavy mat and potential mold if not dried perfectly.
When to Use the Bathtub Method
A bathtub deep clean is not something you need to do after every practice. In fact, over-washing your mat can eventually break down the materials. For daily maintenance, a simple mat refresh spray and a quick wipe-down are usually sufficient. For more routine guidance, our Care & Cleaning Tips for Yoga Mats page is a helpful companion.
Consider a bathtub soak if:
- You practice outdoors: Dirt, grass stains, and pollen can get ground into the texture of the mat.
- You have skipped regular cleaning: If it has been months since your last wipe-down, oils from your skin have likely built up.
- The mat has a persistent odor: When a surface spray no longer masks the smell, it is time for a soak.
- You just bought a used mat: It is always a good idea to deep clean any second-hand gear before your first flow.
Key Takeaway: Submersion is a "deep clean" reserved for every few months or after heavy outdoor use. Regular maintenance should still rely on surface wiping to preserve the mat's lifespan.
Step-by-Step: How to Clean Your Mat in the Tub
If you have confirmed your mat is a closed-cell material like PVC, follow these steps to ensure a thorough clean without damaging the surface.
Step 1: Prep the Tub
Start by cleaning your bathtub itself to ensure there is no soap scum or hair that could transfer to your mat. Fill the tub with enough cool or lukewarm water to fully submerge the mat. Avoid hot water, as high temperatures can soften the adhesives or materials in some mats, causing them to lose their shape or grip.
Step 2: Add a Mild Cleanser
Add a small amount of mild dish soap to the water. A teaspoon is usually plenty. You want just enough to break down body oils without creating a mountain of suds. Avoid harsh detergents, bleach, or heavy fragrances. These can irritate your skin during your next practice or leave a slippery residue on the mat.
Step 3: Soak and Scrub
Place your mat in the water. If it is a long mat like the Tapas® Ultra 74 in. Long Yoga Mat, you may need to fold it loosely or let it curve up the sides of the tub. Let it soak for 5 to 10 minutes. Use a soft cotton cloth or a very soft sponge to gently scrub both sides of the mat. Pay extra attention to the areas where your hands and feet usually land, as these carry the most oil and skin cells.
Step 4: The Rinse (Critical Step)
Drain the soapy water and refill the tub with fresh, clean water, or use a showerhead to rinse the mat thoroughly. You must remove every trace of soap. Any residue left behind will turn your mat into a slip-and-slide the next time you sweat in Downward Dog. Continue rinsing until the water runs completely clear and the mat no longer feels "slimy" to the touch.
Step 5: Initial Water Removal
Once rinsed, do not wring the mat out like a towel. Wringing can stretch the internal scrim (the mesh that gives the mat its shape) and cause permanent warping. Instead, lay the mat flat and press down with your hands to push out excess water, or roll it up tightly and press your weight into the roll to squeeze the water out.
Note: Never put a yoga mat in a tumble dryer. The heat will melt the materials and likely ruin both your mat and your appliance.
The Drying Process: Patience is Key
Drying is the most underestimated part of cleaning a yoga mat in the bathtub. Because the mat has been fully submerged, it will hold moisture longer than you expect.
The Towel Roll Trick: To speed up the process, lay your wet mat flat on a large, clean, dry towel. Lay another towel on top. Roll the "sandwich" up tightly and walk on the roll. The towels will absorb the majority of the surface moisture, significantly cutting down your air-drying time.
Air Drying: After the towel roll, hang the mat over a sturdy shower rod or a laundry drying rack. Avoid hanging it over a thin wire hanger, which can leave a permanent crease in the material.
Location Matters: Always dry your mat in a well-ventilated area out of direct sunlight. While it might be tempting to put it outside to dry faster, UV rays are the enemy of yoga mats. Sun exposure can cause PVC to become brittle and natural rubber to oxidize and crumble. Depending on the humidity in your home, a deep-cleaned mat can take anywhere from 12 to 24 hours to dry completely.
