A simple wash routine for 3-piece bath mat sets: what to use, which settings to pick, how to dry without damaging the non-slip backing, and how often to wash.
Shake the mats out, wash them on a cold or lukewarm gentle cycle (below 40°C / 104°F) with a little mild detergent, and skip bleach and fabric softener. Then air dry them. Put them back only when the top and the backing are completely dry. In a bathroom that’s used every day, wash bath mats about once a week.
These steps are for Mattona™ Original (HOME) and No Text 3-piece sets, which are machine washable. Each set has two rectangular floor mats and one U-shaped toilet mat. Stone, soft diatomaceous and PVC mats need a different method, so check our care guide by mat type first. Always follow the care label that came with your mat.

Take the mats outside and give them a firm shake, or vacuum both sides. Loose hair and grit come out more easily when the mat is dry, and they won’t end up in your machine.
Wash below 40°C (104°F) on a gentle or delicate cycle, and leave room in the drum so the mats can move. One set per load is ideal. Our supplier notes that long, heavy machine cycles can wear the mats, so a short gentle cycle is best.
Too much detergent leaves residue that stiffens the fibers and holds moisture. Skip bleach, which can weaken fibers and fade the color. Skip fabric softener too: it coats the fibers and makes the mat less absorbent.
Hang the mats over a rail or lay them flat in a well-ventilated room, away from direct heat. Don’t tumble dry Mattona™ mats. High heat can crack or warp a non-slip backing, and a damaged backing is less safe underfoot.
Check the backing as well as the top. A mat that goes back down damp traps moisture against the floor. That leads to smells and can affect the floor underneath.
About once a week for a bathroom that’s used every day. Appliance maker Whirlpool gives the same advice. Wash more often if the mat stays damp for hours after showers, if several people share the bathroom or if pets use it. Between washes, hang the mat to dry after each shower. Here’s how to stop a bath mat from smelling.
Spot clean marks with a drop of mild detergent and a soft brush, rinse, and dry the mat fully. A smell that comes back quickly usually means the mat isn’t drying between uses, so improve airflow and hang it after showers. Never mix cleaning products.
Replace it when the backing peels, cracks or crumbles, when the mat slides or its edges curl, or when it still smells after a proper wash and a full dry. A worn backing is a slip risk, however soft the top still feels.
Not Mattona™ 3-piece sets: air dry them. High heat can crack or warp a non-slip backing. If another mat’s care label allows a dryer, use the lowest heat setting.
Below 40°C (104°F), on a gentle or delicate cycle, with a small amount of mild detergent.
No. Fabric softener coats the fibers and makes a mat less absorbent, which is the opposite of what you want by the shower.
Hang it where air reaches both sides, such as over a rail or the edge of the tub, in a well-ventilated room. Running the bathroom fan or opening a window speeds things up.