Bottom line: Your mat must be 100% dry before you roll it up for storage. Rolling a damp mat creates a dark, moist environment that is a breeding ground for bacteria and mildew.
Common Mistakes to Avoid
Even with the best intentions, it is easy to accidentally damage your gear. Avoid these common pitfalls when cleaning in the bathtub:
- Using too much soap: It is much harder to rinse soap out than it is to put it in. Stick to a minimal amount.
- Using abrasive brushes: Scouring pads or stiff-bristled brushes can scratch the surface of the mat, reducing its grip and creating tiny tears where bacteria can hide.
- Excessive soaking: Do not leave your mat in the tub overnight. A 10-minute soak is plenty to dislodge dirt. Long-term submersion can lead to water getting trapped in the edges or corners.
- Rolling it up while damp: If the mat feels even slightly cool to the touch, it likely still holds moisture. Give it an extra few hours.

Cleaning Mats That Cannot Be Submerged
If you own an open-cell or natural rubber mat, like our Para Rubber or Nature Collection mats, the bathtub method is not recommended. These mats require a different approach to maintain their integrity.
For natural rubber mats, use a 50/50 mixture of water and organic cider vinegar. The vinegar helps to cut through oils without damaging the rubber. Simply spray the surface and wipe it down with a damp cloth. Natural rubber also benefits from specialized rubber restores that help prevent the material from drying out or "chalking" over time.
For PU (polyurethane) "sticky" mats, use only a very dilute mixture of mild soap and water on a soft cloth. Never use oils or vinegar on these mats, as they can stain the surface and destroy the grip. These mats are highly absorbent, so use the minimum amount of liquid possible.
Maintaining "Saucha" in Daily Practice
Deep cleaning in the tub should be your last line of defense. You can keep your mat in top shape for years by adopting a few simple habits:
- Wash your hands and feet: Most of the grime on a mat comes from the oils and dirt on our own bodies. A quick wash before you step on the mat makes a huge difference.
- Use a Yoga Mat Towel: If you practice hot yoga or sweat heavily, lay a microfiber yoga towel over your mat. The towel absorbs the sweat and can be thrown in the washing machine after every class, keeping your mat much cleaner.
- Wipe after every use: Use a gentle mat refresh spray. For sweat-heavy practice, our Best Yoga Mats for Hot Yoga (2026 Guide) can help you compare moisture-friendly options.
- Air it out: After practice, do not immediately roll your mat and put it in a bag. Let it lay flat for a few minutes so any surface moisture can evaporate.

FAQ
Can I put my yoga mat in the washing machine instead of the bathtub?
While some thin, retail-grade mats claim to be machine washable, we generally advise against it. The agitation of a washing machine can easily tear the edges of a mat or stretch the internal structure. Furthermore, most yoga mats are too heavy when wet for standard home washing machines, which can damage the balance of your appliance. For more context, see our Are Yoga Mats Washable? How to Safely Clean Your Mat.
How long does a yoga mat take to dry after a bathtub soak?
A mat that has been fully submerged typically takes 12 to 24 hours to dry completely. This timeline depends on your local humidity and how much water you were able to remove using the towel roll method. Always ensure the mat is bone-dry before rolling it up, as any trapped moisture will lead to odors and bacteria growth.
Will vinegar damage my yoga mat if I use it in the bathtub?
Vinegar is a common DIY cleaner, but it should be used with caution. For PVC mats, a very dilute vinegar solution is usually fine, but soap is often better for cutting through heavy body oils. For natural rubber mats, vinegar is preferred over soap, but these mats should not be submerged in a tub anyway. Avoid using vinegar on PU (polyurethane) mats as it can damage the surface.
Why did my yoga mat become slippery after I cleaned it in the bathtub?
The most common cause of slipperiness after cleaning is soap residue. If the mat was not rinsed thoroughly, a thin film of soap remains on the surface, which becomes slick as soon as your hands get warm or sweaty. To fix this, put the mat back in the tub and rinse it again with plain, lukewarm water until no more suds appear.
